VoL. vi. MAY, 1898. No. 1
ILLUSTRATIONS OF NEW SHELLS.!
Unio Pilsbryi Marsh, Plate I, figs. 7, 8.
This species is a member of the plicate group of Uniones. It is
a decidedly compressed, oblong shell, black in color, having very
distinctly marked lines of growth, which are spaced over the greater
- part of the disk, but become crowded on the lower margin. It has
numerous oblique waves, which generally bifurcate indistinctly
toward the posterior-lower end. The waves are more or less cut by
short impressed furrows, asin U. undulatus, etc. The nacre is white
and very thick anteriorly, but in the cavity of the valves and pos-
teriorly it is thin and stained with blue and olive-green. The lat-
eral teeth are also olive-green. |
It was collected by Mr. Elwood Pleas in the Little Red River,
Arkansas, and the original description, by Mr. Wm. A. Marsh, will
be found in the Nautitus, V, p. 1.
Unio Pilsbryi is not closely allied to any other American species.
It has a striking resemblance to Unio Leai Gray of China.
Specimens, including the individual figured, are in the special
exhibit of United States shells, formed by the American Association
of Conchologists, in the Museum of the Academy of Natural
Sciences of Philadelphia.

SOUTH AMERICAN NOTES.!
BY DR. WM. H. RUSH, U. S. N.
I have been adding lately to my collections many specimens,
nearly all the work having been done near Maldonado, but few spe-
cies being added, and they include the Unios Rhuacoica and
Charmana, a fine, large Anodonta, Azara labiata, Solecurtus Pla-
tensis; and some fine, large, clean specimens of Mytilus Platensis,
taken from the flukes and shank of an old anchor grappled here.
This old anchor proved to be quite a blessing in disguise, for on it
were some fine specimens of Chiton Tehuelchus and C. Isabellei, and
a few large Ostrea Puelchana. In my dredgings since, I have found
a few more Chitons, but always on rocky bottoms and attached to
stones, so that while adding only a few of these, I have been adding
nothing to my stock of the mud-lovers, such as Corbula, etc.
Mr. Burnett, the British Vice-Consul here, while visiting the ship,
told me that he had occasionally found in his garden a large black
slug. The day following proving pleasant found me on my way to
hunt the monster, but anxious as I was for the little game of hide
and seek, I found time on the way to loiter in a small patch of
native trees to hunt for my old friends, the Helix costellata d’Orb.,
to add to the number of my accumulating exchanges. Finally I
found Mr. Burnett and we started for the old ruins of a house. I
did not anticipate much success when we entered the enclosure, for
the ruins were in the center of the town of Maldonado, whose popu-
lation is about twelve hundred, and the surroundings were
extremely dry, there having been no rain for months. However,
with willing hands we started in and after turning over many large
masses of brick, my companion said, after the exertion of moving
an extra heavy one allowed him to recover enough breath to speak,
“There is one of those large mail-coated insects I was speaking of,”
promptly said, “ Hold on!” and proceeded to turn out with my

spondent, Dr. Wm. H. Rush, dated U. §. S. Yantic, Maldonado Bay, Uruguay,

forceps what seemed to be the veritable monster in all his glory of
zestivation, the Vaginulus solea d’Orbigny, or more correctly
according to Tryon, Veronicella. One more specimen was found
with its egg-nest. Both specimens were curled, and the tentacles
were not visible, in fact, it looked like a lifeless mass of very dark
grayish-brown opaque glue, with lighter gray spots: about the size
of that warred-upon Bland dollar, with a notch in one side and a
crack. extending nearly to the center. Turning it over it presented
the well known under surface as shown in d’Orbigny’s figure. Soon
two tentacles came forth, which stuck up in the air, and each had a
bright black eye visible in the exact center of its free end; then
two more were observed, which projected downward and were
broader and stouter than the others, and appeared bifurcated ; these
latter were constantly in motion, apparently acting as feelers, and
later when the animal was moving along on a glass plate seemed
to act assuckers. Finally he slowly straightened out until he was
ten centimeters long and a little over two wide. I next took a look
at the nest, of which I had found several in the woods, only never
very large, usually containing about ten or fifteen eggs, but in this
one I counted seventy-five, although, much to my discouragement as
an amateur artist, in my sketch of it I can only account for forty-
five—it was about the size of a silver half dollar and hemispherical,
the eggs being regularly arranged around the circumference and
held together by a heavy mucous-like rope. The eggs were oval in
shape, some perfectly clear and transparent, others yellowish and
more or less opaque, and all were covered by the stercoraceous
deposit of some insect, I judged. Unfortunately, it broke to pieces
before I reached the ship on account of the rough handling of curi-
osity. One specimen of the solea was much darker in color than
the other, and the lighter seemed to fade before I had my water
color sketch finished ; subsequent finds may show considerable varia-
tion in coloration. I killed the first specimen in a solution of
bichloride of mercury, 1 to 500, and then dropped it into glycerin
hoping thus to preserve its colors, but it has contracted and become
very dark: the second I killed in the same solution, in which it still
remains. In dying it threw out much mucus, most rapidly and in
greatest quantity from the extreme end so that I suspect there may
be a mucous pore there; it also seemed to come from its whole sur-
face enveloping it quickly in a cloud, completely hiding it, and in
sufficient quantity to render the fluid as nearly opaque as milk.
4 “THE NAUTILUS.
The mantle retracted from the head, which thus exposed is one cm.
long—the jaw was easily seen, by the unaided eye, as a brown cres-
centic band in the superior lip, and with an ordinary magnifying
glass the ridges were easily seen. The whole animal is faded and
contracted, but still pliable. The next I obtain will be killed
in accordance with your directions in water, and will be kept for
ou.
‘ Associated with the solea, and in damp places, I found some num-
bers of the slug which is given in d’Orbigny as Limax unguis Fer.,
but they are not as large as represented in the plate. I found this
latter species very plentiful in the Prado at Montevideo and always
several individuals together. This latter isin contrast with Veroni-
cella, which were alone and widely separated.
I had a few Chitons of both species mentioned in the first part of
this letter, alive in my aquarium bottle, for a few days in my room,
with a long strip of glass upon which I coaxed them to craw] for
the purpose of sketching for water-color work, and was surprised at
the rapidity with which they travel, and it was rendered all the
more decided when I compared it with the movements of the Ver-
onicella which I had in another bottle alongside.
CONULUS FULVUS MULL.! VAR. DENTATUS, N. V.
BY DR. V. STERKI.
Among a number of Con. fulvus from Jackson Co., Alabama,.
kindly sent by Mr. H. E. Sargent, last year, there were a few speci-
mens with distinct “teeth” in the base of the last whorl. Since
then, Mr. Sargent has paid attention to the matter, and a few days
ago sent me some more specimens in two lots, one from the valley and
another from the hills. The latter were most small, young and half
grown, and most of them showed 1-2-3 small, white, testaceous.
deposits in the base of the last whorl, at somewhat irregular inter-
vals, roundish or elongate in a radial direction. They are not high,
tooth-like, but quite distinct, whether seen through the shell, or if
near enough, from the aperture inside, and recall the same feature
‘The species was first described by Miiller, not by Draparnand. It may
be said again, that Comu/us is a genus founded on anatomic characters.
THE NAUTILUS. 5
in the smaller Gastrodontas, although I have never seen more than
one tooth on the same radius. But, as said, in some they are in the
form of radial bars, and when two or three are present they are
always of the same character, either round or transverse. Two
examples, mature or nearly so, but weathered and opaque, have at
least one distinct round deposit each, about + volution above the
aperture. In the specimens from the valley, about a dozen in
number, varying from young to large, and by the way a few of
them with very high spire, there is not a trace of teeth to be seen.
This is certainly a very interesting fact, and the character
described could mean a different species, and for the Nouvelle Ecole
- would be sufficient to establish a new genus. But as the shell is, in
all other regards, formed like that of typical C. fulvus, we have to
regard it as a variety of that species, the more so since in the lot
there are a few examples without teeth and differing in no way from
the type. This, and the variation in number, shape and size, show
it to be a newly acquired character, which some time may be that of
a distinct species.
It remains to know whether the form be found also in other
places of our country—which is quite probable—and to ascertain
also the nature of the localities where it lives. Another question is
whether it also inhabits the Old Continent.
It may be mentioned here also that there are two different forms
of the common C. fulvus, one more pale horn, the other deep wine
or amber colored, and there are also differences in surface sculpture.
It would be of interest to know how far these forms are constant
and in correspondence with the nature of their habitats. I have
seen them in both Europe and North America.

POLYGYRA SUBPALLIATA, N. SP.
BY H. A. PILSBRY.
Some time ago the writer received from Prof. A. G. Wetherby, a
suite of the land snails found at his home, “ Roandale Farm,” Mag-
netic City, North Carolina; and with them a letter giving the col-
lector’s impressions and conclusions in regard to some, and queries
6 THE NAUTILUS.
respecting other forms. A number of “Zonites” were included,
among them specimens of Z. carolinensis Ckll., and of two new spe-
cies, one of about the same size as suppressus, the other larger. Of
these an account will be given later. Among the Helices, one of |
the most interesting forms was labelled “ H. wetherbyi Bld. var. Don’t
believe it!” Upon glancing at the specimens I was compelled to
join Wetherby in his scepticism, for the shells are certainly unlike
H. wetherbyi, and belong to quite a different group of species. The
first notice of these so-called wetherbyi appeared in a paper written
by Mr. Wetherby on the shells of Roan Mountain, and published in
the Journal of the Cincinnati Society of Natural History, vol. iv,
as long ago as 1881. The paragraph is as follows:
“ Mesodon wether byi Bland.—Shells which have been referred to
this species occur somewhat sparingly at this locality. Like the
specimens from the original station, the shells are covered with a
thick coating of dirt, imbedded in the hirsute covering of the epi-
dermis, which being carefully washed away leaves the shell of a
pale greenish white color. These shelis have a lamellar projection
on the inferior surface of the peristome much like that of some
varieties of 7. appressa, and which is a character very distinct from
that of the same region in the type. A very careful examination
of the genitalia shows them to be much more like those of Triodop-
sis. Indeed, looking over the whole field, it seems not improbable
that here we have another case of the union of characters of Meso-
don with other groups, like that of Stenotrema, mentioned in my
notes, No.1. Mr. Binney says, Terr. Moli., vol. v, p. 301, “ Trio-
dopsis does not differ from Mesodon or Polygyra in the character of
its jaw.” Again, p. 306, he says that the genitalia of 7. appressa,
resemble, in certain features, those of Mesodon sayii=M. diodonta.
This shell certainly presents as many features that would ally it
to Triodopsis through appressa, as to Mesodon through dentifera.
In fact, I am inclined to the belief that the shell is not Mesodon
wetherbyi at all, but a distinct species, probably a Triodopsis, and
having the closest analogy to M. dentifera Binney, which certainly
has some very strong claims to relationship to Triodopsis through
T. appressa. The station of this species is always in the dirt under
and beside rotting logs. It is very sluggish and timid, and very.
rare.”
It will be seen that Wetherby recognized the Triodopsoid affini-
ties of the snail; but in the writer’s opinion it is more nearly allied

to the padliata than the appressa. The species may be diagnosed as
follows :
Polygyra (Triodopsis) subpalliata nu. sp. Shell depressed, thin,
pale green or buff-green, somewhat translucent. Surface shining,
minutely roughened by narrow granules elongated in the direction
of growth-lines. Spire convex, composed of slightly over 5 convex
whorls, the last rounded at the periphery, deflexed in front, and
very deeply constricted behind the lip. Aperture oblique; outer
lip flatly reflexed, white, wide, the arcuate basal lip bearing a long
plate-like callus, as in H. palliata; parietal wall bearing a large,
high, curved tooth, like that of H. palliata. Alt. 93, diam. 15 mill.
(largest specimen). Alt. 7, diam. 13 mill. (smallest specimen).
DALL’S TERTIARY MOLLUSKS OF FLORIDA.!
This second volume of Dr. W. H. Dall’s great work upon the
Tertiary Mollusks of Florida is much wider in scope than the pre-
- vious part, including much matter upon other East American
faunas of the same epoch, notably the Pliocene of the Carolinas.
The introductory chapter graphically describes the series of changes
of shore line and elevation of our southeast coast, from the close of
the Eocene to the present time; and this has been noticed and
quoted from in a previous number of the Nautius.
The systematic enumeration and description of species occupies
the greater portion of the work, the subject being completed down
to the Pelecypods, which will form the third part of the work.
The new genera and subgenera proposed are as follows: Glypto-
styla (type G. panamensis Dall), a peculiar form like Pyrula outside
but ponderous and with the plaits of Zatirus. Trachyodon, new
subgenus of Chiton for C. eocenensis Conr.
The generic synonymy of Vivipara is worked out in full, the
author concluding that Vivipara (Martini) Lamarck, has priority
over the very bad masculine form, Viviparus Montf., which has
lately been adopted by English authorities. Incidentally the his-
tory of the name Bulimus is discussed, and shown to be totally
inapplicable to the genus of land snails generally known by that
name. Clava, of Martyn, is used as a generic name to supercede

Vertagus. The genus Natica as used by most writers is definitely
divided into two genera, Natica, in which the operculum is shelly,
and Polynices Montfort (1810), in which the operculum is thin,
flexible, corneous.. The last group contains, of course, the familiar
duplicata and heros of our east coast, and the similar western spe-
cies. This is a division heartily to be commended, and it is surpris-
ing that it has not been placed upon a firm basis long ago.
A very large nuinber of new species are described. The illus-
trations are excellent, having the merit of great clearness of detail.
The appearance of the volume is highly creditable to the Wagner
Institute, the officers of which have, with an enlightened apprecia-
tion of the importance of the work, spared no pains or expense in
its production. Especially are the thanks of both Paleontologist
and Conchologist due to Messrs Joseph Willcox and Charles W.
Johnson, who collected much of the material, as well as to Dr.
Dall who has so ably worked it up.
CESARE MARIA TAPPARONE CANEFRI.
On the 6th of August, 1891, CesarE TAPPARONE CANEFRI
expired after a long illness. Professor CrsARE TAPPARONHE
CANEFRI was born at Alexandria on the 5th of February, 1838,
being descended from a noble Piedmontese family. His father was
for many years Mayor, and destined his son for an official career-
Tapparone, therefore, at the age of 20, entered the University of
Turin as a law student; but he had already become interested in
the natural sciences, especially botany. At Turin he formed a
friendship with Lurat BeLLaRpt and VITTORE GHILIANI; and ir
the elevating atmosphere of that fellowship he developed the:
enthusiasm and love for science which pervaded his whole after life.
A few years after his graduation, Tapparone was employed in the
civil service of Spezzia; and there he was attracted by the rich
shell fauna of the Gulf, which had already been studied by JEF-
PREYS and CAPELLINI. Many species not known to these students.
were found by the young enthusiast, who, in 1865, embodied the
results of his research in a “Catalogue of the Mollusca of Spezzia,”
his first conchological paper. Henceforth, the greater part of his:
time was given to the study of mollusks. He shortly became an
assistant to Professor Lessona, in the Chair of Zoology and Com-
THE NAUTILUS. g
parative Anatomy, in the Royal University of Turin; while here
he worked up the mollusks collected by pE FiuipPe during the cir-
cumnavigation of the Royal Frigate, ‘Magenta. In 1873,
Tapparone began the series of articles upon Oriental land mollusks
collected by O. Beccarr and L. M. D’ALBerRtIs in New Guinea
and adjacent regions; and it is to this series of papers that his
reputation is chiefly due.
After a residence of eight years in Turin, Prof. Tapparone went
abroad for the purpose of studying the mollusks of foreign
museums. He visited the British Museum, the Zoologicai Museum
of Berlin, etc., and finally spent some time in study under SEMPER
at Wirzburg. Returning to Italy, he went to Genoa, where he
devoted himself to the mollusk collection of the Civic Museum.
Shortly after, a disease of the circulation and nerves manifested
itself, and despite the tenderest care of wife and friends, it proved
fatal.
His collection and library have been given to the Civic Museum
of Genoa, by his wife.
All students of land shells will regret the death of so conscien-
tious and able a malacologist ; and particularly will his loss be felt
by those who have profited by his “ Fauna Malacologica della Nuova
Guinea,” and the other essays upon allied faunas.
A bibliography and full biographical sketch by IssEL, with por-
trait will be found in the Annali del Museo Civico di Storia Nat-
urale di Genova, 1892.
THE UNIO MUDDLE.
BY PROF. CHAS. LE ROY WHEELER.
Under the above heading appears an article in the February
Navtiuvus from the pen of Mr. Berlin H. Wright. In a recent
number, also, appeared an article from Mr. John H. Campbell sug-
gesting that the Uniologists connected with the American Associa-
tion of Conchologists meet at Chicago this summer and settle dis-
puted points as to priority of description, nomenclature, and syn-
onymy. Certainly it would be “just too nice for anything” if the
aforesaid Uniologists could have a little pic-nic at Chicago, pass
a few resolutions forever settling all disputed points, pat each other
10 THE NAUTILUS.
on the back, shake hands, adjourn, go home, and sleep more soundly
then ever before; but, unfortunately, the ghosts of Dr. Lea, Mr.
Conrad, Mr. Say, and others might appear upon the scene, and
Mr. Ego might appear in the flesh, armed with carpet-bag, micro-
scope, and manuscript; in which case the big show would not last
half long enough to enable the quarrelsome scientists to finish throw-
ing mussel shells at one another.
Seriously, however, this “ muddle” ought to be unmuddled; but
how is it to be done? Who is there upon whom all concerned will
be willing to rest the responsibility of deciding contested points?
Can three or five men be found upon whose judgment all will con-
sent to rest? Ifso, who shall they be?
By the time the “ Unio Muddle” shall have been fairly settled
the indications are that there will be three or four other first class
muddles ripe. Would it not be well for the American Association
of Conchologists to do in regard to American mollusks as the Amer-
ican Ornithological Union has done in regard to the American
Birds, and settle not only the “Unio Muddle,” but all contested
points in American Conchology?
Why is it that the reputation of a conchologist should rest upon
the naming of new species rather than upon a knowledge of Con-
chology? and, honestly, may not the making of new species some-
_ times be attributed more to conceited self-assertion than to a desire
to help the science? Suppose we have a committee of the American
Association whose duty it shall be to decide upon the merits of
so-called new species, and that a name be regarded as only provi-
sional until it be accepted or rejected by such committee. So mote
it be.
DESCRIPTION OF A NEW SPECIES OF NASSA FROM THE GULF OF
CALIFORNIA.
——————_
BY ROBT. E. C. STEARNS, U. 8S. NATIONAL MUSEUM.
Shell small, elongated, ovate, of seven to eight whorls, with an
acutely elevated spire, ornamented with generally three spiral ser-
ies of granules; occasionally four series are exhibited on the penul-

SOME NOTES ON ZONITIDAE.
BY, DR. V._SfERKI.
1. The generic name Zonites Montf., has, by European malacolo-
gists, long ago been restricted to a.group of circum-Mediterranean
forms, such as algirus, verticillus, gemonensis, etc., none of them
being represented in the recent North American fauna; and as it
seems to be a well-defined genus, we will do well to recognize this
restriction of the group. The old genus Zonites, or Hyalinia, is
being disintegrated, just as the old genus Helix has been. For
nitidus Miller, the genus Zonitoides has been established on charac-
ters chiefly anatomic, the presence of a dart sac and dart, and, as it
seems, peculiarities of the radula. As the same dart sac and dart is
present in a number of North American species, such as elliotti,
ligerus, demissus, intertextus, gularis, suppressus, internus, etc., and,
as has been supposed, and I can positively confirm, arboreus—they
would range under Zonitoides, especially if their anatomy prove to
agree with nitida, also otherwise. Dr. vy. Ihering makes the propo-
sition to unite all Vitrino-zonitidae having a dart’ in a family, as
xiphogone forms—“ Zon.” (or Hyal.) fulvus Mill., gundlachi Pfr.,
sterkii Dall., belong to the genus Conulus Fitz., well characterized
anatomically. Hy. crystallina Mill., diaphana Studer., etc., of the
old continent, have their peculiar anatomy also, and range under
+ Which, however, is not homologous with the dart of the Helicidae, and there-
fore named fugio, by v. Ihering.
14 THE NAUTILUS.
the genus Vitrea Fitz. On the other hand, as well known, our
Mesomphix (8. str.) are hardly to beseparated generically from Hya-
linia (Euhyalinia), as glabra, draparnaldi, cellaria, etc., and forms
like our wheatleyi, petrophila from pura, ete., not to speak of radia-
tula which is equally distributed on the old and new continents.
We may, for all these, use the generic name Hyalinia, the more
since such authorities as W. G. Binney, Tryon and others have done
so before, and no embarrassing of the synonymy will result. Yetall
these forms still need careful examination as to their anatomy.
2. Some Zon. suppressus Say, show not a trace of internal teeth or
rather lamelle, when adult; W.G. Binney (l. c. p. 226) also says
that the tooth is sometimes “so little prominent as to be hardly
visible.” I have in possession specimens from Ohio and Virginia
(Petersburgh, collected by myself) of 7-8 mill. diam. and 7-72
whorls, with the last whorl and aperture well-rounded, without any
“teeth,” and only a thin callus inside. As to size and shape, they
differ essentially from W.G. Binney’s description and figure.” With
these, there were examples of all ages and sizes, inseparately con-
nected with the former, having two strong lamelle upon a heavy
callus. Also in gularis and other forms of the group, the lamelle
considerably decrease in size and number with advancing age, and
at maturity sometimes are quite short and thin.
3. Mrs. Geo. Andrews, to whom we owe so many valuable finds
among land mollusca, sent me, in 1891, anumber of “ Zonites gularis
small var.’ Then I was satisfied that they were not gularis; and
now, aiter repeated comparison and examination also of the soft
parts on specimens recently obtained, this is beyond a doubt, and as
well, that it is a distinct species, not yet described. Here only so
much of the description will be given as to serve our purpose. The
shell is of the general appearance of a small Z. ligerus, of only 9
mill. greater diameter, finely perforated, with a high spire, well-
rounded at the apex. Inside there is a rather long fold correspond-
ing to the same (outer) in Z. gularis, etc., and a lower one near the
columella. In a part of the specimens there is another (outer) long
fold, about 4—-} volution above the aperture, sometimes connected
by a fine marking with the one in front; evidently this is the one
previously formed and not resorbed, the same thing as in Z. internus,
etc.
4, A few examples of Zonites, I| think a form of demissus, from
2 Manual, p. 225; fig. 241, looks like drawn from an immature specimen.
THE NAUTILUS. 15
Nashville, Tennessee, and Jackson Co., Alabama, the latter collected
by Mr. Sargent, have a strong, thick, white, testaceous deposit
inside the base of the last whorl, with some nodules, apparently
irregular, but equal in the specimens from either locality, which
correspond to teeth or folds. ‘These testaceous deposits in different
species are often smaller and thinner in mature shells than in ado-
lescent, and sometimes entirely resorbed; they evidently are the
same morphological element as the deposits and folds in Gastro-
donta.
5. I believe the fact must impress itself upon anyone that Zon.
suppressus, especially the form noted above; gularis, also more in
some forms, much resemble Z. ligerus, demissus, etc., and are nearly
related to them, much more so than the latter are to the Mesomphix
between which they are inserted in systematic works. This feeling
found its expression also in W. G. Binney’s “ L. & F. W. Shells,”
where ligera, demissa, intertexta are ranged under the genus Hya-
linia, the Mesomphix under Zonites. To this now comes the species
announced under 3 above, resembling /igera as to the general con-
figuration of the shell, and “ Gastrodonta” in the lamelle, which
are of a somewhat peculiar type at that, approaching it to signifi-
cans Bld. Some light on the significance of; mone or absence of
internal teeth is given also by Conaulus/ Sus ws, i» ~vhich, as we have
seen, such may be found or wanting in ‘!f% same form from the
same locality. And a character common to the two groups, valu-
able even of higher order, seems to be the presence of a dart, in the
genital organs, which would range them together in the genus Zoni-
toides. It may be communicated here, previously, that I have
found, in the upper part of the penis in Z. ligerus, suppressus, the
forms mentioned under 3 above, and in arboreus a peculiar papilla
(Reizkérper of German authors) in which a part is hard, sharp,
projecting and (in the 5 former species) impregnated with carbonate
of lime.
6. Quite lately, Mrs. Andrews has sent me specimens of a Zonites,
collected at Cranberry, Mitchell Co., North Carolina. They can
be referred to none of the described species, and may prove to be a
new one.’ The shell, of about 7 m. in diam., has two very small
lamelle or teeth near the aperture, corresponding to the same Z.
’ The n. sp., however, may be ‘‘ hanged in the smoke till cured,” or left in
suspense till fully confirmed; it is, 25 swch, of little consequence, but of great
_ importance as a form.

gularis, and thus proves to be a Gastrodonta. The shell is thin,
transparent, somewhat greenish deep horn colored, of the,ysame
appearance as Z. nitidus Mill., which species it surprisingly resem-
bles below, while above it appears different by the greater number of
whorls. It seems that here we have a “ missing ” or connecting link
between the so-called type of Zonitoides, and its more characteristic
North American members. .
7. Mrs. Andrews has, of late, again sent me numerous small
Zonitidae, collected in the mountains of Tennessee and North Caro-
lina. From these I learned, beside other things, that Zon. andrewsi
W. G. B., when adult, has very often (or always?) no internal teeth
at all. Moreover, the shell attains quite a different configuration:
the last whorl is placed considerably deeper on the penultimate, or
gradually descends, thus causing the spire to be much more ele-
vated ; it becomes also deeper and at last somewhat truncate in the
periphery (perpendicular section) and subangular below, compara-
tively large, just as we find it in some ligerus, gularis, suppressus.
At the same time, the base is no more equally rounded, but becomes
sloping inward, somewhat infundibuliform, the umbilicus is rather
large, and the striation becomes more crowded and coarse, even so
that the strize appear to be raised (7. e. the intervals) in place of
impressed, as they are on tie lunex whoris. The whole shell then has
quite a different appearance from that conxxonly known as Z.
andrewsi, much resembling the description and figure of Zon. placen-
tulus Shuttl. (in W. G. Binney’s Manual, p. 222). The whorls are
fully 9 or more, the diameter 7-7°5 mill. It was somewhat difficult
to state these relations, as I had, though, a good number of speci-
mens, no complete series from one locality at disposition. There is
no doubt, to say no more, that many such examples have been
taken for Zon. placentulus. And, asa striking proof of this, I have
in my collection four specimens from the mountains of North Caro-
lina received as Zon. placentulus, years ago, from a conchologist who
studied those land shells; they show more or less the characteristic
features noted above, and one of them has a distinct row of denti-
cles denoting it unmistakably as Zon. andrewsi.
8. As with the preceding, it is with Zon. significans Bld. Only the
younger examples, i. e., those commonly found in collections under
this name, have the teeth, two series of two, as a rule. In older
specimens, of 5-6 mill. diam., they are no more formed, or only
occasionally one or another, and then the shells have the characters
THE NAUTILUS. say
of capsella Gld., and doubtless have been and will be taken for such.
A lot of fine examples, received from the same author, collected in
eastern Tennessee, and named capsella, are, to all probability,
nothing else but adult significans, in which the last whorl becomes
comparatively more voluminous and commonly more descending.
The spire is variable from almost. flat to rather elevated, and also
the umbilicus shows some differences. Among lots, which to all
appearance, were Zon. capsellus, there were examples with a single,
sometimes barely perceptible, tooth.
9. With all this, I do not feel positive, at present, that Zon.
andrewsi W. G. B., and stgnificans Bld., are only the juvenile
forms of Zon. placentulus Shuttl. and capsellus Gld. But so much is
sure, that they must be desperately similar, respectively, and that
they need careful revision, also as to anatomy. The words of W.
G. Binney that the latter form “a puzzling group,” become of an
increased meaning now.
10. For faunistics, it may be of interest that there were a few
specimens of Hyal. ferrea Mse., from eastern North Carolina,
among the materials sent by Mrs. Andrews. In my collection
there is one from Randolph Co., West Virginia. Also from differ-
ent places in eastern Ohio it is known.

A REVIEW OF VON IHERING’S CLASSIFICATION OF THE UNIONIDE
AND MUTELIDE.
BY CHAS. T. SIMPSON.
Since the theory of evolution has been generally accepted, a com-
plete revolution has taken place in the methods of study and classi-
fication among biologists.. All artificial systems, or those based
upon a single character, have either been relegated to the past or
are hopelessly doomed. Students who are progressive and keep
abreast of the times, realize that in the study of organic life it is
necessary to seize on to every fact which can possibly aid them in
classifying: embryology, anatomy, the study of its development in
the past as taught by palaeontology, geographical distribution and
habits. :
Dr. H. von Ihering, of Rio Grande do Sul, Brazil, has recently
18 THE NAUTILUS.
published in Archiv fiir Naturgeschichte,’ a lengthy article on the
Najidae of San Paulo, Brazil, and a proposed system of classifica-
tion in which some startling discoveries are brought to light, and
which ranks as one of the ablest papers ever written on the subject.
This classification, while working a complete revolution in our pre-
conceived ideas of the relationships of the different members of this
group, is so clear and philosophical, it so thoroughly takes cogni-
zance of all the known facts, that it is certainly worthy of the most
thoughtful consideration. In a brief review like this I can only
allude to the more prominent points, and those who are interested
should read the paper itself. |
H. and A. Adams, in the Genera of Recent Mollusca, divide the
Naiades into two families, Unionide and Mutelide,’ separated by cer-
tain minor characters of the shells and animals. Ihering uses the
same family names in a somewhat different sense from the Messrs
Adams, and unites the whole intoa larger group or super-family,
which he calls the Najide. He finds in all the genera which he
places in the Unionidae, the larval state is a glochidium, that is, a
stage or condition in which the animal is completely enclosed in a
porous bivalve shell.
On the other hand, the species which he places in Mutelide, pass
through a state after hatching which he calls a dasidiwm, in which
the animal is divided into three parts, of «which only the middle
bears the small, single shell. He finds, on examination, that those
South American forms that have hitherto been placed with Anodon,
pass through the lasidium stage, hence they must be separated
from that genus whose larval state is a glochidium, and he retains
for this group the name suggested by Gray—Glabaris. He believes
that Aplodon, having a few South American species, hitherto placed
in Monocondylea, and the so-called African Anodons belong to the
same family, and that the latter should be placed in Glabaris.
D’Orbigny established the genus Monocondylea for certain species
of South American Naiadae whose shells possess a single cardinal,
and no lateral teeth. Several of these will fall into other natural
groups. Ihering does not mention the Asiatic species which Lea

and others have placed in this genus, but I believe they have no
close relationship to these South American forms, and that they are
merely depauperate Unios, which have a close affinity to species of
that genus found with them.
The Unionide of Europe, North and Central America, and prob-
ably of the whole Northern Hemisphere, develop eggs in the outer
gills alone as far as is known, with the exception of Unio multiplica-
tus and one or two others, which contain embryos in all four leaves
of the branchiae. Ihering states that in all the Najidae hitherto
examined from South America, the eggs are borne in the inner
gills. I may remark in passing that the shells of the Australian,
New Zealand, and many South African Unios bear an astonish-
ing resemblance to those of South America in form, texture, smooth
epidermis and concentric, sometimes slightly granulated sculpture,
and especially in the peculiarly compressed, parallel cardinal teeth,
and Suter states’ that the embryos of N. menziezi are borne in the
inner gills. Ihering calls attention to the fact that all South Ameri-
ean Unionide have a radial beak sculpture, and suggests that prob-
ably the same character may be found in the New Zealand species.
I have carefully examined extensive series of Unio menziezi and
lutulentus, and on the latter find that the umbos are radiately
ribbed where the shells are not too badly eroded, and there are
traces of such ridges om the former and ¢\ seme Australian species.
He believes that we shall find the beak sculpture one of the best
characters for determining the minor divisions of the Unionide.
Notwithstanding the opinion of this eminent conchologist, and the
fact that Mr. Wm. A. Marshall, of the New York State Museum,
who has also given this subject some very careful study, believes that
the beak sculpture is quite constant and may be used in determining
species, my own experience in handling great quantities of material
from all over the world leads me to consider this a somewhat varia-
ble character, and although it will no doubt prove very useful in
studying species and the smaller groups, yet I am sure it cannot by
any means be always relied on.
It is only in Europe that the post-embryonic larve of the Union-
ide have been observed actually attached to fishes, though the
North American species are known to possess hooks and bristles
during this stage, and they no doubt make use of the same means to
assist in their distribution, as do their Old World relations.

20 THE 7S |
Ihering fails to find them on any of the South American Union-
ide he has examined, but he has probably overlooked the statement
of Lea‘ that theaglochidium of Unio firmus of Brazil is provided
with both of these appendages.
Castalia was placed in the Mutelide by the Messrs Adams,
but Ihering shows that it is very closely and curiously related to
Unio. In the latter the short branchial siphon is open; in the
former it is closed; in Unio the lateral teeth are either smooth or
obliquely striated ;? in Castalia they are vertically ridged. He has
applied the name Castilina to a few species which stand between the
two genera, and has given it generic rank. But he shows that
there is a complete intergradation and connection from one end of
the chain to the other. In certain Castalias there is a typical ani-
mal, in others it is that of Unio, and in Castalina there is an almost
complete blending and crossing of characters. I have noticed on
examining large series of these shells that in some Castalias the
peculiar tooth sculpture is nearly wanting.
Von Ihering finds that Unio multistriatus of Brazil is very closely
related to N. senegalensis of Africa, and to certain Indian forms.
He has, in his collection, a specimen of Unio radula of India that is
identical with N. coriaceus from Rio Janeiro, and believes this fact
to be a proof of the long duration of the species of this family and
probably evidence in fay r of tue existence ofthe lost Atlantis.
His arrangement of the families and genera staads as follows:

2In Unio tortuosus Lea, a remarkable inequivalve species from China, the
laterals have perpendicular striae, and Lea remarks that if this is found in all the
individuals of the species, it would have to be placed in Cas¢avia. It has much
the appearance of Unio e/lipsis Lea.
THE NAUTILUS. 21
This classification is, to a certain extent, provisional; and may
have to be somewhat modified when we have a fuller knowledge of
the anatomy. Whatever else may be said of it, the principle
adopted is the right one, and the only one which modern science
can recognize. The arrangement of the Adams brothers is largely
artificial, both as to genera and subgenera, as well as the system
adopted by Lea, as they bring together side by side, species and
groups from every country which have no close relationship what-
ever, and by such methods anatomical and conchological characters,
the facts of geographical distribution, habits and paleontology, are
ignored,
THE SMALL GREY SLUG IN JAMAICA.
BY T. D. A. COCKERELL.
Some days ago Mr. W. Harris sent me from Cinchona some
strawberry plants, together with a beetle larva which was injuring
them. Of this larva there will be more to say hereafter, but the
object of the present note is to record that among the plants I found
three specimens of the small, grey slug of Europe, A griolimax agrestis.
This slug, well-known as a gerden pest in England, has never before
been noticed in the West Indies, and there can be no doubt that it
has been introduced with plants. It is, I suppose, almost impossi-
ble to import living plants without sooner or later introducing for-
eign slugs. They and their eggs come in the earth about the roots,
and, in many cases, it must be practically impossible to detect them
on arrival. It might be advisable in some cases to isolate newly-
arrived plants by water, and search for slugs on them at intervals;
or we might import the carnivorous slug, Testacella ; or introduce
some of our native carnivorous snails, Oleacina, into the locality
where the plants were being propagated. It has been recorded that
in twenty-four hours, 25 specimens of Testacella devoured 25 earth-
worms and 25 Agriolimax agrestis.
The small, grey slug, although now first detected here, has
spread to many distant localities by human means. I have seen
specimens from various parts of the United States, west to the
Pacific coast and east to New Jersey, from St. Helena, the Canary
Islands, Tristan d’Acunha, New Zealand, etc., and no doubt in time
‘it will inhabit every part of the earth in which the climate is suit-

able to it. In Jamaica it will probably remain confined to the
higher altitudes.
Institute of Jamaica, April 15, 1893.
A REPLY TO PROFESSOR WHEELER.
I think that quite enough has been said on the subject of the
Unio muddle in the columns of the Nauriius, and I do not want to
revive the subject. But there are one or two suggestive points in
Professor Wheeler’s note in the May number that I want to call
attention to.
While a Congress of American conchologists might be able to
settle certain contested points in nomenclature, if their work did not
come into too glaring opposition to certain established laws recog-
nized by scientific societies in general, yet I believe it is impossible
for any such body to straighten out the muddle of specific limits, or
perhaps, in all cases, the relations of one species to another. I
believe that an expert, a specialist who has devoted years to the
loving study of a family or genus, is better qualified to judge on
these points than any body of students, no matter how capable they
may be otherwise, but who probably have only a mere smattering of
the matter in question.
C. B. Adams and Dr. Gould ranked easily among the ablest
conchologists in the world, but who can doubt that Mr. Lea, or
James Lewis were better qualified to judge on the nice distinctions
of the Unionidae, or that Dr. Newcomb was more competent to
arrange the Achatinellas, or that Dr. Dall has a better knowledge
of deep sea Mollusks than did either of these? Because these men
have made life studies of these subjects, while the others were not
specially interested in them.
A specialist who works on a difficult or puzzling group, goes over
his work again and again, putting it aside when he tires of it, and
taking it up when the mind is rested. He patiently and lovingly
labors over the most minute and obscure points that to most students
would be of little or no interest, because his heart is in the work and
he is thoroughly determined to master the whole subject. As a rule,
his collecting is largely done in the direction of his hobby, and he
therefore has, more material to work on than one slightly inter-
ested. He eagerly reads all literature relating to his work, and in
time, if his judgment is well balanced, he becomes an authority.
THE NAUTILUS. 23
Now I do not pretend to say that any such person can ever
arrive at a point where he never makes mistakes, or where his
authority should be taken as absolute, but I do say that he knows
at sight and has constantly on his tongue’s end much that the ordi-
nary student cannot possibly know or have.
And even when such a specialist publishes the results of his stud-
ies they must stand the test of criticism, merciless and searching;
they must be subject to all the modifications that will be caused by
future discoveries and enlarged knowledge, for it is the naked truth
alone that will stand, and not the assertions of any specialist or
body of scientists. But I believe that the man who spends years of
loving, conscientious labor and study on a subject is better qualified
to act as an authority than any body of outsiders.

NOTES AND NEWS.
Mr. Hueu Futron, of London, passed through Philadelphia,
recently, en route for Chicago. His stay, though short, was most
enjoyable.
Notrr.—Owing to the expected absence from Philadelphia of the
Editors and Manager, the July issue of the Nautrxus will probably
be delayed beyond the usual time.
Last week a coyote was found at Punta Banda, San Diego county,
trapped by an abalone shell [ Haliotis cracherodii|. The coyote had
evidently been hunting for a fish breakfast, and finding the abalone
only partially clinging to the rock had inserted his muzzle under-
neath to detach him, but the abalone closed down on him and kept
him a prisoner.— Weekly Bulletin, San Francisco, May 17.

. TO CONCHOLOGISTS.
The Editors of the Nauritus would like to impress upon Ameri-
can Conchologists that they are not conducting this paper for their
personal aggrandizement, as some persons seem to believe. The
work done has been purely a labor of love, for the promotion of
interest in cunchology; and the Editors have not only put much
work into the enterprise, but, from first to last, a considerable num-
ber. of large and shining Dollars, and this without expectation of
pecuniary return.
We have looked forward to the unanimous support and encour-
agement of American Conchologists, for it is only by such support
that a paper of this character can be sustained. We know that
there are enough persons in the States interested in Conchology to
give this support, and to enable us to increase the size, the number
of illustrations and the interest of the articles as well.
We depend upon you to aid us in bearing the expenses of publi-
cation. We depend upon you to send us notes and matter to
increase the interest and usefulness of the numbers from month to
month. ‘The time we put on this work is time stolen from scientific
work of vastly greater magnitude, and it is only by the liberality of
the Academy of Natural Sciences and the Wagner Institute that
we are enabled to give the attention necessary to conduct a monthly
journal.
We write thus because we know that we are not having the sup-
26 THE NAUTILUS.
port we deserve from American Conchologists. Scores of subscrip-
tions remain unpaid, and requests by letter to “square up” are
calmly ignored.
We would ask our subscribers in all seriousness, Do you need
this paper? If so, why not support it. We depend upon the Con-
chologists of America to help and encourage us in making our
NAUTILUS a journal worthy of American Science.

BULIMULUS PROTEUS Broderip AND ITS DISTRIBUTION.
BY W. H. DALL.
Bulimus proteus was described by Broderip from Peru in 1832.
It was referred by Deshayes to B. sordidus of Lesson, an opinion
not generally adopted, and which he afterward relinquished. In
1860, Mr. J. Xantus, collecting for the Smithsonian Institution at
Cape St. Lucas, obtained one adult and two young specimens of a
large Bulimulus, which were referred to Broderip’s species by Bin-
ney ; an opinion which was justified by the close resemblance and
small amount of material for comparison. The singularity of dis-
tribution has been commented on by every one from Binney to
Crosse and Fischer in their magnificent work on the Mexican Jand
shells, and Dr. Cooper in recent papers on Lower Californian land
shells. By a recent expedition of the California Academy of Scien-
ces to Lower California, nearly 100 specimens of the shell in ques-
tion were obtained, which I examined while in California in 1892,
and which are described by Dr. Cooper (Proc. Cal. Acad., 2d Ser.
III, p. 211, 1892), thus for the first time giving an opportunity for
careful comparison of our Californian species with that from Peru.
A series kindly sent by Dr. Cooper on behalf of the Academy,
together with the original specimens of Xantus and a series of four-
teen specimens of the Peruvian B. proteus, have been critically
compared, leaving no doubt, in spite of the close similarity, that the
Mexican shell is distinct and must receive a name, as the synonyms
are all strictly referable to the Peruvian form.

THE NAUTILUS. 27
As Dr. Cooper observed, this species is not as “ protean” as some
others. It exhibits no such variations in form or color as B. proteus ;
the latter assumes almost every mutation of form, but taken on the
average is less acute and has the last whorl less patulously drawn
out, axially, than the B. montezuma. The color of B. proteus is
variably distributed, but tends in the most strongly colored exam-
ples to be laid on in 4-6 broad, spiral bands of brown, with indis-
tinet boundaries, separated by paler zones. In B. montezuma the
color is seldom present, but, when it is, it is laid on in narrow,
obscure zones, parallel with the incremental lines and never spirally
disposed. The granulation in the Californian shell is less coarse
and intense than in the Peruvian species when most developed, and
the umbilicus averages much smaller in the former. All these char-
acters are of degree rather than kind, but two features may be men-
tioned which appear constant and specific. In the Mexican shell
the angle which the outer lip makes with the body whorl, or axial
perpendicular, at its junction is invariably more acute than in B.
proteus, which latter has the lip bent suddenly down at this point.
Secondly, the larval shell or nucleus of B. proteus is beautifully
shagreened with minute punctations or short, almost vermicular,
indentations, visible plainly under a glass, and only absent when
worn off by abrasion. Traces of this sculpture may always be found.
In B. montezuma the nucleus is delicately ribbed in harmony with
the incremental lines, and does not show the peculiar shagreening
alluded to, a character which alone is sufficient to establish its dis-
tinctness, but the constancy of which could not be predicated from
the three specimens examined by Mr. Binney.
The distribution of the species now determined by Messrs Eisen
and Belding is sufficient to disprove the hypothesis of introduction
by artificial means, and it is satisfactory to have our largest North
American species placed upon a permanent footing.
EDIBLE MOLLUSKS OF SOUTHERN CALIFORNIA.
BY MRS. M. BURTON WILLIAMSON, UNIVERSITY, LOS ANGELES CoO.,
CAL.
In an interesting article upon the “ Edible Mollusks of Rhode
Island,” by Mr. Horace F. Carpenter, published in the Nautrius
some time ago, he compares the number of marine edible mollusks
of Rhode Island with those reported from San Francisco by Profes-
sor Keep.
ys ea THE NAUTILUS.
Without wishing to leave the impression that California can
compete with Rhode Island in the number of species found in the
“fish markets,’ yet the number recently reported from this State
can be greatly increased. The number of shells offered for sale here ~
is always limited, and the famous “clam-bake” of the eastern shore
is never duplicated. In the Los Angeles fish markets, Donaz and
Chione are the most abundant.
Donax californicus Cony. is the favorite clam for soup. This tiny
- bivalve might seem to an observer “all shell,” yet it proves a very
good substitute for the oyster in soup. The shells are carefully
washed, allowed to remain in fresh water some hours, boiled, then
drained. The liquid drained off is, with plenty of milk added, con-
verted into a very palatable soup, especially when one is on the
beach, and has just returned to the tent after a good bath in the
ocean. |
Chione simillima Sby. is often offered for sale at five cents a pound.
Chione fluctifraga Sby. and Chione succincta Val. are occasionally
found with the former, as they are collected from the same mud
flats. Soup made from this shell-fish is not finely flavored and the ~
meat is tough.
Tivela crassatelloides Conr., large shells are sometimes sold in the
markets, usually at five cents each. Tapes staminea Com., Ostrea
lurida Cpr., Ostrea virginica Gmel. (the latter brought here from
San Francisco), Mytilus californianus Conr., Mytilus edulis Linn.,
and Pecten aequisulcatus Cpr., are also occasionally offered for sale,
but in limited quantities. Haliotis eracherodii Leach may some-
times be seen in the market, although I have not seen one this win-
ter. Occasionally a small Haliotis fulgens Phil. has been seen with
the former species. The Mexicans seem to be fond of this shell-fish,
as I have seen three and four dozen Halioti dried and strung on a
cord, the same as they string red-peppers. When dried, the Aba-
lones, as they are named by the Mexicans, look like oblong pieces of
very thick leather, more than anything else that I can describe.
The number of species found in Los Angeles city markets, and
not reported from San Francisco, would, I believe, add six more to ©
the Californian region. Professor Keep says the Mytilus californi-
anus is found outside of San Francisco Bay, but does not mention it _
as sold in the city. Amiantis callosa Conr. is occasionally eaten
when collected in San Pedro Bay, although I have been told it was
“not a very tempting dish.” As it does not live near the shore,
THE NAUTILUS. 29
collectors do not often find more than single valves on the beach.
In the “ Catalogue of Economic Mollusks,” written by Lieutenant
Francis Winslow, upon the exhibition of the U. S. Nat. Museum, at
the “International Fisheries Exhibition,” at London, in 1883, he
says of Macoma nasuta Conr., “It is abundant in San Francisco
Bay, and it was evidently eaten largely by aborigines, as the shell-
mounds in the vicinity of the bay are largely composed of shells of
this species.” I have not heard of this shell-fish being eaten here, nor
the much larger Macoma secta Conr., but Lieutenant Winslow says the
former is “eaten on the Pacific coast by all classes.” The same
writer mentions Platyodon cancellatus Conr. as existing in “ great
abundance in Bolinas Bay and Santa Barbara. Its habits are
essentially those of the ‘soft clam,’ and it forms one of the staple
‘food shell-fish of the Pacific coast,” although Mr. C. R. Orcutt, in
his “ Notes on the Mollusks of San Diego,” says this shell has
_ been collected for food at La Playa, “but the animal is bitter.” I
fear Iam digressing, as Professor Keep’s article was intended by
him as the first of a series of articles reporting “food mollusks
which may be bought in the markets of our country,” each writer
“reporting for his (or her?) own locality.”
Notwithstanding fhe number of species we can report from Calli-
fornia, 1 am compelled to admit that, in quality and number of
individuals, California cannot boast of her edible mollusks.
ON A NEW SPECIES OF YOLDIA FROM CALIFORNIA.
BY W. H. DALL.
_ Yoldia montereyensis n. s.
Shell large, stout, inflated, with a polished, dark greenish olive
epidermis; beaks eroded in all the specimens, situated in the anter-
ior part of the middle third of the shell, not prominent ; valves full
and rounded, anterior end evenly rounded into the upper and
basal margins; posterior end narrower, rounded, the extreme end
nearer the cardinal margin with which it almost forms an angle,
below sloping obliquely toward the basal margin, with a very
obscure broad ray impressed in a radiating manner from the
beaks toward the oblique slope, the profile of which it does not per-
ceptibly indent; surface sculptured only by feeble incremental lines;
epidermis polished with one or two darker concentric color zones
and a microscopic, irregular, radially disposed wrinkling, most con-
30 THE NAUTILUS.
spicuous at the margins of the impressed ray; posterior cardinal
margin nearly straight, anterior ditto evenly rounded ; interior por-
cellanous white, the pallial sinus not reaching the middle vertical
line of the shell, broad and rather rounded; ligamental fosset large,
cuplike; anterior teeth V-shaped, about 22 in number, strong and
prominent; posterior teeth similar, and forming an equally long line
but only 18 in number, the posterior cardinal margin showing a
long narrow impressed area very feebly marked ; length of shell
32; beak from anterior end 12; vertical from beak to base 17;
max. diameter 13 mm.
Habitat U.S. Fish Com. Station, 3202, in 382 fathoms green
mud, Monterey Bay, California, bottom temperature, 41° Fahren-
heit.
This fine shell recalls Y. thracieformis, but is smaller, without the
angularity of that species and proportionately more solid. It was
dredged by the U. S. Steamer Albatross, several years ago. It is
probably a deep water species exclusively at least in the latitude of
California. The types are in the U.S. Nat. Museum, 106,972.
NOTES ON THE GENERA OF UNIONIDZ AND MUTELIDZE.
BY H. A. BRESBEY.
In the June number, p. 20, a list of the genera of Unionide and
Mutelide recognized by Dr. v. Ihering is given. It should be noted
that by inadvertence Pleiodon Conr. is given as a genus, but Iher-
ing considers it a synonym of Jridina. The genus Pseudodon Gld.
was omitted after Cristaria Schum."
Attention should also be directed to the fact that the name Cas-
talia Lam., 1819, is preoccupied in Vermes by Savigny, 1817 (Sys-
téme des Annelides). Probably TerraPpLopon Spix, 1827 can be
_used in this case as a substitute.
For Aplodon Spix (preoc. by Rafinesque in Pulmonata), may be
substituted SprxoconcHa.
Lea’s name Plagiodon (1856) seems also to be preoccupied (by
Dumeril in Reptilia, 1853), and the group may therefore be called
IHERINGELLA, Lea’s species isocardioides being the type.
1The Editor fears that these errors may have been due to his own hasty proof-
reading, rather than to defects in the original MS.
THE NAUTILUS. 31
NOTES ON THE ACANTHOCHITIDZ WITH DESCRIPTIONS OF NEW
AMERICAN SPECIES.
BY HENRY A. PILSBRY.
The family Acanthochitide includes Chitons having the exposed
surface of the valves, when present, divided into a narrow dorsal
smooth or striated band, sometimes obsolete, with a granular area on
each side, formed by the union of the lateral areas and the plural tracts
of the central areas. The Cryptoplacide also share this peculiar plan
of valve-sculpture, but they are vermiform in shape and not nearly
covered above by the valves, whilst the Acanthochitide have well-
developed valves covering the upper surface, even in those genera
like Amicula and Cryptochiton which have the girdle-skin extend-
ing over the larger part or the whole of the dorsal armor. There
are many other differences, but still the Cryptoplacide give unmis-
takable evidence of their descent from Acanthochitide. On the
other hand, all other Chitons differ in having the valves divided into
triangular lateral, and wide central areas, and in other equally
important if less obvious features.
_ The following genera belong to Acanthochitide : Spongiochiton,
Leptoplax, Acanthochites, Katharina, Amicula, Cryptochiton. All
but the first two are found upon the United States coasts. It will
be noticed that the association of Acanthochites with Mopalia, insti-
tuted by Dr. Philip Carpenter, is not retained.
Some naturalists may find it difficult to believe that complex
structures so very similar to each other as are the posterior valves in
Mopalia and Acanthochites could have arisen independently; but
that this is the fact I feel entirely assured. In the two cases, this
peculiar form of two-slit and sinused posterior insertion-plate, arose
from a perfectly regular, even, and many-slit plate; the two phyla
travelling along parallel roads. The Mopaloids reach their culmi-
nation in Plaxiphora, which has lost its two posterior slits, and is in
this respect quite analogous to an old individual of Cryptochiton
stellert. |
The genus Acanthochites, which has given its name to the family,
is readily recognized by the series of tufts of fine bristles, like spun-
glass, along each side. These tufts may be accounted for by the
theory that they are the result of over-nutrition caused by the fre-
quent flexure of the girdle at the sutures; this flexure naturally
bringing a greater share of nutriment to the stimulated point than
32 THE NAUTILUS.
to the comparatively motionless portion at the sides of each valve,
resulting in a more exuberant growth of girdle spicules there.
Within the Acanthochites stock the progressive diminution of the
tegmentum or outer layer of shell, has proceeded along two lines:
in one series of forms the girdle has encroached at the sutures, pro-
ducing a heart-shaped exposed area, seen in such species as the Noto-
places, and this system has also produced the Amiculas. In the others,
the tendency has beén to encroach along the sides of the valves, leay-
ing a narrow or linear tract, resulting in forms like Acanthochites
exquisitus, and culminating in Cryptoconchus (C. monticularis Q..,
and floridanus Dall.)
Acanthochites is divisible into four sections: Acanthochites typi-
cal, having a wide caudal sinus and two slits in the tail valve, and
well-developed sutural tufts; Notoplax, having several slits in the
tail-valve behind, and the girdle encroaching at the sutures; Cryp-
toconchus, having’ a similar tail-valve, but the girdle encroaches at
the sides, leaving only a linear dorsal area exposed ; and finally,
Loboplax (sect. nov.), with a many-slit tail-valve, the head valve
strongly 5-lobed and ribbed, girdle nearly. naked—type A. violaceus
~ Quoy. The following two species belong to the typical section :
A, exquisitusn.sp. Visible portions of the valves extremely narrow, |
generally less than one-fourth the entire width of the dried animal.
Valves dark olive, interior blue; the girdle light green, tufts very
large, either green, pink or bronze; fleshy covered with a green
pubescence. Length 30, breadth 18 mill. La Paz (Lockington).
The valves are more covered than in any other form, the tegmen-
tum being far less in area than one of the sutural laminz.
A. rhodeus n. sp. Exposed portion of valves subtriangular, about
one-third the entire width, the valves depressed, obtusely carinated,
brown, almost separated by the encroachment of the girdle at the
sutures. Median area smooth, not striated. Interior deep rose
-colored. Length 28, breadth 15 mill. Panama (MacNeil).
A. (Notoplax) hemphilli n. sp. Valves heart-shaped, about one-
third the total width; red, more or less maculated with white;
girdle rust-brown; dorsal area having some longitudinal strie. .
Interior light green at the sides, deep rose-red in the middle. Girdle
wide, sparsely clothed with microscopic hyaline spicules, having a
marginal row of longer spicules and 18 small white tufts. Length
24, breadth 11 mill. Key West, Florida (Hemphill).

NOTE ON ENDODONTA (Flammulina) INFUNDIBULUM Hombr. & Jacq.
BY CHARLES HEDLEY, AUSTRALIAN MUSEUM, SIDNEY, N.S. WALES.
In the “ Reference List of the Land and Fresh-water Mollusca of
New Zealand” by Mr. H. Suter and myself, the species named above
was placed under Flammulina crebriflammis Pfr. as a synonym.
Tryon and Pfeiffer, whom we followed in this course, were certainly
wrong in connecting infundibulum with crebriflammis (Mon. Hel.
Viv. iii, p. 148, etc.). HZ. infundibulum was described from Vavas,
Tonga Is., and-appears to be a small variety of Gradata Gould. It
was omitted from Mousson’s Tongan list.

NOTICE OF NEW CRETACEOUS FOSSILS FROM THE LOWER GREEN
MARLS OF NEW JERSEY:!
BY R. P. WHITFIELD, AMERICAN MUSEUM OF NATURAL
HISTORY, NEW YORK CITY.
Mr. Pilsbry recently sent me a few New Jersey fossils for identi-
fication ; among them were the following new species which he wished
me to describe for the NAuTILUus.
Volutoderma Woolmani n. sp.
Shell, as shown by the internal cast, somewhat more than an
inch in length, and having a diameter of the body volution of seven-
sixteenth of an inch in the cast, being more slender than any species
yet described. Volutions largest just below the suture and attenuate
below, forming a moderately long beak; marked in the upper part
by eight comparatively strong vertical plications, which are obsolete
below. Columella marked by three very distinct folds or ridges, the
lowest of which is the strongest. These are well marked on the
inside of the upper volutions. |
This species like most of those from the New Jersey Green Marls
is known only from an internal cast. It retains only two volutions
and is imperfect at the base of the beak. It is very distinct, how-

ever from any species previously noticed, being much smaller and
of more slender habit. The external markings are unknown. The
specimen is from the Lower Green Marls at Lenola Station on the
Long Branch Division, Pennsylvania Railroad in Burlington Co.,
New Jersey. The type is in the collection of the Academy of
Natural Sciences of Philadelphia. Collected by Mr. Lewis Woolman
of Philadelphia for whom it is named.
Cerithium Pilsbryi n. sp.
Shell elongated and slender; volutions numerous, number not
determined, very gradually expanding with additional growth;
apex and aperture unknown. Volutions slightly convex between
sutures, and ornamented by a band of small oblique nodes immedi-
ately below the suture ; also by a series of larger vertical folds which
extend across the exposed part of the volution, below the upper band
of nodes, and numbering something more than one half as many to
the volution as the nodes above. There are also very fine spiral
striz almost too fine be seen without magnifying. The lines of
growth are fine but distinct, and take a broad sweeping backward
curve between sutures. Apical angle fifteen to eighteen degrees.
This species is a new type for the New Jersey cretaceous, and I
know of none of the same type in the rocks of this age in North
America; while in the Cretaceous of Palestine there are several
species already described. The one most nearly like this being that
described in the Bulletin Am. Mus. Nat. Hist. for December, 1891,
figured on PI. IX of Vol. III, figs. 11 and 12, under the name
Cerithium Conradi ; the point of difference between them being the
exact reversal of the lines of nodes, the upper one here being small
while on that one it is the largest. These specimens consist of concre-
tionary matrices, in what appear to have been Coprolitic bodies, in
one of which there are fragments of several species of molluscs repre-
sented. They are also from the Lower Green Marls at Lenola, N. J.
Collected by Mr. Lewis Woolman, and are deposited in the collec-
tion of the Academy of Natural Sciences, Philadelphia.
Another Cerithium-like shell occurs with the above, but is too
imperfect for specific description. It presents characters which
would most likely ally it to Cerithtopsis. ‘There are imprints of por-
tions of six volutions remaining inthe matrix showing three lines of
nodes on each yolution, increasing in size from above downward.
This also is an undescribed species. There is also an internal cast
of a species of Anchura or Rostellaria, which differs from any
THE NAUTILUS. 39
described form, but too imperfect for characterization. Mr. Wool-
man writes me that the locality from which these specimens were
obtained has yielded upward of sixty species of Molluscan remains,
which is rather more than that obtained from any one locality
within the State, from this bed, so far as I know.
DESCRIPTION OF A NEW SPECIES OF CYPRAEA.
BY JOHN FORD.
In the description of Cyprea cruenta Gmel. var. Greegori Ford,
published in the Nauritus for Feb., 1893, it was suggested that most
conchological students would probaby have made G'reegori a species
instead of a variety. It may at once be said that the writer of that
description is now fully convinced of the specific distinction of the |
latter, and has therefore decided to alter the name from C. cruenta
Greegori Ford to C. Greegori Ford. Under the circumstances such a
change will doubtless meet with some opposition. Nevertheless, I
have no hesitation in making it, inasmuch as my conclusions are
chiefly based upon the careful study of some fifty specimens secured
by me since the description referred to was written.
These are of various sizes and stages of growth, yet all of them
can be readily separated from any other species belonging to the
genus, though in exceptional instances the heavy callus on the sides
and ends is creamy white and the typical blotches scarcely discern-
able. The larger portion of my former description may be profit-
ably retained, but as it is desirable to make a few additions it is
reproduced here with these included.
40 THE NAUTILUS.
Cyprea Greegori Ford, n. sp.
Shell depressed, orbicular oval in form, callus on the sides and
ends remarkably thickened. That on the sides light salmon in color,
with irregular purple-brown spots, having a blotchy appearance.
Dorsal surface similar to that of cruenta, but lacking the whitish
spots typically present in that species. Base semi-translucent, spot-
less, dark buff or salmon colored, darkest in the interstices. Teeth
on outer lip very strong, long and whitish ; on inner lip finer, with
exception of the anterior fold and one or two adjacent teeth, the first
of these latter being very prominent and notably transverse. Space
between the anterior fold and the following tooth wide and bright-
ened ; posterior teeth of inner lip prolonged outward upon the base.
Dimensions of average specimen: length 14, breadth ¢ inch.
That C. Greegori is more nearly related to C. cruenta than to any
other species, I have no doubt. But it is equally true that the
former possesses several characters altogether distinct from those
belonging to the latter. For instance, C. greegori is more translu-
cent, more rugged, much smaller and rounder in form, different in
general color, and in the peculiar variations of the teeth, also in the ©
remarkable thickness and brilliancy of the callus with which it is
rimmed.
With the probable exception of one poor specimen, this shell was
unknown to the late Mr. Tryon, and for the same reason, perhaps, —
it was not noticed in Mr. Robert’s catalogue of the species. Never-
theless, an excellent figure of it was published by Kiener' who merely
referred to it as a variety of C. cruenta (variolaria). A figure,
possibly intended for the same shell, was also published by Sowerby’
who seems to have considered it a variety of C. caurica. More
recently, Sowerby’s figures were alluded to by Mr. J. C. Melvill’, as
the var. coloba, but whether this variety was referable to C. cruenta
or C. caurica, seems to have been a question that he was either unable
or unwilling to decide. At least, in one sentence he apparently
makes C. cruenta responsible for its parentage, while in another
sentence the same honor is given to C. cauriva. Verily it seems that
even the babes in “ Pinafore” could not have been more hopelessly
mixed than were these poor little .waifs.

THE NAUTILUS. 41
So far as I am aware, no description of the shell, previous to my
own, has been published ; and unless proof of such publication is
shown I shall claim priority both for the name and description.
This claim has especial reference to a criticism of the name applied
to the shell in my former articie.
It might be well to add that the incipient tooth in the interstice
next to the anterior fold, as shown in the figure published in THE
Nautiuus for April, 1893—is not typical, since it is discernable in
less than five per cent of the specimens, and very slightly in them.
In a hurried selection of the specimen for drawing purposes, this
very minute protuberance was unobserved by me. Otherwise it
would not have been drawn. This error has been corrected in the
figure accompanying this article. |
BEACH SHELL COLLECTING IN CONNECTION WITH A STUDY OF
OCEANIC PHENOMENA.
BY MRS. M. BURTON WILLIAMSON.
_ It has often occurred to me that a shell collector who is something
of a physicist, having a love for historical facts, could furnish
interesting data in regard to shore collecting under certain physical
conditions of the ocean. Few amateur collectors note the historical,
or rather chronological appearance of genera and species collected
by them, they are usually satisfied with obtaining a “good find,”
but time and seasons are hardly observed, certainly not studied as
furnishing data for future reference. A storm is hailed as a precur-
sor of “ rare finds,” but a study of the storm with notes in regard to
it, accompanied with a list of shells found after such a storm are too
frequently neglected by collectors. Mollusks are collected too often
as a miser collects his money, as a mania, not as a medium for an
. intelligent study of Nature. It seems to me, that a study of
mollusks thrown upon the shore from other areas, in connection with
a study of the physical condition of the ocean at such times, would
be very helpful to the collector, although of no value to science. It
may be urged that shells cast up by the sea are merely “ happen-
42 THE NAUTILUS.
ings” and no data can be gathered in reference to what seems a work
of chance. When a heavy gale ploughs up the home of mollusks
and huge breakers land them, by the incoming tide, on the shore, no
collector can fore-tell when such a phenomenon may occur, nor
what conchological rarities may follow in the wake of such a storm.
Rare shells are sometimes washed ashore, then years may elapse
before they again make their appearance. Sometimes shells con-
sidered as belonging to the fauna of a different latitude are found
among the drift in such small numbers as to raise a question as to
their introduction by artificial means. During a violent storm
mollusks travel great distances before they are cast upon the shore.
This is especially noticeable in pelagic organisms which are often
cast upon the beach when some ocean current buoys them inward
toward the shore. All these facts combine to make it impossible
to collect working data, but one cannot doubt that a study of collec-
tions as the result of unusual conditions of Neptune might be con-
ducted with some satisfactory results. A diary of the atmosphere,
tides, daily physical conditions of the ocean with lists of shells found
during the same period, if followed any length of time, might be
resultant in adding a few facts that would be interesting, even
though not very valuable. High and low tides would influence
“finds” atany time, but some “low tides” are much richer in
molluscan forms than others.
As a rule each region has its own fauna; when this fauna is dis-
turbed and carried outside the range of its own normal environment
it must be due to unusual conditions in the surrounding water ;
shells from the laminarian and inner corallines zones found strewn
upon the beach are the effect of some cause. To a physicist, a study
of the storm that stranded rare forms upon the beach, would surely
be as interesting and important as the shells found in the drift!
The study of oceanic phenomena in connection with conchological
acquisitions might be valuable to the collector in many ways;
although of no value to the scientific world in these days of applied
science, with hydrographers collecting data, and with all the modern
appliances furnished to ships sent out on scientific explorations.
We narrow our horizon by failing to observe and study that which
is near at hand. There are environments that afford more than
ordinary facilities for study, but only a few are so favored, and only
a small proportion of these utilize their opportunities.

NOTES ON THE NORTH AMERICAN SPECIES OF SUCCINEA.
BY T. D. A. COCKERELL.
[ Concluded from Vol. VI, p. 31.]
(18.) S. luteola Gould. Mr. Singley sent me this from Manatee Co.,
Florida, and at the same time specimens marked tewvasiana
Pfr., from Derby, Frio Co., Texas. I made notes on these
shells as follows:
(a.) S. texasiana. Belongs perhaps to putris group, but very
different from it, and forming a new subsection. Shell
shaped, but for mouth, like some varieties of Limnea
palustris. Length 163 mill. Transversely irregularly
striate-ribbed. Young example semitransparent pale
horn, adults opaque yellowish-white.
(b.) S. luteola. No doubt the same species as texasiana, but the
specimens are horn-color and smaller; some little ones are
more like putris—7+ mill. long, shiny, striate, horn-color,
more globose, spire short.
Sect. IIL. Lucene.
=Tucena Oken.
(19.) S. avara Say. This species varies in color a good deal, and
also in shape. The following are the varieties described or
known to me.
(a.) forma alba noy. Shell greenish-white. Horseshoe Bend
Gulch, Custer Co., Colorado, at about 10,000 ft. alt. Mr-
H. Prime has an albino of S. avara from Arizona, and
there is a specimen in the Binney and Bland collection
from New York State (Dr. Lewis.)
(b.) forma wardiana Lea. Shell yellow.
(c.) var. vermeta Say. Yellowish, thin, suture deep. I have
seen a clear red-brown form of this from Toronto, Can-
ada (D. B. Cockerell). An amber-colored form was sent
to me by Mr. Binney, collected by Mr. W.S. Teator at
Barrytown, Duchess Co., N. Y.—this may also fall
under vermeta.
44
THE NAUTILUS.
(d.) var. compacta Ckll. J. of Conch., 1892, p. 39. Colorado.
(e.) forma major W.G. Binney, Ac. Nat. Sci. Phila., Nov.,
1858, sine descr. A large variety, about 134 mill. long,
in the Binney and Bland collection, is from Utica, N.
Y. It is marked var. major, apparently in Mr. Binney’s
handwriting.
(20.) S. aurea Lea. I formerly supposed this might be
closely allied to pfeifferi; having received a close relative
or variety of that species from St. Thomas, Ontario, Can-
ada (D. B. Cockerell), which seemed to agree with aurea.
This view, however, was probably erroneous, as a speci-
men marked aurea in the Binney and Bland collection
seems to belong to the avara section.
(21.) S. mooresiana Lea. I have found shells in a dry locality
on Round Mountain, Custer Co., Colo., which, although
no doubt referable to a variety of avara, appear to be
Lea’s mooresiana. A specimen of mooresiana in the
Binney and Bland collection, from the Platte River, also
seems to belong to S. avara.
(22.) S. oregonensis Lea. Mr. Singley sent me this from Dal-
les, Oregon, (EK. H. White). I noted that they were of
the avara group, but in shape approaching the pfeifferi
group, pale reddish-horn, striate, dull. One in the Bin-
ney and Bland collection looks like a member of the
pfeiffert group, but another, marked with a query, is
larger and seems to belong to the avara section.
(23.) S. rusticana Gould. Mr. Singley sent me some shells
labelled oregonensis from Plumas Co., California (G. W.
Michael), of which I noted: avara group, larger than
oregonensis from The Dalles, greenish-horn, more shiny,
whorls more convex. These specimens seemed to agree
better with rusticana than oregonensis. Later, Mr. Bin-
ney has sent me a shell, apparently rusticana, found by
Mr. Hemphill at Julian City, San Diego Co., California.
This shell is 10% mill. long, form of rusticana, but aper-
ture more oblique, color reddish-horn, rather shiny ; soft
parts (in alcohol) black. It is impossible to tell whether
on Z
— eee S|, eee
a -
THE NAUTILUS. 45
these shells should be separated from rusticana without
examining a larger series showing the variation.
(24.) S. verrilli Bld. Apparently belongs to sect. Lucene, but
I have not seen specimens.
(25.) 8. grenlandica Beck. Specimens in the Binney and
Bland collection from Kuksuk, Greenland, almost cer-
tainly belong to this group; although the species seems
to have leaning toward the Campestres, with which it
allies itself through S. chrysis and S. annexa.
Section IV. Campestres.
(26.) S. campestris Say. Mr. Singley sent me specimens of this
from Long Key, Florida; they seemed to me nearly identi-
eal with S. lineata from Kremmling, Colo. A variety of
campestris was named inflata by Lea.
(27.) S. lineata W.G. Binney. Found in rejectamenta at Kremm-
ling, Colo., together with a form elongata, Ckll., J. of Conch.,
1892, p. 39.
(28.) S. greeriti Tryon. This is considered asynonym of S. obliqua,
but a dead shell in the Binney and Bland collection from
Vicksburg, Miss. (Tryon), appeared to resemble campestris.
(29.) S. chrysis Westerl.
(30.) S. annexa Westerl. This and the last appear to belong here,
but are probably related somewhat to grenlandica. The
presence of whitish streaks on the arctic species is note-
worthy. Dr. von Martens (Conch. Mittheilungen, 1885)
has described a var. aurelia of S. chrysis from Alaska.
(31.) S. unicolor Tryon. A specimen so named is in the Binney
and Bland collection from New Orleans, La. It isa peculiar
shell, apparently of sect. Campestres, very globose, spire short
and blunt.
(32.) S. turgida Westerl. This species is unknown to me; it is
recorded in Land— och Séty. Moll. Vega—Exped. 1885.
(33.) S. decampii Tyron. Belongs to Amphibine, and was acci-
dently omitted in the proper place. It is considered a form
of ovalis, but a specimen from Michigan (Tryon), in the
46 THE NAUTILUS.
Binney and Bland collection seemed hardly quite like
ovalis ; small, shiny, thin, rather greenish.
Of these 33 nominal species of Succinea, possibly not more than
about half will prove valid, but it is impossible to arrive at any
exact results without further research into the variation, anatomy
and distribution of the several forms.
The distribution, so far as known, present some features of
interest. ‘The species of the eastern and northern states are more
like those of Europe than the southern or western. . The southern
and northwestern distribution of the campestres is noteworthy. It
appears that in glacial times, owing to a warm current, the coast of
Alaska was free from ice, while that of British Columbia was
glaciated down to the sea’; hence a contingent of the campestres may
have survived to the north, while their representatives in some of
the middle regions were exterminated.
While on the subject of Succinea, it may be worth while to call
attention to fig. 13 of pl. Il, Bull, U. S. Geol. Survey, No. 34,
(1886). The fossil there figured is referred by Dr. C. A. White
with doubt to Limnea, but is it not a Succinea of the section
Lucene ?
Regarding the Calif. Succ. stretehiana (Naut. VI, p. 72), I fear
the specimens were in a box which unfortunately got lostin the
post on its way back to Mr. Singley. They seemed to represent a
distinct form, but it is possible that they were not true stretchiana.
Bland’s type was from Washoe Co., Nevada; and no doubt the
specimen from that locality in the Binney and Bland collection
belonged to the original lot, the actual type being in U. S. N. M.
(see Man. Amer. Land Shells, p. 497). The Washoe Co. specimen
examined by me was in some respects like avara, and by no means
altogether like the Californian examples; but considering the
variation seen in species of Succinea, I did not feel able to decide
without better material, whether they should be held distinct, and
so accepted the indication of the labels. There is a Colorado Succi-
nea which was formerly thought to be stretchiana, but it is certainly
either a var. of avara or a species very closely allied. Is anyone
prepared to say exactly what distinguishes stretchiana from other
species? Ifthe San Francisco specimens were not stretchiana, I am
rather puzzled to know what are the true characters of the species.
Perhaps the anatomy would settle the question.

GENERAL NOTES.
VITRINA LIMPIDA IN PENNsyLVANIA.—In April of this year I
found about a dozen dead shells of Vitrina limpida Gould on the
bank of the Ohio River about 14 miles below Pittsburg, I have
since visited the place and found about 20 additional shells all dead
and most of them broken. There were many more too badly broken
to be worth taking. A careful search both times failed to bring
any live shells to light, and as many of the shells found were young
I think the colony must have become extinct last year. They were
found among “ drift,” so may have come from the head-waters of
the Allegheny River in New York State.
I intend visiting the place again soon and will report results—
Geo. H. Clapp, Pittsburg, Pa.
ARGONAUTA FOUND ALIve.—A living specimen of the Paper Nau-
tilus, Argonauta argo, was found at Palm Beach, Dade Co., Fla., in
April by Mrs. C. Rowland of Philadelphia. This handsome shell
is over six inches in diameter. It is rare that living examples of
this are found on our coast.
The West American Scientist for July contains a biographical
sketch of the late Henry Chandier Orcutt, of San Diego, Cal.
A Rare Ovp Boox.—An auction sale of old and rare books took
place here a few days ago. This collection was consigned to
a prominent auctioneer direct from Great Britain (around the
Horn). I was lucky enough to have a catalogue sent me. In look-
ing same over, I found only one book on Conchology. It was
numbered 324 and described as “Collection de differentes especes
de Coquillage, par George Wolffgang Knorr. Both parts, plates
giving hundreds of beautifully colored figures of rare shells, 4to”
I attended the sale and when no. 324 was put up the bid started
at 50 cents; I went one better, 55, then two prominent bookdealers
began bidding with me, until one of them struck the dollar limit
and ceased. I went one better, bidding $1.10; and as they saw that
I was determined to get it, they stopped ; and the book was knocked
down to me for the above ridiculously small amount.
Upon reaching home I found it to be published in French, and
during the reign of King Louis XV—1765, although George
48 THE NAUTILUS.
Wolffgang Knorr, the author, states he wrote it during Nov. 1756
at Nuremberg. The print isin the old style; very large.
The book contains 100 pages, has 47 plates containing 248 exqui-
sitely water-colored (by hand) figures of shells.
Think of the time it must have taken to color these! How I
would like to have a glimpse of the person who colored them, 129
years ago! Some of the tints, especially the pearly ones used in
Haliotis striata, Haliotis marmorata and Trochus niloticus, are
something wonderfully clever.
On the inside of the cover, was a piece of paper glued. On it
was engraved a crest of some person, with the words “ Navitir et
Solerter,” and underneath it was engraved the following :—“ Daniel
Cresswell, S. T. P. Coll: S.S. Trin: apud Cant: Soc.” The crest
was composed of a large ostrich with a nail in its mouth. Beneath
this was a shield, within same were three squirrels sitting on their
hind legs, eating acorns or something of that sort. Upon close
investigation, I discovered this crest was pasted over another.
With a great deal of trouble I succeeded in separating the two.
The lower one was an egg-shaped circle, within was a shield with
three holes in the upper portion. On top of the shield rested some
kind of a royal head-gear. Upon this head-gear lay a mummy
and upon the mummy an eagle had just alighted, and was in the act
of tearing out the eyes of the mummy. Under the crest was the sig-
nature of “JOHN LATHAM, M. D., Winchester. ”
Who can tell me anything about the persons above named?
Also if there are many of these books in existence. I should judge
they were quite rare. How I do wish that many other British col-
lections of old books might be brought here and sold at pub-
lic auction. Many rare books published during 1567-1656-1780
and 1800 were sold at the above sale, all the way from 25 cents to
$5.00— Williard M. Wood, San Francisco, Cal., March 15, 1898.

DESCRIPTION OF A NEW FOSSIL CYPREA.
BY JOHN H. CAMPBELL.
Cyprea Squyerin.s. Plate IJ, figs. 1, 2.
Shell ovate-oblong, attenuated at the extremities. Spire promi-
nent, showing four whorls; outer lip thickened and having on the
inner edge thirteen or fourteen teeth. Anterior half of the aper-
ture wide, but contracted at the extremity, posterior end contracted
and projecting slightly beyond the spire. Under the magnifying
glass the shell shows strong revolving raised lines and strie.
Length 20 mm., width 11 mm., height 9 mm.
A notice of the finding of this shell by Mr. Homer Squyer of
Mingusville, Mont., in the cretaceous formation (Fox Hills Group)
of eastern Montana, and the above proposed name, were published
in the Nautriius Vol. VI, p. 50. This shell resembles in outline
the recent Cypreea stolida, but its very prominent spire would sepa-
rateitfrom this group. Shell structure is wanting on most of its dor-
sal surface and the inner lip obscured by the hard matrix, which it
would be inadvisable to remove. In a recent letter from Mr.
Squyer he says “ This-ssummer while looking for fossils I found the
outer lip of the imperfect specimen, found at the time I obtained
the type. This specimen I have sent to the U. S. National
Museum.” The type has been placed in the collection of the
American Association of Conchologists.

Duncan, Indefatigable, and Barrington Islands, Dr. Baur.
This shell is closely related to B. jacobi and was figured by
Reeve under the name of jacobi. The original jacobi was sent by
Cuming to Dr. Lea and subsequently a specimen of Reeve’s form
was added by Mr. Cuming. ‘These are now in the Nat. Museum.
The true jacobi is smaller, and is sharply spirally sculptured with
fine lines of beaded granules alternating in size, every fifth or sixth
row being larger. It has six inflated whorls and a pale peripheral
band. JB. olla has a nearly smooth almost polished surface, only
marked with incremental faint lines, seven whorls and a very bul-
bous pillar. It is a larger shell than the original jacobi. The lat-
ter comes from James, Albemarle, Charles and Chatham Islands, in
the wooded zone, while B. ol/a inhabits the grassy upper zone.

Bulimulus (Nesiotus) tortuganus n. s.
Shell small, solid, moderately elongated with six and a half
whorls ; the earlier whorls subtranslucent madder brown with a pale
peripheral stripe, more or less silky and sculptured with very fine
spiral lines ;, sutures very distinct ; later whorls malleated, wrinkled
or pecked; rude, fleshy white, with a variably large perforate
umbilicus ; aperture small, with a lump on the pillar and another
within the middle of the outer lip; lips thickened, white, slightly
reflected, the throat brownish, body with a thin, transparent callus.
Lon. of shell 12, of aperture 5-5; max. diam. of shell 7 mm.
La Tortuga, grassy zone, South Albermale, Baur.
This shell which is very characteristic seems to be abundant
where found by Dr. Baur. Itseems nearest to B. simrothi Reibisch.
of the described species. It is remarkable for the illustrations it
gives of the varied influence of the environment on different individ-
uals. The sculpture of the last whorl recalls that of B. rugiferus.
The young is hispid and colored like that of wnifasciatus, but is
narrower; the pale peripheral band is almost wholly obscured in
the adult and the hairs are soon lost.
Bulimulus (Nesiotus) Bauri n. s.
Shell small, short, stout, with a dark rapidly attenuated spire,
distinct suture, and opaque yellow-brown last whorl ; whorls about
seven, the earlier ones dark livid purple with straw colored streaks,
paler at the suture, rude and malleated ; last whorl inflated, more
or less transversely wrinkled, somewhat polished ; umbilicus closed
or a mere chink; aperture subquadrate, angulated behind and at
the base of the pillar; pillar short, oblique; lips simple, thick,
especially across the body where the callus has a raised edge ; throat
white. Lon. of shell 10, of aperture 45; max. lat. of shell 6°5
mm.
Hibernating on the under side of leaves of plants at the Southwest
end of Chatham Island, 1600 ft. above the sea, Dr. Baur.
This is one of the most distinctive species of the whole group.
Hyalinia chathamensis n. s.
Shell small, thin, straw colored, depressed, with four rounded
polished whorls ; suture distinct; sculpture of numerous radiating,
slightly flexuous, indented lines; umbilicus deep, exhibiting all the
volutions, but rather narrow. Max. diam. 3, min. diam..2°25 mm.
Alt. of shell 1°30 mm.
PON Ea

Chatham Island, 1600 feet, 1 specimen, Dr. Baur.
This shell recalls H. arborea Say, but is much smaller and has a
different umbilicus. In the characters of the aperture, etc., not
mentioned above, it duplicates arborea.
oO
Conulus galapaganus n. s.
Shell close to C. fulvus, but has five whorls to four in a specimen
of fulvus of the same diameter; it has a very well marked suture
and the whorls between the sutures are more rounded than in
fulvus. The height of C. galapaganus is greater in proportion to
the number of whorls. Alt. of shell 3°25; max. diam. of shell 2°5
mm.
Chatham Island, 1600 ft., Dr. Baur.
This shell appears to differ from all the forms like fulvus, selenkat,
ceecocides, etc., by its smaller size, very brilliant surface, inflated
whorls and number of turns. It wants entirely the spiral striation
of Zonites bauri which is a much larger and more depressed shell.
In fact it seems like an elevated, dwarfed and inflated C. fulvus.
There are probably other Helices on the islands which have not
yet been collected.
Succinea corbis n. s.
Shell small, of two and a half whorls, to which a black mould
adheres with tenacity. The first whorl and a half are salmon pink
in the adult but the young of the same size are pale amber. In the
adult the last whorl is of a pale straw color. The shell resembles
S. wolfi in form but is smaller and has a more contracted aperture ;
it is instantly recognized, when examined with a good lens, by its
surface which is minutely shagreened all over with an excessively
fine network of closely recticulated incised lines. Alt. of shell 4.,
max. diam. 4; extreme length of aperture 4 mm.
S. Albemarle Island on dry bones of turtles, Dr. Baur.
The remarkable sculpture is not visible to the naked eye except
as a sort of hoary bloom on the surface. Under a compound
microscope it looks like closely woven basket work. I have exam-
ined a great many Succineas without finding any other species pos-
sessing this character. The sparse dichotomous impressed sculpture
which appears on Succineas from Samoa and other oceanic islands
and is occasionally visible on S. bettii is an entirely different
thing.
56 THE NAUTILUS.
I may add that the S. bettit var. brevior of Smith, is in my opinion
distinct from S. bettii and should he raised as S. brevoir to specific
rank. JI have examined a large number of both forms. S. bettii is
a species of the wooded zone, S. brevior of the dry zone. It is prob-
able that S. wolfi Reibisch may be only a variety of S. bettit.
The final report on Dr. Baur’s collections will not long be delayed.
The species will be figured and their anatomical characters dis-
cussed. The most important fact thus far determined is the close
alliance of all the Nesiotes, Rhaphiellus and Pleuropyrgus to the
American Bulimuli of the type of B. serperastrus. The different
forms of the shell are dynamic not genetic differences, and there is
no doubt as to the exclusively American type of the whole fauna,
when the groups represented are not of world wide distribution.
PRELIMINARY NOTE ON THE SPECIES OF STROBILOPS.!
BY H. A. PILSBRY.
The United States species of this genus have generally been
believed to be but two in number, the “ Helix” labyrinthica of Say,
and Hubbardi of A. D. Brown; the types of both being in the
museum of the Academy of Natural Sciences of Philadelphia.
The writer some months ago, gave the varietal name virgo to
specimens sent him for determination by Rev. H. W. Winkley,’ and
later the name affinis’ to another form.
Recently, with the assistance of Mr. H. E. Sargent, the various
species and varieties have been re-examined and compared, with the
result of finding that, in what has;hitherto passed as “ H. labyrin-
thica,” there seem to be at least three well marked species. . These
species agree in general form and sculpturing, but differ in size,
color, degree of depression, and especially in the internal lamelle of

basal and outer walls of the body whorl. In this they are compara-
ble to the Clausilias, Endodontas, ete.
The species may be tabulated thus:
a. Internal lamelle on floor of body whorl 2 or 3, short; color dark
brown ; one parietal fold conspicuously emerging from aperture.
b. Form elévated conoidal . . . S. labyrinthica Say.
bb. Form much depressed . . 8. labyrinthica strebeli Pfr.
aa. Internal lamelle on floor and adjacent side wall of body whorl
6 or more.
6. 6 long lamelle ; 2 parietal foldsemerging; color white or
pale brownish; form elevated, . . S. virgo Pils.
6b. About 8 short lamellz arranged in a curved radial series;
color dark brown; form elevated ... . S. affinis Pils.
The figures of Morse and Binney represent S. labyrinthica Say.
The 8S. labyrinthica strebeli Pfr. was described from Mirador,
Mexico, the specimens before me being from that locality. It was
well figured by Pfeiffer in the Malakozoologischer Blatter viii, pl. 1,
figs. 5-8; but Crosse and Fischer’s figures (Moll. Mex.) do not
represent it. They were probably drawn froma specimen of S.
virgo, but certainly not from strebeli. Mr. Sargent has found a
form closely resembling the Mexican strebeli, at Woodville, Ala.
The original examples of S. virgo are greenish-white in color.
They were collected by Rev. H. W. Winkley near Sebec Lake,
Piscataquis Co., Maine. Mr. Sargent has found a form of the same
species at Woodville, Ala., where they are of a light brownish
tint.
S. affinis isa large form, very abundant at many localities in
New York, Ohio, ete. Its prominent feature is the armature of
numerous short lamella, extending in a forwardly curved series from
the axis across the base and up the side wall.
The writer wishes to prepare an illustrated paper upon these
forms, and will be glad to receive specimens from as many localities
as possible, and especially western and southern localities. Anyone
sending specimens will receive in return (if they wish it) a. copy of
the pamphlet “Preliminary Classification of the Helices,” and,
when it is issued, a copy of the projected paper on Strobilops.
58 THE NAUTILUS.
CHARLES B. FULLER.
BY REV. HENRY W. WINKLEY.
The death of Mr. Charles B. Fuller, which occurred in April
last, removes from our midst a man who had been a most enthusi-
astic worker in the Natural History of the State of Maine. Since
1858 he had been Curator of the museum of the Natural History
Society of Portland, and the results of his labor have greatly
enriched that museum. His interest in Conchology was great, and
though he never published his results, the rooms of the society show
what his labor was. I had several times suggested that he allow
me to send hisname for membership in the Association but his reply
was “I am too old now and cannot help them.” He has however
helped many, and some of our younger members will recall him as
ever ready to assist. Though quiet and retiring, he soon became a
warm friend to one who loved Nature. His work and influence
must live for a long time, though he is no longer present.
THE NEW POSTAL RULING.
It has always been recognized that scientific research is greatly
furthered by the exchange of the various objects with which that
research is concerned. For the transmission of objects of natural
history from one country to another, the mails have offered a cheap
and speedy means. Heretofore, through the laxity with which the
regulations have been enforced, it has been possible to enter such
objects in the mails of the Universal Postal Union as “samples of
merchandise,” and under the rates of postage therefor. From
official information lately received from the United States Post
Office Department, it appears that such a rating is entirely unauthor-
ized by existing provisions, and that objects of natural history may
only be mailed by the rates required for letters. The United
States Post Office Department also stated that it had recently sub-
mitted a proposition to the countries comprised in the Postal Union,
— teh
THE NAUTILUS. 59
to modify the regulations so that such specimens may be entered in
the mails as “samples of merchandise;” but that a sufficient num-
ber of countries had voted against the proposition to defeat it.
Those countries voting negatively were Austria, Bolivia, British
India, Canada, Germany, Great Britain, Guatemala, Hungary,
Japan, Norway, Portugal, Russia, Spain, Sweden, Tunis, Uraguay
and Venezuela.
The Academy of Natural Sciences of Philadelphia has appointed,
through its President, a Committee (Chairman, Mr. P. P. Calvert)
to address the various scientific bodies with which it is in communi-
cation in those countries, and to request them to memorialize their
respective Governments in favor of the proposed modification. The
letter rate for postage in the Postal Union is ten times that required
for samples of merchandise, so that the former is virtually prohib-
itive.
In view of the fact that the subject is one which concerns all
Zoologists, the NauTILUs would urge its readers to use such influ-
ence as they may be able in favor of the proposed change. Foreign
Conchologists living in the countries named above, will, it is hoped,
exert their influence toward the modification desired.
NOTES AND NEWS.
Mr. E. W. Roper of Revere, Mass., returning from Chicago,
visited the Conchological fraternity of Washington and Phila-
delphia recently.
Dr. B. SHarp of the Academy of Natural Sciences of Phila-
delphia has departed on a scientific mission to the Sandwich Islands,
He expects to return in December.
A VALUABLE MONOGRAPH upon the “ Pleistocene History of
Northeastern Iowa,” by W. J. M’Gee appears in the Eleventh
Annual Report of the U. S. Geological Survey, just issued.
The senior Editor of the NAUuTILUs is engaged upon a guide of
the Heliciform land snails. All of the genera and subgenera will
be thoroughly defined, both as to shells and anatomy ; a number of
species of every subdivision will be figured, the anatomy will be
figured, and the species of each group will be enumerated. An

immense amount of new information, not to be found in any of the
conchological manuals, will be offered. The work, it is believed,
will form a complete text book of the subject, and will be indis-
pensable to the student of land snails.
Pror. Rautpa Tare describes a number of interesting new
Australian gastropoda in the Tr. Roy. Soc. S. Austr. June, 1893.
Among them are the following Turbinide and Trochide ; Astralium
rutidoloma, Clanculus consobrinus, euchelioides, Thalotia neglecta,
Calliostoma spinulosum, Euchelus fenestratus, pumilio, vizumbilicatus,
annectans, and E. (Hybochelus) ampullus. He states that Huchelus
tasmanicus Tenison-Woods is the same as E. scabriusculus (Angas)
Fischer, the type of Pilsbry’s subgenus Herpetopoma. A supple-
mental list of S. Australian mollusca is also given.
OLFACTORY ORGANS OF Hexrix. Dr. A. B. Griffiths (Proc. Roy.
Soc. Edinb. 1892,) contends that Sochaczewer’s experiments, by
which he showed that the tentacula of Helix pomatia are not —
olfactory organs, were untrustworthy from his use of turpentine,
which gives off a vapor that is irritating to the sensitive tissues
generally. If snails are placed on flat slabs, the edges of which
have been smeared with eau de cologne, methyl or ethyl acetate,
liquids the vapors of which are not irritants, such as have the
tentacula removed gradually approach the edges of the slabs, while
those whose tentacles are uninjured turn away from the edges. He
concludes, therefore, that the tentacles are the seat of the olfactory
organs in Helix.
The Mid-August number of the Zoologischer Anzeiger contains an
excellent portrait of J. Victor Carus, in commemoration of his
seventieth birthday.
Mr. A. Belt, in writing of the mollusks of Dorset, (England)
gives the following interesting notes. It is well known that thrushes
in seasons of scarcity hunt for snails, and to extract the animal
break the shell by beating it against a stone. Stones that have
been used for this purpose, with the broken shells lying around
them are frequently noticed but I had never before found them in
such profusion as on the present occasion. A very large proportion
of the 576 specimens of Helix nemoralis and H. hortensis found
consist of these fragments. In fact, the birds had so thoroughly
worked the district that until a heavy fall of rain induced the snails
to come forth from inmost hiding-places, I did not find more than a
dozen live shells of these species. On one occasion I found 42
H. aspersa, H. hortensis and H. nemoralis round one stone.

oe NAUTILUS.
VOL. vu. OCTOBER, 1898. No. 6
ILLUSTRATIONS OF MEXICAN MELANIANS.!
BY H. A. PELSBRY.
The distribution of the Melanians and of land operculates in the
Americas forms a most interesting chapter in zoogeography. As is
well known, the family Plewroceride comprises all of the Melanians
found living in North America above the Rio Grande; and more-
over no members of this family or subfamily are known to exist out-
side of this area. South of the Texas boundary there are few mela-
nians or none throughout northern Mexico; but as we approach the
isthmus of Tehauntepec the characteristic neotropical genera Pachy-
chilus and Hemisinus appear, and are represented by a considerable
number of species and innumerable local races. The richness of
this fauna in varietal forms rivals the prolific streams of Tennessee
and northern Alabama. Every spring and stream has its peculiar
variations, often so distinct typically, that the naturalist is tempted
into extravagance in naming them as species. The illustrations here
with given represent some of the forms of Pachychilus glaphyrus
from the State of Tabasco, sent to the Academy of Sciences by
Professor Rovrrosa, a zealous and enlightened naturalist of that
State.

62 THE NAUTILUS.
Pachychilus glaphyrus Morelet.
This species is an exceedingly variable one, more so perhaps than
any other Mexican Melanian. The American student, however,
will readily call to mind cases of equal variability among the species
of our Southern States. The material sent by Prof. Rovirosa com-
prises a number of varietal forms not before made known.
P. glaphyrus Rovirosai Pils. (PI. I, figs. 9, 10.)
Shell large and heavy, elevated conical, the lateral outlines
straight above, modified by the slight convexity of the whorls below.
Spire more or less truncated at tip, half-grown specimens, (PI. I, fig.
9,) possessing 8 remaining whorls ; adults, (PI. I, fig. 10,) having one
or two whorls less.
Surface most minutely spirally striated the striz visible only
under a lens. Young and half-grown specimens are otherwise
smooth, except for very slight spiral lire toward the base. When
a little more than half-grown, there appear coarse, oblique, curved
wave-like folds on the body-whorl, extending to the periphery but
not below it. Simultaneously with these undulations, begin spiral
spaced lirze crossing them, which are slightly more prominent on
the crests of the waves. This sculpture continues upon all subse-
quent volutions. The last volution of an adult specimen is slightly
compressed below the suture, then quite convex. It has ten waves,
and about nine spiral lire, but the number of these last is quite
variable on different specimens.
The color is olive in young, blackish in old examples: interior of
the mouth white, maculated with brown at the position of the
periphery and folds. This marking is also seen on the eroded spire
in some specimens.
Aperture ovate, acute above, slightly exceeding one-third the
total length of the shell. Columella white, regularly arcuate,
spreading in a brown-tinted callus.
Dimensions. An adult specimen measures: Alt. 78, diam. 28
mm. Aperture, alt. 25, width 18 mm. A younger specimen
measures: Alt.56,diam.20mm. Aperture, alt. 20, diam. 123 mm.
Collected from a spring which gushes from the western brow of
the little ridge of the Limon, State of Tabasco, Mexico.
This form is allied to P. glaphyrus typical, and to the var. scam-
nata, but it is distinct from both. The form is notable for its stout,
straight-sided spire, non-impressed sutures, and the unsculptured
young.
THE NAUTILUS. 63
: P. glaphyrus var. between polygonatus andimmanis. (PI. III, figs. 5, 6.)
4 The two specimens figured are of the same size but differ in sculpt-
ure. One (fig. 6) is smooth above and below, having a strong sub-
spinous keel at the periphery, and a smooth, acute keel below it.
Upon the earlier whorls of the spire there are longitudinal waves,
and two spiral cords above the peripheral keel, which diminishes
in size. The base has no spirals. The other specimen has the
entire body-whorl spirally lirate (lire on body-whorl 9, on penulti-
mate whorl 3) and strongly plicate.
P. glaphyrus potamarchus. (PI. ITI, fig. 7.)
This is one of the largest forms of Pachychilus known, and it is
the most aberrant of the glaphyrus stock. The shell is rather
slender and acutely conical, the outline of the spire being straight.
The aperture is ovate, narrowed above, and one-third the length of
the shell. Whorls 10-11 remaining, several of the earlier being
lost by erosion. The microscopic sculpture is the same as in var.
Rovirosat. There are no traces whatever of the waves or folds so
prominently shown by the other varieties of glaphyrus, aud the
spiral cords are also completely obsolete, or indicated by the faintest
traces on the base. The color is olive-green or olive-brown.
Alt. 99, diam. 33 mill.
Alt. 87, diam. 29 milJ.
Tabasco, Mexico.
This variety differs from the pyramidalis of Morelet in being
larger and smoother, lacking altogether the chestnut colored spirals
of that form.
Potamanax subgen. nov.
Shell tela, oval with short conic spire, spirally sculptured or
banded. Aperture ovate, acute above, broadly rounded below ;
-outer lip not sinuous; inner lip more or less heavily calloused, not
notched at the base. Operculum few-whorled, with basal nucleus.
Type P. Rovirosai Pils.
This group has the sculpture of Hemisinus but differs from that
genus in the entire, un-notched basal lip. The columella callus is
much like some species of Pachychilus but the operculum is very
different from that genus. From both of these groups it differs in
the short, ovate contour of the shell. The description of the oper-
culum is taken from Melania brevis d’Orbigny of Cuba, which I
consider congeneric.
The relationship of Potamanax to Hemisinus in sculpture and
operculum is obvious, and has caused me to regard it as an subgenus
ee ee
64 THE NAUTILUS.
rather than a distinct genus; but the total lack of a basal notch or
truncation is a character usually considered of generic importance.
P. Rovirosai n. sp. (PI. ITI, figs. 8, 9.)
Shell oblong-conic, very solid, whitish, encircled by numerous nar-
row smooth spiral lire of a dark brown color, and somewhat
alternating in size. Spire conical, apical whorl eroded; whorls 5
remaining, slightly convex, the last whorl large, regularly convex.
Aperture a little less than half the length of the shell, ovate, angular
above; outer lip regularly acute; inner lip strongly calloused.
Alt. 20, diam. 12 mill: (old specimen.)
Alt. 163, diam. 9? mill. (young specimen.)
Two specimens are before me, collected by Prof. Rovirosa at the
mountains of Poana, State of Tabasco. The older individual (PI.
III, fig. 8) is considerably worn; the other is perfect but not
wholly adult, and neither contains the operculum. ‘The species is
allied, apparently, to the Cuban Melania brevis Orb., but is
decidedly longer, and the liree are much stronger.

NOTE ON CYPREHA GREEGORI FORD.
BY EDGAR A. SMITH.
I sincerely trust that Mr. Ford’ wrongly estimates the critical acu-
men of modern conchological students. He says that most of them
would probably have made C. Greegori a species instead of a variety.
There is no doubt that the new French School of Conchologists
would agree with Mr. Ford in considering the shell in question spe-
cifically distinct from C. cruenta, but I am glad to say that in Eng-
land (and I hope in America also) the ideas are not so advanced (°?).
Although examples of this shell have been in the National collect-
ion for more than 50 years, no British author has ever suggested
that they belonged to a distinct species.
1 NAUTILUS, Vol. vi, p. 112, Vol. vii, p. 39.
THE NAUTILUS. 65
I fully admit that the differences pointed out by the author are
fairly constant, and that examples are pretty easily separable from
the typical form of cruenta. But admitting this does not prove that
they ought to be held specifically distinct, and I venture to suggest
that they only constitute a recognisable race or variety of an already
known species.
The chief object of this note, however, is to make complaint
respecting the name which Mr. Ford has imposed upon his so-called
species. .
When he published Greegori as a varietal name, it was already
five years previously preceded by Mr. Melvill’s varietal name coloba,*
and therefore there is no question I think, which name should be
employed if this variety be regarded jas a distinct species. Right
and justice (and even courtesy) at once direct us in the present case.
Mr. Ford is under the impression that Mr. Melvill was in a state
of uncertainty whether the form in question was a variety of cruenta
or caurica. I find no such impression conveyed by Mr. Melvill’s
sentences which are criticised by Mr. Ford. Moreover, in the cata-
logue of species (1. c., p. 243), Mr. Melvill ranges the var. coloba
under cruenta and in addition gives a representation of the ventral
side of the shell (Pl. I, fig. 7).
LAND MOLLUSCA OBSERVED IN THE GASPE REGION,
A. W. HANHAM, QUEBEC.
About the middle of May last I left Quebec for Gaspé Basin, by
the way of Port Dalhousie, N. B. and the steamer ‘“ Admiral.”
It was my intention to spend a week or more in this district collect-
ing shells and insects.
Unfortunately I found the season very backward up there, the
weather too was wet or cold during my stay ; owing to this but little
collecting could be done, and I was more than disgusted having
journeyed so far for so little purpose. .
The following specimens were taken or seen at Barachois, near
Mal Baie; this village is at the inner end of a deep bay, and is
distant from Gaspé Basin some 25 miles, and from Percé about 10
miles.
With a few exceptions the land shells collected were found living
in the grass on a sandy hillside close to the beach. The open coun-

66 THE NAUTILUS.
try was too wet and the woods were too full of snow to be worked at
all, in fact it was only in places on the hill side that the snow had
melted.
A broad sandy bar, some 5 or 6 miles long, cuts off the ends of
the bay at Barachois, leaving a narrow channel at one end: on this
bar I was surprised to find Pupa muscorum and Vallonia costata in
the sand under pieces of wood. Z. radiatulus, P. striatella, A. harpa
and F’. subcylindrica occurred here rarely, as well as a Vertigo, of
which two specimens only were taken.
Helix hortensis was very common on the hillside, generally buried
in the sand ; several varieties were taken; the plain form seemed to
be the least abundant. At the entrance to some burrows I found
quite an accumulation of empty shells, and nearly all being entire,
many were in very fair condition.
A little collecting under more favorable circumstances would no
doubt materially increase this list, from which several of the North-
ern or universally distributed species are absent.
At Gaspé Basin, Limnea palustris, catascopium, desidiosa, and
one Physa, most likely heterostropha, were found in drift. Some
marine species were also taken, but are not yet identified.

THE NAUTILUS. 67
A NEW GASTROPOD FROM NEW JERSEY.!
BY H. A. PEESBRY.
At the regular weekly meeting of the Academy of Natural Scien-
ces of Philadelphia, October 18, 1892, Mr. H. A. Pilsbry exhibited
a series of specimens of a large species of Chrysodomus, belonging
to the subgenus Sipho, which he had received from Messrs Witmer
Stone, Chas. LeRoy Wheeler and John Ford. He stated that the
specimens were cast upon the shore during severe gales from the
south east, and were evidently derived from a submarine stratum
which was disturbed and broken up at those times. Associated with
the Chrysodomus were examples of Buccinum wndatum, Urosalpinx
cinereus of extraordinary dimensions, and Chrysodomus (Sipho)
Stimpsonii, the latter being well developed and typical in sculpture:
The age of the deposit cannot be definitely settled at present, but
the evidence at hand indicates that it is post-pliocene.
~ The following description of the new species was offered :
Curysopomus (SipHo) Sroner (PI. III, figs. 1, 2, 3,). Shell
obese-fusiform, rather thick and solid, with strongly convex whorls
separated by deep sutures. Sculpture consisting of strong spiral
cords, equal on young specimens and on the spires of adults, but
which alternate with smaller intermediate cords on the body-whorl
in full grown specimens. A young shell therefore has about 20, an _
adult 40 spirals upon the body-whorl. The aperture is oval: the
eanal is strongly curved to the left and backward.
Length 72, greatest diam. 45 mm.; length of aperture and canal
51mm. The largest individual measures, length 100, breadth 64,
length of aperture 73 mm. Both of these, as well as all specimens
seen, have lost several of the earlier whorls; so the length of a
perfect individual would be proportionately greater.
The more prominent features of this species are the swollen form,
deep sutures, the strong spiral sculpture, and the strongly recurved
canal.
The localities whence specimens have been obtained are as
follows: Point Pleasant, N. J. (Witmer Stone); Sea Isle City, N.
J. (John Ford, Oct., 1892); Cape May, N. J. (C. LeRoy Wheeler,
1891.)
Prof. A. E. Verrill of Yale College very kindly compared spec-
imens of this species with the collection under his charge (a collec-
tion vastly richer than any other in mollusks of the north-west
Atlantic.) He writes as follows:
“T have made a careful comparison of the Sipho sent by you with
our series,
68 THE NAUTILUS. f
“Tt differs notably from any thing we have, and is probably, as you
suppose, an undescribed species, unless described as a fossil. We
have specimens of the ventricose varieties of S. Stimpsoni, which
equal this in stoutness, and nearly equal it in curvature of the col-
umella, but the whorls are less ventricose, the shoulder less swollen,
the sutural region less deep, and the sculpture is very much finer.”
Comparisons have also been made by myself with the Atlantic
Siphos in the U. S. National Museum, and of course with the recent
and fossil series in the collection of the Academy.

To judge from such works on the Mollusca as I have had access to,
Indiana has not been regarded as having a Molluscan fauna worthy
of the attention of the Conchologist. It is not often mentioned in
giving localities. W. G. Binney in his very valuable Manual of
Am. Land Shells, prints a list of his large collection as presented to
the Smithsonian Institute; some 312 species and varieties, only men-

ON A COLLECTING TRIP TO MONTEREY BAY.
BY WILLIARD M. WOOD.
The editors of the Nauriius have asked me to write ashort arti-
cle for the Navritus, while I am here, on my trip to this once
famous collecting ground.
Now that I am about to leave for San Francisco, I feel sorry to
think that I have not devoted more time to the collection of speci-
mens. Of course, there have been many long drives to be taken, a
dip in the surf once in a day, huckle-berry expeditions with friends,
and a thousand and one things to be done, while stopping at a sum-
mer watering place.
Between these “sports,” if I may be permitted to call them such,
I have managed to find time to do some collecting.
The hotel at which I am stopping is situated within five hundred
yards of the beach. To the north, runs a very smooth beach, |
devoid of rocks of any character for some fourteen miles. To the
south, and extending for many miles, is a very rocky stretch. To —
this rocky portion, almost all of my collecting trips were confined. —
Monterey is no longer the famous collecting ground it used to be. |
The increasing population at and around Pacific Grove is driving
away all the land shells. The deadly sewerage flowing from the ©
various towns into Monterey Bay is killing the marine shells. —
However, new and very interesting species are occasionally brought —
up from deep water by the dredge. —
Early in the morning, on the 28th of June, I started by steamer
from San Francisco with my shell collecting outfit, consisting of glass —
pill bottles for small shells, paper boxes, cigar boxes, cloth bags, —
long, thin pieces of wood with rubber bands attached for the Chi-
tons, alcohol stove and pan for the killing of bodies of the shells, |

eotton batting, long rubber boots, an immense sun hat, a chisel to
detach Haliotis shells from the rocks, ete.
; I arrived here at seven in the evening and although the trip down
| was rough, and our little “tub” rocked dreadfully, causing me to
be sea-sick, it nevertheless did not prevent me from starting right in
_ and collecting as soon as my feet rested on terra firma. On that
_ evening, I began collecting at seven o’clock and as it was very light
at that hour, I continued to collect along the beach until eight. I
am very glad I did so, as it netted me some beach-washed species
_ which I have not come across since.
F I selected a week when the early morning small low tides
occurred. Thus, one morning I devoted to the collection of Hali-
otis ecracherodii, another morning I went in search of Littorina
_ planaxis, another for Chlorostoma costatum, Acmza scabra, Nassa
* mendica, ete.
; During this second week, when no morning low tides have
_ occurred, I have gone among the rocks, gathering any and every
species which was so unfortunate, nay, I should say, fortunate, as to
. be placed within my reach.
7 Priene Oregonensis Redf. will be noted as having been collected
_ here. Ido not as yet understand how this large and beautiful
_ northern shell should be found so far south. It could not have
iN drifted into the bay, as it was a fresh, perfect-lipped specimen.
+ I may also mention that in a letter recently received from Mrs.
M. Burton Williamson, of University P. O., Cal., that lady informed
: me that Psammobia rubro-radiata Nutt., is not found north of San
Pedro Bay. As will be noted, I found one specimen, alive and per-
fect. It is truly a beautiful shell. The inside of both valves
resembling delicate porcelain.
I am exceedingly sorry to think that I have no dredge here with
me, as I feel positive I could gather at least five times as many
specimens as I have already collected.
In the following list, the number of specimens taken is given
after each name, and will serve to show the relative abundance of
the species.

NOTES ON PAPUINA.
BY CHARLES HEDLEY, AUSTRALIAN MUSEUM, SYDNEY, N. S. W.
All Papuina’ are arboreal; this habit is as “good” a generic
character as any anatomical feature couldbe. Parenthetically, I
may remark, that my friend Mr. Brazier, who has probably gath-
ered more living Papwina than any other naturalist, agrees with
me that thejaccount (Ann. Mag. N. H, (4) xx, p. 242) of a Papuina
clinging half way up a reed in a brackish swamp is quite incredi-
ble. The usual position of Papuina is upon the trunks or limbs of
trees where an unpracticed eye might take it for a rough bit of
bark. In southern Europe the Macularia perch just so on precipi-
tous rocks ; indeed, I recollect there capturing an H. niciensis on an
olive tree in exactly the manner affected by the Papuina in New
Guinea.
A small group of Queensland snails, viz, conscendens Cox, fucata
Pfeiffer, and bidwilli Cox, seem to differ from the main body of the
genus in their habits. Not the stem or branches, but the leaves of
trees are chosen by these for their favorite abode. To suit the sit-
uation the shell has been modified until the contour would suggest
Partula rather than Papuina. The more conical shape has proba-
1This name is now generally used for the conical Helices characteristic of the
Papuan and Solomon Island faunas, formerly called Geotrochus.
74 THE NAUTILUS.
bly been adopted for greater safety in the exposed tree tops; to the
same end every superfluous atom of weight has been abandoned,
the shell reduced to the thinnest, and the reflected lip dispensed
with. Under the lens the apex is seen to be of one and a half
whorls, black or darker than the adult shell, smooth and subglobose,
Oblique grewth lines are the predominant features of the adult
sculpture; by flashing the shell in the sunshine under a lens, an
extremely minutely shagreen surface is perceptible in the gleam, and
here and there broken lengths are decipherable of engraved spiral
lines. Viewing the shells of these three species by transmitted light
the color markings are seen as translucent spaces in the opaque
shell. I should interpret these signs as indicating a descent from
an ancestor like naso and macgillivrayi through a form very close to
bidwilli, Pfeiffer.
The minute almost imperceptible shagreen surface may represent
the coarse sculpture of naso; the evanescent spiral lines are tracea-
ble from the clear cut lines of macgillvrayi through the fainter
sculpture of bidwilli Pfr., to their vanishing representative in bid-
willi Cox. But the minute subglobose apex and especially the
translucent spiral color bands ally this group unmistakably with
Papuina. Admitting this, in default of anatomical examination, it
will be necessary to rename the shell hitherto known as Bulimus
bidwillt Cox, lest it should clash with that other Papuina described
by Pfeiffer as Helix bidwilli. I therefore propose that in allusion to
its peculiar habits, it be henceforth called Papuina folicola.
Between these leaf-dwelling Papuina of Queensland and Bulimus
mageni Gassies, of New Caledonia, I note a strong resemblance in
color, form and sculpture, but especially in their translucent color
bands. Until further research settles authoritively the position of
this species I would provisionally class it with the foregoing.
SAN PEDRO AS A COLLECTING GROUND.
San Pedro, California, is remarkable for the number and variety
of recent and fossil mollusks.
New forms and an unusual abundance of known species are con-
stantly being found.
This is due in a great measure to the extension of the Government
breakwater, which has made changes in the sea currents near the
THE NAUTILUS. (Ay
shore, and caused the tide water of the harbor to scour out the chan-
nel and drift large quantities of sand over the shallows.
By this means new homes are made for wanderers, and old inhab-
itants are washed from their moorings and swept by the tide within
reach of eager Conchologists.
It is surprising, however, how seldom the year’s abundance of any
species repeat themselves.
At one time Nassa fossata Gld., at another Periploma discus
Stearns; at another Lima orientalis Cpr.; or Scalatella striata Cpr.,
are found by the dozen, or score, or hundred in San Pedro Bay or
vicinity, and then for years after only a few are found at a time.
The sea conditions are unsettled. This keeps local collectors
alert.
Within a few months I have found a specimen of Tritonium
gibbosum which is new to California, and one of Cylichna cylindracea
var. attonsa Cpr., which is new to San Pedro. Bothshells are beach
worn.
This summer I spent July at San Pedroand added a number of
new specimens to my collection besides learning many interesting
facts about habits and habitat of molluscs.
A student only gets a half knowledge who cannot collect speci-
mens and study the living animals in their native haunts.
July seems to be a favorite month for many species to lay their
eggs.
Mitra maura (Ide), fastens her capsules to the underside of stones;
the Naticide place their “sand collars” in the damp sand; Bulla
nebulosa Gld. coils up her yellow strings on the grassy flats, and
Haminea virescens Sby. chooses the same place and time, but has a
different shade of yellow for her egg-strings.
I was much interested in the eggs of Acteon (Rictaxis) puncto-
ceelatus Cpr.
This mollusk has been rare, and I am inclined to think it only
comes inshore in numbers during the breeding season and after that
burrows in sand in deeper water for the rest of the year. In July
we found them by the hundred.
The eggs are Jaid in a white string three or four inches long that
coils so as to form a loose spiral.
The spirals are anchored, by some means, so firmly that the wash-
ing of rough surf does not sweep them away.
76 THE NAUTILUS.
ia
They so closely resemble the spiral pattern on the adult shell
that the collector, looking down through the water, not unfrequently
stoops to pick up what he thinks is one of these little gasteropods
and finds a string of eggs in his fingers.
I visited Portuguese Bend and learned that Purpura emarginata
Desh., which I found in quantity more than a year ago, is a resident
or a comer and a goer, for more than a dozen were collected this
summer. Its habitat is limited to a small mussel bed.
Other localities so much like this mussel bed, that one would
consider them suitable dwelling places do not boast of a single Pur-
pura; so that something besides collectors must disturb this usually
common species.
I collected at San Pedro an abundance of Acmaa paleacea Gld-
on the eel grass.
These close clingers love the grass on the outside of the island
that is swept by heavy swells and where the water scarcely leaves
them even in very low tides.
Their more peaceful cousins Aemea depicta Gld. will probably be
found swaying with the grass in the stiller waters of the bay, for
dead shells have been frequently found in the drift.
In the quiet bay quantities of drift material are washed up with
alos and eel grass during medium tides.
This is rich in minute forms. It consists largely of broken shells
of molluscs and crustaceans, but there is a sufficient quantity of
Pedipes, Siphodentalium, Tornatina, Cecum, Truncatella, Mitromor-
pha, Turbonilla, Cerithiopsis, Triforis, Diala, Mumiola and other wee
bodies to amply repay any one for carrying away a few pounds of
the drift to be dried and sorted at home.
The sifting and the sorting with a microscope takes so much time
and patience, that the new and rare species hidden in my bags of
drift must wait a more convenient season.
The yearly extension of sand flats at San Pedro, must make
happy all sand loving species such as Bulla, Sigaretus, Natica, Ol-
vella and scores of bivalves.
Besides these sandy stretches there are mud flats, rocky points,
brackish water, fresh water, smooth or rocky beaches enough to
make San Pedro an ideal collecting ground.
Although nearly all the localities are easy of access for the Con-
chologist, or the collector who “makes shell flowers,” there are
changes enough taking place to insure a good supply of shells.
THE NAUTILUS. Ti
A storm that stirs up the depths makes a grand holiday, but
nearly every visit, in storm or calm, repays the student by some
epee of the life history of some soft—hard dweller of the sea.

PRELIMINARY NOTES ON TASMANIAN LAND SHELLS.
BY HENRY SUTER.
Since I became acquainted with the New Zealand and Tasmanian
land and fresh water molluscan fauna, some four to five years ago.
I came to the conclusion that both are very nearly related, though
this opinion is not shared by Conchologists generally. On several
occasions I expressed my views, especially when describing Charopa
subantialla and Ch. mutabilis. It is well known that no attempt
has been made to classify the Tasmanian land shells; all the Heli-
cidze have been simply placed in that “olla potida” genus Helix,
Mr. Charles Hedley of Sydney, was first to publish structural details
of the animals of some Tasmanian land shells (Proc. Linn. Soc., N.
S. W. (2) VI, p. 19). Descriptions and very good figures of the
animals and the dentition were there given of Bulimus dufresni, B.
tasmanicus, Anoglypta launcestonensis, Rhytida lampra, Helicarion
verreauxi and Cystopelta petterdt.
I have not been successful in procuring land shells with their
animals from Tasmania, and I therefore decided to sacrifice part of
my collection. There were some specimens with the animal dried
in them and these I used for preparing the jaws and radule. I
have just finished the microscopic slides and have not yet had time
to study them carefully. However, I ascertained a few facts, which,
I feel sure, may prove of great interest to Conchologists, though
my communication is only provisional.
Conchologists of course know that the genera Endodonta, Charopa
and Rhytida are common to New Zealand and Tasmania. The
new facts I ascertained of genera or sections of genera found in New
Zealand as well as in Tasmania, and part of Australia in some cases,
are the following :
Genus Gerontia.
Section Flammulina, thought to be confined to New Zealand
only. I think that H. Jungermannie Petterd, belongs to this sec-
tion, though I am not yet quite positive.
78 THE NAUTILUS.
Section Thalassohelix, hitherto not recorded from beyond New
Zealand. There is no doubt that H. fordei Brazier, (—petterdi Cox
—=positura Cox) must be classed under this section, and very likely
also H. austrinus Cox, H. allporti Cox, H. helice Cox, H. medianus
Cox, H. mixta Cox, H. tabescens Cox, H. tranquilla Cox, H. trajec-
tura Cox, which are said to be varieties of H. fordei. This species
is found alsoin Australia.
Genus Laoma.
Section Phrivgnathus, a genus which was thought to be peculiar
to New Zealand “par excellence.” Now I am quite sure that the
following Tasmanian mollusks belong to this section :
H. cesus Cox (and var. occultus Cox ?) H. henryana Petterd, and
HF, pictilis Tate; the latter being found also in Australia.
Genus Rhenea.!
This genus of which two species are known from New Zealand, is
in Tasmania represented by Hyalina nelsonensis Brazier (=—fulge-
trum Cox, and very likely H. dyeri Petterd, though the dentition
of the latter is unknown to me).
I am confident that on examining my slides there will be some
other sections of G'erontia to be placed on record in my next com-
munication on Tasmanian snails.
In future we may no doubt be able to distinguish in New Zealand
and Tasmania two different immigrations of land mollusca, one
having spread from north southward, and another, the antarctic,
migrating from south to north.

SOME (RESPONSIVE) REMARKS RELATIVE TO CYPREA GREEGORI ©
FORD.
BY JOHN FORD.
In the note on OCyprea Greegori Ford, published in the October
number of the Nautiivs, the writer, Mr. Edgar A. Smith, of Lon-
don, rather forcibly remarks that “the new French School of Con-
chologists would probably agree with Mr. Ford in considering the
shell in question specifically distinct from C. eruenta,” but, “he
1A genus of carnivorous, jawless snails allied to Riytida and Paryphanta, for-
merly called H/ea Hutt. (preoc.)—Ld.
THE NAUTILUS. 79
was glad to say that in England (and, he hoped, in America also),
the ideas were not so far advanced (?).” In support of the last
proposition, he says: “ Although examples of this shell have been
in the National (British) collection for more than fifty years, no
British path has ever suggested that they belonged to a distinct
species.” This statement is apparently correct, but he might have
added quite as truly, that nearly all of these years were required
for “British authors” to find them worthy even of varietal distinc-
tion.
In view of this ‘state of things,” it is not at all surprising that
Mr. Smith should consider it a “bit of presumption” for an
American student, having less than one year’s knowledge of the
shells, to attempt to lift them above the plane of varietal contro-
versy. |
It matters not that this student has examined hundreds of speci-
mens, all showing the same distinctive specific characters. His
“ideas” do not agree with English formulas, therefore they must
necessarily be too far advanced.
Nevertheless, the new species, C. Greegori, has doubtless come to
stay, since it has been endorsed already by quite a number of emi-
nent (American) Conchologists, whose opinions, were it necessary to
mention names, would at once be accepted as weighty. In
regard to Mr. Smith’s admission, “that examples are pretty easily
separated from the typical form of eruenta,” it may be said that I
have seen no specimens whatever that could not be separated on
sight from any form of C. cruenta. Just here, it may also be said,
that I do not hesitate to claim (asin my former article) priority
both for the name and description of the shell; and this claim is
made in face of the fact that British authors, as a rule, command
my highest respect and esteem. But while according this, I do not
expect them to throttle, without ample reason, even the humblest
seeker after knowledge.
It is only just to myself. to say that not until my first description
was in type, did I learn that Mr. Melvill had ever referred to the
shells, nor, so far as I could ascertain, was this reference known to
any of my Conchological friends. Indeed, the gentleman who
finally gave me the information has, from the first, regarded them as
C. caurica var. As Mr. Smith suggests, I was then, and still am,
under the impression that Mr. Melvill’s sentences left the reader in
a state of uncertainty as to whether he considered the shells a
80 THE NAUTILUS.
variety of cruenta or of caurica. That his purpose is more plainly
shown in the list of figures given is apparent, but as the volume
examined by me was an uncut one, this list was not at the time dis-
covered.
Since many readers of the Nautitus may lack the opportunity
of seeing Mr. Melvill’s statement, and judging for themselves as to
its clearness, it is given here verbatim, as follows: “ C. cruenta
(Gmel.) is very nearly allied to the preceding,” [i. e. cawrica] “ and
the variety coloba (fig. 7), so-called from the stunted appearance, is
also figured in Sowb. Thes. f. 190, as cawrica var. ; it would appear
nearer this species: the base is always brighter coloured, and teeth
interstices bright red. I possess stunted caurica with which this var.
cannot be mistaken.”
Now if any reader of the Nautruus can show by these sentences
to which of the two species Mr. Melvill assigned the variety, it. will
be a pleasure for me to acknowledge my error in questioning his
meaning. But whether the language refers to one variety or
another is really of very little moment at this time, since it can in
no way affect the present status of the shells. Be it agreeable to
Mr. Smith or not, the fact remains that Mr. Melvill’s so-called
description is simply meaningless and void, embracing as it does,
just three words, viz, “base brighter colored,” meaning, of course,
brighter colored than the type shells he had in mind.
But how brighter or how colored? They are certainly not
brighter than both cruenta and caurica usually are; and there is not
a hint as to whether the color is green, blue, yellow or any one of a
dozen hues, yet with such a description at hand, the student was
expected to distinguish the shells from all others. It is true that
there are other words besides the three quoted, viz, “teeth inter-
stices bright red.” Unfortunately, however, the same sentence
is used in the description of the type ‘C. eruenta, (to which species
Mr. Smith assures us the variety coloba relates) and is therefore
entirely worthless as a distinctive varietal character.
For these reasons, I claim that the name coloba is absolutely
devoid of collateral support, since nothing can be plainer than the
fact that without an accompanying description intelligible enough
for comprehension, the suggested name or title of a shell is of no
scientific value whatever.
But then, as Mr. Smith intimates, there is the figure! and surely
that counts for something.
THE NAUTILUS. 81
Perhaps it does. But not for anything of special importance in
this connection, for Kiener, many years before, gave us a pair of
figures quite as good; not to mention that made by Sowerby some
years later.
It should be understood that these references are not made in
defence of the present specific standing of the shells, but mainly in
deference to those readers who may have missed seeing my former
articles relating to them. The species, i. e., C. Greegort, is doubtless
already sufficiently fortified to prevent successful assaults from any
quarter.
In conclusion, it might be well to add, that Mr. Smith’s rather
emphatic “reminder” of my lack of courtesy, is wholly gratuitous,
and therefore does not call for comment.
In the interest of peace, however, it is accepted “ with thanks,”
and filed for future courteous consideration.

THE SHEEPSCOTE RIVER.
BY REV. HENRY W. WINKLEY.
The fauna of the eastern coast of New England, aside from the
species which characterize it as a whole, has a number of small areas
where the oyster, quahog and other southern forms exist. The most
conspicuous of these areas is Northumberland Straits, where the
oyster is abundant enough to be of commercial value. Other
points, where the Virginian fauna occurs, are a few sheltered spots
on the east coast of Nova Scotia, in Minas Basin, Casco Bay and
Massachusetts Bay, with a few outliers of less importance.
These spots on the coast are widely separated from each other,
and have in the near neighborhood animals which are adapted to
the colder waters. Some few years ago the present writer published
a list of thirty species found in Northumberland Straits." The
present summer was spent in Wiscasset, Maine; this and a visit to
that place three years ago enabled me to dredge in many places in
the Sheepscote River.
Wiscasset is ten or twelve miles from the sea and the river is
practically a salt water bay or fjord. Its depth is ten fathoms in

places, and at no point is it shallow. The width, on the other
hand, is but a few hundred yards except at Wiscasset, where it is
three quarters of a mile wide. The river is famous for its scallops,
Pecten magellanicus Gmelin, these occur for the most part in the
lower part of the river.
It was frequently reported to me that oysters were to be found ©
“up river” four or five miles. I am sorry to say I had but one day
“up river;” that trip, however, revealed the fact that a very nar-
row spot known as the Falls, separated an upper basin from the
main part of the river. Here in the warmer waters oysters do
occur, but very few and far between.
few of the old companions noticed in Northumberland Straits, and
abounding south of Cape Cod.
As a whole this river is rich in specimens, and the cold and warm
water species are by no means distant neighbors. Some forms are
dwarfed, some like Budlinella alba, are, colored probably by
iron to a darker shade than the normal. I believe that more spe-
cies may be added to the list by a more careful search above the
place dredged. I give the list of those found by me in the area
extending four or five miles each way from Wiscassett.

AMERICAN ASSOCIATION OF CONCHOLOGISTS.
The President of the Association regrets that he has been com-
_ pelled through stress of business engagements and other matters, to
temporarily suspend his correspondence upon Conchological mat-
ters, but would be glad now to hear from any of the members,
especially those whose letters have not be attended to promptly.
The Association has recently not been so active as formerly, but
everything looks fair for a go-ahead, prosperous season. Nearly
200 members are enrolled in the Association, and any proposals of
new members will be acted upon promptly by the officers. Such
proposals should be made to the Secretary, Mr. Chas. W. Johnson,
Wagner Institute, Philadelphia.
Members desiring to forward fine specimens of shells to the
“ American Collection,” will kindly communicate with the Presi-
dent, Mr. John H. Campbell, 1009 Walnut Street, Philadelphia,
sending him lists of such species as they wish to forward. Due
acknowledgment of shells received will be made in the pages of the
“ N AuTILus. ”
The most recent addition to the collection has been a fine series
of fossil species from the Miocene and Pliocene of Maryland, Vir-
ginia, North Carolina and Florida by Mr. Joseph Willcox of Phil-
adelphia. The collection, already, is one of the finest “special col-
lections” in America, and bids fair to surpass all others. Each
species is carefully examined, named, mounted and placed in the
eases set apart by the Academy of Natural Sciences and the collec-
tion as a whole, is kept separate from the general collection of that
84 THE NAUTILUS.
institution. The name and address of each donor with date of
reception, are neatly written on the cards, upon which the shells
are mounted and the officers of the Association give the collection
their personal supervision.
Changes of address of ae should be promptly noted to the
Secretary.
NOTES AND NOTICES.
Mr. F. H. Lattin, whose Natural History establishment at Albion, —
N. Y., has long been well known to many of us, has recently
founded a “branch” in Chicago, where we lately had the pleasure
of looking through his large mass of material. Mr. Lattin has now
a considerable stock of shells in addition to his departments of orni-
thology and oology, and it is with pleasure that we announce this
first commercial enterprise in the Conchological line in the West.
F. H. Lattin & Co. now occupy a handsome and well filled build-
ing at 8571 Cottage Grove Avenue.
A VIGOROUS EDITORIAL from the pen of Mr. J. Ritchie, Jr., deal-
ing with the recent postal ruling against natural history specimens,
appeared in the Commonwealth (Boston), Saturday, September 25.
VARIATIONS OF STROBILOPS HUBBARDI.—In looking over our
collection of this species I find that over half of them have three
teeth, but about a third have four, and I found one with five. We
have collected them from several different localities, but all in Flor-
ida, and nearly all in this county, some near the coast and some 16
to 18 miles inland.—G. W. Webster, Lake Helen, Florida.
A syNonyM oF LEPTroTHyRA.—It seems to have escaped notice
hitherto that Gabb’s genus Petropoma (Journ. Acad. Nat. Sci.,
Phila. viii, p. 281) is founded upon a species exhibiting all the —
essential features of Leptothyra. The operculum and shell are very —
like in structure to the granulose species of the central Pacific.
Gabb, in his description, mistakes the inside for the outside of the
operculum. Being later in date than Leptothyra, the name Petro-
poma becomes a synonym.—ZH. A. P.

LAND AND FRESH WATER SHELLS IN THE ROCKY MOUNTAINS.
Bi Geo. W. TAYLOESVICTORIA, B.. C.
In the October Nautixus there is ashort paper by my friend
Mr. Hanham upon the shells found by himself during a trip in that
rather out of the way Canadian locality, the Gaspé region.
It may be interesting to have a record of a small collection made
by me a few weeks ago in another little-known locality at the oppo-
site end of the Dominion viz.: Laggan near the summit of the Rocky
Mountains.
I had received earlier in the year from Mr. T. R. Bean of Lag-
gan, a nice little collection of shells which included specimens of
what Dr. Sterki considers to be the true Pupa hoppii of Moller,
and this tempted me to stay over for a couple of days when passing
through Laggan last September on my way to Toronto.
Dr. Bean most kindly showed me all the best localities known
to him, and our united exertions were rewarded by the discovery of
several species that he had not previously recognized, including one
which I believe had not before been found in Canada.
In the rivers, the Bow and the Pipestone, we could not find any
shells at all, the waters being cold and thestream rapid in each case,
but in all the little creeks and swamps Linnea palustris abounded
and Planorbis parvus occurred in less numbers. In a small Jake
not more than a mile from Laggan we found, in addition to the
86 THE NAUTILUS.
species above named, 3 others—Planorbis trivolvis Say, common,
Pisidium abditum Hald., rare, and a Valvata, which I suppose to be
virens Tryon, 6 specimens only.
No Physa of any kind were observed, nor has Dr. Bean as yet
found any species of Unio, Anodonta, or Sphwrium. )
The land shells enumerated below were all found under logs or
under pieces of board in the neighborhood of the settlement and
along the banks of the rivers. Vitrina limpida Gould, Hyalina
arborea Say, Hyalina radiatula Alder, Conulus fulvus Drap., Patula
striatella Anth., Vallonia costata Mull. (form gracilicosta Reinh.,
‘teste Sterki), Ferussacia subcylindrica Linn., Succinea avara Say,
and a species of Vertigo closely resembling gou/dii, were all com-
mon. \
Pupa hoppii Moller, was not very common in the spots I searched
and I only secured 8 specimens. Still less frequent was Pupa alti-
cola Ingersoll, which I had here the pleasure of finding for the first
time.
Dr. Bean has in his collection, besides the above, specimens of
Pupa pentodon Say, which he took a few miles to the west of Lag-
gan; and a second species of Succinea perhaps S. ovalis Gould.
Lastly some slugs which were probably Limax hyperboreus West.,
were observed by us but not collected.
The altitude of Laggan is about 5,200 feet above sea level and the
locality is interesting, as being nearly at the summit of the Rocky
Mountain range, which seems to form, in Canada, a hard and fast
line of demarcation between the eastern and western species of Mol-
lusea.

HHECKEL’S PLANKTONIC STUDIES.
All interested in the life of the open and deep sea, the so-called
pelagic or Plankton fauna, will be interested to read the translation
of Prof. E. Heckel’s paper of 1890, which is printed in the Report.
of the U. S. Fish Commission for 1889-91, pp. 565-641. -
Some of the German polemics are omitted, though a sufficient
amount remains to spice the article in a lively manner. There is
much reason to believe that Heckel, who has had no experience in
deep sea work, has overestimated the evidence in favor of zonary —
distribution of life in the deep sea. Certainly the observations of

ssiz ‘and Tanner are superior by reason of their better apparatus
y heretofore made, and they seem to show that with the excep-
ti on of a superficial zone of a few hundred fathoms and a thin zone
in imediately over the bottom, the animal kingdom is represented in
: - the intervening region by the dead bodies of sinking animals only,
at nd has no peculiar fauna of its own and but little life. There is
no obvious reason why this must be so, but the most carefully
checked observations yet made indicate that it isso. Apart from
this one point, the paper of Heckel gives a most interesting, accu-
rate and vivid idea of the pelagic life of the sea, and one which
.. ~ every one may read with profit. The vast experience in surface and
coast collecting which the Jena Professor has had, enables him to
speak from experience in this direction, and the material obtained
by others, on the Challenger and elsewhere, which he has worked
a p>’ has given him ereat familiarity with the Plankton fauna.

CONTRIBUTIONS TOWARD A REVISION OF THE TASMANIAN LAND
MOLLUSCA.
BY H. SW@REE.
: Since I wrote the “ Preliminary Notes on Tasmanian Land Shells,”
I have sacrificed many more specimens of my collection for the
study of the dentition, and, as I have just finished the work, I wish
5 9 give here the result of my investigations.
or giving the results of my study, it will be necessary to say
a few words on the classification of the New Zealand Helicide.
ir. H. A. Pilsbry proposed (Nautitus, VI, 1892, No. 5, pp. 54-57)
v anew classification of N. Z. Helicidee, the main feature of it being
2 forming of one genus, Grerontia, of these former genera consti-
tuting my family Phenacohelicide. Later on he published (Proc.
ad. Nat. Sci. Philada., 1892, pp. 387, ee) a “ Preliminary Out-
2 of a New Classification of the Helices,’ in which he included
nde the one genus Endodonta, the following groups: Endodonta
r., Ptychodon (—=Maoriana), Charopa, and his genus Gerontia.
Di n not agree with this latter classification, as the author was
inder the impression that Endodonta, Charopa, etc., possess a muc-

ous tail gland, which is not the case. Moreover, the jaw in Endo-
donta and Charopa is only striated, whilst stegognath in Gerontia,
and the radula in the latter is more or less distinctly pseudozon-
itoid. I am of opinion that the separation of Gerontia from Endo-
donta is fully justified ; the patuloid shells being included in Endo-
donta, whilst the more zonitoid forms are embraced in Gerontia..
Mr. Charles Hedley and the writer substituted von Martens’
Flammulina for Amphidoxa of N. Z. authors, and as the genus of
von Martens dates from 1873, it must be used as the generic name
instead of Gerontia (1883).
The classification of the New Zealand Helicidz I propose, follow-
ing chiefly Mr. H. A. Pilsbry, is the following :

mania. Most remarkable is the preponderance of Gerontia, a sec-
tion represented in New Zealand by two species only, and of Phriz-
gnathus, which is also well represented in New Zealand. <A very
striking feature is the almost total absence of Endodonta, there
being one species of Endodonta s. str. (E. dispar Braz.) and one of
Charopa known from-Tasmania. Rhytida is more abundant in
Tasmania, whilst Rhenea is represented by two species in each

There can be no doubt about the great antiquity of these forms,
as they must date at least from the Cretaceous period.

IN MEMORIAM—ROBERT WALTON.
Pe eesti) |
It is with sad hearts that we record the death of our young friend
Robert Walton. While out collecting on Saturday, November 11,
along the steep bank at West Conshohocken, he slipped and fell as a
freight train was passing below, receiving a terrible gash on the
head and having one of his legs crushed beneath the wheels, from
which he died at 8 p. M., the accident occurring about noon. He
was born in Halifax, England, July 17, 1875, and came to this
country in the summer of 1889. He was a collector from boyhood,
studying nature with that enthusiasm which only a born naturalist
ean. He was not content with a collection of shells alone; his was a
collection of the mollusea. He studied their anatomy, working out
their jaws and dentition, the darts from the Zonites, and the testa-
ceous shell-plates, from the Limaces. He was a close observer, and
by his zealous collecting he found many forms not before recorded
from this section. Among his rarities were reversed specimens of
Zonites cellarius and Zoniles ligerus, and I remember his saying,
when we met only a few days before his sad accident, that he found
the reversed Zonites cellarius at West Conshohocken. He was to be
appointed as a Jessup student at the Academy of Natural Sciences,
and was looking forward, as only a young heart can, to the day —
when he would be studying and working there among the objects
he so dearly loved. Mr. Pilsbry was looking forward with a great
deal of pleasure to the time when he would have such a valuable

‘This new work, of which the first one of the four parts has now
appeared, aims to present a complete introduction, key and index
to the genera, subgenera and species, of the Helices of the world.
_ Each group, whether generic, subgeneric or sectional, is defined, and
oe - its species enumerated ; the type and usually a number of prominent
pereses of each is figured, and the anatomy is described and figured.
_ The first genus included in the “ part”’ just issued, is Trochomor-
pia, an important Asiatic and Polynesian group, many specimens
of which are in most collections. Although it has generally been
associated with the Helicids, Trochomorpha really belongs to the
— Zonitidee and it is admitted to this work only because the species
have been generally known as “ Hela.”

The following genera belong to the Helicoid group Haplogona.’
They have a shell with simple, non-reflexed lip, more or less similar
to our “ Patula” alternata, ete. The genital system lacks all appen-
dages. The foot has on each side a border above the margin bounded
by a groove (easily seen in alternata, solitaria, etc.). This last char-
acter is shared with the family Zonitide. The jaw exhibits consid-
erable variety in the several genera. It is either (1) composed of
separate squarish plates, overlapping or imbricating, and only con-
nected by a common membrane (Punctum, Laoma), or (2) the plates
are soldered together, the outer edge of each being free (Flammutina,
Charopa), or (8) the plates are completely soldered together, their _
edges appearing only as vertical striz (Pyramidula-—=“ Patula”’).
The first type has been called Goniognathous, but falsely, as it has no
near relationship to the jaw of Orthalicus, etc.; the second type has
been called Stegognathous or “ plaited” ; and the third Aulacogna-
thous or “striated.” The three are really only stages of develop-
ment, and between the last two all intermediate forms occur.
The principal peculiarity of the generative system, besides its
simplicity, is the very low insertion of the spermatheca duct. The
teeth show no very characteristic features, except that in many
cases the inner cusp is retained on the laterals, as in the Pupide.
The genera of Haplogona may be briefly tabulated thus:
a. Jaw composed of separate plates, Punctum, Laoma.
aa. Plates of jaw more or less soldered together,
b. Tail having a mucous pore, Flammulina.
bb. No mucous pore
c. Australo-Polynesian forms, i Endodonta.
ec. 8. American forms, Amp hidoxa.
ccc. S. African forms, Phasis.
cecce. North temperate forms, Pyramidula.
The five last named genera include a great number of subgenera
and “sections,” all of which are defined and fully illustrated both
as to shells and anatomy, with lists of the species of each.
The group Haplogona as a whole may be regarded. as an ancient
and unspecialized type, formerly world wide in distribution. At
present a vast majority of the species retain their footing only on the
southern extremes of the three great land masses of the globe, and
2The genus Po/ygyra, formerly included in the //ap/ogona, does not belong there.
It has a solid, ribbed jaw and no grooves above the foot margin.

NOTES AND NEWS.
Iya recent letter from Miss Ida M. Shepard, she says: “ We
have formed what we call the Los ANGELES CONCHOLOGICAL
_ Cup, for the study of our local shells, and hope to take up the
_ West coast species generally later. We have eleven members, and
meet once or twice a month.” We heartily endorse this new organ-
ization for the study of the mollusea, and wish the club a success-

been published by Dr. Sterki in Proc. Acad. Nat. Sci. Phila., 1893,

seems desirable to record that they were from Davenport, Iowa, col-

is recorded by Sterki from the same locality. It may be added that
I saw Ancey’s MS. description in May, 1890.—T. D. A. Cockerell.
STROBILA HUBBARDI.—Noting your comments on S. labyrinthica
and vars., suggested to me the idea of comparing them with S. hub-
bardi. ,
There is evidently a close affinity between the two species, and —
the same tendency to variation in the number of teeth. I find'in _
the Hubbardi three constant teeth, but in nearly one-half of our
collection of several hundred there is an extra tooth between the
second and third tooth counting from the umbilicus, and in some
eases a fifth tooth beyond the third. The variety S. strebeli found — q
here in our locality is also an approach to S. hubbardi in its de-
pressed spire and dark color. They are also found in similar sta-
tions often together under the bark of old logs or on palmetto trees,
hidden in dirt or old rubbish. Hubbard? is a very shy snail, and I
have spent many days looking for them. At first I thought three
or four a good day’s find—G. W. Webster.
VITRINA LIMPIDA IN PENNsYLYANIA.—In my note on Vitrina
limpida Gld. in Pennsylvania which you published in the August
Nautitus, I promised to report the results of future visits to the —
place where the shells were found. I went down yesterday after-
noon and found 24 living shells, and as I could only go over a very
small portion of the hollow, owing to a very heavy growth of nettles, —
brambles and other noxious weeds, I think the shells must be very
plenty—in fact, I do not think I “ worked” over two or three
square yards at the most. * * * *
In continuation of my letter of October 2: On the 8th inst. I
again visited the place where I found the Vitrina limpida Gld., and
got 38 living specimens in about one and one-half hours, and went _
over exactly the same ground as in my former visit, though —
this time the space worked over was less than on October1. The
colony appears to be in a very flourishing condition, although dead
shells are very plenty. * * * *

NEW TERTIARY FOSSILS FROM RED BLUFF, MISSISSIPPI.
BY T. H. AEDRICH.
The fossil-bearing stratum designated by Dr. E. W. Hilgard as
the “ Red Bluff group,” occurs in Wayne County, Mississippi, near
Red Bluff station, and is exposed on the banks of the Chickasawharg
River. The fossiliferous stratum is four feet thick and contains
beautifully preserved specimens imbedded in a greenish clay.
Through the kindness of Prof. W. H. Dall I have had an oppor-
tunity to examine the collections of the National Museum, which
___-were obtained here by Mr. F. Burns and others and with a series
in my own cabinet have been enabled to list 135 species from this
bed. Of these 26 are peculiar; 25 are found also in the beds at
Jackson, Miss.; 54 occur also at Vicksburg, and 30 are also com-
mon to Jackson and Vicksburg. This bed, therefore, should be
_ ¢lassed with the Vicksburg series. The following are described as
new:
s _ Mitra lintoidean.sp. PI. 4, fig. 1.
Shell fusiform, whorls nine, somewhat turrited, densely but
coarsely longitudinally ribbed, a transverse impressed line behind
the suture gives the upper whorls the appearance of being beaded ;
_ aperture narrow, elongate; outer lip sharp, slightly incurved,
striated within, labium four plaited; canal open, rather short,
_ curved, a number of impressed lines showing upon the lower part
of body whorl. Alt. 27 mm.; diam. 8 mm.
This species differs from Pusimitra cellulifera Con. by its lack of

impressed revolving punctures and by being broader and much
heavier.
The ribs are almost obsolete in young specimens. Type is in
my collection. Examples in National Museum.
Cyprea Dalli n. sp. Pl. 4, fig. 2. 2 a.
Shell ovate, moderately elevated, surface highly polished,
crossed above by a number of lines not closely set, dividing the sur-
face into a series of facets, base ventricose; labrum very much
thickened, profoundly striated but the striations do not extend up
over the whole surface. ‘Teeth on outer lip alternate. The smaller
ones half the length of the others; aperture narrowed in some speci-
mens in the centre, in others regular and strongly denticulated.
Length 15 mm.; width 12 mm.; alt. 9 mm.
This shell is also found at Jackson, Miss. It resembles C. lintea
Con., and has been considered as that species. It is however larger,
with a more thickened labrum on which the striations do not reach
the body of the shell as in Conrad’s species, but stop half way; the
surface of this shell is very different. In C. lintea the surface is
completely covered with close-set, very fine lines, while this species.
has but few, and they are not impressed, some specimens being
smooth. The type retains some color, showing the shell to be choco-
late brown above with the lip white; OC. dintea Con. is figured in my
Preliminary Report, Pl. V, fig. 2, p. 52, 1886.
Conrad’s original description contains a misprint which seems to
have been perpetuated in later publications. It should read “ with
fie approximate equal impressed lines,” instead of “four . .
lines.” Type in National Museum; examples in my collection.
Pleurotoma Clarkeanan. sp. PI. 4, fig, 3.
Shell rather solid, fusiform, whorls about nine, spire smooth (?),
whorls with about eleven strongly raised and rounded ribs crossed
by coarse revolving lines ; somewhat alternate. The finer lines be-
tween often being double, especially upon the body whorl. Suture
appressed, bordered by a corded thread, and this in turn by a con-
cave space. Aperture obloug-oval. Canal short. Sinus semi-
circular, and well up in the aperture. Length 31 mm.; breadth
11 mm.
Murex (Pteronotus) Burnsiin. sp. Pl. 4, fig, 4, 4a,
Shell large, with three foliated varices, whorls nine. Nucleus
pointed, smooth ; whorls convex, appressed at suture, whorls fol-
a:
THE NAUTILUS. 99
lowing the nucleus have two ribs on centre, each rib bearing a node
which is equidistant from the foliations; three continuous fin-like
varices continued from apex, which revolve in descending, edges of
varices dentate. Body whorl with about thirteen distant spiral raised
ribs, the two on the periphery bearing a node each between the folia-
tions. Aperture elongate-oval. Outer lip having internally seven
plications, inner lip smooth ; canal rather long, almost closed pos-
teriorly, widening anteriorly, and bent upwards. Canal of preced-
ing aperture persistent. Alt. 65 mm.; diam. 33 mm.
This elegant Pteronotus is described from the unique example be-
longing to the National Museum. Named in honor of its discoverer,
Mr. F. Burns, of the U. S. National Museum.
Cerithium serratoides n, sp. Pl. 4, fig. 5.
Shell elongate ; suture linear; whorls ornamented with transverse
ribs, which are moderate near the suture, but suddenly become
enlarged and spinous at the intersection of a spiral near the middle
of each whorl ; a couple of fine spiral lines occur between the spines
and preceding whorl ; also a single spiral line just below the suture.
Whorls slightly shouldered.
Specimen figured has lost its apex and aperture, but*is so evi-
dently a serrate Cerithium that I have concluded to describe it.
Length of part figured is 36 mm.
Type in National Museum. Example in my cabinet.
Latirus indistinctusn.sp. PI. 4, fig. 6.
Shell fusiform, whorls nine, rounded; apical whorl smooth, the
remaining ones transversely ribbed, crossed by raised lines that on
the body whorl are alternately coarse and fine ; suture distinct, whorls
appressed toit anteriorly. Canal long, twisted strongly to the right
and then to the left. Striations continue to the end of canal. Ap-
erture oblong-oval, toothed posteriorly and shouldered anteriorly.
Outer lip striated internally ; inner lip covered with a thin callus,
definitely delineated and running to end of canal. No teeth on the
inner lip, but some of the striations show through the callus. Alt.
42 mm.; diam. 14 mm.
This handsome species is strongly Fusoid in appearance, and does
not possess plications on the inner lip like most of the genus, but it
evidently belongs there from its other characters.
Type in the National Museum. One example in my collection.

NOTES OF A COLLECTING TRIP TO DEPARTURE BAY, VANCOUVER
ISLAND.
BY GEORGE W. TAYLOR.
The account given by Mr. Wood in the October number of THE
Naurixus of his collecting trip to Monterey Bay tempts me to put
on record an experience of my own which goes to prove that our
Northern waters are quite as rich in molluscan life as those of the
sunnier South.
Departure Bay is a small bay on the east coast of Vancouver
Island, about 75 miles north of Victoria. It is shut in by its own
shores on the north, west, and south, and is protected from the open
sea on the east by a series of small islands. Consequently, the
water, at most seasons of the year, is smooth, and as the depth
ranges from 10 to 50 fathoms, and the bottom is varied, being sandy
in some places.and rocky in others, the bay is a capital place for a
dredging expedition.
In August, 1888, through the kindness of Mr. S. M. Robins, the
managing director of the New Vancouver Coal Company, I was
able to spend four days in dredging from a small steam launch be-
longing to the Colliery Company. Much time was wasted on this
occasion in searching for suitable ground, but the result of the four
days’ work was by no means disappointing, as I took home with me
more than five thousand (5,000) specimens of one hundred and ten
different species. One of them, since named in manuscript by Mr.
Whiteaves as Pecten Vancouverensis, was new to science, and several
others were additions to our Vancouver lists.
In July of the present year, I spent three and one-half days in
the same locality in company with Professor Macown, the well-
known Canadian botanist and naturalist. We were determined, if
possible, to beat the previous record, and therefore worked very in-
dustriously. Wespent two and one-half days collecting on shore
between tide marks, and one day was devoted to dredging over the
ground prospected in 1888.
In the shore collecting my own captures amounted to nearly
2,500 shells of 61 species. In the dredging expedition our joint bag
reached the grand total of over seven thousand (7,000) specimens of
88 species. This very satisfactory result was obtained from an ordi-
THE NAUTILUS. 101
nary open sailing boat, with a crewof three men and a single home-
made dredge. I should mention that 15 species were taken both
between tides and by dredging, so that the actual number of differ-
ent species taken in the three and one-half days was 156.
In shore collecting, no attempt was made to collect the very com-
mon shells in quantity, or the numbers might have been swelled
indefinitely. In fact, I was looking more especially for Chitons, of
which I took seven species (183 specimens), and the smaller shells,
such as Volutella pyriformis Cpr. (40 specimens), and species of
- Odostomia, which occurs commonly under rocks at low water. I
took also on this occasion a very fine series of Terebratella trans-
versa Sby., which was found literally in thousands attached to the
rocks on the south side of the bay.
Fine series of several Macomas were dug in the sand, and a few
specimens of the curious Lepton rude Whiteaves were found attached
(as is their habit) to the central segments of specimens of Cebia
pugetensis, which we dug out of the muddy shores.
When dredging, everything that came up was preserved, and the
fioer sand and mud boxed, and afterward dried and examined at
home.
Of the Pelecypoda dredged, by far the commonest specimen was
Acila Lyalli, of which at least a couple of thousand specimens were
taken. Another common bivalve was Cryptodon sericatus Cpr.,
about 300 specimens. Venericardia borealis Conrad, Nucula tenuis
Mont., and Luecina tenuisculpta Cpr., came next in order, about
100 of each being taken.
Of rarer shells may be mentioned, Pecten Vancouverensis W hiteaves
and hastatus Sby., Amusium caurinum Gould, Modiolaria laevigata
Gray and nigra Gray, Crenella decussata Mont., Cardium blandum
Gould, Fulvia modesta Ad. and Rue., Cryptodon flexuosus Mont.,
Astarte Esquimalti Baird, and undata Gould, Psephis Lordi Baird,
Clementia subdiaphana Cpr., Venus Kennerleyi Reeve, Macoma yoldi-
formis Cpr., Cuspidaria pectinata Cpr., Kennerlia filosa Cpr., ete.
Of the Gasteropoda the most abundant were, Nassa mendica Gould,
Nitidella Gouldit Cpr., Olivella bueticaCpr., Mesalia reticulata Mighels,
and the deep-water variety of Margarita pupilla Gould, of each of
which more than one hundred specimens were obtained.
Of rarer shells the following is a partial list: Dri/lia incisa Cpr.,
and cancellata Cpr., Mangilia sculpturata Dall, Cancellaria cireum-
cincta Dall, Velutina laevigata Linn., Turbonilla torquata Gould,
102 THE NAUTILUS.
chocolata Cpr., and Lordi Smith, Seala indianorum Cpr., Solariella
peramabilis Cpr., and varicosa Mighels, Puncturella galeata Gould,
cucullata Gould, and Cooperi Cpr. (all living), Cryptobranchia con-
centrica Midd., Ischnochiton interstinetus Gould, and cancellatus Sby.,
Placiphorella sinuata Cpr., Utriculus incultus Gould, and Rictaxis
punctocelata Cpr., this last being new to our Vancouver list.
I have not attempted to give a complete list, as such would take
up too much of THe Navutitus’s valuable space, and would, more-
over, be of little interest ; but I think I have written enough to show
how very abundant the Mollusca are in our seas, and how much may
be accomplished in even a single day’s collecting if one knows ex-
actly how and where to look.
A REPLY TO ‘‘SOME (RESPONSIVE) REMARKS RELATIVE T9 CYPREA
GREEGORI, FORD.”’
BY EDGAR A. SMITH.
It is flattering to see that my remarks on Mr. Ford’s so-called
species of Cyprea have been deemed worthy of such lengthy con-
sideration. It were easy to take Mr. Ford’s paragraphs seriatim,
to make sharp replies, and to confute them, but I value the pages of
THe Navritus too highly to occupy them with matter of that de-
scription. I will merely observe, then, that I have carefully recon-
sidered the subject, and I still am of opinion that Mr. Melvill’s
meaning is quite evident. It is to be regretted that Mr. Ford did
not cut the leaves of the work he was consulting and carefully ex-
amine it, for, had he done so, he could not possibly have failed to see
to which species Mr. Melvill assigned the var. coloba, and possibly he
would have adopted that name.’ When I suggested that «even
courtesy directed us to employ Mr. Melvill’s name, it occurred to
me that possibly some persons might be ignorant of or disregard the
friendly custom of adopting as a specifie name one already used in
a varictal sense by another, and the readers of THe NAUTILUS are
now in a position to judge whether my supposition was well-founded.
In conclusion [ would point out that it is hardly fair for a writer
who is criticising the work of another, unnecessarily to put in in-
verted commas phrases andl words which the general reader might
estimate as quotations. The words “state of things,” “ reminded,”
“with thanks,” do not occur among my obzervations, and the “bit
also emanates from Mr. Ford.

A LIST OF THE BRACHIOPODA, PELECYPODA, PTEROPODA, AND NUDI-
BRANCHIATA OF JAMAICA, LIVING AND FOSSIL.
COMPILED BY T. D. A. COCKERELL.
No list of the bivalve Mollusca of Jamaica has ever been pub-
lished, and many of the commonest species are unrecorded from the
island. The present compilation was prepared during the time J was
Curator of the Jamaica Museum, and is, I think, almost as complete
as the present state of knowledge will permit. But for the kindness
of Mr. H. Vendryes in permittivg me the free use of his collections
and MSS. the list could never have been prepared, and it is, in the
main, a monument of his industry, extending over a great number
of years. Mr. Vendryes informed me that the specimens recorded
by him might be regarded as correctly identified, as not only has he
given them careful study himself, but they were submitted to and
verified by Messrs. Swift and Carpenter.
All records are given as I found them, in alphabetical order
under each group; synonymy being indicated by cross references.
The solitary nudibranch at the end may serve to remind students
that there is a rich but wiknown nudibranch fauna in the seas
around Jamaica.
[Since writing the above, I have submitted the list to Mr. E. A.
Smith, who has most kindly indicated some rectifications in the
generic nomenclature, and searched some works inaccessible to me,
with the result of discovering several additional records. Mr.
Smith thinks that a thorough search through the different mono-
graphic works, and the older books, would reveal many other
records, I regret I have neither time nor opportunity to make this
search, buat Ido not think many reliable records would be found.
Mr. Smith has discovered seven records (indicated in the list
within brackets) which are certainly erroneous, and in the case of
easily-recognized species attributed by older authors to Jamaica, but
not found there since, I think we may well express some doubt.
Specimens of various kinds were frequently brought to me at the
Jamaica Museum, which I might easily have supposed Jamaican,
without careful inquiry ; such specimens would be from Colon prin-
cipally, but in former days, when Jamaica was on the highway to
the Pacific and antipodes, they might have come from more distant
104 THE NAUTILUS.
points. Undoubtedly, the marine shells of Jamaica are imperfectly
known, but the additions will be made by dredging and such means,
and will not be found in such collections as were probably examined
by the earlier writers. |

This group holds the same relation to Acanthochites that Pallo-
chiton holds to Chetopleura. It is a variation distinctly in the direc-
tion of the Cryptoplacide, recalling Choneplax, and clearly showing
the Acanthochitoid genesis of that family.
A. retrojectus n. sp.
Shell small, narrow and elongated, convex, not carinated; black
or black-brown, with a whitish “v” or three white stripes on each
valve, sometimes broadly maculated with whitish at the sides.
_ Intermediate valves moderately beaked (except valve ii, the pos-
terior margin of which is straight), sculptured with comparatively
coarse, rounded, scattered pustules, which become smaller and more
crowded toward the middle, and are lower and less distinct on the
ridge, no areas being distinctly differentiated on the valves. End

valves similarly sculptured. Posterior valve small, having the
mucro obtuse and posterior, the posterior slope short, vertical.
Interior green, marked with black in the cavity. Head valve
having the insertion plate about one-third as long as the front slope
of the tegmentum, with 5 small slits. Intermediate valves having
very oblique plates with 1-1 minute posterior slits. Posterior valve
having the insertion plate short and strongly directed forward, with
a small slit on each side. Sutural lamine rather long and narrow,
projecting far forward. Sinus wide, deep, and square.
Girdle microscopically chaffy, with a series of hyaline spicules at
the edge, and 18 small and compact silvery tufts.
Length 92; width 32 mill. (dry specimen).
Port Jackson, near Sydney. Abundant. Collected by Dr. J. C.
Cox.
GENERAL NOTES,
ALcyNA.—Specimens of the rare Aleyna ocellata A. Ad. are in-
cluded in Mr. F. Stearns’ last collection of Japanese mollusks. It
proves to have a corneous operculum, and therefore belongs to the
Trochide instead of the Phasianellide, where it has hitherto been
placed.— H. A. P.

A NEW SPECIES OF PATELLA.
BY H. A. #eEESBRY.
Patella kermadecensis n. sp.
Shell large and massive, conical, the apex subcentral; slopes of
cone nearly straight ; outline short ovate, slightly narrower in front.
Exterior whitish, apparently strongly ribbed when perfect, but the
specimens described are everywhere deeply eroded. Border lightly
scalloped by the ribbing, and finely puckered at the edge. Muscle-
scar roughened, strongly marked, and either white or bright orange ;
rest of the interior white, stained in places with livid-brown or
purplish.
Length 135, breadth 115, alt. 48 mm.
Length 111, breadth 102, alt. 45 mm.
Habitat, Kermadec Is.
The two specimens above described, of this large species of the
subgenus Scutellastra, were sent to me by Mr. E. W. Roper, of
Revere, Mass., who obtained them from the original collector. ‘The
species can be compared only with P. patriarcha Pils. from the Cape
of Good Hope, and P. mexicana Brod. & Sowb. from West Mexico.
The former of these is a wider, more angular species ; the latter is
more oblong, and has more obvious primary ribs. Figures will be
published later.
110 THE NAUTILUS.
NOTES ON COLLECTING SHELLS IN JAMAICA.
BY CHAS. T. SIMPSON.
About the first of December, Mr. John B. Henderson, Jr., of
Washington, and the writer visited the island of Jamaica for the
purpose, principally, of collecting land, fresh-water and marine mol-
lusks. We called on Mr. Henry Vindryes, a veteran collector and
conchologist in Kingston, inspecting his magnificent set of Jamaica
Shells, and receiving from him every possible courtesy and many
useful notes as to localities.
As our stay was to be limited to some three weeks, we were anx-
ious to begin work at once, to actually put our hands on some
of the land snails in their homes. We hired a cab with a good
natured darkey for a driver, and a miserable, little, bony horse, of
uncertain color, and started for the suburbs, in the direction of
Rockport with our eyes strained to catch sight of the splendid
Orthalicus undatus, which we were told we might find on our way.
The poor little horse, which wobbled about first from one side of the
road to the other asif in search of snails, but probably from sheer
exhaustion, was suddenly brought to a standstill without much
exertion by the driver, who exclaimed as he pointed his whip to
some low trees on the south of the road “Da de snail you want
massa.’ Ithink we had all observed them at the same moment, and
with a shout like boys we were out of the cab and racing across
the road, through a terrible hedge of wild pinguin in less time than it
takes to write it. There they were, great beantiful fellows, varie-
gated with ash color and glossy black, one, a half dozen, fifty, a
hundred, in fact without limit! They clung to all kinds of trees
and shrubs in the low tangled scrub, and in great numbers to the
tall cylindrical Spring Cereus; in almost every case glued by an
epiphragm so solid that it was well nigh impossible to dislodge them,
and invariably with the spire pointing downward.
When we came out of the woods an hour afterward we were as
wet with perspiration as though we had been dipped in water, and
covered with every description of sticking burrs; our flesh was
lacerated, and our hands dirty and bleeding, for everything in the
scrub bears villainous thorns. On the debtor side we had ruined
two suits of clothes, and to our credit could be placed‘ over five
hundred superb living Orthalicus. We had learned a lesson, too,
THE NAUTILUS. 1 alal
worth remembering, viz, never wear anything decent when collect-
ing in the tropics.
During our stay we drove around the entire island, visiting every
parish. Owiug tothe worthlessness of our team, the illness of the
driver, and the almost incessant rains we encountered on the north
side, our opportunities for collecting were greatly diminished.
It was only when we stopped over a day or so at the towns that
we were able to get any great amount of material. Strangely
enough we found almost no marine species whatever. Occasionally
on the rocky beaches we obtained Neritina virginea, a few Littorinas,
Tectarius and Neritinas, but for miles, in fact along whole parishes,
though the road ran near to the sea, and we watched closely, not
even a valve was seen.
The lack of marine forms was made up in the abundance of the
land snails, and in some cases the fresh water species. In a branch
of the delta of Roaring River, under a great breadfruit tree, H.
picked up a dead Hemisinus lineolatus. Then I looked on the rocky
and sandy bottom and found it alive by handfulls, and we met with
it in quantities elsewhere.
We kept an eager watch for the great white Helix aspera. My
friend picked up asingle dead specimen on the road near Falmouth,
and this fairly turned our heads. We inquired of every darkey
from that on, hearing of it often like the Ignis fatutis, just a little
way out of reach. Near Montego Bay we got afew more dead
ones, and again as it was growing dark we discovered a dozen or so
on the bushes and vines when we were nearing Savanna la Mar.
The next day I started out early fora walk, resolved to find this
snail if thorough search would do it. I tramped the whole forenoon
and got only a few Ampullarias, and two o’olock found me tired,
hungry, and thoroughly disgusted, seven miles from our hotel, and
uncertain whether to push on to some low hills a mile ahead, or to
give it up and go back. My resolve determined me and I went on.
The first rounded knoll Jooked well at a little distance—one learns
in a short time to distinguish good from poor localities a long way
off. The elevation did not occupy more than half an acre; red clay
with decomposed limestone. It was originally a dwarf scrub which
had been partly cleaved a couple of weeks before. The first thing
I saw was a fine dead Helix aspera on the ground, then others, there
they lay thickly‘ all around me, bright and fresh, with the animals
nicely cleared out by tropic showers, the sun, and swarming insects,
Tt? THE NAUTILUS.
I hardly dared move for fear of stepping on them, and to calm my
excitement, and assure myself that it was not all a wild concholo-
gist’s dream, I stood still and tried to count a hundred, but when I
had got to twenty I saw half a dozen live ones clinging like a string
of enormous white beads to a little shrub right beside me, and I
quit counting and gathered them in. Then I sat down and without
moving I picked up thirty fresh, cabinet specimens. About that
time it just began to dawn on me that the great Lucerna acuta was
as abundant as the aspera, and in no time I had my hands full of
the fine, big, brown fellows. Afterward I got me eyes focussed down
to seeing Sagdas, Helix sinuata, three or four Cylindrellas and as
many Tudoras, and that under the leaves. and among rubbish there
were quantities of small Glandinas, Zonites and Microphysas, that
the ground when closely examined was literally bespangled with
lovely little Proserpinas, that shone in the sun like polished opals.
To my dying day I never expect again to see such collecting
unless I revisit Jamaica. Hunger, fatigue, headache, the flight of
time were forgotten, and I was only warned that I must return by
the fact that the sun was nearly down before I knew it, and that I
had an eight mile walk and darkness before me. On a little spot
no larger than a city lot, I had taken in a few hours over thirty
species of land shells. AsI reluctantly tore myself away I took
fifteen asperas from a small Mango, and on the border of the clear-
ing where some one had bent together a couple of young logwood
trees, not as large as my wrist, I picked twenty-five more fully adult.
and one young one.
Shall I tell how in a narrow limestone gorge arth Rio Cobre near
Bogwalk in the talus under a ledge some two rods long we found
no less than forty-five species, all living, and nearly every specimen
in perfect condition ; or how at Mandeville the honey-combed rocks
were crowded with lovely Choanopomas, rough as chestnut burrs,
now H. wild with excitement and regardless of bats, centipedes,
scorpions, and poisonous vines wedged himself into a dark cave
whose mouth was at least two sizes too small for his body ; how he
stuck fast, and alone and far from help, could neither get forward
or backward for awhile, how he pushed on to be rewarded by find-
ing quantities of Helix peracutissima and the great purple H. jamai-
censis, the latter clinging to each other on the roof like so many
stalactites, a snail which, by the way, we had repeatedly been told
was extinct! I fear it may be now.
THE NAUTILUS. 1138
It is enough to say that for the brief time and limited opportuni-
ties we had, our trip was a success, and we left with many regrets
that we could not spend the rest of the winter on the island, and
thoroughly explore it, and collect its inexhaustible treasures.

NOTICES OF NEW CHITONS, II. -
BY H. A. PIBBBRY.
Chiton Cozi, n. sp.
Shell oblong, much elevated, carinated ; delicate bluish mottled
or blotched with olive-brown, yellow and white; girdle delicate
blue-green, with narrow white bars. Sculpture as in Ch. jugosus
Gld., but grooves of the pleura shorter, straighter, narrower, and
more spaced. Girdle-scales convex, shining, microscopically and —
superficially striated, each measuring about .80 mm. wide. Length
13, breadth 73 mm.; divergence, 90 to 110°.
Port Jackson (Dr. J. C. Cox!)
This is probably the Lophyrus jugosus of Angas’ Port Jackson
Catalogue, P. Z.S. 1867. It differs from Goulds’ species in the
totally diverse color-pattern, etc.
Acanthochites granostriatus n. sp.
Elongated, the tegmentum occupying about one third the total
width in dry specimens. Valves obtusely keeled, the dorsal ridge’
indistiently clouded with whitish, orange and biackish; side mot-
tled in varied patterns with olive and white. Girdle olive, the 18
tufts silvery stained with blue or dirty olive.
Valves distinctly imbricating ; the dorsal areas rather wide, con-
vex, distinct but not raised at the edges, having numerous rather
weak longitudinal striz. Side areas having elevated pustules
arranged radially and connected by opaque lines giving the aspect
of radial striz. Tegmentum of post. v. subcircular, the mucro
rather acute and elevated, at the posterior third. Length 9, breadth
32mm. Port Jackson and Port Hacking, N.S. Wales (Dr. J. C.
Cox !)
Acanthochites Coxi, n. sp.
Valves grayish, somewhat mottled with olive and fleshy, the dor-
sal areas dark red or marked with olivaceous. Girdle olivaceous.
Valves nearly disconnected by spiculose bridges of girdle tissue at
the sutures. Dorsal areas longitudinally striate; sides sculptured
_ with convex pustules elongated radially. Tegmentum of posterior
_ valve subcircular, slightly wider than long, the rather elevated,
_ acute mucro slightly bebind the middle. Interior rose colored.
120 THE NAUTILUS.
Girdle densely clothed with short, hyaline spicules, the tufts repre-
sented by inconspicuous clumps of slightly longer spines. Length
23, breadth 13 mm.
Port Jackson, N.S. Wales, (Dr. J. C. Cox !)
Acanthochites Matthewsi Bednall & Pilsbry.

SHELL COLLECTING IN NORTHERN ALABAMA.
BY H. E. SARGENT, WOODVILLE, ALA.
Huntsville, Alabama., the county seat of Madison County, is a
somewhat exceptional southern city in that it has an abundant supply
of pure spring water bursting forth from its very foundations. This
spring of sparkling lime water, beside supplying the city mains,
attords a constant stream several feet in width and _ several
inches in depth to go to waste. In this stream and also in the reser-
voir I have, upon several occasions, taken large numbers of Gonio-
basis nassula Con., var. perstriata Lea. A recent visit, however,
disclosed the fact that although still plentiful in the reservoir, this
interesting species has almost disappeared from the stream. A flock
of geese near by offered a possible solution of the mystery.
Upon this occasion, a more careful search was made than upon
former visits, with very satisfactory results. The upper surfaces of
the rocks were found to be covered with a species of Ammicola
which the Editor refers to a form previously had from Florida, and
for which he proposes the name of Ammicola olivacea Pils. In more
secluded spots, several specimens of Plewrocera brumbyi Lea were
also taken. These specimens were much larger than those found in
other streams in this vicinity. A hand-dredge brought from the
oozy bottom numerous beautiful clear specimens of Pisidiwm sp.
Physa halei Lea and Limnaea desidiosa Say were found in consider-
able numbers. A single young specimen of Planor bis trivolvis Say,
and a single valve of Sphaerium indicated their presence, although
no good specimens were taken. Several dead specimens of Cam-
peloma coarctatum Lea also came to light.

A two-hour hunt for Helix carolinensis, made December 1, upon
the timbered flats of the Paint Rock River, resulted as follows:
Helix obstricta Say, var. 4. Binn = H. carolinensis Lea, 59. H.

A little later in the season, these flats will be inundated most of the
time for several months. <A visit to the same station a little earlier
than this last year, yielded about the same results.
NOTES ON SOME NEW ZEALAND LAND AND FRESH WATER MOLLUSKS.
BY HENRY SUTER.
1. Ancylus woodst Johnston. Aboutone year ago, I discovered a
small Ancylus in the River Avon, near Christchurch, which I
recognized as being identical with A. woodsi from Tasmania. This
was, to my knowledge, the first Ancylus ever found in New Zealand,
and I mentioned the fact in Crosse’s Journ. de Conch., vol. 32, p.
248. I can not recognize Ancylus dohrnianus Clessin as a New
Zealand species, as long as Clessin can not give the exact locality
where his species has been found, and thus enable us to verify its
occurrence in this colony. There is no such Ancylus known to New
Zealand conchologists, and it therefore will only help to swell the
already large list of shells erroneously ascribed to New Zealand.
Only a few weeks ago, I collected a good number of A. woodst,
and this time alive. To my great astonishment I found several
specimens with a septum more or less in process of formation, so
that there could be no doubt but that this mollusk is not an Ancylus
at all, but a Gundlachia. This was further confirmed by examin-
ing the radula, which perfectly corresponds with the radula of a
Gundlachia collected and kindly sent to me by my friend, Dr. V.
Sterki, of New Philadelphia, Ohio. Having come into possession of
some literature on Tasmanian mollusks, I now find that Johnston, in
his description of A. woodsi (Proce. Roy. Soe. Tasm., 1878, page 25)
says: “Animal and teeth almost similar to Gundlachia pelterdi.”
And in the description of G. petterdi (1. ¢. page 23) he writes: “ In
the young state the shell is simple, and resembles the common Ancy-
lus.” I really do not understand why Johnston established the n. sp.
A. woodsi, when he must have been fully aware of the fact that it
ia
THE NAUTILUS. 123
was a young Gundlachia! In his list of Tasmanian mollusca, 1890,
he simply drops his A. woodsi without mentioning that it is a
young Gundlachia. I have not yet found full-grown specimens of
our Gundlachia, but I hope to succeed later on, and it is to be ex-
pected to be a similar form to G. petterdi Johnston.
Prof. Hutton suggested to me that this Gundlachia might, per-
haps, have been introduced from Tasmania on aquatic plants, which
were used in packing trout ova, and as our fish-hatching ponds are
in communication with the river Avon, there is all possibility of
this being really the case. However, there is one objection. Up to
the present day I found our Gundlachia only on aquatic plants in
the lower parts of the river, from the outflow of Horseshoe Lake to
New Brighton, but not upward between this outflow and the fish-
hatching ponds. ‘This makes it very likely that Gundlachia occurs
in the swampy Horseshoe Lake, difficult of access, and was washed
down in the river Avon when the canal was cleared from Anacharis
weeds. If this mollusk is really indigenous, it will, no doubt, be
found in ijocalities where the introduction from Tasmania is out of
question, but as long as this is not the case, we must remain doubt-
ful on this point.
In the “ Reference List” I published with my friend Mr. Ch.
Hedley, of Sydney (Proc. Linn. Sve. N.S. W., vol. VII (2) p. 624),
he put down Ancylus tasmanicus Tenison- Woods, as being synonymous
with A. woodsi. This is wrong, as the former is quite different, and
I believe it to be really an Ancylus. A. australicus Tate and A.
smithi Cox are very likely also young forms of Gundlachia. A.
assimilis Pett. and A. oblonga Pett. [have notseen. It would be of
highest interest to examine the dentition of the Caledonian A. reti-
culatus Gassies and A. noumeensis Crosse, which Mr. Hedley thinks
to be nearly allied to the so-called A. woodsi.
2. Rhytida meesoni Suter (Reference List, ]. c. page 631) is no
Rhytida, but a Paryphanta, as the animal lays calcareous eggs,
whilst the genus Rhytida is considered to be viviparous. The genera
Paryphanta and Rhytida are in the shells, the exterior of the ani-
mals and the radula so nearly allied, that it is not always easy to
separate them. Very likely the genital organs will show generic
differences, and it is my intention to study the anatomy of these
genera as soon as opportunity offers and time permits.
3. Thalassohelix ziczac Gould. There was always some doubt
whether this shell was really a New Zealand species or not, and at
124 THE NAUTILUS.
the request of Mr. Hedley, when we worked out our “ Reference
List,” I tried to solve the question. I came to the conclusion that
Th. portia Gray must be the same species, and therefore they appear
as synonyms in our list. I then selected two perfectly similar speci-
mens, and sent one to Mr. Edg. A. Smith of the Brit. Museum for
comparing it with Gray’s type of H. portia, the other to Dr. Dall,
Washington, to compare it with Gould’s type of Hl. ziczac. Both
gentlemen very kindly acceded to my request, and I herewith wish
to express my gratitude to them.
Mr. Edg. A. Smith writes: “Hellz portia Gray. Right, but I
doubt if Gould’s ziczac is the same species.” And Dr. Dall reports:
“There is no doubt whatever of the identity of your shell with
Gould’s type. He, in his preliminary report (Otia Conch., p. 17),
refers it to New South Wales, but in his final report (Moll. U.S.
Expl. Exp., p. 41), he says that it was collected by Dr. Pickering
in a crater at Taiamea, New Zealand. His type was a little faded,
hence the prominence of the dark variable lines and the straw color
of the shell.’ These reports set all doubts at rest.
4. Thalassohelix zelandie Gray. In a letter to me, Mr. H. A.
Pilsbry expressed his opinion that the shell Prof. Hutton and I con-
sidered to be Gray’s Hel. zelandiw might, perhaps, be another spe-
cies. I therefore forwarded a specimen to Mr. Edg. A. Smith, and
he kindly compared it with Gray’s types. His opinion is as fol-
lows: “‘ The shell under this name is, I think, a form of that species.
It is larger than any of our typical examples and more brightly
variegated, and the whorls are perhaps, a trifle flatter, still I think
it is only a variety.” To this I would remark that most species of
Thalassohelix are subject to great variation, and I am confident that
we identify the right shell as Th. zelandie Gray.
5. Endodonta varicosa Pfeiffer, I considered to be synonymous
witb E. timandra Hutton (Reference List, |. ¢., p. 651). Mr. H. A.
Pilsbry, however, denies their identity (Man. Conch. (2) VIII, p.
84), and I therefore also sent specimens of E. timandra to Mr. Edg.
A. Smith for comparing them with varicosa Pfr. He kindly sent me
the following information: ‘“ E. timandra Hutt. This is distinct
from varicosa Pf. It is smaller, more openly umbilicated, has more
riblets, and the armature of the mouth is different. There are three
teeth in timandra and one (overlooked by Pfeiffer and Reeve) in
varicosa, situated on the body-whorl. It is a very slender lamella,
and might easily be overlooked.” After receiving this report, I
THE NAUTILUS. 125
looked all specimens of EF. timandra in my collection carefully
through, and had the great satisfaction to find a few specimens of FE.
varicosa Pf. The two species differ in the characters mentioned by
Edg. A. Smith; however, I have one specimen of LE. varicosa with
two lamellae in the body-whorl. If not very carefully examined,
the two species may very easily be confounded. It seems that LE.
timandra occurs only on the North Island, while E. varicosa seems
to be limited to South Island.
6. Charopa sylvia Hutton. I thought this species to be identical
with Ch. tau Pfeiffer (Ref. List., |. ¢., p. 657), but felt always more
or less doubtful. I therefore sent specimens with the others to Mr.
Edg. A. Smith, and he very kindly wrote to me: “ CA”. sylvia Hutt.
You question this being the same as Hel.tau Pfr. We have not yet
the latter in the Museum, but Pfeiffer’s description of the sculpture
‘subdistantum costato-plicata’ scarcely applies to your specimens.
They are undoubtedly identical with Pieiffer’s Hel. gamma. Ihave
compared them with the types, and they agree in every respect, ex-
cepting that yours are fresher.” Therefore :
Charopa buccinella Reeve, sp., 1852 (=gamma Pfeiffer, 1852
(? 1853) == sylvia Hutton, 1883).
Now it remains to identify Ch. taw Pfr. It may be that my
Charopa mutabilis is this species ; I have sent a specimen to Vienna
to have it compared with Pfeiffer’s type, and am awaiting a report.

SHELLS OF THE SAGINAW VALLEY, MICHIGAN.
BY BRYANT WALKER, DETROIT, MICHIGAN.
Some twenty-five years ago the late Dr. George A. Lathrop,
while residing at East Saginaw in this State, made a considerable
collection of the shells, which he found in that vicinity.
After lying packed away for many years, the collection has recently
come into my possession, and as it contains some material of consider-
able interest, and no local catalogue from that part of the State has
ever been published, the following list of the species represented
has been deemed worthy of a permanent record.
I am indebted to Dr. V.Sterki for the determination of the Pupi-
'- de and to Mr. A. A. Hinkley for the identification of Goniobasis
126 THE NAUTILUS.
semicarinata Say and depygis Say. Unless otherwise specified the
locality is in all cases East Saginaw.
Selenites concavus Say.
Zonites nitidus Mull. Zonites indentatus Say.
Zonites arboreus Say. Zonites minusculus Binn.
Zonites radiatulus Alder. Zonites fulvus Dr.
Zonites multidentatus Say. Heretofore cited only from the western
part of the State.
Patula alternata Say.
Patula perspectiva Say.
Patula striatella Anth.
Patuia lineata Say.
Punctum pygmzeum minutissimum Lea.
Helix multilineata Say.
Helix thyroides Say.
Helix albolabris Say. Above the average in size and one example
an almost perfect albino.
Helix albolabris dentata.
Helix exoleta Binn.
Helix sayii Binu. Port Austin. A new locality for this (in Mich-
igan) rare species. |
Helix mondon fraterna Say.
Helix leaii Ward.
Helix tridentata Say.
Helix palliata Say.
Helix virgata Da Costa. A single well marked example of this
species, apparently of the variety called “alba” by Taylor, occurs
in the collection with the following label: “From Dr. Clark of
Flint, Michigan, where he says it was found.” Dr. Clark wasa
well known physician of Flint in times past; but as both he and
Dr. Lathrop are dead, it is not probable that any further informa-
tion in regard to the circumstances under which this shell was
found can be had. ‘The specimen though mature, is not quite fresh,
and as the body whorl was filled with hard packed fine sand it
seems very probable that it was imported in the earth about some
foreign plants.
Vallonia pulchella Mull. Determined by Dr Sterki.
Strobilops labyrinthica Say.
Pupa corticaria Say. These are the first specimens seen from the
eastern part of the State.
THE NAUTILUS. Tar
Pupa armifera Say.
Pupa contracta Say.
Vertigo ovata Say.
Vertigo gouldii Binn. Quite abundant apparently, and exhibiting
some considerable variation in size. A single albino example is
included, of which Dr. Sterki writes “This is a very interesting
and valuable specimen ; the only true albino among many thousand
specimens of our Vertigos I have seen.”
Vertigo ventricosa elatior Sterki. Not heretofore known from
Michigan.
Vertigo pentodon Say. Vertigo curvidens Gld.
Ferussacia subcylindrica L. |
Succinea oblivua Say. Suecinea peoriensis Wolf.
Succinea avara Say. Succinea sp.
Succinea ovalis Gld. Succinea sp.
There are four forms of Succinea in the collection, which group
around S. ovalis Gld. as a type. ‘The first is the form usually called
ovalis characterized by the short; rather blunt spire, elongated body
whorl and effuse aperture. The second is the peoriensis of Wolf, a
very widely extended form in Michigan and easily separated from
the “ovalis” by reason of the shorter body whorl and more nearly
oval aperture, which though somewhat narrowed posteriorly lacks
the patulous expansion anteriorly so characteristic of the former.
The third resembles ovalis in the shape of the aperture, but is a
more slender shell and has the spire more elongated than either the
preceeding forms. It appears to range generally over the State and
is the same form noticed as “S. higginsi Bld.” in my catalogue of
Michigan shells (Naur. VI, p. 19).
The fourth form is quite remarkable. Having the general shape,
characteristic of the group, it far exceeds them all in dimensions,
equalling in length a good sized S. obliqua Say. These shells were
labeled by Dr. Lathrop as “S. si/limani Bld.?” They agree sub-
stantially in form and size with figures of that species given by
Binney. Some individuals, however, have the spire more produced,
resembling in that respect the figures of S. hawkinsi Bd.; but the
suture is not impressed to the extent represented in that species.
None of them have the blunt apex, which seems to be characteristic
of S. haydeni W. G. Binn., though fully equalling that species in
size. Cockerell (Naur. VI, pp. 23 and 29) refers all these forms to
the S. elegans Risso of Europe. It is possible that these specimens
128 THE NAUTILUS.
are similar to the Canadian examples, which he refers to that spe-
cies.
Carychium exiguum Say.
Limneea stagnalis L.
Limneea catascopium Say.
Two forms of this species are represented in the collection. One
from the Saginaw River is of the usual form, but of unusual size,
one example being nearly one and one-fourth inches in length.
The other form from Saginaw Bay is characterized by its greatly
inflated body whorl and very short, rapidly acuminating spire. <A
single specimen from Lake Huron represents the form usually found
in the Great Lakes.
Limneea reflexa Say. Bayou, East Saginaw and Saginaw Bay.
The latter somewhat smaller and more slender than the former.
Limnezea reflexa scalaris. Intermediate between the type and the
variety.
Limnea palustris Mull. Larger than the average in size. The
striped variety corresponding to form of ZL. reflexa known as zebra
Tryon, is also represented.
Limneza cubensis Pfr.
Physa ancillaria Say. Saginaw Bay.
Physa sayil Tapp.
Physa gyrina hildrethiana Lea.
Aplexa hypnorum L.
Planorbis trivolvis Say.
Planorbis bicarinatus Say.
Planorbis campanulatus Say.
Planorbis albus Mull.
Planorbis exacutus Say.
Planorbis parvus Say. Among a number of the usual form of this
species occurs one of the curiously distorted examples, in which the
whorls almost from the apex are entirely detached from each other
and coiled obliquely like a ram’s horn.
Segmentina armigera Say.
Ancylus fuscus Ad. Saginaw River.
Ancylus parallelus Hald. Saginaw River. Much narrower and
with the sides more flattened and hence more nearly parallel than
in specimens from other localities.
Lyogyrus pupoidea Gld. Heretofore this species has been cited
only from the western part of the State.
THE NAUTILUS. 129
Campeloma decisa Say. Cass River.
Amnicola porata Say.
Bythinella obtusa Lea.
Goniobasis livescens Mke. Saginaw Bay.
Goniobasis semicarinata Say. Saginaw River.
This is the first time this species has been cited from this State.
Goniobasis depygis Say. Saginaw River.
This species, although cited in the earlier lists of Sager and Miles,
has not been found by any of the more recent collectors.
Goniobasis milesii Lea. Cass River.
Two specimens “from Dr. Miles,” which seem to justify Tryon’s
doubt as to whether the species is more than a globose form of G.
livescens Mke.
Unio alatus Say. Saginaw River.
Unio asperimus Lea. Saginaw River. This is the first recorded
occurrance of this species in the eastern part of the State. It may
be of interest to add that Dr. W. H. DeCamp of Grand Rapids
informs us that the species has also been recently found in the Grand
River, sothat the doubt formerly cast upon its occurrence in Michi-
gan must be considered as entirely removed.
Unio cornutus Bar. Another addition to the fauna of the eastern
part of the State. One example, probably a female, is unusually
elongated.
Unio ellipsis Lea. This and all the following species are from Sag-
inaw River.

Some FinaL REMARKS RELATIVE TO CYPRHA GREEGORI, ForD.
—Since Mr. Smith has, in the January number of the Nauri.us,
deemed it expedient to make a purely scientific subject, the vehicle
of remarks chiefly personal in character, it is just possible that com-
ment is uncalled for from me. It might be prudent, however, to
notice one or two of the gentleman’s statements, especially that
touching the ease with which he could take Mr. Ford’s paragraphs
seriatum, and confute them, etc. In respect to this show of confi-
dence, I have nothing to suggest beyond referring him to the follow-
ing not very classic, but rather trite saying, viz.: “The man who is
always sure that he could have managed things better had be been
there, is usually the one who never gets there.”
Regarding the quoted phrases so pathetically alluded to by the
gentleman, ] cannot believe that any reader save himself ever sup-
posed they were presented as parts of his communication.
Certainly such a thought never occurred to me. The “inverted
commas” were added to them simply as evidence of their general
use. Was this fact apparent to Mr. Smith? Perhaps not, and yet
—Perhaps.
As my reasons for claiming priority for the name C. Greegort were
fully explained in the Nauriius for Nov., 1895—and as the justice
of this claim has been heartily conceded by very many of our ablest

The foregoing are the titles of recent papers on Mollusca by Dr.
Stearns published in the proceedings of the U. 8. National Museum,
in Volume XVI, which includes the various articles for the year
1895. The first of the above, is an annotated catalogue of the shells
collected by the Eclipse Expedition so-called, that went to the west
coast of Africa for the purpose of observing the total eclipse of the
sun, that occurred on the 22nd of December 1889. The Natural
History work was of course incidental; itincludes also the forms
collected at the Azores, where the Pensacola touched on her way.
The total number of molluscan species coliected foots up 120, the
greater portion, over one hundred, at various African points, Ascen-
sion Island and Cape de Verde, ete. Several of the species are
shown to have a wide distribution, from the Gulf of Mexico and the
Caribbean waters to the African region ; and Trochatella radians “not
before reported outside of Peru and Chili,” was detected, a single
example, at Cape de Verde; many other forms have nearly as wide
a range.
The second paper embraces several forms, some of which were
preliminarily described in ‘The Naurimius” in May, 1895. Many

species of a decided Polynesian aspect are reported from the Gulf of
California region; among these are Chicoreus palmarose mexicana,
Ranella cruentata, Purpura hippocastanum, Casmaria vibex and
Luponia isabella mexicana. ‘This paper includes also revised de-
scriptions of species previously described by the author, notably,
Dolabella californica, Onchidella binneyi= O. carpenteri Stearns not
Binney, etc. A newspecies of Tectarius, T. atyphus, the first of this
group detected on the West Coast is described ; it occurs at Manta
on the coast of Ecuador. Other species are referred to and com-
mented upon.
The last of the foregoing titles relates to a paper hitherto briefly
noticed in “ The Nautitus,”’ (December, 1893). This includes a
list of Galapagos shells, compiled from the collections made by the
Albatross, Dr. Habel, Dr. Wolf, the Petrel, Dr. W. H. Jones and
the papers and publications of Carpenter, Albers, E. A. Smith,
Wimmer, Ancey, Reibisch, Dall, etc., ete. The Albatross collectors
obtained 109 species and several varieties; of these 59 were not
before reported as occurring at the Galapagos. A few new species
were detected and are described by the author. The total as shown
in the summarized list is 288 species and 30 varieties.
The land shells are of a distinctly West American type, compar-
~able with Chilean and Peruvian forms, and with the exception of
half a dozen local species, the marine forms are West American—
with a slight color of Caribbean or Antillean types.
Nores on Recent Co.tuectrions or N. A. MoLuusks, ETC., by
R. E. C. Stearns (Proc. U. 8. Nat. Mus. 1893). Dr. Stearns records
numerous new localities for various land and fresh-water shells, dis-
cussing particularly the range of Patula strigosa Hemphilli, and its
occurrence in Arizona at Coon Mountain, that problematic crater.
Triodopsis Levettei is reported from Fort Huachuca and Tucson
Arizona (a large form). Ft. Huachuca is so near the Mexican
boundary that Stearns believes both P. hemphilli and T. Levetter
will eventually be found in the Mexican state Sonora. Helicina
orbiculata was collected by Mr. V. Bailey near Marble Cave, Stone
Co., Mo., probably near its northern limit. Attention is called to
the discontinuous distribution of the section Mesodon, which is repre-
sented by several western species, among them townsendiana and
ptychophora; records of North Dakota and eastern Montana locali-
ties for Mesodon are still lacking. In this tract multilineata and
thyroides are to be expected, we think, but suitable stations are not
very numerous west of Minnesota and Iowa.

THE CALIFORNIAN SPECIES OF THE GENUS NUTTALLINA.
BY W. J. -RAYMOND, OAKLAND, CALIFORNIA.
In the Manual of Conchology, Vol. 14, p. 280, after directing
attention to the differences existing between Nuttallina californica
Nutt. and N. scabra Rve., Mr. Pilsbry remarks that data are desir-
able concerning the areas of distribution of the two species along
the Californian coast, especially between San Diego and Point Piedras
Blancas, near San Simeon. Having collected numerous specimens
of this genus at various points between Bolinas and Santa Barbara,
I can offer the following notes.
A glance at a map ofthe West Coast will recall certain geograph-
ical features bearing upon the distribution of marine life. Going
southward from San Francisco, the coast line which has followed a
general southeasterly direction, bends abruptly to the east at Point
Concepcion. Asa result of this, the great ocean current from the
north which has held to a course near the coast and parallel with it,
all the way from Alaska, leaves it for the first time and flowing
southward, is still further deflexed by the chain of the Santa
Barbara islands. From Point Concepcion eastward, the ocean is
warmer and the other conditions surrounding marine life are such
as to warrant the expectation of an assemblage of species, different
from those found north of the cape. While many species of mollusks
are common to our whole Californian coast, Terebra simplex, Drillia
hemphilli, Marginella varia, Cypraea spadicea, Trivia solandri, Tur-
ritella cooperi, Norrisia norrisii, Trophon belchert, T. triangulatus,
Periploma planiuscula and Barbatia gradata are species of a more
southern fauna, found in Santa Barbara county, which do not as far
134 THE NAUTILUS.
as we know pass Point Concepcion. Many other examples might
be noted.
This is not the place to enter into a discussion of the West Coast
marine faunal provinces. But it is interesting to note that as far as
the material at hand gives evidence, the two West Coast species of
Nuttallina are sharply divided by this natural boundary. At Carpin-
teria, ten miles east of Santa Barbara and at points west of that town,
to Santa Anita, within ten miles of Point Concepcion, the specimens
are uniformly JV. scabra, as are also the more southernexa mples of
the genus. Specimens collected at Point Sal, thirty-five miles north-
ward from Point Concepcion, together with those collected at San
Simeon, at Monterey, at Purissima and at points near San Fran-
cisco are uniformly N. californica. No intregrading forms were
observed. While the external appearance is not always a sure
guide to specific position, disarticulation of the plates has, in all
cases examined, revealed the species with certainty.
A study of numerous specimens from the localities mentioned,
shows the following differential characteristics, in addition to those
cited by Mr. Pilsbry. Whether they would hold good in specimens
from other localities or not, I do not know. In color WN. seabra is
externally more varied than WN. californica. Specimens of the former
from Santa Barbara are clouded and mottled with greenish upon a
buff ground-tint, on the second, third, fifth and sixth valves. The
remaining valves are much darker and less variegated. In single
valves of scabra, viewed from above, the broad curving outline of
the tegmentum on each side is bordered by a small spot of brown,
placed centrally on the light blue surface of the sutural plates. This
feature is constant in all of the specimens examined. In UW. cali-
fornica the spots are wholly absent, or in some cases replaced by in-
distinct clouds of a color darker than the surface of the sutural
plates. Of course no one would separate the species because of these
slight color differences, but taken in conjunction with the weightier
points of difference furnished by the shape of the plates, sculpture
and character of the girdle, they are interesting as showing how far
these geographical races have become differentiated from the parent
stock.

1 The present list is the first essay toward a knowledge of the snail fauna of
western Pennsylvania.
The region is an interesting one, combining the features
of the Atlantic slope and the Ohio valley; and it is desirable to have a complete
and accurate catalogue of the fauna.
The fresh-water fauna will prove especially
interesting, as we know little of the range of the Ohio River types of Unionidz
and Strepomatidz in the headwaters of that river system.—Ep. NAUTILUS.

A NEW PAPUINA.
BY CHARLES HEDLEY, SYDNEY, AUSTRALIA.
Papuina cerea Hedley.
Shell thin, translucent; contour trochoidal, color waxen white,
becoming, yellowish on the 3rd and 4th whorls, encircled below
the suture by an opaque white thread, nowhere are translucent lines
or spaces visible. Sculpture: surface of
a waxen polish; transverse growth
lines can be detected by the unaided
eye, and spiral grooves, almost effaced
above but plainer on the base, may be
deciphered with a lens. Whorls 53, flattened, regularly increasing,
the last constituting five-eighths of the shell’s height, angled at the
periphery, descending considerably and abruptly at the aperture,
gibbous at the point of flexure. Suture impressed. - Aperture very
oblique, anterior margin waved ; columella oblique, wide, extending
nearly to the angle of the aperture, subtruncate below. A thin, trans-
lucent, shining callus extends over the imperforate axis to the inser-
tion of the anterior margin of the lip.
Height 133, major. diam. 16, min. diam. 14 mm.

ON THE SPECIES OF MACTRA FROM CALIFORNIA.
BY WM. H. DALL.
In revising the Tertiary Mactracea of the southeastern United
States, it became necessary to examine the recent species and work
THE NAUTILUS. Loe
up theirsynonymy. The species of the Pacific coast especially have
long been known to be in a very bad state as regards nomenclature,
ete. Several long known forms appear, on investigation, to be
really nameless, the titles belonging to other less conspicuous spe-
cies having been applied to them, while some of the earliest named
forms have been lost sight of. I hope to furnish the Nauriius,
shortly, with synonymic lists of the east and west coast Mactras,
pending the completion of which the following descriptions are
offered.
Mactra catilliformis Conrad. PI. V, fig. 3.
Shell large, thin, whitish or straw color, irregularly concentric-
ally striated, with a gray, wrinkled epidermis, inflated short-oval
subequilateral valves and closely adjacent inconspicuous beaks ;
anterior end of shell evenly rounded in front, a little shorter than
the posterior end; lunule narrow, impressed, escutcheon narrow,
longer, rather obscure; posterior end of valves rounded, slightly
compressed and with a narrow gape when closed; hinge resembling
that of M. polynyma Stm., but more concentrated, cartilage pit
large, rather produced; posterior muscular impression larger, pall-
ial sinus rather large, rounded in front. There is a faint posterior
flexure of the valves and a feebly marked area above it, on which
the epidermis is more conspicuous. Lon. 1080, alt. 87:0, diameter
45:0 mm., in a moderately sized pair, but the adult reaches 140°0
mm. in length.
Distribution: Neeah Bay to San Diego, Cala.
This is Standella californica Carpenter, but not of Conrad or
Deshayes. It was imperfectly described without a figure by Conrad
in the Am. Journ. Conch. vol. iii, p. 193, 1867, and erroneously
stated to come from Panama. WM. lenticularis, Gabb, 1866, from the
Miocene of California is closely related.
Mactra Hemphillii n.s. Pl. V, fig. 2.
Shell large, thin, inflated, subequilateral, creamy white with a yel-
low thin epidermis, which over the body of the shell in young shells
is beautifully evenly concentrically striated and on the posterior
dorsal area is irregularly wrinkled, with an elevated raphe of epider-
mis at the margin of the area; beaks rather prominent, the ante-
rior end of the valves longer than the posterior; posterior dorsal
slope excavated; lunule obscure, eseutcheon marked by prominent
elevated radial lines of epidermis; the dorsal margin pouting in
front of the ligament, the posterior slope convex, the posterior flexure
138 THE NAUTILUS,
faint, but marked by a recession of the ventral border of the valves,
which gape but very little and not at all in front; anterior end
rounded, but smaller than the posterior; ventral border arcuate;
hinge and pallial sinus much as in the last species, except that the
sinus is somewhat smaller and less depressed. Lon. 120, alt. 93,
diam. 50 mm.
Distribution : San Diego, Hemphill and Cooper.
This fine and perfectly distinct species appears rare and I have
seen but two specimens, both from San Diego.
The preceding species belong to the subgenus Standella as
adopted by H. and A. Adams, but the following is a true Mactra,
with the ligament separated from the cartilage pit by a shelly plate.
Mactra dolabriformis Conrad, 1867, PI. V. fig. 1.
Shell much compressed, polished white under a dull brown epi-
dermis, subequilateral with inconspicuous beaks. It closely resem-
bles I. faleata Gould (from type) but has higher beaks more cen-
trally set, the anterior end more attenuated and less truncate, the
left anterior lateral tooth single and distally more prominent; the
left cardinal larger and wider ; the posterior adductor scar horizon-
tally elongate and smaller. Lon. 90, alt. 63, diam. 26 mm.
Distribution: San Diego, Cala. to Guaymas, Mexico; “ Panama”
Conrad.
This remarkably handsome shell has not unnaturally long been
confounded with M. falcata, from which the hinge separates it sub-
generically.
The true M. californica of Conrad is a Mactrinula and can at
once be recognized by its sulcate beaks. It reaches 36 mm. in
length. The M. planulata is also a small species, resembling M.
polynyma in miniature. The northern form generally referred to
M. falcata is a barely separable variety of M. polynyma which may
take the name of Alaskana.

been disarticulated. In some features it recalls the Acanthochitide.
The single species was described and illustrated from the unique
type in the British Museum, in the Manual of Conchology, vol. XIV.
DESCRIPTIVE NOTES ON CERTAIN FORMS OF POLYGYRA.
BY H. A. PIGSERY.
The genus Polygyra is one of the most numerous and characteris-
tic groups of North American land snails. It ranges over the whole
of the Eastern United States, from Canada to Florida, and from
Manitoba to Yucatan, with species in Idaho and on the Pacific slope.
A few stragglers have reached Cuba, the Bahamas and Bermuda.
Many of the species exhibit a great amount of variation, and in
some cases the variations of several allied species form chains of
mutations almost or quite connecting very unlike species. This is
the case in the group of Polygyra appressa. Typical P. appressais
a snail having the aperture three-toothed, but the upper lip tooth is
often small or wanting. It varies toward P. obstricta var. carolin-
ensis, which is close to P. obstricta, and less so to P. palliata. In
another direction P. appressa is allied to P. sargentiana. In fact,
appressa is not far from the ancestral form from which all the spe-
140 THE NAUTILUS.

presses roughly the relationships of the species and varieties:

Polygyra appressa Say.
Surface striate, but having no spiral incised microscopic lines;
outer lip frequently having an upper tooth, or the indication of it ;
parietal tooth generally long, curving downward and nearly joining
the columellar lip.
This species was collected by Say on Long’s Expedition. It is
abundant in Illinois, Arkansas, Missouri, etc. Say’s types are lost,
but his description unmistakably indicates this form.
Polygyra appressa perigrapta Pils.
Surface striate and having crowded microscopic spiral incised
lines, especially beneath ; outer lip with no upper tooth; parietal
tooth short, not connecting with columella.
Distribution mainly southern ; Woodville, Ala. ; Cherokee Co., N.
C.; Columbus, Ga.; etc. The types are Woodville specimens.
Polygyra fallax Say.
This is, as the writer has elsewhere shown, the H. introferens of
Bland. It is not the fallax of all modern writers and collectors.
Polygyra faliax obsoleta Pils.
General features as in the type, but all teeth of the aperture much
reduced in size, the upper lip tooth nearly or wholly obsolete. New-
bern, N. C.

REMARKS ON ASTYRIS GOULDIANA.
BY A. H. GARDNER, FORT HAMILTON, N. Y.
In a careful examination of the Columbellide dredged by me
last summer in Long Island Sound, I find amongst specimens of
Astyris lunata, taken from a muddy bottom with eel grass, in 2 to
3 fathoms of water in Lloyd’s Harbor, 3 shells which are typical
examples of Astyris gouldiana Agassiz in litt. (fide Stimpson) and
again recorded from this same locality by Mr. Sanderson Smith in
“The Mollusca of Long Island and its dependencies,” Smith &
Prime. The species seems to have been considered as of doubtful
validity by Prof. Verrill, as in “The Invertebrate of Vineyard
Sound,” he includes it in the synonomy of Astyris lunata, referring
to it as a color variety identical with the Wheatleyi of Dekay, but
I think the characteristics of the shell entitle it to rank as a good
species.
The shells measure in length 4 to 44 mill., and have 8 whorls.
A. lunata rarely exceeds 3 mill. and has from 6 to 62 whorls; in
Astyris gouldiana these whorls are more convex and inflated.
The apical termination of the shell resembles that of Belemnitella
americana, whilst in the general outline of its whorls it is very much
like the well known land mollusk, Ferussacia subcylindrica. The
rostrum is not only much produced but is curved to such an extent
in two of the specimens as to give the aperture a decidedly auriform
appearance. The thick loosely appressed callus on the pillar lip of
A. lunata is represented in this shell only by a very fine glaze.
The specimens all exhibit clear zigzag markings of a brownish red,
which are more pronounced than those found on any examples of
A, lunata in my collection.
The division line between the two species seems to me to be quite
sharp, both as regards size and form. I have seen no shells which
149 THE NAUTILUS.
might be classed as intermediate, which would seem to confirm my
conclusions.
NOTE ON PATELLA KERMADECENSIS, PILSBRY.!
BY GEO. W. TAYLOR.
More than a year ago a little parcel of limpets from Kermadec
Islands was sent to me by a correspondent in New Zealand. They
were sent by way of England and were there delayed so that they
did not reach me until about a month ago.
I at once perceived that they belonged to an unknown species and
I promptly sat down and wrote a note, with a diagnosis of the spe-
cies for the Nauti.us, but on a second thought decided not to be
too hasty, and so instead of sending my note, I sent a specimen (a
young one) of the shell itself to the Associate Editor asking him
kindly to compare it with the series in the Philadelphia Museum
and let me have his opinion.
I did this because I thought and still think it possible that the
young shell may have been already described.
This morning I received the February Nauriius, and I find that
some one else has a correspondent in Kermadec Island and that Mr.
Pisbry has been beforehand with me and named the new shell most
appropriately, Patella kermadecensis.
However, as Dr. Pilsbry has only 2 specimens and I have 14, I
venture to write a line or two to supplement his description.
I may say that in my opinion, the shell is very nearly related to
pica Reeve which by the way is a South Pacific species according to
the original descriptions, although Mr. Pilsbry in his “ Manual” has
transferred it to the Mauritius.
My suite of kermadecensis consists of 2 full grown shells and a
series of 12 others ranging from 75 mm. down to 6 mm. in length.
The large ones are respectively 130 mm. x 109 mm. x 41 mm. and
1 This remarkable limpet seems to have been received by Mr. Taylor and
Dr. W. H. Dall at about the same time. Dr. Dall sent to the NAUTILUS a des-
cription of the species under the name P. Aermadecensis, but after the Editors’
description was already in print, Dall’s description of the young and adult shells,
with figures, will shortly be published in the Proc. Acad. N. S. Phila.—EDb.

130x109x354 mm., being both considerably flatter than the speci-
mens described by Mr. Pilsbry.
All my specimens are distinctly narrowed in front, and in this
particular the species differs essentially from P. patriarcha, which is
very round in outline. I have aspecimen of patriarcha exactly the
same width as the two shells above mentioned, namely, 109 mm.,
but its dength is only 119 mm. Our species is further distinguished
by its sculpture from both patriarcha and mexicana—the ribs being
narrower and much more numerous than in patriarcha and decidedly
heavier than in mexicana. Every 5th or 6th rib in the adult shell
seems to be more prominent.
Although my shells are not badly eroded there is but little color
observable outside, except in spots where smaller limpets have had
their stations. In such places the peculiar burnt red color so char-
acteristic of P. argenvillei is seen, and the same color, with an occa-
sional spot of black, edges the interior of the shell and in a paler
and browner shade blotches the spatula, which in the young shells
is sometimes entirely brown. It would seem that the color of the
interior becomes lighter with age, as is the case in many other spe-
cles.
The muscle scar is, as Mr. Pilsbry remarks, strongly marked and
callous in the adult shell, but in the young, itis not at all noticeable.
This is the case also with the 2 species with which kermadecensis is
compared.
On the whole thisis the very finest of the many fine species of lim-
pets that Mr. Pilsbry has made known to science during the last few
-years. It has no rival in size save P. mexicana, except it be the at
present unrecognized P. gigantea of Lesson from the Society Islands,
which may be found to be nearly allied or perhaps identical with
the present shell.
NOTICES OF NEW JAPANESE MOLLUSKS, I.
BY H. A. PeeeBeY-
The species described below were collected by Mr. Frederick
Stearns of Detroit, Michigan, during his second visit to Japan, in
1892. They will be illustrated in his Catalogue of Japanese shells,
now in preparation.
144 THE NAUTILUS.
Sepia Hercules n. sp.
Shell having the general form of that of S. esculenta Hoyle but
more convex ventrally; chitinous margin narrow; dorsal surface
tuberculate-rugose as in esculenta, but more coarsely so, the posterior
part having the tubercles very deeply separated, flat-topped, and
leaning posteriorly ; dorsal surface evenly rounded, with no trace of
a median longitudinal rib. Ventral surface as in esculenta, but the
striation is much closer although the shell is triple the size. Last loc-
ulus has an index of 22. Inner cone well developed, its limbs aris-
ing about one-third the length of the shell from the posterior end,
gradually rising along the sides, posteriorly reflexed and appressed
on the outer cone, leaving below a narrow small cavity. The ante-
rior edge of the inner cone does not form a shelf across the posterior
end of the outer cone as is the case in esculenta, and the cavity is
much smaller, shallower and narrower than in a specimen of esculenta
155 mill. in length. Spine very stout, conical, its root excavated
ventrally.
Length 425 mill.; greatest breadth 160 mill.; length of spine 19
mill.
This species is the giant of the genus, tbeshell being about 16Zinches
long. It is allied to S. esculenta Hoyle, but differs as above indicated.
The dorsal slope does not descend abruptly to the spine as in that spe-
cies. Of S. esculenta a good many specimens are before me collected
by Mr. Stearns. They agree well with the “ Challenger” specimens.
The size of esculenta is moderately constant, those seen by Hoyle,
Appelloff and myself being from 155 to 163 mill. long (about 64
inches). In color, S. Hercules is white in the middle, faint pink’
at the sides; whitish beneath.
A second specimen from the Loo Choo Is. exhibits the same char-
acters throughout.
NOTES AND NEWS.
The Rev. Geo. W. Taylor reports the appearance of Paludina
Japonica Mart. in the Chinese Market at Victoria, B. C. These
Mollusks are accounted dainties by the Chinese and are retailed to
them at 25 cents a pound. The occurrence of this species in the San
Francisco markets was noted by Mr. W. M. Wood in the Nauri.vs,

LIST OF SHELLS COLLECTED IN JAMAICA.
BY J. B. HENDERSON, JR.
First paper: Glandinide, Zonitide, Helicide.
The following is a list of a collection made by Mr. Charles T.
Simpson and myself in Jamaica, during the months of December
and January (in part) last. We were upon the island about one
month and although we devoted ourselves assiduously to hunting
snails, yet so much time was sent in getting about from place to
place, and otherwise lost, that our collecting appears, after all, to
have been very superficial—a mere hasty gathering of what pre-
sented itself along the roadside.
I have attempted, as far as possible, to be “up to date” in the
nomenclature.. Mr. Simpson cheerfully assumed the heavy task of —
identifying the material, for which Iam very much indebted to him.
To Mr. Vendrves I wish to extend my thanks for courtesies shown
us by him in Kingston.

others unite this with H. subconica C. B. A. There isa shell of the
above.and specimens of Adam’s species in the Nat]. Museum which
were labelled and sent by Adams to Dr. Lea. HZ. conica is a thin
shell, much more depressed and with straighter spire than this spe-
cies ; the last whorl is scarcely descending anteriorly, while in this
species it is abrupt and strongly deflected. In H. gossei the outer
lip is thickened and reflected, the columella is quite strong and
broad. Ifit were found in Cuba it would be called a Coryda, and
is suggestive of an elevated Helix alauda).
(To be concluded in June number.)
ON SOME SPECIES OF MULINIA FROM THE PACIFIC COAST.
BY W. He DALL:
Mulinia modesta, n. s. (Plate I, lower fig.).
Shell rather small, ovate-triangular, thick, equilateral, covered
with a lineated straw colored thin epidermis, ivory white with a few
rusty flecks toward the umbones; surface smooth except for incre-
mental lines; anterior dorsal area obscure, posterior larger, bor-
dered by a hardly angulated ridge on which the epidermis forms a
raised line, but without any marginal flexure behind the basal ter-
mination of this ridge; anterior end evenly rounded, beaks promi-
nent, pointed rather distant, pallial sinus well marked. Lon. 42.0
alt. 31.0, diam. 24.0 mm.
Habitat, Guaymas, Sloat, in U.S. Nat. Mus.
6 THE NAUTILUS.
This differs in its proportions from M. carinulata Desh. to which
Carpenter referred it. The latter is with little doubt merely a
young specimen of M. pallida Sby. the M. donaciformis of Gray,
better known as angulata Gray. Itis a thinner shell with a sharp
keel terminating in a somewhat recurved acute point, and having
the beaks more anterior than M. modesta. The beaks are decidedly
more distant in the latter.
Mulinia coloradoensis, n. s. (Plate I, upper fig.).
Shell larger, solid, rude, equilateral, resembling M. modesta, but
having the posterior dorsal margin more arched, the base behind
the posterior dorsal angle, somewhat concavely flexuous, and the
surface anteriorly and on the dorsal area marked with obsolete,
little elevated radii. Lon. of a medium sized specimen 49, alt. 36.5,
diam. 32 mm.
Habitat, Head of the Gulf of California in the estuary of the Col-
orado River, abundant; Dr. E. Palmer.
M. coloradoensis var. acuta, n. s. (Plate I, left fig.),
Shell thinner, longer, and more flexuous posteriorly. Lon. 40,
alt. 29 mm.
Habitat, with the typical form, common.
Mulinia Bradleyi, n. s. (Plate I, right fig.).
Shell resembling a miniature M. donaciformis but more com-
pressed, shorter, tbe beaks smaller and less prominent, the posterior
dorsal margin much more arched, no basal flexuosity, the pallial
sinus longer and more rounded internally, and the epidermis ele-
vated into narrow fringes, more or less regularly spaced. Lon. 32,
alt. 26, diam. 15 mm.
Habitat, Panama; Bradley, in U.S. Nat. Museum.
TRIODOPSIS -- MESODON.—DISTRIBUTION, ETC.
BY ROBERT E. C. STEARNS.
In the last number of the Manual (Pulmonata Series), Mr. Pils-
bry very properly unites Triodopsis and Mesodon ; both of these are
Rafinesque’s names; in order of date, the former has priority, there-
fore Mesodon must take a back seat. As to the propriety of these
names, neither is satisfactory. Triodopsis the name that must stand
for the reason above given, priority, conveys a false idea, for as.
Mr. Pilsbry says, in the remarks’ that precede his list:
'Manual of Conchology, pt. 34, pp. 74-76.
»
q
.
THE NAUTILUS. 7
“The species enumerated below have been divided by authors
into two sections, 7’riodupsis and Mesodon, but such division seems
to be artificial. Some species of Triodopsis are known to have
varieties lacking lip teeth, and these would technically fall into
Mesodon.
“In other cases, such as the group of Idaho and Washington spe-
cies, all the transitions from tridentate to toothless apertures occur.
The group of P. appressa is also a transition group. Tryon has.
resuscitated the section names Yolotrema and Ulostoma. ‘The first
of these isa Rafinesquian name totally unidentifiable; the second
was proposed by Albers for species of Polygyra ss. and Triodopsis ss.,
and did not include either of the forms Tryon uses the name for!
Aplodon Raf. has also been used in this connection ; it is positively
unidentifiable.” Whoever has had occasion to review the points
referred to by Mr. Pilsbry, cannot fail to indorse his conclusions.
Triodopsis as a name is as unsatisfactory as Mesodon ; but there it.
is, and it will have to stick. Xolotrema and Ulostoma must be con-
signed to the waste basket ; fortunately they are book names rather
than names in practical use.
Touching the matter of distribution in connection with the fore-
going, the farthest outpost of Triodopsis+ Mesodon in the Southwest
is that occupied by T. levettei at Fort Huachuca and Tucson, Ari-
zona, about on the line 32° N. latitude and 111° longitude W.
While Santa Fé, New Mexico, where the type described by Bland
was collected, is considerably further to the north and east. At the
first named place the three genera, Arionta, Patula and Triodopsis
occur in close geographical proximity, but there are wide gaps
between these localities and the west coast, and between the same
localities and the nearest eastern localities of Triodopsis+ Mesodon.
So the more northerly line of distribution of Triodopsis+ Mesodon is
interrupted or discontinuous as I have pointed out elsewhere,’ along
the line as we proceed eastward from the Pacific Coast through the
states adjoining the southerly boundary line of the Dominion of
Canada, i. e. Washington, northern Idaho and Montana (according
to Binney); then comes the gap between western Montana and the
eastward.
Within the States above named we find Triodopsis+-Mesodon,
Patula and Arionta in geographical proximity as in the southerly
region previously named. We find the Triodopsis+ Mesodon
2Proc. U. S. Nat. Mus., Vol. X VI, pp. 749—50.

characters shading into each other in both regions though perhaps
less frequently in the Atlantic Appalachian region, so that they
appear to be in no way related to geographical or environmental
differences or influences. Size, elevation or depression, color,
sculpture, etc., are exhibited as might be supposed, in many and
various facies, but the denticulation of the marginal lip of the
aperture, or the presence of a tubercular callus or tooth on the
parietal wall, or a tuberculoid lump or thickening at the base of the
pillar, all of these last characters are inconstant and variable and
are often present or absent in examples that are found in the same
colony, at many if not all places, within the territory inhabited by
the species of Triodopsis+ Mesodon group.
In Triodopsis levettei from Arizona and New Mexico, as well as
in T.devia+Mullani from the northerly region before indicated,
“we find all the transitions from tridentate to toothless apertures
occur.” A comparison between 40 and 50 examples from Coeur
d’Alene, Idaho, in addition to those previously contained in the
National collection, indicate that Mullani is but a variety of devia
as Mr. Binney has placed it*; and to quote Mr. Binney’s remarks:
“The variations of this species show very markedly the unsatisfac-
tory character of our so-called genera. Here we have the typical
devia as a Mesodon, though the variety is a true Triodopsis.”
DESCRIPTIVE NOTICES OF NEW CHITONS—IV.
BY H. A. PILSBRY.
Plaxiphora Suteri, n. sp.
Shell resembling P. biramosa Q. and P. superba Cpr.; but girdle
all over sparcely hairy, without the least indication of pores or sutural
bristles. Valves smooth, with slight growth-wrinkles, the diagonal
rib but slightly indicated. Ridge with a chestnut band with a stripe
of green on each side of it, the pleura and lateral areas uniform
blackish olive. Girdle blackish with chestnut hairs. Interior blue,
fading to white on the sutural-plates. Length about 45, breadth
about 25 mm.; (specimens all curled and contracted).
Timaru, Sumner and Port Lyttelton, 8. Island, N. Z.; (H. Suter).
A young specimen has the earlier formed portion of each valve
light brown, spotted with white. This is probably the normal color-
ing of the young shells.
‘Manual Am. Land Shells, p. 119.
THE NAUTILUS. 9
Ischnochiton elizabethensis, n. sp.
Shell small, elliptical-oblong, elevated at an angle of about 105° ;
earinated, the side-slopes somewhat convex. Color whitish or buff-
ish-olive, finely and closely mottled all over with light olive-green,
or having angular patches of olive at the sides of each valve; some-
times with black-green triangles on the ridge of some valves (valves
il, iv, vii, viii); the posterior margins of valves more or less tessel-
lated light and dark. Girdle indistinctly tessellated with numerous
small green bars or patches.
Intermediate valves not beaked. Valves finely granulated
throughout, the sculpture closely resembling that of Trachydermon
cinereus L. Lateral areas slightly raised. Posterior valve having
the central mucro somewhat prominent, posterior slope concave.
Interior bluish, with a pair of darker green rays in each inter-
mediate valve; the inflected posterior margin tessellated. Sutural
plates small, separated by a very wide, straight, smooth sinus. An-
terior valve having 10, intermediate valves 1-1, posterior valve 11
slits; teeth smooth and sharp; slit-rays showing as whitish lines;
posterior tooth in intermediate valves short, removed from the pos-
terior margin of valve by about its own length. Eaves narrow.
Girdle densely clothed with smooth, flattened imbricating scales.
Length 102, breadth 7 mm.
Habitat: Port Elizabeth, S. Africa.
This little species closely resembles T’rachydermon cinereus L.
(marginatus auct.), or dentiens Gld., in sculpture and coloration,
but differs from them in the totally diverse girdle-covering. I am
indebted to Mr. G. B. Sowerby for specimens. It is the Ch. mar-
ginatus of his useful “ Marine Shells of S. Africa,” p. 50.

Siphonaria sirius n. sp.
Shell oblong, polygonal, low-conical with subcentral, erect, apex ;
primary ribs all single, generally 7, strongly elevated and white ; inter-
spaces wide, dark brown, radially finely ribbed. Interior brown-
black, the larger ribs indicated by white rays; Siphon occupying a

chestnut colored), the region of the muscle-impression bordered with
chestnut stains. Length 22, breadth 17-19, alt. 5 mm.
Sagami, and Kashiurazaki, Boshiu, Japan (Frederick Stearns !)
This species differs from S. atra Q. & G., coreensis A. & R., and
their allies in having the siphonal rib single and simple. It is
probably the species identified as S. atra by Dunker and other
writers on Japanese shells. Several hundred specimens collected
by Mr. Stearns agree in the characters above given. Not one shows
any tendency to double the siphonal rib.
Helix (Euhadra) yaeyamensis n. sp.
Shell sinistral, perspectively umbilicated, depressed, thin but
rather solid, light brown with a supra-peripheral brown line. Surface
irregularly wrinkle-striate and in places showing an excessively fine,
superficial spiral striation. Spire low conoidal, composed of 6 con-
vex, slowly widening whorls, the last nearly twice as wide as the
preceding, a trifle descending in front, rounded at the periphery and
beneath. Aperture oblique, wide lunate; peristome flesh-tinted, nar-
rowly expanded and subreflexed, and slightly thickened within,
dilated at the columellar insertion. Alt. 17, greater diam. 272+ —
lesser 28 mm.
Yaeyama (Okinawa) Island, Loo Choo group. (Frederick
Stearns).
This species is apparently most nearly allied to the Chinese H.
latilabris Mlldff., but the umbilicus is more open, the lip narrower,
aperture more oblique, etc. The umbilicus is wider and more open
than in H. quesita. |
ISAAC LEA CHAPTER, AGASSIZ ASSOCIATION.
BY DR. M. L. LEACH, WEXFORD, MICH.
A vigorous chapter of the Agassiz Association has been in exist-
ence for several years and is known asthe “ Isaac Lea Conchological
Chapter.” Its members are scattered over this country from Maine
to California, and some of them reside in Canada. The Chapter is
divided into sections, each having a secretary, who has special
knowledge of his department. A juvenile section has recently been
added, and a goodly number of boys and girls are learning about
shells. As the members are so widely separated, most of the com-
:
THE NAUTILUS. iW
munications must be in writing. The most valuable papers consist
of annual reports, which are sent to the members in turn, and are
finally preserved by the general secretary. During the past years
excellent work has been done by members of this Chapter, and an

MELONGENA CORONA Gmel.
BY FRANK A.*WHITE, GEORGIANA, FLORIDA.
For many years I have seen these shells and have been sure that
they were from a living mollusk, but until March 20, 1894 had
never seen one alive.
On that day I went from Georgiana to Oceanus and as the river
was very boisterous I went by way ofthe Thousand Islands. When
about half a mile from my destination we all went ashore for a few
minutes and there in the shoal, still water, were several pairs of
Melongena corona apparently in the act of copulation. I very much
desire to visit the station again when I have more time at my com-
maud and secure more of the shells and observe more closely their
actions.
Structural and Systematic Conchology in the description says
“operculum solid” but does not give material. It is horny and not
very thick.
There is some variation in the living shells some having varices
near anterior end of aperture, others smooth. Some time ago I
found a broken shell much larger than any recent shell I have seen.
The spire and part of the body whorl were gone but the aperture
was intact and measured 3 inches in length including the callus of
posterior canal. This seems to indicate that in “ prehistoric times”
these mollusks attained a much greater size than at the present
time.
I neglected to say in the proper place that the living shells were
in the Banana river in brackish water.

NOTES AND NEWS.
Mr. Epwarp W. Roper has returned from a two months trip to
Jamaica. He reports a good time and considerable collecting.
PURPURA SAXICOLA VAL.—A large suite of this species recently
presented to the collection of the American Association of Con-
chologists by Mr. Witirarp M. Woop, shows an extraordinary
amount of variation. Some very large examples are represented,
the largest measuring 384 mm. alt. Others show variations from
smooth to strongly corded. In color they vary from livid-white or
gray; white to bright orange and to black, some being spirally
banded with brown in the intervals between the white spiral riblets.
The entire lot was collected in San Francisco County, Cal.

OBITUARY.
Mrs. D. L. GaRLIcK expired suddenly March 16, 1894, in San
Francisco. She was spending the winter in Alameda, as the
guest of her sister, Mrs. Gaylord, 2116 Central Avenue, and the two
ladies went out to the Cliff House and vicinity yesterday to spend
the day collecting shells.
They climbed a precipitous height near Land’s End station on
the line of the Ferries and Cliff House Railroad, and when she
reached a little station on the road, they sat down for a rest. Sud-
denly Mrs. Garlick fell forward and dropped on the floor. _ Upon
trying to raise her up, Mrs. Gaylord was horrified to see that her sis-
ter was dead.
- Weakness of the heart, aggravated by over exertion, is attributed
as the cause of death.
The home of the deceased was at St. Paul, Minn., and she made
it a practice for many years to spend the winters in California,
either in Alameda or San Diego. She had been interested in the
collection of shells for some years.

UROSALPINX CINEREUS IN SAN FRANCISCO BAY.
e
ROBT. E. C. STEARNS.
The Report of the U. S. Commissioner of Fish and Fisheries
1889-91 just published (March, 1893), contains an interesting and
valuable paper by Mr. Charles H. Townsend of the A/batross on
“The Oyster Resources and Oyster Fishery of the Pacific Coast,”
etc., etc., in which he mentions the occurrence of Urosalpina cine-
reus (—Fusus cinereus Say) on the beds of transplanted Eastern
oysters near Belmont. It appears that this species, the “drill” of
the oystermen, “has not become troublesome until very recently, and
even now is abundant only in the southern part of the Bay.
“ Atthe Belmont beds I had no difficulty in gathering a quart
of these mollusks, in Jess than ten minutes, by merely turning over
the large oysters when the water had receded from the beds.
* * x x x x x x *
“ This destructive animal may have been introduced much earlier
than the oyster-men suppose, as a few individuals accidentally
imported among the original oysters would require several vears to
increase to the present numbers.” They had not at the time of Mr.
Townsend’s investigation, been detected on the oyster beds at Mill-
brae, which are much nearer the sea.
This is the second form that has incidentally been introduced
with the oysters from the Atlantic seaboard, Mya arenaria being the
first ; the latter has already become abundant, and therefore a val-
14 THE NAUTILUS.
uable addition to the food supply of the West Coast. It seems
strange that some of the conchologists or collectors should not have
detected the Urosalpina before; for while, no doubt it multiplies
rapidly under favorable conditions, still the abundance of this form
as shown by Mr. Townsend’s investigation, indicates that it must
have been on the Belmont beds for several years. The common
Purpura of the coast, P. crispata has heretofore been found in con-
siderable numbers on some of the oyster beds in San Francisco Bay.
How it compares with the dri//, as an oyster borer and pest to the
oyster men, I have not learned.
We may reasonably look forward to the finding of a third eastern
species, as an accidental or incidental transplantation ; it may be
already established there, in some of the beds of eastern oysters.
I refer to the ribbed Mytilus, M. hamatus Say, which is so frequently
met with here, attached to Ostrea virginica. Mr. Townsend or
some of the local naturalists, should look after it—if not there now,
it will be sooner or later.

A FEW NOTES ON HELIX APPRESSA.
BY A. |G. WHEFEEELY.
In the April Nauritus, Mr. Pilsbry has given us his description
of Triodopsis appressa, and named a variety thereof, perigrapta. As I
am at war in a good humored way, with the modern habit of desig-
nating the hundreds of varieties of our land shells by latin names,
I hope to make my reasons plain in the following brief note. Re-
ferring to, but not copying Pilsbry’s description of perigrapta, I will
say that I have shellsin my collection exhibiting every gradation of
the sculpture in question, from a few “spiral incised lines ” in speci-
mens from Cherokee Co., N. C., to those in which these lines are not
only crowded, but much more pronounced individually; and as
these specimens are heavily ribbed, they aid in giving some parts of
the surface of the shell a beaded appearance.
Every gradation may be traced in the specimens which I have,
from the smooth albino form found at Cincinnati, Ohio, to those
rough mountaineers from Morrowville, Tenn. Where then, does
THE NAUTILUS. 15
perigrapta begin and where does it stop? Any of these varieties is
just as much entitled to name as is the one selected for this honor.
Among the rest is a large var., 23 mm., from Lookout Mt., Tenn.
This variety is almost smooth or very sparingly costate. It is
slightly wrinkled like Z. inornatus. Butit is crowded with these
incised lines above and below !
Another form that I collected at Gasper, Picking Co., Ga., in
August, ’83, is very costate, and has the incised lines very much
crowded and developed. The Lookout shells have the parietal
tooth long, curving, and joining the columellar callus in the umbili-
cal region. The Gasper specimens have this tooth short and very
erect. They also have the lip very much widened, and the spire ele-
vated. I have, in my suite of this species, four shells, taken at ran-
dom from a lot collected at Murphy, Cherokee Co., N. C., in every
one of which the upper tooth is well indicated, the parietal tooth is
short and erect, the spire elevated, the body whorl obtusely carinate
and the whole surface above and below is crowded with “ microscopic
spiral incised lines.” Now which is perigrapta? The deep cost
and the multitude of spiral incised lines roughen the epidermis of
the Morrowville examples and begin to introduce the conditions
attaining in subpalliata. These shells, in consequence, have a some-
what dull appearance, while the Lookout Mt. and Cherokee Co. spec-
imens are highly polished.
A variety from Braden Mt., ‘Tenn., is heavily costate, and has the
spiral lines (as has every shell of appressa) but not “ incised.”
These shells range from 12 mm. to 25 mm. (my largest specimen of
sargentiana). This last form is costate, has the erect tooth, the cari-
nate body whorl, and the spiral lines, not “ incised,” and is in fact
nearer to the typical appressa, in every aspect, than the highly
polished and shiuing specimens from N. C.
Now what is the philosophic method in treating such a problem ?
Is it to give all these varieties names, loading up our literature and
check lists with trinominal designation for varieties that differ in the
same County of the same State? Or shall we write our labels ap-
pressa var. with locus and so on tothe end? There is at least one
collection in the U. S. where the latter method prevails and will to
the end. I am tempted, in this place, to prune and reset Mr. Pils-
bry’s phylogenic tree according to my ideas, but I will not take
space for so doing now. I do not, however, believe that dentifera is
the root or that the branches sargentiana, appressa and perigrapta
16 THE NAUTILUS.
are of equal specific rank, or that two of them are of any specific
rank whatever; and I base my statement not only upon the varie-
ties of this species here briefly mentioned, but upon many others in
my collection, from many States and mostly collected by myself.’
Why do we not take to our heart of hearts the great truth that
there are no hard and fast lines in Nature’s record either present or
past, and hold close the splendid proof given by this shell ?
The foreign student who has not seen all our shelJs can tell noth-
ing by these names, but if he knows appressa he will have the
truth suggested by eppressa, etc. So, too, our catalogues will be
something besides names and nobis! They will be expressive of
facts in the life history of this humble race.
This is the method that appeals to me as the scientific, the truth-
ful, the suggestive method ; and I shall never cease to believe in it
and to work for it.
NOTICES OF NEW JAPANESE MOLLUSKS, III.
BY H: A. PRESBRY.
Siphonaria acmeoides n. sp.
Shell oblong, nearly equilateral, but with excentric apex like S.
radiata A. & R. (Zool. Samarang pl. 13, fig. 2). The even surface
hardly modified by the 9-16 low, wide ribs, between which it is very
finely radially striated. Siphonal rib wide but low and inconspicu-
ous. Apex spiral, bent down and appressed. Interior blackish or
chestnut within the muscle impression, outside of which it is radially
striped black and white, the siphonal channel extremely shallow
and inconspicuous. Color outside whitish-buff, speckled and mac-
ulated with brown, or whitish on the principal ribs, the intervals
black-brown. Length 12}, breadth 93, alt. 33 mm.
Prov. Boshiu, Japan (Frederick Stearns).
This little species very closely resembles Acmewa Heroldi in the
general form and the coloration of the interior.

PEROSTYLUS, A NEW GENUS OF FUSOID GASTROPOD.
BY H. A. -PEBSBRY.
In volume IX of the Manual of Conchology, Mr. Tryon described
and figured a shell from Port Darwin, N. Australia, as Cerithiwm
(Colina) Brazieri. Having occasion recently to study a large
number of C. macrostoma Hinds, the type of the subgenus Colina, I
was at once struck by the notable difference between this species and
C. Brazieri. The latter does not seem to belong to the Cerithiide
at all, much less to the group Colina. I am more inclined to view
it as an aberrant type of the Fuside, although only a knowledge of
the operculum and dentition can decide the question. The new
group may be thus diagnosed :
PrROSTYLUS n. g. Gen. Char.: Shell cylindrical or pillar-shaped,
thin, with decollated apex like that of a Rumina or Cylindrella;
last whorl but little wider than the spire; aperture small, shaped
like that of Fusus or Chrysodomus (Sipho), produced in an open
canal below; columella straight or sinuous, without folds; outer lip
thin and fragile. Type Cerithium (Colina) Brazieri Tryon.
The decollation of the spire is not the result of erosion, as in the
species of Potamides and Melaniide, nor is the apex filled with a
thick solid mass of shell-tissue as in those groups. In Perostylus
the structure is like that of Rumina decollata or the West Indian
Cylindrellas.
The genus will consist for the present of two species.
P. Brazieri Tryon.
Shell cylindrical, white, fragile, hardly tapering, consisting of 64
remaining whorls, each carinated and obtusely nodulous in
the middle, and obsoletely spirally lirate. Last whorl with
one or two spiral cords below the peripheral keel, and more
distinctly spirally lirate, the base nearly smooth. Aperture
one-third the length of the shell ; outer lip thin and fragile,
columellar lip distinctly sigmoid, smooth. Alt 21, diam.
6 mm.
Habitat, Port Darwin, N. Australia (John Brazier).
If this shell could be reproduced in the form it would have were
the earlier whorls not decollated, it would be by all odds the most
attenuated Gastropod known, surpassing even the Terebras in the
number of its slowly increasing whorls. The numerous young shells
18 THE NAUTILUS.
before me fully support this opinion. Unfortunately none of them
are young enough to show the apex. The youngest of them,
although not half the diameter of the adult, show the same almost
imperceptible degree of tapering.
P. Fordianus Pilsbry.
Shell cylindrical, white, thin’; spire hardly tapering, but last
whorl notably wider. Remaining whorls 42, sculptured as
in the last species, but the next-to-the-last whorl is distinctly
narrower than the preceding whorl. Aperture nearly one-
half the length of the shell; outer lip thin, simple; colu-
mella straight, a trifle deflected toward the left below. Alt.
19, diam. 74 mm.
Habitat unknown. The specimens were presented to the Acad-
emy by Mr. John Ford.
This species is distinguished from the preceding by its straight,
not sigmoid columella, and by the fewer remaining whorls. As the
last character might possibly be the result of greater age, I do not
now attach much importance to it, although it will probably prove
to be a constant specific feature.

NOTES AND NEWS.
VARIATIONS DUE TO STATION IN POLYGYRA (STENOTREMA) HIR-
suTA Say.—Having read your “Descriptive Notes on Certain
Forms of Polygyra” in the April “ Naurixus,” I take the liberty
of sending you two forms of P. hirsuta Say that I have found in this
County. The first measures 8 mm. in diameter, is very common on
low ground, in some places being the most plentiful species of Helix
found, while the second form, 6 mm. diam., I have only found on
one high, and dry hill, clear up at the top, among moss and stones,
where the Trailing Arbutus (Hpige@a repens) and Wintergreen grow.
I think you will find No. 2 alive, as I only collected them last
Sunday. Under the microscope you will see that while No.1 has
“sharp, rigid hairs” those of No. 2 are curved or hooked. It also
seems to me that there is a noticeable difference in the “ notch.”—

SYNOPSIS OF THE MACTRIDE OF NORTH AMERICA.
BY WM. H. DALL.
In revising the group of Mactracea with the intention of working
up the Tertiary species of North America it became necessary to go
over the whole of the recent species and enquire into their synony-
my. The following lists of east and west American species seem
likely to be useful to students, as the synonymy of the group has
been in a confused state hitherto. The distinctions between the
different types of Mactride have hitherto largely been lost sight of,
owing to the practice of confounding all together under one or two
generic names; and while, to those habituated to previous methods,
the present arrangement may at first sight seem excessively sub-
divided, I have found, in going over the whole group of Mactracea
in the National Collection, that features of geographical distribution
and characters of importance in the development of the family in
time, are brought out by it in a way which was wholly impossible by
earlier methods. The present subdivision3compared with that of
most other groups of mollusks at the present time is not excessive,
and by those who may be led to a close and accurate study of the
mollusks in question hereafter I believe it will be found to be useful
and convenient.

—=Mactra campechensis Gray, 1828.
Doubtful or spurious East American species.
Mactra nucleus Conr., 1831, from “New Jersey” is exotic, and
stated by Tryon in the Am. Marine Conchology to be a native
of Manila.
Mactrelia (Harvella) elegans Sowerby, has been reported from
“Florida” where it is unknown, and ‘‘ Jamaica” probably by
a misidentification. There is no specific difference between
Panama and alleged Antillean specimens and the name cannot
be admitted to the East American list without further evidence.
Spisula subtruncata Da Costa. What appears to be a somewhat de-
formed subfossil valve of this species was sent from Lawlor’s
Lake, New Brunswick, to Dr. Stimpson by Matthews, many
years ago. It isin the National Collection but no other spec-
imen seems to have been collected on this side of the Atlantic
and it is probably a ballast shell.
Spisula solidissima var. Acadica Matthews; Can. Nat. viii, no. 2, p.
111, 1877, from the higher clays beds at St. Johns, N. B. See
also Ann. Soc. Mal. de Belgique ix, 1874. This may be
founded on the specimen of S. subtruncata above mentioned,
though Mr. Matthews’ paper is not sufficiently explicit to deter-
mine. It is probably an exotic as he suggests.
Spisula “ subimbricata Mont.” Cockerell, in list of Jamaica shells,
Nautilus, vii, p. 115, 1894. Montagu described no Mactra of
this name. What the shell intended may be, is of course im-
possible to say, but possibly the following :
Mactra Richmondi n.s. Shell thin, small, white, inequilateral, with
the posterior end shorter and its dorsal aspect obtusely keeled ;
surface nearly smooth, except the dorsal areas, which have short
deep concentric grooves; beaks moderate, adjacent; lateral
teeth rather short and small, smooth; pallial sinus small,
rounded, extending forward to the vertical of the beaks ; poste-
rior end obtusely pointed. Longitude 21; alt. 14; semi-
diameter 4.5 mm.
One valve on the beach at Greytown, Nicaragua; Chas. Rich-
mond. It isthe only American species belonging to typical
Mactra with grooved dorsal areas.
Mactra Cumingiana “ Bush,” Zool. Rec., 1885, from Cape Hatteras,
is a lapsus of the Recorder for Mactra Cumingiana.

HELIX (ARIONTA) COLORADOENSIS :—A NEW LOCALITY,
ROBT. E. C. STEARNS.
This form first detected by Dr. C. H. Merriam' in the Grand
Caiion of the Colorado, opposite the Kabab plateau, at an elevation
of 3500 feet, in 1890, and subsequently near Resting Springs’ in the
southeastern part of Inyo County, California, at an elevation of 900
feet above the Springs, in February, 1891 by Mr. Vernon Bailey
has recently (March of the present year) been obtained by Mr. C.
R. Orcutt of San Diego, at Mountain Springs, Colorado desert, San
Diego County. Mr. Bailey found his specimens among rocks on a dry
hill: Orcutt found but one example a bleached shell with the band
barely discernable. With these three points in mind it will be
seen, that a wide range of distribution is already indicated for this
species. .
NOTICES OF NEW JAPANESE MOLLUSKS, IV.
BY H. A. PEESERY.
Macroschisma Lischkei n. sp.
Nemoto, Boshiu (Stearns).
Shell oblong, the length less than twice the breadth; lateral mar-
gins convex, anterior margin well rounded, posterior margin bluntly
rounded, subtruncate. Anterior slope straight, decidedly less than
half the length of the shell; side slopes straight.
Surface sculptured with fine radial striz, alternately Jarger and
smaller, finer on the forward half of the side slopes ; slightly decus-
sated by growth lines. Color either (1) uniform black, or (2)
closely speckled with black on a buff ground, or (3) crimson
with or without dusky rays. Posterior slope long for the genus,
about one-fifth the length of the entire shell; flattened or subcon-
eave behind the hole, but not guttered. Perforation large, oblong,
slightly narrower in front, and wider behind, with a very narrow

eroded tract behind it. Length of hole contained two and one-half,
times in length of shell. Interior bluish-white, the hole callus darker
at the sides. When resting upona plane surface, the peristome of
the shell is seen to be very much elevated behind, and but little less
so in front ; the latero-basal margins strongly curved throughout.
Length 173, breadth 9, alt. 5 mm.
Length 16, breadth 94, alt. 5 mm.
Twenty-two specimens collected. This seems a very distinct spe-
cies; the position and proportions of hole, the long posterior and
short anterior slope, and the strongly curved basal margins being
especially characteristic, and unlike other described forms.
Cyrena luchuana n. sp.
Shell large, inequilateral, oblong, the anterior end short, broadly
rounded, posterior end long, produced, and squarely truncated;
basal margin gently arcuate, dorsal margin narrowly rounded at
the beaks, the anterior slope short and nearly straight, posterior
slope long, rectilinear. Valves strong, convex, the posterior dorsal
area flat or concave, bounded by a blunt angle, another obtuse
angle extending from beaks to lower posterior extremity. Interior
white, stained with buff-olive on the hinge. Cardinal teeth bifid ;
anterior lateral very short and strong; posterior lateral long, remote
from cardinals. Cuticle dull brown, with a yellow under color,
irregularly wrinkle-striate, lamellose behind, and less so over the
whole disk. Length 94, breadth 72, diam. 47 mm.
Yaeyama Island, Loo Choo group (Fr. Stearns).
Cyrena (papua var.?) yaeyamensis,
Shell shorter than the preceding, being less produced posteriorly,
the posterior surface not so distinctly angular, posterior truncation
less marked; anterior lateral tooth not so short. Anterior dorsal
slope of hinge line straight, posterior dorsai slope slightly convex.
Color and sculpture asin /uchwana, except that there is usually
some oblique corrugation of the posterior slope. Length 75,
breadth 63, diam. 36 mm.
Yuaeyama I., Loo Choo group (Frederick Stearns).
This may prove to be a form of Cyrena papua, or of CO. buschit
Phil. of China, but it is more triangular, with the posterior margin
more produced.
Cyrena fissidens n. sp.
_ Shell resembling C. sinwosa as figured by Clessin (Conch. Cab.,
pl. 45, f. 1), but the posterior lateral tooth and corresponding pit

much slenderer and somewhat longer, the posterior cardinal tooth
in right valve split by a sulcus much broader than the space be-
tween the posterior and the next adjacent cardinal! tooth. Valves
orbicular, very convex, lightly wrinkle-striate, and covered with a
black cuticle. Posterior slope depressed, with a radiating wide and
shallow furrow, rendering the margin slightly emarginate. Dorsal,
anterior and basal margins well rounded ; posterior margin obliquely
* subtruncate. Length 86, breadth 77, diam. 49 mm.
Yaeyama I., Loo Choo group. A single specimen (Frederick
Stearns).
Siphonalia Stearnsii n. sp.
Shell fusiform, solid, brownish; spire conical, shorter than the
aperture, consisting of 8 convex whorls, which are finely spirally
? _ lirate, and closely and strongly plicate; plicee becoming partly or
wholly obsolete on the body-whorl, which is very indistinctly or not
at all shouldered, and runs upward somewhat toward the aperture,
causing a narrow, small posterior channel. Aperture shaped as in
S. fuscolineata Pse. but wider, the inner lip smooth, its edge raised
and free; outer lip with a wide yellow internal border, inside of
which it is thick, lirate and white. Anterior canal strongly
recurved, short. Alt. 46, diam. 25mm. Obliquealt. of aperture
29 mm.
Allied to S. longirostris Dkr., but less elongated, with more
strongly plicate spire and different aperture, I cannot see that any
of A. Adams’ unfigured species agree with the specimens before me.
The spire is longer and more plicated than in S. fusoides Reeve, and
the canal more recurved.

MY DAILY WALK.
WILLIARD M. WOOD.
What student of conchology does not take a daily walk, whether
it be to one’s business house, a stroll after luncheon or a walk home.
And while thus taking the outdoor exercise, does one “ keep an eye
open ”
for specimens? If not, do you imagine how many speci-
mens are passed by?
My exercise consists of a daily walk of sixty blocks; thirty of
which, I walk to my office, starting at 8.30 o’clock in the morning,
and the balance, coming home at 5 o’clock in the afternoon.
34. THE NAUTILUS.
Every day I carry with me, a smail tin box, one which I can
very conveniently carry in my pocket, in which my “ finds” are
contained ; and when a morning is very damp, the result of a rain
the day before, or when a heavy fog settles over the city, then I
take with me a much larger box, inasmuch as I find that I can col-
lect two or three times the amount of specimens that I would when
the ground is not very moist.
Some mornings I gather great quantities of Zonites lucidus
Drap. (sent to Mr. Pilsbry to be identified) while other mornings,
Agriolimax agrestis Linn. may be found very numerous. However,
the following list may be called a fair sample of the specimens I
collect, while on my daily walk.
Specimens gathered on Nov. 11, 1893. No. collected.
Helix (Lysinoe) nickliniana Lea var. reticulata Pfr. 48
Zonites cellarius Mull. 5)
Zonites lucidus Drap. 32
Ariolimax columbianus Gld. 5
Amalia hewstoni Cooper 13
Agriolimax agrestis Linn. 27
Limax maximus Linn. 30
Prophysaon andersoni Cooper 21
Total 179
I may add, that of the above species, although Limaz maximus
Linn., has only been an inhabitant of this country for a period of
about two years, it has multiplied so greatly, that it has become a
nuisance to people who have flower gardens.
The slugs I find, generally crawl across the cement sidewalks and
walls surrounding residences, while the Zonttes apparently delight
in crawling over the wooden door steps, and the Helix reticulata
prefer secluded spots in vacant lots, among the grass or under
boards, Of the last named species, I have at present, almost a
thousand specimens and of the Zonites lucidus Drap. over three
hundred specimens.
Is it not worth while then, to be “ on the lookout” for specimens
when out walking? One can thus see how I profit by my daily
walk.

NOTES AND NEWS.
REVERSAL OF CLEAVAGE IN Puysa.—Mr. Henry E. Crampton,
Jr., has recently studied the early stages of Physa and Limnea. In
the former the cleavage is according to the typically spiral type,
but totally reversed in direction. It will be interesting to learn
whether this is directly correllated with the sinistral form of the
adult.
On the 28th of January last, A. Ta. von MrppENpDorr®F, the cele-
brated traveller and zoologist died at his home near Dorpat.
Middendorff is especially known to American conchologists as a
writer on shells of the northwest coast. -
~ Buiimus optonaus has recently been found by Mr. H. G. Hub-
bard, of the U. S. Agricultural Department, flourishing in St. Kitts,
where it has been introduced from Antigua by a resident concholo-
gist. Thisis perhaps, worth making a note of, since it has not been
found so far north, and some one hereafter may suppose it native.
Mr. Hubbard finds that a species of Tillandsia holds large quanti-
ties of water in the axils of the leaves; a good sized one he says
will hold a barrel of water, and this water in the mountainous for-
ests of Montserrat has a fauna of its own. He brought an Amphi-
bulima (possibly A. patula) and Pellicula (? depressa) which he
found in these moist retreats —W. H. DALL, in Jetter.
Pupa sYNGENEs Pils., has recently been received by the National
Museum from Beaver Creek, Montana, (a tributary of the Little
Missour!) in the river drift. This is a new locality, I believe, and
interesting on account of its distance from the criginal place (Ari-
zona).— W. H. Dat.
Nore on Liparus.— When studying the apices of the Australian
land shells Panda and Caryodes, the writer had occasion to examine
those of the Australian Bulimuli belonging to the subgenus Liparus
of Albers. In this group the earlier whorls are very closely pitted,
somewhat like a thimble, while in Panda they are decussated,
and in Caryodes spirally lirulate. The characters of the earlier
_ whorls seem to be of much greater importance than has generally
been supposed. Placostylus agrees with Liparus in the peculiar pit-
ting. Bul. (Leucotenius) favannii has a closely costulate apex, like
our B. schiedeanus. The name Liparus in mollusca is preoccupied
by Liparus Olivier, Entomologie, ou Hist. Nat. des Insectes, Vol.

SPIRULA PERONII in Jamaica.—Mr, Edw. W. Roper reports find-
ing a specimen of this cephalopod containing the animal, during
his recent visit to Jamaica.
Mr. F. C. Baker has been appointed Curator of the zoological
department of the Field Columbian Museum at Chicago.
The collection of shells of the late Dr. PHitre P. CARPENTER is

uable and authoritatively named collection. Address Mrs. Minna

Some ARKANSAS SNAILS.—On my trip here (Fort Smith, Ark.,)
I did what I did some years ago—walked from Winslow, on the top
of the Boston Mountains, to Porter, six miles this side. I collected
quite a number of shells, and will send you some living Triodopsis
edentata, Stenotrema labrosum, Polygra Sampsoni and P. Jacksoni.
I got the edentata from the top of the mountain to Rudy, a vertical
distance of 1500 feet. At the latter place they are found with the
ordinary Triodopsis inflecta. I hope you will have time to examine
the internal parts. I find that where I got the type specimens was
in Washington County, instead of Crawford; but on this trip I
gathered them in both counties —F. A. SAmpson, in letter.
THe Micuican Fisa Commission has commenced an investiga-
tion of biological conditions of the Great Lakes, with especial refer-
ence to the life history of the white fish. The work will include a
determination of the fauna and flora of Lake Michigan at Ann
Arbor, and of their vertical and horizontal distribution. This de-
termination will be both qualitative and quantitative, and will be
particularly directed towards a study of the life history of the white
fish and lake trout. Since the life of the water constitutes first or
_ Jast the food of the fish in it, this determination will afford some
idea of the value of this locality as a breeding ground for fish and
of its adaptability as a planting ground for the fry. The party at
work in the laboratory will consist of various specialists, Mr. Bryant
Walker, Detroit, Mich., taking charge of the mollusca.

Thanks to the BinneEys, father and son, we American malacolo-
gists rarely have anything but comparatively fair sailing when we
have occasion to work with the land mollusks of our own Country.
Only those who have spent daysand months striving to unravel the
tangled threads of synonymy, striving to see a little way into the

Foridensis.
mysteries of structure, of phylogeny
or origin, and of geographic distribu-
tion, can rightly appreciate the debt
we owe totwo men who have given
the best energy and scholarship of
their lives to the study of American
land shells.
These reflections come to me as I
think on the question of the number of
species of Orthalicus found in Florida—
a matter in which it seems to me that
Mr. Binney’s books have not been
clear.
The species of this genus (or per-
haps better, swhgenus, for structurally
it differs from Liguus only in trifling
points) are not, for the most part, at
38 THE NAUTILUS.
all well defined. The older authors mixed them sadly; and we
moderns are in some danger of drawing over-fine distinctions
Still, the systematic zoologist who makes any voyages at all, must
perforce sail between Scylla and Charybdis. The great art is to
steer a middle course.
Returning to our Orthalicus, we notice that the older collectors
found only the zebra-striped forms in Florida, these being identical
with the species so common in Jamaica, and known for many years
under the names zebra Miller and undatus Bruguieére.
Some authors have attempted to establish wndatus and zebra as
distinct species, but the last name was proposed for a medley of
Achatinas and Orthalicus, not including the form now known as
undatus ; so it will be dropped from the lists entirely. The well-
known Florida and West Indian species is O. unDATUs Brug., (see.
W. G. Binney’s works). It is not known from Mexico.
Besides this form, we find in a number of localities in Southwest
Florida, an Orthalicus with nearly white shell, spiral brown bands
and occasional oblique stripes, but none of the zig-zag flames so
characteristic of O. undatus. This form was described by the writer
in 1891, as follows:
Orthalicus melanocheilus Val. (1833).
One of the most distinct species of the genus, described originally
from ‘‘ New Spain” (7. ¢., the Middle American mainland). The
Florida specimens differ from the Mexican and Central American
in a number of characters and seem to me perfectly distinct as a
geographic variety.
0. melanocheilus var. Floridensis Pilsbry.
Shell white or slightly stained with brown, having no longitudi-
nal zig-zag flames. The body whorl has three narrow brown bands,
the upper one often broken into spots. There is a black varix on
the penultimate whorl, and one or two on the body whorl. The
varices are generally not visible within the aperture, but the three
spiral bands are conspicuous there. Lip bordered with blackish-
brown ; columella white edged, but parietal callus deep brown.
The types of this variety are from near Cape Sable, Florida.

O. melanocheilus var. floridensis is probably a dark-mouthed variety
of O. undatus;” but he had not seen a Florida specimen. The
fact is that this is one of the most distinct forms of the typical
group of Orthalicus, and if it be a variety of undatus, then undatus
will cover al/ of the typical group of so-called species admitted by

DouBTFUL OR SPURIOUS Wrst AMERICAN SPECIES OF MACTRIDZA.
There is no typical Mactra or Spisula known from the Pacific
Coast.
Mactra angusta Desh., 1854, from the Gulf of California as figured
by Reeve, resembles a refined M. cal‘fornica Conr. Wein-
kauff’s figure is undoubted californica Conr. not Desh. I have
not seen authentic specimens.
Mulinia bistrigata Morch, 1861, appears to be a mere color variety
of M. pallida.
Mulinia Gabbi Tryon, is stated to have come from Lower Califor-
nia, but has not since been reported from there. It is very
close to the South American M. exalbida Gray, and as M. exal-
bida is found near Panama it may reach California.
Mactrella subalata Morch, 1861, was described from a single worn
valve obtained at Realejo, Costa Rica. This was probably a
ballast shell or one in some way transported from the Atlantic
Coast. Caribbean shells are taken to Panama and other Pacific
ports for sale to visitors, as I have personally experienced.
Mactrella alata, of which subalata is a pure synonym, has not
been authenticated from the Pacific where it is replaced by M.
exoleta Gray.
M. (Macetrella) lacinata Cpr., 1856; Panama, Bridges; is probably
a Mulinia, notwithstanding its reference to Mactrella. Its
small size (07 in.) points toward immaturity. It has not been

figured or sufficiently described to enable it to be referred to its
proper place in the family.
Lutraria Sieboldii Desh., 1854; “Vancouver Id., Kellett”; is a
Japanese species, with which D. lucida Gld., 1861, (a young
shell) is probably synonymous.
Darina declivis Cpr., 1865, has not been found by any collector on
the N. W. coast since reported from a collection alleged to
have been made by Dr. Forbes, R. N., but which had passed
through the hands of a dealer. The same lot contained a
shell described by Dr. Carpenter under the name of Saxidomus
brevisiphonatus, which also has not subsequently been discover-
ed in the region.

A FEW NOTES ON HELIX TRIDENTATA.
BY A. G. WETHERBY.
I have recently received from Mr. Pilsbry his Critical List of
Mollusks collected in the Potomac Valley. Proc. Acad. Sci., Phila.,
1894, pp. 11 to 31, with plate. |
This isa valuable and interesting contribution from this inde-
fatigable worker. But he has again dropped into the business of
adding latin names to varieties of our common shells, so that we
now have from Say’s species no less than three trinominal relations,
viz., H. tridentata edentilabris ; H. tridentata juxtidens and H. tri-
dentata frandulenta. J propose, in this note, to briefly review this
case, as Mr. Pilsbry, having the spirit of the true naturalist, has
kindly opened his pages for that purpose.
This species, though exhibiting so many variations, due to differ-
ences of station, or to inherited race proclivities, has always a gen-
eral facies that marks it well. No student of our land shells need
ever or does ever, mistake it for anything else. It cannot be con-
founded with H. fallax Say, though Dr. Binney believed them to be
identical ; nor is there any other North American species, worth any-
thing as such, that need be taken for it. Now with this fact well
44 THE NAUTILUS.
before us, I wish to use this criticism of these unnecessary names to
illustrate the suggestions as to labeling such shells, made in my
notes on H. appressa in the June Nauritus. The chief forms of
Hi. tridentata in my collection are the following :
The type, from many localities in many States; I need not cite
them here.
A variety found under the shingle and waste of the limestone
cliffs about Cincinnati. This shell is characterized by its very light
color, horny texture, polished appearance, comparatively few and
little impressed strie, and the aperture of Pilsbry’s juxtidens.
A variety found on Braden Mt. in Campbell Co., Tenn., of very
large size, very much depressed, deeply sculptured and with the
denticles little developed and remote.
A smooth variety from Whitley Co., Ky., with polished surface,
strie very little impressed, aperture nearly circular, almost with-
out denticles.
A variety from Putnam Co., W. Va., very small, with all the
mouth parts approximated, but not like Pilsbry’s fraudu/enta.
This is a most interesting form, and as widely separated from the
last as it well could be.
A variety from Cherokee Co., N. C., with all the characters of
juatidens but with the mouth parts cupped like H. fallaz.
Now I do not hesitate to affirm that in these lots are every gradation
necessary to unite them with the type. This is a matter of the eye simply.
Now what shall we do? Shall we label the first form H. tridentata
polita, the second H. tridentata edentilabris or what not, and so on
to the end, or shall we say for the first H. tridentata Say, var. Cin-
cinnati, O., and for the second H. tridentata Say, var. Campbell Co.,
Tenn.? and so on to the end. The first method loads up our liter-
ature with trinominal designations of varieties that fiz a limit just as
rigid as a specific name. The second method is in accordance with
nature and the facts in the case. They are varieties, uniting each
other, through the gradations in each, with the type. What is a
“ subspecies” ? I undertake to say that there is no such thing in
nature whatever. We may have species; we certainly have no.
“ subspecies.” The moment the specific line is passed, if any exists,
that instant we are in the realm of variations, inhabited only by
varieties. To name these varieties is to make types of them as.
rigid as the specific type itself. If not, why namethem? Ifso, why
THE NAUTILUS. 45
eall them varieties or “ subspecies,” endeavoring in this way to
dodge a dangerous breaker ?
As the humblest student of these beautiful and variable forms of
molluscan life, I shall not cease, upon every opportunity, to enter
vigorous protest against these inversions of the natural order in
development.
As there are no such things in nature as subspecific or varietal
barriers, so there should be none in the literature devoted to her
record.
Here may the educated finer sense, the critical insight, the intense
love of truth, the most unbounded capacity for labor, the acumen
derived from the union and cultivation of all these, find wholesome
employment and scope for all legitimate ambitions.
This is better than erecting obstructions in this highway of the
omnipotent, that must crumble of their own inherent falsity.

ON CHITON HARTWEGII CPR. AND ITS ALLIES.
BY. H. A. BRUSERY.
In the “ Proceedings of the Zoological Society of London” for
1855, Dr. P. P. Carpenter described a number of West American
Chitons, now mostly well-known to western naturalists, among them
C. Hartwegit and C. Nuttall. ‘The descriptions though concise are
excellently worded, leaving no doubt of the exact forms intended ;
for Carpenter was an adept in the art of writing diagnoses. In his
later publications on the shells of this fauna, the systematic position
of these species caused Carpenter some trouble; for he refers them
to both Trachydermon and Chetopleura ; and the difficulty of plac-
ing them in either of these genera caused the present writer to
make anew group, CyaANnopLax (in allusion to the color of the
interior), to contain them. ‘There cannot be much doubt that
Cyanoplax is a subgenus of the Carpenterian genus TRACHYVER-
Mon. The species Hartwegii was founded upon specimens collected
at Monterey by Hartweg (whom Carpenter is pleased to call
“ diligentissimus”). The type measured about 31x19 mm. (1°26x°76
46 THE NAUTILUS.
inch), and agreed in its rather long and narrow form and impressed
sutures with fig. 85 of plate 14 of the Manual of Conchology. —
The Nuttalli (uamed in honor of the naturalist whose name is so
familiar to botanist, conchologist and ornithologist alike) was col-
lected at the same locality, and was stated to differ in being wider,
depressed, the valves squared where they join the girdle, the latter
not projecting between them to form deep sutures. The type meas-
ured about 261x20 mm. This is the form figured by me on pl. 14,
fig. 84 of the Manual.
It is not at all difficult to pick out specimens of this short, broad
form, or of the longer, narrower form, even more pronounced in
character than Carpenter’s types ; but trouble begins when we come
to the intermediate examples. In one lot of 18 specimens recently
received from Miss Shepard, 6 are typical Nuttali; 8 are more or
less typical Hartwegii; but it would puzzle a Philadelphia lawyer
(or conchologist either) to tell what the other specimens are. The
same extremes and intermediates occur in many other trays of
specimens I have seen from various localities; so that one cannot
doubt that the two forms named by Carpenter are merely the varia-
tions of one species, and are not correlated with differences of station
or geographic range.
All of the specimens are dull greenish, gray or even black, the
lighter forms generally having a row of dark blotches on each side
of the dorsal ridge; and seen under a lens, all are minutely but
sharply granulated, with coarser granules scattered irregularly over
and among the smaller ones, especially on the lateral areas; and
they are all rather deep colored ipside, varying from “ Robin-egg ”
to “ Catbird-ege”’ blue.
Some months ago, the writer received from Mr. W. J. Raymond,
fourteen specimens of Cyanoplax, which differ so markedly from the
species discussed above that that they must form a distinct species.
After reaching this conclusion the shells were put aside, for one 1s
slow to describe new littoral shells from so well worked a locality as
middle California; but renewed study of them convinces me of the
necessity of the step.
Trachydermon (Cyanoplax) Raymondi n. sp.

keeled, varying in elevation. Color (1) olivaceous green mottled

sometimes ruddy at the ridge, or (2) uniform blackish, or (3) dark
brown, uniform or with whitish feeks.
Valves rather strong, slightly beaked when unworn, the posterior
(sutural) margins straight orslightly concave. Intermediate valves
rather rounded where they join the girdle, scalloping the inner bor-
der of the latter; not distinctly divided into areas. Lateral areas
hardly or not raised (the diagonal being indistinct) evenly sculptured
with minute, equal granules. Central areas also evenly sculptured
throughout with similar granules, slightly finer on the ridge. End
valves with the same equal sculpture, the tail valve with the mucro
central and a little projecting. .
Interior light blue, with darker stains at bases of the sutural lam-
inz and behind the rather strong blue-white valve callus. Sinus
and sutural lamine asin Hartwegii, Slits in valvei, 8; valves ii—vii,
1-1; valve viii, 11; teeth of end valves blunt, thick, but not distinctly
bilobed. All teeth longer than the narrow, porous eaves.
Girdle narrow, black or with small whitish spots, leathery, very
minutely papillose.
Length 23, breadth 11 mm. (type; San Francisco).
Length 123, breadth 7 mm. (Bolinas specimen).
Habitat, San Francisco, Bolinas, Purissima, San Mateo Co., Mon-
terey, with typical Hartwegit.
Specimens from the first three localities were collected by Mr. W.
J. Raymond, who has seen thein from Monterey also.
This is a longer species than T. dentiens Gld., with heavier valves,
less apparent diagonal, and much longer, thicker teeth. It differs
from JT. Hartwegii (to use Mr. Raymond’s words) in being (a)
“narrower and smaller than southern Hartwegii (Monterey to San
Diego) with which alone I have been able to compare them from
the material at hand; (4) the color of the inside is lighter blue
than in Hartwegii; (c) I cannot make out the warty sculpture,
which you emphasize in the description of Hartwegi.” Moreover,
the teeth are much longer than in Hartwegii, from which the finer,
even granulation well distinguishes T. Raymondi.

in honor of my friend FREDERICK STEARNS of Detroit, who has
contributed so largely to our knowledge of the Japanese fauna.
The specimens vary considerable in length, but not in other char-
acters.

department of Zoology of the New York State Museum (Albany),
has accepted the chair of Biology in Lafayette College, Easton,

REMARKS ON THE STATUS OF SPECIES AND SUBSPECIES.
BY H. A.ILSBRY.
In several articles published in recent issues of this journal, a con-
chologist as well known for his wide experience in the field as for
the vigor and point of his fluent pen, has been at some pains to
criticise certain work by the writer, on American land shells.
Several newly named varieties of well known shells are particularly
obnoxious to my good friend; and in another place’ he attacks the
recent systems of classification of land shells, darkly hinting at
certain tabulated results which he fancies would astonish system-
atists. Now in view of the amount of ink wasted over the questions
of SPECIES, VARIETIES and CLASSIFICATION, it may be worth while
to point out a few of the facts in the case; to show the futility of
arguing on the abstract question of species, and incidentally to call
attention to some of Mr. Wetherby’s mistakes in dealing with cer-
tain varieties described by myself.
Mr. Wetherby says: “we may have species; we certainly have
no subspecies.” Now the truth is that Natwre knows nothing of
“species” or “subspecies,” but only individuals. All groups of in-
dividuals are conventional and artificial. Were the record of palzeon-
tology complete, almost the entire mass of living individuals would
be found to be connected throughout by intermediate forms. Not
only would most of the species intergrade, but the genera, families

50 THE NAUTILUS.
and orders likewise. I say “most” because some would not inter-
grade ; for contrary to the old adage, nature does sometimes jump.
The theory of descent, and the connection of distinct, recent species
by their extinct ancestors being admitted, we may next inquire what
convenient artificial limits may be erected to defined the “ species ;”
for all scientific investigation would be at a stand still if we have no
names whereby to designate the various organisms about us. Prob-
ably the only definition of any use is that a species is any assem-
blage of similar individuals of presumably common ancestry, which
cannot be connected by living intermediate specimens with other
groups of individuals. It is the break in the chain which allows us
to constitute the species; and whether this break be wide or narrow
is of little importance so long as no recent organisms intermediate
in characters are known.” However this idea may be worded, there
is no possible foundation for species on any other basis. Now, many
species, especially those having a wide range of distribution, show in
some parts of their range considerable modifications usually correl-
lated with peculiarities of climate, soil, or other factors known or
unknown of their environment. These modifications are often
sufficient for specific separation were it not for the fact that in some
localities the links connecting the extreme forms occur. We have
here species in process of making, waiting only for the extinction
of the intermediate individuals or for the further intensification of
the differential characters, to become full-fledged specific types. It
is obvious that science must take cognizance of these incipient
species, if itis to be a true record of nature; and for this reason
“ subspecies” or “ varieties” are recognized. Of course they “run
into” each other in some part of their range, otherwise they would
be species. To ignore these varietal forms would be not removing
obstructions from “ the high-way of the Omnipotent ” as Mr. Weth-
erby says, but a piece of the most pedantic falsity. The far-reach-
ing importance of these local or geographic “subspecies” will be re-
cognized when we understand that in them we have the material of
future species in the making. We have moved away from the Dar-
winian conception that species have arisen from favorable variations
of occasional individuals, preserved by the action of natural selec-
tion or “survival of the fittest’? ; and now we see much reason to
believe that the whole mass of individuals over a given area of
changed or changing conditions, is simultaneously remoulded, not

THE NAUTILUS. 51
hy individual variations (which must usually be quickly effaced by
interbreeding with normal or differently modified individuals), but
by the steady action on the entire mass of the factors of climate,
elevation, food-plants, currents and other quantities of the complex
equation unknown to us.’
Mr. Wetherby proposes to avoid the use of subspecific or varietal
names by the circuitous method of writing the /ocality after the
specific name. He would say “ H. tridentata Say, var. Campbell
Co., Tenn.” “ H. tridentata var. Cincinnati, O.” “ H. cereolus var.
Sanford, Fla.” etc. Now the disadvantage of this system is that it.
tells absolutely nothing to the man who has no specimens from those
exact localities, without a detailed description of the shells in each
ease. Moreover, Mr. Wetherby would write “ H. appressa var.
Woodville, Ala.” for both H. appressa perigrapta and H. sargent-
tana, two very dissimilar forms. Who would know which one he
meant to indicate? ‘The trinomial system on the other hand offers
a convenient, concise, readily understood index to geographic and
local races. When one says “P. cereolus septemvolva” the idea is con-
veyed as exactly and much more concisely than by saying “ P.
cereolus large var. St. Augustine,” for unless one has specimens from
this locality he would not then know just what was meant. Again,
were one to say “ P. cereolus small var. Sanford, Fla.” nobody could
tell whether the variety found there was that with an internal lamina
(P. cereolus carpenteriana) or without a lamina (P. cereolus volvowis).
Now what is the use in all this cireumlocution when we have so
convenient a system of nomenclature as the trinomial system,
already in practical use in other departments of zoology.
Having discussed the abstract questions at issue at such length,
we can devote but little space to the particular cases cited by Mr.
Wetherby ; but thisis the less needful because what we wish to estab-
lish is the great importance of subspecies in general, not of any partic-
ular one of our own naming. We may, however, re-affirm the
3One of the most potent causes of specific or varietal differentiation has
been the glacial epoch, which undoubtedly caused a southward movement of
the entire northern fauna. Upon the recession of the ice sheet the species
thus driven south found themselves exposed to changing climate and food-
plants in their new home. Those following the retreat of the ice found the
topography, soil and drainage systems of their former area in the north vastly
changed. What wonder that we find many geographic subspecies! And shall
we shut our eyes to the results upon our snails of the action of these cosmic
forces, these manifestations of the Omnipotent ?

reality of the distinction between the mass of southern, and the
northern specimens of P. appressa. The northern shells described
by Say have no incised spirals whatever, and the upper lip-tooth is
frequently developed. The southern specimens (which we have
called P. appressa perigrapta), have spiral incised lines more or less
developed, and the upper tooth is wanting in the vast majority of
cases. When it is present, as in the Cherokee Co., N. C. examples
mentioned by Mr. Wetherby, I would regard it as an interesting
case of reversion.
As to Polygyra tridentata, Mr. Wetherby has not read my paper
with sufficient care to see my meaning. He attacks my P. fraudu-
lenta, but says in the next sentence that P. fallax is perfectly distinct
from tridentata. The truth is that Helix fallax of Wetherby and
other modern authors and collectors 1s identical with my fraudulenta !
The true H. fallax of Say is identical with H. introferens Bland, as
I have already stated in this journal and elsewhere. So my critic
discredits and affirms the validity ofthis form in one article! As
to P. tridentata edentilabris, Mr. Wetherby has evidently never seen
it. The var. juxtidens is a well-known form. I believe it to be a
distinct line of differentiation, well worth attention and recognition
by name.
I have not referred in this article to the large class of individual
variations such as is shown in the banding of many Helices. This
mode of variation is often repeated, different species having parallel
modifications. The mutations are frequently not inherited, any of
the forms giving birth to numerous others, as is the case with the
band-varieties of Helix nemoralis. This tendency to “sport ” in all
directions is a totally different thing from the moulding of an entire
race explained above; and its products cannot usefully be given
varietal names. They are best expressed by formule devised to
cover entire classes of such variations.
TYPES OF ANODONTA DEJECTA REDISCOVERED.
BY CHAS. T. SIMPSON.
In making a final arrangement of the general collection of Union-
ide of the National Museum I found the other day among some
THE NAUTILUS. 535
Unios, Lewis’ types of Anodonta dejecta. The species was furnished
by Dr. H. C. Yarrow, Surgeon and Naturalist of the Wheeler Ex-
pedition, and was said to have come from the Arkansas or its tributa-
ries, west of the 100th meridian. The lot consists of three broken
valves, two of them forming a normal pair but very much distorted.
I saw in a moment that the shell I named Anodonta mearnsiana
in the Nauriuus, Vol. VI, no. 12, p. 1384 was the same, and my
name will therefore have to be relegated to the synonymy.
Lewis described his species in Field and Forest, Vol.1, nos. 3 and
4, page 26, and in Wheeler’s Report upon Geographical and Geo-
logical Explorations and Surveys West of the One Hundredth Meri-
dian, vol. V, Zoology, p. 952, 1875, but did not figure it.
I am almost certain that the locality given by Dr. Yarrow is
wrong, as the specimens collected by Dr. Mearns were from San
Bernandino Ranch, Arizona, out of waters that drain into the
Colorado River of the West. A very large number of specimens
were sent, and there can be no doubt as to wherethey were found.
It would indeed be a strange thing if this species was obtained
from two places seven or eight hundred miles apart, in two distinct
drainage areas. As the locality given for Lewis’ species is rather
vague, and a large amount of the collections of the Wheeler Expe-
dition were made on the Pacific slope it is quite probable that the
types of 4. dejecta came from the Colorado drainage basin.

DESCRIPTIVE NOTICES OF NEW CHITONS, V.
BY H. SeeeEeeRyY.
Ischnochiton ptychius n. sp.
Shell small, oval, moderately elevated, with fine and distinct
though rather obtuse dorsal keel and slightly convex side-slopes ;
bright flesh-pink, with afew white dots along the sutures, and creamy
angular patches on the outer portions of the pleura of some valves,
the girdle dull flesh-colored with indistinct whitish mottling in some
places.
Median valves short, the posterior outlines slightly concave, with
the beaks but slightly indicated. Lateral areas slightly raised, each
54 THE NAUTILUS.
divided by one curved radial groove in front of the middle of the
area, with one or several shorter, less distinct grooves in front of it ;
concentrically sculptured with coarse, low, irregular wrinkles, which
make the sutural margin feebly dentate. Central areas finely and
minutely sculptured with irregularly zigzag transverse, vermiculate
subgranose wrinkles, which are broken into granules on the ridge,
and are puncticulate, the outer portions of the pleura more coarsely
wrinkled. Valve i having weak radial grooves and concentric
wrinkles. Valve viii with central, low, mucro, the posterior
slope somewhat concave; sculptured like the head-valve but more
obsoletely.
Interior rose-pink, fading to white on the sutural lamine. Sinus
wide, notched at the bases of the sutural laminze; eaves narrow and
distinctly porous. Median valves with 1-1, tail valve 16 slits; teeth
sharp, very distinctly crenulated at the inner edge.
Girdle wide, densely clothed with scales which are weakly
striated, and measure about one-seventh of a millim. in width, and
imbricate inward and backward.
Length 11, breadth 8 mm.
Hab. St. Vincent Gulf (Bednall).
A peculiar little species, shorter than most Australian Ischnochi-
tons, and wrinkled much as in J. striolatus Gray. In the individual
before me there are creamy patches at the outer ends of valves iv,
v, vii and viii; on the last valve there is some olive-green variegation
of the cream color.
Chiton (canaliculatus var. ?) tricostalis, n.
Allied to C. canaliculatus Q. & G. (+insculptus Ad. and stangeri
Rv.) and C. discolor Souv. (-+-miniaceus Cpr.), but having fewer
radial riblets on end valves and lateral areas than the first, and more
elevated than discolor, with projecting, more backward-hooked
mucro on the tail valve.
Shell oblong, elevated, acutely keeled with nearly straight side
slopes. Color variable, either (1) uniform chrome yellow, or (2)
olivaceous mottled finely with white, with some white patches on the
lateral areas, the outer halves of the pleura blackish, girdle oliva-
ceous with cream-white bars opposite the sutures.
Median valves a trifle beaked, the posterior (sutural) margins
nearly straight. Lateral areas well raised, having three radial
tuberculate riblets, the middle one shortest ; tubercles rounded and
spaced on front two ribs, closer and compressed on the posterior rib,
THE NAUTILUS. 55
where they denticulate the sutures. Rarely a fourth very short rib
is indicated on some valves. Central areas having a smooth dorsal
band of about the same width in front and behind, or somewhat
wider in front. Pleura having 14-15 longitudinal riblets, narrower
than their intervals, the inner 1 to 3 on each side not reaching to
the anterior margin of the valve. Head valve with 17-19 radiating
tuberculate ribs. Posterior valve elevated, the mucro projecting,
posterior slope concave. Interior milky bluish, the sutural laminee
white.
Girdle densely clothed with imbricating finely striated scales,
shaped like those of Chiton sinclairt and measuring about one-third
of a millim. in width.
Length 17, breadth 9 mill.; an olivaceous, variegated specimen
is somewhat larger.
Hab. St. Vincent Gulf, 8. Australia (W. T. Bednall).
This form differs from C. muricatus in the shape of the girdle
scales. It is more roughly sculptured than C. canaliculatus, with
the girdle-scales different in form, although they are about the same
width ; and with a different pattern of coloring, although in this
respect all the allied forms of the canaliculatus group vary a good
deal. The smooth dorsal band is wider than in canaliculatus.
It is somewhat doubtful whether this should be considered a geo-
graphic variety of the New Zealand species or an independent
species. It is at all events closely allied to the C. canaliculatus,
although actual connecting links between the two are unknown to
me. The detail figures given in volume xiv of the Manual of Con-
chology (pl. 36, f. 4, 6) excellently represent the sculpture of C.
canaliculatus, being drawn from a specimen furnished by Professor
Hutton.
Chiton ereus var. calliozona n. var.
Shell oblong, elevated, the dorsal ridge acutely keeled, side-slopes
straight; light olive-green, with a few concentric lighter streaks
upon each valve, and obscure dusky-green longitudinal streaks on
each side of valves ii and vi, less conspicuous on iii and v. __ Poste-
rior (sutural) margin of valves i to vii articulated or tessellated,
being painted with alternate white and brown oblique spots. Girdle
buff, paler on the outer half of its width, variegated with transverse
bars of crimson and black scales mingled with the buff ones; about 10
bars on each side.
56 THE NAUTILUS.
Median valves scarcely beaked, the posterior outline of each con-
cave. Lateral areas raised, sculptured with two or three radial
grooves, becoming more numerous toward the bases, and inconspic-
uous growth-striz. Central areas having a wide smooth triangle in
the middle ; sculptured in front of each diagonal slope with narrow,.
spaced impressed longitudinal grooves, not half as wide as the inter-
vals, and which form a sculptured band, increasing but little in
width outwards. Toward the beaks of each valve these grooves dis-
appear entirely, but are replaced by distinctly painted green lines,
very curiously simulating the grooves. Anterior valve with about
28 convex radial riblets, some split at base. Posterior valve with
subcentral subprominent mucro, and slightly concave posterior
slope, weakly radiated. Interior pale blue, the sutural laminze
white. Sinus very narrow.
Girdle densely clothed with very convex, shining, polished solid
scales, those in the middle of its breadth largest, measuring, six-tenths.
mill. in width.
Length 38, breadth 18 mill. (exclusive of girdle).
Hab. St. Vincent Gulf (W. T. Bednall).
I have not much doubt that this shell is a form of Reeve’s ereus,
but the coloration is different, the number of riblets on the pleara is
not nearly so great. Mr. E. A. Smith has united ereus to the Mediter-
ranean C. siculus (=olivaceus), but I can hardly endorse such a
lumping of forms from totally different areas.
ISAIAH GREEGOR.
We have heard with deep regret of the death of Mr. Isaiah
Greegor, which occurred on the 26th of July at his home, Cuyahoja
Falls, Ohio.
Mr. Greegor was not only an extensive dealer in shells, but also:
an ardent and earnest Conchological student. Though for many
years engaged in a business requiring strict attention and skilful
management, he never allowed this to interfere with the promptings
of his generous heart ; a fact which was constantly exemplified by
his timely suggestions and gifts of specimens to friends and others
engaged in Conchological pursuits. He also took much interest in
the completion of the American Association’s collection. His last
barr ~
THE NAUTILUS. 57
gift to this,—some two months ago, wasa number of Florida species ;
among them a suite of Strombus alatus Gmel., remarkable for their
very large size and brilliant coloring; the latter ranging from the
brightest crimson to the deepest purple. The presentation of this
suite gave him a great deal of pleasure, and we shall never forget
his gratified expression when he saw them safely placed.
How little did he then think that his eyes rested upon them for
the last time!

NOTES AND NEWS.
TRACHYDERMON RAymonpt! IN British CotumBia.—Mr. C. F.
Newcombe has found this species abundant at Victoria, on exposed
headlands, its stations being similar to those of the Nuttallinas. It
was formerly confused by collectors of that district with T’r. dentiens,
young Mopalia lignosa, and young Nuttallina scabra. The occur-
rence of the latter species in British Columbia is extremely doubt-
ful. Trachydermon raymondi will probably prove to have the dis-
tribution of Nuttallina californica, Ischnochiton mertensti and Ton-
wella lineata.
Nore ON ORTHALICUS MELANOCHEILUS FLORIDENSIS.—In the
reference to Land and F. W. Shells, N. A. (foot of p. 38) “ fig. 371”
should be omitted. That figure represents a shell from the Sierra
Madra, and shows the conspicuous dark oblique stripe in the aperture
characteristic of typical melanocheilus, and the spirals are very faint
there. A good figure of the Florida shell has been given by Mr.
Binney in “ Fourth Supplement T. M. V,” pl. 2, f. 4.
AGRIOLIMAX CAMPESTRIS IN NEw Mexico.—Mr. A. Boyle has
given me a specimen of Agriolimax campestris which he found in his
garden at Santa Fé, about 7100 ft. above sea level. The specimen
is pale brown, with a pale grey unicoloroussole. So far as I know,
this is the first slug recorded from New Mexico.—T. D. A. Cockerell.

in preserving Anodons. No matter how good they may be, they
won't stay so if they can only get to split up in pieces. Last
spring a fish pond here was drained and I obtained a good lot of
very fine large Anodonta fluviatilis. I washed them clean on
Saturday and put them aside to dry, and when I came back
Monday morning they were having a regular “pic-nic” splitting
and popping. So I just gave them a bath of thin white shellac and
alcohol and they have been behaving well ever since. I send you
some specimens that you may see the effect it has on them.
Frank Burns, Washington, D. C.
[The specimens are still in good condition, and the plan is worth
a further trial. The principle is that the shellac forms an impervious
layer over the epidermis, preventing that evaporation of water from
the latter which causes it to contract and break the thin calcareous
layer. The shellac should therefore be applied as soon as the
surface of the mussel is dry. Its main disadvantage is in the arti-
ficial gloss which it gives the shell, which would prevent its use on
lusterless specimens. If the shellac is very thin it does not effect
the appearance of glossy shells like A. fluviatilis —ED. |
Errata.—A typographical error occurred in the July number of
the Nauritus and I desire to correct same. In the article “My
Daily Walk” on page 34, the second line under the list of species
collected, I notice the ninth word should have read as “ county ” and
not “ country.”— Williard M. Wood.

Dr. Wm. H. Dau has recently issued a “ MonoGRAPH OF THE
Genus GNATHODON, Gray (Rayeia Desm.).” In this essay the
priority of the name G'nathodon for the group is demonstrated ; the
anatomy of both soft and hard parts is described, and the species are
discussed and figured. Dall concludes that Gnathodon does not con-
stitute a distinct family near Cyrenide, as Fischer has it, but that it
belongs without doubt to Mactride and is probably an off-shoot from
the Mulinia stock. The range of the genus is “Subtropical Amer-
ica, the Gulfs of California and Mexico, in shoal quiet water, vary-
ing from salt to fresh, but preferably somewhat brackish; range in
time from the newer Miocene to recent seas.” Three sections are
adopted, Gnathodon typical, Miorungia Dall and Rangianella Conr.
G. cuneatus Gray is the commonest species in collections (often under
the name Rangia cyrenoides).

new to science. These are, however, only slight varieties of well
known species. Among other peculiarities of this strange fauna he
notes four marked modifications, due to their environment, in which
they differ from the types in the waters from which these mains are
supplied. These are: [1] A diminution of size, due to the absence
of light ; [2] a decrease of marked coloration, due to the same cause .
[3] decided modifications of form, generally producing a lengthened
shell, due to the mechanical action of a steady and rapid current ;
[4] difference of general appearance, the polished, brilliant shell
being developed with regularity in a constant medium. The last
two peculiarities may be noticed in the shell life of those streams in
tropical countries which in the shaded mountains are constant; as

differentiated from the formation and appearance of members of the
same species found in the periodic streams of the open plains, which
disappear with each recurrence of the dry season.
ON THE JAMAICAN SPECIES OF VERONICELLA, by Prof. T. D. A.
Cockerell and R. R. Larkin. (Journ. of Malac. III, pt. 2, 1894).
The material discussed in this paper consists of 18 specimens, all
referred to V. sloanii, from Jamaica. These were dissected and
their characters carefully noted. The conclusions reached are of
much value to investigators of this dificult genus. “The results
obtained are quite remarkable and tend to throw doubt on the
validity of several characters hitherto used for the separation of
species in the genus * * * The specimens show great differences
from one another, so that by selecting a few of the most distinct
forms, several apparently good species might be described. Yet we
believe that the whole series represents the variations of but one
species, V. sloanw, and that V. virgata Ckll. must be reduced to
V. sloanti var. virgata. * * notwithstanding so much variability,
the species as now defined should be easy of recognition. The
following characters appear to be quite constant and of specific
value in V. sloanit. (1) The under-side is always free from spots
or markings of any kind, whereas occidentalis Gldg. from the Lesser
Antilles, has some spots below. (2) The sole never projects from
behind the body, as it does in one or two of the continental species.
(3) The filiform glands are less than 10 mill. long, whereas in
dissimilis and floridanus they are considerable longer. (4) The
penis is always long, cylindrical, with the end slightly bulbous and
the orifice terminal. It thus entirely differs from that of such
species as V. portoricensis. (5) The filiform glands are always
more than 10 in number thus differing from V. morchii and V. dubia,
(6) The female orifice is always post median, thus differing from
the continental V. nigra, ete.”
The characters of size and shape, distance of female orifice from
head and sole, size of penis and splitting of its retractor, number
and length of filiform glands etc., were found to vary within wide
limits, and their several variations were not correllated in the
different organs, so that no dependence could be placed upon the
various combinations presented for specific distinctions. Color,
contrary to the opinion of some authors, seems useful in some cases.
The whole series examined is systematically tabulated; and the
only thing lacking in this admirable paper is ilustration. Still,
this is a lazy complaint when all is so clearly described.

THE AMERICAN SPECIES OF CARYCHIUM.
BY HENRY A. PILSBRY.
The genus Carychium contains some of the smallest land mollusks
known. The shell is cylindrical or high conical like that of Pupa,
but the lack of eye-stalks and the form of the lingual teeth show the
genus to belong to the family Awriculide, a group best known in
America by the salt-marsh inhabiting Melampus. The species of
Carychium, like other Auriculide, are terrestrial in habit, living
among damp leaves or wood. The genus contains about 15 recent
species, distributed over nearly the whole northern hemisphere.
In Tot Navriuus for 1891, vol. iv, p. 109, the writer gave a brief
notice of the United States forms of the genus. Subsequent study
resulted in a synopsis of the group, which was published in Proc.
Acad. Nat. Sci., Phila., 1891, p. 318, with plate xiv. With a view of
enlisting the services of conchologists in the needed examination of
more material from various parts of the country, this synopsis is
here reprinted. Information is needed to establish the range of the
various forms, particularly in the West and South, and also the
variations of the several forms. Only the collection of specimens
from points geographically intermediate between the extremes of the
range of this genus, and the examination of such material by a
competent person, can finally decide the question of the number of
naturally defined species, and which, if any of them, must be con-
sidered geographic races or sub-species.

NOTE ON HELCIONISCUS NIGRISQUAMATUS REEVE, SP.
BY GEO. W, TAYLOR.
I have recently received from Mr. Frederick Stearns of Detroit a
number of shells collected by himself and labelled as follows :
“ Patella boninensis, Bonin oa
“ Patella stearnswn.”
“ Patella near stearnsu, Japan, 1892, only 8 found.”
“ Patella nigrisquamata (?), Loo Choo Is., Yacyama Is.”
‘« Patella nagrisquamata (?), a var., Japan, 1892.”
All the specimens sent are, in my opinion, referable to a single spe-
cies which has long had a place in my cabinet as H. nigrisquamatus
Reeve.
Reeve’s locality for this species was “ Australia,’ but this has
never been confirmed and is doubtless an error. The same I think
must be said of the additional locality, “Concepcion Chili,” given
by Mr. Pilsbry Gin the Manual, XIII, 126), on the authority of Dr.
W.S. W. Ruschenberger, for we cannot concede to any limpet a
range so extensive as from Japan to Chili, and Japanese shells of
which I am now writing are certainly true nigrisquamatus if figures
and descriptions count for anything. I may add as negative evi-
dence of a certain value that of several thousands of limpets from
Chilian and Australian localities that have passed through my
hands, I have never seen a specimen, young or old, approaching
this species.
With regard to P. boninensis, the differences on which Mr. Pils-
bry relies are 3 in number (see Man. Conch. XIII, 182). The first
geographical; but as nigrisquamatns has ‘pet. been found in the same
habitat as the original specimens of boninensis this distinction no
—}-
longer holds. Secondly, the size of the central callus; but such a_
difference would hardly be specific, taken by itself, I should think,
and moreover, it is not apparent in the series before me. Lastly,
Mr. Pilsbry notes the brown streaks diverging from the head seg-
ment of the central callus. These marks, however, are present in
some of the specimens sent as nigrisquamata and absent in others
sent as boninensis, showing either that the original collector was un-
able to separate his shells accurately or else that the distinction is
not a constant one,

THE NAUTILUS. 67
As to P. stearnsii, if the shells sent to me by Mr. Stearns are con-
specific with the type specimens named and figured (from his col-
lection) by Mr. Pilsbry, then in my opinion stearnsii is only a
young form of nigrisquamata and J suspect (from the description)
that Patella grata of Gould is the same shell. I am, therefore, in-
clined to write:
Helcioniscus nigrisquamatus Reeve (Patella), 1854.

PEROSTYLUS, THE EMBRYO OF MEGALATRACTUS.
BY H. A, PILSBRY.
In a former number of this journal (June, 1894) the writer
proposed a new genus, Perosty/us, for the Cerithium (Colina) bra-
zieri Tryon and another supposed new species. Upon the appear-
ance of the paper describing these forms, I was informed by my en-
cyclopedic friend, Professor Theodore Gill that the type of the new
group had been shown by Professor R. Tate to be the embryonic
portion of “ Fusus” proboscidiferus. Some time after, the article by
Tate, published in the Proc. Linnean Society of New South Waies
(Australia), Second Series, Vol. VIII, pt. 2,’ p. 244, came to hand.
In reference to Cerithium ( Colina) Brazieri, Professor Tate writes :
“The above named gastropodous shell is described in Tryon’s Manual
of Conchology, Vol. IX, p. 142, and illustrated t. 26, fig. 16. The oc-
currence of Colina in the Eocene beds of Victoria has led me toa study
of the recent species, and in doing so I was arrested by the unlike-

1Mr. Taylor is unquestionably right im considering Helcioniscus boninensis
a synonym of nigrisqwamatus Ry. I had satisfied myself of this by the exam-
ination of the National Museum collection some years ago. He errs, how-
ever, in placing H. stearnsii in the same category as it is a totally distinct
thing. Mr. Taylor probably had the young H. nigrisquamata before him, as
so acute an observer could hardly confuse s/earnsii with the other species.—

ness of Tryon’s figure, as above quoted, to other members of the
genus; moreover, the shell seemed familiar to me, and if I am
right in my identification it is nothing more than the embryo of
Fusus proboscidiferus, of which I have examples from Port Essing-
ton. The apical whorls of that shell are often decollated, but in
some specimens there remains sufficient of the apex to permit one to
arrive at the opinion just stated.”
If any further evidence is needed to demonstrate the true nature
of Perostylus, it is supplied by Mr. Edgar A. Smith of the British
Museum (Natural History), who writes to me as follows:
“The presence of a fine series of Fusus proboscidiferus Lamarck
in the British Museum Collection, ranging from the very young
state up to the adult form, enables me to show that Perostylus is
merely the apical portion of the spire of that immense West and
North Australian shell.
“The late Capt. Beckett brought from the Dampier Archipelago
a number of specimens of this species besides a fine mass of the egg-
capsules containing the young shells in large numbers. These
agree exactly with the description and figure of P. brazieri (Tryon)
and P. fordianus Pilsbry, as given by the latter author. The num-
ber of whorls in specimens from the same compartment of the
mass of capsules is variable from four to six, and the length of
the rostrum and canal is also subject to slight variation. Some
specimens are also considerably broader than others. We have in
the museum collection a specimen corresponding in size with Swain-
son’s figure’ of Fusus aruanus (=probocidiferus) with the apical
whorls still remaining intact. Another example is nine inches in
length and still retains the nucleus, but in all the larger shells this
part is broken off.’
“The apical portion of Turbinella pyrum is also very similar,
but a close examination reveals the incipient characteristic ‘colu-
mellar folds.
“Tn the description of Perostylus the apex is said to be decollated
like that of Rumina or Cylindrella. Whether this is really the
the case has yet to be proved by further observation. There cer-
tainly is every appearance of there having been an embryonic shell
which has become detached, but it is also certain that this takes

place within the egg-capsule, at an early stage of the creature’s ex-
istence, for no such nucleus is attached to any of the specimens in
the egg-capsules at hand which are of the same size as the shells fig-
ured by Mr. Pilsbry.”
In conclusion it should be stated that Fusus proboscidiferus has
been made the type of Megalatractus, a subgenus of Hemifusus
(Semifusus Fischer !), by Fischer. There are good reasons for giv-
ing the group generic rank. It certainly does not belong to Fusus,
the embryonic whorls being very different from those of the typical
species of that genus. Neither can it be referred to Hemifusus as
Fischer has done.’ Perostylus will, of course, become a synonym of
Fischer’s group.

The time in making this collection embraces a number of years
and I think it to be rather complete, having left no stone (or log)
unturned in searching for the species. Mesodon albolabris and thy-
roides are dwarfed, and Tachea nemoralis does not compare as to
size with those from Europe. ‘The sea air may have something to
do with this. The soil is of a sandy nature, as a rule, not adapted
to the growth of sand snails.

GENERAL NOTES.
Wirsn the cooler weather of autumn conchologists will find in-
door operations once more agreeable, and all who have availed
themselves of the past season for adding to their knowledge of mol-
lusk life or to their cabinets of specimens should try to share their
harvests with others by telling of the interesting experiences in the
field, of the occurrence of uncommon species or varieties, or the
turning up of well known ones in new localities. Frequently ran-
dom observations on the life habits of one or a few species are valu-
able. Who knows where most of our marine or land snails lay their
eggs, how many there are, their form and size? And yet thisisa
vital point in the life of the species; and there are hundreds of
others, some of which are sure to come to the knowledge of every
collector. The difficulty is that such facts are too often esteemed of
less worth than a fine lot of shells, and so are forgotten and left half
seen or unrecorded. A collector’s note-book should be as valuable
as his cabinet, especially if the knack of sketching living animals,
etc., is cultivated.
We hope that each of our readers will give us some fact or ob-
servation which has been made his or her own, during the past
summer. Short notes dealing with single topics are always wel-
come, and have the advantage of being published promptly. Such
a magazine as this one is always co-operative, and the more each
gives, the more each receives. If anything you have seen interests
you it is likely to be of value to others: but being interested one’s
self is a good test of what makes good reading. Meantime the edi-
tors will try do their part. In future, more attention will be given to
notices of current literature of conchology than has been our custom
in the past ; and it is of course understood that our pages are freely
open to all opinions, entirely regardless of those held by ourselves.
Tue Junior Epiror of the Naurizus will be away from Phila-
delphia for some time after the middle of October, as he contem-
plates a paleontological trip to Alabama.
Nore on HeEtix Gosser.—As the identity of this species is some-
what obscure, it may be well to clear it upin this place. Helix
gossei was first described by Pfeiffer in the Proc. Zool]. Soc. Lond.,
for 1846, p. 37, the description being repeated in Monographia, I,
p- 30. In the later Conchylien Cabinet, Helix, p. 219, Pfeiffer de-

clared it to be a mere color variety of H. subconica C. B. Ad., de-
scribed in 1845, and the figure he gives of his type amply confirms
this opinion. In the Conchylien Cabinet, a few pages further on,
Pfeiffer describes and figures a “ Helix gossei C. B. Adams MSS.”
This name, of course, cannot stand, being preoccupied by that prior
H, gossei of Pfeiffer himself, and this decision is not affected by the
fact that Pfeiffer’s first gossei isasynonym. This gossei of (C. B.
Ad.) Pfr., I consider a race or variety of H. nemoraloides C. B. Ad.,
1845, and it is practically covered by C. B. Adams’ H. pulchrior,
1851. It is this form which caused Messrs. Simpson and Hender-
son some trouble in Naurinus for May, 1894, p.5. The conclu-
sion is that neither of the “ gosseis” can stand, the first gossei of
Pfr. being a synonym of subconica, and gossei C. B. Ad. MS. of Pfr.
(later) becoming a synonym of H. nemoraloides var. pulchrior.—

HELICES CARRIED BY BIRDS.—“ From the throat of Rallus pec-
toralis Mr. J. A. Thorpe of the Australian Museum extracted the
snail I now exhibit. This is a specimen of Ch/oritis jervisensis
Quoy and Gaimard, a species common in this neighborhood, whose
almost adult and uninjured shell measures 18 mm. in diameter, and
which weighed, shell and animal together, 1:26 grammes. When
found by Mr. Thorpe, to whom I am indebted for both facts and
specimen, the snail was quite dead; as a test I immersed the ani-
mal in strong spirits without inducing contraction ; since, however,
its consumer had been killed forty hours earlier, the suffocation of
the mollusc was to be expected. The bird was shot at Randwick,
near Sydney, on the 19th May, 1894, by Mr. Newcombe, Deputy
Registrar-General. In enumerating “ Means of Dispersal,” Dar-
win observes (Origin of Species, 6th ed. p. 372): ‘A bird in this
interval [eighteen hours] might easily be blown to the distance of
500 miles, aud hawks are known to look out for tired birds, and
the contents of their torn crops might thus readily get scattered.’
In view of the above incident, this suggests a means whereby the
geographical range of jervisensis might be considerably extended.”

DESCRIPTION OF A NEW SPECIES OF DORIDIUM FROM
PUGET SOUND.
BY W. HeebpALEL.
Among specimens of mollusks collected in Puget Sound by the
Young Naturalists’ Association of Seattle, Wash., and forwarded
for identification by Prof. O. B. Johnson,was a species of Doridium,
a genus new to the region, and detected by Miss Adella M. Parker,
in whose honor, at the request of the society, it has been named.
The specimens were dredged in 30 fathoms at Eagle Harbor, Puget
Sound.
Doridium adelle n. sp.
Animal] naked, about 16 mm. long, of a dark plum color, mottled
with fine vermiculate spots of golden yellow; general form that of
D. carnosum Cuvier, but with a shorter velum, half as long as the
body and transversely truncate behind; the posterior free portion of
the mantle short, obscurely bilobed, and without a flagellum ; front
edge of the velum slightly excavated; parapodia wide, the sole
slightly longer than the body; shell internal, subconical, white
covered with a brownish epidermis; pillar strong, reflected with a
deep grove outside of it, the basal end projecting spur-like; nucleus
small, depressed.
The shell is more conical and the eycloid wall of it narrower than
in D. carnosum, and the excavated pillar much more prominent.

EDITORIAL CORRESPONDENCE FROM ALABAMA.
The following paragraphs from a letter received from the junior
Editor of the NautiLus, written from Claiborne, Alabama, under
date of Oct. 18th, will be of interest to our readers :
«3 %* T arrived here [Claiborne] last evening, seven days
out from Selma. While waiting fora train at Selma, I took a stroll
along the river. The steep bank of bluish gray clay, probably forty
or fifty feet in height, tempted me to look for fossils. A small
Ostrea, or Gryphea, a Pecten resembling Camptonectes burlington-
ensis, and several parts of a large Inoceramus told me it was creta-
ceous. But the specimens were too scarce and poor to warrant the
expenditure of much time. From Selma I went by train to Catha-
rine, and thence to Prairie Bluff.
“Tt is at the latter place that the collector of cretaceous fossils is
in his element. The bluff is over one hundred feet high, and in one
place slopes gradually, giving one a good opportunity to collect.
Fine large specimens of Exogyra costata and Gryphea vesicularis
were abundant. The shells of the latter were unusually thick and
the lower valve very convex. Perfect specimens of Plicatula urti-
cosa were also common. Finely preserved casts and, in many cases,
the shells of numerous species of Gastropods, were abundant. Ex-
ceptionally numerous were: Anchura spirata, Turritella encrinoides,
Rostellites texturatus, Pyropsis sp.,Natica abyssina and Lunatia Halli.
Of the Cephalopods, I found Nautilus DeKayi, Baculites ovatus and
Ammonites sp., in fair numbers.
“At Matthew’s Landing, ten miles below Prairie Bluff, is the first
good exposure of strata containing Kocene fossils. They are well
preserved and very interesting, many that I found being new to the
Philadelphia collection, Cardita, Arca, Volutilithes, Pleurotoma,
being some of the principal genera. I found the spire of a large
and handsome conch, reminding one of Melongena corona, except
that the projections on the angles of the whorls are nodulose instead
of spinose, but I looked in vain for a perfect specimen.
On the west bank of the river, a short distance below Clifton,
are high bluffs of indurated blue clay, and I found the first (and
THE NAUTILUS. 15
last, so far) Strepomatide of the trip, Goniobasis solidula Lea. The
bank below the water-line was covered with them. In many places
little springs trickled down the bank, and in these they were to be
found to a height of twelve feet above the river level. Notwithstand-
ing the very low stage of the river, I have seen no living Unionide,
and only a few worn and faded valves on Burford’s Bar.
“Tn the the bluff at Peach Tree there is a narrow stratum of
ferrugineous sand containing a few Eocene fossils. Monday, the
15th, was spent at Gregg’s Landing, four miles below Peach Tree.
As there were no accommodations there for staying over night, we
made every minute tell. It is a fascinating spot; great masses of
a hard fossiliferous sandstone in which Turritella mortoni and Ostrea
compressirostris predominate, and which has come from an upper
stratum seventy or eighty feet above the present water-line,
lay strewn along the base of the cliff, reminding one of Potomac
Creek, Va. In the lower fossiliferous stratum, of a dark, indurate,
sandy clay, Cardita planicosta, Cucullea sp., Turritella humerosa,
Turritella sp. and Calyptrephora trinodosa, were the conspicuous
ous forms.
“ Bell’s Landing, five miles below Gregg’s, was next visited.
The fossils were similar to those found at Gregg’s, but among them
were many rare species—rare in collections and rare at Bell’s
Landing.
“Tt was indeed singular how many uniques of some very inter-
esting forms I found here. The stratum referred to above was also
present here, but the upper one was for the most part a soft sand,
and contained a greater number of species. As it was impossible to
work the upper stratum in place, and as both were mixed together
in the talus at the base of the cliff, I found it impracticable to
keep the fossils of the two separate. JI have not had time to hunt
for land shells, but from. appearances it seems somewhat unfavor-
able. On the bluffs it is extremely dry, while the lowlands are
subject to overflow. To-morrow I go to work at the Claiborne
fossils. Yours sincerely,
“Cuas. W. JOHNSON.”
POLYGYRA (STENOTREMA) HIRSUTA ON LONG ISLAND.
BY A. H. GARDNER, FORT HAMILTON, L.I., N. Y.
In the October number of the Nauriuus I noted a catalogue of
the land shells of Long Island, N. Y., by Mr. Henry Prime, which
76 THE NAUTILUS.
seems, from my own investigations, to be very accurate. I venture,
however, to supplement the same with a species hitherto unrecorded
amongst the annals of the mollusk fauna of Long Island, and exist-
ing in what I believe to be a very circumscribed area. Most of the
species Mr. Prime records I have found in localities other than those
he names, and from his more extended investigations and those of
his predecessors, Messrs. Temple Prime and Sanderson Smith—
ranging over nearly the entire island—I am inclined to believe that
the species of which I am about to write is to be found in but one
locality, the one in which it was first discovered.
During the early spring of 1891 a colony of Stenotrema hirsuta
was accidentally discovered by my friend, the late Mr. James Arm-
strong, a naturalist residing in Bay Ridge, L. I.; they were found in
a small patch of woods, or rather, a small thicket, laying at right
angles to a good-sized wood, at what is now 13th Ave. and 74th St.,
Brooklyn. The situation was a good one, being shady, and the
ground covered with small fragments of boulders cast there at some
past time from the surrounding fields. It had been undisturbed
for years, as the position of the stones testified to; the leaves of
many summers had fallen, decayed, and left their remains amongst
the interstices in the form of a rich, dark mould.
The surrounding woods, for there are (or were) several in this
immediate vicinity, had been thoroughly searched, both by myself
and Mr. Armstrong, for many previous years, with a view of col-
lecting specimens of the land mollusca, and had yielded to active
and close search examples of Helix (Mesodon) albolabris and
thyroides, Zonites arboreas and indentatus, Helicodiscus lineatus,
Strobila labyrinthica, Vertigo Bollestana and miliwm, but never a
trace of the Triodopsis or Stenotrema groups, which, moreover, had
never been noticed before .by either of us in Long Island. Steno-
trema hirsuta is at all times a rare shell in this part of the country.
I know but of one specimen, collected at Highbridge, N. Y. City,
and have heard of a few specimens being found on Staten Island
by the late Dr. Hibbard, on the palisades of New Jersey. I have
found them, but even there they are exceedingly scarce.
Now in this particular locality they abounded, and a very large
quantity of specimens was procured.
The question arises how or by what means were they introduced.
Evidently they were not the survivors of a species that had once
flourished there, as in that case at least dead shells would have

been found elsewhere near the locality. The large quantities found
would point to their having been native to the place for a long
period of time. Why they had notspread is not strange when their
habits are considered: they are slow in movement and retiring,
loving to adhere to the under side of a stone, where moisture can
be procured in the hot days of summer. Surrounded by conditions
favorable to their existence, they neither seek nor require change
of locality.
It is easy to account for the introduction in any place of a new
plant or insect. The influence of the wind will scatter spores or
seed vessels over a vast area; whilst when the locomotive powers of
insects are considered, both aerial and terrestrial, it needs but a
new condition, generally the scarcity of food, to cause an immediate
migration, bounded only by arrival at the nearest spot indicated by
instinct as the place where more suitable conditions exist, necessary
to the preserval of life and development. But in the case of a
snail, and especially such a slow moving one as S. hirsuta, it is
different ; to such an organism transition over an extended distance
would be an impossibility, that is to say, by its own natural
powers.
The only theory possible to solve this question is that they were
carried there either as snails or the spawn of snails by some out-
side influence which we can only attribute to a winged animal
capable of covering an extended distance continuously ; for exam-
ple, a hawk or other bird of strong flight may have left the Pali-
sades of the Hudson river with dirt adhering to its claws containing
the embryo “hirsuta,” and winging its way across river and Jand,
alighted on a tree at this spot, and in the process of perching,
scraped off dirt and snail spawn, which dropped amongst the stones
below. And again, the bird may have swallowed the 8S. hirsuta,
and asit is a globular shell and of very hard substance, it may have
escaped the grinding of the stones in the cesophagus, passed through
the digestive organs, and been ejected at the locality with other
excrement, and there perpetuated the species.
At any rate, this appears the only agency by which the species
can have been introduced, and unless the same can be distinctly
refuted, it forms a theory illustrated by the present example of the
diffusion of certain furms of molluscan life over a continent—an
agency probably uncommon and rarely put in force by the strange
workings of Mother Nature.
78 THE NAUTILUS.
N. B.—This locality has been recently invaded by civilization in
the form of an electric road passing near it, bringing its attendant
blessings (?), houses and their inhabitants. But as yet the colony
exists; I collected specimens there as lately as last September.
EASTPORT NOTES.
BY REV. HENRY W. WINKLEY.
Chiton marmoreus Fab.
A variety differing from the type in size and color occurs at
Eastport. The type occurs in size as long as 14 inches, and even a
trifle more than that. The blue variety is not over an inch,
the average being about ? of an inch. The type has the color -
of the interior white at the edges of the valves, deepening to rose
color. In the variety, which may be called var. cwruleus, the rose
color gives place to a delicate light blue. The outside is robin’s
ege blue. Though not common, this variety seems to be established.
I have found it twice, and in small numbers.
Bucinum undatum Linn.
The type is abundant at Eastport. Largest specimen, 2% inches.
(I have a specimen from near Old Orchard 4 inches long.) A vari-
ety (v. plana) occurs at Eastport and Grand Manan; size of largest
specimen, 1% inches, resembling the type except in size and loss of
waves. In some cases the waves remain in faint form; in some
cases they are absent altogether. The type form at Eastport has
the waves very heavy.
Margarita undulata Say.
Type is abundant; an albino form occurs rarely ; it is about one-
half the size of the type.
Terebratulina septemtrionals (young), Menestho albula and a
few of the deep water starfishes were found at low tide in small
numbers.
Astarte crebricostata—formerly common in 10 fathoms, could not
be found.
THE NAUTILUS. 79
The season has been a good one for collecting at Eastport. Some
of the rare forms, like Lunatia grenlandica and Bela Pingelii, were
found at 15 fathoms, and on the whole, there was a tendency among
the deep water forms to the shallower water.
THE HABITS OF FLORIDA LITTORAL MOLLUSKS,
BY JOSEPH WILLCOX.
Although the following facts may be well known to some Con-
chologists, there are many undoubtedly who have not had the oppor-
tunity of observing the habits of southern shells. It is a very inter-
esting scene to witness the actions of many mollusks in the shoal
waters in the bays of Florida, and on the sand flats that are ex-
posed to the air at low tide. Below is a list of some of the shells
that are found above the water level at low tide on the southwest
coast of Florida:
Fulgur perversum, Aplysia,
F. pyrum, Sigaretus perspectivus,
Oysters, Callista gigantea,
Oliva literata, Nassa vibex,
Fasciolaria gigantea, Marginella apicina,
F. tulipa, Melongena corona,
F. distans, Conus proteus,
Cerithium atratum, C. Floridanus,
C. nigricans, Cardium isocardia,
C. muscarum, Cardium magnum,
Cerithidea scalariformis, C. muricatum,
Lucina Floridana.
Aplysias do not remain voluntarily out of water at low tide, as
they then become dry on the surface and appear to suffer for want
of water, often emitting in such cases a large amount of purple
fluid. They possess no power of locomotion on Jand.
The Cerithium usually crawl about on the sand soon after the
water has receded, and remain above the surface until the return of
80 THE NAUTILUS.
the tide. Their tracks may often be traced more than twenty
feet.
Cerithidea scalariformis habitually crawls up the stems of grass,
and lives the greater portion of the time out of water.
The Cerithium nigricans live in large colonies between high and:
low water marks.
Cardium isocardia crawls out of the sand soon after the water dis-:
appears; but they do not travel far. When put ina basin of salt.
water, they often close their shells with a lively snap.
Fasciolaria distansis the only shell, observed by the writer, which
feeds upon the Vermetus nigricans colonies, into the tubes of which
it inserts a long proboscis.
Fasciolaria tulipa is the only shell, in the knowledge of the wri-
ter, which makes an effort for freedom when held in the hand. It
projects its body out of the shell and “slashes ” about its long and
sharp operculum with sufficient force to occasionally bring into view
some of the blood of its captors.
The Oliva lterata often lives in colonies. It emerges from the
sand soon after the disappearance of the water, and crawls for a
considerable distance.
Sigaretus lives usually under the sand, but at low tide it often
comes to the surface; but it does not proceed far. It is a favorite
morsel for the ‘littoral pigs,” who root it out of the sand with
avidity.
Lucina jamaicensis affects the muddy sand. They lie deeply
buried under the surface, and seldom are seen on top of the mud.
The Lucina tigrina probably possesses the same habit, as many dead
shells are found in places where few are seen living.
The Pholas costata, I presume, lives below low water mark, as their
shells are washed ashore in some places in great quantities. They
also live in colonies in the muddy sand flats that are dry at low
tide.
The shell reposes about 10 to 12 inches below the surface, but
the animal can project its long siphon to the surface, through a hole
permanently kept open.
In a future article we propose giving the results of observations
upon the feeding habits of some Florida mollusks.

NEW FORMS OF WESTERN HELICES.
BY HENRY A. PILSBRY.
The Pacific Slope has been proven by the researches of many
collectors to be richer in varietal forms of Helices than any other
part of the United States; but although there are a large number
of well-marked local varieties, there has been a tendancy to over-
split them on differences of no racial value. The following forms
are believed to be sufficiently individualised to require names.
Although superficially some species such as arrosa, tudiculata ete.
are very much like the European group Arionta, others like Cam-
pylea, and still others from Lower California are like Euparypha,
it is the writers belief that the American forms are not closely allied
to these European groups, but rather to the forms found in Japan,
China and the Philippines, the resemblance to European types being
a case of “convergence” of one character, the shell, and not extending
to the less readily modified viscera. Other allies of the Californian
group are the Hemitrochus of Floridaand the greater Antilles. in
Mexico another allied group, Lysinoe, is found; but the genuine
Californian type extends southward along the mountain axis as far
as the Argentine Republic. All these American, and the East
Asiatic groups are more nearly allied to each other than any of
them are to the European Helices.
The earliest name for this group of forms is the rather cumber-
some term Epiphragmophora of Doring; and it is proposed to use
this in a generic sense, to supercede Arionta, Aglaiaand Euparypha
of American writers. The history of all these snails and their
names, with a discussion of their probable ancestry and migrations,
will be found in the writer’s Guide to Helices, now in press.
Epiphragmophora ellipsostoma 2. sp.
Shell globose-depressed, with low-convex spire, round periphery
and almost covered umbilicus; thin ; colora greenish straw tint, with
one supra-peripheral brown band, surface shining, showing irregular
growth wrinkles, and closely, somewhat spirally wrinkle-malleate
all over, much as in the thin forms of E. tudiculata; the spiral
tendency of the wrinkles more marked below. Whorls 4, the apical
1} forming a rather large nuclear shell; last whorl deeply descend-
ing in front, a little constricted behind the basal lip. Aperture
very oblique, short-elliptical, obliquely truncated by the penultimate
whorl; peristome rather narrowly but evenly and well reflexed

throughout, dilated at the columella insertion and almost covering
the umbilicus. Alt. 12°5, greater diam. 20, lesser 16°2 mm.
Belongs to the E. rowelli group, but differs from other species in
its malleation. From tudiculata and its allies, it differs widely in
the elliptical mouth, coarse apex and fewer whorls. The same
characters and its sculpture remove this shell from E. traskii and
its several varieties described by Hemphill.
Locality, “San Juan del Norte” (Gabb). Probably on the east
coast of Lower California.
NOTES AND NEWS.
VARIATIONS OF PLEUROCERA ALVEARE Conrad.—In L, and
F.-W. Shells, part 4, (Strepomatide), page 50, Mr. Tryon says:
“The species is very variable in length,” leading one to infer that
the other features were more constant. Such is not the case.
Specimens from Cypress and Shoal creeks, Ala., present such a
difference that on first sight the mature shells of one stream would
not be taken for the same species as those from the other.
From Cypress creek they have the folds or tubercles on each
whorl and the striz on the base well defined. From Shoal creek
they are eroded on the spire, giving the shell a cylindrical appear-
ance; body whorl smooth and the striz of the base faint or want-
ing; a number from both streams are two-banded ; the upper band
causes the dark spots Mr. Lea mentions in his description of perno-
dosa. In both streams they were found on rocks in the current.—

RECENT PUBLICATIONS.
Ospras MALAcoLocicas DE J. G. HipateGo. Madrid, 1894.
The name of Joaquin GonzaLez Hrpaua@o has long been a fam-
iliar one to conchologists acquainted with recent French and Spanish
literature of mollusca; and whoever has used the more extended
works “ Moluscos Marinos de Espana, Portugal y las Baleares” and
the “ Moluscos Terrestres,’—works indispensable in the study of the
shells of Southwestern Europe—will hear with pleasure of the pub-
lication of the “ Obras Malacologicas.” This magnum opus, of which
several parts lie before us, will consist of three portions: works re-
lating to the fauna of Spain, works upon the South American fauna
and publications on the land shells of the Philippine Islands. Of
the former two we may judge in advance by the magnificently illus-
trated volumes named above, and the “ Moluscos del Viaje al
Pacifico.”
That upon the Philippine fauna, now in course of publication, aims
to present asummary of the literature of each species, with valuable
critical notes on the variations, distribution, etc.; and it is illus-
trated ona scale which leaves little to be desired. The land snails
of the Philippines are among the most beautiful of any region, and
it is only fair to say that for the first time justice is done them in the
splendid plates of Hidalgo’s Obras. The Helices and Cochlostylas
are illustrated in the parts already issued, and we hope to have the
Bulimi and operculates before long. The text is characterized by its
moderate and conservative spirit, refreshingly free from “ nouvelle
ecole” vagaries, but well abreast of the times.
84 | THE NAUTILUS.
The work will doubtiess be of the greatest assistance to all students
of this rich fauna, and we hope that its talented and industrious
author may succeed in bringing it to a good completion.

A CONTRIBUTION TO A KNOWLEDGE OF INDIANA MOLLUSCA,
by R. Ellsworth Call (from Proc. Ind. Acad. Sci., III). The pres-
ent paper is a preliminary list of the Indiana mollusk fauna, show-
ing what has already been done toward an exact knowledge of the
conchology of: that State. Only authentic locality references are
given, and nothing is admitted to the list on the strength of its
occurrence in neighboring States. Of land shells, 58 species are
enumerated ; fresh-water univalves, 47 species; bivalves, 102 spe-
cies. No less than 53 species were originally described from Indiana
localities. A bibliography is given, both of special and general
works bearing on Indiana shells. The “ Contribution” is a step in
the right direction, and will be welcomed by both Indiana collectors
and those interested in the distribution of United States shells
generally.
Notes oN THE MIOCENE AND PLIOCENE oF Gay Heap, MAr-
THA’s VINEYARD, Mass., ETc., by W. H. Dall (Amer. Jour. Sci.,
Oct., 1894). The result of Dall’s visit to this locality, examined
by Lyell 50 years ago, and by numerous other geologists later, are
important, verifying its reference to Miocene, in which it corre-
sponds to the Chesapeake, “in all probability to the upper part of
the Chesapeake, certainly not lower than the St. Mary’s fauna, and
probably between that and the Yorktown beds.” At about 80 feet
above sea level a small patch of shell fragments was found, in a
stratum of sand, which is considered Pliocene. Nucula shaleri and
Macoma lyelli are described as new from the Miocene; and Chry-
sodomus stonei Pilsbry, originally described from stray specimens
washed ashore on the New Jersey coast, was found, thus fixing its
position, hitherto unknown, in the Miocene.

A SHELL HUNT FORTY FEET UNDER THE SEA.
BY C. HEDLEY, SYDNEY, AUSTRALIA.
To widen the fairway of Port Jackson (Australia), a submarine
reef is being removed. An opportunity of going down with the
divers employed thereon was kindly offered to myself and a scien-
tific friend by the officer in charge of the operations. So tempting
an invitation was, of course, accepted with delight. Often in im-
agination had we wandered on the ocean floor, peering into ghastly
wrecks of ships sunk long ago, fighting with some huge shark or
monstrous octopus, and gathering treasures of science or heaps of
gold. Now our dreams were to come true and we were indeed to
tread that fairy-land. We might not have the luck of the mariner
in the song who
‘“« Fell overboard in a gale,
And found down below where the seaweeds grow,
Such a lovely maid with a tail,”
but we should certainly pluck strange growths at the bottom of the
sea as one might pick flowers in a meadow.
A trim launch sped with us from Circular Quay down the famous
Sydney Harbor, past bay after bay, some lined with wharves and
shipping and some with trees growing to the water’s edge, by rocks
and white sandy beaches, past point and headland gay with villas
and gardens, or sombre with eucalypt forest. So familiar was the
86 THE NAUTILUS.
scene to us, that we smoked and chatted, unmindful of its beauties,
till we reached a flotilla of punts and barges moored near the Heads.
After a cup of tea with the overseer, we prepared for our descent
by divesting ourselves of boots, coat, vest and collar. A couple of
laborers officiated as my valets de chambre, wrapping me first in
thick flannel socks, trousers and jacket, and then in a canvas over-
all garment which left only the head and hands uncovered. The
hands being left bare, the sleeves were secured at the wrists by rub-
ber cuffs and bracelets. My feet were thrust into a pair of enor-
mous boots, each sole of which was weighted with 25 pounds of
lead. Bending my head, two men placed over it a huge diver’s
helmet and screwed it into a brass collar of the canvas dress. My
costume completed by slinging on chest and back two large metal
weights, I was told to rise. Thus encumbered, it was no slight ex-
ertion to get up, take three steps to the ladder, and descend into the
water knee-deep. There I halted while my signal cord was belted
round my waist ; my air-tube, which reminded me of a garden hose,
was screwed to my helmet and the pump commenced to force air
through it. Finally an attendant screwed a plate-glass front, the
size of a saucer, into my helmet; from the inside, this last operation
resembled the closing of a coffin-lid. Some one tapped my helmet
twice, the submarine signal for “all’s well,” and I started.
Stepping off the bottom rung of the short ladder, down I went,
till the keel of the barge loomed up, rose and passed me—down,
down into the green sea water, watching the silvery bubbles stream
upward—down, down, down, as the water darkened. That sensa-
tion of gliding down into an emerald abyss, was the weirdest, dream-
iest thing I ever felt. Then so gently did I alight, that I merely
noticed that I had ceased to fall. At my feet I saw rock and sand
and seaweed ; looking up, I saw a monster in a helmet with two
ropes leading away up to where the sky ought to be. The monster’s
face showed through his little window as a big, fair moustache and
a pair of kindly blue eyes. Fetching out of a capacious trouser
pocket a small school slate, he wrote, “ How do you feel? Shall we
goon?” and held it up. Taking his slate, I wrote, First rate; go
on.” He read the message, gravely rubbed the slate clean with his
finger, pocketed it, and held out his hand. I grasped it and we
started for a walk at the bottom of the sea.
Then I noticed a pain in my ears; the compressed air was hurt-
ing me. ‘To cure it, I went through the motion of swallowing once
THE NAUTILUS. 87
or twice. Feeling more comfortable, I “began to take notice,” as
they say of the babies. The light was bright enough to see small
things plainly twenty feet away, but the water strangely magnified
familiar objects. A shoal of little fish passed us, swimming under
our arms and between our legs in the most ridiculous way. I tried
to take one with my hand, but it deftly turned and avoided my
grasp. The guide, seeing my attempt, pinned one to the ground
with an iron rod he carried, and handed it to me; another he
stabbed and caught as it swam by. Before we had gone far I had
lost all sense of time, space or direction, and became too confused to
know whether I had travelled east or west, ten yards or a hundred,
in ten minutes or half an hour. A queer sensation was that of hay-
ing escaped from the law of gravity; it seemed just as easy to walk
up as down a cliff—we usually walked on our toes, sloping from the
ground at an angle of forty to sixty degrees. When too much air
is pumped down, the submarine pedestrian is unduly buoyant, and
his aims to clutch a shell from the ground must be comically like
the dodging and staggering of a drunken man.
A little dell lay before us choked with rank seaweed, through
which we strode waist-deep like plunging into a tangle of fern in -
some damp valley on the land. My guide reached out, picked some-
thing off a broad frond, and handed it to me. It was a Doris, a
lovely creature, whose like I never saw in books, striped with purple
on a milk-white ground. It began to crawl over my fingers quite
unconcernedly. I clapped my hands and tried dumbly to express my
delight by patting my companion’s big fist. He replied by offering
me the slate, on which I wrote, ‘“ Very good; put him in the bottle.”
Rubbing out my words, he wrote, “Send down the bottle,” tied the
slate to the rope and jerked the latter four times. Away went rope
and slate to the regions above. In response to an answering signal,
the slack was hauled in.and my collecting-jar descended tied to the
rope. In turn, we tried in vain to open it. Although our corre-
spondent above had filled the bottle with water, the pressure at our
depth so sealed it that we could not raise the stopper. With a mes-
sage on the slate, “Open this bottle and send it down open,” we
sent the jar aloft. When is was lowered to us the second time, I
found that my Doris had slipped unobserved through my fingers,
and so I lost a possible new species, the rarest treasure I was to see
that day.
88 THE NAUTILUS.
Continuing our travels in the dim water-world, we passed through
a field of sponges. Not the brown, round masses of the bath-room,
but radiant growths of scarlet (Raphyrus hixoni and Halicondria
rubra) and purple, here and there great open oscula, tempting one
to poke in a mischievous finger. Some grew in tufts like moss, some:
expanded like a dainty vase (Phyllosiphonia caliciformis), some
forked like branches of trees and some spread like a lady’s fan.
One abundant species, about the size and shape of an orange, was
pure ice-white, studded with golden dots that almost glittered (Leu-
condra sp.). Of all these we gathered what we could, pricking our
hands sore with sponge spicules as we worked. When, on the mor-
row, our ravished beauties lay dead on a table in the museum, they
had faded sadly from their pristine splendor. Among the sponges.
grew purple Boltenia pachydermatina, a pear-shaped head upon a
slender stalk, like tulips in an earthly garden.
For a surprise, the diver held up before my face and pressed an
Aplysia. From it flowed a violet stream which stained the water
for two feet around, hiding hand and mollusk in the cloud. One of
my last captures was an exquisite nudibranch, which swarmed on
the broad fucus blades. In hue it was the blue of a summer sky,
~ flecked with blood-red dots and stripes. J had now grown weary ;
not of searching for wonders, but of supporting the heavy diving
armor, and was content to be drawn up again to the world of air
and sunshine, which I had quitted three-quarters of an hour before.
On reflection, I found the reward of my under-water foray to be,.
not a hoard of specimens, but a better appreciation of the circum-
stances under which marine life exists. Our party of four had only
observed, dead or alive, Chamostrea albida, Vola fumata, Trigonia
lamarcki, Struthiolaria scutulata, Drillia oweni, Cassis pyrum, Cyprea
zanthodon, Astralium tentoriforme, Ranella leucostoma,A plysia kerau-
dreni, Chromodoris bennetti, and two undetermined Doris. Mol-
lusean life seemed, on the spot I explored, to be less plentiful than
at low-tide mark. Perhaps, however, the difficulties under which I
labored as a beginner in the art of diving, impeded me from finding
what was really there. After seeing the rough sea floor, one won-
ders that a dredge should capture as much as it does. A rich harvest.
probably awaits a conchologist who should seriously practice diving
as a means of collecting.
THE NAUTILUS. 89
VERTIGO MORSEI, n. sp.
BY DR. V. STERKI.
Shell large (for the group), cylindrical-turriculate, with a rather
acute apex, imperforate rimate, with few obsolete striae of growth,
shining, translucent; whorls six, rather slowly and regularly in-
creasing, the last scarcely higher than the penultimate and rather
narrower, somewhat sloping towards the base, slightly ascending at
the aperture ; suture deep; aperture lateral, scarcely oblique, com-
paratively small, inferior and palatal part well-rounded, the laster
with an angular impression and slightly protracted in about its
middle, the upper half more strongly curved, peristome everted ; on
the palatal wall, at some distance from and parallel with the mar-
gin, a moderate crest, behind it a deep and large impression over
the palatal folds, and in front of it a groove corresponding with the
impression at the auricle ; inside the crest there is a distinct callus
of the same color as the shell; apertural lamellae and folds typic-
ally nine: three on the parietal wall (the same as in JV. ovata), the
largest whitish ; two on the columella, the superior strong, vertical
above, then in an angle turning horizontally, the inferior horizontal,
lamelliform, thin, high and directed obliquely upward ; basal small,
sometimes double, rarely 0; palatals high, and rather long, curved
and directed upward; suprapalatal small, nodule-like.
Size: alt. 2°7, diam. 1:3; apert. alt. 0°9, lat 0°8 mill.
Soft parts not examined.
Habitat: Kent County, Michigan.
This magnificent Vertigo has been collected by Dr. DeCamp and
kindly sent for examination by Mr. Bryant Walker. There were
seven specimens, all fully mature, well-formed and almost exactly
alike. Yet there are some slight differences, as they may be found
in all forms of this group: in one example the inferior parietal tooth
is wanting, in another the basal only trace-like, and in a third the
same is double, as frequently found in V.ovata. With the latter
species, V. morsei has much resemblance, especially in the aperture :
the configuration and the “teeth” are the same, but the inferior
columellar, and the two principal parietals, are rather larger, and
markedly directed upward. ‘he main difference is in the number
and relative size of the whorls: while in V. ovata they are five, and
rapidly increasing, the last predominating; in our species there are
six, slowly increasing, the last, and consequently the aperture, com-

paratively small. This is a radical difference, and gives the shell
quite another aspect, so that there can be no question about its being
distinct. But V. morsei is also decidedly larger, V. ovata not, or
little, exceeding two millimers of altitude.
The species is named in honor of Mr. E. 8. Morse, who has so
considerably promoted our knowledge of the Pupidae.

Lepidopleurus percrassus n. sp.
Shell solid, strong, small, of a pale pinkish-brown with a darker
brownish girdle which appears rather narrow in the dry state ; scales
very minute, partly dehiscent, chaffy, with occasional slender
spinules resembling hairs; scales on the base crowded, minute,
sandy; an extension of the girdle is prolonged between the valves
on each side as far the jugum, the surface of these sinuses is also
minutely scaly with occasional spinules ; valves thick, white below,
moderately arched with the prominent jugum forming a sort of keel ;
near the points of insertion the valves are heavily callous below;
the sutural laminz are short, smooth and separated at the median
sinus by a prolongation of the jugum in advance of the anterior
margins of the pleure ; sculpture of the jugum consisting of punc-
tate fore-and-aft parallel grooves with some small elevated transverse
ridges anteriorly ; the rest of the valve has, on each side, six or
eight vermicular ridges divaricating toward the posterior edge of
the valye and irregularly corrugated with sharp, fine, elevated

lamelle crossing the interspaces transversely but fading out on the
ridges; head-valve with minutely nodulous concentric ridges; tail-
valve highest at the subcentral, not very prominent mucro, in front
sculptured like the intermediate valves, behind the mucro like the
head-valve. Length about 14, width 5°75, height 2°5 mm., in the
dry state. The dry girdle about half a millimeter wide.
Specimens obtained by Mr. T. S. Oldroyd from a stone pulled up
from about 75 fathoms in the Santa Barbara Channel off San Pedro,
California.
This species, for which a section named in honor of Mr. Oldroyd
is proposed, is very remarkable. The girdle recalls that of Deshayes-
iella Carpenter, but is extended in such a manner as to partly sep-
arate the shelly portions of the valves. The very callous surfaces of
the interior, according to Mr. Pilsbry, are unique in the group.
Most of the species of Lepidopleurus are comparatively thin, and
though Z. cajetanus is a solid shell, none of the species are as heavy
as the present one in proportion to their size. The conspicuous and
forwardly produced jugum is unique in the family. The type is in
the National Museum, and will be figured later.
PATELLA (HELCIONISCUS) NIGRISQUAMATA REEVE.
BY CHAS. T. SIMPSON.
In the collection of the National Museum are twenty specimens
of Patella bearing the above name received from Frederick Stearns,
the U. S. Exploring Expedition, W. K. Fischer, and the Lea-
Chamberlain Collection—the latter credited to “ Dr. R.” by Mr.
Lea, and probably from Ruschenberger. One other specimen of the
same name is in the museum from the Rich Collection without lo-
cality.
These vary from young shells less than an inch in diameter to
those which are more than 3} inches in length. There can be no
doubt that the above name is correct, as all the specimens agree
fairly well with Reeves’ description and excellent figures in the
Cohchologia Iconica (Vol. VIL, Patella, species 3, plate II, figs.
3* and 3°).
The species described as P. boninensis in the Nauritus (Nov.,
1891, p. 79), was characterized by its author as having a large cen-
tral muscular callus, and two diverging dark bands from the an-
erior head segment.
92 THE NAUTILUS.
Our large series shows every possible variation in the develop-
ment of these characters, from young specimens in which no scar or
tails (for they look very much like squirrel tails) are visible, to old,
solid shells with a heavy, snowy, swollen callus, and having these
brown wings very strongly developed.
The same characters are seen in Patella (Helcioniscus) argentata
Sowb., better known as P. talcosa Gld. H. clypeater, which Mr.
Pilsbry places with Nacella, on account of slight differences in.
anatomical characters, but which, conchologically, seems closely
allied to P. argentata, and in other species.
In short, there can be no doubt that this scar and the curious
radiating brown lines are merely adult characters which are de-
veloped in quite a number of species. I quite agree with Mr. Geo.
W. Taylor in believing that this species does not come from the west
coast of South America, but is probably confined to the north-west-
ern part of the Indo-Pacific region.
THE VIRGINIA COLONY OF HELIX NEMORALIS.
BY T. D. A. COCKERELL, N. M. AGR. EXP. STA.
There appeared in the Nauriuus, of Nov., 1889, a paper under
the above title, setting forth some very interesting facts regarding
the variations exhibited by a colony of H. nemoralis at Lexington,
Va. Prof. J. H. Morrison, who collected the shells studied, took
considerable interest in the matter at that time, and had gathered
together a good deal of information additional to that given in the
above-cited paper. I have, therefore, been quite disappointed: not
to see any publication by him on this subject, or any evidence that
the colony has received further attention.
It is scarcely necessary to dwell on the extreme interest attaching
to the history of this colony. Here we have a variable species in-
troduced into a new country, and varying in a most extraordinary
manner under the influence of the new environment. The peculiar
variations are very numerous, though, in the main, tending entirely
in one direction—to the splitting of the normal bands. Although
the number of individuals thus varying is considerable, very few of
such have exactly the same formula, whereas, several of the old
European variations occur in numerous specimens.
It appears, in the highest degree, probable that these peculiar
variations are congenital and not acquired during the lifetime of
THE NAUTILUS. 93
the individual,’ in which case we have an example of environment
modifying the germ-plasm—the odds against the variation being
only accidentally coincident with the changed environment being
» enormous.
In 1889, the above-mentioned changes had taken place in the
colony, but time was needed to show whether they would increase
in number and degree; or whether, as seemed more probable, the
old European varieties would eventually assert themselves, and
swamp the rest. In either case, the result would be very interest-
ing, and now that five years have elapsed, it is extremely desirable
that some one should make a new investigation and report in detail.
It is really astonishing that no one has yet done so. The colony
was, in 1889, so evidently in a condition of unstable equilibrium,
that it seems certain that changes must have occurred in the inter-
val, tending to the predominance either of the old or the new (split-
band) type.
Believing that Prof. Morrison would publish, I did not follow my
paper of 1889 with further observations, but it will be as well now
to put the following on record :

that it is split, but joins near the mouth of the shell.
NOTES AND NEWS.
Mr. T. WAYLAND VAUGHAN is now engaged in geological work
on the scientific corps of the U.S. Geological Survey.
Mr. GitBert D. Harris, formerly of the U.S. Geological Sur-
vey, has, after spending the summer abroad, taken up the work of.
his new appointment at Cornell University, where the valuable col-
lection of mollusks, of which Dr. Newcomb was so long curator, is
under his charge, as well as the Paleontological Department.
Tae Lone Breacu (CALIFORNIA) CONCHOLOGICAL CLUB elected
the following officers for the next year: Miss I. M. Shepard, Presi-
dent ; Mrs. M. Darling, Vice-President; Mrs. Terry, Treasurer and
Secretary, with Miss E. Lowe her assistant.
The Club is to hold its meetings twice a month. The following
are the charter members: Miss E. Lowe, Mrs. M. Darling, Mrs. E.
Cushman, Mrs. R. Preston, Mrs. Terry, Mrs. Craig, Miss I. M.
Shepard and Mrs. Dial. At the next meeting, to be held Decem-
ber 1, new members will be received. The Club has been studying
and collecting for a year, but had not before formally organized.
They held their first Annual Meeting and Reception at the home
of Miss E. Lowe, on the evening of October 6. A short program
was given and letters of greeting read from Dr. W. H. Dall, Mr.
H. Hemphill and Prof. Josiah Keep. Ice cream and cake were
served in shells, and the rooms handsomely decorated with palms,
shells, kelp, and smilax.
The Club would be glad to hear from any and all interested in the
same study, and will make a special study and collection of our
local shells or shells of Los Angeles Co.
AMNICOLA OLIVACEA Pits.—In April, I visited the original lo-

cality (Huntsville, Ala.) and was surprised to find this species in
vast numbers. The stream has a mud bottom which is much in-
dented with cow tracks. In these the Amnicola had congregated—
not as a layer on the surface, but as a solid mass. To get an idea
of how many there were I scooped up the contents of three holes,
and after washing them thoroughly, found I had a full quart of the
living animals. There must have been bushels of them in the few
rods of stream which I inspected. The stream receives some of the
city sewerage, so it is probably a good feeding-ground.
The geese which infest the neighborhood do not seem to care for
this species. —H. E. Sarcent, in lit.
NEW PUBLICATIONS.
THE Lire AND WRITINGS OF CONSTANTINE SAMUEL RAFINES-
QUE, by Richard Ellsworth Call, is announced to be published in
January next. The volume will be in quarto form, and issued in
paper only. It will contain several full-page illustrations, one of
_ which will be a portrait of its subject. A complete bibliography of
the writings of Rafinesque, on every subject, comprising over four
hundred titles, will be included, together with a certified copy of his
will, one of the most remarkable testamentary documents ever pro-
bated. It will prove of exceptional value to those interested in
botanical, conchological, or ichthyological matters.
A MonoGRraPH OF THE LAND AND FRESHWATER MOLLUSCA OF
THE BririsH IsuxEs, by J. W. Taylor, F. L.S., is announced as in
press. The object in issuing this work is to bring together, as far as
practicable, all reliable information bearing upon the study of the
British Land and Freshwater Mollusca. It will aim to combine
the information upon all aspects of the study, and thus form a
standard work of reference as well as a reliable text-book upon
British Land and Freshwater shells. The first volume will be de-
voted to general characters of the shell, the morphology of the ani-
mal, geological and geographical distribution, habits, parasites, etc.
The second volume will be devoted to the treatment of species in- .
dividually, and will aim to give accurate descriptions and faithfully
colored figures of the typical shell and the chief varieties of every
species; the various organs of the animal will be described and
illustrated in the text, and full lists of localities, with a full syn-
onymy will also be given, as well as observations upon the habits
and peculiarities of each species. Mr. Taylor’s work promises to be
a timely and useful one. Fuller notice will be given upon the ap-
pearance of the first volume.

TWO NEW PISIDIA.
BY DR. V. STERKI.
Pl. II, Figs. 1-13.
Pisidium cruciatum, n.sp. Figs. 1-6, 13, 13a.
Shell minute, inequipartite, oblique, subtriangular in outline,
high, ventricose, regularly and comparatively coarsely striated,
straw colored; anterior part moderately long with an oblique,
nearly straight edge above and the end rounded ; posterior part
short, the end somewhat obliquely truncate, superior margin rather
strongly curved, scutum scarcely, scutellum little marked, the latter
forming a rather distinct angle; inferior part moderately curved ;
beaks prominent, each with two ridges diverging at nearly right
angles, together forming a cross on the upper aspect of the shell,
each of the ridges ending in a nodule of which the posterior is
larger and more prominent; nave rather thick, whitish; hinge
very stout, list strong; cardinal teeth rather large, and strongly pro-
jecting inward from the hinge list; in the right valve one, strongly
curved, posterior part thick, anterior thin, lamellar, the ends united
by a lamella so as to form a deep groove into which the posterior
tooth of the left valve articulates; in the left valve two, the poste-
rior (inferior) stout, massive, the other, superior and a little anterior,
rather short, fine, lamellar, oblique, little curved; lateral teeth
large, high and pointed in the left, strongly projecting inward in
98 THE NAUTILUS.
the right valve, the latter with no (oronly traces of) outer teeth, and
a deep groove; between the cardinal and the lateral teeth the hinge-
list is rather deeply excavated, so that all teeth are markedly isola-
ted; muscle insertions visible ; ligament, short, strong.
Size; long 1°9, alt. 1°9, diam. 1°4 mill.
Soft parts slightly yellowish.
Habitat: Tuscarawas River, at New Philadelphia, Ohio.
Figure 1 represents an adult specimen, 2 the posterior, 3 the dor-
sal aspect, 4-6 a young example, 0°8 mill. long; fig. 13 the hinge;
13a the dorsal aspect of the right cardinal tooth with an indenta-
tion ; figs. 1-6: scale 151.
The singular shape of the umbones is so characteristic that this
species will be recognized at once, and cannot be mistaken for any
other. And also in the formation of the hinge it is quite unlike
any other Pisidum, so that it holds a peculiar position in the genus.
In the hinge structure it is very illustrative and instructive for
the understanding of the different forms of cardinal teeth ; yet this
is not the place to discuss the subject at length.
Our species is rather variable, even so that all specimens from
one place in the river are different in size and shape from those of
another place scarcely half a mile distant. Jt measures from 1-6 to
2°1 mill. (One specimen 2°1:2'1:1°6, another 1°7:1:7:1°3 mill.), 1:9
being about the average; the margins may be rather obtuse or
somewhat acute, the beaks more or less prominent, and the anterior
nodule more or less marked. Asa rule there are no outer lateral
teeth in the right valve, yet traces of them may be seen in some
specimens. Also in the formation of the cardinal teeth there is
some variation, as the one in the right valve may be indented in its
middle, at the angle, and so there are apparently two teeth (fig.
15a).
Pis. cruciatum is not rare in the Tuscarawas River, where, so far,
it has only been found, but probably it has a wider distribution, and
may even have been collected and taken for the young of some other
species, owing to its minute size. In October and November, 1891,
it was first found, and some specimens were sent to several conchol-
ogists, so to Mr. EK. W. Roper, who also recognized it as a new spe-
cies. In 1893 and 1894 about a hundred were collected, in all
stages of growth. Only few of them are quite mature, and almost
globular, most adolescent, and, though apparently old, much less
inflated. They live in mud among aquatic plants and dead leaves,
THE NAUTILUS. 99
and, as a rule, are covered with a black or brown coat, sometimes
so thick that they appear to be globules of dirt, and only a sharp
eye may recognize them from the hair-like free line along the edge.
Some old specimens are badly eroded.
Pisidium punctatum, n. sp. Figs. 7-12.
Shell minute, inequipartite, high, oblique, strongly ventricose,
almost globular, regularly and sharply striated, microscopically
rugulose, whitish; anterior part moderately long, the edge above
oblique, almost straight, end slightly angled, rather inferior ; anterior
part short, truncate, slightly angular above, rounded below; superior
and inferior margins moderately curved, the former rather short,
the latter long; scutum little, scutellum moderately marked, both
forming slight angles; vertical section heart-shaped, horizontal,
short, lanceolate-rrhombic; margins very slightly acute; beaks
moderately full and prominent, with a longitudinal, slightly oblique
ridge (sometimes obsolete) below the culmination ; nave moderately
thick, whitish, with crowded, small pits, from which it appears as if
dotted ; hinge moderately strong; cardinal teeth fine, in the left
valve two, lamellar, longitudinal, about equally long, a little curved,
almost parallel, the upper little anterior; in the right valve one,
longitudinal, little curved, lamellar, the posterior end slightly thick-
ened; lateral teeth rather small and thin, in the left valve one,
pointed, in the right valve two, the outer quite small; hinge-list fine,
rather regularly formed ; ligament rather long and fine.
Size; long 1°8, alt. 1°6, diam. 1°3 mill.
Soft parts colorless, rest whitish.
Habitat: Ohio; Tuscarawas River, Bear Run, tributary to the
Mahoning River, Portage Co., a spring brook at Rootstown Station,
Portage Co., emptying into the Cuyahoga River (Lake Erie and
St. Lawrence drainage) ; in all places collected by the writer.
Figures 7-9 represent an adult, 10 a young specimen, scale
151; fig. 11 the hinge, 11a the dorsal aspect of the cardinal teeth
in the left valve; fig. 12 shows a remarkable abnormity of the car-
dinal tooth in the right valve.
This species resembles somewhat Pis. compressum Prime, in hay-
ing a ridge or appendage, but not in the same place, as it stands on
the outside, below the culmination of the beaks, while in the mature
P. compressum it has its place rather on top. The shape of the
shell is different, and the size is very much smaller, its bulk being
only about one-tenth of that shell. And while the upper part of
100 THE NAUTILUS.
the posterior margin in P. compressum is rounded or flattened, it is
sharp, somewhat “ pinched” in P. punctatum. In this the shell is
purely whitish, or light straw colored, the latter more so when dry,
while the mature P. compressum is always more or less grayish. <A
marked feature is the finely and densely pitted interior surface of the
shell, the dots being distinctly perceptible through the shell from the
outside. Yetthisis not unique, as I havealso seen it in other Pisidia.
Some specimens show not a trace of the appendages on the beaks,
yet they are evidently identical.
In the Tuscarawas River this Pisidium appears to be rare, as
only thirty were taken, twelve of them in one place, in company of
about five hundred P. campressum, most of the latter quite young
to half grown, P. cruciatum and a few P. abditum, which is common
in pools and ditches. More frequent it is in the Bear Run, where
about 120 were collected, but only one-fourth of them adult. Those
from the spring brook mentioned above, are somewhat larger, aver-
aging 2:0 millimeters long.
These two well characterized and very small Pisidia are a valua-
ble addition to our molluscan fauna. Besides them there are several
other undescribed species from our country at hand. These small
mussels have been somewhat neglected and a more assiduous col-
lecting and closer study will doubtless bring to light not only more
unknown forms, but also interesting geographical relations.

HAMINEA VIRESCENS. (Pl. II, fig. 15).
BY MRS. M. F. BRADSHAW.
One afternoon in August, when the low tide of the month occur-
red, we went to our favorite reef of rocks to see what of interest new
or old we could find.
There were acres of mussels with Purpura saxicola in great num-
bers and various colors wedged in between them. ‘These Purpuras
are graceful in form and often beautifully colored and striped, and
I never tire of them. There were several species of Acmea and
Fissurella volcano plentiful enough, and as we reached the outside of
the reef where the waves dashed at us threateningly, we found a
few small Haliotis cracherodii, some seaurchins and starfish. These
THE NAUTILUS. 101
last we left to the enjoyment of their home in the deep pools among
the rocks.
But I wanted to tell you of the real “find” of my summer. On
the flat surface of the rocks, and nearest the shore, were small in-
dentations and shallow crevices. While looking into these in search
of a possible new Chiton, I saw a gray object which I picked up
with the remark that here was some sort of key-hole limpet.
My little companion says: “ What isa key-hole limpet?” and
so I took out my knife and was about to dissect it to give her a les-
son in conchology, but to my ae I found I had something
quite new to myself.
I had very rarely picked up on the beach a small, pale yellow
bubble shell never more than ¢ inch in length, but had no idea
whereabouts this little mollusc had lived. But here in my hand
was a real live Haminea, the pale greenish shell so nearly transpar-
ent, that it was excusable to at first think it was internal instead of
on the creature’s back.
The shell was about inch in length, and as we found none
larger, was probably an adult, and it covered less than one-third of
the mollusk.
The animal itself was a slimy gray globule, not pleasant to touch,
and one could not help wondering what possible use or protection
was this fragile, inconspicuous, insufficient shell.
Further search revealed several dozen, but they were hard to find
even after we knew exactly what to look for, so nearly were they
like their surroundings.
After that we searched for Haminea in all similar places for sev-
eral miles of our coast, but never again found them; so I am still
of the opinion that they are rare in this locality.
Monoceros engonatum is not rare on this coast I believe, but I
never found them until that day, I got two, one a fourth of a mile
from the other. Careful search failed to reveal more, though these
individuals could not be living alone, and I have no doubt had only
taken a short excursion, leaving the rest of their families safely at
home.
The field of my observations has been but limited; situated
about midway between Los Angeles and San Diego, but I think it
is a locality rich in the number of its species.
102 THE NAUTILUS.
NEW FORMS OF AMERICAN SHELLS.
BY H. A. PILSBRY.
Gastrodonta (Pseudohyalina) lateumbilicata n. sp.
Shell resembling Ps. dimatula in color, texture and sculpture, but
much depressed, the upper surface almost flat, last whor] of much
smaller calibre, the umbilicus very much wider, shallow, its cavity
widely open and saucer-shaped, much as in Helicodiscus lineatus.
Alt. 1:4, diam. 4°3 mm.
Hab., near Woodville, Alabama. Coll. by H. E. Sargent, whose
labors in northern Alabama have been remarkably fruitful in
increasing our knowledge of the conchology and mammalogy of
Alabama, as well as in his chosen work as an educator.
Somatogyrus Sargenti n. sp.
About the size of S. aureus Tryon, but shouldered as in S. sub-
globosus Say, and imperforate. Shell globose-turbinate, light olive-
green, smooth except for fine growth lines. Whorls about 44, those
of the spire very convex and separated by deep sutures ; last whorl
shouldered above, flattened toward the suture, large and convex.
Aperture large, ovate, a little flattened on the parietal side, broadly
rounded below, narrowly rounded above, and angular at the upper
insertion of the lip. Columella concave, moderately heavy, the
callus becoming wider at the umbilical region ; parietal wall with
a transparent callus layer. Alt. 6, diam. 5mm. Mud Creek, a
tributary of the Tennessee R., Ala.; coll. by Prof. H. E. Sargent.
This species differs from S. integer and the closely allied species
or varieties depressus, aureus and parvulus in its shouldered whorls,
planulate below the suture. It hasno such heavy columellar callus
as S. currierianus; and it is a smaller species than S. subglobosus
(isogonus) of Say, with wholly closed umbilicus and differently
formed columella.
RANGIA THE PROPER NAME OF THE MACTROID GENUS GNATHODON.
BY THEODORE GILL.
Mr. Dall, in the Naurizus (VIII, 27) and Proc. U. S. Nat.
Mus., (XVII, 91), has shown that the generic name Ginathodon was
wy
THE NAUTILUS. 103
introduced before Rangia for the same genus of Mactroid bivalves.
Nevertheless, the former name must give place to the latter, because
it had been previously used in zoology for a different genus. Ever
since Mr. Dall communicated to me the results of his investigations,
Thad a dim recollection of having seen the name used in another sense,
and that Rangia would have to stand, but could not recall any cir-
cumstances connected with it. Having had occasion recently to
refer to the Plectognath fishes, I recalled that the name Gnathodon
had been given to a combination of the genera Tetrodon and Dio-
don, because neither of the latter was applicable to all the forms of
the composite genus. It was Goldfuss in 1820 who thus used the
name in his “ Handbuch der Zoologie.” I have not access at pres-
ent to a copy of Goldfuss’ work,’ but have verified my recollection
by reference to Cuvier and Valenciennes’ “ Histoire Naturelle des
Poissons,” (1, 226), where, in a summary of the work, the name is
thus mentioned “ Gnathodon (Diodon Tetrodon.)”. Of course, the
name is not active in ichthyology, and, also of course, it is not
recorded in any of the Nomenclators of zoology, but, in accordance
with the law “once a synonym always a synonym,” the previous
application of the name in ichthyology precludes its use in con-
chology.
A NEW VARIETY OF OLIVELLA.
BY JOHN FORD.
Some months azo, I received from my friend, Mrs. E. M. Gay-
lord, of Alameda, Cal., a suite of Olivella which had been found
by her in a box of shells that apparently came direct from the
Gulf of California.
All of the associated species were well known Gulf shells, and as
the Olivella were in the same fresh condition as the rest, there was
no reason to doubt that the entire lot had been secured simultan-

eously, and, probably, at the same locality. In view of this con-
clusion, also of the fact that the specimens are in some respects dis-
tinct from any heretofore known to me, or, so far as I can learn, to
any writer on conchological matters, I assume the responsibility of
naming and describing them as follows :
Olivella gracilis Gray. Var. Gaylordi Ford. PI. II, fig. 14.
Shell similar in outline to O. gracilis, but much smaller, general
color bluish-grey, with a well defined interrupted band of a lead-
black hue bordering the upper part of the final or body whorl.
Smaller spots of a like hue also appear at the upper edge ot the
fasciole. Circling the middle portion of the whorl is a number of
irregular brownish lines, which also occur less prominently on the
fasciole. In some specimens a splotch or two of the same color as
the interrupted band referred to, appears on the upper part of the
preceding whorl. Apex very acute and free from spots. Length of
aperture rather more than one-half that of the shell ; dorsal portion
of the extreme base creamy white. Average length of specimens
9 to 10 mm., width 3°2 to 4mm. MHab., Gulf of California.
Mrs. Gaylord, for whom the variety has been named, is not only
a practical collector, but an unusually earnest and capable con-
chological student also. It gives me great pleasure, therefore, to
associate her name with the beautiful s ecimens referred to.
FERUSSACIA SUBCYLINDRICA AND TWO NEW SPECIES IN JACKSON
CO., ALABAMA.
H. E. SARGENT, WOODVILLE, ALA.
— —_—__———.
The pleasure which thrills the field naturalist upon locating witb
in his range, a species previously unknown to the region, must be
experienced to be appreciated. It is my privilege at this writing
to report three such finds. |
Late last November, at the end of a shell hunt of two hours,
which had among other things brought to light several fine speci-
mens of H. obstricta Say var. y, I chanced to detect for the first
time a specimen of F’. subcylindrica L.
Its station was a flat surface rock about thirty feet square, at an
angle of 30°, with a north exposure. Having a sack with us, my:
THE NAUTILUS. 105
assistant and I proceeded to “bag” the leaf mould. While doing
so another new thing attracted my attention. Upon comparing it
with asingle specimen of Z. limatulus Ward in my collection, I
pronounced it the same with a question and sent it to the Editor for
verification. He writes “ Your dimatulus I find, on comparing with
typical specimens, are much flatter and have wider umbilicus. I
therefore, call them Gastrodonta (Pseudohyalina) lateumbilicata n.
”?
sp.
Daylight failing and being a mile from home in a ravine 500 feet
below home level, and only the bed of a mountain torrent for foot-
path, we could only carelessly collect the bushel of mould which we
brought away, doubtless leaving many specimens. Upon assorting
the material the following was the result:
Ferussacia subcylindrica L., 245. Pomatiopsis lapidaria 48.
Gastrodonta latewmbilicata Pils., 200.
G. capsella Gld., 25. Z. indentatus Say, 18.
G. interna Say, 18. Helicodiscus lineatus Say, 5.
Patula perspectiva Say, 51. Helix spinosa Lea, 1.
H. stenotrema Fer., 3. H1, inflecta Say, 4.
A subsequent visit to another part of the same ravine resulted in
the finding of 50 more specimens of G. dateumbilicata, but none of
F. subeylindrica. I have since received two specimens of the latter
from another locality not far distant.
This trip also resulted in the finding of two living specimens of
Gastrodonta acerra Lewis, the gem of our American Zonites. A
number were also found which had been broken into and eaten.
Query ; may not the rarity of this species be due to its delicate
shell and habit of remaining among the loose leaves rather than
burying itself in the mould as does its more thrifty neighbor
Omphalina laevigata Pfr. ?
This is thus far the only station at which I have found @. weerra.
A new species of Somatogyrus for which the name Somatogyrus
sargenti Pils. is proposed, is found in considerable numbers, twenty
miles northeast of here in a spring, tributary to Mud Creek, which
is in turn tributary to the Tennessee River. It is found attached
to the dead leaves in company with one species each of Physa,
Planorbis, Limnaea and Goniobasis.

The Conchologists Exchange was started so oddly (on a postal
card) and ended so abruptly—and without an index to either vol-

but could not obtain sufficient subscribers to warrant it. We now
propose to print an index of both volumes, if enough of our sub-

Derap Snarts.—On the 14th of last April, (1894), I turned over
a log in the woods in Miami Co., Ohio, and found, all in a heap,
the following shells: 74 adult Helix elevata, 38 young of same, 1
Hi. profunda, 9 H. alternata, 1 H. albolabrisand 2 H. hirsuta, mak-
ing in all 125 individuals. They were all dead but well preserved,
and many were clean inside so that they would make good cabinet
specimens. Besides these perfect shells there were many so broken
that they could not be readily identified.
How can we explain this? Did these mollusks seek the warmth
to be derived from a number huddling together, or were they acted
upon by the common impulse of protection? Were they destroyed
by insects, or did they perish by the cold? The preceding winter
was an unusually mild one, and the size of the log and quantity of
leaves which surrounded them would preclude the latter theory.
The fact that so many were so thoroughly cleaned inside would seem
to show that some insects as ants had made an attack upon them
and eaten them. What are the enemies of our commonsnails? I
have often found perfectly clean dead shells under logs.—G’. D.

108 THE NAUTILUS,
UEBER BINNEN-ConcHyL. der Kiistenzone von Rio Grande do
Sul, von Dr. H. von Ihering.—From the study of land snails found
in Quaternary deposits the conclusion is reached that formerly the
region in question was wooded, and more favorable to snail life
than the present sandy expanse with sparing grass growth. In the
living fauna a remarkable new genus of Succinide occurs, like a
Hyalimaxz with completely internal, spireless shell.
Die SusswassER-BIvALVEN JAPANs, von H. von Ihering (Abh.
Senck. naturforsch. Gesellsch.)—In the discussion of the species,
this work supplements Kobelt’s Fauna Japonica, describing several
new specific forms. Inthe Japanese bivalve fauna, v. Ihering finds
only East Asiatic types, and those occupying the entire Holarctic
tract (such as Margaritana margaritifera). There are no peculiar
forms of more than specific value, the fauna being merely a part of
that of the adjacent Siberian and Chinese countries, unspecialized
except in the specific characters, and many of the species are very
near those of the mainland. It is interesting to find that these
results coincide with the facts known in regard to the freshwater
gastropods and the land shells. Except that the mollusk fauna of
Japan has a more southern aspect than that of the adjacent main-
Jand (due to the warm ocean current, the “ Gulf stream of Japan”),
there is no difference of any importance in zoogeography.

A GLANCE AT THE CHICAGO ACADEMY OF SCIENCES.
BY FRANK C. BAKER, SECRETARY.
In 1857, a society for the promotion of science, was formed in
Chicago, taking the name of “ The Chicago Academy of Natural
Sciences.” About $1.500 was subseribed, a room taken in the
Saloon Building, corner of Clark and Lake Streets, a few cases were
made, and a museum was begun. In 1859, the society was incorpor-
ated by the name of “ The Chicago Academy of Sciences.”
In the winter of 1863-4, several prominent citizens of Chicago
resolved to found a Scientific Museum in the Metropolis of the
Northwest. A large sum of money was accordingly subscribed, an
Act of Incorporation, (1865) as now published, was obtained and
the Academy was placed upon a solid foundation. Mr. Robert
Kennicott was appointed first Director of the Museum. Collections
rapidly rolled in and rooms were taken at the Metropolitan Build-
ing, corner of Randolph and La Salle Streets. In 1865 Mr. Kenni-
cott, with a party of young naturalists went to Alaska to survey a
route for a telegraph line, then proposed to connect North Amer-
ica with Russia. From this expedition Mr. Kennicott never re-
turned. He died suddenly of heart failure on the banks of the
Yukon River. After the death of Mr. Kennicott, Dr. William
Stimpson was appointed Director of the Museum.
June 7, 1866, the building in which the Museum was placed was
partially destroyed by fire. The collections were much damaged,
110 THE NAUTILUS.
and parts were wholly destroyed. This calamity brought the ques-
tion of a permanent building to head, and a lot on Wabash Ave-
nue, north of Van Buren Street was purchased and a fire-proof
building erected. The first meeting was held January 28, 1868.
The building was of brick 55 feet by 50 in area, and 50 feet high ;
the floors were of brick and iron the stairways and principal doors
of iron, and the windows were covered with iron shutters. The base-
ment was used for laboratory and storeroom ; the first floor for
library and offices, while the whole upper part, surrounded by two
wide galleries, was occupied by Museum. From this time until the
great fire the growth of the Academy, under the skillful manage-
ment of Dr. Stimpson was rapid, and much valuable original work
was done.
On the 9th of October, 1871, this building, in spite of the fire-
proof qualities which it was supposed to possess, was totally de-
stroyed in the great conflagration which laid Chicago in ashes,—
specimens, library, manuscripts, and apparatus—all that was left of
the once invaluable collections was a sheet of printed paper and a
few pieces of broken pottery. Within twelve days after the fire,
however, a meeting was held and steps taken towards a restoration
of the Academy. A circular was issued inviting the sympathy and
help of corresponding societies, which elicited many immediate and
liberal responses. The loss of his priceless manuscripts so prostrated
Dr. Stimpson that he died on the 26th of May, 1872.
It was soon determined to rebuild upon the old site, and upon the
same plan modified by such improvements as experience could sug-
gest. Upon the front of the same lot a business block of the first
class, four stories in height was erected. The restored building was
occupied in the fall of 1873. The funds at the disposal of the
Academy being insufficient for their needs, they borrowed such ad-
ditional sums as were necessary, securing the lender by a mortgage
upon the whole property. ‘They estimated that the income from the
property would provide a sinking fund by which the original indebt-
edness would be paid when it became due. The scheme, however,
proved disastrous. The new building did not pay the interest on
the indebtedness, and after a term of years, in process of law, the
whole property was lost to the Academy.
When, in 1886, the Academy was finally driven from its home on
Wabash Avenue, the Exposition Company received the collections
within its building upon the lake front and paid the expense of their
THE NAUTILUS. 111i
maintenance. But in its turn, the exposition company was ousted
and its building destroyed. The property of the Academy was sent
to storage where it remained for several years. In 1891 when the
affairs of the Academy seemed to have reached their lowest ebb, a
proposition was made to unite its fortunes with the University of
Chicago, then just organizing. This the Academy was not willing
to do, feeling that in time the identity of the organization would be-
come lost in that of the University. In 1892 a generous citizen of
Chicago Mr. Matthew Laflin, seconded and aided by his son George
K. Laflin promised to give a sum adequate for the purpose of erect-
ing a building which should stand for all time as the home of the
Academy. In addition to this, it was ascertained that it was pos-
sible for the commissioners of Lincoln Park to aid in the prosecution
of such an enterprise by offering a site and additional endowment.
The result is one of the most perfect museum buildings situated in
one of the most beautiful parks in the world. In June, 1893, the
corner stone was laid and Nov. 1, 1894, the building was formally
thrown open to the public.
The new building is a plain rectangular structure measuring 159
by 50 feet. The material of the building is Bedford stone and the
architecture is Romanesque. Over the central] doorway is the in-
scription MatrHew Lariin Memorrau. The interior is decorated
in old gold and ivory giving a soft tone to the light. There is electric-
ity, running water, electric bells, elevator, and all the modern im-
provements which go to make up a perfect museum.
The library contains 5000 scientific works. It communicates with
the museum by two stairways. The museum hall is 150x50x30 feet,
with one wide gallery. Upon the main floor there are 24 large
eases, in the gallery the same number with the addition of a large
rail case. Unlike most museums there is not a dark corner in the
building, from cellar to garret.
The collections consist for the most part, of North American pro-
ductions, and are most complete so far as the valley of the Mississippi
is concerned. In Mollusca, the collection is rich in North American
forms.
With a new building and the best of facilities, it is believed that
the Academy will again occupy a prominent place among Scientific
bodies, and regain the prestige and fulfil the promise of its earlier
days.
Tt2 THE NAUTILUS.
ON A NEW SPECIES OF HOLOSPIRA FROM TEXAS.
BY WM. H. DALL.
Holospira pasonis n. sp.
Shell white, mostly smooth but hardly glossy, of eleven and a
half whorls; two and a half smooth, inflated, nepionic whorls, the
apex flatttsh, followed by several whorls which are minutely ribbed
in harmony with the incremental lines, the ribbing gradually becom-
ing obsolete over most of the shell but reappearing on the last whorl,
especially the basal part, sharper and somewhat crowded just behind
the reflected lip ; umbilicus closed or reduced to a minute chink ;
suture distinct, sutural edge continuing as a keel to the reflected
margin of the aperture; aperture very short necked, almost circular
broadly reflected ; the pillar, as usualin the genus, tubular above the
last whorl, the axis externally simple but somewhat flexuous. Lon.
22°5,max. diam. 6°5 mm. El Paso County, Texas, from Mule cafion at
an elevation of 4000 feet. This species is nearest to H. coahuilensis
W.G. Binney, which has one or two more whorls, the last two propor-
tionately more attenuated with more extended, sharper and more dis-
tant sculpture, and obtusely keeled or compressed base resulting in
a much more triangular and narrower aperture. _It is not particu-
larly close to any of the other species hitherto described, the H. semi-
striata Stearns being quite distinct. A marked character is the
evenly rounded basal part of the whorl just behind the lip.
The specimens were procured by a correspondent of Mr. J. A.
Singley.
MEGATEBENNUS BIMACULATUS.
BY MRS. M. F. BRADSHAW.
One day last September I found a curious and interesting mollusk.
On a ledge of rocks, so high as only to be reached by the waves at
the highest tides, there was a hollow containing a barrel or more of
water.
Poking around in this I saw what appeared to be a bit of flesh.
I took it out, thinking I had found a small Lucapina crenulata,
THE NAUTILUS. 113
whose shell is—or appears to be—internal. But this one wore his
shell upon his back for what purpose I do not know, for it was too
small for protection, and the creature himself was so unpleasant to
look at, no beauty of shell could redeem his ugliness.
Red-brown in color, warty, even the inadequate shell was a dull
greenish-grey ; not a single pretty feature !
Only an enthusiast could have taken him up with a thrill of
pleasure, instead of a qualm of disgust.
Upon examination at home, it was determined to be Fissurellidwa
bimaculata ; yet the shell does not quite tally with the description in
West Coast Shells. Internally it is white, outside gray-green with
fine sculpturing; the rays running from the aperture to the edge
are strong, the circular ribs faint, and the margin is not crenulated.
F’. bimaculata is said to be ¢ in. in length ; this one is more than double
that size. And the dark spots on the sides are not visible. If the
green stain could be removed perhaps they would appear; but as
the size is too great for bimaculata, perhaps I have a Fissurella not
credited to this coast.
ON COLLECTING PISIDIA.
BY DR. Y. STERKI.
Pisidia, and for a good part Sphaeria, are by far not sufficiently
known, systematically as well as geographically. Requested to do
so, and encouraged by prominent conchologists, the writer is going
to work them up. Already some valuable materials are at hand ;
thus the entire Pisidium-collection of Mr. E. W. Roper, numerous
lots, most from Lake Michigan, sent by Mr. Bryant Walker, others
from Mr. H. Prime.and other conchologists, besides my own col-
lection ; and some good results have so far been attained. Yet these
materials are absolutely insufficient for athorough study and knowl
edge of these small mussels which, with all their minute size, are a
very conspicuous and interesting part of our molluscan fauna. They
should be studied in their different forms, considerably variable
according to their habitats, and all kinds of waters should be searched
for them all over the continent.
Whoever has collected Corbiculidae assiduously will know that
they are, as a rule, present in large numbers, wherever found. The
144 THE NAUTILUS.
best means for collecting them isa rather long (8-12 inches) net of
strong canvas, such as used for embroidery work, fastened to a ring
of strong wire’, five to eight inches diameter, with a handle, to be
used either directly, or fastened to a stick, or pole up to ten or
twelve feet long. For deep waters a dredge should be used. ‘The
“stuff” gathered is shaken and washed until the remains are free of
fine mud, then in a basket, sack, or some other suitable receptacle
brought home, where the mollusks, Corbiculidae and others, may be
picked out at leisure. If they are not to be kept alive, it is best to
spread the materials on large pieces of paper, or cloth (bed sheet e.
g.) and let them become dry. In this way, especially if one or
several fine sieves are used, they are most easily found; and none of
them should be overlooked, as some forms are very minute, and the
young of all are of interest, while fully grown specimens are compar-
atively scarce, and so are certain species in some places. If sent
for examination, all from a locality are best left mixed up, and not
separated, but with notes on the nature of their habitat.
Hundreds, and thousands of specimens may be secured in a short
time, not to speak of other mollusks, among which, last not least,
very young Unionide. The best places are, as a rule, among
aquatic plants, and also in deep places, or holes, where the mussels
are washed together. But it must also be said, that they are found
most actively propagating in late fall and early winter.

Shell small, whitish corneous, solid, lens-shaped ; intermediate in
form between P. exacutus and P. dilatatus. Upper surface convex,

‘but the apex is slightly sunken ; whorls nearly three, slightly con-
vex, rapidly widening, acutely keeled at the periphery, the keel
projecting above the suture on the penultimate whorl in most adult
specimens. On the last whorl the keel is about median in position,
is acute, as if pinched out, and extends to the aperture. Base of
shell convex, rising toward the umbilicus, which is moderately large
and funnel-shaped, with very obtusely angled margin. Aperture
small, oblique, sub-rhombic ; the lip strongly thickened within. Alt.

Woodville, Alabama (Prof. H. E. Sargent). This is a smaller
species than P. exacutus, with much smaller less oblique aperture,
thick lip, and not so flattened. It differs from P. dilatatus in the
acute peripheral keel, etc.
Amnicola olivacea n. sp.
Shell olive-colored, somewhat intermediate in form between an
ordinary Amnicola and Pomatiopsis lapidaria. Spire elevated, the
apex rather acute. Whorls 5, very convex. Aperture ovate, less
than half the length of the shell, angular above; peristome free ex-
cept for a very short distance on the parietal wall; umbilicus
rather large. Surface smooth; coated with iron oxide in the adult
Specimens seen.

Alt. 4:2, diam. 3 mm. (Female ?).
Huntsville, Ala. (coll. by Prof. H. E.Sargent; see NautiLus for
December, 1894, p. 95).
This form is quite distinct from other Amnicola, being of more
elongated contour than any other Northern forms except A. lustri-
ca. Its nearest allies aresome of the smaller slender Floridian forms,
but none of these have such convex whorls. As I have seen dry
specimens only, I have not verified the reference of the stouter in-
dividuals to the female sex, but from analogy with other species this
is probable. The supposed males have much the general appear-
ance of Pomatiopsis cincinnatiensis.
-Planorbis bicarinatus aroostookensis n. var.
Shell having the spire and umbilicus very deep, the latter funnel”
‘shaped as in typical bicarinatus, but both upper and lower keels en-
tirely obsolete or rounded off on last whorl, which has the aspect of
that of P. trivolvis. Surface minutely striated spirally as in P. bi-
carinatus. Aperture less angular and less produced below than in
Sicarinatus, in consequence of the rounding of the whorls. Diam.

NOTE ON UNIO OREGONENSES LEA.
wiry i < 2.5 OY)
or years | have been puzzled over a shell in the Lea collection:
of Naiads which Lea received from Wheatley as coming from the
THE NAUTILUS. 117
Columbia river, Oregon and which the former named U. oregon-
ensis, discribing and figuring it in Trans. Am. Phil. Soc. X, p. 275,
pl. 22, fig. 33. The specimen is in bad condition, being somewhat
broken and considerably eroded. In a paper on the Relationships
and Distribution of the North American Unionide, with notes on
the West Coast Species, which I published in American Naturalist,
Vol. XX VII, No. 316, I stated that I had come to the conclusion
that the specimen in question was a form of the widespread and
variable Unio luteolus Lam, there being examples in the National
Museum from Canada very much likeit. I believed that if it really
came from the Columbia river it was just possible the young might
have been carried in mud on the feet of aquatic birds, from waters
near by which drain into the Missouri, in which stream U. luteolus
isfound. But I have never been quite satisfied with my determina-
tion of the shell, since it always seemed to resemble to some extent
a group of the Mexican species. To-day, in carefully going over
all the Mexican and Central American Naiad material in our own
and the Lea collections I suddenly discovered a surprising resem-
blance between the Lea specimen and some others of U. rowelli Lea,
and on careful comparison I found it to be undoubtedly an old, solid,
and inflated female of that species.
Unio rowelli is a remarkably variable form which I cannot for a
moment doubt is exactly synonymous with U. maeneilii Lea, the
types of both species being in the Lea collection. Lea calls atten-
tion in his description to its resemblance to U. sapotalensis, to which
it is closely related, and it may be remarked in passing that in this
group the females and males are separate, the former being inflated
in the posterior ventral region like those in the Luteolus Group.
Some specimens of this protean species are much inflated, others are
compressed ; some are somewhat triangular and pointed at the base
of the posterior slope, without a trace of biangulation, others are
nearly rhomboid and distinctly biangulate; there is considerable
variation in the degree of sulcation, and in the coloring of the epi-
dermis. They may be either uniform greenish-yellow, brownish,
or marked with distinct and delicate radiating stripes asin the type
of U. oregonensis. And all these variations may occur in a lot from
a single locality.
The cardinals are rather compressed, double in the left and single
in the right valve, and have a peculiarly rough, torn appearance ;
while the laterals are somewhat striated longitudinally.
118 THE NAUTILUS.
As Unio oregonensis was described probably about the year 1852,
rowelli in 1859, and Macneil in 1874, the former should have pre-
cedence. But it may be set down as an absolute certainty that no
member of the group to which this species belongs was ever found
nearer than 1500 miles from the Columbia river, and the locality is
undoubtedly an error. As the name oregonensis is, therefore, mis-
leading, I think we are justified in applying to the species the next
oldest name, Unio rowelli of Lea. As I have shown in the article
referred to in American Naturalist that Unio famelicus Gld. of the
Columbia region is only a young: Unio multistriatus Lea, of Brazil,
I think I am safe in saying that no Unios are known to inhabit
North America west of the great Rocky Mountain chain; this
being the largest area distitute of Unio life in the temperate or
tropical regions of the globe.

A Train Sroprpep By Snaits.—Mr. Laille, an engineer in the
employ of the Tunisian Railway, writes in the Dipeche Tunisienne :
“The train coming east from Suk-el-Arba last Thursday was two
hours late for a very singular reason. ‘The road was literally cov-
ered with snails, the wheels of the locomotive crushing these mol-
lusks into a pulp, which destroyed all adherence and caused the lo-
comotive wheels to skate, so to speak, in their places. We have
seen flocks of locusts stop trains, but I think the fact that snails
can stop a train is without a precedent. These snails are very gen-
eral all through Tunis, especially during the rainy season; the
smallest remainders of green on field or tree are covered with them,
so much so that they appear like a bunch of grapes hung up, only
that their white shells produce a curious effect.”— Phila. Record.

NEW PUBLICATIONS.
THe Lire anp Wrirtincs or Rarinesque, By Richard Ells-
worth Call.’ (Filson Club Publications, No. 10).—To most natu-
nralists, a peculiar charm attaches to the personalities of their
predecessors in the same field of endeavor. And we of to-day, who
may fairly be reckoned as the third generation of nature students
in America, have a natural curiosity to know something of the men
of that first generation, to whom the “ New World” was indeed
new—who enjoyed in such generous measure that intense delight
which can only be felt or apppreciated by the field naturalist in the
presence of forms of life new to him. Rafinesque, the subject of
Mr. Call’s present work, has been much less familiarly known to us
than any of the other pioneers in American zoology; he was mis-
understood by most when living, and scoffed at dead. It is, there-
fore, with unusual interest that we follow the tale of his eventful
life as it is here related. Mr. Call, after telling of his early train-
ing, or rather lack of training, follows his hero to France and then
to Sicily, where Rafinesque’s life work was begun, and his peculiar
characteristics as a naturalist were developed. When he finally
left that sunny island for America, he was already the author of
many works and papers on numerous branches of zoology and _bot-
any, though only thirty-two years of age. His career of misfortune
in-America—relieved only by the intense pleasure of his work—is
graphically described, the period covered by his life in Kentucky
being given most space, this time covering Rafinesque’s most im-
portant contributions to American science. ‘Two portraits of
Rafinesque are reproduced, as well as an autograph letter and sam-
ple pages of some of his works, all by good photo process engray-
ings. The volume concludes with a bibliography, which seems to
be complete.
The character of Rafinesque is appreciatively interpreted by Mr.
Call, and his shortcomings are as leniently mentioned as strict re-
‘1 Louisville, Kentucky, 1895, 4to. pp. xii, 227.
120 THE NAUTILUS.
gard for right will admit. Acknowledging frankly the great de-
fects of the eccentric naturalist’s work, its value and genius are
still considered by Call to be very considerable. There can be no
doubt that in the appreciation of natural groups, Rafinesque had
great insight, as his biographer claims; but still we can hardly en-
dorse the statement: “considered as a whole, the conchologic work
of Rafinesque was remarkably well done.” From some acquaint-
ance with that work, we would rather call it remarkably badly
done, and only saved from worthlessness by certain glimmers of
genius, in the ability to grasp natural groups. Some facts of value
could have been obtained had Mr. Call corresponded more freely
with Philadelphians, as here Rafinesque spent many years. Among
other things, the statement in regard to the Poulson collection of
Rafinesque’s Unionide on p. 109, would not have been made. This
collection was collected and labelled by Rafinesque, was procured
by Tryon from Poulson’s estate and is now preserved in the collec-
tion of the Academy of Natural Sciences of Philadelphia.
As a whole the volume seems remarkably free from mistakes of
any kind, considering the difficulty of the subject. The typography
is superb. ‘The proof-reading is almost perfect, though we note a
very few slips, such as “ profligate” for prodigal, on p. 75. It is
printed on fine paper, with wide margins, and is altogether a beau-
tiful piece of book-making. We trust it will find a place on the
shelves of conchologists and naturalists generally, and lead toa
more just appreciation of this great though erratic genius.
THE MrecuanicaL Cause orf Foups IN THE APERTURE OF THE
SHELL or Gasrropopa, By Wm. H. Dall (Amer. Nat., Nov.,
1894).-—The plice and folds found in the aperture and throat of
gastropod shells are explained by the wrinkling of the mantle when
retracted into the gradually narrowing caliber of the shell, and
pressed between the solid foot and the shell wall. The semi-fluid
secretion of which the shell-lining is built up is exuded from the
whole surface of the mantle, but becomes rubbed off where the sum-
mits of mantle-folds press against the shell, gradually accumulating
in the interstices between these folds. It is found that in shells
having the ridges extending far inward, the adductor muscle is at-
tached far within; in those having no folds, or only at the margin
of the aperture, the adductor is attached to columella lower down.
The deeper this attachment, the greater the distance over which
the mantle is drawn, and consequently the greater its folding by
compression, and the more emphatic the shell-ridges deposited by it,

UNIO OCHRACEUS AND CARIOSUS.
BY CHARLES TORREY SIMPSON.
The senior editor of the Nauriius has asked me to point out in
a clear concise way the specific differences between Unio ochraceus
Say, and] Unio cariosus Say. ‘They were both described in Nichol-
son’s Encyclopedia, in an article on conchology, by Say; and the
work, which is now long out of print, is exceedingly rare, and out
of the reach of the ordinary student.
Union ochraeeus Say.
Both belong to a great assembly of North American forms fairly
typified by the well known Unio oceidens, it being one of the few
groups that are well represented both in the Mississippi Valley and

132 THE NAUTILUS.
Atlantic drainage areas, which in the main are peopled by very dif-
ferent Unio faunas.
The species which are the subject of this note, though closely re-
lated and having about the same geographical distribution, are no
doubt distinct, and when one has learned to separate them he rarely
has any difficulty in distinguishing them at sight. As arule, Unio
ochraceus is the more inflated and thinner shell of the two; it is al-
most invariably dull-colored, and the epidermis, especially at the
posterior end is generally raised into slight irregular folds, which
follow the growth lines. The rays, which are dirty green and ill-
defined, usually cover the posterior part of the shell, and sometimes
extend over the whole disc, becoming fainter towards the anterior

end. The interior is dull-colored, often lurid, and quite frequently
tinted with reddish salmon or purple.
On the other hand, Unio cariosus is generally the more com-
pressed of the two ; often showing a fairly well-defined angle on the
posterior slope; it is almost-invariably smooth and shining; the
epidermis being yellowish or a dirty straw color, sometimes tinted
with brown. Usually above the posterior slope there are a few
wavy, very distinct, dark green rays, and sometimes, though rarely,
this radiation extends over the shell. The interior is usually white
or silvery, and more or less iridescent posteriorly.
In a very large series any of these characters may fail. Speci-
mens of U. cariosus may be inflated, or very rarely slightly rough-
ened; there may be individuals of either species that are uniform
in color, or rayed throughout, but in an extensive set they will, for

the most part, hold good; and the roughened, dull exterior, feeble
rays, and lurid interior of U. ochraceus, and the shining epidermis
and well defined posterior rays of U. cariosus are very constant.
Unio cariosus, on the whole, approaches much closer to forms of U.
occidens than it does to U. ochraceus.
The latter ranges from the Connecticut River and the state of
New York, south in the waters of the Atlantic drainage to Savannah,
Ga. Two specimens from the latter locality have remarkably red
interiors, and are a little peculiar, but are undoubtedly the species
in question. Unio cariosus is found in the vicinity of Quebec,
Canada, according to Latchford, and it has been reported from west-
ern New York. A doubtful specimen is in the Lea collection from
Talledega, Ala. It is in the same collection from Edgefield, S. C.,
Ogeechee River, Ga., and Columbus, Ga., and these are no doubt
correctly named. Other shells in the Lea collection from Nas-
hotech, Wis., and Ontonagon, Mich., are very probably forms of
Unio occidens.
NOTES ON THE REPORTED EXTINCTION OF THE GENUS ACHATINELLA
AND MARVELOUS DEVELOPMENT OF A FLORIDA FASCIOLARIA.
BY JOHN FORD.
A most extraordinary account of a collection of shells, located
somewhere in the interior of New York State, was handed me mee a
friend a few days ago.
This purports to have been written by a correspondent of a
Rochester newspaper, in the columns of which the article probably
first saw thelight. The writer, it appears, does not claim any scien-
tific knowledge of shells, nor can it positively be said that his bump of
imagination is abnormally developed. Nevertheless, he has given to
the paper alluded to, and consequently to the world, some very re-
markable bits of information. Information, indeed, which, if true, |
shows how puny are the geographical and scientific acquirements of
the general run of conchological students. Of course, for lack of
space in your columns, reference can only be made to one or two of
the marvelous statements embraced in the article. One of these re-
fers to the genus Achatinella, of which the writer says, “ This shell
is confined to the Sandwich Islands and its tenant feeds on the
124 THE NAUTILUS.
herbage of these islands. Since the islands have been pastured, the
‘variety’ has almost entirely disappeared, and probably not more
than a half dozen specimens could be found there to-day.” What
a dire calamity! and how remarkable that these pretty little crea-
tures should have “ shuffled off their mortal coils” in the very sea-
son that less regal robes slipped trom the shoulders of their Island
Queen.
A few flippant students may question this tale of starvation in the
midst of green pastures, but it will perhaps be well for them to
pickle their opinions, since the positive assertions of “ correspond-
ents” are not to be trifled with. The shell expert who can doubt
this starvation story would quite as likely question the following
narrative said to have been written by the “ experienced collector ”
who forwarded the shell referred to, to the aforesaid unparalleled
New York aggregation, viz.; “ The large Florida Fasciolaria father
found one day by accident.
“While drifting about in Florida waters his boat suddenly
touched what seemed to be a rock but it proved to be an immense
specimen of the Fasciolaria (sic), alive and travelling.” “This speci-
men weighs several hundred pounds.”
A brief statement to be sure, but a graphic one, as the reader
will admit. There is not a word, however, as to whether the boat
was wrecked in its “ sudden ” contact with the limy mass “ weighing
several hundred pounds.”
Nor is there any reference to the final disposition of that part of
“the Fasciolaria ” which, when struck, was “ alive and travelling.”
But this fact matters little, perhaps, since we are assured that the
“several hundred pounds” were gotten safely to the shore, and
finally into that collection of shells which (I quote again) “ is ex-
pected to be in a short time the most complete and valuable une,
from a scientific standpoint, in the world.”
Presumably this monster of “ Florida Waters” is known to
Science as Fasciolaria gigantea, but alas! how pitiable has been the
ignorance of the scores of so-called conchological experts who have
hitherto believed that this, the largest species of the genus, did not
exceed a paltry ten pounds in weight. Think of it, ye academic
plodders who for years have been gazing with wonder upon a petty
eight pounder, imagining the while that Florida had utterly failed to
produce anything larger in the same line. O, the pity of it! You
that have given years of study and thought to the molluscan world,
THE NAUTILUS. 125
how could you so mistake a pigmy for a giant, a veritable baby for
a grandfather? Far better would it have been had you made a
Mecca of the Empire State and sat at the feet of its astute corre-
spondent, whose present throne is, doubtless, ye same old Fascio-
laria, “alive and travelling” and “weighing several hundred
pounds.”
NOTE ON HELIX SAULIZ PFR (non REEVE)—PALUMBA SOUVERBIE.
BY HUGH FULTON, LONDON.
Owing to an error in Reeve’s Monograph some confusion has
been caused as to the identity of the above species; both Pilsbry
and Hidalgo have taken Reeve’s description and figure (Conch.
Icon., fig. 393) as being that of the type of sauliew, consequently,
and with reason, they have considered the palumba of Souverbie to
be distinct from the former species. The fact is, that when Reeve
described and figured his saulie, he had not the type of that species
before him; the type specimen of Pfeiffer’s saulie in the Cumingian
collection, is identical with the palumba of Souverbie, Journ. de
Conchyl., 1858, p. 369 ; 1862, t. 10, f. 5.
I have not been able to find in the Cumingian collection the
shell figured by Reeve.

NEW SPECIES OF LAND-SHELLS FROM THE GALAPAGOS ISLANDS.
BY WILLIAM H. DALL.
Bulimulus (Nesiotus) Reibischii n. s.
Shell elevated, slender, of a pale ferruginous tint, rather solid,
with nine whorls; apex funiculate as in other Nesiotes, the first
two (nepionic) whorls finely ribbed and polished, the remainder
with numerous oblique or irregular transverse ribs crossed by nu-
THE NAUTILUS. 127
merous sharp spiral threads, with wider interspaces ; suture distinct,
somewhat appressed; base of last whorl somewhat attenuated ;
whorls little inflated, but not flattened; umbilicus a mere chink ;
aperture oval, higher than wide, rounded in front, the pillar simple,
the margins thickened but not reflected. Lon. 11:0; max. diam.
2°5 mm.
This shell has the sculpture of B. rugiferus Sby., and somewhat
the form of B. chemnitzioides Fbs., though shorter and with fewer
whorls. It is fairly intermediate between Nesiotus and Plewropyr-
gus. Two specimens were collected by the U.S.S. Albatross at
Indefatigable Island. The species is named in honor of Herr Paul
Reibisch who has recently worked up the Wolf collection from
these islands.
Bulimulus (Nesiotus) Fanneri n.s.
Shell short, stout, pointed, with six whorls of which two are nepi-
onic with the usual sculpture, while the others are marked only by
lines of growth and microscopic, inconstant spiral striation, of
which the most prominent lines are regularly spaced and micro-
scopically beaded, when present; color pinkish or slightly brownish
white, no peripheral pale band visible on the specimens which, how-
ever, are not perfectly fresh ; whorls well rounded, umbilicus large
and deeply pervious; aperture large, with a widely reflected lip,
the outer lip much bent over on the body, closely approaching the
pillar and united to it by a distinct callus. Lon. 11:0; max. diam.
70 mm.
This belongs to the B. jacobi group, and is about the size of small
varieties of jacobi, but is more conical and stouter, and has an aper-
ture very differently shaped and with a more broadly reflected lip
than any other species from these islands. It was found with the
preceding and is named in honor of Capt. L. L. Fanner, com-
mander of the Albatross. The pillar is perfectly plain and with no
sulcus or fold at the base.
NOTE ON TASMANIAN ACMEA AND ISCHNOCHITON.
BY H. A. PILSBRY.
Acmea cantharus Reeve.
The habitat of this species was said, by Reeve, to be New Zealand ;
but Prof. Hutton, some years ago, corrected this error, stating that
128 THE NAUTILUS.
it is Tasmanian. Numerous specimens received from Mr. H.
Suter, collected by Mr. W. L. May, at Frederick Henry Bay, Tas-
mania, show a considerable range in pattern of coloring. The in-
terior is very much like that of Lottia gigantea, and the anterior,
marginal position of the apex also forcibly recalls that West Ameri-
can species.
Acmea parva Angas, var. tasmanica n. v.
Shell smaller, wider and higher than “ Nacella” parva Ang. (P. Z.
S., 1878, pl. 54, f. 12), opaque white, with radial irregular rays of
bluish or subtranslucent white at the sides and short, transverse bars
of the same on the back. Length 8, breadth 2:2, alt. 1:5 mm.
Estuary of Derwent R., Tasmania, 10 fms. Collected by Mr. W. L.
May.
Ischnochiton (Haploplax) Mayi n. sp.
Shell short-oval, moderately elevated, carinated, the side-slopes
slightly convex. Surface smooth to the naked eye, but finely gran-
ular. Color of valves and girdle uniform black above, or slightly
brownish at the beaks when eroded.
The intermediate valves have almost straight sutures, even a trifle
concave in old specimens, the beaks projecting a trifle in young
ones. Lateral areas distinctly raised (the diagonal distinct and rather
wide), sculptured with several arcuate, indistinct growth-marks,
sometimes showing very slight traces of coarse, low pustules, but
these are hardly mentionable; all over minutely granulose in dia-
mond pattern. Central areas with faint growth-strie anteriorly,
distinctly granulose at the sides, the granules arranged to form for-
ward-converging riblets, which, though slight, are apparent on the
outer half of each valve; central portion of central areas smoothish,
with faint granulation only, beaks smooth. End valves sculptured
like lateral areas. Valve viii with mucro projecting, at about the
anterior third ; the posterior slope concave below the mucro and
then straight.
Interior dull blue-green, greener behind the rather heavy valve-
callus, the depth of the cavity rather lead-color. Sutural laminze
small, projecting less than half the length of a valve; sinus wide.
Slits in valve i, 11; valves ii to vii, 1-1; valve viii, 12-13. Teeth
sharp, smooth and short.
Girdle black, clothed with densely imbricating, coarse, convex,
smooth scales,
THE NAUTILUS. 129
Length 8, breadth 6 mm.; larger, “curled” examples would
measure at least 10 mm. long. Divergence the same as in J. smar-
agdinus.
Eagle Hawk Neck, east coast of Tasmania. Collected by Mr. W.
L. May, and communicated to me by Henry Suter.
This species belongs to the group of smoothish Australian species,
such as lentiginosus Sowb., smaragdinus Angas and virgatus Reeve.
It has more distinctly differentiated lateral areas and better de-
veloped pleural sculpture than any of them, and is, moreover, of a
uniform black color. Types in coll. Acad. Nat. Sci., Phila.
In this connection it may not be out of place to direct attention
to certain errors in the volume on Chitons in the Manual of Conch-
ology. By the study of many specimens received from Messrs Brep-
NALL and Cox, I find that two species were “lumped” under the
name Ischnochiton contractus. (1) I. decussatus Reeve, of which
castus Rve. and speciosus Ad. and Ang. are synonyms, and (2) con-
tractus Reeve, of which Mr. Sykes considers pallidus Reeve a syno-
nym. On account of the inadequate illustration and description of
Reeve’s C. crispus, I did not recognize it in my Isch. haddoni; but
upon sending specimens of the latter to Mr. E. R. Sykes for com-
parison with Reeve’s type, he informs me that they are the same.
While something might be said in favor of ignoring Reeve’s name
on the score of insufficient definition, it may, in the long run, be
better to receive it and make my own J. haddoni a synonym of J.
erispus. I regret the change, because my intention was to honor
Prof. Happon, whose work on Chitons, as well as in other depart-
ments of Zoology, is of great merit; and a synonym is rather a
doubtful honor. |
NEW SPECIES OF LAND SHELLS FROM PUGET SOUND.
BY WM. H. DALL.
In some minute shells sent for examination by Mr. P. B. Ran-
dolph, of Seattle, after eliminating species already known, two forms
appeared to be inedited. Having sent them to Mr. Pilsbry for
criticism, he agrees that they are new, and the following descrip-
tions are submitted.
130 _ THE NAUTILUS.
Patulastra? (Punctum ?) pugetensis n. s.
Shell minute, pale greenish yellow, nearly smooth, the first whorl
and a half smooth, the others with fine, silky, close-set, hardly ele-
vated lines or minute regular riblets, somewhat flexuous and in
harmony with the incremental lines; form moderately elevated, the
whorls inflated with a deep suture, and, in the adult, rapidly en-
larging near the aperture in the latter part of the last whorl; aper-
ture large, quite oblique, almost circular, the segment of the body
between the two lips about one-sixth of the whole; umbilicus ample,
scalar, exhibiting part of all the whorls which make, in adults, from
three to three and a quarter volutions,
Alt. 0°5; max. diam. 1:5, min. diam. 1'°2 mm. Habitat, Seattle,
Wash., under leaves.
Pyramidula? Randolphii n. s.
Shell minute, reddish brown, with dull silky lustre, elevated, with
three and a half rather inflated whorls; sculpture only of fine incre-
mental lines, barely perceptible under an ordinary triplet lens; su-
ture deep, periphery rounded, slightly less so in the immature shell
but seemingly never angular ; aperture obovate, somewhat oblique,
wider than high, the body segment about one third of the whole;
top dome-like, base full, umbilicus small, subcylindric, deep.
Alt. 0°75, max. diam. 1:4, min. diam. 1:25 mm. Habitat, with
the last.
This little shell recalls Conulus fulvus in form, but wants the
polish and imperforate base, and is more elevated and inflated than
C. fulvus of the same number of whorls. It is not unlike the little
Helix granum Strebel on a smaller scale. It is named in honor of
the gentleman who collected it, who is deeply interested in the mol-
lusk fauna of the Sound region.
NOTES AND NEWS.
PorrRAIT OF RAFINESQUE.—We are informed that portraits,
suitable for framing (12 x 14 inches), may be had for a nominal sum
to cover postage and packing, by addressing Prof. R. Ellsworth Call,
Manual Training High School, Lowisville, Ky.
By error, the name of the author was omitted from the paper
“Note on Unio oregonensis Lea,” in the last number of the Nautt-
Lus. It should have been signed Charles T. Simpson.
THE NAUTILUS. 131
Navarcuus.—In working upon the Tectibranchs for Vol. XVI
of the Manual of Conchology, I find that the name Navarchus, ap-
plied to a group of Doridiide, is preoccupied. I propose, therefore,
to substitute Navanaz, the type being NV. inermis Cooper.
PLEUROTOMARIA Bryricui.—A specimen of this rare species
has lately been added to the National Museum Collection, which
now possesses three of the four recent forms of the genus.
Nore on PoraMAnax.—The name given to this group of tropical
American Melanians has been used again for a genus of Lepidoptera
(Watson, Hesperide, P. Z.S., 1893, p. 55). As thesignature of the
Proc. Acad. Nat. Sci. Phila. containing the description of the mol-
lusk genus was actually distributed on Jan. 24, 1893, and the paper
containing the Lepidopterous genus was printed under the proceed-
ings for Jan. 17, 1893, the latter has apparent priority. However,
the proceedings of that meeting could hardly have been actually
printed until some weeks after the meeting, so that it is extremely
probable that the name of the Lepidopter is later in date of actual
publication, and must, therefore, be changed.
We are indebted to Dr. W. D. Hartman of West Chester, Pa.
for the illustrations of Unio ochraceus and U. cariousus in this
number. They are from his Conchologia Cestrica, an excellent
work describing and figuring the shells of Chester Co., Pa., and
incidentally the majority of those of the Middle States.
Anatomy oF Hemicycira.—Dr. A. Krause (Nachbl. D. M.
Ges. Jan.-Feb. 1895, pl. 1) has recently dissected several species of
this Canary Island group of Helices, and finds their anatomy to be
practically identical with that of Tachea. The rank and position
assigned the group in Pilsbry’s “Guide to the Study of Helices” is
therefore fully confirmed. Its relationships are not with the
Madeira and Azores Helices of the genus Leptaxis, but with the
forms of true Helix of the European and N. African mainland.
NEW PUBLICATIONS.
THE ZooLoGcicaL Recorp for 1893 has appeared, containing the
records of Mollusca, Brachiopoda and Bryozoa, by Mr. B. B. Wood-
ward. These digests of the literature of zoology are of such great

the Zoological Society upon the admirable manner in which the
present Recorder has performed his difficult task. Mr. Woodward
should have the hearty codperation of all the conchologists. His

CRUISE OF THE STEAM Yacut “ WILD Duck” IN THE BAHAMAS,
etc., NorES ON THE SHELLS CoLLECTED, by Wm. H. Dall. (Bull.
Mus. Comp. Zool. xxv, No. 9.) It appears that the lagoons of the
Bahama Is. are peopled by a peculiar mollusk fauna, evidently
derived from species living normally in the sea outside. The
number of lagoon species is small, and they are all marked by (1)
thinness of shell; (2) diminutive size; and (3) when colored at all,
by brilliancy of color, as compared with their nearest relatives in
the adjacent sea. Among others enumerated by Dall which are
common to the sea and the lagoons, are the following which occur
only in and are characteristic of the latter: Cyrena colorata Prime,
Venus (Anomalocardia) leplalea Dall, Tornatina parviplica Dall,
Cerithium (Pyrazus) 7-striatum var degeneratum Dall, Cerithium
tenuis Pfr. |
A considerable list of land species is given, among them Chondro-
poma watlingense and Cerion Agassizt are new, the latter fossil.
Dall calls attention to the fact that the name Strophia is preoccupied,
and proposes to substitute Cerion Bolten, 1799, as Morch had
already done in 1850. He gives names to the subdivisions of the
genus indicated by Maynard, as follows:
CERION s.s. Parietal lamina short, situated in the angle between
pillar and body-whorl; short internal sets of laminz persistent ;

MOLLUSK FAUNA OF PHILADELPHIA AND ENVIRONS.
BY MORRIS SCHICK.
In the Proceedings of the Academy of Natural Sciences of Phila-
delphia for 1861, page 306, Mr. W. M. Gabb has given a list of
Philadelphia mollusks, enumerating 62 species, seven of which are,
however, synonyms or doubtful inhabitants of this region. Having
collected a number of species in this vicinity which are not on Gabb’s
list, the writer thought it well to make a new one, giving exact locali-
ties where the various species have been found during the last two
or three years in the neighborhood of Philadelphia, and including
not only those forms personally collected, but also the species and
localities discovered by other local naturalists—Messrs. Walton,
Vanatta, Stone, Pilsbry, McGinty, Johnson, Ford, Fox and Eisen-
hardt, all of whom have contributed materially to the list.
The importance of the Philadelphia fauna, as being the type lo-
cality of many of Thomas Say’s species, will always render it
of interest to those who study geographic variation ; and moreover,
an accurate local list is of value to conchologists in the future, in
determining the ever fluctuating geographic limits of species and
varieties. While many of the special localities herein recorded
will be destroyed by the growth of the city, others situated in Fair-
mount Park, especially along the Wissahickon, will doubtless per-
petuate within the city limits most of the species indefinitely ; and
the aquatic forms will survive at least as long as the Schuylkill
furnishes the water supply of the city.
134 THE NAUTILUS.
The west bank of the Schuylkill above Girard Avenue was a
very good collecting ground, where one could find in good numbers
Polygyra hirsuta, P. thyroides, P. tridentata juxtidens, Pyramidula
alternata, Gastrodonta ligera, G. suppressa, G. nitida, Vitrea ar-
borea, and Selenites concava, with a few others not so common; but
this place has been destroyed this year by the laying out of a drive.
On the land shells of the park, see Ford, Conchologists’ Exchange,
TE pt:
In his list Mr. Gabb refers to Helix labyrinthica as common near
Germautown ; I have been able to find but three specimens of this
species, after a dilligent search of three seasons. He also mentions
H. hirsuta as one of our commonest species, but this is now also un-
common; while others are becoming rare, there are some species
now quite common that are not mentioned in Mr. Gabb’s list, such
as Limax maximus, Pyramidula striatella, Vallonia costata, Pupa
contracta, Succinea obliqua, Spherium striatinum, S. transversum, ete.
Helix egena Say, a depressed form of Conulus fulvus, was described
from ten miles above Philadelphia; and C. chersina=fulvus is re-
ported in Gabb’s list as found near Germantown by Tryon. It has
not occurred to recent collectors.
Helix appressa, admitted by Gabb, on the evidence of one speci-
men found on E. K. Tryon’s estate near Germantown, was evidently a
lost cabinet specimen. Am~nicola lustrica Say of Gabb’s list is the
half grown Pomatiopsis lapidaria. “ Margaritana rugosa Say,” is
an evident pen error for M. marginata Say, which Gabb omits.
Unio fisherianus reported from the Schuylkill above Girard Avenue

NOTE ON THE SPECIES OF VERONICELLA FOUND IN CENTRAL AMERICA.
BY T. D. A. COCKERELL, N. M. AGR. EXP. STA.
It must be confessed that our knowledge of the Central American
forms of Veronicella is singularly inadequate, and the purpose of
this note is mainly to draw attention to the matter, in the hope
that those who have the opportunity will add to our information.
THE NAUTILUS. 141
It may be as well to say at once, that for satisfactory work in
this genus it is desirable to have at least a dozen mature examples
of each species. Working with few examples, there is danger of
taking varietal characters for specific ones, if the species is little
known. Once the true specific characters have been ascertained
from a good series, any single example, if mature, can be deter-
mined ; but it is quite otherwise when the form is new, or belongs to
a species which has been described from only one or two examples.
From necessity, species in this genus have, in the past, usually
been described from one or two specimens. The descriptions, if pre-
pared with reasonable care, even without anatomical details, will, I
believe, be easily recognizable hereafter. But at present we do not
know, in very many cases, which of the characters mentioned in the
descriptions are really specific, and consequently whether the as-
sumed species are valid.
I do not wish to suggest that species of Perintiolla ought not to
be described without numerous examples. If naturalists were to
wait in every case until the material was as abundant as they could
desire, our knowledge of tropical species of many groups would
hardly advance atall. When astudent introduces a presumed new
species of Veronicella, having carefuily ascertained that it differs
from all previously described forms, and in his description sets forth
that difference, he undoubtedly does good service. We are not to
be prevented from interesting ourselves in the forms of Veronicella
because we do not always know whether we are dealing with spe-
cies, races, or varieties. But we should like to know the real status
of each form, and must consequently urge those who have the
chance to collect material to do their best to obtain sufficient.
The first Central American Veronicella to be named was J. olt-
vacea Stearns, 1871. It was found in Nicaragua and has been
supposed to inhabit California also. Although it is practically cer-
tain that it is not a native of California, it has been described in
works on North American mollusea on the supposition that it be-
longed to that fauna. I have seen a specimen from Nicaragua, and
have given a few descriptive notes in Ann. Mag. Nat. Hist., Nov.,
1890, p. 389. Mr. W. G. Binney has published a figure of this
same specimen.
The next species was made known in the year following, 1872.
This was V. moreleti Crosse and Fischer, from Mexico; fulvous
with two blackish bands, whereas olivacea has no dark bands.
142 THE NAUTILUS.
In 1875 a second Mexican species was announced, V. mexicana
Pfeffer, in Strebel’s work on the fauna of Mexico, p.130. It was
47 mm. long, red-brown to grey-brown and black-brown.
For many years no more additions were made; until in 1885 (or
Jan. 1886?) Dr. Semper’s elaborate work on the genus appeared.
In this, on p. 293, we find V. mexicanus n. sp., from Mexico; but
the author having discovered, too late to change the text, that there
was already a species of that name, takes the opportunity of writing
V. strebelit instead on the explanation to the plate. This mexicanus
=strebelii is 51 mm. long, 153 broad, with the female orifice 13
min. from sole and almost exactly equidistant from each end. On
p. 316 of the same work, Semper describes a true mexicanus Pfeff.,
which he had from Strebel. It was found in Vera Cruz, and was
whitish-flesh, only 20 mm. long, with the 9 orifice a little hind of
the middle. If this specimen was really of the same species as orig-
inally described in 1873, it must have been somewhat immature.
In the same work of Semper, p. 295, appears a Chilian species, V.
decipiens Semper. This is supposed to be also a native of Mexico,
but I think the latter habitat must be accepted with some reserva-
tion; unless perchance, it has reached there accidentally through
human agency. It is dark yellowish-brown, with the mantle black-
spotted, 42 mm. long, 163 broad, 9? orifice 1 mm. from sole, and
somewhat anterior to the middle. This V. decipiens is very much
like the Chilian V. adspersa Heynemann; so much so that one
strongly suspects that they are forms of one species. They were
published nearly at the same time, but I think adspersa has prior-
ity. Since Semper’s work no further additions have been made.
In the British Museum are two other forms, which are the more
interesting in that they represent new localities. They do not seem
to be precisely identical with any of the described species, but all
things considered, it seems preferable to leave them unnamed for
the present. Descriptive notes are appended :
(1.) Veronicella sp. nov., vel mexicana var.
Long. (in alch.) 424, lat. 203, sole lat. 10 mm.. @ orifice from
head 22 (almost. median), from sole2 mm. Sole rather rounded
posteriorly, not projecting beyond mantle, finely and closely trans-
versely striate. Mantle above rugose-granulose, not at all papil-
late; color pale grayish-ochreous, above obscurely gray mottled,
with the slightest indication of a dorsal and lateral dark band, only
noticeable when looked for. Back arched, rounded. Upper ten-
tacles grayish, lower pale ochery.
THE NAUTILUS. 143
Honduras. Collector unknown. Heynemann had seen it when
he visited the museum, and had written “ nov. sp.?”
(2.) Veronicella sp. nov., vel punctatissima subsp.
Long. (in alch.) 414, lat. 12, sole lat. 4 mm. 9 orifice from
head 21 (almost median), from sole 2} mm. Sole very narrow,
rounded behind, not projecting posteriorly, regularly and strongly
transversely striate its edge longitudinally grooved. Mantle above
thickly but rather irregularly impressed punctate, not papillate.
Superior tentacles gray, lower pale ochrey.
Jaw brown, not very dark, with 36 very strong ribs. Penis ta-
pering. Color variable, as follows: ©
(a) Pale ochreous, above brown from thick brown mottling, with a
slightly indicated but quite observable pale dorsal line. Below
with sparse black mottling. Six examples.
(b) Similar, but with more or less black spotting also above, though
sparse. Four examples.
(c) Similar, but dark brown above, no pale dorsal line.
Panama, Volcan de Chiriqui. Collector unknown.
The interesting point may here be noted, that whereas the Nicar-
aguan olivacea and the Honduras species are typically Central Am-
erican forms, and show a good deal of resemblance to the species of
the greater Antilles, the Panama species is quite different, and be-
longs with the series of the lesser Antilles, Trinidad, ete.
NOTES AND NEWS.
Unio CARrIosus and ocHRACEUS.—By an unfortunate oversight,
the wood-cuts of these two species in the March number were trans-
posed. The figure on page 121 is U. cariosus; that on page 122 is
U. ochraceus.
ByTHINIA TENTACULATA.—A new locality for this species is
Black Lake, Holland, Michigan, Mr. L. H. Streng having collected
adult and young in all stages of growth there.
Mr. H. E. Sarcenr, having spent some weeks in New England,
has returned to his home at Woodville, Ala.
Mr. James M. De Laney has removed from Rochester to South
Livonia, Livingston Co., N. Y.

DisTRIBUTION OF THE LAND AND FRESH-WATER MOLLUSKS OF
THE West INDIAN Recron, and their Evidence with Regard to
Past Changes of Land andSea. By Charles Torrey Simpson (Proc.
U.S. Nat. Mus., X VII, 1894).—After a statement of the geographic
facts in regard to the region, and the depths of sea between and
around the main islands, Mr. Simpson considers the means of distri-
bution of the land and fresh-water mollusks from island to island,
concluding that while some forms have been transported by drifting
trees, etc., the main means of transport has been by means of former
direct land connection of islands now separated. ‘There appears
to be good evidence of a general elevation of the Greater Antillean
region, probably some time during the Eocene, after most of the im-
portant groups of snails had come into existence, at which times the
larger islands were united, and there was land connection with Cen-
tral America by way of Jamaica. * * * At some time during
this elevation, there was probably a landway from Cuba across the
Bahama plateau to Florida, over which certain groups of Antillean
land molluskscrossed. * * * There followed a period of general
subsidence. During this the island of * * Jamaica was first
isolated, then Cuba, and afterwards Haiti and Puerto Rico were
separated. The subsidence continuing until only the summits of the
mountains of the four Greater Antilles remained above water; then
followed another period of elevation which has lasted until the pres-
ent time. * * The Bahamas have appeared above the surface of
the sea, either by elevation or growth, and have been peopled by
forms drifted from Cuba and Haiti. The lesser Antilles have been
peopled, for the most part, from S. America.” These conclusions
are based upon tables showing the distribution of species and genera
on the various islands, and the later movements are supported by
well-known geological facts. The evidence for the earlier elevation
should be compared with Spencer’s “ Reconstruction of the Antillean
Continent” (Bull. Geol. Soc. Amer., VI, Jan., 1895), founded upon
a study of the supposed sunken river-valleys, and altogether support-
ing Mr. Simpson’s conclusions. That the West Indian region ac-
tually stood two miles above its present level, as claimed by Spencer,
is a proposition requiring much more proof than has been offered, to
bring it out of the realm of mere suggestion or hypothesis ; and we
are certainly not prepared to endorse it; but the orogenic move-
ments required to fulfill the conditions asked by Mr. Simpson are far
more moderate, and, it seems to us, by all odds the most reasonable
explanation of the facts of distribution. Mr. Simpson’s paper con-
cludes with the descriptions of Sagda maxima, Neocyclotus bakeri,
Lucidella costata and Pleurodonte bowdeniana n. spp., from Jamaica,
the latter three from the Miocene beds at Bowden.
