ABSTRACT
Collecting in wet leaf-litter microhabitats in the Great Craggy
Mountains and Black Mountains of western North Carolina
uncovered juvenile shells and live adults of the rare snail
Vitrea clingmani Dall in Pilsbry, 1900. This newly available
material Allows the description of the radula, juvenile shell,
and reproductive system of this species, providing characters
fora phylogenetic analysis, which suggests reassignment of
the species from the genus G lyphyalinia (Glyphyalus) to
Pilsbryna. This new placement is corroborated by COI se-
quence data. Surveys near the type locality expand the known
range of Pilsbryna clingmani and suggest this species is en-
demic to spruce-fir aml northern hardwood forests at eleva-
tions above 1500 m in the Black Mountains and contiguous
Great Craggy Mountains of western North Carolina where it is
further restricted to wet leaf litter microhabitats, making it
one of the most narrowly distributed snail species in eastern
North America.

Mountains, spruce-fir forest, seeps
INTRODUCTION
Pilsbryna clingmani, under the name Glyphyalinia clingmani,
is listed as a species of concern by the U.S. Fish and
Wildlife Service and a threatened species ranked as
critically imperiled in North Carolina (LeGrande et al.,
2008), but very little is known about its range and habitat.
What little is known is based lar gely on reports from two
brief surveys of Mount Mitchell. North Carolina, by ex-
perienced malacologists (Pilsbry, 1900; Walker and
Pilsbry, 1902) which resulted in a handful of specimens
now scattered among several museum collections. This
scarcity of records suggests the species is not widely
distributed or may require or prefer microhabitats not
commonly or easily sample -d. In the past century the
forests of Mount Mitchell have undergone profound
change and during that time Pilsbryna clingmani has been
reported only once (Hubricht, 1970).
Non-marine mollusks have the unfortunate distinction
of having the highest number of recent extinctions
documented in any animal group (Régnier et al., 2009:
Cowie et al., 2017). Many of these were extinctions of
terrestrial snails endemic to islands but snails restricted to
other geographically isolated habitats are vulnerable to
habitat loss that might lead to extinction. Several of
eastern North America’s most narrowly distributed snail
species (Hubricht, 1985) occur in southern spruce-fir
forest (Pilsbry, 1940; 1946; 1948). This community is
dominated by c canopy species Abies fraseri (Pursh, 1814)
and Picea rubens Sargent, 1898, and is limited to seven
disjunct stands at peaks above 1500 m elevation in the
southern Appalachian Mountains. Pilsbryna clingmani is
known from one of these stands of southern spruce-fir
forest at the summits of the Black Mountains (Walker and
Pilsbry, 1902). All published records were based on
specimens collected prior to 1902 within 5 km of Mount
Mitchell at elevations above 1900 m. Shortly afterwards
approximately 50-65% of the spruce-fir forest on the
Black Mountains was logged between 1912 and 1927
(Pyle and Schafale, 1988). Loss of forest cover prompted
reforestation efforts, which unfortunate ly included non-
native trees (Minckler, 1940). These non-native species
are probably the source of the catastrophic introduction of
the balsam woolly adelgid, Adelges piceae (Ratzeburg,
1844), which was first reported on Mount Mitchell in
1957 (Speers, 1958). Nearly all mature fir trees in the
Black Mountains had succumbed to A. piceae by 1988
(Dull et al., 1988), opening large portions of the forme tly
dense canopy and exposing re al spruce, Picea rubens, to
damage similar to thinning mortality (Nicholas et al.,
1992). Acid mists eoeted with air Bees reported
from Mount Mitchell (DeFelice, 1997) probably cause
additional reduction in growth of red spruce by lowering
availability of calcium (Jacobson et al., 1990). The more
open canopy probably produces changes in soil moisture

and leaf litter cover that may negatively impact moisture-
dependent land-snails.
Recent land snail surveys in wet leaf litter micro-
habitats in the Black Mountains and contiguous Great
Craggy Mountains in western North Caroline found
specimens of Pilsbryna clingmani. Rediscovery of this
species permits its redescription, comparison with
other species, reassignment to the genus Pilsbryna,
and clarification of its geographic range and habitat
requirements.
MATERIALS AND METHODS
Twenty-nine survey sites that were likely to contain snails
were chosen along easily accessible roadways and trails in
the Black Mountains and Craggy Mountains near Mount
Mitchell, with special attention given to seeps in both
open and forested habitats. An additional 41 sites were
sampled in other mountain ranges in western North
Carolina. Specimens were hand-collected from the leaf-
litter soil interface during 1 hour searches within sites of
approximately 100 m> - Aaldktioreall specimens were picked
from approximately 1 liter samples of leaf-litter sievings
gathered from each site. Live collected animals were
mereoted overnight in a suspension of water containing
a 1 cm length of mentholated cigarette and then preserved
in 75% ethanol. Gross anatomical dissections were made
under 75% ethanol using a dissecting microscope. Iso-
lated reproductive systems were stained with Harris’
haematoxylin and Semichon’s aceto-carmine stain, cleared
with glycerin, and mounted on slides. Drawings of the shell
and reproductive anatomy were made with the assistance
of a camera lucida, and measurements taken using an
ocular micrometer. Greater and lesser shell widths, shell
height, aperture width, aperture height, umbilical width,
spire width, and number of whorls were measured as
described by Slapcinsky and Coles (2004) and shown in
Figures 1— 3. Means and standard deviations are reported
Fan all measurements of 14 undamaged adult specimens.

whorls were presumed to be mature and two were
dissected and confirmed to have adult reproductive
structures. Radulae were isolated from dissected buccal
masses using a saturated KOH solution. Scanning elec-
tron micrographs of shells and radulae were made using
a HITACHI S-4000 FE-SEM. All available specimens a
Pilsbryna clingmani in the collections of the Academy of
Natural Sciences, Philadelphia (ANSP); Carnegie Museum
of Natural History, Pittsburg (CMNH); Field Museum of
Natural History, Chicago (F MNH); National Museum of
Natural History (USNM): Schiele Museum of Natural
History, Gastonia, North Carolina (SMNC); University of
Florida, Florida Museum of Natural History, Gainesville
(UF); and in the private collections of Harry G. Lee,
Jacksonville, Florida (HGL) and Amy Van Devender (ASV)
were examined. Anatomical terminology follows Tompa
(1984). Higher-level systematics follows Bouchet et al.
(2017).
Morphological characters derived from dissections
combined with those gleaned from published figures
of reproductive systems, radulae, and shells (Baker,
1929a, b; Pilsbry, 1946; Slapcinsky and Coles, 2004)
were used to build a matrix of 28 characters (Table 1)
for 47 oxychilid species (Table 2). Characters were treated
as unordered. A phylogenetic analysis was performed
using the optimality criterion of parsimony in Mesquite
version 3.2 (Maddison and Maddison, 2017).
DNA was extracted from 1 mm?® samples of foot tissue
using a solution of 10% Chelex beads (Bio-Rad Labora-
tories) in sterile water heated to 65°C for 4 hours. DNAses
and other protein contaminants were digested using
Proteinase K. A 655 bp nucleotide fragment of cyto-
chrome oxidase I (COI) was amplified using the primer
pairs LCO1490/HCO2198 (Folmer et all, 1994) and
GoTaq DNA Polymerase (Promega, Madison, Wisconsin).
Sequencing was performed in both directions at the
University of Florida, Interdisciplinary Center for
Biotechnology Research or the Canadian Centre for
DNA Barcoding (CCDB), using their standard pro-
cedures. Primer regions were acted and sequences
edited and aligned using Geneious version 6.1.7 (Kearse

SYSTEMATICS
Family Oxychilidae Hesse in Geyer, 1927
Family Placement: Traditionally, most North Ameri-
can limacoid species have been placed in a morphologi-
cally heterogeneous Zonitidae (Baker, 1931; Pilsbry, 1946;
Riedel, 1980). A cladistic analysis of Limacoidea using
reproductive, muscular, nervous, lung, digestive, edemal
body, and shell characters cast doubt on nine monophyly
of Zonitidae (Hausdorf, 1998) and elevated most of its
component subfamilies. Paravitrea and its then syno-
nym Pilsbryna (see Riedel, 1980), were excluded
from Vitrininae, now Pristilomatidae, and moved to
Daudebardiidae Kobelt, 1906. The genera Glyphyalinia,
Nesovitrea, Mesomphix, and Vitrinizonites were also
placed in Dauderbardiidae. More recently, Daudeberdiinae
has been treated as a subfamily within Oxychilidae
(Bouchet et al., 2017). However, family level relation-
ships of taxa formerly treated as Zonitidae are not fully
resolved and remain controversial (Schileyko, 2003,
Welter-Schultes, 2012).

Diagnosis: A large Pilsbryna with an adult shell of
4.9-5.4 whorls that is 5.0-7.8 mm in width and
2.6-3.9 mm in height. Early whorls increase slowly and
regularly in size but whorl expansion increases in the body
salar of the adult. Shells with fewer than 2.5 whorls
contain a sinuous parietal lamella and two spirally
arranged series of basal and palatal nodules that can ex-
tend a full whorl into the aperture.
Description: — Body coloration dark blue-grey (Figure 4).
Shell is depressed- helicoid, umbilicate, glossy, faneincent
brown, and sculptured with dense and irregularly spaced,
indented axial lines that become more fre quent on the last
quarter of the body whorl of the adult (Figures 5—8). Adult
shell (n= 14) 5.0-7.8 mm (mean=6.2+0. 9 mm) in greater
width, 4.1-6.3 mm (mean=5.0+0.7) in lesser sarki and
2.6-3.9 mm (mean=3.1+£0.5 mm) in height with 4.9-5.4
(mean = 5.1+0.1) slowly expanding eee The final 1/3 of
the Tyadhy ine of the adult expands more rapidly than
previous whorls; the lesser/greater width ratio is 0.80—0.87
(mean=0.85). The arlene also expands rapidly in the
body whorl of the adult, reaching a width of 0.7 to 1.0 mm
(mean = = 0.9+0.1). Spire width is 2.4-3.9 mm (mean=3.0+
0.4). The aperture is ovate; aperture width is 2.74.0 mm
(mean=3.2=+0.5), aperture height is 2.1—3.0 mm
(mean=2.5+0.3). Shells of immature animals with fewer
than 2.5 whorls have a sinuous parietal lamella and a series
of paired basal and palatal nodules (Figures 9-10). All
traces of nodules and lamellae are resorbed in adults.
Reproductive Anatomy: Two specimens were exam-
ined (UF 292689). The basal half of the penis is smooth
while the apical half bears numerous small thorn shaped
papillae (Figure 11). The penial retractor muscle is apically

roughly 2/3 the diameter of the penis and inserts laterally at
the apex of the penis. The epiphallus is sculptured with
longitudinal folds and tapers slightly before widening at the
junction with the narrow vas deterens. The spermatheca i is
ovate, and the narrow spermathecal duct expands slightly
basally. No sign of perioviducal or perivaginal glands were
observed. While most characters varied little in size, the
albumen gland and oviduct were larger in one of the two
specimens that were dissected.
The central tooth of the radula is symetrically tricuspid,
the mesocone expands slightly above the ectocones, then
tapers slowly to the apex (Figure 12). The ectocones are
short and sy mmetrical, less than % the total height of the
tooth. The three laterals are tall, slender, and asymmet-
rically tricuspid and slightly convex proximally and con-
cave distally. The endocone is tall, about % the height of
the mesocone while the ectocone is less than 4% the height
of the mesocone. The marginals are tall, slender, emooths

Remarks: Binney (1885) identified Hemphill’s speci-
men from Clingham’s [sic] Peak as Zonites wheatleyi,
which is treated as a species of Glyphyalinia (Hubricht,
1985). Dall (1898) gave the varietal name Vitrea clingmani
to Hemphill’s shell but did not provide a figure or de-
scription. Pilsbry (1900) indicated that Dall’s new name
was a nomen nudum and included a description, a refer-
ence to a type lot, USNM 38910, and a figure, all of which
were provided by Dall. In addition to the holotype, which
is consistent with Dall’s description, measurements, and
figure (Pilsbry, 1900, Figure 2), lot USNM 38910 also
emiteinadl a specimen of Paravitrea petrophila (Bland,
1883). This is probably the specimen Dall had compared
to his new species in the original description and this shell
is now USNM 38910a.
Synonymy of Vitrea approxima Walker and Pilsbry,
1902: Vitrea approxima was described based on two
specimens collected by James Ferris and Bryant Walker
in Wilsons Goveon Mount Mitchell (Walker and Pilsbry,
1902) and does not appear to have been collected since.
One of these specimens (Figures 16-18) was deposited
by Walker (ANSP 83260) and selected as the lectotype
by Baker (1962) based on original measurements, but
cited incorrectly as ANSP 82360. The fate of the second
specimen is unknown. Vitrea approxima differs from
Pilsbryna_ clingmani, which is larger, and Pilsbryna
vanattai, which is smaller, by having a relatively small
umbilicus and lacking a rapidly expanding body whorl.
Hubricht (1974) synonymized Vitrea approxima with
Pilsbryna clingmani (as Glyphyalinia), suggesting unique
attributes of “the lectotype were the result of shell
damage early in life. While the lectotype (Figures 16-18)
has shell damage between the second and third whorls, it
does not appear to be seriously deformed. It is a juvenile
of only 4.6 whorls that has not reached the stage of rapid
body whorl expansion that would result in a fared body
whorl and relatively large umbilicus that is common in
adults of all Pilsbryna species (Slapeinsky and Coles,
2004) and it appears to be a juvenile specimen of Pils-
bryna clingmani.
Habitat and Distribution: All previous records of
Pilsbryna clingmani were from spruce-fir forest above
1800 m elevation on the peaks of the Black Mountains
near Mount Mitchell, North Carolina (Walker and Pilsbry,
1902). My surveys of the Craggy Mountains (Figure 19)
extend the range of P. dlinenvan south to near Craggy
Gardens picnic area. This also extends the ele eatonal
range of the species down to 1500 m and into northern
hardwood forest. Like other Pilsbryna species, P. clingmani
is common in wet leaf-litter in seep runs and ditches on wet
soil or under wood. However, at higher elevation sites on
Mount Mitchell, it is also common among grasses and

Devender, and Denise Furr, personal communications).
Comparative Remarks: Placement of Vitrea cling-
mani within Pilsbryna is supported by a phylogenetic
analysis of 28 morphological characters from 47 species of
Oxychilidae ( Figure 20). Pilsbryna clingmani has a series
of pariet tal aeratulles that are fused into a parietal lamella
which is resorbed in adults and has a shell of approxi-
mately 5 whorls that expands slowly at first and more
rapidly in the body whorl of adults: these are synapo-
morphies that unite Pilsbryna species within Oxychilidae.
Juvenile Pilsbryna clingmani shells bear basal and parietal
nodules found in Pilsbryna and Paravitrea but not in
other oxychilids.
Pilsbryna clingmani does not share certain characters
found in other cull shelled oxychilid genera. The la-
mellae of Pilsbryna are not grouped axially and separated
by % to “3; whorl as in Paravitrea. Glyphyalinia sensu
stricto have shells textured with widely and regularly
spaced axial indentations, reproductive systems woitin per-
ivaginal and perioviducal glands, and radulae with serrated
marginal teeth and bicuspid lateral teeth; none of these
characters is found in Pilsbryna clingmani. Nesovitrea and
some Glyphyalinia species have penises with subapical
oval pilasters and shells with approximately 4 whorls that
expand rapidly and consistently unlike Pilsbryna which
have apical thorn shaped papillae and shells of 5 whorls only
the last of which expands rapidly.
Both morphological (Figure 20) and molecular data
(Figure 21) support placeme nt of Pilsbryna clingmani
within Pilsbryna. Pilsbryna clingmani has a spiral row of
nodules at basal and palatal positions in addition to the
sinuous parietal lamella that defines all described Pils-
bryna. The basal nodules are not fused into a lamella as
in P. quadrilamellata. Unlike Pilsbryna clingmani, pala-
tal nodules are lacking in P. castanea, P. aurea, and
P. quadrilamellata. Of the species with palatal nodules, P.
nodopalma has flattened blade shaped basal and palatal
nodules unlike the peg-shaped nodules in P. clingmani,
which are similar to those of the much smaller P. vannattai.
DISCUSSION
My survey is the first to report Pilsbryna clingmani from
northern-hardwood forest in the C raggy Mount uins, in-
dicating that the species is not restricted to the Black
Mountains or to spruce-fir forest. However, this species
was only observed at elevations above 1500 m and was not
found in well-sampled cove-forest at lower elevations in
the same mountain ranges, where it is replaced by P.
vanattai (Slapcinsky aunel Calle. 2001). Furthermore, the
species was not found in 41 sites sampled outside of the
Black Mountains and Craggy Mountains and there are no
other records of the species outside of these mountain
ranges (Hubricht, 1985). The majority of the distribution
of P. clingmani occurs in spruce-fir forest which has ex-
perie neal high mortality as a result of 60 years of adelgid
impact (Dull et al., 1988). However, P. clingmani is still
commonly encountered in damaged spruce kr forest near
the summits of the Black Mountains and it appears that
the paucity of observations of this species in the past
century are the result of low sampling effort. eeu
P. clingmani is common among grass and leaf litter i
open areas near the summit of Mount Mitchell (see
above). These exposed habitats are normally too dry for
Pilsbryna species (Slapcinsky and Coles, 2004). Tt is
possible that high elevation mist on Mount Mitchell
maintains soil moisture that is necessary for this Pilsbryna
species even in open habitats. Adc litional sampling is
necessary to determine if P. clingmani also inhabits other
high elevation open habitats such as heath balds. The
occurrence of this species in acidic leaf-litter with high

rates of soil leaching on acid igneous rocks in conifer forest
and open habitats suggests it is an acidophile (Nekola,
2010). Ecological data are needed to determine the
moisture, cover, and microhabitat requirements of this
rare species. This is especially important because global
warming is likely to reduce isolated high elevation spruce-
fir and nomhenie hardwood forest esl Leet F in the southern
Appalachian Mountains. The narrow distribution of P.
clingmani in wet microhabitats above 1500 m on the peaks
of ‘the Great Craggy and Black Mountains make this
species especially vulnerable and a species of special
concern to conservation biologists.

that are usually > 20 mm in shell width and the much
smaller Glyphyalinia, Nesovitrea, Paravitrea, and Pils-
bryna, which are usually < 10 mm in shell width. Unlike
most of the other genera, Pilsbryna is morphologically
well defined, composed of morphologically similar species
with similar habitats in reliably moist leaf litter micro-
habitats. The other small bodied genera Glyphyalinia,
Nesovitrea and Paravitrea are morphologically and eco-
logically diverse and probably require taxonomic revision
using additional morphological and molecular characters.

THE 2018 R. TUCKER ABBOTT VISITING CURATORSHIP
The Bailey-Matthews National Shell Museum is pleased to invite applications for the 2018 R. Tucker Abbott Visiting
C uratorship. The Curatorship, established originally in accordance with the wishes of the late Dr. R. Tucker Abbott.
Founding Director of the Shell Museum, is awar ded annually to enable malacologists to visit the museum for a period of
one week. Abbott Fellows are expected, by performing collection-based rese arch, to assist with the curation of portions of
the Museum’s collection and to provide one talk for the general public. The Museum collection consists of marine,
freshwater, and terrestrial specimens. The entire collection has been digitally catalogued and the catalogue is available at

ABSTRACT
Examinations of materials deposited in the Marine Biological
Museum, Chinese Academy of Sciences (MBMCAS) revealed
two deep-sea calliotropid species. Calliotropis infundibulum
(Watson, 1879), trawled from an abyssal plain in the South China
Sea (17°15’ N, 111°20' E) ata depth of 1238 m, is anew record of
the species for Chinese waters. Calliotropis yapensis new ae
cies, collected at the Yap Seamount (8°55’ N, 137°48' E),
a depth of 1119 m, is distinguished from its congeners by ee
a globular shell (height/width ratio=0.95), sculpture d with
granular spiral cords an prominent, densely spaced axial ribs.
Phyloge netic analysis using 633 bp of the cytochrome oxidase c
subunit I (COI) gene of Calliotropis yapensis new species
supports its systematic placement within the genus.
Additional Keywords: Mollusca, Vetigastropoda, Seguenzioidea,
South China Sea, Yap Seamount
INTRODUCTION
Based on the distinctive shell morphology and radular
features, Hickman and McLean (1990) established
Calliotropidae (as the tribe Calliotropini) to group some
species previously under the Margaritinae, Angariinae,
Monodontinae, Calliostonmatinae and Solariellinae.
Members of the family are very characteristic among
the Seguenzioidea by having a thin shell with an
unthickened outer lip, aperture without denticles or
lirae, radula with a reduced rachidian and three lateral
teeth per half row. Calliotropis Seguenza, 1903 is the
most speciose genus in this family, with more than
150 valid Recent species predominantly distributed in
the Indo-West Pacific region (e.g. Australia: Jansen,
1994: New Zealand: Marshall, 1979: Solomon Islands:
Vilvens, 2007; Japan: Okutani, 2000; Philippines: Poppe
et al., 2006; China: Vilvens, 2007: Indonesia: Hickman,
2016).
Although many surveys have been carried out during
the last few decades (e. g. Bartsch, 1942; Bouchet and
Warén, 1985; Bouchet and Poppe, 1988; Marshall, 1988;
Okutani and Iwasaki, 2003: Kantor et al., 2013), the
knowledge of deep-water malacofauna of the western
Pacific is still far from sufficient. Almost every survey is
bound to discover new taxa and great numbers of new
distributional records. Over the past decade, more than 50
Calliotropis species have been described as new from the
deep waters of the western Pacific region (Poppe et al.,
2006: Vilvens, 2006; 2007; Hickman, 2016). These find-
ings strongly suggest that many more new deep-sea
species are awaiting description.
In recent years, several deep-sea surveys have been
carried out by Institute of Oceanology, C hinese Academy
of Sciences (IOCAS). During these surveys, two species of
Calliotropis were sampled: one represents a new record
for Chinese water and another one belongs to an unde-
scribed species. In present study, we describe and illus-
trate these two species.
MATERIALS AND METHODS
The studied specimens of Calliotropis infundibulum
(Watson, 1879) were trawled from the South China Sea,
whereas the specimen of Calliotropis yapensis new spe-
cies was collected by the mechanical arm of the ROV
FaxiAn (based on mother-ship R/V Kexuey!) from Yap
Seamount. Specimens are deposited in the Marine Bi-
ological Museum, Chinese Academy of Sciences
(MBMCAS).
Morphological Methods: Shell morphology was ob-
served under a stereomicroscope, and photos taken using
a digital camera. The soft parts of the new species were
retracted too deep inside the shell. Thus, it would be
difficult to extract the soft parts and consequently the
radula, without breaking the shell. Shell measurements
were taken using a caliper with accuracy of 0.1 mm.
Molecular Procedures: One specimen of Calliotropis
yapensis new species was used for molecular analysis.

to the manufacturer instructions. DNA was eluted in
elution buffer and stored at -20°C until use. The COI
region was amplified by polymerase chain reaction
(PCR) using the primers LCO1490 (forward: oe
GGTCA: ACAAATG ATAAAGATATTGG-3) and HCO2198
(reverse: 5/-TTAACTTCAGGGTGACCAAAAAATCA-3)
(Folmer et al., 1994). PCR reactions were carried out in
a total volume of 50 wl, including 1.5 mM MgCls,
0.2 mM of each dNTPs, | wM of both forward and reverse
PCR primers, 10Xbuffer and 2.5 U Taq DNA poly-
merase. Thermal cycling was performed with following
conditions: 95°C for 3 min (initial denaturation), followed

Page 15
by 35 cycles of 95°C for 30s (denaturation), 40°C for 30s
(annealing), 72°C for 60s (extension) and a final extension
at 72°C for 10min. PCR products were verified on
a GelRed-stained 1.5% agarose gel and purified with the
Column PCR Product Purification Kit (Shanghai Sangon,
China). Purified products were sequenced in both directions
using the BigDye Terminator Cycle Sequencing Kit (ver.
BIL Applied Biosystems) and an AB PRISM 3730 (Applied
Biosystems) automatic sequencer. The sequence has been
deposited in GenBank (Accession number: MF499154).
Sequence alignments were generated using Clustal X
(Larkin et al. 2007). Neighbor- -joining (NJ) tree was
performed by MEGA 6.06 (Tamura et al. 2013), using
Kimura 2-parameter (K2P) model (Kimura, 1980).
Bootstrap analyses were performed with 1000 replications.

Description: Shell (Figures 1-5) conical (H/W=1.0),
very thin (aperture margin 0.2 mm thick), with 7 whorls,
low-spired, spire 36% of shell height. Shell surface
nacreous, indicative of exfoliation of outer shell layer
that probably occurs during collection and/or preservation.
Suture strongly impressed. Spire whorls angularly convex,
with two be ie d spiral cords separated by wide, smooth
interstice. An additional spiral cord occurring above
periphery of body whorl. Axials obsolete but still visible
near spiral cords. Basal area with 4 spiral cords, separated by
regularly spaced interstices. Interstice region sculptured
with numerous oblique, curved axial isis ts. Umbilicus
deep, wall sculptured with prominent axial ribs.
Material Examined: Two empty shells, MBM280611,
South China Sea, 17°15’ N, 111°20' E, 1238 m deep,
sandy bottom, collected by Agassiz trawl from the abyssal
plain (Mother-ship R/V KEXxuEYI, IOCAS), 13 Se pte »mber
2011.
Distribution: Atlantic North America (Abbott, 1974):
Caribbean (Watson, 1886); Brazil (Dall, 1889); South
Africa (Martens, 1903): Marion Island (Prince Edward
Islands), Atlantic-Indian-Antarctic Basin (Watson, 1879):
north-eastern New Zealand (Marshall, 1879), Japan
(Okutani, 2000) and China (this study). Depth range
230-3259 m (Clarke, 1962).
Remarks: No significant morphological differences
could be found to separate the studied specimens from
the photographs of the holotype (Cernohorsky , 1977)
and syntypes (Vilvens and Swinnen, 2008).
Calliotropis infundibulum (Watson, 1879) (Type lo-
cality: Prince Edward Island, Indian-Atlantic Ridge area,
46°46 S, 45°31’ E, 2514 m) is regarded as broadly dis-
tributed throughout the Indo-Pacific and tropical western
Atlantic. However, the eastern Pacific barrier and the
Mid-Atlantic barrier, and the presence of cold waters
around polar or temperate margins of continents, have
played important vicariant roles in the evolutionary history
of tropical marine taxa (Duda and Kohn, 2004). These
vicariant factors suggest that the spe cimens identified as
Calliotropis infundibulum from Indo-West Pacific are
probably not conspecific with those from the Atlantic.
Previous authors compared the specimens from the two
localities, and found no reason for further separation
(Marshall, 1979: Vilvens and Swinnen, 2008). These
studies, however, have mainly focused on shell mor-
phology and lack detailed information on anatomical and
molecular characters, although a radula from New Zea-
land was described by Mar Shall (1979) and a soft part from
America described by Dall (1889b). Consequently, iden-
tification of Indo-Pacific specimens must be tentative until
Page 16
THE NAUTILUS, Vol. 132, No. 1
supporting antomical and molecular data are available for
comparison.
At a morphological level, although some variations exist
among the shells from different localities e.g., shell size
varies from 15.3 mm to 23.5 mm, spire depressed to high,
suture shallowly to deeply compressed, etc., serial in-
termediate forms may present (Vilvens and Swinnen,
2008). The main sculpture characters of this species are
relatively consistent, e.g., spire whorl with 2 granular
spiral cords and body whorl with 3 ones, with the adapical
one strongest, axial ribs obsolete but still visible near the
granules; basal area with 4 thin g granular spiral cords, the
innermost one with strong nodules; umbilicus broad,
deep, with axial ribs, no spiral cords.
To date, about five species of the genus have been
reported from the South China Sea including Calliotropis
annonaformis Lee and Wu, 2001, Calliotropis scalaris
Lee and Wu, 2001 and Calliotropis chunfuleei Chino,
2014 from Pratas Island at depths of 400-500 m,
Calliotropis philippei Poppe, Tagaro, and Dekker, 2006
from off the Philippines at depths of 550-884 m, and
Calliotropis helix Vilvens, 2007 from Taiwan at depths
of 790-904 m. Among them, Calliotropis helix most
resembles the present studied specimens in general
shape, but differs in having distinct sculpture and a much
more depressed body whorl. Calliotropis infundibulum
(Watson, 1879) is recorded for the first time from the
coast of China.
Calliotropis yapensis new species
(Figures 6-11)
Description: Shell (Figures 6-10) solid (aperture
margin ~1.0 mm thick), large for the genus, 25.0 mm high
and 26.2 mm wide (height/width=0.95), umbilicate; spire
low, broadly conical, height 66% of width; suture mod-
erately impressed. Body egal globular, occupying 2/3 of
shell Jer igth. Exterior shell layer very thin and translucent,
underlying nacre visible. A very thin, brownish intritacalx
well pre eRe on body whorl. Protoconch unknown.
Teleoconch of 6 regularly expanding convex whorls.
Subsutural ramp broad and ornamented by axial ribs.
Sculpture of granular spiral cords with prominent,
densely packed prosoeline axial ribs between interstices.
Intervals between ribs twice as broad as ribs. In addition to
three spiral cords on spire whorl, a fourth finely granular
spiral present, concealed by suture throughout ¢ ‘aowiah
becoming exposed on periphery of body whorl. Nodnles
very pronounced, rounded or slightly sharp. Number of
nodules on penultimate whorl: 24 on first cord, 25 on
second cord, 30 on third cord; number of nodules on body
whorl: 33 on first cord, 38 on second cord, 45 on third
cord, 75 on fourth cord. Basal area with 6 finely beaded
spiral cords, innermost one strongest, bordering the
umbilicus, interstices between cords with secondary
axial riblets. Umbilicus wide, fully covered by reflected
projection of parietal and columellar callus, wall sculptured
with thin axial riblets. Aperture subquadrate, 1.2 times
higher than spire, backward-sloping, inside yellowish with
iridescence. Parietal lip with a very thin, translucent callus.
Operculum (Figure 11) paucispiral, sub-circular in shape,

Type Locality: Yap Seamount, Say IN, IBA" 18,
foraminiferal ooze, 1119 m depth.
Type Material: Holotype. MBM285092, collection
number: Y30057, station: FX-DIVE 18, Yap Seamount,
8°55’ N, 137°48’ E, foraminiferal ooze, 1119 m deep, 18
December 2014.
Distribution and Habitat: Only known from the type
locality, living on foraminiferal ooze bottom.
Etymology: The name of new species refers to its type
locality.
Remarks: Calliotropis yapensis new species is char-
acterized by a large shell with convex teleoconch whorls,
shell surface sculptured with granular spiral cords and
fine, dense, regularly spaced axial ribs. These features can
easily separate new species from most species of the
genus. Calliotropis yapensis new species is in general shell
shape most similar to Calliotropis ammos Valvene! 2012
from French Polynesia, which also has low spire and
rounded body whorl. Calliotropis ammos Vilvens, 2012,
however, differs from the new species in having a smaller
shell (height 294-945 mm, width 21.4-23.8 mm) with
a larger number of teleoconch whorls (6.9-7.1), and a
lower aperture (height/height of the aperture 2.55—3.03
vs. 2.27 in new species). In addition, Calliotropis yapensis
new species can be separated from Calliotropis ammos
Vilvens, 2012 in having a very thin exterior shell layer
through which the underlying nacre can be seen, 6
cmnteaG of 5 spirals on the base, prominent axial ribs
present between the spirals, and an aperture that
not transversely elongated (Vilvens, pers. comm.).
Calliotropis blacki Mleneslheall, 1979 and Calliotropis
derbiosa Vilvens, 2004 may be also confused with
Calliotropis yapensis new species, but differ in

having much more angulate teleoconch whorl and
depressed body whorl.
Molecular Analyses: One sequence for the COI re-
gion of Calliotropis yapensis new species was obtained.
After manual adjustment, the length of the partial COI
sequence of new species is 633 bp. “The Neighbor-joining
(N]) tree (Figure 12) was reconstructed using available COI
sequences feeorta this study and GenBank. The alignment
of COI had a total 594 bp, without insertions and alate tions.
The NJ tree shows that the new species fall into the genus
Calliotropis in which Calliotropis yapensis new species
together with other Calliotropis spp. form a well-supported
clade, supporting its placement within Calliotropis. The
phy logenetic tree also supports monophyly of a group of
5 Calliotropis species within the family. Within the available
sequences from GenBank, Calliotropis yapensis new species
is closest related to Calliotropis pagodiformis, with 9%
pairwise distance, whereas the pairwise distances among
Calliotropis yapensis new species and other species of
Calliotropis are 10-12% (see Table 1).
In addition to the present new species, other two basal
(Vetigastropoda) species were collected together during
the survey, including a pleurotomariid species, Bayero-
trochus delicatus Zhang, Zhang and Wei, 2006, and
a undescribed colloniid species, Homalopoma sp. The
three species had never yet been found elsewhere, and
thus were considered potential Yap Seamount endemics.

ABSTRACT
The geographical distribution of the jumping snail Ovachl-
amys fulgens Gude, 1900, originally described from Loo-Choo
Island, is expanding rapidly throughout the tropics. The full
extent of the environmental damage caused by the in-
troduction of this exotic species is ill unknown. So far, it has
been implicated in damage to orchids and horticultural plants.
Ovachlamys fulgens is only known by a few characteristics of
the shell and information on its anatomy is scant. The present

INTRODUCTION
The Helicarionoidea Bourguignat, 1877 is a diverse
group of pulmonate gastropods usually found in Africa,
Asia, and Australasia (Smith et al. 2002). Anatomical data
for many lineages in the Helicarionoidea is unknown, the
phylogenetic relationships of those lineages are poorly
understood, and the taxonomic concept fan many families
is unclear (Hyman and Ponder, 2010). The key characters
considered to discriminate families are anatomical (e.g.,
stimulator, epiphallic caecum, flagellum) which seem to
have been reduced or lost several times in many groups
(Hausdorf, 1998; Schileyko, 2002a, b; Hyman, 2007; Hyman
and Ponder, 2010).
Among the Helicarionoidea, Ovachlamys fulgens
(Gude, 1900) is known from shell characters and poor
anatomical data from reproductive system (Schileyko,
2002a, b). This species was originally described from
Loo-Choo Island, Japan. So far, this is considered the
place of origin for this species, but its distribution is
expanding rapidly throughout the tropics, most likely
unintentionally, as a neat of the horticultural trade
(Robinson and Slapcinsky, 2005). Ovachlamys fulgens
has already been recorded in some Pacific islands
(O’ahu and Hawai'i islands, in the Hawaiian Archi-
pelago and Tutuila and Olosega, in American Samoa), in
Brazil (Sao Paulo State), in Trinidad and Tobago, Costa
Rica, and Florida (Barrientos, 1998, 2000; Cowie, 2001:
Robinson and Slapcinsky, 2005; Cowie et al., 2009;
Teixeira et al., 2017). It has also been reported i
horticultural shipments from Thailand, Singapore, er
Colombia, but identification still lacks proper confir-
mation (Robinson, 2003; Robinson and Slapcinsky,
2005).
Ovachlamys fulgens is considered an important pest to
orchids and it is able to attack horticultural plants (Stange,
2004). The environmental damage caused by the in-
troduction of this exotic species is still unknown. The
main objective of this paper is to redescribe and il-
lustrate shells of type material and anatomy of recently
collected material of O. fulgens in a Brazilian national
park, in Rio de Janeiro State. With this redescription,
we hope to provide a baseline for future comparative

(Figure 1) and encompasses part of the municipali-
ties of Guapimirim, Teresépolis, Petropolis, and Magé.
PARNASO presents an altitudinal gradient ranging
from 200 to 2,263 m above sea level, with average annual
temperature of 13-23° C, and average annual pr ecipitation
reaching about 2,800 mm/year, with the highest values
between November and March (~ 360 mm/month)
(ICMBIO, 2008).
Specimens were hand-collected, mainly around the
park headquarters in Teres6polis and Guapimiri im at low
elevations (400-950 m a.s.l.) from October 2015 to
August 2017, totaling 13 field trips (2-3 days each).
Specimens were drowned in distilled water for 24h and
then preserved in 70% ethanol. Voucher specimens are
deposited at the Biological Institute of Universidade
Federal do Rio de Janeiro (IBUFRJ) according to au-
thorization provided by Chico Mendes Institute for
Biodiversity Conservation (ICMBIO).
Taxonomic identification was based on conchologi-
cal comparisons with type material and the original
description and illustration. Twenty-two undamaged
shells (2 shells of syntypes and 20 additional recently
collected shells deposited at IBUFR] 21236) were se-
lected for morphometric analysis, based on size, grading
from the smallest juvenile to the largest adult shell. Six
measurements were taken as descriptors of morpho-
logical variation (Figure 2): shell height (H), shell width
(W), height of spire (Hs), height of last whorl (H1),
height of aperture (Ha), width of aperture (Wa). Also,

the ratios of: shell height to shell width (H/W), height of
aperture to width of aperture (Ha/Wa), shell width to
width of aperture (W/Wa), shell height to height of spire
(H/Hs), and shell height to height of last whorl (H/H1).
Original data were standardized and size: adjusted using
the Burnaby (1966) method. A principal component
analysis was conducted. The curve of expected eigen-
values of a random model (Broken Stick) was use a to
select significant components. Eigenvalues for components
under This curve were considered non-significant and
then discarded (Jackson, 1993). All stetaciical pro-
cedures were performed with PAST software (Hammer
et al. 2001).
Detailed external morphology and gross anatomy were
examined in laboratory using a stereo- microscope Zeiss
Stemi SV 11 with attached camera lucida. Dissections were
performed using standard techniques, with specimens im-
mersed in fixative under the stereo-microscope. Organs of
the pallial cavity, reproductive, digestive, circulatory, excre-
tory, and nervous systems were investigate »d. Radulae and jaw
were manually extracted and prepared by immersion in
a 10% solution of sodium hypochlorite for 24h, and later
rinsed in distilled water. Nineteen specimens were dissected,
from which six had the radulae and jaw removed for imaging.

Behavior: Activity of O. fulgens in PARNASO seems
to be correlated with high humidity and all live speci-
mens were collected at night or after rainfall, always
near the trails edge, inside the park. Most specimens
were found on herbaceous vegetation (e.g. Hibiscus sp.,
Quesnelia sp., and Heliconia sp.) about 100-150 cm
above ground. Some live specimens were also found in

leaf litter, on exposed rocks, on green moss, and on
fallen trunks.
When disturbed, the specimens started the typical
behavior under stress conditions exhibited by this
species, for which it is popularly known as the jumping
snail. In such behavior, the animal retracts the head
inside the shell and turns the pedal sole, including the
caudal horn, in an abrupt and repeatedly circular movement
(usually accompanied by an increase in mucous secretion).
Most likely this activity is intended to discourage pred-
ators and often results in the snail falling from Teave 5 to
the ground.
Such behavior represents a peak of high metabolic
rates and comes at a cost. After a short period of intense
activity with usually two or three cycles of intermittent
jumps (each cycle takes about 2 seconds long) the
animal often becomes sluggish and appears exhausted.
The presence of a powerful vascular system with large
vessels certainly assists in promptly supplying the Beale
needs of energy and oxygen during the jumps, but the
small sized pallial cavity seems counterintuitive in
providing the necessary amount of oxygen. We suppose
the presence of body extensions may assist this need.
Such extensions are most often observed in marine
gastropods (e.g. Cypraeidae and Ovulidae) as projec-
tions of the foot and are associated with camouflage,
shell repair, anti-predatory activities, etc. (Vermeij,
1978). In O. fulgens the mantle edge extends forming
two thin, wide lobes, each one lies externally on each
side of the shell. These lobes presumably assume
a gas exchange function. Although further studies are
required, structures with increased surface area to
volume ratio are usually associated to exchange with

environment, mainly to gas exchange in terrestrial organ-
isms (Schmidt-Rhaesa, 2007). Since the presence of such
lobes increases the water loss by the animal, the foraging
activity is limited to high humidity periods and spots.
DISCUSSION
Shell Morphometrics: Anatomical data were absent
in the original description of Ovachlamys fulgens.
Based solely on shell attributes, no significant differ-
ences were found among between the syntypes
(photos) of O. fulgens and the voucher specimens from
PARNASO. It reinforces the conclusion that the re-
cord of this species to PARNASO is not based on
a misidentification. The most discriminative features
among the quantitative descriptors used (Table 3) are
the globose shell and the wide aperture. Those fea-
tures emerge as important conchological characteris-
tics for the taxonomy of O. fulgens.
Morphology: REPRODUCTIVE SysTEM: One remark-
able feature of O. fulgens is the uterus subdivided in two
distinct regions. The region close to the albumen gland is
reduced or even inconspicuous in young specimens, be-
coming as large as the albumen gland in adults.
Among Ariophantidae, Macrochlamys petrosa and
Sarika asamurai differ from O. fulgens by the very
convoluted hermaphroditic duct, the short genital atria,
and the presence of flagellum and stimulator. Addi-
tionally, in M. petrosa the bursa copulatrix is large and

elongated, with a long duct, and the epiphallus is of
almost equal size to that of the penis. In S. asamurai,
the bursa copulatrix is sacculiform and elongated,
with a short duct, and the epiphallus is about three to
four times longer than the penis. Among the Heli-
carionidae, Helicarion cuvieri and Nitor circumcincta
differ from O. fulgens by the presence of a flagellum.
Additionally, in H. cuvieri the bursa copulatrix is
spherical and large, with a duct as long as the bursa,
the epiphallic caecum is absent, and the epiphallus is
slender and about two times longer than the penis. In
N. circumcincta, the talon is free (not immersed in
albumen gland), the hermaphroditic duct is very
convoluted, the bursa copulatrix is elongated and
indistinct from the duct, the penis is enlarged close to
the penial sheath, and the epiphallus is of same size as
the penis, narrowing towards the flagellum.
Nervous System: The mandibular and the bucco-
pharyngeal pairs of ganglia were not previously re-
ported for the family. Both are extra to the nervous
ring and directly connected to the cerebral ganglia.
The asymmetrical structure of the nervous ring is
determined by the visceral ganglion present on the left
side only. The main differences in nervous ring between

O. fulgens and the close-related species Macrochlamys
petrosa (Hutton, 1834) (illustrated in Hyman and
Ponder, 2010: 32) are the larger thickness of the
commissures among the cerebral, pleural and pedal
ganglia in M. petrosa; and the pair of pedal ganglia,
which is partially fused in O. fulgens and separated in
M. petrosa.
Hausdorf (1998) noticed the absence of direct in-
nervation from cerebral ganglion to the penis as a non-
convergent feature and a possible synapomorphy for
Ariophantidae. To recognize the boundaries among the
families of Bicliteardloraaticlon is beyond the scope at the
present study. But it is noteworthy that the cerebral
innervation of the penis was not found in any specimens
of O. fulgens studied here, which triggers the need for
further studies and questions che validity of the
placement of O. fulgens among Helicarionoidea.

First occurrence of a novel Corbicula
(Bivalvia: Corbiculidae) Form D lineage
in the Ohio River, USA
Additional Keywords: Asian Clam, invasive species, invasion,
exotic species, non-native species
Asian Clams (Genus Corbicula) are moderately-sized
(typically <50 mm) freshwater bivalves native to the
temperate/tropical regions of Africa, southern Asia, and
eastern Australia (Britton and Morton, 1986). Corbicula
was first recorded in North America in 1924 in British
Columbia, Canada, and breached the Continental Divide
in the late 1950s (Bates, 1962: Fechtner, 1962: Stein,
1962; Counts, 1986). Since then, it has spread throughout
the United States and into South America (Lee et al.,
2005).
Literature reports vary from an invasion of only a single
Corbicula species to invasions of multiple taxa (C ounts,
1986; Hoagland, 1986; Lee et al., 2005). However,
Corbicula taxonomy is muddled and unclear, as is the
number of species that have become established in North
America (Hillis and Patton, 1982; Hoagland, 1986).
Corbicula species appear to switch reproductive strategies
and become androgenic clones when they invade new
ecosystems outside of their native range (see Lee et al.
[2005] and references therein; Hedtke et al., 2011;
Pigneur et al., 2011; 2014). This complex reproductive
behavior can include not only hermaphroditism but also
capturing eggs of other Corbicula lineages and potentially
replacing Gteiaal nuclear DNA. Separate Corbicula
lineages can differ in their nuclear 28S ribosomal geno-
type yet share identical mitochondrial mt DNA genotypes
(Lee et al., 2005; Tiemann et al., 2017). This phenomenon
contorts our under standing of traditional species concepts
and makes it difficult to detemnine if Corbicula taxa are
either separate species or individuals of distinct pheno-
types belonging to a single polymorphic species (Britton
and Morton, 1986: Lee et al., 2005).
Hillis and Patton (1982), based on electrophoretical and
morphological data, suggested two Corbicula “forms”
occur in North America. Shortly thereafter, Britton and
Morton (1986) proposed the Form morphotype classifi-
cation and recognized two Corbicula forms in North
America—Form A and Form B. Later, Lee et al. (2005)
expanded on the Form concept and reported three forms
in the New World—Forms A and B in North America and
Mis Sour Rive’

J. Tiemann et al., 2018
Form C in South America. Morphometrically, small
(<20 mm) Forms A and B specimens can be distinguished
via nacre color—Form B has a deep purple nacre whereas
Form A has a white nacre with purple highlights (Hillis
and Patton, 1982: Britton and Morton, 1986). However,
these morphological differences become unreliable on
larger specimens (Britton and Morton, 1986).
mb Midwest had long been recognized as having only
one Corbicula taxon, Corbicula fluminea (= Form A), until
recently (Cummings and Mayer, 1992). Tiemann et al.
(2017) reported hee distinct Corbicula taxa occurring in
Illinois, including one that had never been documented
in the New World. The newest taxon, referred to as
Corbicula Form D, has fine rust colored rays on the
periostracum, white nacre with purple teeth, and external
ridges that are not as pronounced as other Corbicula taxa.
Corbicula Form D was known from only a small stretch of
the Illinois River in northern Illinois, but data were lacking
as to other locations. Herein, we report on an additional
location of Corbicula Form D.
On 24 October 2017, one live individual of Corbicula
Form D (Figure 1) was collected in the Ohio River in the
Page 3]
Newburgh Pool upstream of Rockport, Indiana at river
mile 744.4 (Latitude 37.9111° N, Longitude 87.0123° W).
This specimen (Figure 2) was deposited for accession in
the Illinois Nana History Survey Mollusk Collection,
Champaign (catalogue number INHS 87523). It should
be noted that the primary objective of this field outing to
the Ohio River was to conduct unionid sampling and
Corbicula were not the primary focus. Therefore,
we cannot assess density or relative abundance of the
Corbicula here, and are only reporting presence via
incidental encounter.
Accurate species identification and reporting is critical
in monitoring the spread and, ultimately, minimizing the
ecological and economic effects of this novel Corbicula
form (Tiemann et al., 2017). We are hesitant to speculate
as to when and how Form D arrived in the Ohio River.
Because of logistical constraints (e.g., time, effort, and
monetary ORS). Corbicula from navigable rivers, like the
Ohio River, are likely to be underrepresented during field
surveys and in museum collections. If not overlooked,
Corbicula are often simply noted as “present” with no
discernable differentiation among taxa when conducting

characteristics for Corbicula Form D include fine rust colored rays on the periostracum and extemal ridges that are not as pronounced as
other Corbicula taxa.

field surveys. Natural history museums (e.g., INHS
Mollusk Collection) do have Corbicula specimens, but
these are often larger specimens, which can be unreliable
for morphotype discrimination. Regardless, Corbicula
Form D is known from a larger area than reported by
Tiemann et al. (2017). It seems likely that it has gone
unnoticed in other areas, including the Mississippi River,
which is a likely dispersal pathway een the specimen
reported by Tiemann et al. (2017) and the Ohio River
specimen we are reporting. With the aid of external
funding, additional field surveys will help determine the
validity of this claim.

Research Note
Flabellina McMurtrie, 1831: The earliest
valid Latinization?
Authorship and dating of the nudibranch genus-level
name Flabellina is dependent upon the first Latiniza-
tion of the French vernacular name ‘Les Flabellines’
introduced and used by Cuvier (1830) in the second
edition of his Le regne animal... Lemche (1964) traced
a Latinization to Voigt (1634: 124) in the German edition
of Cuvier’s work and, in due course, Flabellina Voigt, 1834
was added to the Official List of Generic Names in Zo-
ology, as Name 1721 (ICZN, 1966).
However, following Winckworth (1941) and Cowan
(1969a; 1969b), Burn (2006) attributed Flabellina to
Griffith and Pidgeon, 1833, certainly to December of that
year, but possibly as early as September (Cowan, 1971).
The online World Register of Marine Species (Caballer
et al., 2014) and Miollinrenitnes (2018) as well as the recent
taxonomic re-assessment of the family Flabellinidae
(Korshunova et al., 2017) list J.E. Gray, 1833 as the author
of Flabellina, an incorrect attribution, as Gray had no
responsibility for the English edition of Cuvier’s text (Petit
and Coan, 2008: Petit, 2012). ). J.C. Smith (1993: 188) noted
a translation into English by McMurtrie (1831) as “the
basis of most of the English translations” of Cuvier.
Reference to McMurtrie (1831) reveals that the latinized
genus name Flabellina occurs on page 343 of volume 2
(Figure | ), the title page of which is dated 1831. This year
1S eonltianeal in the publication registration statement
printed on the reverse of the title page: “Entered
according to the act of congress, in the year one thousand
eight hundred and // thirty one, by G. + C. + H.Camill, in
the clerk’s office of the southern district of // New York.”
Despite his Latinization of the vernacular name,
McMurtrie still considered Cuvier as the author of Flabellina.
But in fact that name should be credited to McMurtrie
alone as he was the first to adopt it. “Adopt”, as defined
in the glossary of the International Code of Zoological
Nomenclature means “To use an unavailable name as
GASTEROPODA NUDIBRANCHIATA. 843
SPLABELLINA, Cuv.
The tentacula of the Eolidx, with radiating rectiform branchiz,

to the Glauci, and in fact to all the Nudibranchiata, whose branchiz
are situated on the sides of the back(1).

Figure 1. McMurtrie’s (1831) Latinization, genus description
(at top of page 343) and type designation of Flabellina (at bottom
of page 343). The intervening text, containing translation of
other genera and their footnotes, has been oxaindle d.
a valid name of a taxon in a way which established it as
a new name with its own authorship and date” (ICZN,
1999: 99).
The short timeframe between publication of Cuvier
(1830) and McMurtrie’s English edition (1831) makes it
highly unlikely that an rien valid Latinization will
he. found (but see note in Acknowle dgments below).
Flabellina McMurtrie, 1831 thus appears to encompass
the earliest Latinization, author, and date. Doris affinis
Gmelin, 1791, the only species included by Cuvier (1830)
in his “Les Blabellness , was faithfully translated as the
only species in Flabellina by McMurtrie (1831). Doris
affinis Gmelin, 1791 is therefore type species, by mon-
otypy, of Flabellina McMurtrie, 1831.
Accordingly, corrections now need to be made to the
entry on ane Official List of Generic Names in Zoology,
and on the MolluscaBase/World Register of Marine
Species website.
ACKNOWLEDGMENTS
Correspondence with Charles Cowan and Richard Petit,
both regrettably deceased, concerning the Griffith and
Pidge -on translation of Cuvier (1830) was informative and
greatly appreciated. Gemma Steele, Librarian, Museums
Vitctorta. and other library staff, exceeded all expectations
by securing the McMurtrie translation, and those refer-
ences irewards my personal library. Gary Rosenberg (in
litt.) provided a reference to an earlier latinization of ‘Les
Flabellines’ (Van der Hoeven 1830), but this was un-
accompanied by a description or bibliographic reference,
and is therefore a nomen nudum not altering the in-
formation presented above. He also noted that no other
names of mollusks appear to have been introduced
in McMurtrie’s work. I am also grateful for the help-
ful comments of an anonymous reviewer. Richard
Willan graciously prepared and presented this note for
publication.

INSTRUCTIONS TO AUTHORS
The Nautilus publishes articles on all aspects of the bi-
ology, paleontology, and systematics of mollusks. Manu-
scripts describing original, unpublished research and
review articles will be considered. Brief articles, not ex-
ceeding 1000 words, will be published as Research Notes
and do not require an abstract.
Manuscripts: Each original manuscript and accompanying
illustrations should be submitted to the editor via e-mail.
Authors should follow the general recommendations of
Scientific Style and F ormat—The CSE Manual for Au-
thors, Editors, and Publishers, available from the Council
of Science Editors at http://www.scientificstyleandformat.
org/Home. html.
The first mention of a scientific name in the text should
be accompanied by the taxonomic authority, including
year. Metric, not English, units are to be used. The se-
quence of sections should be Title, Author(s) and Affili-
ations, Abstract, Additional Keywords, Introduction,
Materials and Methods, Results, Discussion, Conclusions,
Acknowledgments, Literature Cited, Tables, Figure
Captions, Figures. If the author for correspondence is not
the senior author, please indicate in a footnote. The ab-
stract should summarize in 250 words or less the scope,
main results, and conclusions of the article. Abstracts
should be followed by a list of additional keywords. All
references cited in the text must appear in the Literature
Cited section and vice-versa. Please follow a recent issue
of The Nautilus for bibliographic style, noting that journal
titles must be unabbreviated. Information on plates and
figures should be cited only if not included within the
pagination of cited work. Tables must be numbered and
each placed on a separate page. If in doubt, please follow
a recent issue of the journal for sequence of sections and
other style requirements.
Illustrations: Illustrations are rendered either at full-
page width (maximum width 17 cm) or column width
(maximum width 8.2 cm). Please take these dimensions
into consideration when preparing illustrations. Page-
width illustrations ideally should span the entire width of
printed page (17 cm). “Tall” page-width illustrations
should be avoided, square or “landscape” formats work
better. Please design plates accordingly, such that there
will be enough space left at the bottom of printed page for
plate caption. (Digital technology has made this task much
easier.)
All line drawings must be in black, clearly detailed, and
completely labeled. Abbreviation definitions must be
included in the caption. Line drawings must be high
resolution fi les at least 600 dpi (dots per inch) resolution
at actual size. Standard digital formats for line drawings
include .tif, .bmp, .psd, .eps, and .pdf.
Photographs may be submitted in black-and-white or
color, preferably in ‘RGB mode if in color. Standard digital
formats for photographs include .tif, .psd, .jpg, or .pdf.
Photographs must be high resolution files at least 300 dpi
resolution at actual (printed) size.
If more than one figure is included in an illustration,
all Hui are to be consecutively numbered eee
1 25/3, 2, NOT HigureslA, 1B, 1C,...,NOR Plate 1
Figure ih .). In ilpenetions seer more than one
figure, elke sure that blank areas between figures
should be kept to a minimum, thereby allowing for
more area for each individual figure.
Compressed (e.g., .jpg) or other low-resolution file
formats may be used to facilitate original submission and
the review process, but may not be acceptable at final
submission (see below).
Types and Voucher Specimens: Deposition of the
holotype in a recognized institutional, public collection is
a requirement for publication of articles in which new
species-level taxa are described. Deposition of paratypes
in institutional collections is strongly recommended, as is
the deposition of representative voucher specimens for all
other types of research work.
The Editorial Process: Upon receipt, all manuscripts
are assigned a number and acknowledged. The editor
reserves the right to return manuscripts that are sub-
standard or not appropriate in scope for journal. Manu-
scripts deemed appropriate for the journal will be sent for
critical review to at least two reviewers. The reviewers’
recommendations will serve as basis for rejection or
continuation of the editorial process. Reviewed manu-
scripts will be sent back to authors for consideration of the
reviewers comments. The revised version of the manu-
script may at this point be considered accepted for
publication by the journal.
Final Submission: Authors of accepted manuscripts are
required to submit a final version to the editor at jleal@
shellmuseum.org. High-resolution image files may be sent
to the editor at this stage.
Proofs: After typesetting, proofs will be sent to the author.
Author should read proofs carefully and send corrections to
the editor within 48 hours. Changes other than typesetting
errors will be charged to the author at cost.
Offprints: An order form for offprints will accompany the
proofs. Offprints will be ordered directly from the editor.
Authors with institutional, grant, or other research sup-
port will be asked to pay for page charges at the rate of $60
per page.
