ABSTRACT. A literature review of the genus, and an inventory of currently recognised species of
the genus Canalispira Jousseaume, 1875 is presented. Photographs of the animal of Canalispira
and its radula confirm its correct placement in the Cystiscidae, and morphologic comparisons are
made between western Atlantic and other worldwide species. Three new species of Canalispira
are described: C. phantasia n. sp. and C. ornata n. sp. from northern Honduras, and C. fluctuata n.
sp. from Belize and northern Honduras.
Osvaldoginella Espinosa & Ortéa, 1997 is considered as a new synonym.
INTRODUCTION
Historic review of the genus Canalispira
The confusion in the literature regarding the
taxonomic status of the genus Canalispira has, since
its inception by Jousseaume (1875), been extensive
and prolonged. This has been caused mainly by the
lack of recent references in the popular conchological
media, the misnaming of specimens in museum
collections, and the general paucity of other specimens
available for study. The group has, therefore,
remained obscure. A brief chronology of the
taxonomic history of this enigmatic genus helps to
illustrate this fact.
In his 1875 monograph, Jousseaume established the
new genus Canalispira as one of thirteen genera in the
Marginellidae, on the basis of the canaliculated suture
of the type species, C. olivellaeformis Jousseaume,
1875 (Figs 30, 31), and with great foresight drew
comparisons with the Olividae, which he had also
observed to bear this character. Subsequent
marginellid general reviews such as Redfield (1870),
Weinkauff (1878-1879) and Tryon (1882-1883)
deliberately avoided attempts at taxonomic division in
the Marginellidae. However, Weinkauff did propose a
generic classification of sorts, including Canalispira
in his ‘division 2”, which comprised those genera
lacking a ‘basal sinus’.
Early in the 20" Century, several Indian Ocean
species were described under Marginella s.1. by E. A.
Smith (1903), Preston (1906 & 1915), and Melvill
(1912). Tomlin (1917) listed alphabetically all known
Marginella and assigned them to appropriate genera.
However, even he failed to correctly place several
species in Canalispira. Laseron (1957) named thirty
new genera, including Baroginella, which was later
considered by Coovert (1995) to be a junior synonym
of Canalispira.
The gradual accumulation of data on radula and
animal characters allowed Coan (1965) to attempt a
new classification, proposing three major divisions in
the family Marginellidae: the subfamilies
Marginellinae Fleming, 1828, Cystiscinae Stimpson,
1865 and Marginelloninae Coan, 1965, placing
Canalispira in the Marginellinae.
The lack of any published information about the
anatomy of the animal, combined with a shell
morphology superficially resembling that of the
genera Volvarina and Prunum, ensured that the
historic placement of Canalispira in the Marginellidae
persisted. As recently as 1991, a new Caribbean
species, Canalispira hoffi (Moolenbeek & Faber,
1991), was described as a Prunum, with the authors
themselves admitting that it did not quite fit its
placement therein. In another case, Lipe & Sunderland
(1991) presented a new Canalispira species from
Florida, as a Volvarina species. This species still
remains undescribed, but closely resembles C. aurea
Garcia, 2006, a species from the Bahia de Campeche,
in the lower Gulf of Mexico. To compound the
problem, the genus Osvaldoginella Espinosa & Ortéa,
1997, clearly synonymous with Canalispira, was
erected for a single deep water Cuban species.
The presence of Canalispira in the fauna of southern
Africa was recognised by Kilburn (1990), who

coverage of the South African Canalispira species
was provided by Lussi & Smith (1998) in a review of
the South African Cystiscidae, but by then the
taxonomic situation had changed for the better with
the publication of the important work of Coovert &
Coovert (1995), who had divided marginelliform
gastropods into two main families: Marginellidae
Fleming, 1828 and Cystiscidae Stimpson, 1865.
Crucially they placed Canalispira in the Cystiscidae,
based upon a sketch of the animal of a Western
Australian species, and on shell morphology and
radula characters, which they had established as being
diagnostic. They made the observation that the
channelling of the suture is a species-level character in
this genus, and appealed for more study of the living
animals. They also demonstrated important ancestral
relationships between the Olividae and the
Cystiscidae, thereby confirming what Jousseaume
himself had suspected over a century earlier, and
making the genus even more interesting to study as a
special link between the two families.
species, €.
Diagnosis of Canalispira
The species assigned to Canalispira have tiny to
small-sized, robust, porcelainous shells (approx. L =
2.5- 10.0 mm). The shape is cylindrical-biconic to
narrowly ob-ovate, usually with a very weak shoulder.
The colour is commonly opaque white, creamy or
golden-tan, but some western Atlantic species,
including the ones described herein, have light to dark
brown irregular, wavy axial markings, or zig-zag
markings, some forming a tented pattern. The channel
at the suture (Figs 26-28, 30, 31) can be deep, weakly
recessed or callused over. The spire is medium to tall,
and the aperture narrow posteriorly but widening
anteriorly. The lip is thickened, especially anteriorly,
either smooth and not lirate within aperture, or
denticulate and lirate. The external varix is absent.
There is no siphonal notch, except in the west African
species Gibberula cucullata Gofas & Fernandez,
1998, discussed below. However, there is always a
deep, narrow posterior notch (Figs 23, 26, 27, 30),
even in species with no channelled suture. The
columella bears 3-6 plications and parietal lirae, and
the internal whorls are reduced in thickness by
resorption.
Geographic and Bathymetric Distribution
The genus has a worldwide distribution and has
strongholds in the Gulf of Mexico, the northern
Caribbean and the western Indian Ocean. A further
possible member of the genus has been found in the
Gulf of Guinea, in west Africa. The Indian Ocean
harbours a number of species from the east coast of
South Africa, the Gulf of Oman, and Western
Australia, and several species are present in
northeastern Australia. As yet, species of Canalispira
have not been found in most of the Pacific, including
tropical west America. Species are found from
intertidal depths to 540 m, and it is evident that, in the
western Atlantic at least, endemism is high.
Species assigned to Canalispira
Coovert & Coovert (1995) noted that there were
thirteen species of Canalispira: one from South
Australia, seven from the Indo-Pacific, three from the
western Atlantic, and two from South Africa, without
being more specific.
We consider the taxa that can be assigned to
Canalispira as follows. These are in chronological
order, with their original generic designation retained':

Habitats of Canalispira
Canalispira appear to be very widespread and diverse
in the Bay of Honduras. They can be encountered on
nearly every dive when collecting in settled muddy
rubble at depths from 2 m down to approximately 15
m. Populations have also been encountered in the
mud, amongst the roots of mangroves, where they
form an important part of the gastropod fauna. They
do not appear to favour flat sandy substrates in
shallow areas where wave action occurs.
Our first sample of Canalispira, however, were found
in dredgings performed in May 2006 from s/y Marina
Em, in 56 m, off northeastern Honduras (off Cayos
Vivarillos, dredged 56m, 16°04.9N 83°56.1W). They
were initially catalogued by us as Volvarina. All eight
shells were dead, and most were faded, and whilst
transportation of shells to this depth cannot be entirely
ruled out, it is more likely that live specimens are
found here, as it is a small location on a large, flat, off-
shore bank with little opportunity for transportation to
have taken place. The shells were of poor quality and
unsuitable for descriptive purposes. It is possible that
they are conspecific with C. fluctuata n. sp., and a
sample, labelled C. cf. C. fluctuata has therefore been
lodged as voucher material in BMNH.
Live C. ornata n. sp. was subsequently collected in the
northeastern lagoon of Guanaja, Bay Islands,
Honduras, in the muddy sand under piles of dead coral
rubble inside vital reef. From animal studies of these
specimens it became clear that the shells previously
dredged off Cayos Vivarillos were Canalispira and
not Volvarina.
In June 2006, live specimens of C. fluctuata n. sp.
were discovered at several locations in Belize, and
also in Roatän, Bay Islands, Honduras. The discovery
of the stunningly patterned C. phantasia n. sp. in a
mangrove habitat in Roatan followed a short time
later. The mangrove area is often avoided, presumably
because collecting shells here is dirty work. It is,
however, a place rich in beautiful, darkly coloured
species, and the biotope is thus worthy of description;
Along the edge of the mangroves at the waterline,
there is often a steep bank ranging from 0.2 m to 1 m
in height. At the base of this is the mud of the bay and
this gently slopes away into deeper water. There is
generally little algal coverage immediately beneath the
mangroves as this area is shaded from the sun, but the
weed and other algal growth starts outside the edge of
the leaf canopy. It is in the shaded area below the
mangrove roots and in the soft mud at the foot of the
bank where C. phantasia n. sp. are to be found. It is
interesting to note that another of our new species, C.
fluctuata n. sp., was found 300 metres from the colony
of C. phantasia n. sp. albeit in an entirely different
habitat. In addition, mangroves at Mud Hole Swash,
Roatän, (16° 21.4°N 86° 31.0°W), close to the type
locality of C. ornata n. sp., were checked but results
were negative for C. phantasia n. sp.
General anatomical observations
The anatomy of Canalispira is essentially that of a
type 4 animal (Coovert & Coovert, 1995) with a
modification in the form of greatly reduced anterior
lobes on the head, and the presence of parapodia —
‘wing-like’ lateral extensions of the foot which curl
upwards to surround the sides of the anterior half of
the shell and project forwards to form two lobes. So
extensive are these that in C. phantasia n. sp. the
yellowish foot has been observed to partially envelop
the shell in a mantle-like fashion. During movement,
the animal always holds these foot extensions as
described, and it may be that this anatomical feature is
put to use when the animal buries itself in the
substrate. Such behaviour is commonly observed in
the animals of the related family Olividae, which use
movements of their expansive foot to soften the
substrate to facilitate rapid burial.
Gofas & Fernandez (1988) recorded lateral edge
curling of the foot in Gibberula gruveli Bavay in
Dautzenberg, 1913 but this simple edge curling is not
as dramatic as that seen in Canalispira. On the other
hand, Gibberula cucullata Gofas & Fernandez, 1988
from Säo Tomé, was described as having strongly
developed ‘parapodia’ and a highly modified head.
The authors illustrated the animal (plate 2, fig. b),
which shows a remarkable anatomical resemblance to
all of our new species in that the split head has no
anterior lobes and the foot 1s translucent with small,
blurred, opaque-white spots, and completely unlike
other sympatrically occurring Gibberula species,
which are spotted in red, green, yellow and brown.
The shell of Gibberula cucullata 1s similar in size to
the tiny western Atlantic Canalispira species, and the
authors mention the deep channel at the posterior
insertion of the lip. However, unlike typical
Canalispira, the shell appears to have an anterior
notch, and strong labial denticles run the whole length
of the lip. The shell is not thick and porcelainous, is
coloured uniformly tan, lacks axial markings, and its
profile is closer to that of Gibberula than any other
Canalispira. Indeed, Coovert & Coovert (1995)
provisionally considered it to be Gibberula. Without
live animals for study to hand, we cannot make any
definitive statement as to its generic status. However,
there is a distinct possibility that this species may be
the single known species from west Africa belonging
to Canalispira.
T. MCCLEERY & A. WAKEFIELD
At the suture, an impressed or callused-over channel is
found encircling the spire of Canalispira. Tursch &
Greifeneder (2001) described, in some detail, what
appears to be an analogous structure in the Olividae
and Olivellidae and called it the ‘'filament channel
since it is occupied by a long filamentous organ. They
demonstrated that in these families the channel has no
relationship with the suture, and is found remote from
it. Our examinations of deeply channelled Indo-
Pacific Canalispira show that, unlike in the olives, it
is closely associated with the suture. It was also noted
that in all of the Atlantic species known to date, the
channel is modified by being callused over. We have
not observed a soft tissue filament in these Atlantic
Canalispira, and in our opinion the channelled suture
may simply be a product of the way the spire of the
shell is formed.
Materials and methods
Specimens were collected by the use of dredging, or
substrate suction during snorkelling and SCUBA
diving, followed by screening the sediment of large
particles, and then allowing time for the animals to
crawl out.
Digital images of the shells were made using a Kodak
PSLR/n camera mounted on an Olympus SZXI12
microscope. À radula was extracted from a single
juvenile specimen of C. ornata n. sp. The shell was
crushed and the radula was cleaned in a 10% KOH
solution before mounting in a gelatine and glycerine
medium. Images of the radula were taken using the
same camera mounted on an Olympus CX41
microscope.

Animal: Modified type 4 animal (Fig. 19). Foot
narrow, dimensionally similar to shell, rarely
extending beyond it, extending anteriorly to form
parapodia; parapodia curling up around the sides of
the anterior half of the shell, extending forward as
bilateral lobes. Foot translucent yellow, with clusters
of 4 to 8 tiny, opaque, blurred white spots, more
numerous anteriorly. Eyes black, situated centrally
within each half of the split head, distal to the base of
short, blunt tentacles which are generally held in a
vertical position. Head lobes anterior to tentacles
greatly reduced in size.
Radula unknown (not extracted).
Distribution. Found at the type locality only.
Habitat. C. phantasia n. sp. has so far been found
only in the mud at the edge of mangroves.
Remarks. The overall slightly larger size, reticulated
pattern, and specialized habitat sets this beautiful
species apart from its congeners. Other comparative
comments are presented in Table 1.
Etymology. From the Greek word phantasia: fantasy.

Distribution. This species has been found at two
locations in the Bay Islands, northern Honduras; Mud
Hole Swash. Roatan Island (16° 21.7°N 86° 31.3°W)),
A review of Canalispira
and in the Northeast lagoon, Guanaja, (16° 28.5°N
85°49.4W).
Habitat. In muddy sand, under piles of dead coral
rubble. Inside living reef, in 2 to 5 m. (At the Roatän
locality it was found in 2 m inside vital reef. At the
Guanaja locality it was also found there, but in
addition at 3 to 5 m in the centre of the lagoon. In all
these places it was found in muddy sand under piles of
dead coral rubble.)
Remarks. C. ornata n. sp. is most likely to be
confused with C. fluctuata n. sp. Their differences are
given in Table 1.
The intensity of the colour pattern is variable in this
species, as demonstrated by Figs 13-18. One of the
Roatän specimens of €. ornata n. sp. found was white,
completely devoid of pattern (Fig. 22). As this
specimen had black eyes, it cannot be considered a
true albino, and it is the only example of mutation
noticed in the genus so far.
Etymology. ornata — decorated (Latin). Named for its
intricate pattern.
DISCUSSION
The differences between our three new species are
presented in Table 1.
Regional species which require comparison with our
three new species are Canalispira minor Dall, 1927
from Georgia / northeast Florida, Prunum hoffi
Moolenbeek & Faber, 1991 from Saba, Netherlands
Antilles, Osvaldoginella gomezi Espinosa & Ortéa,
1997 from Cuba, Marginella sp. no’s 29, 80 & 83 in
Lipe (1991), and Canalispira aurea Garcia, 2006 from
Bahia de Campeche, Gulf of Mexico.
The most similar of these species is Osvaldoginella
gomezi Espinosa & Ortéa, 1997 (Cossignani, 2006:
175). Its shell is more darkly marked, is more
cylindric and is restricted to 25-55 metres off
Cienfuegos, North Havana Province, Cuba.
Prunum hoffi Moolenbeek & Faber, 1991, which
should be renamed Canalispira hoffi Moolenbeek &
Faber, 1991, is also similar to our new species. Its
profile is similar to C. fluctuata n. sp. (it has a W:L
ratio of 51% to 53%). However, it has eight labial
denticles on the lower half of the lip, whereas none of
our new species are denticulate, even when fully
mature. It has a heavily pigmented axial lined pattern
with superimposed tenting comparable to C. phantasia
n. Sp. in intensity, but the regularity of the reticulated
pattern of the latter sets it apart from the more
haphazard tenting of C. hoffi. C. hoffi is also
significantly larger at 3.7 to 3.8 mm (the lengths of the
two adult paratypes in the Dayton Museum, Ohio,
U.S.A.). C. fluctuata n. sp. and C. ornatfa n. sp. are
almost 1 mm shorter — a significant difference when
comparing such tiny shells.
T. MCCLEERY & A. WAKEFIELD
NOVAPEX 8 (1): 1-10, 10 mars 2007
C. minor Dall, 1927 is 6 mm in length, and is a
whitish, deep water species and has a taller spire than
C. ornata n. sp. C. aurea Garcia, 2006 from 77-81 m,
Bahia de Campeche, Gulf of Mexico, is also much
larger at 5.2 mm. It too lacks an axial pattern. Instead,
it is banded in orange and white.
An axial pattern of tent-like markings is present on the
shell depicted as Volvarina sp. (in Lipe & Sunderland,
1991) and sp. no. 29 (in Lipe 1991, pl. 17 no. 4 and pl.
18 no. 32). This relatively large pale orange and white
species from deep water off Florida’s Gulf coast is
allied to the species from Bahia de Campeche noted
above. Neither is otherwise similar to any of our new
species.
Looking at the western Atlantic species as a whole, it
is evident that they differ significantly from
Canalispira species from other parts of the world. The
deeply channelled suture commonly observed in Indo-
Pacific species (see C. replicata Figs 27, 28) is, in
western Atlantic species, partially or completely
callused over. Western Atlantic Canalispira are also

weakly to strongly axially patterned, and are often
orange-coloured. Indo-Pacific species are
predominantly white with no decorative pattern. For
all these reasons, the type species, which has no given
type locality, is likely to have an Indo-Pacific origin.
Another regional variation in Canalispira shell
morphology could be evident in West Africa, as seen
in the taxon Gibberula cucullata, but further research
is required on this species. However, all Canalispira
possess the characteristic unifying features of a
sharply defined, narrow, deeply channelled posterior
notch, and, where known, unique modified cystiscid
type 4 animal anatomy.
In view of the fact that we have identified three
species within a short period of time and over a
relatively small geographical area, it seems likely that
endemism and diversity is high in the western Atlantic
Canalispira, and that with further fieldwork,
particularly in the intertidal mangrove biotope, more
new species are likely to be discovered.

ABSTRACT. A new species of the genus Pandora from Senegal is described. The new species is
compared with the European and West African species from which it is separated mainly by its
smaller size and an elevation on its dorsal border.
RESUMEN. Una nueva especie del género Pandora procedente de Senegal es descrita. Se

INTRODUCTION
Few species of the genus Pandora Bruguière, 1797
are present along the Eastern Atlantic coasts. Two
species are known in the Mediterranean: Pandora
inaequivalvis (L., 1758) and P. pinna (Montagu,
1803). Recent authors consider other taxa, such as P.
margaritacea Lamarck, 1801, P. rostrata Lamarck,
1818 and P. tenuis Jeffreys, 1865 as conspecific
(Sabelli et al., 1990, Barash & Danin, 1992, Poppe &
Goto, 1993, Macedo, 1996). P. glacialis Leach, 1819
occurs in northern Europe (CLEMAM and Boss &
Merrill, 1965).
Pandora albida (Rôüding, 1798) is mentioned by some
authors (Tebble, 1966 and Nordsieck, 1969) but it is
considered by Poppe & Goto (1991) as a form of P.
inaequivalvis. That name is not mentioned in recent
works (Bouchet, Le Renard & Gofas, 2001 and
CLEMAM). Two species are mentioned in the Canary
Islands: P. pinna and P. inaequivalvis (Gômez
Rodriguez & Pérez Sänchez, 1997). In West Africa,
only P. oblonga Sowerby, 1830 is known from the
northern coast (Dautzenberg, 1910, 1912; Nicklés,
1947, 1950, 1955; Nordsieck, 1969) to Angola (Rolän
& Ryall, 1999).
A new species of Pandora was found in sediments
collected in West Africa. It is described below.

A new Pandora from West Africa
Type locality. North of the estuary of Ziguinchor,
Casamance, Senegal, dredgings at 30 m.
Description. Very thin, elongate, inequivalve shell
(Figs 1-3, 12, 13), pearly within, anteriorly rounded
and posteriorly rostrate; right valve flat, with two
posterior ribs and a narrow plate turned towards
opposite valve; left valve concave, without distinct
teeth, and with a receptacle for cardinal tooth and
posteriorly elongated ribs of right valve; ligament
internal.
Ventral margin rather uniformly curved. Umbo hardly
prominent. Dorsal margin more elongate (about three
times) from the umbo to the posterior end and short
anteriorly. Posterior margin straight or slightly
convex; anterior margin concave due to the presence
of an elevation on its tip.
Prodissoconch (Fig. 18) small, rounded ovoid, with a
diameter of 178 um.
Periostracum orange, although only fragments
subsisted (mainly in the anterior portion of the shell)
in the examined specimens.
Dimensions: Holotype 5.1 mm; all the paratypes have
about the same or smaller dimensions. Length/height
ratio between 1.92 and 2.35.
Distribution. Currently only known from the type
locality.
Biotope. The present species was collected in sandy
mud sediments, collected by dredging from 30 m in
Casamance, Senegal.
Discussion. Pandora gorii n. sp. is a very small
species, the largest specimen found measuring only
about 5 mm in length, which is vastly different from
the 25-35 mm of P. inaequivalvis, from which it is
also distinguished because the shell of the latter is
curved laterally, has a very concave posterior margin
and a narrower posterior extreme. The profile of the
different species are shown in Figs 26-29.
P. pinna is larger (20-22 mm) and more convex
laterally; the anterior and posterior margins form a
obtuse angle, whereas both are in the same line in P.
gorii n. sp. The prodissoconch is larger.
P. oblonga occurs in West Africa, from Morocco to
Angola (Figs 20-25). The shell is larger and relatively
wider than P. gorii, the anterior margin is straight, and
the prodissoconch is slightly larger. The dorsal margin
is weakly concave posteriorly and straight anteriorly,
lacking of any elevation.
Figures 1-11
The type material of P. oblonga, presumed to be in the
BMNH, was not located there (Kathie Way, pers.
comm.) and it may be supposed lost. So, the shell
figured by Sowerby (1830: pl. 1, Pandora sp. f. 10)
referred by Sowerby (1874: pl. 1) is the only original
representation of this species.
Etymology. The species is named after Sandro Gori,
Livorno, Italy.

KEY WORDS. Gastropoda, Muricidae, Antarctica, Weddell Sea, Trophon, new species.
ABSTRACT. Zrophon araios n. sp. is described from the Weddell Sea. It is compared with T
coulmanensis Smith, 1907, described from the Ross Sea and with T. veronicae Pastorino, 1999,
known from several localities from southern Chile to South Georgia.
INTRODUCTION
The Antarctic species of 7Zrophon were listed,
illustrated and commented by a few authors in the
second half of the 20" century, in particular Powell
(1951, 1957, 1958). Powell (1960) also listed a total of
26 species in his study of the Antarctic and
Subantarctic Mollusca. He was followed by
Cernohorsky (1977) who illustrated a few of them,
mainly consisting of type material housed in the
Natural History Museum, London. Cantera & Arnaud
(1985) in a more general paper devoted to the
prosobranch Mollusca from Kerguelen and Crozet
listed a few species with new localities, but without
any illustration. Hain (1990) :illustrated and
commented three species while, in the same year, Dell
(1990) published a most interesting book, more
particularly devoted to the fauna of the Ross Sea from
where he commented and illustrated 11 species.
Numanami (1996) commented and illustrated four
species and described one new subspecies. More
recently, Pastorino (2002a) described two new
trophonines from the Antarctic and illustrated a few
species. He also studied the systematic and phylogeny
of the 7Trophon species from Patagonia and Antarctica
(Pastorino, 2002b) where he listed some 33 species as
Trophon s.s. of which three were included in the
genus with reservations.
While our knowledge on Antarctic shallow water
species is rather good, the deep sea floor is poorly
investigated. À high amount of undescribed and rare
species has been collected during the three Polarstern
ANDEEP expeditions (2002 and 2005). Some of them
have been described (e.g. Engl 2004, Harasewych &
Kantor 2004, Engl 2006, Schrüdl et al. 2006, Schwabe
2006, Engl 2007), most of them will be presented in
the Atlas of Antarctic Mollusks (in prep. by the
second author) and described later. The bathymetric
range of these ANDEEP expeditions was from 1000 to
over 5000m. So Melanella guenteri Engl, 2004 (an
eyeless eulimid) has been described from a depth of
5194 m (Drake Passage).
A new Zrophon will be described here. It has been
collected by the Polarstern ANDEEP III Exp. (21.01.
— 06.04.2005). This expedition undertook not only
deep water research in the Weddell and Scotia Seas
but also linked between the DIVA expeditions
(Angola Basin) and former ANDEEP expeditions
(Weddell Sea and Drake Passage), by first macro- and
meiofauna investigation in the Cape Basin.

Distribution. Antarctica, Weddell Sea, alive in 1812-
2970 m.
Description of the holotype. Shell thin, 39.86 high x
17.94 mm width, height/width ratio 2.22, lanceolate,
broad, weakly spinose, lightly built, shoulder weakly
sloping, lightly convex. Spire high with 5+ broad,
convex, strongly shouldered teleoconch whorls, suture
impressed. Protoconch and first teleoconch whorl
eroded.
Axial sculpture consisting of low, narrow lamellae,
more strongly developed at shoulder, forming short,
open spines. Antepenultimate whorl with 10 lamellae,
penultimate and last with 9; lamellae of other whorls
eroded. Spiral sculpture low or obsolete, last whorl
with quite indistinguishable, broad P1-P6. Shoulder
smooth except axial lamellae.
Aperture large, moderately broad, ovate; columellar
lip broad, smooth, entirely adherent, anal notch
shallow, broad; outer lip smooth, thin, smooth within.
Siphonal canal long, straight, broadly open, smooth.
Dirty-white. Shell covered by remaining parts of thin,
axially striate, white, intritacalx.
Operculum light brown, ovate with apical nucleus.
Radula not examined.
Remarks. Four specimens have been dredged of
which 3 live specimens and one shell consisting of 2
fragments. One specimen (paratype ZSM Mol-
20050996) only consists of the protoconch and first
teleoconch whorl (Figs 1-2). The Protoconch is broad
with 2.15 whorls and measures 1 x 0.6 mm. The other
paratype (Figs 6-7) is subadult with strongly eroded
first whorls.
Discussion. 7. araios n. sp. resembles T.
coulmanensis Smith, 1907 (Fig. 8), described off
Coulman Island in the Ross Sea (Fig. 10) but differs in
having a larger, broader, and much more thinner shell
with a broader, more sloping shoulder, a broader
aperture, a comparatively longer siphonal canal, broad
spiral cords evident on the last whorl, and in having a
different protoconch consisting of more numerous
whorls. Dell (1990: 201) illustrated also the holotype

of T. coulmanensis and 3 other specimens that he
identified as conspecific (his figs 357-359), however
somewhat looking as T poirieria Powell, 1951 (Fig.
9). He therefore suggests that T poirieria should be
probably considered as a synonym of 7. coulmanensis.

His figure 357 is indeed closely related to the holotype
of T. poirieria and could be that species, however, his
figure 358 1s another, yet unidentified species, while
his fig. 359 is T. coulmanensis. We are of the opinion
that 7. poirieria is a different, valid species.
T. araios n. sp. could also be compared with T7.

ABSTRACT. A new species of Muricopsis from Säo Tomé, West Africa, is described and
compared with other species previously described from the same area.
INTRODUCTION
A new species of Muricopsis was collected among
material obtained while scuba diving at 30-35 m,
during a recent collecting trip to Säo Tomé islands. It
is described in the present work.
Muricopsis s. s. is represented in West Africa by
numerous species (Houart, 2005). The islands of the
Guinean Gulf seem to be one of the areas where most
species of this genus are present, with the type
locality of one of them in Annobon, two in Principe
and three in Säo Tomé.

Type locality. Lagoa Azul, Säo Tomé Island, at a
depth of 30-35 m.
Distribution. Sad Tomé Island, Lagoa Azul, and Ilha
das Cabras, 12-35 m.
Description. Shell (Figs 1-5) slender, lanceolate,
spinose, solid. Protoconch of one whorl (Figs. 6, 11-
13) white, with a single keel adapically and dense
microsculpture formed by tubercles and lines (Fig. 14)
observed under high magnification.
Teleoconch with 5-5 % whorls, rather increasing
constantly. Axial sculpture consisting of broad ribs:
first teleoconch whorl with 9, second with 8 and third
with 7; last whorl with 6 or 7 ribs. Spiral sculpture of
primary cords and numerous threads: first whorl with
visible P1-P3, second with P1-P3, starting IP and
spiral threads, third and fourth with IP, P1-P3 and
numerous threads, last whorl with IP, P1-P6, ADP and
MP, and numerous threads. P1-P4 of approximately
same strength, PS smaller, P6 narrow, low, almost
obsolete, ADP and MP small, approximately of same
strength. 2-4 spiral threads of variable strength
between primary cords. Small, acute, open spines at
intersection of axial ribs and spiral cords. Spines of P1
and P4 weakly larger. Cords more obvious on ribs,
weak or obsolete on their intervals.
Aperture ovoid elongate; columellar lip curved with 1
or 2 slight but obvious nodes, corresponding to spiral
cords; erect abapically, adherent at abapical extremity,
outer lip with 5 strong broad denticles within: ID, DI
and D2 fused, broad, D3-DS. Peristome prominent.
Siphonal canal short, narrowly open, slightly incurved
dorsally.
Background colour pink-cream:; dark brown blotches
on shoulder, between P2 and P4, near P3, P5, ADP
and MP, and on crossing points between spiral cords
and axial ribs. Aperture greyish white with yellowish
brown line on edge.
Remarks. The paucispiral protoconch in West African
Muricopsis species, denoting non-planktotrophic
larval development, is probably the reason of their
endemism, restricted to some islands or well delimited
areas. This is probably the reason also why several
Figures 1-10
populations got isolated during their adaptation to
different habitats, even within one island.
Muricopsis hernandezi n.sp. differs from all other
species living in the Säo Tomé island or having
similar shells:
M. richardbinghami Petuch, 1987 from Florida, USA,
is comparatively larger, the background colour is tan
with red bands, and the siphonal canal is much longer
and broader.
M. matildae Rolän & Fernandes, 1991, from Säo
Tome has a reddish not spinose shell with nodules and
the protoconch is constantly dark. M. rutilus (Reeve,
1846) from Ghana and M. mariangelae Rolän &
Fernandes, 1991 from Säo Tome (Figs 7, 8) have
nodulous axial ribs, the cords are also present in the
intervals and the colour is distributed in bands: dark
subsuturally, white below: another dark one in the last
whorl visible in a short portion of the suture in
previous whorls; another white one below; the base is
dark. When the lips are well developed, the aperture is
wider than in M. hernandezi; also, the external lip is
narrower and without spines.
M. delamarrei Houart, 2005, from Principe Island
(Fig. 10), has a colour pattern similar to that of the
two previous species; most of the whorls have nodules
on the crossing points of ribs and cords, and there are
spines only on the last whorl.
The existence of some shells with a very different
pattern (Fig. 9) suggests the possibility of more
species being present in Säo Tomé, in yet unexplored
habitats.
Etymology. The species is named after José Maria
Hernändez, diving and collecting companion in the
recent expedition to Säo Tomé.

Chama aspersa Reeve, 1846 (Bivalvia: Chamidae) another established
Lessepsian invader in the Mediterranean Sea

KEY WORDS. Mollusca, Bivalvia, Chamidae, Chama aspersa, distribution, Mediterranean.
ABSTRACT. The Indo-Pacific bivalve Chama aspersa Reeve, 1846 seems to have established
itself very well in the eastern Mediterranean. The species is also recorded herein from Turkish
coasts.
DISCUSSION
The species of Chama, commonly known as “jewel
boxes” have the lower valve with an anti-clockwise
growth direction. The bivalves are attached by the
lower valve to the substrate or some other object. In
the Mediterranean Sea there are four recorded species
(CLEMAM) of CHAMIDAE. Chama gryphoides, C.
circinata Monterosato, 1878 and Pseudochama
gryphina (Lamarck, 1819) are the three Mediterranean
endemic species while C. pacifica Broderip, 1834, a
Lessepsian species, is already known to have
established itself well in the eastern Mediterranean
(Bogi & Galil 1997, Ceviker 2001, Mienis 2006).
Mienis (2006) also records the presence of Chama
asperella Lamarck, 1818 and Chama aspersa Reeve,
1846, as ‘well established Lessepsian species along
the coast of Israel’. Chama aspersa Reeve, 1846 is a
very common Indo-Pacific species. Its invasion into
the Mediterranean Sea was first recorded by Mienis
(2004) from three loose upper valves found on three
different beaches along the coast of Israel. Later,
Mienis (2006) listed Chama aspersa as a well
established species along the coast of Israel. The most
striking characteristic of this species is the colour
pattern of two or three red-brown lines or bands
radiating from the umbo on the top or right valve.
We would like to record herein the presence of this
species at Mersin and Marmaris, Turkey. A few living
specimens were found by one of us (P.O.) during
several dives at these localities (June/July 2006) in
shallow waters of from 5 to 10 meters depth. At both
these localities the specimens were attached to rocks
or to bivalves such as Spondylus gaederopus
Linnaeus, 1758 (Figs 1-2). The size of the specimens
varied from 12 to 23.5mm. Chama pacifica Was also
present at these localities.
C. aspersa seems to have established itself very well
and its distribution in the Mediterranean from its first
findings has substantially increased. The species has
become rather common at the coasts of Israel (Mienis
pers. comm.). Whether these invasive species are
taking over from the established local species has still
to be evaluated.
ACKNOWLEDGEMENTS
We would like to thank H. K. Mienis from the Tel
Aviv University Israel for important literature and an
unknown referee for important comments.

Haminoea cyanomarginata Heller & Thompson, 1983 (Gastropoda:
Haminoeidae), a new invader for the Maltese Islands
Constantine MIFSUD
5, Triq ir-Rghajja, Rabat RBT 02, Malta
KEY WORDS. Mollusca, Opisthobranchia, Haminoeidae, Haminoea cyanomarginata,
Lessepsian species, distribution, Malta, Central Mediterranean.
ABSTRACT. Living specimens of the
lessepsian opisthobranch mollusc
Haminoea
cyanomarginata Heller & Thompson, 1983 were found in Maltese waters at the centre of the
Mediterranean Sea. This record extends the range of distribution of the species into the
Mediterranean.
MATERIAL AND METHODS
Several live specimens with a shell size ranging from
2 to 4mm (with mollusc 4-8mm) of Haminoea
cyanomarginata Heller & Thompson, 1983 (Fig. 1)
were found, on several separate occasions during
October and November (2006). The specimens were
found in weeds and algae brought up in fishermens”
tackle from around meadows of Posidonia oceanica
(Linnaeus) Delile, from off Id-Delli (2 specimens), off
Gnejna Bay (15 specimens) and off Fomm 1r-Rih Bay
(4 specimens), limits of Mgarr, Malta, in depths of 20-
50 m. This includes a stretch of coastline of about five
kms.
The material consisted of fresh dead leaves of P.
oceanica and some other dead algae, which at this
time (autumn) are carried by the storms and currents
from the actual meadows of the plant, either to the
beaches or to deeper water, depending on the direction
of the flow of the currents.
In each case, the material was rinsed in fresh water
and then passed through a sieve with 0.5 mm mesh.
The residue was then immediately replaced in a
container with sea water and later examined under the
microscope. Other live molluscs which were also
present, besides the specimens of Æ. cyanomarginata,
consisted of Rissoa violacea Desmarest, 1814 and
Rissoa membranacea (J. Adams, 1800) with a few
juvenile specimens of Ocinebrina aciculata (Lamarck,
1822). There were also a few specimens of Bittium
latreillii (Payraudeau, 1826) B. reticulatum (Da Costa,
1778), two specimens each of Pefalifera petalifera
(Rang, 1828) and Ocinebrina hybrida (Aradas &
Benoit, 1876) and one specimen of 7yphinellus
labiatus (Cristofori & Jan, 1832).
DISCUSSION AND CONCLUSION
The species was described by Heller & Thompson
(1993) from the Sudanese Red Sea. It is easily
distinguished from the other Mediterranean congeners
by its mantle bordered with purple or dark blue and
scattered vivid-yellow blotches all over. The soft parts
as seen through the transparent shell are bluish and
have yellow-orange blotches of various sizes. The
eyes are black and surrounded with a dark-purple
patch, forming a sort of mask.
This Indo-Pacific species is one of the recent
lessepsian immigrants entering into the Mediterranean
Sea through the Suez Canal. Although its
Mediterranean distribution has not been published
extensively in the literature (Zenetos ef al. 2004), it
had been recorded earlier by Koehler (2003) and later
by Saltik (2005) from Turkey, by Mifsud (2005) (Fig.
2) and byYokes (2005) from Greece. The species is
also listed in CLEMAM.
It seems that Haminoea cyanomarginata has found
ideal conditions of life in the Mediterranean, because
it is spreading rather rapidly. The species may have
arrived locally through ships ballast water, because the
location, being on the westerly side of the Island, is
sheltered from strong easterly winds and is therefore
an active ship bunkering site during such weather
conditions.

I would like to thank an unknown referee for
important comments and corrections on the
manuscript.

Notre Société Belge de Malacologie existe, dans sa forme actuelle (car des
sociétés similaires l'ont précédée aux 19°" et 20°" siècles), depuis 1966 et a donc
fêté ses 40 ans en cette année 2006 ! Elle a voulu célébrer cet anniversaire par une
grande manifestation dénommée "Une journée à l'Institut royal des Sciences
naturelles de Belgique" qui s'et déroulée ce samedi 25 novembre 2006.
En fait, l'équipe du Conseil d'administration préparait l'événement depuis des
mois. Ce fut donc de bon matin que tout le monde se trouva en place, avec l'aide des
conjoints et même des enfants ;-) !

Durant la matinée se déroulèrent
des visites guidées par des membres de la

aux mollusques à l'Institut royal des
Sciences naturelles de Belgique (IRSNB).
Bon nombre de naturalistes eurent ainsi
l'occasion de découvrir le monde de la
malacologie, souvent mal connu des
amateurs, par exemple, d'ornithologie ou de
botanique. Le public se montra fort
intéressé et le nombre de questions posées
montraient un réel intérêt. Pour les guides,
ce fut un moment fort agréable que de
partager leur passion avec des amateurs de
nature de tous les horizons.

NOVAPEX / Société 8(1), 10 mars 2007
Le temps de midi fut l'occasion pour les participants du matin et ceux de l'après midi (souvent, ce furent les
mêmes !) de se rencontrer et de discuter autour d'un lunch (pas trop lourd pour ne pas dormir après ;-) !).
NOVAPEX / Société 8(1), 10 mars 2007
L'après-midi fut consacrée à un cycle de conférences sur divers aspects de la malacologie et de la SBM.
N NOVAPEX / Société 8(1), 10 mars 2007
Après une introduction de bienvenue par Roland Houart, Président de
la SBM, les divers intervenants se succédèrent dans l'ordre suivant :
1) Claude Vilvens, Vice-Président de la SBM, présenta un panorama général de la faune malacologique, avec sa
diversité et ses caractéristiques générales, dans son exposé tout public "Voyage en images dans le monde des
Mollusques". Objectif bien clair : que tout le monde ait une idée globale de ce qu'est un Mollusque, des
principales classes existantes (Gastéropodes, Bivalves, Polyplacophores, Scaphopodes, Céphalopodes, .….), des
habitats qu'ils ont colonisés, des coquilles que beaucoup d'entre eux portent, etc.
2) L'exposé "Panorama de 40 ans d'activité de la SBM" permit tout d'abord à Ralph Duchamps, Président
honoraire de la SBM, de retracer l'historique de la société, avec ses débuts difficiles et ses problèmes (qui
sembleront bien familiers aux membres d'autres sociétés similaires de par le monde ;-)); il fut suivi par Roland
Houart et Claude Vilvens, qui décrivirent les activités actuelles de la SBM. En bref, il faut rappeler que la SBM
est une société scientifique d'expression francophone basée en Belgique qui vise à rassembler tout qui veut
NOVAPEX / Société 8(1), 10 mars 2007 9
approfondir l'étude des mollusques (marins, terrestres et d'eau douce) ainsi que la compréhension des divers
biotopes de ceux-ci. La SBM s'appuie à la fois sur les traditions mais aussi sur les projets d'avenir. En effet, elle
veut d'une part s'inscrire dans la lignée des sociétés savantes issues de l'engouement pour l'œuvre de Darwin et
de Linné, mais, d'autre part, elle s'intéresse à la biodiversité et à la protection des mollusques, ceci grâce aux
travaux de ses membres qui décrivent de nouvelles espèces du monde entier et de ceux qui étudient sur le terrain
les mollusques de Belgique. La SBM comporte à l'heure actuelle plus ou moins 200 membres actifs, amateurs ou
professionnels. Ses activités, basées sur le bénévolat, sont essentiellement ses réunions (en général, une toutes les
3 semaines à Bruxelles, avec une conférence sur un sujet concernant la malacologie), ses excursions (2 à 3 par
an), ses publications (Novapex régulier et des numéros spéciaux) ainsi qu'une exposition annuelle.
3) Vint ensuite celui qu'attendaient tous les malacologues
confirmés : le Dr Philippe Bouchet du Muséum national
d'Histoire naturelle de Paris, qui entretint le public d'un sujet
ô combien actuel : "Entre exploration et crise de la
biodiversité, quelle stratégie pour l'inventaire de la
faune malacologique du monde ?". Partant d'un exemple
basé sur les Coléoptères, Philippe Bouchet tira le constat
que, si l'on connaissait aujourd'hui grosso modo 2 millions
d'espèces, il en restait probablement entre 5 à 50 fois plus à
décrire. Au rythme auquel avancent actuellement les
systématiciens, il leur faudrait des centaines d'années pour
en venir à bout et, de toute manière, ils n'auraient sans doute
pas le temps de décrire toutes les espèces avant que bon
nombre d'entre elles ne disparaissent : le taux d'extinction
actuel est en effet évalué de 100 à 10000 fois plus élevé que
celui de l'extinction naturelle. La conclusion saute aux
yeux : il faut inventorier la faune plus rapidement qu'on ne
le fait pour l'instant. Comment ? Augmenter les effectifs de
systématiciens est irréaliste et impossible. Ce que prône
Philippe Bouchet : créer une chaîne d'intervenants dans le
mécanisme de cet inventaire en les spécialisant. On devrait
ainsi distinguer les récolteurs (avec leurs connaissances techniques de terrain), les trieurs-préparateurs (des
habitués au coup d'œil imparable pour distinguer les formes de vies apparentées mais différentes), les spécialistes
de la détermination proprement dits (qui décident de ce qui est nouvelle espèce ou espèce connue) et des
descripteurs (capables de rédiger une description correcte sur base des indications des spécialistes).
4) Pour clôturer, Christiane Delongueville et
Roland Scaillet, sociétaires de la Société Belge
de Malacologie, présentèrent un exposé sur "Les
espèces invasives en Méditerranée”.
Spécialistes de la malacolofaune européenne, ils
nous emmenèrent du canal de Suez vers la mer
Egée en nous montrant toute une série d'espèces
venues de Mer Rouge et en nous expliquant les
mécanismes de ces invasions.
Avant de terminer la séance académique, Mr Anthonie van
Peursen, membre du conseil d'administration de la Société
Néerlandaise de Malacologie, remit à Roland Houart un
numéro spécial et relié de BASTERIA dédié aux 90 ans de
J.G.J. Kuyper.

Comme il se doit, la journée se termina par le verre de l'amitié qui permit de prolonger les débats dans
de nombreuses conversations où se mêlaient, outre les membres des sociétés malacologiques francophone et
flamande de Belgique (merci aux amis de la BVC pour leur large présence © !), des participants Français,
Néerlandais, Allemands et même Japonais !
En conclusion, cette célébration du 40°" anniversaire de la SBM fut une réussite dont chacun eut à se féliciter !

Selon un usage maintenant bien établi, la première réunion de l'année de la Société Belge de
Malacologie a été consacrée ce 13 janvier 2007 à son Exposition : ses membres ont présenté quelques fleurons
de leur collection et les ont commentés avec sagacité et bonne humeur ©
Pour rappel, l'Exposition est destinée à tout le monde et tout le monde est donc le bienvenu. Comme
d'habitude, nous avons retrouvé quelques membres que leurs activités retiennent loin de nous, notamment notre
ami Guido Poppe et son équipe de choc ;-).
Comme lors de chaque édition, nous allons rendre compte ici des divers thèmes proposés. Et, comme
d'habitude encore, le résultat est une splendide promenade au pays des Mollusques.
Suivons donc nos habituels et sympathiques guides (ils ne prennent pas une ride ;-) !

Le genre Nassarius Duméril, 1806 en Europe
(Atlantique et Méditerranée)
Christiane DELONGUEVILLE & Roland SCAILLET
La Famille des Nassariidae comprend plusieurs genres dont un a été illustré à
2, l’occasion de l'exposition 2007. Il s’agissait de mettre en évidence les espèces du
genre Nassarius Duméril, 1806 établies sur la façade atlantique de l’Europe et en
Méditerranée. Celles-ci sont au nombre de 28 comme mentionné dans la banque de
données des mollusques marins européens du Muséum d’Histoire Naturelle de Paris
(www.somali.asso.fr/clemam/index.clemam.html).
23 des espèces illustrées étaient en provenance de notre collection, 4 autres
étaient représentées par une iconographie issue de la littérature. Nassarius robustus n’a pu être illustré par
manque de représentation récente.
Les représentants du genre Nassarius sont des espèces qui se nourrissent principalement de cadavres
dont ils identifient la présence par un sens olfactif particulièrement développé (présence d’un organe sensoriel -
l’osphradium - à la base du siphon). Ils vivent enfouis dans le sable ou dans la boue dont ils s’extraient
rapidement lorsqu'ils localisent la présence d’une charogne.
ER =:
Le tableau ci-dessous donne une indication de la distribution principale des espèces de Nassarius en
Europe :
- Quelques unes sont largement distribuées en Atlantique et/ou en Méditerranée (colonne 1).
- Certaines sont concentrées en mer d’Alboran et dans le proche Atlantique (colonne 2).
- D’autres sont confinées dans la Méditerranée orientale (colonne 3). L’une d’elles, en provenance de la
mer Rouge, a atteint la Méditerranée par le canal de Suez et se récolte aujourd’hui sur les côtes d'Egypte
(N. arcularius plicatus).
- Enfin, deux espèces sont décrites dans des zones spécifiques, il s’agit de N. tinei, dans les lacs d’eau
saumâtre aux environs de Messine (Sicile) et de N. robustus en Adriatique.
Les Nassarius sont de petits gastéropodes, en conséquence de nombreux spécimens de chaque espèce ont
été exposés. Un diaporama avec représentation photographique des espèces a défilé sur un écran d’ordinateur
durant toute la durée de l’exposition. En conclusion, cette présentation était l’occasion d’admirer, en un coup

d’œil et dans un même espace, de petites coquilles rarement mises en évidence lors d'expositions de mollusques
marins.

Pour le plaisir des yeux : Hexaplex cichoreum
Roland HOUART
a 4; . Hexaplex cichoreum (Gmelin, 1791) : une espèce polymorphe
4 04 Hexaplex cichoreum est un Muricidae, très commun, dont la taille moyenne varie entre
LP 70 et 130 mm et qui connaît un grand nombre de synonymes, notamment à cause de la
F4 morphologie très variable de la coquille.
_À Cette espèce peut se présenter sous différentes formes. Les épines d'abord: celles-ci peuvent être
quasi inexistantes, petites ou grandes, foliacées ou presque lisses, droites ou recourbées. La spire
est d'une hauteur variable. Le nombre de varices varie entre 5 et 9 sur le dernier tour, étroites ou larges, basses ou
élevées. Le canal siphonal est parfois court et large, parfois long et plus étroit.
La coquille peut également arborer différents coloris, allant du blanc intégral au brun foncé, quasi noir, en passant
par toutes les gammes de coloris: uniformes, bandes alternées blanches et brunes.
La forme déprimée, pour laquelle le nom Murex depressospinosus a été créé n'est pas non plus dénuée d'intérêt.
Il existe également une forme senestre dont je ne possède malheureusement pas d'exemplaire mais qui peut être
admirée sur divers sites internet.
L'espèce vit surtout aux Philippines mais est également présente dans d'autres régions d'Indonésie telle la
Papouasie Nouvelle-Guinée, Sumatra, et les Moluques.

Quelques mollusques terrestres "exotiques"
Claude VILVENS
Non, pas de Trochidae ;-)
Les Mollusques Terrestres sont, quand on y pense, bien plus proches de nous autres
humains que les Marins, puisque nous respirons le même air et que nous mangeons les mêmes
végétaux (enfin, nous, c'est de la salade plutôt ;-)). Si nous ne faisons souvent plus guère attention à
nos escargots de jardin (mais je vais y revenir), nous sommes par contre beaucoup plus sensibles à la
beauté des Terrestres "exotiques", donc asiatiques, africains ou américains, et, plus particulièrement
encore, ce sont les espèces tropicales qui nous attirent le plus par leurs couleurs, leur taille, leur
forme parfois si surprenante. Ont donc été présentées ici sur une carte du monde un échantillon d'espèces

On remarquera que si les familles sont citées, on est resté muet
quant aux groupes taxonomiques supérieurs (classes, sous-classes, super-
ordres, ordres, sous-ordres, infra-ordres, super-familles, tribus, etc) car,
en fait, les auteurs sont très loin d'être d'accord entre eux et tenter
d'établir un tableau systématique sur lequel tout le monde s'accorderait
semble fort délicat à l'heure actuelle.
Mais il y a autre chose .… Le lecteur attentif aura remarqué que
certaines espèces lui disent quelque chose ;-), du moins s1 11 se livre à la
malacologie de terrain en Belgique : Pomatias elegans ou Cepaea
nemoralis (j'avais bien dit qu'on y revendrait). Mais ce ne sont pas des

périodiquement avec des articles écrits hors Europe sur des espèces qui
nous sont bien connues. Donc, à méditer :

Le phénomène d'évolution dans la classe des Céphalopodes
Expo 2007 Ralph DUCHAMPS
Arpoomés wxboss (Sonde, 1786)
— L'évolution de la coquille.
L'évolution se remarque plus facilement en examinant visuellement les modifications intervenues dans
différents genres. L'exemple le plus caractéristique chez les Céphalopodes, c’est la coquille.

L'évolution basée sur une coquille relativement
compliquée, qui se présente sous la forme d’une spirale
plane involute de plusieurs tours et divisée
intérieurement par des chambres cloisonnées. Ces
cloisons ou septa sont de forme concave et laissent en
leur centre, le passage d’un siphon. Il s’agit du genre
Nautilus.
Le second genre de céphalopode cloisonné avec siphon,
c’est la Spirula dont la coquille est interne et ne
représente que 8% du volume de l’animal.
Le troisième genre est très différent dans le sens où il ne
possède pas de coquille, mais un sépion interne avec un
siphon différent par rapport aux précédents. Il s’agit de
la seiche (Sepia)
— Un problème de flottabilité.
L'évolution de la coquille va de pair avec la
résolution d’un problème de flottabilité. Celle-ci a été
longtemps considérée comme acquise, grâce à un
système d’équilibre hydrostatique. Il est basé sur le fait
d’ajouter ou d’éliminer du liquide présent dans les
chambres. C’est exact dans le genre Spirula mais pas
chez Nautilus. Pourquoi ? Parce que chez l’animal
mature, le poids total du nautile (partie molle + coquille)
est quasiment égal à celui de l’eau de mer et même
plutôt plus élevé. D’où une flottabilité légèrement
négative. Notons cependant que cette flottabilité est
positive chez les jeunes nautiles, afin de les maintenir en
profondeur. Le nautile joue sur un équilibre en régulant
le contenu du gaz et du liquide. L’eau est expulsée des
— chambres en la pompant au travers de l’ectosiphon. On
peut imaginer raisonnablement que le liquide peut circuler dans les deux sens. Pour contrôler la flottabilité 1l faut
soit augmenter, soit diminuer le poids.
— Flottabilité & locomotion.
Pour les céphalopodes à coquille cloisonnée et possédant un siphon, la flottabilité est assurée grâce à un
contrôle du liquide et du gaz contenu dans les chambres. Ce procédé se rencontre chez les nautiles, la spirule et
les seiches.
— Le Nautilus.
La coquille du nautile adulte a une fonction double : la protection et la flottabilité. Cette dernière grâce à
un appareil hydrostatique. Comparé aux deux autres genres, les chambres sont vastes, environ 20 ml, les cloisons
sont espacées et le siphon mesure au moins 30 cm ; 80% du volume des chambres est occupé par du gaz, afin de
compenser le poids propre de la coquille dans l’eau de mer. La plus grande quantité de liquide se trouve dans la
chambre la plus récente. La quantité de liquide diminue jusqu’à la 7è chambre. La variation de la flottabilité
s'effectue grâce à un système de pompe osmotique.

- La Spirula.
La coquille interne est petite et comporte plus de chambres (30 à 35) que chez le nautile. Un peu de
liquide est présent dans les trois chambres les plus récentes. De la 4è à la 20è chambre on ne décèle que du gaz.
Les chambres les plus anciennes sont remplies de liquide. Chez les jeunes individus, toutes les chambres sont
sèches, sauf la plus récente. La spirule se déplace énormément, le jour entre — 600 et 700 m, mais cette espèce
peut descendre jusqu'à — 1200 m. La nuit, l’animal remonte à un niveau vers les — 200 à 300m.
Une nouvelle chambre comporte un liquide isotonique à l’eau de mer et est sécrété dans l’espace ainsi
créé. La chambre est ensuite fermée par une cloison en forme de coupole. Lorsque la chambre nouvelle est
suffisamment solide pour résister à la pression hydrostatique, du sel en est extrait et le liquide devient fortement
hypotonique (jusqu’à 1/5è de la valeur initiale). Une bulle de gaz se forme et le liquide est progressivement
remplacé par du gaz. Lorsqu'une nouvelle chambre est totalement achevée la précédente ne contient presque
plus de liquide. Au fur et à mesure que les chambres deviennent plus anciennes, elles se remplissent à nouveau
de liquide dont l’osmolarité est beaucoup plus basse que celle de l’eau de mer. Graduellement elles deviennent
isotoniques.

( d'après Denton et al., 1967).
L’échange du liquide s’effectue par une zone perméable des cols septaux. Le liquide va vers la partie
haute du siphon, par la cuticule mince qui recouvre la face interne des chambres et des cols septaux qui fait
fonction de buvard. La position normale de nage s’effectue tête en bas. La pression du gaz dans la coquille est
inférieure à 1 atmosphère. La coquille peut résister à une pression hydrostatique d’environ 170 atm. (130-230)
— La seiche. (Sepia)
Comme pour le nautile et la spirule, la seiche comporte une partie molle et une sorte de coquille
modifiée, interne et nommée sépion. Si l’on enlève le sépion, la seiche a une densité supérieure de 4% à l’eau de
mer (1, 026). D'autre part, le sépion représente environ 9% du volume de l’animal. Pour ne pas se retrouver au
fond de la mer, la seiche doit compenser l’excès de poids. Pour une flottabilité neutre, la densité de la coquille
doit passer à 0,62. Cela signifie que le contenu de liquide dans le sépion doit être ramené à un peu moins de
30%. Pour un volume de sépion de par exemple 100ml, le volume de matière sèche est de 16ml et le poids de 36
gr. Dans cette même hypothèse, mais concernant le liquide, le volume est de 31 ml, pour un poids de 32 gr.
Enfin pour le gaz, le volume sera de 53 ml avec un poids insignifiant. Une remarque s’impose, toutes les
chambres n’ont pas un volume identique, et le contenant est également différent. La chambre la plus récente ne
NovaPEx / Société 8(1), 10 mars 2007 21
contient que du liquide (volume de 1 à 2 ml) et est isotonique au sang de l’animal et à l’eau de mer ; c.à.d. qu’ils
ont une même concentration moléculaire. La 2è chambre contient un peu de liquide et les 3è à 10è chambres
_ qui occupent la partie centrale de l’animal _ ne renferment que du gaz. Les chambres plus anciennes, sont plus
petites et sont remplies uniquement de gaz. Par contre, les chambres intermédiaires sont remplies à la fois de gaz
et de liquide. Elles sont situées dans la partie ventrale de la seiche, en contact avec l’épithélium siphonculaire.

Les parois entre chambres sont totalement étanches. Quand la construction d’une chambre est achevée,
le liquide en est extrait au travers de la membrane siphonculaire, et ce à partir du moment où cette chambre est
capable de supporter la pression hydrostatique. Le gaz entre lentement par diffusion dans l’espace vide. Dans la
chambre la plus récente la pression du gaz est de 0,2 atm. La valeur moyenne étant de 0,8 atm. celle-ci n’est
atteinte qu’à partir de la 9è chambre (donc très inférieure à 1 atm). Il faut plus d’un mois pour qu’un équilibre
s’installe entre l’azote présent dans le tissu vivant et celui contenu dans les chambres.
Lorsque la pression hydrostatique est plus importante que la pression osmotique, l’eau de mer pénètre
dans la chambre et comprime le gaz présent. Après extraction des solutés du liquide caméral, principalement du
sodium et du chlorure, celui-ci devient hypotonique par rapport au sang (concentration en dessous de celle du
sang). L’eau s’écoule de la chambre vers le siphon, puis dans le sang, et est éventuellement éliminée par les
reins. Le gradient osmotique entre le sang et le liquide caméral peut jusqu’à un certain point équilibrer 5 des 7
atm. d’une seiche vivant à — 70 m. Plus l’animal vit à une grande profondeur, plus il subit une pression plus
importante et plus le gradient est hypotonique pour le liquide des chambres. Toutefois si une seiche va à une
profondeur inférieure à — 240 m, la pression hydrostatique est suffisamment forte que pour faire pénétrer le
liquide dans les chambres, même si leur osmolarité a atteint la valeur zéro. Le gradient osmotique ne peut plus
contrebalancer la force hydrostatique.
— L’argonaute.
On pourrait s’étonner de ne pas voir figurer l’argonaute parmi les trois genres traités ci - avant, mais ce
céphalopode ne possède pas de coquille, seule la femelle occupe une nacelle qui outre l’animal, abrite également
les œufs. Les coquilles sont secrétées par le manteau et composées principalement par de l’aragonite, tandis que
la nacelle de l’argonaute est composée de calcite et secrétée par une paire de bras.
29 NOVAPEX / Société 8(1), 10 mars 2007
Les autres systèmes de flottabilité.
En dehors des trois genres récents cités c1 avant, un grand nombre de familles Argonautidæ, Teuthoidæ
et certains octopodes pélagiques, utilisent un autre système pour diminuer la densité de leur corps et jouir d’une
flottabilité neutre. Par exemple l'intégration dans le corps de liquide fait de substances légères. Le système le
plus répandu consiste à intégrer dans le coelome ou dans les tissus des ions légers. Notamment un liquide riche
en ammonium. L'’ammoniaque a également été détectée dans différents tissus. Par exemple, les Cranchiidæ
élargissent leurs sacs coelomiques de manière à occuper environ les 2/3 du volume de l’animal, ce qui les rends
isotoniques à l’eau de mer. Mais le liquide plus acide et les ions de sodium sont remplacés par des ions
d'ammonium. Certains octopodes possèdent des muscles peu développés, mais ont une énorme quantité de
matière gélatineuse, où les ions sulphate de l’eau de mer sont remplacés par des ions chlorure, ce qui engendre
une flottabilité neutre. L’Ocythoe qui est un octopode épipélagique, possède au dessus du jabot une chambre
remplie de gaz comparable à la vessie natatoire des poissons. D’autres bénéficient de lipides légers ou d’huile
accumulés dans la glande digestive. La présence de gaz et d'ions légers accumulés dans le corps sont l’apanage
des céphalopodes nageurs peu rapides. La solution apportée pour les nageurs rapides sont leurs forces
hydrodynamiques ou forces d’ascensions.

vivent, allant de la vase compacte à la

développé une coquille de forme allongée,

hypoplax ; ajoutons des condyles, callums,
siphonoplax, chondrophores, etc.
Renonçons à d’autres détails, mais
remarquons que, dans nos collections,
forcément, les pièces additives manquent
souvent.
Pour creuser, ils utilisent divers
procédés, soit une action de râpe en
pivotant, soit des sécrétions acides.
Pour leur classification, la
présence ou non de ces divers éléments
entre en ligne de compte mais aussi leur
capacité à creuser plus ou moins
profondément.
NOVAPEX / Société 8(1), 10 mars 2007
Pour essayer de visualiser et comprendre tous ces détails, avec un peu de courage, on peut consulter, par
exemple, le « Treatise on Invertebrate Paleontology. Mollusca 6. Bivalvia. Moore, 1969 » pas tout neuf, mais
très instructif et détaillé.
Pour les néophytes, remarquons une ressemblance avec certains Petricola comme justement, Petricola
pholadiformis, que l’on trouve échoué sur nos plages ; ce sont des Veneroidea, ils n’ont pas de pièces additives
et ils ne ressemblent pas tous aux Pholades.
Pour notre exposition, je me suis limitée à de beaux exemplaires bien connus parmi les Pholadinae,
quelques rares exemples d’autres sous-familles et des Petricola pour comparaison.
Et en prime, un tableau peint par l'auteur qui a des talents d'artistes (NDLR).

La famille des Unionidae : une sélection …
Etienne MEULEMAN
Les Unionidae ont une répartition mondiale et sont très diversifiées dans l’est et la partie
centrale du nord de l’ Amérique. La coquille est de forme très variable, la région antérieure
beaucoup plus courte que la région postérieure. La sculpture des sommets est très variée, parfois
peu développée, la charnière est de forme variable, parfois rudimentaire. La famille des
Unionidae se divise en plusieurs sous-familles, tribus, et une nombre important de genres. Rien
qu’en Amérique du Nord, on dénombre près de 300 espèces réparties en 43 genres, six tribus et
deux sous-familles.

Pterotrachea coronata Forskäl, 1775
Sophie VALTAT
R\ Pterotrachea coronata Forskäl, 1775 est un
gastéropode pélagique de la superfamille des
Pterotracheoidea Rafinesque, 1814, qu'on nomme
également les hétéropodes.
Les hétéropodes comprennent trois familles :
+ les Atlantidae Rang, 1829 qui possèdent une coquille
spiralée à l'état adulte, on les considère comme les moins ee
évolués des hétéropodes,
* les Carinariidae Blainville, 1818 possèdent également une
coquille, mais trop petite pour que le corps de l'animal puisse
se rétracter complètement à l'intérieur,
* les Pterotracheidae Rafinesque, 1814, qui ne possèdent plus
de coquille qu'à l'état larvaire.
A défaut de coquille, c'est une video de Prerotrachea
coronata Forskäl, 1775 prise par Walter Jung sur les côtes
espagnoles à faible profondeur qui nous a permis d'admirer
cet "étonnant éléphant de mer”.

Quelques Spondyles
Jacques et Rita SENDERS
Cette famille de
bivalves est appréciée des
collectionneurs, à l'instar des
Pectinidae. Elle comporte
une soixantaine d'espèces
recensées.
Les spondyles
nécessitent très souvent un nettoyage délicat des
valves et
des nombreuses épines qui les couvrent. Ce sont les
plongeurs, avec bouteilles d'air comprimé (Scuba),
qui ramènent les plus beaux exemplaires. Les
spondyles les plus facilement accessibles se récoltent
sur fond meuble: sable et boue. Les valves
inférieures sont alors couvertes de voiles qui
remplacent les épines et qui ancrent la coquille sur le ;
fond marin. Il est évident qu'il est difficile d'obtenir un spécimen parfait à HE de drasae ou de filets genre
"tangle nets”.
La couleur joue également un rôle important dans la rareté et donc le prix de certains spécimens.
Le Spondylus americanus est recherché pour son abondance, la grandeur de ses valves, la variété de ses
couleurs et la fait que plusieurs spécimens peuvent former un ensemble magnifique. Nous avons conservé
quelques semaines un amas ("cluster") de 27 belles coquilles que nous avons dû abandonner par manque d'une
place assez grande dans nos vitrines.
Un autre spondyle très recherché: le Spondylus lingaefelis dont les très nombreuses épines lui ont
donné le nom. Heureusement pour les amateurs de chats, la langue de leurs petits amis à quatre pattes est
autrement douce que le contact du coquillage. Là aussi la couleur joue un grand rôle dans la rareté de cette
espèce: le jaune est le plus recherché, viennent ensuite les blancs et les brun-orange. Les coquilles originaires des
Philippines sont pratiquement dépourvues d'épines tandis que les plus belles proviennent d'Hawaïi et des îles
Salomons.

Heureusement une bonne loupe, de bons dessins et de bonnes photos étaient à disposition. La plus
grande coquille faisant quand même 2,4 mm ! Et la vitrine 30 x 40 mm !

L'écho des réunions
Annie LANGLEIT
Réunion du 16 décembre 2006 (AL) = Sophie Valtat : Les Mollusques pélagiques, un
panorama général.
Sophie Valtat nous a appris que de drôles de mollusques, avec ou sans coquilles, se laissaient flotter,
dolce farniente, à la surface des
océans en faisant des bulles ou
entre deux eaux à profondeurs
diverses, au gré des courants
marins.
De tout petits mais aussi de tout
grands, parfois translucides,
fantomatiques.
Ces organismes sont peu
connus des amateurs sauf les si
jolies Janthina et les délicates
Carinaria ; nous avons donc
découvert pas mal de choses.
Quant aux noms de ces
curieuses bestioles, c’est à pleurer.
Aussi Sophie, prévoyante, a
commencé par la consolation, elle
nous a offert un petit verre de
Muscat et un super gâteau de Noël,
spécialité maison.
Donc je ne vous explique pas les Caenogastropoda, Ptenoglossa, Heterobranchia, Thecosomata,
Gymnosomata, Nudipleura et autres noms d’oiseaux, pardon, de Mollusques. Sachez que ce domaine est très
vaste et complexe et mériterait qu’on s’y intéresse plus largement.

Quelques nouvelles publications
Roland HOUART & Etienne MEULEMAN
1. Quelques livres
Marine & Brackish water Gastropoda of Russia and
adjacent countries :
An illustrated catalogue
par Yu. I. Kantor et A.V. Sysoev
Format: 210 x 295 mm, couverture carton rigide.
pp. 1-371, 140 planches couleur. Editeur: KMK Scientific Press Ltd, Moscou, 2006
Prix: 85 € + frais d'envoi.
Ce livre constitue la première partie d'une série consacrée aux
mollusques de Russie et des régions avoisinantes. Il contient les
données et les illustrations de 1240 espèces, regroupées dans 350
Mopc Rue genres et 110 familles d'espèces marines et d'eau saumâtre,
H CONOHOBATOBOZAHEIE peuplant la Russie et les régions de l'ancienne URSS. Le texte
GpHXOHOTHE MOXIHOCKH est bilingue, sur deux colonnes, russe/anglais.
Après une courte introduction discutant des diverses études et
publications sur la biodiversité, les auteurs se focalisent sur les
études récentes ayant mis la faune malacologique russe en
exergue, notamment le catalogue des mollusques de Russie, sur
lequel cette série est basée. D'autres petits chapitres tels des
commentaires sur les illustrations, le matériel type, le système de
classification utilisé pour ce livre et les remerciements, précèdent
la liste des abréviations, toujours utile et parfois oubliée dans
certains ouvrages. Un tableau des taxa supérieurs utilisés dans ce
premier volume clôture le texte introductif.
La partie systématique reprend le genre actuel, le nom de
l'espèce, l'auteur, la date de description, la synonymie, la localité
type, le matériel type, la distribution géographique et quelques
remarques sur la taxonomie, la synonymie et la distribution. La
partie texte se termine par 35 pages de bibliographie contenant
790 références et par l'index taxonomique.
Les coquilles sont représentées en couleur, sur fond blanc, très
souvent illustrées à l'aide de spécimens appartenant au matériel type (holotypes, paratypes, lectotypes, syntypes),
avec mention de la taille et quelquefois de la localité, lorsqu'il s'agit de matériel provenant d'autres collections.
Certaines petites espèces comme quelques Hydrobiidae sont représentées par des dessins.
Les photos sont excellentes et les espèces très facilement identifiables grâce à la très bonne qualité et à la taille
des reproductions.
Il s'agit incontestablement d'un livre qui sera vraiment le bienvenu dans toutes les bibliothèques malacologiques.
Le peu de littérature actuelle existant sur cette région, le nombre croissant de nouvelles espèces découvertes et
décrites durant les dernières décennies et le désir bien compréhensible pour l'amateur ou le professionnel de
vouloir identifier correctement les espèces devrait valoir un accueil très favorable à ce nouveau venu.
C'est un ouvrage à acquérir d'urgence chez votre libraire favori.

Morceaux choisis
Claude VILVENS
Voici quelques articles concernant les Mollusques et la biodiversité parues ces derniers mois dans
diverses revues. Une copie disponible à la bibliothèque de la SBM.
1. Natura Mosana : vol.59, n°1 — janvier-mars 2006 - Sur la présence du gastéropode
Vertigo moulinsiana en Lorraine belge, avec quelques notes de malacologie et
d'entomologie hivernales dans les marais de al Haute Semois (pp.5-25)
Natura Mosana est un bulletin publié avec l'aide du Ministère de la Région Wallonne (Division de la
Nature et des Forêts) et rassemble diverses sociétés naturalistes des provinces Wallonnes. Ce numéro présente un
intéressant article (signé J-Y Baugnée, G. San Martin & P. Verté) sur des découvertes de terrain en Lorraine plus
particulièrement sur le plateau du Landbruch : Vertigo moulinsiana y a été trouvé en rassemblement hivernal,
notamment sur des feuilles de Carex (voir photo extraite de l'article). Plus généralement, l'article repasse en
revue les 7 espèces belges de Vertigo, avec des données sur leur distribution. Voilà qui remet en lumière ces
Terrestres trop souvent négligés de par leur petite taille et leur camouflage dans les litières : belle initiative !
Dommage cependant que toutes les espèces ne soient pas illustrées (on nous renvoie à Adam).
2. BBC-Wildlife : vol.24, n°11- octobre 2006 - Strange but
true .… Snaïl mail
La revue naturaliste britannique rappelle à notre bon souvenir un
mollusque des "hydrothermal vents", donc d'eau profonde (Océan Indien) qui
présente la particularité de posséder sur son pied des écailles métalliques (en
fait, faites de sulphide de fer). Ce qui conduit évidemment à l'image d'un
ecargot en armure ;-) ! Il semblerait que cette espèce n'ait pas encore de nom.

carnivorous slugs. :
La même revue naturaliste, dans son numéro de
décembre, nous ramène vers les Opisthostoma, ces
Terrestres aux formes que l'on peut presque qualifier
d'"extravagantes" — la raison étant probablement la défense
contre les prédateurs. Les espèces dont il est question ici
vivent à Bornéo — il est question ici d'une étude réalisée sur
les rives de la rivière Kinabatangan. Autre point
remarquable : on trouve une espèce différente pratiquement
à chaque colline, ce qui rend évidemment ces organismes
très exposés à tout changement d'environnement . voilà
qui rappelle, par exemple, certains Terrestres de
Madagascar.

Le dictionnaire de malacologie
LS La SBM entend donner 101, à moyen terme, un outil qui permettra à tous de trouver, en français, la défiration d'un
terme de malacologie ou quelques précisions sur un malacologue célèbre. Cette partie de notre site sera probablement toujours
en cours d'évoluhon. Mais ne sera-ce pas là aussi son intérêt ?
Ce “dictionnaire de malacologie" sera un travail collectif et de longue haleine. Il ne faut donc pas s'étonner de ne pas
trouver pour l'instant tous les termes ou tous les malacologues | Notre dichonnaire s'articule selon deux axes :
+ La définition des termes de malacologe
+ Les malacologues célèbres

Comme d’habitude, respectez la nature. Nous avons parfois l’impression que, lors des grandes marées, la plage ou la
grève ont subi un bombardement, tant les trous occasionnés par les pêcheurs à pied sont nombreux. Remettez les
pierres en place, ne prélevez pas de petits spécimens et collectez sans excès. Surtout, observez et photographiez.
Renseignez-vous sur l’heure et la hauteur exacte de la marée basse de l’endroit où vous vous trouvez. Bonne marée !

KEY WORDS. Triphoridae, type material, Reunion Island.
ABSTRACT. Fourteen species of Triphoridae have been described from Reunion. The type
material is examined and illustrated, and the status of the nominal species is revised. Six neotypes
are designated. All species are illustrated by SEM and /or colour figures.
RESUME. Quatorze espèces de Triphoridae ont été décrites de la Réunion. Le matériel type est
examiné et illustré et le statut de ces espèces nominales est révisé. Six néotypes sont désignés. Des
illustrations en microscopie électronique à balayage et/ou des illustrations couleurs sont données
pour chaque espèce.
INTRODUCTION
To my knowledge, only two authors, Deshayes (1863)
and Jousseaume (1884 and 1896) have described new
species of Triphoridae from Reunion. In the present
paper I evaluate them, fix primary types, and provide
modern, high quality illustrations for each of these
species.
The "Catalogue des mollusques de l’île de la
Réunion", by Deshayes, is part of a book by L.
Maillard, "Notes sur l’Ile de la Réunion". In this work,
Deshayes described the material gathered on Reunion
and entrusted to him by Maillard. Deshayes
recognized 560 species, of which 12 were species of
Triphoridae. He attributed two of them to taxa already
known, namely Triphora sculpta (Hinds, 1842), and
Triphora monilifer (Hinds, 1842), and described the
other 10 as new species. Deshayes's collection was
deposited in the "Ecole des Mines" in Paris, where he
was a professor. After a phase of curatorial neglect in
the 1960-1970s, it was decided that the mollusc
collection of that institution would be incorporated
with the paleontological collection of the University
of Lyon, with the types of recent species to be
deposited in MNHN. The "Ecole des Mines"
collection was thus searched by P. Bouchet in 1978
for such types, before the actual transfer of the rest of
the material to Lyon, and I myself searched the
collection in Lyon to double check for missing types.
Besides Deshayes' types, MNHN holds material
labelled "ex. d’auteur ('author’s specimens"), coll.
Vignal, Com. Eudel, 1941, St. Pierre" [Reunion
Island], whose status has to be discussed. Emile
Eudel was a merchant mariner. He gathered shells
from around the world, and visited St Pierre, on
Reunion, where his brother lived. Eudel’s collection
was sold in Paris in 1893. Sowerby purchased part of
it, and Vignal purchased another part, mainly
Cerithioidea. The collection of Vignal was acquired
by MNHN in 1941. In the foreword of his work,
Deshayes (1863) thanked Eudel for sending him,
preserved in alcohol, shell-less molluscs not present
in Maillard’s collection. Eudel’s collection also
contains one lot labelled "Cerithiopsis blandi
Deshayes (in litt.)". It is thus clear that Eudel was in
touch with Deshayes, but we do not know whether the
indication "Ex. d’auteur" implies that specimens were
sent by Deshayes to Eudel as a gift, or whether
Deshayes identified for Eudel material in his
collection. As Deshayes did not explicitly cited
Eudel’s specimens in his work, I do not regard these
specimens as part of the original type lot.
The illustrations in Deshayes’ paper (1863) are of
small size, and lack precision, and this is why it 1s
necessary to revise the status of the nominal species
based on the type material. However, Deshayes’ types
consist mainly of beach specimens, often broken and
incomplete, especially lacking protoconchs. In several
lots, the specimens labelled as "syntypes" clearly do
not match the original description. Furthermore, some
types could not be found and must be considered lost.
Jousseaume described many species of Triphoridae
from the Red Sea and from New Caledonia, and only
4 are from Reunion (designated in Jousseaume as
"Bourbon", an earlier name for the island). Two
species were described in his «Monographie des
Triphoridae » (Jousseaume 1884), and two others in a
publication with a misleading title, « Triphoridae de la
Mer Rouge recueillis et décrits par le Dr.
Jousseaume » (Jousseaume 1896). By contrast to
Deshayes' types, the types of Jousseaume are all
present in MNHN, and are in rather good condition.

Triphoridae of Reunion Island
SYSTEMATICS
Family: FRIPHORIDAE Gray, 1847.
Genus Triphora Blainville, 1828.
Type Triphora
1828 (by original designation).
Indian Ocean.
Blainville,
Recent, Mauritius,
species: gemmalum
Triphora adamsi (Deshayes, 1863).
Figs 1-3, 45
1863:
Triphoris adamsi Deshayes 100,
number 322, pl. XI, figs 23-24.
species
Type locality. Reunion Isl. without any other data.
Type material. There is a single specimen labelled as
a syntype in MNHN 1579 (Fig 45). This specimen is
in good state, has a protoconch of 5 whorls bearing 2
fine spiral cords, crossed by close-set fine axial riblets,
and a rounded apex. The teleoconch whorls bear 3
beaded spiral cords, the middle one weaker on earlier
whorls, but well developed on the last 3 whorls. The
shell is glossy, pale brown, the earlier whorls whitish,
the protoconch is brown, the last whorl pale brown.
Comments. The species is easily recognizable, and is
very common on Reunion, where I have found empty
shells in sand at depths ranging from 5 to 40 m. The
voucher specimen 1llustrated by SEM (Figs 1-3), 4
mm, from cape La Houssaye, Saint Paul, in hand-
dredged sand at 20m, is now in MNHN.
In my opinion 7riphora adamsi (Deshayes, 1863) is
quite a valid species.
Triphora angustissima (Deshayes, 1863).
Figs 4-6, 46
Triphoris angustissimus Deshayes 1863: 104, species
number 328, pl. XII, figs 1-2.
Type locality. Reunion, cape La Houssaye, Saint
Paul, depht 10-12 m. Determined by locality of
neotype.
Figures 1-12
1-3. Triphora adamsi (Deshayes , 1863)
Type material. No original type material could be
detected in MNHN, nor in Lyon. A neotype is here
designated, MNHN 9488 (Figs 4-6, 46).
Comments. The original description refers to an
elongate and narrow shell, with 2 unequal spiral rows
of beads, the abapical row with larger beads, and with
a Wide and Canaliculated suture, size 4 x 0.75 mm.
This valid species is readily recognizable from
Deshayes” description and figure, and is fairly
common on Reunion where I collected over 200
specimens, dead in sand (Fig. 46).
Description of the neotype. Shell narrowly conical,
with very slightly convex edges, base not constricted.
Protoconch poorly distinct from teleoconch, consisting
of 2 whorls with a small rounded apex ; each whorl
bearing 2 beaded spiral cords, the lower with strong
beads, the upper one with very weak beads, the beads
on protoconch being more numerous and more closely
set than on teleoconch (18 beads per whorl).
Teleoconch comprising 13 whorls, bearing 2 beaded
spiral cords, the lower being stronger, 14 beads per
whorl ; suture moderately impressed. Aperture wide
quadrangulate, posterior canal short directed
downward. Colour greyish cream, becoming
whitish towards summit. Size 5.3 x 1 mm. Dead on
sand bottom near coral reefs, cape La Houssaye, Saint
Paul, depht 10-12 m.
Triphora crenulata ( Deshayes, 1863).

Type material. A single juvenile specimen, labelled
syntype, is in MNHN 0721. It is somewhat faded, but
has an intact protoconch, and measures 4.8 mm. (Fig.

Triphoridae of Reunion Island
Comments. Deshayes described a 9 mm x 2.5 mm
shell. Specimens that match the original description
and the syntype are not infrequently found in Reunion,
but the species is not common. À juvenile specimen of
the same size as the type 1s selected and illustrated by
SEM (Figs 7-9). Figure 47 is an adult specimen, 9
mm.
This nominal species, remarkable because of its
coloured pattern, may be a synonym of 7riphora (Ino)
elegans (Hinds, 1842) p.18, Plate VII fig 11, (
Straits of Malacca, in mud 20 fathoms). But this
remains uncertain, Hinds’description being short and
the figure small.
Marshall (1983: 51, figs 21G-I) placed this species in
genus Euthymella.
Triphora distincta ( Deshayes, 1863).
Figs 10-12, 38, 48
1863:
Triphoris distinctus Deshayes 103, species
number 326, pl. XI, figs 30-31.
Type locality. Reunion, cape La Houssaye, Saint
Paul, depht 10 m. Determined by locality of neotype.
Type material. One lot in MNHN 0719 labelled
"syntypes" consists of 3 specimens glued to a
cardboard (Fig 38). These worn specimens, lacking
their protoconch, are brown except the first three
whorls that are whitish, and have 2 beaded spiral cords
of 18-20 beads per whorl, the upper row somewhat
paler. These specimens do not match the description
and illustration of 7riphora distincta, which has 3
beaded cords per whorl. A substitution of labels may
have occurred, and I do not regard these specimens as
syntypes. Furthermore, until now no specimen with
the characters of these supposed syntypes has been
found in Reunion. Therefore a neotype is here
designated, MNHN 9489 (Figs 10-12, 48).
Comments. Deshayes' description is of a conical and
slightly convex shell, comprising 13 whorls, each
Figures 13-24
13-15. Triphora formosa (Deshayes, 1863)
bearing 3 unequal spiral rows of beads, the middle one
weaker; suture canaliculated; colour dark brown,
dimensions 5 mm x nearly 2 mm. The illustration
shows a conical, slightly fusiform shell, with 3 beaded
spiral cords, subequal on last whorl, the middle cord
weak on adapical whorls; 9 beads per half whorl.
Shells corresponding to that description are common
on Reunion. The 5 specimens from the MNHN lot
labelled "Ex. d’auteur, Coll. Vignal, 1941" (not type
material) are similar.
Triphora distincta Deshayes, 1863 is a valid species.
Description of the neotype. Shell fusiform, base
slightly constricted. Protoconch quite distinct,
consisting Of 4 whorls, bearing a single spiral carina
crossed by numerous closely-set axial riblets, and a
small rounded smooth apex. Teleoconch comprising
12.5 whorls, the earlier ones bearing 2 spiral beaded
cords, a third median weak cord appearing at the fifth
whorl, becoming equal to others on the 3 last whorls.
24-25 beads per whorl. Suture moderatly impressed.
Aperture quadrangular, posterior canal short and
recurved. Colour brown, the 4 earlier whorls whitish,
protoconch pale brown. Size 6.3 x 1.7mm. Dead in
sand near coral reef, cape La Houssaye, Saint Paul, at
the depht of 10 m.

Type material. No original type material found in
MNEHN, nor in Lyon. A neotype, MNHN 9487, is here
designated (Figs 13-15, 49).

Triphoridae of Reunion Island
Comments. Deshayes' description is of an elongate
and pointed shell with a deep canaliculated suture, 2
spiral rows of beads that are not axially aligned but
disposed in alternate rows, colour pale pinkish violet
with paler beads; aperture small and circular, terminal
canal long and recurved posteriorly; dimensions 6
mm height x a little less than 1.75 mm diameter. The
original illustration shows a high, slender, and pointed
shell with 2 beaded spiral cords per teleoconch whorl,
and 7 beads per half whorl.
Triphorid specimens matching Deshayes original
description and neotype, except for colour pattern, are
regularly found in Reunion, though uncommon; some
of them with a violaceous background and a yellowish
abapical cord (Fig. 50), these colours fading with
time, while other specimens are plain light brown.
These probably only represent colour variations, as
they all have a similar protoconch, and a completely
closed anal canal.
Description of the neotype. Fusiform shell, conical,
tapering to a sharp apex, base slightly constricted.
Protoconch hardly distinct from teleoconch, consisting
in 2 whorls bearing a single strong beaded spiral cord
crossed by axial riblets, and a smooth apex.
Teleoconch of 12 whorls, 2 beaded spiral cords per
whorl, the beads in alternate rows. Suture deep,
canaliculated. Aperture circular, anterior canal long
and recurved, and a short and small third canal on the
left side ot outer lip. Colour pale violet with paler
beads. Size 6.2 x 1.8 mm. Dead in sand near coral
caves, 10-12 m, cape La Houssaye, Saint Paul.
Triphora formosa (Deshayes, 1863), is a valid species.
Triphora hindsi (Deshayes, 1863).

25-27. Triphora reevei (Deshayes, 1863)
Type locality. Reunion, cape La Houssaye, Saint
Paul, depht 10m. Determined by locality of neotype.
Type material. One lot MNHN 0709 labelled
"syntypes" comprises 5 specimens originally glued to
cardboard, but the best of which (Fig. 39) was
detached, presumably for study. AI are white and
very worn. Only the detached specimen has the two
last whorls of the protoconch left, on which two fine
spiral cords crossed by fine axial riblets remain
conspicuous. The teleoconch whorls of the 5
specimens are only ornamented with 2 beaded spiral
cords. These specimens do not match the description
and illustration of 7riphora hindsi in Deshayes,
which has 3 beaded spiral cords on the last whorls.
Here also, a substitution of labels may have happened.
These supposed "syntypes" belong to a species that is
common in Reunion.
A neotype is here designated, MNHN 9490 (Figs 16-
19,510)
Comments. Deshayes described an elongate and
narrow shell, with 3 beaded spiral cords on teleoconch
whorls, the middle one being slightly weaker, with a
narrow suture hardly distinguished from the space
between cords. He described it as pale brown in
colour, with whitish beads, and 6 x 1.25 mm in size.
Deshayes’ figure shows 3 beaded spiral cords on
teleoconch whorls, subequal on the 3 last whorls, but
with the middle one weaker on the 2 preceding
whorls, while there are only 2 spiral cords on the 5
earlier whorls; there are 9 beads per half whorl.
Another species, common in Reunion, matches
exactly Deshayes’description and figure, and the
specimens of the Vignal collection in MNHN labelled
T. hindsi Deshayes, (not type material) and is then the
true 7riphora hindsi.

Description of the neotype. Shell conical, shghtly
constricted at base. Protoconch consisting of 4 whorls
tapering to a smooth hemispherical apex, each whorl
bearing 2 spiral carinas crossed by numerous closely
set axial riblets. Teleoconch of 14 whorls, the earlier
4 with 2 beaded spiral cords ;
a fine smooth cord
appears between them at the fifth whorl and becomes
beaded at the seventh whorl, beads only equal to the
other 2 rows on last whorl. Microsculpture appearing
lriphoridae of Reunion Island
between the cords, consists of very fine cords and
riblets intersecting at right angles. Aperture circular,
posterior canal recurved, a third hole on the left side of
aperture. Colour pale brown, beads slightly paler, the
2 earlier whorls of teleoconch whitish, protoconch
brown. Size 7 x 1.5 mm. Found in muddy sand at 10
m, cape La Houssaye, Saint Paul.
The species is quite valid.

species
Type locality. Reunion, cape La Houssaye, Saint
Paul, depht 10 m. Determined by locality of neotype.
Type material. None located. The type specimen of
“Triforis mirifica lifuana Hervier, 1898”, MNHN
1508 (type locality Lifou, New Caledonia) is present
in MNAHN, and does not show any obvious difference
with our material from Reunion. À neotype is here
designated, MNHN 9491 (Figs 20-22, 52).
Comments. Deshayes’ description and figure are of a
very distinctive species, remarkable by its 2 strongly
unequal spiral beaded cords on teleoconch whorls,
very long siphonal and anal canals and tube-like
aperture, and protoconch ornamented with 2 spiral
cords crossed by axial riblets.
This species 1s very common in Reunion, with more
than 200 specimens collected.
Description of the neotype. Shell regularly conical,
elongate and narrow. Protoconch consisting of 4
whorls, each one with 2 spiral carinas, the lowest
stronger, crossed by fine axial riblets, and tapering to

ornamented with 2 beaded spiral cords, strongly
unequal, the lower row of beads obviously stronger.
14 beads per whorl. Aperture small and circular,
siphonal canal recurved, anal canal long narrow
cylindrical, opposite to aperture. Colour creamy white,
the beads paler, protoconch and base light brown.
Size 7 x 1.5 mm. In dredged sand at 15 m, cape La
Houssaye, Saint Paul.

Paul, depth 20 m. Determined by locality of neotype.
Type material. None located. À neotype is here
designated, MNHN 9492 (Figs 23-24, 53).
Comments. Deshayes' description is of a short,
cylindrical shell, with a spire prolonging into a
pointed rostrum, hardly visible suture, and narrow
teleoconch whorls bearing 2 spiral rows of flattened,
wide, closely-set granules that are whitish on the
summit but arise from a blackish-brown ground,
dimensions 4 x 1.5 mm. The original illustration
shows a shell with an obviously broken protoconch.
We have found on Reunion a few specimens exactly
matching the description and figure of Deshayes, but
the species is very rare. This is a valid species. À few
smaller and paler specimens of same shape and
sculpture have been collected. They may also belong
to this same species.
Description of the neotype. Shell conical, wide,
restricted at base. Protoconch of 3 whorls, bearing 2
spiral carinas crossed by numerous axial riblets, and
tapering to a smooth rounded apex. Teleoconch of 8
whorls, 2 spiral rows of round beads numbering 18 per
whorl. A fine thread appears between the 2 cords,
smooth at the sixth whorl, bearing small beads at the
seventh whorl, remaining obviously smaller than the 2
other rows on last whorl. Ground colour blackish-
brown, beads paler, greyish on the upper row, whitish
on the lower row. Earlier whorls whitish, protoconch
brown. Size 4.5 x 1.8 mm. In dredged sand at 20m,
cape La Houssaye, Saint Paul.
Triphora reevei (Deshayes, 1863).

Type locality. Reunion, cape La Houssaye, Saint
Paul, depth 15 m. Determined by locality of neotype.
Type material. None located. A neotype is here
designated, MNHN 9493 (Figs 25-27, 54).
Comments. Deshayes' description is of a narrow,
elongate and pointed shell of white colour with a
blackish blotch, with 2 unequal rows of beads, the
abapical row (called the upper cord by Deshayes, on
account of his way to position the shells with the
aperture upwards) being stronger, a narrow, hardly
visible suture, size 5 x 1.25 mm. The illustration
shows a conical shell with 2 spiral beaded cords on
teleoconch whorls, the abapical cord being stronger.
In Reunion, a single species matches Deshayes'
description and figure.
Description of the neotype. Shell fusiform elongate,
pointed, base constricted. Protoconch of 3 whorls,
bearing 2 spiral carinas crossed by numerous closely-
set axial riblets, with a smooth rounded apex.
Teleoconch consisting of 12 whorls, bearing 2 spiral
cords crossed by axial ribs, with a strong bead at each
crossing, the beads of the lower cord stronger, 13 -14
beads per whorl. Aperture circular. Posterior canal
slightly recurved. Creamy white, the beads on the
lower cord paler, protoconch dark brown, a dark
brown blotch on siphonal canal. Height 8 mm. In
muddy sand at 15 m, cape La Houssaye, Saint Paul.
Triphora reevei (Deshayes, 1863), is a valid species.

A new species of Cosmioconcha (Gastropoda: Columbellidae)
from the northern Gulf of Mexico

KEY WORD. Gastropoda, Columbellidae, Cosmioconcha, Gulf of Mexico.
ABSTRACT. A new species of Cosmioconcha, dredged off the Alabama coast, northern Gulf of
Mexico, is described and compared to its congeners. It is the smallest of all western Atlantic
species of Cosmioconcha heretofore described.
INTRODUCTION
The Biology Department at the University of
Louisiana at Lafayette has conducted a series of
dredging cruises in the Gulf of Mexico. An important
objective of these cruises has been to try to have a
better understanding of the biodiversity of the Gulf.
This objective has been largely met with the
methodical study of the material collected, particularly
the micro-mollusks extracted from the sediment. The
dredged material has brought to light many molluscan
species previously unrecorded for that body of water
(see Garcia 1999b, 2000, 2002, 2003, 2007; and
Garcia & Lee 2002, 2003), as well as a number of
previously un-described species (see Garcia 1999a,
2005, 2006a, 2006b).
In the past year three new species of Cosmioconcha
from the western Atlantic have been described. Two
of these species, Cosmioconcha rikae Monsecour &
Monsecour, 2006 and C. geigeri Garcia, 2006, inhabit
the Gulf of Mexico. A third species, Cosmioconcha
nitens (C. B. Adams, 1850), also inhabits the Gulf. In
a cruise conducted during June-July, 2006, two empty,
but well- preserved shells of another species of
Cosmioconcha were obtained with a box dredge off
the coast of Alabama: and searching through material
collected in earlier cruises uncovered a third specimen
dredged in 2004 off the Louisiana coast.
Taking into consideration the new species described
herein, a full 50% of the described species of
Cosmioconcha from the western Atlantic will have
been reported from the Gulf of Mexico, and more than
35% will have been described in the very recent past.
These facts speak for the success of the work that has
been done in the Gulf in recent years, as well as for
the potential for many more future discoveries.
All cruises have been conducted on board the R/ V
“Pelican”, a research vessel owned and operated by
LUMCON, the Louisiana Universities Marine
Consortium.

E. F. GARCIA
A new species of Cosmioconcha
sharply marked by an abrupt change in color and
ornamentation (Fig. 4). Teleoconch of just over 3
whorls; first whorl almost flat-sided; following whorls
increasing in convexity. Suture deep, channeled. Axial
sculpture of few, sporadically placed, growth scars
(Fig. 2); one or two growth scars per whorl;
numerous, axially oriented microscopic threads give
the shell surface a wrinkled appearance (Fig. 5). Spiral
sculpture of incised, punctate spiral grooves; 9 such
grooves on first whorl, rapidly increasing in number
on later whorls; about 12 strong spiral cords appearing
at anterior end of last whorl; cords becoming slightly
nodulose when crossed by axial threads. Outer lip
strengthened by a moderately strong, wide varix (Fig.
2); ornamentation of last whorl continuing over
surface of varix. Aperture elongate-ovate,
approximately half the length of the shell; inner outer
lip showing 10 weak denticles; columella with a slight
swelling at anterior end, followed posteriorly by a
sharp, conspicuous denticle (Fig. 6); otherwise
smooth. Anterior canal short, wide. Shell color creamy
white, with tan, squarish markings that tend to form a
checkered pattern at suture and at periphery of last
whorl.
Discussion. Paratype 1 is slightly larger than the
holotype, measuring 5 mm in length and 2.1 mm in
width. It has all of the characters of the holotype,
including the rust-colored coloration at the end of the
protoconch, as well as the conspicuous denticle near
the base of the parietal wall. Paratype 2, the Louisiana
specimen, measures 4.2 mm in length but is chipped at
the anterior end. It is also slightly more eroded than
the Alabama specimens; otherwise, it shows all of the
important morphological characters and markings of
the other two type specimens.
There are seven columbellid taxa from the western
Atlantic that have been assigned to Cosmioconcha: C.
nitens (C. B. Adams, 1850), C. calliglypta (Dall &
Simpson, 1901), C. helenae (Costa, 1983), C.
humfreyi Jong & Coomans, 1988, C. dedonderi
Monsecour & Monsecour, 2006, C. rikae Monsecour
& Monsecour, 2006, and C. geigeri Garcia, 2006.
Cosmioconcha nitens, C. rikae and C. geigeri are
known to inhabit the Gulf of Mexico.
Cosmioconcha nitens has a multispiral protoconch,
lacks the conspicuous columellar denticle, has a
smooth surface except for the spiral cords at the base
of the last whorl, and has a proportionately longer
aperture; C. rikae 1s axially ribbed and has a nodulose
spiral cord anterior to the suture; and C. geigeri has a
Figures 1-7
white protoconch, stronger axial sculpture, a different
spiral sculpture, and a milky-white band at suture.
These three species are larger than Cosmioconcha
nana n. SP.
Cosmioconcha calliglypta, a southern Caribbean
species, 1s stouter, and has stronger sculpture.
Cosmioconcha helenae, a Brazilian species, has 6
whorls, is axially ribbed, and is nodulose at suture.
Cosmioconcha humfreysi, a species described from
Aruba, is more delicate, with a row of white spots
above the suture, and has 9 whorls. Cosmioconcha
dedonderi, from the southwestern Caribbean, has a
different color pattern and a cancellate sculpture. AII
of these species are also larger in size than
Cosmioconcha nana n. sp.
In his dissertation on Brazilian columbellids, Costa
(2005: 152-156) describes, without naming them, two
species from Brazil: Cosmioconcha "sp. 1", with axial
costae, 1s similar to €. rikae Monsecour &
Monsecour, 2006 in general shape and sculpture.
Cosmioconcha "sp. 2" is similar in size to the new
species; however, it is differently colored, has wider
shoulders, has a subsutural spiral sulcus, and different
surface ornamentation.
Etymology. From the Latin nanus (noun, meaning a
dwarf), in reference to the relatively small size of the
species when compared to its congeners. It is used
here as an adjective, meaning “of small size.”

RESUME. Diverses voies potentielles d’invasion de mollusques étrangers en Méditerranée sont
exposées. Celles-ci sont illustrées par nos données personnelles. Une attention particulière est
portée aux espèces lessepsiennes du golfe d’Iskenderun (Turquie) et des régions adjacentes (liste
des espèces de Méditerranée orientale en fin d’article).
ABSTRACT. The invasive molluscs species in the Mediterranean Sea. Different potential
means of introduction of alien species of mollusces into the Mediterranean Sea are presented. They
are illustrated by our personal data. Emphasis is put on the lessepsian species present in the Gulf of
Iskenderun (Turkey) and adjacent areas (list of the species of the Eastern Mediterranean enclosed
at the end of the publication).
Navigation is continuously increasing. Ships from all over the world are entering the
Mediterranean Sea. Release of their ballast waters is one of the main causes of introduction of
alien species. These invasive species will only be able to survive and to settle if they find a
favorable environment (temperature, light, salinity, food, support, absence of specific
predators.…).
Molluscs introduced for farming have a better chance to establish themselves in and out of the
shellfish farm. In fact they have been selected for their potential capabilities to adapt to their new
environment. Importation of species for aquaculture is not always mono-specific. Opportunistic
species accompany the commercial molluse and will establish themselves into the culture area but
they will also colonize adjacent regions.
Lessepsian species entering the Mediterranean Sea via the Suez Canal represent the bulk of the
invasive species. They can be found mainly along the Levantine coasts where the ecological
conditions are more or less similar to those of the Red Sea. A quick look below the surface of the
sea in these areas confirms the extension of this colonization. Some of the invasive species are
now dominant in the coastal submarine landscape. The future enlargement of the Suez Canal will
certainly increase this flow of invaders.
Present climatic changes, which increase the water surface temperature, will probably allow an
extension of the lessepsian migrants towards the Western Mediterranean.
Colonization via the Suez Canal is a dynamic process and an exhaustive inventory of Red Sea
migrants will never be complete. We are witnessing here a faunal modification which happens live
and is thus an exciting phenomenon.

La Méditerranée est une mer plus ou moins "fermée".
Cela délimite un cadre rigide pour réaliser l’inventaire
des espèces qui la peuplent et par conséquent pour
identifier la présence d’espèces invasives d’origines
diverses. A l’ouest, elle s’ouvre sur l’océan Atlantique
par le détroit de Gibraltar. Du côté de la mer Noire,
certains situent la limite de la Méditerranée aux
Dardanelles, d’autres y incluent la mer de Marmara et
repoussent sa frontière orientale jusqu’au Bosphore. A
Port Saïd, le canal de Suez lui donne accès à la mer
Rouge.
Bien sûr, la Méditerranée n’a pas toujours été telle
qu’elle se présente aujourd’hui. Lors du
fractionnement de la Pangée en deux grands
continents, 1l y a plus de 200 millions d’années, naquit
la Mésogée. Celle-ci se divisa ensuite en un océan
47
C. DELONGUEVILLE & R. SCAILLET
Les espèces invasives de mollusques en Méditerranée
Proto-Atlantique à l’ouest et à l’est en une étendue
d'eau nommée Téthys. Au cours du Miocène (- 17
Ma) un déplacement de la plaque de l’Afrique a
provoqué la fermeture de la mer Téthys à l’est, au
niveau du Moyen-Orient actuel, après avoir formé, à
l’ouest, le détroit de Gibraltar. La Méditerranée était
née. Il y a 5 millions d’années la communication avec
l'océan Atlantique fut momentanément interrompue,
période durant laquelle cette mer fut presque
totalement asséchée et où seuls persistaient quelques
"bassins" hypersalés (Ekman, 1953). Au Pliocène
supérieur, des variations du niveau des mers ont établi
des contacts successifs entre la Méditerranée et la mer
Rouge permettant ainsi divers échanges faunistiques
(Fishelson, 2000).
Nous ne remonterons pas si loin dans le temps pour
commenter la composition de la faune
méditerranéenne actuelle. Nous nous focaliserons sur
l’époque récente durant laquelle plusieurs événements
majeurs ont favorisé l'introduction d’espèces
étrangères en Méditerranée.
- Depuis la fin du 15° siècle, il y eut le développement
croissant de la navigation et l’arrivée en Méditerranée
de bateaux sans cesse plus grands, capables de faire
aujourd’hui d'immenses trajets autour du globe.
- Au 19° siècle, on entreprit le percement du canal de
Suez. La réalisation de cet ouvrage a permis
l'établissement d’une communication maritime
permanente entre la Méditerranée et la mer Rouge.
- Au 20° siècle, il y eut le développement de la
conchyliculture qui favorisa l’importation à grande
échelle d'espèces exotiques de mollusques.
- Il y a enfin la multiplication croissante d’aquariums
marins desquels certaines espèces peuvent s'évader
dans le milieu naturel environnant. On se souviendra
de l’épisode marquant du début des années 1980,
lorsqu'un laboratoire marin a laissé échapper l’algue
Caulerpa taxifolia (Vahl) C. Agardh, 1817. Elle s’est
rapidement multipliée et a envahi les fonds marins très
loin de la zone de sa première implantation
(Boudouresque et al., 1992). Cette invasion a exercé
une pression importante sur les écosystèmes locaux en
mettant en compétition l’intruse et les herbiers
d’origine. Il s’en est suivi une modification de la
composition des espèces qui leur étaient inféodées.
Pour survivre, s'établir, et coloniser de nouvelles
zones, dans un milieu qui n’est pas le leur, les espèces
invasives de mollusques doivent posséder des
caractéristiques particulières.
- Les espèces se reproduisant par larves planctoniques
peuvent parfois se déplacer sur de grandes distances.
Ces larves peuvent être emportées par les courants
marins et envahir des zones très loin de leur milieu
d’origine. Néanmoins, le risque est grand de terminer
le voyage dans des régions non propices à leur
installation.
- Les espèces à développement direct colonisent de
nouveaux territoires, de proche en proche, avec un
avantage: celui de déjà "connaître" le milieu adjacent.
48
- Les espèces qui s'installent avec succès sont aussi
celles qui tolèrent de grandes variations de leur
environnement, comme des modifications de
température, de salinité ou de luminosité. Leur
capacité d’adaptation à de nouveaux écosystèmes, à
un régime alimentaire différent, aux substrats
disponibles et aux polluants environnants favorise un
établissement durable. L'absence de prédateurs
spécifiques joue également un rôle décisif dans la
réussite d’une nouvelle implantation.
D'autre part, les voies d’introduction qu’empruntent
les mollusques influencent également leurs chances de
s'installer avec ou sans succès dans un nouveau
milieu.
- Les espèces de mollusques apportées par la voie
maritime ont une probabilité d’implantation réussie
aléatoire. Il arrive que l’environnement dans lequel
elles aboutissent ne soit pas propice à leur installation.
L'introduction d’un nombre insuffisant d’individus
génétiquement différents peut être à l’origine d’un
échec de l’implantation. Cependant, la pression
environnementale sur un petit nombre d’individus
transplantés peut donner naissance à de nouvelles
populations en voie de spéciation (Boero, 2002).
- Les espèces empruntant le canal de Suez comme
voie d’accès à la Méditerranée s’établissent de
préférence le long des côtes levantines, là où les
conditions de températures ressemblent le plus à celles
de la mer Rouge.
- Les espèces introduites en vue de l’aquaculture ont
plus de chance de réussir leur acclimatation
puisqu'elles sont sélectionnées pour leurs capacités
potentielles à s’établir dans leur nouveau milieu.
La CIESM (Commission Internationale pour
l’Exploration Scientifique de la Méditerranée), dont le
quartier général est établi à Monaco, a entre autres
buts celui de recenser toutes les espèces invasives en
Méditerranée. Ce travail a fait l’objet de publications
pour les poissons (Golani et al., 2002) et pour les
invertébrés, tels que les crustacés (Galil et al., 2002) et
les mollusques (Zenetos et al., [2003] 2004). Ce
troisième volume de l’atlas des espèces exotiques de
Méditerranée et les travaux de Mienis (2004) donnent
accès à la liste la plus complète des espèces invasives
répertoriées à ce jour en Méditerranée. La rédaction du
présent travail est basée sur l’ensemble de nos récoltes
personnelles et ne représente pas un inventaire
exhaustif des espèces invasives. Nous n’abordons
d’ailleurs ici que les bivalves et les gastéropodes
limités aux espèces pourvues d’une coquille.
LES VOIES D’ACCES A LA MEDITERRANEE
Différentes voies d’accès potentielles sont examinées
ci-dessous. Pour certaines, il existe un lien direct entre
un événement déterminant et l’arrivée d’un
envahisseur en Méditerranée. Pour d’autres, il s’agit
d’hypothèses, le mode ou la voie d’invasion n’étant
pas identifié avec certitude. Enfin, il est possible que
toutes les voies potentielles d’accès n’aient pas encore
été découvertes.
C. DELONGUEVILLE & R. SCAILLET
Les voies d’accès géographiques naturelles
Les voies d’accès naturelles à la Méditerranée se
situent à Gibraltar et au niveau de la mer de Marmara.
- Dans le détroit de Gibraltar, la Méditerranée coule en
profondeur vers l’océan et les eaux de surface de
l’océan entrent en Méditerranée (Bray et al., 1995).
Ces courants brassent des quantités d’eau importantes
en mer d’Alboran (Méditerranée) et au sud de la
péninsule ibérique (océan Atlantique). Cette région est
riche en espèces endémiques. Il existe aussi des
espèces qui depuis des siècles vivent de part et d’autre
du détroit. On parlera dans ce cas d’expansion
naturelle entre zones contigües plutôt que d’invasion.
- Au niveau de la mer de Marmara, la mer Noire coule
en surface vers la Méditerranée et cette dernière,
évolue en profondeur vers la mer Noire (Leier, 2001:
Kideys, 2002). Historiquement, une partie de la faune
de la mer Noire est d’origine méditerranéenne. Elle
s’y est installée lorsque les deux mers sont entrées en
communication voici bien longtemps. Etant donné la
pauvre biodiversité et la faible salinité de la mer
Noire, on n’observe pas de migrations significatives
de mollusques vers la Méditerranée. Les conditions
écologiques de ces deux mers sont pour beaucoup
d’espèces bien trop différentes. Par contre, certaines
espèces invasives ont réussi à s’adapter aux conditions
particulières de la mer Noire (Çeviker, 2002a). On
retrouve sur les côtes roumaines (Constanta) des
espèces comme Anadara inaeqguivalvis (Bruguière,
1789) - Arcidae indo-pacifique et Mva arenaria
Linnaeus, 1758 (Fig. 4) - Myidae d’origine nord-
atlantique.
Une voie d’accès géographique artificielle
Le canal de Suez relie aujourd’hui la Méditerranée à la
mer Rouge (Carte 1). Il a été creusé sous la direction
de Ferdinand de Lesseps et inauguré en 1869. Depuis
cette époque, il constitue une voie d’accès permanente
à la Méditerranée. Chaque année, plus de 20.000
navires empruntent son passage. Ce canal est un
vecteur de migration de mollusques d’une mer à
l’autre. La colonisation "naturelle" est le fait d'espèces
se déplaçant par leurs propres moyens. Toute
"naturelle" soit-elle, elle trouve cependant son origine
dans un acte humain qui est celui d’avoir relié entre
elles deux mers sans contact depuis des temps
lointains. Les espèces qui entrent en Méditerranée par
le canal de Suez sont appelées "lessepsiennes". Le
terme est inspiré du nom de Ferdinand de Lesseps qui
fut le concepteur de ce canal. Pour mériter cette
appellation, l’espèce doit à la fois se retrouver en mer
Rouge, dans le canal de Suez et en Méditerranée. Les
espèces effectuant le trajet migratoire en sens inverse
sont appelées ‘"anti-lessepsiennes". De nombreux
exemples de ce phénomène de migration inverse sont
rapportés dans la littérature (Barash & Danin, 1987).
Ils montrent que les colonisations peuvent
évidemment se produire dans les deux sens. La
NOVAPEX 8 (2): 47-70, 10 octobre 2007
Méditerranée peut servir, elle aussi, de base arrière à
des mollusques envahisseurs de la mer Rouge. Parfois
la situation est moins claire : Smaragdia souverbiana
(Montrouzier, 1863) - Neritidae - (Fig. 3) est un
gastéropode de mer Rouge; on ne le signale
momentanément pas dans le canal de Suez, mais il est
bien présent le long des côtes orientales de Turquie
(Liman Kalesi et Tasucu, récoltes personnelles:
spécimens vivants dans les herbiers à quelques
décimètres de profondeur). Il n’est donc pas certain
que l’espèce ait migré d’elle-même via le canal: son
mode d’introduction reste encore sujet à discussion.
Carte 1. Aperçu schématique du canal de Suez
1. Mer Méditerranée. - 2. Port Saïd. - 3. Canal d’eau
douce. - 4. Great Bitter Lake. - 5. Small Bitter Lake. -
6. Port Suez. - 7. Mer Rouge.
Hoffman et al. (2006) donnent des informations
concernant des coquilles présentes dans le canal de
Suez ainsi que dans le "Great Bitter Lake" (situé aux
deux tiers du chemin entre la Méditerranée et la mer
Rouge). Quoiqu’encore fort salé, ce lac pourrait être
considéré comme la "salle d’attente" des migrants
potentiels qui ne sont pas encore présents en
Méditerranée. Il ne faut pas oublier que lors de
l’ouverture du canal, le "Great Bitter Lake" contenait
de l’eau extrêmement salée et constituait une barrière
naturelle au passage de nouvelles espèces venant de
l’une ou de l’autre mer. De plus, le Nil apportait de
grandes quantités d’eau douce entre ce lac et la
49
C. DELONGUEVILLE & R. SCAILLET
Méditerranée, ce qui constituait une seconde barrière
naturelle aux migrations. Aujourd’hui, la situation a
changé. Premièrement, la présence du barrage
d’Assouan a fortement limité l’apport d’eau douce
dans le delta du Nil et par conséquent dans le canal de
Suez. Le bras du Nil nourrissant en eau douce
l'extrémité du canal n’est quasiment plus fonctionnel
(Leier, 2001). Deuxièmement, le canal a été élargit en
1981 et le sera encore d'ici 2010. Ces aménagements
successifs augmentent le flux d’eaux marines entre les
deux mers aujourd’hui reliées entre elles. Ceci
explique le recensement sans cesse plus grand
d'espèces lessepsiennes en Méditerranée. En outre, il
ne faut pas négliger l’intérêt croissant des chercheurs
pour cet important phénomène de migration animale.
Les voies d’accès maritimes
Le transport par l’intermédiaire de navires est souvent
cité comme l’une des causes de l’essaimage de
certaines espèces de mollusques.
- Des mollusques peuvent utiliser la coque des bateaux
comme support pour leur développement. Il s’agit
d'individus adultes incrustés ou de pontes attachées
sous la ligne de flottaison. Ils peuvent de la sorte être
transportés et coloniser de nouvelles régions loin de
leur lieu d’origine.
- L’eau de mer aspirée pour remplir les ballasts des
navires peut contenir des œufs, des larves, ou mêmes
des coquilles adultes. Ces organismes sont transportés
sur des milliers de kilomètres. S’ils survivent au
voyage, ils peuvent être relâchés dans un autre lieu, au
hasard d’une purge de ballasts, et y faire souche à
condition de trouver un milieu propice à la poursuite
de leur développement ou de leur vie (Zibrowius,
2002). Cette hypothèse a été formulée pour expliquer
le passage de Strombus persicus Swainson, 1821 -
Strombidae - (Fig. 1) du golfe Persique à la
Méditerranée. Les navires accostant aux terminaux
pétroliers du golfe d’Iskenderun (Turquie orientale)
seraient à l’origine de l’introduction de l’espèce
(Oliverio, 1995). Cependant, cette théorie a été
récemment mise en doute (Gofas & Zenetos, 2003).
Thais lacera (Born, 1778), Muricidae de l’océan
Indien, illustre également une colonisation probable de
ce type. Dans une deuxième étape, l’espèce aurait
migré de la Méditerranée vers le canal de Suez pour
atteindre secondairement le nord de la mer Rouge
(Mienis, 1994). L’exemplaire vide illustré en Fig. 5
provient de Paphos (Chypre).
Figures 1 - 7
Les espèces invasives de mollusques en Méditerranée
La voie d’accès aérienne
Certains oiseaux ont été cités comme probables
vecteurs de transport de mollusques. Faber (1999)
évoque le déplacement possible de juvéniles de
Cerastoderma glaucum (Poiret, 1789) et de Potamides
conicus (de Blainville, 1829) par la boue collée aux
pattes de .migrateurs fréquentant des zones
marécageuses dans lesquelles ces espèces vivent. Il
explique de la sorte leur présence dans un lac d’eau
saumâtre voisin du Nil (lac Qarum) n’ayant jamais eu
de communication avec une mer. Il est possible qu’un
tel phénomène puisse se produire ailleurs.
Les aquariums et centres de recherches
scientifiques
Outre l’introduction accidentelle (réussie) de l’algue
Caulerpa taxifolia déjà mentionnée ci-dessus, on peut
citer celle (probablement avortée) du nudibranche
Chromodoris quadricolor (Rüppell & Leuckart,
1830). Il a été retrouvé une seule fois dans le nord de
l'Italie et provenait plus que probablement d’un
aquarium marin situé dans la région (Zenetos et al.
[2003] 2004).
La conchyliculture
En Europe, depuis le début des années 1960, cette
pratique est en croissance continue. Elle a donné lieu à
l'installation délibérée en Atlantique et en
Méditerranée de nombreux envahisseurs. Cette fois, la
colonisation se produit de façon massive. Le but est
évident: acclimater des espèces étrangères et les faire
croître dans un autre milieu à des fins commerciales.
On importe en un lieu prédéterminé une grande
quantité d’individus dont certains finissent par
s’échapper de leur zone de culture pour essaimer de
proche en proche. Dans la majorité des cas, cet apport
d'espèces étrangères n’est pas monospécifique. Il
s'accompagne de la présence d’espèces opportunistes
sans valeur commerciale qui à leur tour vont s’établir
dans et en dehors des zones de culture. Il arrive aussi
que l’on déplace des populations de mollusques d’un
endroit à l’autre, soit pour initier la culture ailleurs,
soit pour installer les mollusques dans un
environnement de croissance plus favorable. En
France, des huîtres sont ainsi déplacées de l’océan
Atlantique vers la Méditerranée entrainant le transfert
d'espèces associées qui peuvent à leur tour devenir
invasives.

Les espèces invasives de mollusques en Méditerranée
- Les espèces destinées à l'élevage
- Crassostrea gigas (Thunberg, 1793). Cet Ostreidae a
été importé du Pacifique Nord en France dans les
années 1960 pour remplacer les populations
atlantiques d’huîtres creuses [Crassostrea angulata
(Lamarck, 1819)] décimées par des épizooties (Vidal,
2001). Par la suite, cette huître a été introduite dans les
étangs du midi de la France et en Adriatique à des fins
de culture. Spécimens en collection: Laguna di
Ravenna, Lido di Sottomarina, Aquilea (Fig. 7), Grado
(Italie - Adriatique), Gruissan, étangs de Mèze et de
Leucate (sud de la France) et Karatas (Fig. 6)
(Turquie). Cette dernière provenance confirme
aujourd’hui l'expansion de l’espèce jusqu’à l’est de la
Méditerranée.
- Ruditapes philippinarum (Adams & Reeve, 1850).
Ce Veneridae de l’ouest de l’océan Pacifique, encore
appelé palourde de Manille, a été introduit avec succès
en Adriatique (Cesari & Pellizzato, 1985) et en France
à des fins d’élevage. Il a très rapidement essaimé dans
les régions avoisinantes. En Méditerranée, tout comme
dans l'océan Atlantique, Ruditapes philippinarum
entre en compétition directe avec l’espèce autochtone
Ruditapes decussatus (Linnaeus, 1758). La densité de
population de cette dernière diminue dans son milieu
d’origine, jusqu’à disparaitre quasi totalement de
certaines régions au profit de l’espèce allochtone. Ce
fait est particulièrement marqué sur la façade
atlantique de l’Europe. Spécimens en collection:
embouchure du P& [Italie - Adriatique (Fig. 2)] ; étang
de Leucate (France); Istanbul (mer de Marmara -
Turquie).
- Les espèces opportunistes accompagnantes
- Haminoea callidegenita (Gibson & Chia, 1989). Cet
Haminoeidae de l’océan Pacifique a été importé dans
l'Atlantique, en France et en Espagne avec des
mollusques destinés à l’aquaculture. De là, il a été
accidentellement exporté en Adriatique en même
temps que la palourde de Manille (Alvarez et al.
1993). Spécimens en collection : Laguna di Ravenna
(Fig. 8).
- Crepidula fornicata (Linnaeus, 1758). Ce
Calyptraeidae a été importé des côtes atlantiques de
l'Amérique du Nord vers l’Angleterre à la fin du 19°
siècle, à l’occasion de transferts d’huîtres. Il a fait
route vers la France lors des mouvements de navires
durant la seconde guerre mondiale. Ensuite, il a
accompagné de manière massive Crassostrea gigas en
provenance du Japon et de la Colombie Britannique
(Blanchard, 1995). La biomasse des crépidules en
Atlantique se chiffre localement en milliers de tonnes
(Blanchard & Ehrhold, 1999). L’espèce a finalement
été transférée dans le midi de la France lors des
transports d’huîtres entre l’Atlantique et la
Méditerranée. Spécimens en collection: Le Grau du
Roi et zones ostréicoles de Gruissan et de l’étang de
Thau (Fig. 9) (France). On note également une
extension de l’espèce vers l’Espagne (spécimen en
collection : Blanes).
- Xenostrobus securis (Lamarck, 1819). Ce Mytilidae,
établi dans la zone tropicale de l’océan Pacifique, a été
signalé une première fois dans la lagune de Ravenna,
puis s’est rapidement introduit dans le nord de
lAdriatique en se propageant sur les pilastres
('hricoli") de la lagune de Venise (Sabelli &
Speranza, 1994). Il s’étend actuellement en grandes
colonies dans le delta du Pô. Une nouvelle
implantation massive est également signalée en France
au Grau du Roi, où le mollusque cohabite avec un
autre Mytilidae, Musculista senhousia (Benson in
Cantor, 1842) (Russo, 2001). Spécimens en collection:
marina di Ravenna - laguna di Caleri (Fig. 10) et
Fusina (Italie - Adriatique).
COMBINAISON DES VOIES D’ACCES
Il est probable que certains mollusques puissent
emprunter simultanément ou chronologiquement
différentes voies d’accès. Une espèce peut s’introduire
par le canal de Suez, faire souche le long des côtes
levantines et être en même temps transportée à des
endroits forts distants les uns des autres par la voie
maritime. Les quelques exemples qui suivent en
témoignent.

Anadara inaequivalvis (Bruguière, 1789). Cet
Arcidae indo-pacifique a été importé accidentellement
en mer Adriatique, probablement par l’intermédiaire
de bateaux. Il s’est développé exponentiellement dans
le golfe de Venise et le long des côtes nord-est de
l'Italie, région où sa biomasse est actuellement
gigantesque. Il a ensuite été transplanté vers la Sicile,
probablement avec des envois de Chamelea gallina
(Linnaeus, 1758) - Veneridae destiné à l’aquaculture.
Spécimens en collection: Chioggia, Grado, Cervia,
Goro (estuaire du PGô), Lido degli Estensi (Fig. 11) en
Italie (Adriatique); Rumeli Kavagi dans le Bosphore
(Turquie).
- Pinctada radiata (Leach, 1814). L'extension de ce
Pteriidae, dont la présence est déjà mentionnée en
Egypte en 1874, semble actuellement couvrir
l’entièreté du bassin oriental de la Méditerranée. Il y
est apparu par colonisation naturelle au départ du
canal de Suez (origine indo-pacifique) et / ou par
apport anthropique pour la culture de perles.
Spécimens en collection: La Laouza, Djerba (Fig. 12)
et Iles Kerkennah (Tunisie); Bath of Aphrodite
(Chypre); Side, Liman Kalesi, Tasucu, Narlikuyu et
Burnas (Turquie).
- Musculista senhousia (Benson in Cantor, 1842). Ce
Mytilidae de l’ouest de l’océan Pacifique (Fig. 13) est
abondant dans les zones où se pratique l’aquaculture.
Chaque année, son aire de répartition s’agrandit,
comme en témoigne une collecte récente réalisée à
Cagliari - sud de la Sardaigne (Delongueville &
Scaillet, 2006a). Les premières introductions
proviennent de la conchyliculture et les découvertes de
la côte levantine sont le fait d’une migration en
provenance du canal de Suez. Spécimens en
collection: étangs de Leucate, de Thau, de Gruissan,
les Saintes-Maries-de-la-Mer (Sud de la France);
laguna di Ravenna, laguna di Venezia, embouchure du
P6 (Adriatique) et Cagliari (Sardaigne).
- Rapana venosa (Valenciennes, 1846). L’arrivée de
ce Muricidae de l’océan Pacifique en mer Noire
(1946) et en mer Adriatique (1974), régions distantes
entre elles de plus d’un millier de km, est très
certainement le fait de deux événements successifs et
distincts: l'introduction de larves planctoniques
provenant de l’eau des ballasts de navires déversée en
mer Noire (Kideys, 2002) et l’introduction de pontes
Figures 16 - 24
Les espèces invasives de mollusques en Méditerranée
accompagnant des produits d’aquaculture en
Adriatique (Zenetos et al., 2005). Spécimens en
collection: Rumeli Kavagi, Rumeli Fenner (confins du
Bosphore); Tekirdag en mer de Marmara (Fig. 14);
Rimini (Adriatique).
- Erosaria turdus (Lamarck, 1810) est considérée
comme une espèce lessepsienne de Cypraeidae dont la
présence est signalée en Israël, en Egypte et en mer
Rouge (Zenetos et al., [2003] 2004). Depuis 2004, de
nombreuses publications font état de sa présence dans
le golfe de Gabès (Delongueville & Scaillet, 2004b)
(Fig. 15) et plus particulièrement de la collecte
d'individus vivants à Djerba - Tunisie (Wimart-
Rousseau, 2004; Demartini, 2005; Boyer & Simbille,
2005). Rien n’explique, à l’heure actuelle, la présence
de l’espèce dans cette région. S’agit-il d’une
colonisation en provenance de la Libye et des côtes
avoisinantes dont les données à ce sujet font défaut, ou
d’un apport anthropique accidentel?
- Fulvia fragilis (Forskäl, 1775). Ce Cardiidae de
l’océan Indien est présent en Tunisie. A Djerba, il est
rejeté en grande quantité sur la bande côtière de
Fahmine (Fig.20). Il est également signalé dans la
partie est de la Méditerranée et dans le canal de Suez.
Comment a-t-1l migré vers la Tunisie ? Des relevés
faunistiques entre l'Egypte et Djerba font défaut. Un
apport anthropique par des navires n’est pas à exclure.
En effet, la présence de l’espèce a été sporadiquement
signalée en Grèce (Vardala-Theodorou, 1999), en
Espagne (Zenetos et al., [2003] 2004) et récemment en
Italie dans le golfe de Naples (Crocetta, 2005).
Spécimens en collection: Fahmine (Djerba - Tunisie).
VOIES D’ACCES INCONNUES
A titre d'exemples, les deux petites espèces suivantes,
originaires de la région indo-pacifique, sont qualifiées
de rares en Méditerranée; leur voie d’introduction
reste à ce jour énigmatique.
- Sticteulima lentiginosa (Adams A., 1861). Cet
Eulimidae (Fig. 16) rarement trouvé (Zenetos et al.,
[2003] 2004) a été également isolé par nos soins en
2005 parmi les concrétions extraites d’une vingtaine
de Spondylus spinosus Schreibers, 1793 (Yumurtalik -
20 à 30 m de fond - golfe d’Iskenderun - Turquie). Sa

Les espèces invasives de mollusques en Méditerranée
- Murchisonella columna (Hedley, 1907). Nous avons
collecté ce minuscule Cimidae (Fig. 18) en 2005 dans
une laisse de mer prélevée sur la plage de Karatas
(golfe d’Iskenderun - Turquie). Ce mollusque
d’origine indo-pacifique est rarement signalé le long
des côtes orientales de la Turquie (Mienis, 2004) et
son mode d'introduction en cet endroit reste inconnu
(Zenetos et al., [2003] 2004).
PERENNITE OU
L’'INSTALLATION
FRAGILITE DE
Si certaines espèces semblent fermement établies de
place en place f[exemples: Srrombus persicus,
Brachidontes pharaonis (P. Fischer, 1870)], d’autres
s'installent temporairement, puis disparaissent
définitivement ou réapparaissent sporadiquement à
d’autres endroits.
- Anadara demiri (Piani, 1981). Cet Arcidae indo-
pacifique (Fig. 17) a été récolté dans le port d’Izmir
(Turquie) duquel il aurait aujourd’hui disparu
(Zenetos et al., [2003] 2004) pour réapparaître dans le
golfe de Thermaikos, la baie de Thessaloniki (Grèce)
(Zenetos, 1994) et de manière plus abondante en
Italie, au centre de la mer Adriatique - sud de la région
d’Ancona (Morello & Solustri, 2001). Ce bivalve
semble bien s'adapter dans des conditions portuaires
aux eaux fortement polluées. Spécimens en collection:
Izmir 1996 (date de collecte validée).
- Saccostrea commercialis (Iredale & Roughley,
1933). Cet Ostreidae d'Australie a été importé dans la
lagune de Venise (Chioggia) à des fins de culture
(Cesari & Pellizzato, 1985). Depuis 1990, sa présence
n'aurait plus été signalée (Zenetos et al., [2003] 2004).
Ces deux exemples démontrent qu’un établissement
ferme reste toujours aléatoire et qu’il faut parfois de
nombreuses années pour qu’un ancrage définitif
Fig 25 - 35
réussisse, Il suffit aussi que les conditions
environnementales changent pour transformer un
succès d'établissement ponctuel en un échec.
PRESENCES INVASIVES CONTESTEES
La présence de certaines espèces invasives est rejetée
par la littérature. Cependant, des spécimens figurent
souvent au sein de collections privées. Retenons à titre
non exhaustif les exemples suivants:
- Umbonium vestiarium (Link, 1807). Ce Trochidae
des Philippines a été collecté en Libye en 1969, et
mentionné une seule fois dans la littérature (Zenetos et
al., [2003] 2004). Mienis (2004) l’exclut de la liste des
espèces invasives en Méditerranée. Spécimens en
collection: Paphos (Chypre) 1989 - exemplaires vides,
localisation validée (Fig. 19). Haïfa (Israël), 1987 et
Alexandrie (Egypte), 1999 - exemplaires operculés -
acquisitions, sans possibilité de validation certaine.
- Coralliobia madreporarum (Sowerby, 1832). La
récolte dans les Pouilles (Italie) de 3 spécimens de ce
Coralliophilinae indo-pacifique (Fig. 21) a été signalée
comme étant exceptionnelle (Oliverio, 1989). Depuis,
ce mollusque n’a plus fait l’objet de publications
prouvant son établissement définitif en Méditerranée.
L'espèce a été récemment exclue de la liste des
envahisseurs de la Méditerranée. Spécimens en
collection: au large de Ravenna (Italie) - (80 m) -
acquisition, sans possibilité de validation certaine.
- Erronea caurica Linnaeus, 1758. Bien que
également rejeté par Zenetos et al. ([2003] 2004) et
Mienis (2004), ce représentant des Cypraeidae est
rapporté de Rhodes (Barash et Danin, [1988] 1989),
de Chypre (Giannuzzi-Savelli et al., 1997), de El
Arish (Egypte - Barberini & Fuschi : communication
personnelle) et de Haïfa (acquisition, sans possibilité
de validation certaine) (Fig. 23).

Les espèces invasives de mollusques en Méditerranée
FAUSSES INTRODUCTIONS
Des rejets anthropiques peuvent donner lieu à de faux
rapports d'introduction. Si l’espèce n’est pas trouvée
vivante, en plusieurs exemplaires et à plusieurs
reprises ou si sa présence est totalement aberrante
dans le milieu, 1l peut s’agir d’un rejet accidentel ou
volontaire dû à une quelconque activité humaine.
- Sur la plage de Riccione (Italie), trois espèces indo-
pacifiques ont été répertoriées (Tisselli et al., 2005):
Pyramidella dolabrata (Linnaeus, 1758), Dentalium
octangulatum Donovan, 1804 et Pupa sp. Il ne s’agit
pas d'espèces migrantes. Elles proviennent du sable
contenu dans des sachets d’appâts destinés à la pêche
à la ligne, importés de Taiwan. Lorsque les vers ont
été utilisés, le sable est rejeté sur la plage avec son
contenu en petites coquilles exotiques. Tôt ou tard,
elles sont retrouvées par un collectionneur
s'intéressant au contenu malacologique des laisses de
mer locales.
ESPECES DITES INVASIVES MAIS EN FAIT
DE SOUCHE MEDITERRANEENNE
Il est des espèces dites invasives qui ne sont plus
considérées comme telles.
- Potamides conicus (de Blainville, 1829). Ce
Potamididae ne fait plus partie du groupe des espèces
lessepsiennes. La découverte d’un fossile en région
méditerranéenne laisse supposer que cette espèce
serait native de Méditerranée (Zenetos et al., [2003]
2004). De plus, Hoffman et al. (2006) précisent que
l’espèce était présente en mer Rouge et en mer
Méditerranée avant l’ouverture du canal de Suez. Elle
pourrait avoir été transportée par des oiseaux (Faber,
1999). Spécimens en collection: Marsaxlokk (Malte),
Viareggio (Italie), Faliraki (Rhodes), Djerba et Iles
Kerkennah (Tunisie), Tasucu (Turquie), Akko (Fig.
22) (Israël).
- Alvania dorbignyi (Audouin, 1826) (Fig. 24). Lors
de sa première signalisation en Méditerranée, ce
Figures 36 - 43
Rissoidae a été qualifié d’espèce lessepsienne sur base
d'une représentation dans une planche de Savigny
datée de 1805. Celle-ci était sensée représenter des
mollusques d'Egypte provenant de la mer Rouge. Il a
été démontré ultérieurement que certaines des
coquilles figurées dans ce document étaient des
espèces méditerranéennes. Mienis (1985) a émis
l'hypothèse qu’A/vania dorbignyi n’existait pas en
mer Rouge et qu’il s’agissait d’une espèce endémique
de l’est de la Méditerranée. L’absence de collecte
récente de ce mollusque en mer Rouge vient à l’appui
de cette thèse (Dekker & Orlin, 2000). Zenetos et al.
([2003] 2004) considèrent toujours l’espèce comme
lessepsienne ce que continue de réfuter Mienis (2005).
- Cylichna cf mongii (Audouin, 1826). Ce Cylichnidae
a été présenté comme une espèce lessepsienne
(Cecalupo & Quadri, [1995] 1996), mais il semblerait
que l’on soit en présence d’une espèce
méditerranéenne non décrite à ce jour (Zenetos et al.,
[2003] 2004). Spécimens en collection: nombreuses
localités sur les Iles Kerkennah et à Djerba (Tunisie)
(Fig. 25); Side, Tasucu (Turquie).
LA LESSEPSIE
Nous appelons "Lessepsie" (Carte 2) la région
comprise entre le canal de Suez, les côtes d'Egypte, de
Palestine, d’Israël, du Liban et de la Syrie, le golfe
d’Iskenderun, les côtes contiguës de la Turquie ainsi
que celles de Chypre. Pourquoi cette appellation toute
personnelle? Parce que lorsqu’on porte sur une carte
les provenances connues de chacune des espèces de
mollusques lessepsiens, ou réputés tels, se dessine une
zone de la Méditerranée orientale où les découvertes
sont denses et nombreuses. Tenant compte de
l’absence de publications récentes concernant des
relevés faunistiques sur la côte à l’ouest du delta du
Nil (Egypte et Libye), on ne peut infirmer que la
colonisation lessepsienne ne se dirige pas également
vers l’ouest du canal de Suez. Néanmoins, trois
critères importants sont à prendre en compte.

Les espèces invasives de mollusques en Méditerranée
Carte 2. "La Lessepsie"
1. Turquie. - 2. Syrie. - 3. Liban. - 4. Israël et
Territoires palestiniens. - 5. Egypte.
- Le sens de circulation des courants marins côtiers
de surface. Ceux-ci tournent dans le fond de la
Méditerranée, dans le sens inverse des aiguilles d’une
montre. Ils viennent de la Libye et de l’Egypte,
passent au large de Port Saïd, remontent le long des
côtes du Moyen-Orient, s’enroulent vers l’ouest dans
le golfe d’Iskenderun, et prolongent leur course le
long des côtes turques vers les îles grecques de la mer
Egée (Hamad et al., 2005). Ceci peut expliquer le flux
migratoire quasi unidirectionnel des mollusques
lessepsiens du sud-est en ouest.
- La présence du delta du Nil. Situé à l’ouest de
lembouchure du canal de Suez, il apporte une
quantité importante d’eau douce et d’alluvions en
Méditerranée. Ces apports pourraient constituer une
barrière écologique naturelle à la propagation vers le
sud-ouest des espèces lessepsiennes. Il est à noter que
le flux d’eau douce est actuellement moins important
que par le passé, le barrage d’Assouan contrôlant à ce
jour les crues des eaux du Nil. Seul un inventaire des
mollusques marins présents à l’ouest d'Alexandrie et
en Libye pourrait nous éclairer sur la validité de ces
théories et sur l’étendue géographique de la
"Lessepsie".
- Des conditions écologiques favorables. Il faut
également que les espèces issues du canal de Suez
trouvent des conditions écologiques optimales pour
Figures 44 - 51
s'adapter en Méditerranée, ce qui semble être le cas
dans sa partie orientale. On y recense à ce jour la
présence de plus d’une centaine d’espèces de
mollusques lessepsiens et indo-pacifiques (Mienis,
2004). Les conditions de températures sont fort
différentes dans le bassin ouest de la Méditerranée, ce
qui pourrait constituer un frein à une expansion rapide
et massive des espèces dans cette direction. Les
changements climatiques en cours pourraient
influencer eux aussi la dispersion présente et future
des espèces en modifiant entre autres la température
des eaux de surface.
EXPLORATION PARTIELLE DES ESPECES
INVASIVES DE MOLLUSQUES DU GOLFE
D’ISKENDERUN ET DES ZONES
ADJACENTES
Il existe à l’heure actuelle une nouvelle communauté
de mollusques dans la Méditerranée orientale, qui est
un mélange d’espèces méditerranéennes et invasives,
ce que Fishelson (2000) appelle la communauté "Red -
Med". La biodiversité reste en faveur des espèces
méditerranéennes mais certaines espèces de mer
Rouge deviennent dominantes en nombre d’individus
et donc réellement invasives (Gofas & Zenetos, 2003).
La côte sud-est de la Turquie (Carte 3), comprise entre
Tasucu et la frontière syrienne est particulièrement
riche et dense en espèces de mollusques invasifs,
lessepsiens ou supposés tels (Çevik & Sarihan, 2004).
Certaines espèces présentes en mer Rouge se
retrouvent dans le golfe d’Iskenderun mais ne sont pas
toutes signalées dans le canal de Suez et / ou le long
des côtes levantines. Elles occupent toutes les niches
écologiques côtières. Des renseignements concernant
les eaux profondes font défaut.
A l’ouest de Mersin, la région de Tasucu se caractérise
par une succession de baies peu profondes
entrecoupées de quelques plages de sable. Les espèces
invasives y sont nombreuses (Buzzuro & Greppi,
1996). Sur les fonds, les rochers alternent avec des
zones de sable et des herbiers denses. L’espèce
dominante est Sfrombus persicus Swainson, 1821
(Fig. 1) qui a réussi à s’installer, grâce à sa larve
planctotrophe, jusqu'aux confins du Péloponnèse et
des îles grecques (Zenetos et al., 2005). Sur la frange
rocheuse, à fleur d’eau, se côtoient de nombreux
Spondylus spinosus Schreibers, 1793 et/ou Spondylus

Les anfractuosités des rochers de la côte sont occupées
par d’immenses colonies de Malvufundus regula
(Forskäl, 1775) (Fig. 26) dont les spécimens s’alignent
verticalement les uns à coté des autres. Sur les rochers,
de nombreux exemplaires de Brachidontes pharaonis
(Fischer P., 1870) (Fig. 27) sont fermement accrochés
par leur byssus. Un mètre cinquante plus bas, le sable
alterne avec des blocs rocheux épars de petite taille.
Sur le sable gisent des coquilles de bivalves morts
parmi lesquelles de nombreux spécimens de
Gafrarium pectinatum (Linnaeus, 1758) (Fig. 29). A
la surface des petits rochers, d’innombrables
Cerithium scabridum Philippi, 1848 (Fig. 30) broutent
la végétation. Sous ces rochers, la vie est intense:
Ergalatax obscura Houart, 1996 (Fig. 31) est fort
abondant. Sur les surfaces rocheuses lisses on trouve
des spécimens de Diodora ruppellii (Sowerby G.B. I,
1835) (Fig. 32) et de Purpuradusta gracilis notata
(Gill, 1858) (Fig. 33). Plus loin, mais toujours à faible
profondeur, s’étendent de grands herbiers sur les
feuilles desquels vivent de petites espèces comme
Figures 52 - 59
Smaragdia souverbiana (Montrouzier, 1863) (Fig. 3),
Gibborissoa virgata (Philippi, 1849) (Fig. 34), Diala
varia Adams A., 1861 (Fig. 35), Rissoina bertholleti
Issel, 1869 (Fig. 36), Zafra savignyi (Moazzo, 1939)
(Fig. 37), Zafra selasphora (Melvill & Standen, 1901)
(Fig. 38) ou encore Cylichnina girardi (Audouin,
1826) (Fig. 39).
Aux environs du port de Tasucu, les eaux sont plus
profondes (3 à 10 mètres). Le fond est parsemé
d'immenses blocs rocheux. On y retrouve les
spondyles, de taille plus grande (12 à 15 cm) sur
lesquels s’attachent fermement de gros spécimens de
Chama pacifica Broderip, 1834 (Fig. 40) et des
spécimens de Dendrostrea frons (Linnaeus, 1758)
(Fig. 41). Pour cette espèce, on ne dispose d’aucune
information concernant sa présence le long des côtes
du Moyen-Orient (Çeviker, 2001).
A l’est de Tasucu, s’étend une vaste étendue
marécageuse bordée d’une plage de sable fin. Dans les
laisses de mer qui s’y déposent, on retrouve de
nombreux spécimens vides de Rhinoclavis kochi
(Philippi, 1848) (Fig. 42) et quelques rares spécimens
de Pseudominolia nedyma (Melvill, 1897) (Fig. 43) et
de Cerithiopsis pulvis (Issel, 1869) (Fig. 44).
Au-delà de Mersin, on pénètre dans le golfe
d’Iskenderun, bordé à l’ouest par l’embouchure du
fleuve Ceyhan dont les bras forment un très large
delta. En son milieu se situe le port de pêche de
Karatas. De part et d’autre du port s’étendent des
kilomètres de plage de sable fin sur lesquelles se
récoltent de gros spécimens d’Anadara natalensis
(Krauss, 1848) (Fig. 45). A certains endroits
privilégiés se déposent quelques laisses de mer riches
en micro-mollusques: Clathrofenella ferruginea
(Adams A., 1860) (Fig. 46), Finella pupoides Adams
A., 1860 (Fig. 47), Pyrunculus fourierii (Audouin,
1826) (Fig. 48), Monotygma amoena (Adams A.
1851) (Fig. 49) et Monotygma fulva (Adams A., 1851)
(Fig. 50). Ces deux dernières espèces ont récemment
fait l’objet d’une révision (van Aartsen & Hori, 2006)
dans laquelle elles sont respectivement reprises sous
les noms de: Leucotina natalensis Smith, 1910 et
Monotigma lauta (Adams A., 1853).

Les espèces invasives de mollusques en Méditerranée
A l'Est du Delta de Ceyhan, le port, la plage et les
rochers environnants de Yumurtalik sont autant de
lieux propices à de fécondes récoltes. Les filets
abandonnés sur les quais du port sont riches en
Hexaplex pecchiolianus (d’ Ancona, 1871), Muricidae
non-lessepsien endémique du golfe d’Iskenderun
(Houart, 2001). Ceux-ci sont colonisés par de
nombreux spécimens de Gastrochaena cymbium
(Spengler, 1783) qui creusent l’épaisseur du test du
gastéropode (Delongueville & Scaillet, 2005) (Fig.
51). Les Spondylus spinosus également présents dans
les filets proviennent de 20 à 30 mètres de fond et sont
couverts de concrétions parmi lesquelles de nombreux
mollusques lessepsiens (et non-lessepsiens) trouvent
refuge. Un examen attentif d’un lot d’une vingtaine de
Spondylus a révélé la présence de bivalves comme
Brachidontes pharaonis (Fischer P., 1870), Seprifer
forskali Dunker, 1855 (Fig. 52) (Çeviker, 2002b),
Dendrostrea frons (Linnaeus, 1758), Malvufundus
regula (Forskäl, 1775), Chama pacifica Broderip,
1834, Afrocardium richardi (Audouin, 1826) (Fig. 54)
(Delongueville & Scaillet, 2006b) et Gastrochaena
cymbium (Spengler, 1783). Les gastéropodes sont
représentés par Clathrofenella ferruginea (Adams A.,
1860), Finella pupoides Adams A., 1860, Sricteulima
lentiginosa (Adams A. 1861), Ergalatax obscura
Houart 1996, Zafra selasphora (Melvill & Standen
1901), Amathina tricarinata (Linnaeus, 1767) (Fig.
53), Chrysallida fischeri (Hornung & Mermod, 1925)
(Fig. 55) et Pyrunculus fourierii (Audouin, 1826). Ce
"microcosme lessepsien" cohabitait avec dix espèces
de bivalves et huit espèces de gastéropodes de souche
méditerranéenne (Delongueville & Scaillet, 2006c).
L'analyse du contenu stomacal des Astropectinidae
(échinodermes - astéries) est également un moyen très
efficace pour collecter de petites espèces de
mollusques benthiques (Delongueville & Scaillet,
2004a). Un spécimen d’Astropecten irregularis
pentacanthus (Delle Chiage, 1827), prélevé dans le
port de Yumurtalik, contenait dans son estomac de
nombreux individus de Finella pupoides Adams A.,
1860, Syrnola fasciata (Jickeli, 1882) (Fig. 56),
Odostomia lorioli (Hornung & Mermod, 1924) (Fig.
58) et Styloptygma beatrix Melvill, 1911 (Fig. 57). van

mollusques d’origine méditerranéenne faisaient
également partie du régime alimentaire de cette étoile
de mer.
Après avoir dépassé la zone industrielle d’Iskenderun,
la côte du golfe reprend un aspect plus naturel formé
de longues plages de galets entrecoupées de zones
sableuses. À quelques centimètres de profondeur, sous
les pierres ôn retrouve la faune lessepsienne : Diodora
ruppellii (Sowerby G.B. I, 1835), Trochus erythreus
Brocchi, 1821 (Fig. 59), Purpuradusta gracilis notata
(Gill, 1858), Spondylus spinosus Schreibers, 1793 et
Chama pacifica Broderip, 1834.
Au-delà d’Arsuz, la route quitte la côte et rend toute
recherche malacologique impossible en cet endroit.
Une piste pénible traverse la montagne et mène à
"Kale", lieu-dit aujourd’hui inaccessible car englobé
dans une zone militaire interdite d’accès. La chose est
dommage car une exploration antérieure à cet état de
fait avait révélé la présence d’une côte rocheuse
désertique riche en mollusques invasifs comme en
témoigne la collecte de Metaxia bacillum ({ssel, 1869)
(Fig. 60), Cingulina isseli (Tryon, 1886) (Fig. 61),
Acteocina mucronata (Philippi, 1849) (Fig. 62) et
Bulla ampulla Linnaeus, 1758 (Fig. 63).
Au sud de Samandag, port de pêche important que
l’on rejoint par un large détour via l’intérieur des
terres (Antakya), on aboutit à la frontière syrienne et
au début des côtes englobant le littoral de la Syrie et
du Liban. Zibrowius & Bitar (2003) dressent une liste
de quelques espèces invasives récoltées au Liban dont
Murex forskoehli Rüding, 1798 (Fig. 64).
Plus au sud, la côte israélienne se caractérise par une
succession de plages de sable bordées ou non d’un
plateau rocheux. Sur la côte, aux environs de
Shefayim, Cellana rota (Gmelin, 1791) (Fig. 65),
gastéropode patelliforme, est présent en nombre. Il
occupe la niche écologique des patelles absentes en
cet endroit, observation confirmée par Mienis (2002).
Sur le sable, on trouve également des coquilles de
Purpuradusta gracilis notata (Gill, 1858)
(Delongueville & Scaillet, 1989). Une laisse de mer à
Shavei Zion contenait quelques exemplaires d’A/vania
dorbignyi (Audouin, 1826) et de Chrysallida maiae
(Hornung & Mermod, 1924) (Fig. 66). A Caesarea,
une autre laisse de mer renfermait Cerithiopsis
tenthrenois (Melvill, 1896) (Fig. 68).

Les espèces invasives de mollusques en Méditerranée
Des spécimens vivants de Spondylus spinosus et
quelques exemplaires de Chama pacifica peuvent être
observés dans les filets sur les quais du port d’Akko
(pêcheurs - 10 à 20 mètres). La littérature, elle aussi,
témoigne de la richesse des côtes israéliennes en
espèces lessepsiennes (Barash & Danin, 1992 -
Mienis, 2004).
Les côtes d'Israël se prolongent par celles de Palestine
et d'Egypte; elles ont fait l’objet d’un relevé très
complet de la faune malacologique (Barash & Danin,
1992). Sabia conica (Schumacher, 1817) - Alexandrie
(Egypte) - est illustré en Fig. 67.
Au milieu des ces côtes levantines se trouve l’île de
Chypre. Quelques articles (Buzzuro & Greppi, 1997 et
Cecalupo & Quadri, 1994, [1994] 1995, [1995] 1996)
font état de listes de mollusques, notamment
allochtones. Il semble que le pourcentage d’espèces
invasives par rapport aux espèces méditerranéennes y
soit moins élevé que le long des côtes levantines.
Récoltes personnelles : Brachidontes pharaonis -
Paphos, Agia Napa, Pinctada radiata - Bath of
Aphrodite, Trochus erythreus - Paphos, Umbonium
vestiarium - Paphos, Cerithiopsis tenthrenois -
Paphos, Srombus persicus - Agios Georgios, Agia
Napa, Bath of Aphrodite, Cylichnina girardi - Lady’s
Mile Beach.
Les récoltes de Srrombus persicus à Side (Turquie) en
1985 (Delongueville & Scaillet, 1985) et de
Purpuradusta gracilis notata sur le sable de Shavei
Zion (Israël) en 1987 (Delongueville & Scaillet, 1989)
furent à l’origine de notre intérêt pour les espèces
invasives de bivalves et de gastéropodes présents en
Méditerranée.
CONCLUSIONS
Au départ, le sujet semblait simple à couvrir. La
Méditerranée est bien délimitée et ses contacts avec
les mers environnantes sont restreints. Un examen
plus approfondi du sujet rend compte d'une
complexité plus importante, si l’on tient compte des
nombreuses voies d'invasion possibles. Comme
certains mollusques utilisent simultanément ou
successivement plusieurs modes de migration, le suivi
de la colonisation n’en devient que plus difficile.
Enfin, pour certaines espèces de mollusques les voies
d'introduction ne sont pas connues ou sont sujettes à
caution.
Le trafic des navires en provenance de l'Atlantique, de
la mer Noire ou de la mer Rouge croît régulièrement.
Les eaux de ballasts sont les principaux vecteurs du
transport et de l’introduction d’espèces étrangères à la
Méditerranée. Les implantations ne seront réussies que
si les envahisseurs trouvent un milieu favorable dans
la zone de libération. On les retrouve initialement dans
les ports où les purges de ballasts sont le plus souvent
réalisées. Si toutes les conditions favorables
d'implantation sont réunies, il n’est pas rare que les
espèces essaiment de place en place. L’élargissement
66
et l’approfondissement du canal de Suez ne feront
qu'’augmenter le trafic maritime.
Les espèces introduites dans le cadre de l’aquaculture
semblent être assez agressives en termes d’occupation
des niches écologiques méditerranéennes. Cela se
comprend aisément dans la mesure où ces espèces
sont sélectionnées pour s’adapter le plus facilement
possible aux nouvelles conditions locales. Il arrive
aussi que ces implantations s’accompagnent de la
présence d’espèces opportunistes sans valeur
commerciale. Celles-ci ont également des chances de
s’adapter et de faire souche dans leur nouveau milieu.
Il est utile de suivre ces mouvements de population
qui pourraient exercer une influence économique et
induire également une pression artificielle sur les
divers écosystèmes d’origine. La multiplication de ces
zones d’aquaculture est une source croissante
d’expansion des espèces étrangères dans l’ensemble
de la Méditerranée.
Les espèces qui entrent de manière "naturelle" par la
voie du canal de Suez s'installent dans l'est de la
Méditerranée là où les conditions écologiques sont les
plus comparables à celles de la mer Rouge. Ces
espèces lessepsiennes sont extrêmement nombreuses
et constituent la "masse" des envahisseurs répertoriés
en Méditerranée. L’abondance de littérature publiée
sur le sujet en témoigne. Tout le long de la côte
levantine, cet afflux d’espèces nouvelles invasives
s’observe sans aucune difficulté. Un regard posé sous
la surface de l’eau suffit pour convaincre de
l’expansion des espèces lessepsiennes dont certaines
pourraient prendre définitivement la place d’espèces
autochtones. Certains envahisseurs deviennent
aujourd’hui déjà dominant dans le paysage côtier
sous-marin. L'élargissement prévu du canal de Suez
pour 2010 ne fera qu’accentuer ce phénomène
migratoire.
Les changements climatiques en cours, qui réchauffent
les eaux de surface, risquent d’étendre l’aire de
distribution des espèces lessepsiennes vers l’ouest de
la Méditerranée. A quelques exceptions près, les
espèces atlantiques trouvent moins de facilités pour
s’implanter en Méditerranée. La majorité des espèces
invasives est donc d'origine indo-pacifique.
Ce tour d'horizon des espèces invasives de
Méditerranée est loin d’être complet. Il a été
essentiellement réalisé sur base de nos récoltes
personnelles et se doit d’être complété par l'ensemble
de la littérature existante publiée sur le sujet. Un tel
inventaire ne pourra jamais être exhaustif. Les relevés
faunistiques réalisés sur des laisses de mer, sur le
contenu de dragage où sur d’autres substrats révèlent
chaque année l'identification d’espèces invasives
nouvelles. De plus, certaines espèces s'installent ou
disparaissent à l'occasion d'un changement
environnemental de faible ampleur, ou tout
simplement parce que leur établissement était encore
fragile. Enfin, la colonisation par la voie du canal de
Suez est un phénomène dynamique par lequel, à
chaque occasion, de nouvelles espèces ont la chance

KEY WORDS. Bivalvia, Cardiidae, Philippines, Acrosterigma suduirauti, n. sp.
ABSTRACT. Acrosterigma suduirauti n. sp. is described from shells originating from the
Philippines. It belongs to the species group of À. uniornatum Vidal, 1999 and is especially close to
A. profundum Vidal, 1999, with which it is compared. It differs mainly by the nature of the rib
sculpture, the outline, the colouration and the geographic distribution.
INTRODUCTION
In his review of the ‘elongated cockles’ Vidal (1999)
formulated several different species groups with
shared characters. One of these is the group of
Acrosterigma uniornatum Vidal, 1999, including four
Recent species and one fossil. The following main
characters unite the taxa of this group:
e moderately pointed, ovoid and equilateral shell:
e well marked and delineated, slightly hollowed
lunula;
moderately angled hinge with cardinals slightly
connected in the right valve:
e ribs on posterior quarter bearing long thin scales,
regularly obliquely placed.
The recent discovery in the Philippines of another
extant species confirms the validity of this grouping.
Another ecological character of this group is
confirmed too: these species live in relatively deep
water for Cardiidae, mainly from about 100 m to more
than 500 m. They are all characterized and separated
from other Acrosterigma species by the particular rib
morphology of the posterior part of the shell, with ribs
bearing regularly disposed parallel straight oblique
scales, and by the progressive extension of this
ornamentation more or less far into the median-
posterior part, lacking any sharp contrast between the
posterior slope and the rest of the shell (figs 11-12).
Another observed constant peculiarity is the partial
connection of the cardinals in the right valve, a feature
never observed in other species groups in
Acrosterigma or the related Vasticardium. The various
species of the À. uniornatum group can be separated
one from another by the number of ribs and the
secondary ornamentation of the ribs in the median part
of the shell.

MATERIAL AND METHODS
The type series consists of four paired valves; in
addition four supplementary paired valves were
studied from private collections.
Measurements: H — Height, the longest distance from
the umbo to the ventral margin; L — Length, measured
parallel to the hinge; W — Width, or maximum

As far as methods of identification are concerned, we
must underline the importance of the rib morphology
(structure and ornamentation of the ribs).

collected (Figs 1-3); paratype 1 MHNBx 2007.TY.1,
same sample as holotype (Fig. 4); paratype 2 ZMA
Moll. 407.009, Bohol, Balicasag Isl., tangle nets,
depth 80-150 m, 10.2006; paratype 3 TP 3220, same
sample as paratype 2 (Fig. 6).
Other material examined. Philippines, Bohol,
Balicasag Isl., 06.2004. (coll. HD 14267, 1 p.v.);
Mindanao, Balut Isl., by tangle nets, deep sea. (coll.
SH, 2 p.v., fig. 5); Talikud Isl. 06°56'N-125°41'E, near
Davao, with tangle nets, collected by fishermen,
01/02.2006 (coll. TP 3009, I p.v.).
Description. Shell of medium size (holotype H 37.8
mm: largest specimen observed), relatively thin-
shelled, slightly elongated (mean L/H — 0.835, range
0.80-0.86, n — 8): appreciably tumid (mean W/L —
0.814, 0.80-0.84, n — 8); rather quadrate, with a
straightening of the posterior and anterior margin,
both occasionally even slightly concave (paratype 2).
Lunula small, white, identical on both valves, almost
flat, except for slight raising of the margins besides
umbo.
Colouration: externally whitish or vyellowish with
irregular red-brownish stains, predominantly on
median-posterior part, disappearing in adult marginal
zones; posterior slope remaining entirely pinkish
brown or orange yellow. Internally, pink stains
homologous of exterior ones, gradually diminishing
towards margins.
Hinge appreciably asymmetrical with anterior laterals
more distant from cardinals than posterior laterals.
Cardinal teeth the right valve joined at their base.
Mean rib number: 60.75, range 55-65, n — &.
Rib morphology: posterior slope with about 10 ribs,
flat, divided into two parts: posterior half ornamented
with regularly disposed small oblique scales; anterior
half smooth. Interstices very thin. In addition, ribs
divided by longitudinal furrow situated below scales.
Figures 1-11
In the median-posterior quarter ribs become
progressively more raised, with an asymmetrical
trapezoidal profile with three parts: a higher posterior
flank with same scales as on posterior slope; a smooth
flat top zone slightly sloping onwards; a very short
anterior flank generally smooth but occasionally, by
places, with irregular very oblique diffuse long scales,
present too on the posterior slope, but more tubercular.
Top furrow observed on most posterior ribs remains
present, separating posterior flank from top zone: this
furrow progressively disappears onwards. On anterior
half of shell ribs become more rounded and scales
change progressively into commarginal ridges
encroaching upon whole surface of ribs.
Range and habitat. Only known from the
Philippines. Collected at depths between 80-150 m.
Remarks. Acrosterigma suduirauti mainly differs by
the different rib number (55-65) from the other extant
members of its species group viz. À. uniornatum
Vidal, 1999 (36-43 ribs); À. suluanum Vidal, 1999
(40-45 ribs); À. amirante Vidal, 1999 (52-55 ribs) and
A. profundum Vidal, 1999 (55-63 ribs, Figs 7-10, 12).
The latter is clearly its closest congener. 4. suduirauti
can be differentiated from this species by a more
quadrate shape, a thinner, slightly less elongated shell
and by the very poor development of the secondary
serrations on the anterior flank of the ribs (Fig. 11),
while on 4. profundum (Fig. 12) they are numerous,
constant and nearly as well developed as those on the
posterior rib flanks. Besides, it has a different
distribution and known so far only from the
Philippines, whereas 4. profundum is known from
New Caledonia, Marshall Islands (both Vidal, 1999)
and Indonesia, Flores Sea (coll. TP 2923, Fig. 9-10).
Finally, within the restrictions of the limited material
of both species available, À. suduirauti appears to
have more yellow elements in its colouration, in some
cases limited to the posterior margin, sometimes
covering the whole shell (Fig. 5). The red-brownish
stains do not extend to the anterior margin, which does
occur on À. profundum (Fig. 9).

Scaphella (Scaphella) garciai n.sp.
(Gastropoda: Volutidae: Scaphellinae)
a new volute from off Yucatan, Mexico

KEY WORDS. Gastropoda, Scaphella, Volutidae, new species, Yucatan, Mexico.
ABSTRACT. Scaphella (Scaphella) garciai n. sp. is described on the basis of two specimens, one
collected off San Augustine, Florida. Differences between the new species and its congeners are
established.
INTRODUCTION
Recently checking his collection, Emilio Fabiän
Garcia pointed out to me a specimen of the genus
Scaphella Which seemed to be a previously
undescribed species. The specimen was given to him
by Edith Mugridge, a well-known dealer and shell
collector from Sanibel Island, Florida. Ms. Mugridge
obtained many of her specimens from a number of
shrimpers who worked the east coast of Florida and
the Yucatan waters, and the true locality of the
specimen in question became uncertain.
Taxonomic placement (in Bail & Shelton, 2001)
The genus Scaphella comprises several related
polytypic taxa, which have been the subject of
controversial classification at both the generic and
specific ranks.
Based upon the shape of the radula, Pilsbry & Olsson
(1953) split Scaphella into three genera:
-Scaphella s.s. With but a single long narrow cusp;
-Clenchina With a conic central cusp, flanked by two
minute accessory cusps (synonym Rehderia Clench,
1946);
-Aurinia H. & A. Adams, 1853 with a pointed central
cusp and two well-developed side cusps.
Weaver & du Pont (1970) and Bayer (1971)
downgraded those three genera to a subgeneric rank
of Scaphella, pointing out the minor taxonomic
significance of their radular difference, especially
between Clenchina and Scaphella s.s., both of which
are now considered synonyms.
Though relegated into synonymy of Scaphella by
Emerson & Old, jr. (1979) and Poppe & Goto (1992),
the subgenus Aurinia deserves to keep its subspecific
status: a chief feature, emphasized by Pilsbry &
Olsson, is the thin callus covering the ventral side of
the shell, often incrusting a muddy deposit.
Additional characters such as a complete tricuspidate
radula, light structure of the shell, lack of fasciole,
obsolete columellar plaits, and open pattern of
irregularly spaced dots are sufficient to maintain the
polytypic Scaphella dubia (Broderip, 1827) in its
subgeneric status.
On the contrary, Scaphella s.s. includes species with a
strong shell, a more or less pronounced fasciole, 2 to
4 well-defined columellar plaits, mostly a dense spiral
pattern of dots or bands, and a Y-shaped radula with
or without vestigial side cups.
Based upon these shell characters only, Scaphella
garciai can be temporarily placed into Scaphella s.s.,
pending additional anatomical information.

Scaphella garciai n.sp.
entirely sculptured with numerous thin spiral cords
(ca. 30-35 on penultimate whorl) crossed by light
growth striae, giving faint reticulated appearance,
weakening on dorsum of last whorl (Fig. 14). Suture
adpressed, underlined by subsutural constriction
forming well-marked concave ramp. Aperture
narrow, elongated, occupying 0.60 % of total shell
length. Outer lip thin, rapidly thickening below.
Columella straight, with three thin plicae; adapical
plica strongest (Fig.13). Siphonal canal narrow,
tapered. Fasciole 1ll-defined. Shell coloration
vellowish-ivory without pattern.
Animal and radula unknown.
Comparison. In overall shell characters, the most
similar species to Scaphella garciai is Scaphella
(Scaphella) gouldiana (Dall, 1889), which has the
same nuclear structure and same spiral threads.
However, S. gouldiana has a broader ovate shell with
a short spire bearing 21-24 solid nodules; its
protoconch is slighty more elevated, the spiral
sculpture on the body whorl is weaker, and the
subsutural band is flat and hardly distinguishable.
Two equal plicae plus an abapical smaller and the
presence of a pattern of spiral brown bands in S.
gouldiana precludes also any confusion (Figs 8-9).
A still undescribed small-sized Scaphella from deep
water off Key West, close to S. gouldiana shares with
S. garciai the same protoconch shape and, on the
body whorl, the same spiral sculpture and lack of
pattern. However, its smaller size (average length
under 40 mm), strongly angled whorls, short
triangular spire bearing a spiral row of prominent
axial nodules extending onto the first two-third of the
body whorl, and four, strongly developed columellar
plaits are quite different (Dickson, 1996) (Figs 10-
11).
Scaphella neptunia (Clench & Aguayo, 1946) is a
small species with a somewhat similar outline, but it
differs by having a larger protoconch bearing a
prominent calcarella, a shorter spire with one less
whorl, a body whorl with strong spiral grooves and a
pattern of spiral rows of brownish axial dashes (Figs
6-7).
Etymology. This species is named for Emilio Fabiän
Garcia, the well-known conchologist who first drew
attention to this taxon, and who has donated the
Figures 1-11
1-5. Scaphella (Scaphella) garcia n.sp.
holotype to the Academy of Natural Sciences of
Philadelphia (ANSP).
Remarks. The first occurence of this taxon in
literature has been pictured by K. & L. Sunderland
(1992) but misidentified as Scaphella aguayoi
(Clench, 1940). This shell, selected as paratype, was
dredged from 260 meters by Ted Yocius off St.
Augustine, FL in 1971. The holotype was labelled off
Contoy Light, Yucatan, 200 m deep. However, after
later investigations, no fishermen operating in the
Yucatan waters have ever seen this shell. This
location seems erroneous all the more that the overall
characters of S. garciai are closer to Florida
Scaphella than to the known Yucatan species (S.
contoyensis Emerson & Old, Jr, 1979 and S.
macginnorum Garcia & Emerson,1987).

Claude Vilvens : La phylogénie actuelle des Mollusques
Les dernières découvertes portant sur l'analyse d'ADN ont amené les biologistes à revoir profondément
la classification du vivant durant ces dernières années. L'approche cladistique prend à présent en compte ces
nouvelles informations et conduit à des phylogénies fort éclairantes. Notre Vice-président se propose ici de nous
brosser un tableau général de la situation et, bien sûr, de s'intéresser de plus près aux branches de l'Arbre de la
Vie qui concerne les Mollusques : du Cambrien aux temps actuels, voici bien des créatures à rencontrer !
La tradition sera aussi respectée, puisque la première réunion après les grandes vacances est celle de
l'événement gastronomique de septembre. Pour entamer la rentrée dans la bonne humeur et nous raconter nos
folles aventures de vacances (notamment celles du Président ou du Vice-président — un must !), nous vous
proposons en effet de nous retrouver au traditionnel
banquet annuel de la SBM
qui débutera à 19h (voir annonce page 67 pour les détails).

MOTS CLEFS. Mollusques, bois immergé, Islande.
KEY WORDS. Molluscs, submersed wood, Iceland.
RESUME. Sur un échantillon de bois immergé, trouvé à Njardvik (port du sud-ouest de l’Islande), trois espèces
de mollusques ont été récoltées: Coccopigya spinigera (Jeffreys, 1883), Idas argentea Jeffreys, 1876 et 1das sp.
ABSTRACT. On a sample of submersed wood, found at Njardvik (harbour of South-West Iceland), three
species of molluscs have been collected: Coccopigya spinigera (Jeffreys, 1883), 1das argentea Jeffreys, 1876
and /das sp.
INTRODUCTION
Un certain nombre de mollusques utilisent comme support des substrats organiques immergés. Il peut s’agir,
entre autres, de bois coulés dérivants, d’os de différents cétacés et de poissons ou même de fruits. Souvent, les
bois sont perforés par des bivalves de la famille des Teredinidae ou de celle des Xylophagidae.
Ainsi, de petits gastéropodes du groupe des Archeogastropoda ont été isolés sur des substrats organiques
immergés (Dantart & Luque, 1994). Ils appartiennent, entre autres, aux familles des Cocculinidae [Coccopygya
lata Warén, 1996, C. spinigera (Jeffreys, 1883), C. viminensis (Rocchini, 1990)] et des Pseudococculinidae
{[Copulabyssia corrugata (Jeffrey, 1883)|].
Des Mytilidae ont également été récoltés sur différents substrats organiques et actuellement cinq espèces d’/das
sont répertoriées pour l’Europe (Warén 1991 et 1993): Z. argentea Jeffreys, 1876, I. ghisottii Warén & Carrozza,
1990, Z. modiolaeformis (Sturany, 1896), I. pelagica (= dalmasi) (Forbes in Woodward, 1854) et I. simpsoni
(Marshall, 1900).
RECOLTES PERSONNELLES
Une pièce de bois immergé a été récoltée à Njardvik, port du sud-ouest de l’Islande, le 30 juillet 2006 (Fig. 1).
Elle avait été fraîchement pêchée et était déposée sur le quai du port. Ce morceau de bois creusé par des tarets
mesurait environ 1 mètre de long pour un diamètre de quelques 30 centimètres. Malheureusement, aucune
information précise n’a pu être obtenue concernant le lieu de prélèvement (localisation exacte et profondeur).
Cependant, en tenant compte du type de bateaux relâchant à Njardvik en cette époque de l’année, tout porte à
croire qu’il s’agirait d’une collecte réalisée fort probablement au sud-ouest de l’Islande.
De petits gastéropodes de la famille des Cocculinidae (L: 5,6 mm x 1: 3,9 mm x h: 2,9 mm pour le plus grand
d’entre eux), encore remplis de parties molles, collaient à la surface du substrat. Il s’agissait de spécimens de
Coccopigya spinigera (Jeffreys, 1883) (Fig. 3 et 5) dont le périostracum, garni çà et là de longues soies, était
bien conservé. D’autres spécimens vides étaient emprisonnés dans le sédiment remplissant quelques unes des
galeries de tarets encore garnies de leur tube de calcaire blanc (Fig. 2). Au total, quelques 36 individus ont été
récoltés. L’espèce est particulièrement bien illustrée par Warén (1991) et Dantart & Luque (1994). Distribution:
nord-ouest de l’ Atlantique (Virginie), Islande, entre les îles Féroé et les Hébrides et Méditerranée occidentale.
Il fut également possible d’identifier la présence d’une autre espèce de mollusques. Plus de trente spécimens
d’un petit bivalve de la famille des Mytilidae étaient attachés à la surface des galeries creusées dans le bois. II
s’agissait de /das argentea Jeffreys, 1876 (Fig. 4). Le plus grand des individus mesurait 9,7 mm de long, les
autres ne dépassaient guère la longueur de 6 à 7 mm. L’espèce est illustrée par Warén (1991). Distribution: nord-
ouest de l’Atlantique (Virginie et Massachusetts), sud de l’Islande et au large du Portugal.
NovareEx / Société 8(2), 10 juin 2007 69
Un autre bivalve de la même famille, beaucoup plus grand que les précédents (+/- 20 mm s’il avait été entier),
Idas sp. probablement Z. simpsoni (Marshall, 1900) (Fig. 6) avait pour sa part été écrasé lors de la manipulation
de la pièce de bois. Ce spécimen était le seul de son espèce présent sur le bois immergé. Illustrations de J.
simpsoni dans Warén & Carrozza (1990) et dans Warén (1991). Distribution: sud de l’Islande, Mer du Nord
jusqu’à la Méditerranée.
Quant aux tarets (Teredinidae) responsables de la grande fragilisation de la pièce de bois, il n’a pas été possible
d’en identifier la ou les espèces, faute d’avoir pu en extraire le moindre spécimen.
CONCLUSION
Un examen attentif de tout substrat organique ayant séjourné au fond des eaux marines permet de récolter de
petits mollusques inféodés à ce type de support. La collecte faite à Njardvik de Coccopigya spinigera, et d’Idas
argentea est conforme aux aires de distribution relevées dans la littérature.
NOTE
La nomenclature des mollusques est reprise de CLEMAM, « Check List of European Marine Mollusca »
www.somali.asso.fr/clemam/index.clemam.html (consultation: 15 avril 2007).
REMERCIEMENTS
Nous remercions Anders Warén pour les échanges d’informations concernant le genre /das en Europe.

L'Assemblée Générale de la Société Belge de Malacologie
du 10 février 2007
Roland HOUART, Claude VILVENS, Etienne MEULEMAN et Annie LANGLEIT.
\ Conformément aux statuts de la Société Belge de Malacologie, nous nous sommes réunis le
10 février 2007 lors de notre assemblée générale pour jeter un regard critique vers nos réalisations passées et
vers nos prévisions pour 2007 et vers 2008 pour les cotisations. Les points suivants ont été discutés lors de cette
assemblée :
1. RAPPORT MORAL, avec un compte-rendu de nos réunions, de nos excursions, de nos publications, des
membres, du conseil d'administration, du site Web, de la bibliothèque et de notre journée anniversaire du 25
novembre.
2. RAPPORT FINANCIER.
3. ELECTIONS
4. COTISATIONS 2008.
5. DIVERS.
L'exposé était soutenu par une présentation Powerpoint retraçant les aventures de Rolanlysse, personnage
mythique au destin épique protégé par Athéclauda ;-) …
1. RAPPORT MORAL
1.1 Nos réunions
En 2006 Nous nous sommes retrouvés 9 fois pour suivre des conférences; une fois lors de notre journée
anniversaire et 2 fois au cours d'excursions.
- Le 14 janvier 2006 nous présentions la 20me exposition de coquillages réalisée par les membres de la SBM.
Ces expos sont fidèlement relatées et illustrées dans Novapex/Société.
NOVAPEX / Société 8(2), 10 juin 2007
- L'Assemblée Générale du 4 février nous a permis de faire le point sur ce qui avait bien ou moins bien
fonctionné en 200$. Un verre symbolisant les 40 ans de la SBM avait été offert à tous les membres présents.
- Le 18 février, David Monsecour nous présentait la famille des Angariidae.
- Le 25 mars, Etienne Meuleman nous fit rêver en nous promenant sur les côtes de la Floride.
- Quelques semaines plus tard, le 22 avril, Jacques et Rita Senders nous emmenaient à Bali et Lombok.
- Le samedi 17 juin Marcel Verhaeghe nous a fait partager quelques-uns de ces moments privilégiés de son
dernier périple: Tokyo, Hong-Kong et Australie.
- Le 9 septembre nous avons organisé une réunion collégiale ou chacun pouvait présenter des coquilles qui en
rappelaient d'autres. |
- Le samedi 14 octobre nous organisions Fata Conchylia. Jeu qui consistait à reproduire fidèlement et en
grandeur nature un tableau du 18me siècle. Le compte-rendu de cette réunion est paru dans Novapex-Société
Vol. 7 (4).
-le samedi 25 novembre nous vit tous réunis à l'IRSNB pour fêter dignement nos 40 années d'existence (voir
plus loin).
- Nos réunions de 2006 se terminèrent le 16 décembre, lorsque Sophie Valtat nous proposa un panorama général
des mollusques pélagiques.
Comme je n'ai pas changé d'avis, je vais devoir me répéter : ces réunions sont une occasion de
rencontres, mais elles nous offrent également l'opportunité d'échanger des idées, des nouvelles, des impressions,
et de s'offrir, en plus, le ou les coquillages recherchés! En outre, que ce soient les réunions consacrées aux
relations de voyages ou à l'étude d'un groupe, d'une famille, ou encore à la présentation d'un autre sujet, les
conférenciers sont tous passionnants et nous permettent de parfaire nos connaissances dans différents domaines.
De plus, l'ambiance y est excellente: derniers potins, commentaires sur les dernières trouvailles ou acquisitions
récentes. découvertes de nouvelles coquilles pour sa collection... échanges... achats. identification.
présentation des acquisitions récentes pour la bibliothèque. tout y passe. tout se voit. tout se raconte.
Si vous assistez à nos réunions, continuez à nous rendre visite, si vous n'êtes jamais venus, de grâce,
essayez avant de dire que de toute façon c'est trop compliqué, que rouler dans Bruxelles n'est pas une sinécure,
que la langue utilisée est un obstacle, que nous sommes trop savants.
Nous parlons (presque) tous français, néerlandais et anglais sans trop de problèmes, rouler dans Bruxelles le
samedi n'est vraiment pas trop compliqué (quoique pour l'instant des travaux nous obligent à effectuer un
détour), et si vous êtes débutants, dites-vous bien que tout le monde est parti de là et que l'ambiance qui règne ici
apaisera très vite vos craintes. Alors venez nous rendre visite !

1.2 Nos excursions
Les excursions de la SBM sont nos "travaux pratiques" sur le terrain. Elles
permettent d'évaluer ponctuellement la biodiversité (terme à la mode !) de nos Mollusques
Terrestres et Dulcicoles autochtones. Cette année, nous avons parcouru des sites de la
province de Liège, que Claude et Etienne connaissent particulièrement bien. Deux
excursions se sont déroulées en 2006 :
a 1) L'excursion de printemps du 27 mai 2006 nous a fait parcourir deux sites de Basse
Meuse, Die particulièrement de la région de Visé :
+ Le thier de Caster, sur la commune de Petit-Lanaye; cette colline boisée s'est révélée très intéressante du
point de vue malacologique, avec des rochers humides et des troncs d'arbres appréciés des Mollusques.
+ Le Cannerbos, colline boisée située aux Pays-Bas, près de la commune belge de Kanne, qui possède autour
de son château Neercanne un bois aménagé sur le Cannerbers; cette fois, il a fallu se montrer patient pour
trouver des Terrestres, mais nous y sommes parvenus; en particulier, nous avons découvert une petite maison
forestière couverte d'Helix pomatia !
2) L'excursion d'automne a eu lieu le 30 septembre 2006 dans la région de la Vallée de l’Ourthe, plus
précisément à Chanxhe, Comblain-au-Pont et Tilff; Cette région est bien connue pour ses paysages escarpés et
s'est révélée très intéressante pour les malacologues amateurs de Terrestres : plus d’une vingtaine d’espèces
furent récoltées au cours de la journée.
L3 Nos publications : Novapex
Quatre numéros, dont un numéro HORS SERIE et un double ont vu le jour. Comme les autres années
les auteurs furent variés et les articles très intéressants. Jugez-en par vous-mêmes:
Le Volume 7 de Novapex a totalisé 116 pages pour les numéros ordinaires et 31 pages pour le numéro Hors
Série, soit un total général de 147 pages. Le numéro Hors série de NOVAPEX était consacré à la description de
11 nouvelles espèces de Cystiscidae du Pacifique, par Andrew Wakefield et Tony McCleery. Les numéros
ordinaires ont rassemblés 16 articles des auteurs suivants: Philippe Maestrati, Luis Riccardo Lopes de Simone,
Adolpho Birman, Mitsuo Chino, Emilio Rolan, Franck Boyer, Christiane Delongueville, Roland Scaillet, Koen
Fraussen, Emilio Rolan, Roland Hadorn, Juan Trigo, Constantine Mifsud, Paul Sammut et vos serviteurs, Roland
Houart et Claude Vilvens. Les familles abordées étaient variées comme d'habitude : Calliostomatidae, Trochidae,
Conidae, Muricidae, Columbellidae, Mytilidae, Buccinidae, Chilodontidae, Turritellidae, Marginellidae et
Cystiscidae se sont partagés les 147 pages. Pas moins de 46 espèces nouvelles ont été décrites. Ces articles ont
également comportés un total de 11 planches photos en couleur et de nombreuses planches noir et blanc.
1.4 Nos publications : Novapex/Societe
Sur un total de 175 pages (170 l'année dernière) dans 4 fascicules, le magazine généraliste de la SBM
nous à Proposé :
a) les rubriques habituelles mais tellement importantes: "Prochaines activités", "Quoi de neuf ?", "Quelques
nouvelles publications", "Nous avons reçu", "Morceaux choisis" et "L'écho des réunions". Pour ces derniers,
particulièrement intéressant en ce sens que tout le monde contribue :

On peut donc constater que Novapex/Société 2006 a encore une fois été l'œuvre de beaucoup de monde.
Un grand merci à tous ! Mais inutile de dire que tous les articles à sujet malacologique sont les bienvenus © !
1.5 Conseil d'administration
Que voulez-vous que j'ajoute à ce que je dis les autres années au sujet du conseil d'administration ?
Sinon que, comme tous les ans, je voudrais encore une fois remercier ces travailleurs de l'ombre pour leurs
prestations sur des sujets parfois peu attrayants et assez rébarbatifs, bien que nécessaires!
Cette année fut également une année chargée pour nous à cause de notre 40me anniversaire! D'autre
part, nous ne pouvions quand même pas laisser passer cet anniversaire sans réagir ! Je dois aussi ajouter que pour
le 40me nous avons eu la participation active de M. Ralph Duchamps que nous remercions encore aujourd'hui.
N'empêche, ce fut un très gros travail qui nous a valu de nombreuses heures de discussions !
Par la même occasion, je voudrais encore vivement rappeler que toute personne désirant faire partie de
ce comité est évidemment le bienvenu. Il n'y a pas de condition, sinon celle de faire partie de la Société en tant
que membre ordinaire, et bien sûr, de passer par les élections. il y aura du travail pour tous !

Nous comptions 140 membres effectifs en ordre de cotisation pour 2006 dont une douzaine
d'institutions (sans compter les membres familiaux), dont 58 en Belgique, 48 en Europe (au sens large) et 34
hors Europe. Ces chiffres reflètent la stabilité devenue habituelle depuis des années. De nouveaux membres sont
déjà inscrits pour 2007 !
Après le contrôle de l'année précédente quant à l'intérêt de certains échanges, nous comptions, en 2006,
37 échanges.
1.7 Le site web
Notre site (http://www.sbm.be.tf) a fait peau neuve mais ce n'est que cosmétique : il reste, avec sa
soixantaine de pages html agrémentées de nombreuses photos :
+ un fournisseur d'informations, générales (présentation de la SBM, de ses contacts, présentation de la
malacologie, dates des grandes marées) et plus pratiques (agenda des réunions et excursions, annonce et
informations pratiques pour les
excursions, aspects divers de la
vie de la société, table des
matières de Novapex par
auteurs),
+ mais aussi une référence
didactique (index des articles de
Novapex depuis sa création,
dictionnaire de malacologie en
français, bibliographies de
malacologues célèbres,
description d'expéditions
maritimes célèbres ainsi que
nombreux liens utiles.
NovaPeEx / Société 8(2), 10 juin 2007
1.8 La bibliothèque

1.9 La fête anniversaire des 40 ans de la SBM
Je pense qu'il n'y a pas grand-chose à ajouter au compte-rendu paru dans le Novapex/Société du 10
Mars 2007. Nous aimerions cependant combler un oubli dans ce compte-rendu. En effet, en citant les visiteurs
étrangers nous avons omis de citer (bien involontairement) Paolo CROVATO), secrétaire de La Societa Italiana
di Malacologia qui nous accompagna durant toute l'après-midi.
Bon
nombre de naturalistes eurent ainsi l'occasion de
découvrir 1 monde de ta malacologie, souvent mal
connu d
$S amateurs d'omithologie ou de botanique

3. ELECTIONS
Personne ne devant se représenter cette année, tout reste comme avant étant donné que nous n'avons pas
non plus enregistré de démission.
4. COTISATIONS 2008
Les cotisations sont restées inchangées depuis janvier 2003. Pendant 5 ans nous avons donc payé 35
euros pour les membres habitant la Belgique et 50 euros pour les membres habitant l'étranger. En cinq ans
pourtant nous en avons connues des améliorations et des planches couleurs supplémentaires et de meilleures
qualités. Les factures de l'imprimeur ont ipso-facto également été améliorées et revues à la hausse (ce qui est tout
à fait normal lorsque l'on sait qu'une planche couleur coûte l'équivalent de 280 euros).
Pourtant, et ceci en partie grâce au subside alloué par le Lotto et la région wallonne d'abord, ensuite par la région
wallonne seule, nous n'avons pas dû augmenter la cotisation. La balance de nos entrées et de nos dépenses est
restée en équilibre pendant 5 ans.
Malheureusement, cette année le subside alloué par la région wallonne a été diminué, sans raison
apparente. Ceci ajouté aux frais d'envoi, car là aussi en 5 ans nous avons subi quelques augmentations, et aux
rentrées moins importantes, nous mène cette année à un déficit budgétaire de plus de 1000 euros (voir le rapport
financier). Pour 2008 l'alternative suivante a été proposée:
Nous proposons une augmentation de 5 euros pour les cotisations et les abonnements, soit une
cotisation de 40 euros pour la Belgique et 55 euros pour l'étranger à partir de janvier 2008 SI et seulement SI
nous nous apercevons qu'au cours de l'année 2007 nos subsides n'augmentent pas ou si nos finances plongent
encore plus bas. Car si nos finances ne connaissent plus de baisse, la situation s'améliorera automatiquement et
ne nécessitera plus d'augmentation de la cotisation.
Nous en saurons sans doute plus en septembre 2007. Nous vous proposons donc cette alternative : si à la
date du 1” septembre 2007 nous nous apercevons que notre budget est encore déficitaire nous augmenterons les
cotisations et les abonnements de 5 euros à partir de janvier 2008.
Cette proposition a été acceptée par un vote à main levée.
5. DIVERS
C'est devenu une tradition : l'AG se termine apr un ptite cadeau pour tous les membres présents. Cette
année, comme les réveillons n'étaient pas encore très loin, nous avons offert à chaun une bougie en forme de
coquillage présentée sur un plateau décoré d'autres coquillages. Gageons que bien peu brûleront réellement leur
bougie ;-) !
Comme tous les ans un verre de l'amitié a clôturé cette Assemblée Générale.
En fin de journée, les membres du comité se sont réunis pour élire Président, vice-président, secrétaire et
trésorière.
MERCI A TOUS d'être venu nous soutenir lors de cette Assemblée Générale !
Merci du fond du cœur !

L'écho des réunions
Etienne MEULEMAN
Réunion du 3 mars 2007 (EM) Annie Langleit : Les Tellinidae : la sous famille des
Tellininae (suite).
Notre spécialiste des bivalves, nous a présenté la suite de son
étude sur la famille des Tellinidae. Elle avait choisi de nous parler du
sous-genre Tellinella Môürch, 1853.
Après un rapide rappel sur les caractères généraux de cette
belle famille (charnières, dents, sinus palléal), notre oratrice a plongé
dans le vif du sujet en nous expliquant les caractères distinctifs du
sous-genre étudié. Elle n’a pas oublié de nous énumérer les multiples
synonymes présents dans la littérature.
Par la suite, nous avons pu
découvrir les quelques 25 espèces
constituant le sous-genre. Pour
chacune d’elle, nous avons eu droit à
une description sommaire et à une
présentation de la coquille. Il y en
avait des rares et des moins rares, des
grandes et des moins grandes, avec
des sculptures bombées, anguleuses,
lamelleuses ou écailleuses,.… bref,
nous en avons eu pour notre argent.
Merci à Annie pour ce travail de
préparation fastidieux et sa
présentation plaisante. À quand la
suite ?

There will also be a contributed papers session and a poster session, with posters on display throughout the
conference. The conference will start with an « icebreaker » on Sunday late afternoon, 15 July 2007. The
scientific presentations are organised in four parallel sessions on Monday, Tuesday, Thursday and Friday.
During the poster presentation on Tuesday evening there will be a reception with wine, typical Belgian |
degustations, cheese and of course. a selection of Belgian beers. On Thursday evening AMS will host its |
annual auction of molluscan books and paraphernalia (no specimens) to benefit its student programs. The |
conference dinner will be on Friday evening (several options are still being considered). Wednesday is a free day
during which participants can discover the many historical and beautiful places in Antwerp. They can also join
one of the suggested congress activities or do whatever they want, of course !

Les animaux étranges du bord de mer
par M. Loir
pp. 1-32, 75 photos couleur. Format: 192 x 258 mm, couverture souple.
Prix: 6.07 EUR. Editeur: Ouest-Fance, Rennes, 2007
Ce petit fascicule appartient à la même famille
("Découverte nature" chez Ouest-France) qu'un autre ouvrage
présenté dans ces colonnes il y a quelques temps, à savoir "Les
coquillages des côtes françaises" de P. Bouchet et R. von
Cosel. Cette fois, dans un format un peu plus grand et signé par
M. Loir, ancien directeur de recherches à l'INRA de Renens, il
s'agit d'une présentation générale des Invertébrés marins,
appuyée par de magnifiques photos en couleur.
La première partie présente les groupes principaux,
avec des exemples d'organismes et un schéma très clair de
l'organisation anatomique de ces animaux. Sont ainsi présentés
de manière très accessible Eponges, Cnidaires (Méduses et
Anémones), Bryozaires (petits organismes vivant dans des
loges calcaires), Vers, Crustacés, Echinodermes (Etoiles de
mer et Oursins), Ascidies et bien sûr Mollusques.
La seconde partie s'intéresse aux mœurs de ces
animaux et aux faits caractéristiques de leur éthologie : modes
de reproduction, vie en colonie, symbioses, description plus
détaillée de certains organismes (comme les Gorgones, les
Hydraires, les Crustacés décapodes ou les Nudibranches) et
finalement les différents modes d'alimentation (végétariens,
filtreurs, détritivores, limivores et carnivores comme les Etoiles
de mer et les Nudibranches mangeurs d'Eponges et de
Cnidaires).
Ce petit livre est une petite merveille et, en plus, comme de coutume chez Ouest-France, il ne coûte pas
cher : je l'ai payé un peu plus de 6 EUR (non, on ne me l'a pas donné pour que j'ne dise du bien ;-)). Certes, on
parle un peu des Mollusques et beaucoup des animaux qui partagent leur milieu de vie : mais ce serait dommage
de s'en priver !

ABSTRACT. In the present paper we describe the new genus Amiantofusus gen. nov. to
accommodate the Atlantic species Fusus amiantus Dall, 1889. The genus belongs to Fasciolariidae
and this family is confirmed as distinct from Buccinidae, based on anatomical differences. We add
an Indo-West Pacific fauna of seven species described as new to science: Amiantofusus pacificus
sp. nov. (North Fiji Basin, New Caledonia, southern Coral Sea, south West Pacific), À.
gloriabundus sp. nov. (North Fiji Basin, Vitiaz Zone), À. sebalis sp. nov. (New Caledonia, Loyalty
Islands, Vanuatu), 4. candoris sp. nov. (Chesterfield Islands, Fairway), À. maestratii sp. nov.
(New Caledonia), À. borbonica sp. nov. (Reunion) and À. cartilago sp. nov. (Mozambique
Channel). In addition we add two unnamed species: 4. species 1 (North Fiji Basin) and 4. species
2 (Vanuatu). Fusus thielei Schepman, 1911 is briefly discussed, the generic placement is still

INTRODUCTION
Recent deep-sea biodiversity exploration in the South
Pacific by Institut de Recherche pour le
Développement (IRD, Nouméa, formerly ORSTOM)
and Muséum national d'Histoire naturelle (MNHEN,
Paris) has brought to light many hundreds of new or
little known species of molluses and other benthic
invertebrates. As a result of these expeditions, over
400 new species of molluscs have been described
from the deep waters off New Caledonia alone (see,
among others, Crosnier & Bouchet 1991 and Bouchet
& Marshall 2001). Also the Buccinidae and
Fasciolariidae are well represented in this rich
material. Results on the genus Fusinus from these
expeditions has been presented in a paper dealing
with the deeper water species of the subgenus
Chryseofusus (Hadorn & Fraussen, 2003). The genus
Granulifusus has been confirmed as being distinct
from typical Fusinus and the species collected by
these expeditions are presented in a second paper
(Hadorn & Fraussen, 2005). The subgenus Fusinus is
discussed in two subsequent papers (Snyder &
Hadorn, 2006 and Hadorn & Fraussen, 2006).
The fusinids studied in the present paper belong to
another particular group of species with a particular
shape and protoconch morphology. Fasciolariidae
with a peculiar protoconch with striking semilunar
axial riblets has been reported from East Atlantic
seamounts by Gofas (2000). This character is shared
with the Indo-West Pacific Fasciolariidae presented
in this paper, which are remarkably similar with the
amfi-Atlantic ÆFusus amiantus Dall, 1889 in
conchological characters, radula morphology and
anatomy, and, consequently, are congeneric.
Amiantofusus gen. nov. has a fasciolariid radula,
however the species are conchologically quite similar
to Buccinidae. Therefore the anatomy of the type
species, Fusus amiantus Dall, 1889, and one of the
new Pacific species was studied. Surprisingly little is
known about the anatomy of Fasciolariidae. Only a
few publications (e.g. Marcus & Marcus, 1962 and
Ponder, 1970) are dedicated to soft-body morphology
and anatomy of this family, as well as a paper on the
79

Amiantofusus gen. nov.
stomach of Buccinoidea (Kantor, 2003), including
descriptions of some fasciolarid species. In the
present paper we discuss the anatomical
characteristics of Fasciolariidae and Buccinidae, to
confirm them as distinct and to derive a correct
definition for Fasciolariidae.
The material described in the present study originates
from various French research vessels and expeditions
in the tropical Indo-West Pacific (e.g. Richer de
Forges, 1993), conducted during the last 30 years,
which are part of the still ongoing sampling program
to study the tropical deep-sea benthos in the Indo-
Pacific, for a better knowledge of the biodiversity:
(a) MUSORSTOM 5, CORAIL 2 and EBISCO
expeditions to the Coral Sea, and especially
Chesterfield-Bellona Plateau (Richer de Forges er al,
1986, Richer de Forges, 1990).
(b) BATHUS 1, 2 & 3, BIOCAL, HALIPRO 1,
BIOGEOCAL, CHALCAL 2, SMIB 3, 4 & 8,
MUSORSTOM 6, NORFOLK 1 & 2 and BERYX 11
expeditions off eastern and southern New Caledonia
(Loyalty Basin) and Loyalty Ridge (Richer de Forges
& Chevillon, 1996).
(c) BATHUS 4 and MUSORSTOM 4 expeditions off
northern New Caledonia.
(d) MUSORSTOM 7 expedition to the Fiji Basin.
(e) VOLSMAR and MUSORSTOM 8 expeditions to
Vanuatu and the New Hebrides Arc (Volcanos

Material from the French expeditions 1s, unless
otherwise stated, deposited in MNHN. The material is,
unless being a type (which are allocated to catalogue
numbers), unambiguously designated and retrievable
by the combination of expedition acronym and station
number.

SYSTEMATICS
Family FASCIOLARIIDAE Rafinesque, 1815
Diagnosis and discussion. It is not easy to draw clear
distinction between Fasciolariidae and Buccinidae,
which have rather similar anatomy. Traditionally the
differentiation has been made on the basis of the
radula. Fasciolariidae possess the broad lateral teeth
with many cusps (more than 5) and very small central
and narrow tooth with 1 to several weak cusps.
Buccinidae, on the contrary are usually having 2-4
cusps on the laterals and relatively much broader,
subsquare central tooth with 3-4 cusps. In fact this is
not that straightforward. There are some genera which
have basically the fasciolariid radula type, but
classified within Buccinidae. One of these genera is
Thalassoplanes Dall, 1908. The radula was illustrated
by Bouchet & Warén (1986: pl. 1, fig. 5) and it is
superficially very similar to that of Fasciolaria. The
anatomy of Brevisiphonia circumreta Lus, 1973 (the
type species of Thalassoplanes) was described by Lus
(1973), who attributed the genus to Fasciolariidae.
Similarly, Troschelia berniciensis (King, 1846) has
“fasciolariid-like” lateral radular teeth with 5-10 cusps
(Bouchet & Warén, 1985: figs 484-485), but it was
attributed by the latter authors to Buccinidae.
Although Ponder (1970) concluded, that there are no
reliable anatomical differences, that readily
distinguish the families of Buccinoidea; Kantor (2003)
stated that stomach anatomy is similar in all
Fasciolaridae examined and allows to distinguish
them from other Buccinoidea in a combination of
characteristics, particularly in the absence of the
posterior mixing area (sometimes called as caecum),
in the low relief of the folds on the inner stomach
wall, in the presence of transverse striations on the
low longitudinal fold, in the absence of clear
differentiation of the gastric chamber into dorsal and
ventral parts.
The foregut anatomy ïis rather uniform in all
buccinoideans, and is characterized by a long
proboscis, large paired or fused acinous salivary
glands, a usually well developed valve and gland of
Leiblein, and by the absence of accessory salivary
glands. Nevertheless there are some minute
differences, that seems to be important. One of them is
the passage of the ducts of the salivary glands. In
Buccinidae the ducts, after leaving the glands, are
following freely along the anterior oesophagus
towards the anterior part of the proboscis, where they
enter the walls of the oesophagus close to their
entrance Into the buccal cavity. In Fasciolariidae to the
contrary (Leucozonia nassa, by Marcus & Marcus,
1962), the ducts, shortly after leaving the glands, enter
the anterior oesophagus walls in front of the valve of
Leiblein. They follow to their openings into the buccal
cavity under the lateral folds of the oesophagus.
Ponder (1970) unfortunately did not write anything
NOVAPEX 8 (3-4): 79-101, 10 décembre 2007
specific on the ducts in his description of the anatomy
of Microfulgur carinatus Ponder, 1970.
The second characteristic are the proboscis retractor
muscles. In Buccinidae the retractors are usually
numerous and are attached in bundles laterally to the
median to the proboscis sheath (— rhynchocoel). In
Fasciolariidae there are either the single pair of the
retractors, or even there can be a single powerful
retractor, attached to rhynchocoel (Ponder, 1970;
Marcus & Marcus, 1962 and Kantor, unpublished).
The combination of the above mentioned
characteristics, that are multicuspid lateral radular
teeth together with very small central tooth, single or
paired proboscis retractors, salivary ducts passing
within the oesophagus walls and characteristic
stomach morphology seems to allow to diagnose
Fasciolariidae confidentially.
It also should be specified, that only the combination
of all these characteristics confirms the placement of a
genus within Fasciolariidae, while single character
may be present in Buccinidae as well. Thus,
Thalassoplanes possesses a clearly fasciolariid radula,
but the stomach has a very long posterior mixing area
and salivary ducts which pass freely along the anterior
oesophagus (Lus, 1973).
Amiantofusus gen. nov. possesses the anatomical
characters, mentioned above for Fasciolariidae:
position of the salivary ducts, the single or paired
proboscis retractors, as well as stomach morphology,
all very similar to that of other Fasciolariidae
(although due to fixation we were not able to examine
it in details). The combination of these characters
allows us to prove the position of the genus within
Fasciolariidae.
Genus Amiantofusus gen. nov.
Type species: Fusus amiantus Dall, 1889, amfi-atlantic
(West Atlantic: northern Caribbean. East Atlantic:
around Azores).
Description. Shell small to medium, white, yellowish,
pale brown to orange-brown, fusiform, slender, with
high spire and rather short siphonal canal.
Protoconch multispiral, pointed, with 3 - 3 1/2 whorls.

strong, semilunar, axial riblets and with ll,
occasionally 2, fine suprasutural spiral cord(s).
Teleoconch whorls ornamented with spiral cords,
weak or invisible in the axial interspaces, forming
well developed knobs on the axial ribs. Their number
increasing from 2 (occasionally 3) on the first whorl to
4-6 on penultimate whorl. Most species develop
secondary spiral cords.
Aperture ovate to narrow, more or less pinched at both
ends. Outer lip simple, usually thin. Columella
smooth, callus thin. Outer lip and columella usually

knobs or lirae inside outer lip. Siphonal canal short,
broad, open.
Operculum corneus, thin, pale brown, rather small,
elongate, nucleus terminal.
Radula with small, narrow, tricuspid central tooth with
elongate base. Lateral teeth broad, slightly curved,
With 4 major cusps accompanied by a small knob or
cusp at both ends.
Anatomy and operculum of Amiantofusus amiantus
(Dall, 1889), was studied in an adult male (spire
length 14.0 mm, body whorl length 8.3 mm, apertural
length 5.6 mm, siphonal width 5.3 mm. Shell with 3.8
protoconch and 5.75 teleoconch whorls) from Meteor
Bank (central Atlantic), SEAMOUNT 2, stn DWI180.
Body light yellow (preserved), digestive gland light
orange, testis slightly lighter, upper whorls were torn
off by extracting the body from the shell, mantle
cavity spanning slightly over 1/2 whorl. Nephridium
narrow spanning about 1/5 whorl, nephridial gland
narrow, With transparent walls (Fig. 6 — ng). Lobes of
the digestive gland fuse without distinct border. The
gland occupies the ventral part of the upper whorls of
visceral mass, the border line between digestive gland
and the testis is slightly wavy (Fig. 1).
Foot thick, with subrectangular sole, rounded
posteriorly. Propodium narrow (Fig. 2 — prp),
separated from metapodium by very narrow and
shallow propodial cleft. Operculum (Fig. 1 — op)
completely transparent, light yellow, very thin,
elongate-oval, with terminal nucleus, nucleus eroded.
Growth lines very thin, inconspicuous, and numerous.
Operculum attached along short oval area (under 1/2
of operculum length) to opercular pad. Head medium-
sized, poorly differentiated from the foot, tentacles
long (Figs 2-3 — cept), closely spaced at the bases,
conical with distinct black eyes, at tentacles bases.
Mantle cavity. Mantle cavity is in all respects similar
to that of Amiantofusus pacificus (Fig. 9), long, its
length about 1 1/2 the width, edge even and thickened
when animal is contracted. Mantle wall very thin,
osphradium, ctenidium, pallial gonoduct, and
hypobranchial gland visible by transparency. Siphon
with thick and contracted walls, short, very slightly
extending beyond mantle edge. Ctenidium large, but
narrow, Ooccupying about 0.9 of mantle length,
consisting of simple tall triangular lamellae.
Osphradium twice as wide as ctenidium and 0.6 of its
length, assymmetrical, with broad axis. Its lamellae on
the right side are wider than on the left side, especially
in the anterior part in proximity to the mantle edge.
Hypobranchial gland indistinct, narrow, lacking folds,
covered with thick mucus layer. Rectum narrow, thin-
walled, of similar diameter along its length, without
terminal papilla. Rectal gland absent.
Alimentary system (Figs 4-6). Proboscis medium long
in contracted state (about 1.8 mm, or 0.32 aperture
length), with smooth walls, occupying most of
rhynchocoel length, rhynchodeum semitransparent.
82
Proboscis narrow, length about 5.5 diameter. Mouth
opening broad (Fig. 5) compared to proboscis
diameter, in the shape of dorso-ventrally compressed
narrow slit. Proboscis retractor large (Figs 4-5 — prr),
unpaired, attached to the rhynchodaeum ventrally at
its mid-length.
Oesophagus leaving proboscis posteriorly is broad,
rounded in section and forming very long loop (Fig.
5). Valve of Leiblein large (Fig. 5 — vL), comparing to
oesophagus diameter, pyriform, the ciliar conical
valve is visible through transparency of the walls of
the valve. The valve is situated anterior to proboscis
tip, when the latter is retracted. Oesophagus narrow
immediately posterior to the valve and passing
through the nerve ring. Circumoesophageal nerve ring
comparatively large (Fig. 5 — nr), concentrated,
covered with thick connective-tissue layer, that is
obscuring the borders between ganglia. Mid-
oesophagus after passing through the nerve ring
slightly widens, covered with loose connective tissue,
which is obscuring the duct of the gland of Leiblein.
Posterior oesophagus (posterior to the opening of the
duct of the gland of Leiblein) of the same diameter
along its length, thin-walled. Gland of Leiblein long
(Figs 4-5 — gL), light yellow-brownish, tubular,
uncoiled, tapering posteriorly.
Salivary glands large, situated on both sides of
anterior part of rhynchodaeum and the
circumoesophageal nerve ring, completely covering
the latter (Figs 4-5 — rsg, Isg). The glands are semi-
transparent, off white, judging from the external view
acinous. Salivary ducts leaving the glands and fused
with the walls of the oesophagus immediately anterior
to the valve of Leiblein. The duct of the left salivary
gland is much thicker, than that of the right gland. The
ducts are visible through the oesophagus wall by
transparency, as they follow anteriorly (Fig. 5 — sd).
Accessory salivary glands absent. Stomach small (Fig.
6 — st), broadly U-shaped, without posterior mixing
area. The outer stomach wall is covered by thin but
distinct transverse folds visible by transparency.
Posterior oesophagus opens into the stomach vetro-
posteriorly (Fig. 6 — poe). Due to fixation it was
impossible to study stomach anatomy.
Reproductive system. Penis is medium long (Fig. 3 —
p), rounded in section at the base and more flattened
closer to the apex, slightly narrowing towards the tip.
Seminal duct is clearly visible by transparency.
Seminal opening lacking papilla.
Comparison. Amiantofusus gen. nov. is characterized
by the multispiral protoconch, with semilunar axial ribs
and 1, occasionally 2, suprasutural spiral cords, in
combination with strong axial sculpture and short
siphonal canal.
Subadult specimens are more common than full adults.
The shape of adult shells can differ considerably by a
proportionally larger aperture and shorter siphonal
canal.
K. FRAUSSEN, Y. KANTOR & R. HADORN
The presence of a protoconch with peculiar semilunar
axial ribs in combination with one or more suprasutural
spiral cords is shared with the East Atlantic fasciolariid
species “Latirus” rugosissimus (Locard, 1897) and
buccinid Antillophos species (Indo-West Pacific and
Caribbean). Some of these species are more common
on seamounts (Antillophos alabastrum (Fraussen,
2003) and Antillophos boucheti (Fraussen, 2003)). For
a discussion of East Atlantic seamount species with
axial ribs on the protoconch (although not all
semilunar) we refer to Gofas (2000).
Species of the deep-water subgenus Fusinus
(Chryseofusus) Hadorn & Fraussen, 2003 have a short
siphonal canal too, but differ by the smooth paucispiral
protoconch, the higher number of spiral cords and by
radular morphology (central tooth with broader base,
lateral teeth with 4-8 cusps).
Species accommodated in the buccinid deep-water
genus Manaria Smith, 1906 (type species M. thurstoni
Smith, 1906 by original description, northern Indian
Ocean, Buccinidae) may have a similar shape but differ
by the smooth paucispiral protoconch, by a usually
higher number of primary spiral cords but lower
number of secondary spiral cords, by the weaker axial
ribs and by radular morphology (which is buccinid,
central tooth broader, lateral tooth with 2 cusps). For
more details on this genus we refer to Bouchet &
Warén, 1986.
Species of the turbinellid genus Merzgeria Norman,
1879 (new name for Meyeria Dunker & Metzger, 1874,
type species Lathyrus albellus Dunker & Metzger,
1874 by monotypy, junior synonym of Latirus albus
Jeffreys in Wyville-Thompson, 1873, northern
Atlantic, Turbinellidae) differ by the presence of
columellar folds and by radular morphology (lateral
teeth with one cusp). Meyeria decorata Locard, 1897
has been assigned to Turbinellidae (Cernohorsky,
1973: 125), until Bouchet & Warén (1986: 161, 254)
have recognized the species as a junior synonym of
Fusinus amiantus (Dall, 1889).

Distribution. Amiantofusus amiantus is an amfi-
Atlantic species. In the West Atlantic known from the
northern Caribbean, off Cuba (Dall, 1889: 169). In the
East Atlantic known, not from the continental shelf, but
on the seamounts and slopes of the Azores and Madeira
(Bouchet & Warén, 1985: 161) and on Meteor, Irving
and Plato Bank (Gofas, 2000: 10).
Remarks. Amiantofusus amiantus is characterized by
the fusinid shape but with short siphonal canal, in
combination with a multispiral protoconch and the
presence of peculiar semilunar axial ribs on the lower
protoconch whorl.
Amiantofusus amiantus displays considerable
variability in shape. Subadult specimens have a smaller
aperture in combination with a longer siphonal canal.
Adult specimens have a wider outer lip and shorter
siphonal canal, the shape of the base looks more
rounded. The spiral and axial sculpture is rather
constant.
Fusinus bocagei (P. Fischer, 1882) differs by the
protoconch (finer and lesser curved axial ribs, broader
interspaces, the absence of subsutural spiral cords), the
longer siphonal canal, the absence of a thick lip and the
higher number of primary spiral cords (3 on the spire,
up to 9 on the body whorl).

abapical end. Ornamented with suprasutural spiral
cord.
Teleoconch consisting of 7 1/4 convex whorls.
First teleoconch whorl with 2 sharp primary spiral
cords and 1 additional, fine, subsutural cord. Second
whorl with a fourth spiral cord partly concealed under
lower suture. Third whorl with 3 primary cords,
adapical one finer, and 1 additional, fine, subsutural

strong, convex primary spiral cords, interspaces with
3-5 fine secondary spiral cords, in addition 4 or 5 fine
subsutural spiral cords.
Body whorl with 9 or 10 primary spiral cords, 3-5,
occasionally 6, secondary spiral cords between each
adapical pair of primary cords. 1-4 fine secondary
spiral cords between each abapical pair of primary
cords. Siphonal canal with some broad spiral cords,
occasionally alternating strong and fine.
AIT whorls with 8 or 9 sharp axial ribs, running from
suture to suture. Interspaces twice as broad.

Anatomy of À. pacificus sp. nov., a female specimen
(spire length 21.0 mm, body whorl length 12.0 mm,
apertural length 10.2 mm, siphonal width 8.2 mm)
from Jumeau West Bank, Loyalty Ridge (southern
New Caledonia), BATHUS 3, stn DW809.
Body light yellow when preserved, consisting of about
3 1/2 whorls, mantle cavity spanning about 3/4 whorl,
digestive gland about 2 whorls, ovary about 3 upper
whorls (Figs 7-8). Although the body was deeply
retracted into the shell, the upper 6 whorls, 3 1/4 of
which are teleoconch whorls, were not occupied by
the body, but filled with mucus. Nephridium (Fig. 8 —
nep) narrow spanning about 1/5 whorl, preservation
precludes studies of internal anatomy. Nephridial

gland narrow, with transparent walls. Lobes of the
digestive gland fuse without distinct border. The gland
occupies the ventral part of the upper whorls of
visceral mass, the border line between digestive gland
and the ovary is wavy (Figs 7-8).
Foot thick, with subrectangular sole, gradually
narrowing posteriorly. Propodium narrow, separated
from metapodium by narrow and shallow propodial
cleft. Head small, poorly differentiated from the foot,
tentacles long, but folded during fixation, conical,
with distinct light-brown eyes at tentacles bases (Fig.
8 — cept).
Mantle cavity (Fig. 9). Mantle cavity long, its length
about 1.5 the width, edge even and thickened when
animal is contracted. Mantle wall thin, osphradium,
ctenidium, pallial gonoduct, and hypobranchial gland
visible by transparency. Siphon with thick and
contracted walls, short, very slightly extending beyond
mantle edge. Ctenidium (Fig. 9 — ct) large, but
narrow, occupying about 0.9 of mantle length,
consisting of simple tall triangular lamellae.
Osphradium twice as wide as ctenidium and 0.6 of its
length (Fig. 9 — os), asymmetrical, with broad axis. Its
lamellae on the right side are wider than on the left
side, especially in the anterior part in proximity to the
mantle edge. Hypobranchial gland indistinct, narrow,
lacking folds, covered with thick mucus layer (Fig. 9 —
hg). Rectum narrow, thin-walled, of similar diameter
along its length, without terminal papilla. Rectal gland
absent.
Alimentary system (Figs 10-13). Proboscis long in
contracted state (about 4.5 mm, or 0.44 AL), with
smooth walls, occupying entire rhynchocoel length,
rhynchodeum semitransparent. Proboscis narrow,
length about 8 1/2 diameter. Mouth opening broad
compared to proboscis diameter, in the shape of
dorso-ventrally compressed narrow slit. Proboscis
retractors very thin, attached to the rhynchodaeum
laterally in its anterior third (Figs 10-12 — prr). The
retractor attached to the right side of rhynchodaeum is
larger, consists of single muscle, while those, attached
to the left side are thinner and consists of few separate
muscle fibers.
Oesophagus leaving proboscis posteriorly is broad but
flattened, forming a rather long loop. Valve of
Leiblein large (Fig. 12 — vL), compared to oesophagus
diameter, pyriform, the ciliar conical valve is visible
through transparency of the walls of the valve.
Oesophagus narrow immediately posterior to the valve
and passing through the nerve ring.
Circumoesophageal nerve ring comparatively large
(Fig. 12 — nr), concentrated, covered with thick
connective-tissue layer. Mid-oesophagus after passing
through the nerve ring slightly widens and received
short but broad duct of the gland of Leiblein (Fig. 12 —
dgL). Posterior esophagus (posterior to the opening of
the duct of the gland of Leiblein) slightly widens, but
is very thin-walled, nearly transparent. Gland of
88
Amiantofusus gen. nov.
Leiblein long, colorless in preserved condition,
tubular, uncoiled, tapering posteriorly, very thin-
walled, semi-transparent (Figs 10-12 — gL).
Salivary glands very large situated on both sides of
anterior part of rhynchodaeum and the
circumoesophageal nerve ring, completely covering
the latter’ (Figs 10-11 — Isg, rsg). Salivary ducts
leaving the glands and fused with the walls of the
oesophagus immediately anterior to the valve of
Leiblein (Figs 11, 12 — sd). Accessory salivary glands
absent. Stomach small, broadly U-shaped, without
posterior mixing area (Fig. 13 — st). Posterior
oesophagus opens into the stomach vetro-posteriorly.
Due to fixation it was impossible to study stomach
anatomy.
The two examined species, À. amiantus and À.
pacificus Sp. nov. are very similar to each other both
in radulae and anatomy. The only difference that can
be mentioned is that 4. amiantus has clearly a single
proboscis retractor, attached nearly ventrally to the
rhynchodaeum, while À. pacificus sp. nov. has a
similar retractor, but attached more laterally on the
right side, while there are additional thin muscle fibers
attached to the rhynchodaeum on the left side and
probably also functioning as retractors.
Comparison. Amiantofusus pacificus Sp. nov. exhibits
a strong degree of, mostly geographic indicated,
variability. The multispiral protoconch indicates a
planktotrophic development and a wide distribution.
This is reflected in the geographic range indeed (from
Taiwan, via North Fiji Basin to northern and southern
New Caledonia, southern Coral Sea, Vanuatu and
Tonga). The bathymetric range is rather narrow (420-
795 m). The populations are separated by deeper water,
causing a certain geographic isolation which is well
reflected by the differences in shell morphology. A
number of intermediates are collected (between most of
the forms), evidence that these populations are not fully
separated entities. Therefore we consider them merely
as a variant, calling them a form. Here we use “form"
in the common used sense, instead of the correct
expression for "form", which is "phenon" (Mayr &
Ashlock, 1991: 20).
Form A, the “Norfolk Ridge form” (fig. 34-35), 1s
rather small and usually has a slightly larger siphonal
canal, the colour ranges from pale orange to bright
orange.
This form lives on the southwestern part of Norfolk
Ridge at 500-780 m. Empty shells between 435 and
850 m.
Form B, the “Loyalty Ridge form” (figs 36-37), is
smaller and paler, has sharper knobs on the axial ribs,
has usually a higher number of secondary spiral cords
(4 or 5).
This form lives on Loyalty Ridge and has a slightly
deeper bathymetric range at 680-770 m. Empty shells
between 505 and 850 m.
K. FRAUSSEN, Y. KANTOR & R. HADORN
Form C, the “solid form” (figs 38-39), has a slightly
thicker shell, giving the specimens a solid appearance.
The primary spiral cords and the axial sculpture
gradually become weaker on the penultimate whorl and
the body whorl has a smooth appearance. The colour 1s
pale orange to white.
This form lives on southern New Caledonia slope and
the northern part of Norfolk Ridge (where it is
connected and gradually mixing with form A in the
south), on the northern part of Loyalty Ridge (where it
is connected and gradually mixing with form B) and
in the north-western area of the range (southern Coral
Sea and off Noumea). Bathymetric range 515-585 m.
Empty shells between 500 and 800 m.
Form D, the “smooth form” (figs 40-45), has a body
whorl without any axial sculpture. The specimens
from northern New Caledonia (off Entrecasteaux
Reef) are small, the specimens from southern New
Caledonia and off Tonga usually are exceptionally
large for the species. Bathymetric range 613-680 m.
Empty shells between 600 and 680 m. A specimen of
this form is found together with “form A” at
BATHUS 3, stn DW809.
The above mentioned difference in body whorl
sculpture is not sufficient to describe this shell as a
distinct species.
Form E, the “Vitiaz form” (figs 68-69), has a thick
and solid shell with big axial ribs and strong
secondary spiral cords, in combination with a weaker
subsutural cord. The protoconch is slightly shorter
(1.0 mm high, diameter 0.9 mm), usually with many,
slightly straighter axial riblets. This minute difference
in protoconch morphology is not sufficient to describe
this shell as a distinct species.
This form lives on the banks of the Vitiaz Zone in
north Fiji Basin. The single specimen from off Taiwan
(TAIWAN 2000, stn DW56) is much similar.
Form F, represented by a single specimen, has a
slightly larger protoconch, and the primary cords
appear earlier and are well visible (the third spiral cord
already on the first whorl, the fourth spiral cords on the
third whorl).
This specimen originates from Introuvable Bank
(NORFOLK 1, stn DW1696) on the eastern part of
Norfolk Ridge.
Amiantofusus amiantus comb. nov. is similar in
sculpture but differs in having a higher spire and a
more knobbed sculpture.
“Fusus” thielei Schepman, 1911 is similar in sculpture
and may look similar to specimens from northern Fiji
Basin, but differs in having a broader shape and a
subsutural concavity which is slightly deeper. The
spiral sculpture is slightly sharper.
Etymology. Named after the Pacific Ocean, conjuring
up the contrast with the Atlantic Ocean were the type
species Amiantofusus amiantus (Dall, 1889) is living.

Amiantofusus gen. nov.
Comparison. Amiantofusus gloriabundus sp. nov. is
characterized by the large semi-transparent shell with a
reticulate appearance on the spire and a large number
of weak axial ribs on the two last whorls.
imiantofusus pacificus sp. nov. form E, the “Vitiaz
form”, which is also found at Field Bank (North Fiji
Basin), differs by the more pronounced spiral sculpture
with 3 primary spiral cords (instead of 4), stronger
secondary spiral cords, and a lower number of axial
ribs.
AIT other Amiantofusus species described in this paper
differ by the lower number of axial ribs on the
penultimate and body whorl.
Fusus thielei Schepman, 1911 differs in having a
strongly twisted columella, a lower number of axial
ribs and a longer siphonal canal.
Etymology. Amiantofusus gloriabundus Sp. nov. is
named after the Latin expression gloriabundus
(adjective), meaning "flaunty", to express the
exceptional beauty of this shell.

Comparison. The single specimen is similar to À.
gloriabundus sp. nov. in colour, spiral sculpture and by
the fine incremental lines but differs by the slender
shape and lower number of axial ribs.
Amiantofusus pacificus Sp. nov. differs by the larger
protoconch and by the primary spiral cords which are
fewer in number and lesser pronounced.

1/6 part becoming slightly narrower with stronger axial
riblets.
About 7 1/4 teleoconch whorls, all with 2 primary
spiral cords, weak or invisible in axial interspaces,
more developed on axial ribs, forming weak or strong
knobs. Occasionally an additional third primary spiral
cord suprasuturally visible. Secondary spiral cords
weak or absent, when visible 3 or 4 between primary
cords, about 8 on subsutural slope, numerous on body
whorl.
First whorls with 10 or 11 axial ribs, running from
suture to suture. Interspaces broad. Body whorl with 0-
12 ribs.
Aperture semi-ovate, narrow, pinched at both ends. Lip
thin. Columella smooth, callus thin. Siphonal canal
moderately short.
Periostracum, operculum and radula unknown.
Comparison. Amiantofusus sebalis sp. nov. is
characterized by its small size, its slender shape with 2
primary spiral cords and fine secondary spiral cords.
Amiantofusus pacificus sp. nov. differs in having a
more obvious sculpture, a broader shape with shorter
siphonal canal in combination with a larger adult size.
For differences with À. maestratii Sp. nov., À. candoris
sp. nov. and À. borbonica sp. nov. we refer to the
comparison under these species.
Etymology. Amiantofusus sebalis sp. nov. is named
after the Latin expression sebalis (adjective), meaning
"made from talcum". Indeed the small shell with a
rather dull surface looks rather talcose.

Comparison. The single specimen is similar to À.
sebalis sp. nov. in shape and colour but differs by the
slightly broader spire, the larger size (8 1/2 teleoconch
whorls, 30.5 mm in length) and the more convex
whorls. These weak differences are not sufficient to
describe this shell before more material is available.

leleoconch consisting of 8 3/4 whorls. Upper spire
whorls with 2 weak primary spiral cords, weak on
axial ribs, almost invisible in interspaces, with broad
straight subsutural slope. Abapical spiral cord
becoming weaker from fourth whorl on, almost
indistinguishable from secondary spiral cords on fifth
or sixth whorl. Suture wavy on upper spire whorls,
straight on penultimate and body whorl. From third
whorl on some weak, smooth secondary spiral cords
appearing between both primary spiral cords and on
subsutural slope. On later whorls their number
increasing up to 25, fine, evenly spaced spiral cords.
Body whorl with numerous fine, weak spiral cords.
First whorls with 9 strong axial ribs, running from
suture to suture. Interspaces broad. From second whorl
on with 8 axial ribs. Axial ribs gradually becoming
weaker near both sutures, fifth and sixth whorl with a
sharp axial knob on periphery.
Aperture semi-ovate. Outer lip slightly curved
outwards. Columella smooth, gently curved. Siphonal
canal short, narrow.
Periostracum, radula and operculum unknown.
Comparison. Amiantofusus candoris sp. nov. is
characterized by the slender, thin, semi-transparent
shell with 2 primary spiral cords on the upper whorl of
which the abapical one is gradually becoming weaker,
and with fine, smooth, evenly spaced secondary spiral
cords.
Amiantofusus sebalis Sp. nov. is similar in spiral
sculpture (2 primary cords on the upper spire whorls,
many secondary cords) but differs by the secondary
spiral cords which are fine and well distinguishable
from the primary cords even where the primary cords
are fading, the presence of axial ribs on the penultimate
whorl, the (almost) smooth body whorl, the smaller
protoconch with narrower last whorl and by the smaller
size.
Amiantofusus maestratit Sp. nov. differs in having a
solid shell, a broader shape with shorter spire, smooth
spiral interspaces and a white protoconch with more
axial riblets.
Amiantofusus pacificus sp. nov. differs in having a
more pronounced spiral sculpture in combination with
a broader shape.
Etymology. Amiantofusus candoris sp. nov. is named
after candor or candoris (Latin, masculine), meaning
"heavy white colour” or “dazzling beauty” which refers
to the white colour and the elegant shell.

Amiantofusus gen. nov.
Comparison. Amiantofusus maestratii Sp. nov. is
characterized by the heavy shell with 2 primary spiral
cords resulting in a shape dominated by 2 rows of
knobs.
Amiantofusus sebalis sp. nov. is similar in spiral
sculpture (2 primary cords, many secondary cords) but
differs by the smaller size, the thinner shell, the more
elongate spire and the (almost) smooth body whorl.
Amiantofusus candoris sp. nov. differs by the thin
shell, the slender shape with higher spire, and the
presence of secondary spiral cords.
Amiantofusus pacificus Sp. nov. differs in having a
more pronounced spiral sculpture in combination with
a broader shape.
Etymology. Amiantofusus maestratii Sp. nov. is named
to honour Philippe Maestrati (Muséum national
d'Histoire naturelle, Paris) for his contributions to
malacology, for his important help while studying the
material available in MNHN, and for the pleasant hours
we spent on Mactan Island, Philippine Islands.

1/6 part becoming slightly narrower with stronger axial
riblets.
Teleoconch consisting of 5 1/2 whorls.
First teleoconch whorl with 2 primary spiral cords,
weak in interspaces, strong on axial ribs, forming well
developed knobs. From second whorl on an additional
third primary spiral cord appears suprasuturally,
becoming as strong as other cords from third whorl on.
Occasionally a weak, hardly visible, secondary spiral
cord present from third whorl on. Penultimate whorl
with 3 or 4 primary spiral cords, 1-4 weak secondary
spiral cords between each pair of primary cords. Body
whorl with 14-16 spiral cords, of which 6 on whorl
with 1 or 3 (rarely 2) secondary spiral cords, and 8-10
broad, low spiral cords on siphonal canal.
First whorls with 9-11 strong axial ribs, running from
suture to suture. Interspaces broad. Body whorl with
12 or 13 axial ribs.
Aperture semi-ovate. Columella gently curved. Outer
lip thin, edge sharp. Siphonal canal short.
Periostracum, radula and operculum unknown.
Comparison. Although 4. borbonica sp. nov. is only
known from subadult specimens, it is already possible
to distinguish this species from 4. cartilago sp. nov.
The morphological differences in species of
Amiantofusus are more manifest on the upper whorls.
For differences with À. cartilago sp. nov. we refer to
the comparison under that species.
Amiantofusus sebalis sp. nov. differs by the more
slender shape, the presence of a subsutural concavity
and the different spiral sculpture (2 primary cords only,
the occasional visible third cord being suprasutural
instead of being on the subsutural slope).
Etymology. Amiantofusus borbonica sp. nov. is named
after Ile Borbon, also called Ile Bourbon, the ancient
name for Reunion.

Description. Shell of medium size (up to 35.6 mm),
thick, solid, fusiform, slender with high spire and short
siphonal canal. White.
Protoconch decollate in all studied specimens except
holotype (about 1 1/3 remaining whorls), white,

Penultimate whorl with 4 primary spiral cords, 3 weak
secondary spiral cords between each pair of primary
cords. Body whorl with 7 or 8 primary spiral cords,
each interspace with 3 or 4 secondary spiral cords, and
about 12 broad, low spiral cords on siphonal canal.
First whorls with 9-11 strong axial ribs, running from
suture to suture. Interspaces broad. Penultimate whorl
with 10-12 axial ribs, body whorl with 9 or 10 ribs.

Paratype 3 with slightly deformed shape, last whorls
without axial sculpture.
Aperture semi-ovate. Columella gently curved. Outer
lip thin, edge sharp. Siphonal canal short.
Periostracum, radula and operculum unknown.
Comparison. Amiantofusus cartilago sp. nov. is
characterized by a bigger last protoconch whorl
(instead of becoming narrower), a larger and solid
shell, and the presence of a weak subsutural cord on the
first 3 teleoconch whorls.
Buccinid species assigned to the genus Manaria
Smith, 1906 (type species: Manaria thurstoni Smith,
1906, India) look rather similar to À. cartilago sp.
nov. but differ by the spiral sculpture consisting of a
higher number of primary spiral cords but a lower
number of secondary cords, and by the axial sculpture
consisting of stronger ribs but lesser developed knobs
on the spiral cords.
Fusinus retiarius (von Martens, 1901), collected by the
same vessels as À. cartilago sp. nov., looks similar but
differs by the broader spire, the stronger spiral
sculpture, and the protoconch without axial riblets.
Amiantofusus borbonica sp. nov. differs by the more
narrow last protoconch whorl, the absence of the weak
subsutural cord on the first 3 whorls, and the shape of
the spire which is slightly broader.
Etymology. This species name is derived from
cartilago (Latin) meaning "cartilage". The white shell
with a smooth surface rather looking as made from
this material.

Amiantofusus gen. nov.
lhis species 1s much similar to Amiantofusus pacificus
sp. nov. but differs by having a broader shape, a
shghtly deeper subsutural concavity, a more twisted
columella, sharp spiral cords on the base with wider
and smooth interspaces. The radula differs from
Amiantofusus by having an oval central tooth. The
holotype and the specimen from North Fiji Basin are
the single known specimen, but both have a decollate
protoconch, consequently we cannot ascertain nor
refuse the placement of this species in Amiantofusus.
Excluded species
Latirus rugosissimus (Locard, 1897)
Clathurella rugosissima Locard, 1897. Material from
East Atlantic seamounts (Meteor, Hyères, Plato and
Atlantis seamounts) assigned to Latirus Montfort, 1810
by Gofas (2000: 13-14). This species has a protoconch
identical to Amiantofusus gen. nov. We follow the
opinion of Gofas, based on morphological
characteristics of the teleoconch sculpture.

KEY WORDS. Bivalvia, Pectinidae, Semipallium coruscans coruscans, Manupecten pesfelis, Adriatic
Sea.
ABSTRACT. The report of Semipallium coruscans coruscans (Hinds, 1845) from the Adriatic Sea is the
subject of discussion. Some juvenile pectinid species collected in association with Corallium rubrum
(Linné, 1758) were studied and one of the authors (J. P.) noticed that juvenile specimens of Manupecten
pesfelis (Linné, 1758) show great similarity with S. coruscans coruscans (Hinds, 1845) reported from the
Adriatic Sea. Subsequently we decided to make a broader study of these two species and at the end of our
study we can confirm that the report of Semipallium coruscans coruscans from the Adriatic Sea is a
misidentification of Manupecten pesfelis. We noticed that Semipallium coruscans coruscans Was
transferred to the genus Pascahinnites Dijkstra & Raines, 1999.
INTRODUCTION
The work of Siletié (2004) about the discovery of a
single specimen of Semipallium coruscans coruscans
(Hinds, 1845) from Mljet Island, Croatia came to the
knowledge of the first author and he noticed that this
specimen 1s very similar to some specimens from his
collection already identified as juvenile specimens of
Manupecten pesfelis (Linné, 1758). To confirm his
supposition we tried to find some other specimens and
met with success. In some shell grit collected by
fishermen on red coral, off Mljet Island at depths from
60 to 90 m, we found many pectinid specimens, some
of which were M. pesfelis at different stages of
growth.
Moreover, Siletié confirmed her first report in a
second work (Siletié, 2006) where she specified that
the specimen was collected at depth of 80 m, on a
colony of Cellaria fistulosa (Linné, 1758) a Bryozoa
less calcified than red coral.
After examination of the specimens from Mljet Island
we compared them with some specimens of S.
coruscans coruscans from Raïatea Island, French
Polynesia, and so far as possible we compared shells
of a similar size.

Distribution of the two species. The distribution of
Manupecten pesfelis Was reported by Linné (1758)
from “©. Africano” (incorrect locality) as stated by
Dikstra (1999) who gives a new restricted locality:
“Mediterranean Sea”. It was also reported by Wagner
(1991) as: “The species is confined to the
Mediterranean and the adjacent area of the Atlantic
Ocean from Portugal to the Azores and south to Cape
Verde” and about habitat he wrote: “On gravelly or
corallinous bottoms from 10 to 250 m”. Some years
after Dijkstra & Goud (2002) reported:
“Mediterranean Sea and adjacent region of eastern
Atlantic from Portugal southwards to the Cape Verde
Islands. Living littorally to bathyal depths among
coral rubble or gravel on sandy bottoms. Present
material dead in 0-540 m”. Recently Raines & Poppe
! After this article had been reviewed by referees and accepted by the editor, the authors became aware of a similar work
published by Trono & Resta (2007). Notwithstanding, they decided to publish their paper because it contains useful
illustrations and important information about the distribution and the description of both species.

PRKIC, TISSELLI & GIUNCHI
Semipallium coruscans coruscans in the Adriatic Sea
(2006) report it as: “From Mediterranean Sea and the
adjacent Atlantic Ocean; from Portugal to Cape Verde
including the Azores and Canary Islands” and about
habitat they report: “Littoral to sublittoral zone, under
rocks on gravelly sandy bottoms with coral rubble”.
We report that M. pesfelis on the Dalmatian coast is
rather common in the infralittoral zone, and in coral
bottoms. In shell grit coming from red coral bottoms,
40-100 m deep, live specimens are of small or
medium size while big specimens are rare and usually
dead.
It lives, attached with a byssus, in fissures in the rocks
and in poorly lit caves because it is adverse to light, so
it 1s difficult to find live specimens because they live
deep in the fissures.
It also likes the old walls built to protect the small
harbours and many big and beautiful specimens were
collected in these places at a depth of 1-2 m.
The first author never found this species under stones
where, on the contrary, Mimachlamys varia varia
(Linné, 1758) and Talochlamys multistriata (Poli,
1795) are very common.
CLEMAM (2007) gives a different genus to these
species but we prefer to use the names proposed by
Dijkstra & Goud (2002) and Dijkstra & Gofas (2004)
because we noticed that CLEMAM is not updated
with the names used in these two works.
The type locality of Semipallium coruscans coruscans
is: Anna Maria Port, Nukuhiva, Marquesas Islands
and it lives byssally attached in areas with clear water
and it prefers areas through which strong streams run
on the external side of the reefs or the passage to the
internal lagoon, at a depth of about few dm up to
about 20 m (Dijkstra, 1983). The report of Raines &
Poppe (2006) is short: “Indo-Pacific region, to include
the eastern and southern coast of Africa”. The habitat
is stated as: “littoral zone, byssally attached to rocks
or coral on sandy bottom”, no depth is given.
The species is not reported for the Red Sea by Oliver
(1992) and Orlin & Dekker (2000) as already stated
by Siletié (2004) so it cannot be considered a
lessepsian migrant.
Material examined. Manupecten pesfelis from Mljet
Island (Croatia) 60-90 m deep: 1 specimen of 2.5 mm,
1 specimen of 3.6 mm, 1 specimen of 6.7 mm and 1
specimen of 13.0 mm all from Giunchi-Tisselli
collection ex Jakov Prkié collection (Figs 1-7).
Semipallium coruscans coruscans from Raïatea Island
(French Polynesia): 1 specimen of 5.5 mm, !
specimen of 9.0 mm and 1 specimen of 10.7 mm all
from Giunchi-Tisselli collection (Figs 8-13).
Description of our material. Manupecten pesfelis.
The sculpture of adult specimens consists of 7 or 8
primary radial ribs and numerous secondary radial
riblets on and between primary ribs. The entire surface
of the shell is covered with a layer consisting of very
fine honeycomb-like microsculpture, giving the shell a
shagreen look. This layer is relatively soft and it can
be easily removed or damaged. When removed or
104
eroded a fine reticulating pattern of lamellae covers
the whole valve (Figs 31, 34). Left valve has primary
ribs more pronounced, more rounded and the
intercostals spaces are larger than the ribs. In the right
valve these ribs are flattened and larger than
intercostals spaces. The number of secondary riblets is
varied on-and between primary ribs. Ribs of anterior
auricles are also different and in the left valve these
ribs are nodulous while in the right valve they are
lamellose. On the dorsal margin of posterior auricles
there are 5-6 strong tubercles (Fig. 33).
The sculpture of juvenile specimens is quite different
from that of adult ones.
In our smallest specimen of 2.5 mm (Figs 1-2) both
valves are sculptured with thin radial striae and a
shagreen microsculpture is not yet formed, only
microscopic lamellae and grooves are visible.
In our specimen of 3.6 mm (Fig. 3), which is almost
identical to that figured in the work of Siletié (2004),
already is present a shagreen microsculpture and some
secondary riblets are formed.
In our specimen of 6.7 mm (Figs 4-5) both valves are
sculptured with primary and secondary riblets,
irregularly arranged, and a shagreen microsculpture
covers the entire surface of the valves except in the
umbonal area. In this growth stage tubercles on the
dorsal margin of auricles are not yet formed.
In our specimen of 13.0 mm (Figs 6-7) there is already
a sculpture similar to that in adult specimens. Primary
radial costae are well formed and secondary radial
riblets are on and between the primary ribs. On the
anterior auricle of the left valve the ribs become
nodulous and on the edge of posterior auricle there is a
strong tubercle. In this specimen too the entire surface
of both valves is covered with a shagreen
microsculpture.
Semipallium coruscans coruscans. The sculpture of
our specimens (Figs 8-13) consist of 14 or 15 primary
radial ribs, regularly arranged, and numerous
secondary riblets mostly on primary ribs and very few
between them. The layer with shagreen microsculpture
is eroded in all our specimens and a fine reticulating
pattern of lamellae covers the valves. Only on left
valve of our specimen of 5.5 mm is one small part of
this shagreen microsculpture preserved (Fig. 21).
In between the secondary riblets a series of
microscopic pits can be seen.
On the dorsal margin of auricles tubercles are absent.
Discussion and conclusion. The main differences that
distinguish M. pesfelis from S. coruscans coruscans
are the large tubercles on the auricles and distinctly
lower number of primary ribs (7 or 8 against 14 or
15). The adult specimens are also much bigger (65-85
mm against 15-22 mm).
The comparison of juvenile specimens of M. pesfelis
and $. coruscans coruscans of about the same size,
also show some differences.
The shagreen microsculpture is similar in both species
but in M. pesfelis it is more prominent and the cells

are deeper and larger than those in S. coruscans
coruscans. It seems that, in the second species, this
microsculpture is very delicate and consequently it 1s
usually eroded while in juvenile specimens of M.
pesfelis it is usually very well preserved.
In the Indo-Pacific species primary radial ribs are well
formed and regularly arranged in all three specimens
(Figs 8-13) while in M pesfelis these ribs are
irregularly arranged (Figs 3-5). Only in size of 13 mm
M. pesfelis (Figs 6-7) show well-formed primary ribs
but they are different in number and shape than those
in S. coruscans coruscans of the similar size.
Also the sculpture of auricles is different and in M
pesfelis radial and concentric sculpture are more
prominent (Figs 14-29). In the size of 13 mm
pesfelis already has one strong tubercle on the edge of
posterior auricles (5-6 in adult ones).
The series of microscopic pits which are visible in
between secondary riblets of S. coruscans coruscans
are not present in M. pesfelis.
Siletié (2004) described S. coruscans coruscans (from
Indo-Pacific region) as follows: ‘“exterior shell surface
main characteristic are: 12-15 primary tripartite radial
ribs, from which 1-2 intercostals secondary radial
riblets are formed, determining about 65 secondary
riblets and a shagreen microsculpture between the
costae”. This description agrees very well with our
specimens from Raiatea Island.
She described the single specimen from Croatia as
follows: “Our specimen of Semipallium coruscans
coruscans is 4.8 mm high and 5.2 mm long 14 radial
ribs are present, with some secondary riblets in initial
stage that however form a strongly developed
shagreen microsculpture on the lower half of the shell,
near the ventral side of the shell. The colour of the
shell is yellowish-brown, with white tinges and
blotches in the centre of the shell, and a brownish part
near the umbo, at the beginning of the auricles”. Our
specimen of 3.6 mm (Fig. 3) agrees very well with this
description.
After these observations it is obvious that the only
specimen figured by Siletié (2004) belongs to the
same species as our specimens from Mljet Island so
that the report of Semipallium coruscans coruscans
from Adriatic Sea should be considered as a
misidentification of Manupecten pesfelis.
Our conclusion is also supported by CLEMAM (2007)
and CIESM (2007): they do not report this alien
species in their lists.
We notice now that Semipallium coruscans coruscans
(Hinds, 1845) should be placed in the genus
Pascahinnites Dijkstra & Raines, 1999 as stated by
Paulay (2003).

ABSTRACT. The Morum chipolanum-group of Morum (Oniscidia) species has a long geologic
history in Tropical America, although their specimens are never abundant. Most of the original
descriptions were based on very few shells. The lack of information concerning intraspecific
variability makes classification sometimes difficult within this group of species with somewhat
conservative shell design. This study attempts to distinguish several Caribbean Neogene taxa on
the basis of combined shell morphometry and qualitative shell characteristics, paying special
attention to the distinction between the shells of M. (O.) domingense from the Upper Miocene-
Lower Pliocene of the Dominican Republic and those of the Recent M. (O.) lindae from the coasts
of Colombia and Venezuela, in order to ascertain if they should be assigned to the same or to
distinct taxa. The largest number of specimens yet considered is assembled, drawn from
adequately illustrated specimens in the literature, collections and high quality digital photographs
posted on the Internet. Analysis shows that by morphometry alone these two taxa cannot be
reliably distinguished, but when the morphometric data is considered in combination with other
observable shell characteristics the two sets of shells are most likely distinct, actually representing
NOVAPEX 8 (3-4): 111-121, 10 décembre 2007
two different taxa. This conclusion is further strengthened by palaeobiogeographical data.
INTRODUCTION
The genus Morum Rôüding, 1798, now placed in the
family Harpidae Bronn, 1849 (Hughes & Emerson,
1987) superfamily Muricoidea Rafinesque, 1815
(Bouchet & Rocroi, 2005), comprises a small group of
species of carnivorous marine gastropods (J. Smith in
Beesley ef al. 1998), occurring in tropical to
subtropical seas worldwide. They are found in shallow
to fairly deep waters, but are always uncommon to
very rare (J. Smith in Beesley er al., 1998). The
subgenus Oniscidia Môürsch, 1852 (— Cancellomorum
Emerson & Old, 1963, see Vokes, 1998) comprises a
group of Morum species with a cancellate sculpture:
for full discussion on the taxonomic problems
regarding the name Oniscidia we refer to Beu (1976)
and Vokes (1998). In this paper we will only discuss
what Vokes (1998) called the M. chipolanum-group of
species, characterized by an ornamentation of
elongated pustules on the parietal shield as opposed to
coarse rugae, as seen in Morum (“Oniscidia”) sp. from
the Middle Eocene Gatuncillo Formation (Woodring,
1959) and the Recent Brazilian M (O.) matthewsi
Emerson, 1967.
A handful of species belonging to the M. chipolanum-
group have been described from the Caribbean
Neogene and Recent faunas.
The earliest Tropical American records are for the
Peruvian M. peruvianum Olsson, 1931 from the
Eocene Chira Formation (Olsson, 1931) and for M
(O.) harpula (Conrad, 1848) from the Lower
Oligocene Vicksburg group of Mississippi, USA
(MacNeil & Dockery, 1984).
From the Lower Miocene the following species have
been reported: Morum chipolanum Dall, 1925 from
the Chipola Formation of Florida, USA and Baitoa
Formation of the Dominican Republic (see Vokes,
1998), and M. (Onicidia) jungi Landau, 1996 from the
Cantaure Formation of Venezuela (see Landau, 1996).
M. harrisi Maury, 1925, from the Lower Miocene
Pirabas Limestone of Brazil, is based on internal
moulds and its apertural features are unknown
(Maury, 1925). Morum (O.) coxi (Trechmann, 1935)

Morum (Oniscidia) domingense
Jung, 1972) Grand Bay Formation of Carriacou (Jung,
1971). In the Upper Miocene and Lower Pliocene
assemblages M. (0). domingense (Sowerby, 1850)
occurs in the Cercado, Gurabo and Mao Formations of
the Dominican Republic (Vokes, 1998).
Morum (O.) meganae Raymond, 1997 was recently
described from the Middle Pliocene Pinecrest Beds of
Florida and M. (O.) macgintyi Smith, 1937 [M. (O.)
obrienae Olsson & Petit, 1964, is almost certainly a
junior synonym of M. (O.) macgintyi (Emerson, 1967;
Vokes, 1998)] occurs in the Upper Pliocene
Caloosahatchee Formation of Florida (Petuch, 1994).
The living M. (O.) dennisoni (Reeve, 1842), found
from the coasts of Louisiana, USA south to the
Caribbean, is immediately distinguished from this
group by the larger size of fully adult specimens, by
its weaker spiral sculpture, with cords of unequal
strenght making it difficult often to distinguish cords
of primary or secondary strength. This is not the case
with any of the other species of the M. chipolanum-
group in which all the cords are more strongly
elevated and of roughly equal strength. The subsutral
ramp of the last whorl in M. (O.) dennisoni is much
wider than in any of the other members of the group
and there is a marked thickening of the inner aspect of
the outer lip mid-height in M. (O.) dennisoni not
present in the other group members. Finally the
pustules tend to be coarser in the shells of M. (O.)
dennisoni. Rios (1994) suggested M. (O.) lindae was a
synonym of M. (O.) dennisoni. At the time of
publication probably only a couple of specimens of
the latter were known, and Rios probably considered it
a subadult specimen of M. (O.) dennisoni. However,
as more material of M. (O.) lindae has become
available it is clear these differences are consistent and
not gerontic characters, as the smallest shell of A (O.)
dennisoni we have found is within the maximum size
range of M. (O.) lindae and still shows these
consistent differences.
Petuch (1981) assigned a specimen collected from 11
meters depth off the Goajira Peninsula, Colombia to
M. domingense, noting at the time that the specimens
of the species known from the fossil record had 12
axial ridges, whereas the Recent shell had 16.
Subsequently, he reassigned the Recent specimen to
Morum (Cancellomorum) lindae Petuch, 1987 (p. 95,
pl. 23, Figs 1-2). He considered M. domingense “the
direct ancestor”’ of M. lindae and noted that the fossil
species: “(...) has fewer axial ribs, is broader and
more angled, has a smaller parietal shield, and is far
less sculptured and less squamose” (Petuch, 1987, p.
95).
Vokes (1998) accepted the distinction between the
fossil and recent taxa, specifying that the number of
axial ribs in the fossil shells of M (O.) domingense
varied from 10-12 and added that: “(...) the nature of
the low stepped spire, with its incised suture and the
numerous fine axial lamellae, suggests that M. lindae
is the linear descendent of the more recently described
Cantaure Formation M. jungi Landau (1996, p. 53, pl.
2
1, Figs 1-2) rather than of M. domingense.” (Vokes,
1998, p. 20).
In all Caribbean assemblages in which Morum occurs
it is uncommon to very rare and at the time when
many of the above taxa were described, they where
known from one or two specimens only. As larger
numbers of shells have become available and the
intraspecific variability better represented, the
characteristics separating some of the taxa have
become less clear.
This paper started as a discussion over the validity of
M. (O.) lindae as a distinct taxon from the Mio-
Pliocene M. (O.) domingense. For each argument put
forward supporting their separation, a Recent shell
refuting their isolation could be found. Therefore, in
the light of the greater amount of material available,
we attempt to clarify whether M. (O.) lindae and M.
(O.) domingense are indeed distinct taxa by means of
a morphometric comparison. We have added
morphometric data on the shells of two further
undisputed extinct species, M. (O.) chipolanum and
M. (O.) jungi and the living M. (O.) dennisoni in
order to investigate the interspecific variability within
this group of gastropods with very similar shells.
Although the number of shells used in this study is
less than that usually used for morphometric studies,
we stress that for all species this is the largest number
of specimens so far available.
MATERIAL AND METHODS
Data for the fossil shells were obtained from
measurements, rib and cord counts as well as
observations of shell characteristics of the type
material clearly illustrated in Landau (1996) and
Vokes (1998) and further specimens in the Bernard
Landau collection (M. (O.) chipolanum: 10 specimens,
3 from locality TU (Tulane University locality
number) 458, 3 from TU 546, 5 from TU 826; M. (O))
jungi: 5 specimens from TU 1269, M (O)
domingense: 34 specimens, 2 Cercado Formation from
NMB (Naturhistorisches Museum Basel locality
number 16832, 32 Gurabo Formation, 2 from TU
1354, 14 from TU 1215, 13 from TU 1219, 3 from TU
1373).
The shells of some Morum (Oniscidia) species display
a considerable variation in size between fully adult
specimens, herein interpreted as shells with a fully
expanded parietal shield and thickened outer lip. In AM.
chipolanum, for example, adult shells range from 22.2
mm to 38.8 mm, M. (O.) domingense from 20.5 mm to
35.8 mm, adults of M. (O.) jungi seem more uniform
in size. For the purpose of this study we have not
included any adult specimen smaller than 23.5 mm in
height.
Data for Recent shells of M. (O.) lindae were
collected from three specimens in the Franck Frydman
collection and a further 13 shells illustrated on the
Internet (Femorale, 7 specimens; Jaxshells, 3

mineralislamacla, 1 specimen). M. (O.) dennisoni data
was collected from the Internet (Femorale 8). Only
specimens 1llustrated with both ventral and dorsal
views and with the correct standard orientation were
considered. Whilst collecting data from images on the
web may not usually be ideal, we suggest that for rare
specimens such as this (the type material consists of
the holotype alone) it is a useful way to consider the
maximum number of specimens known. For this study
internet data was collected from the following sites:
Guest Shells (1996), Frank (1998), Coltro
(2006); worldwideconchology.com (2006).
Measurements were taken as illustrated in Figure 1.
Measurements of Internet photographs were taken
with the measuring tool after copying the pictures into
Photoshop, thereafter measurements calculated based
on the original length given for each specimen. To
minimize observer error all measurements were taken
by the first author.

RESULTS
Several specimens of the fossil taxa M. (O0)
domingense and M. (O.) chipolanum, and one Recent
shell of M. (O.) lindae had their protoconchs well
preserved. In all three the protoconch was small,
consisting of 1.25-1.5 smooth whorls with a small
nucleus. This small paucispiral type of protoconch is
highly suggestive of non-planktotrophic larval
development. Bouchet (2002) reviewed data on Indo-
Pacific Morum species and concluded that
planktotrophy was the standard method of
development in these species. He also noted that all
the Caribbean species; M. lindae, M. domingense, and
M. dennisoni had paucispiral protoconchs. It therefore
seems that unlike the Indo-Pacific species, in the
Caribbean non-planktotrophic development is the
norm. This coincides with the type of development
observed in the living western Atlantic species Morum
oniscus (Linnaeus, 1767) (type species of Morum),
which lays its eggs beneath small slabs of coral at low
tide level. The eggs undergo direct development and
the gastropods hatch as crawling young (Work, 1969).
Protoconch morphology was not, therefore, useful in
distinguishing between species within the
chipolanum-group.
Morphometric results on the teleoconch show:
1. In relation to their overall shape, there is overlap
between the specimens of four species when
comparing width in relation to height, although

DISCUSSION
It is clear from the results above that by this
morphometric assessment alone it is not possible to
distinguish groups of specimens easily within this
assemblage of taxa with highly conservative shell
form. Our plots show that M. (O.) domingense tends to
have a narrower shell than M (O.) lindae, M. (O.)
chipolanum tends to have the broadest parietal shield,
that M. (O.) jungi has consistently fewer axial ribs
116
than M. (O.) lindae, and M (O.) lindae has
consistently fewer spiral cords than M (O0)
chipolanum while tending to have fewer cords than M.
(O.) domingense and M. (O.) jungi.
Two further shell features are important 1m
distinguishing the four groups of shells, which are not
amenable to morphometric analysis: These are the
shape of the parietal shield and the degree of
development of secondary scabrous or squamous
sculpture formed by the axial growth lines. Morum
B.M. LANDAU, F. FRYDMAN & C.M. DA SILVA
(Oniscidia) chipolanum and M. (0O.) jungi both have a
shield which is rounded adapically, whereas in M. (O.)
domingense and M. (O.) lindae the shield is somewhat
pointed in the area of the posterior canal (see Plate 1).
This character does not seem too variable
intraspecifically.
The second, the surface scabrosity, is difficult to
quantify. There is no doubt that M. (O.) chipolanum
has the most scabrous surface and M. (O.) domingense
the least. Whilst some intraspecific variability exists,
the most scabrous specimen of M. (O.) domingense
(Plate 1, Figure 4) is still less scabrous than the
smoothest M. (O.) chipolanum. Morum (O.) lindae
usually has a more scabrous surface than M. (O.)
domingense, although in the occasional specimen
(Plate 1, Figure 4) there is little difference between
them.
Vokes (1998) discussed a further character, the spire
and considered M. (O.) lindae to have a more stepped
spire than M. (O.) domingense. As can be seen from
the specimens illustrated (Plate 1) and the plot of
(apertural height/height)/height (Figure 3) there is no
difference in relative spire height between the three
species and only M. (O.) jungi has à significantly
more stepped spire, 1.e. the infrasutural platform is
more horizontal.
PALAEOBIOGEOGRAPHIC
CONSIDERATIONS
The present Caribbean region in the Miocene and
Pliocene was part of the larger palaeobiogeographical
Gatunian Province, which straddled the present day
region of the Isthmus of Panama and included the
modern Caribbean region and Tropical American
Pacific (Woodring, 1974; Vermeij, 2005). The closure
of the Central American Seaway (CAS) divided the
Gatunian Sea, causing a significant change in the
faunal composition on the Atlantic side. After the total
closure of the CAS the Atlantic portion of the
Neogene Gatunian Province gave rise to the Recent
Caribbean Province. The Neogene Gatunian Province
is characterized by a relative stability of gastropod
taxa at generic level, but a very rapid turnover at
specific level (Landau ef al., in print PPP). These high
rates of extinction and local disappearance are
accompanied by high rates of speciation (Allmon et
al., 1993; Jackson ef al., 1993). At species level it is
not unusual to have an extinction rate since the Early
Pliocene to present times of 80-85% (Woodring, 1928;
Jung, 1969, Landau et al., in press), with about half
the long-lived taxa belonging to the most notoriously
cosmopolitan group of gastropods, the tonnoideans
(Beu, in prep).
Within the Gatunian Province, Morum (Oniscidia)
domingensis is found exclusively in the West Indian
Subprovince of Woodring (1974). The northern
Caribbean coasts of South America formed the
Colombian-Venezuelan-Trinidad Subprovince of
Woodring (1974). At specific level, the assemblages
NOVAPEX 8 (3-4): 111-121, 10 décembre 2007
found in the West Indian and Colombian-Venezuelan-
Trinidad Subprovince share very few taxa in common.
Despite extensive collecting in rich Pliocene
sediments in the area, there are no reported
occurrences of M. (O.) domingense in the fossil record
of the Colombian-Venezuelan-Trinidad Subprovince.
Morum (O.) lindae occurs exclusively off the
Caribbean coast of Colombia and Venezuela. As in
the Neogene, the fauna of the northern coasts of South
America contains a high number of endemic elements
(Petuch, 1987; Diaz, 1995). Indeed, Landau ef al. (in
print PPP) argued that the Colombian-Venezuelan-
Trinidad Subprovince was probably in place since at
least the Early Miocene and has continued as a distinct
palaeobiogeographical unit to the present day.
Although Petuch (1982) argued that this area had
acted as a refugium for Gatunian species unchanged
since the Pliocene (a primary relict pocket, according
to his nomenclature), this does not stand up to
taxonomic scrutiny. Petuch (1988) later considered it a
secondary relict pocket, i.e. containing species which
closely resemble their Pliocene ancestors. There is no
fossil record of M. (O.) lindae in the southern
Caribbean assemblages. Only one single fragment of
Morum (Oniscidia) sp. from the Lower Pliocene Punta
Gavilän Formation, Falcon Province, mainland
Venezuela, is known (BL collection), and it is too
incomplete to identify specifically.
CONCLUSIONS
Using a combination of quantitative shell parameters
and qualitative shell characters of shield shape and
scabrous surface one can conclude that M. (O.)
chipolanum is most clearly distinguished from its
congeners by the round shape of its shield and
strongly scabrous surface. Morum (O.) jungi 1s
characterized again by its abapically rounded shield,
although less expansive than in the previous species
and in having consistently fewer axial ribs than its
congeners. Morum (O.) domingense and M. (0O.)
lindae are less easily distinguished; M (O)
domingense tends to have a more elongated shell,
fewer axial ribs as well as a greater number of primary
spiral cords and also tends to have a smoother surface
although there is some overlap with all these features
between the two taxa. Apertural height, spire height
and shield width are not useful to distinguish the
shells of the two species.
On the basis of protoconch morphology all members
of the M. chipolanum-group, in which the protoconch
is known, have a small paucispiral protoconch, which
strongly suggests a non planktotrophic larval
development. This type of development is commonly
associated with species having a shorter geological
longevity and a more restricted geographical
distribution (Jablonski & Lutz, 1980; Scheltema,
1989; Gili & Martinell, 1994), which might support
the separation of the two taxa. However, this does not
seem to be universally true across all gastropod
117
B.M. LANDAU, F. FRYDMAN & C.M. DA SILVA
Morum (Oniscidia) domingense
groups, as Jackson ef al. (1996) found no correlation
between species longevity and inferred developmental
modes in Neogene Tropical American strombinids.
Whilst M. (O.) domingense and M. (O.) lindae show
very similar shells, on the basis of our present
knowledge of the Caribbean faunal turnover and the
biogeography of the Neogene Atlantic Gatunian
faunas it would be very unlikely for an exclusively
Upper Miocene-Lower Pliocene Gatunian West Indian
species to occur today within the Colombian-
Venezuelan-Trinidad Subprovince.
Taking all the above arguments into consideration it is
most likely that M (O.) domingense and M. (O.)
lindae actually represent two distinct taxa. There is
insufficient evidence to suggest a direct lineage
between the two based on their shell morphology and
palaeobiogeographic distribution. Further information
on the Morum (Oniscidia) species present in the
Lower Pliocene Punta Gavilän Formation of
Venezuela might help to clarify the relationship
between these members of the M. chipolanum-group
in the southern Caribbean.

INTRODUCTION
During about ten years (from 1976 to 1986), the
Rijksmuseum van Natuurlijke Historie (National
Museum of Natural History) in Leiden led the
CANCAP-project, a large programme of
biogeographically oriented marine research in the
south-eastern part of northern Atlantic. Seven
campaigns (CANCAP-I to VII) were carried out,
visiting a large area covering Azores, Madeira
Archipelago, the Moroccan shelf, Canary Islands,
Mauritanian coasts, Senegal and the Cape Verde
Islands. Van der Land (1987) listed the stations of the
whole CANCAP-project. These campaigns have
brought an interesting material of highly scientific
interest, among others various trochids species. Some
of them were Calliotropis species and have been
studied in a more general work upon this genus in the
central eastern Atlantic (Vilvens & Swinnen, in press).
Other species were Solariellidae, and we found among
them a specimen from the Azores that seems to be
unknown. Closer examination and comparison with
other species from this area lead us to conclude that
this shell belong to another new species that is
described here.

SYSTEMATICS
We follow here the classification of Bouchet & Rocroi
(2005), where former Solariellinae, earlier treated as a
subfamily of Trochidae (Hickman & McLean, 1990),
are now ranked as a family of the superfamily
Trochoidea.

Distribution. Azores, east of
30°52'W, 1874-1887 m.
Diagnosis. A high-spired So/ariella species with
conical shape, whitish, with 2 main spiral cords and
numerous thin spiral cords on spire whorls, the
adapical the strongest; abapical main cord obsolete on
last whorl; base with numerous spiral cords and an
inner granular cord around the broad umbilicus.
Description. Shell rather tall for the genus (height up
to 9.7 mm, width up to 8.4 mm), higher than wide,
rather thin, conical; spire high, height 1.15x width,
3.6x aperture height; wide umbilicus.
Protoconch of 400 um, of 1 whorl, smooth, without
visible terminal varix.
Teleoconch up to 5.7 convex whorls, bearing up to 20
spiral granular cords and thin prosocline ribs; nodules
from cords produced by intersections with axial
threads. Suture impressed, slightly canaliculated. First
whorl convex, immediately sculptured by 6 thin,
evenly spaced spiral cords; PI granular, P2 and P3
subgranular, P4, PS and P6 smooth; half a whorl later,
P2 and P3 granular and P4 subgranular; weak, almost
indistinct, axial thin ribs; ribs stronger at end of whorl,
thicker in their adapical part; interspace between ribs
3x broader than ribs. On second whorl, all spiral cords
granular; Pl stronger than other cords, with thick
beads; P6 sinking into suture and disappearing;
secondary cords S1 and S4 appearing. On third whorl,
PI strongest, producing subsutural horizontal ramp,
with beads becoming sharp, oriented at 75°; P4
weaker than PI but stronger than other cords,
producing a second keel at second third of whorl;
axial ribs visible all around the whorl, prosocline,
thicker than on preceding whorl, interspace between
ribs about 2x broader than ribs. On succeeding whorls,
additional thin spiral cords appearing by intercalation
between existing cords, more visible between P4 and
P6; axial ribs still rather thick above P4, much thinner
under it; subsutural ramp becoming oblique. On last
whorl, all spiral cords weak except PI strong with
sharp, isolated nodules; cords hard to count, about 20;
keel at P4 disappearing.
Aperture circular; peristome almost complete; outer
and inner lip rather thin. Columella curved, with a
weak median thickening, without tooth.
Base moderately convex, with about 10 spiral cords,
innermost much stronger, with sharp beads, bordering
umbilicus: distance between cords similar in size to
cords; thin axial ribs between cords, thinner than
cords, distance between from 1x to 1.5x size of ribs.
Umbilicus broad, diameter about 30% of shell width,
funnel shaped with gently sloping walls, with about 8
thin, granular spiral cords and thin axial lamellae
inside.
Colour of protoconch and teleoconch off-white.
Discussion. Solariella cancapae n. sp. is rather close
to S. amabilis (Jeffreys, 1865) (Figs 7-12) from
North-western European Atlantic [(from Iceland and
Norwegian to off Morocco (Sneli et al., 2005)], but
this species, rather variable regarding the height of
the shell but never recorded from the Azores, is much
smaller, has three, not only one, strong spiral cords
making keels on last whorl, much thinner, indistinct
spiral cords on the base with an innermost much
thicker spiral cord around the umbilicus, and less
numerous spiral cords (up to 5) inside the umbilicus.
The combination of an elevated shell, a strong spiral
cord PI with sharp beads and a prominent second keel
on spire whorls may remember S. multirestis Quinn,
1979 from Lesser Antilles and Florida Keys, but this
similar in size species has the main spiral cords of
same strength, no keel at second third of the spire
whorls and stronger, only 7, spiral cords on the base
(see Quinn, 1979 for an illustration).

From the same Azores area, the new species may also
be compared to S. azorensis (Watson, 1886) (Figs 3-
6), but this similar in size species has a less elevated
spire with a ratio H/W about 1, adapical granular
spiral cords on whorls aligned along prosocline axial
ribs and abapical ones smooth on last whorl, and a
thick funicle partly filling the umbilicus (this feature
lead us to think that this species could be moved from
the genus So/ariella to the genus Ethalia Adams &
Adams, 1854, or related Rossiteria Brazier, 1895).
S. cancapae n. sp. is also superficially similar to
Haloceras carinata (Jeffreys 1883) (Vanikoroidea)
(Figs 13-14), former known as S. constricta Dall,
1927 and Cithna carinata Jeffreys, 1883 (Waren &
Bouchet, 1991 and 1993) from northern Atlantic (from
southern Georgia to southern Florida and from off
Portugal to Madeira), but this much smaller species
has more convex whorls, a thinner subsutural beaded
spiral cord if present, and a much narrower umbilicus.
Etymology. Of CANCAP (Latin) — after the
CANCAP campaigns that brought this species to our
knowledge.

ABSTRACT. Three new gastropod species from deep-water, southeastern Gulf of Mexico are
described: Calliostoma frumari in the family Calliostomatidae; and Canalispira kerni and C. lipei
in the family Cystiscidae. They are compared with their congeners.
INTRODUCTION
Deep-water dredgings in the Gulf of Mexico have
brought to light a number of new species of small
cryptic mollusks that have been described in recent
years. While these species were collected due to the
availability of grants and research ships, amateur
collectors have also been doing their part with perhaps
less sophisticated methods, such as making fishermen
aware of the smaller, less marketable species, or by
the collector himself, who spends time and money to
0 after the deeper-water material.
Two of the new species treated in this study,
Calliostoma frumari and Canalispira kerni are the
result of private deep-water dredging operations off
the southwestern coast of Key West, Florida by Frank
Frumar, an ardent shell collector and dredging
enthusiast, and Steve Kern, a commercial lobster
fisherman from Key West, Florida, owner of the
dredging boat. Specimens of the third species,
Canalispira lipei, were obtained by Robert Lipe, of St.
Petersburg, Florida by contacting fishermen who
operated in the Yucatan area.
The genus Canalispira Was poorly understood by the
malacological community until Coovert & Coovert
(1995) published their monograph on marginelliform
gastropods. The genus was further readdressed by
McCleery & Wakefield (2007) when the authors also
described three new species. Until recently only two
western Atlantic species had been assigned to
Canalispira: Hvalina styria var. minor Dall, 1927,
inhabiting deep water off Georgia and northeastern
Florida, and Prunum hoffi Moolenbeek & Faber 1991,
found in the island of Saba, Netherland Antilles. Since
then, five new species of Canalispira have been
described: the Cuban species Osvaldoginella gomezi
Espinosa and Ortea, 1997: 141-145, later placed in
Canalispira by McCleery and Wakefield (2007: 2); C.
aurea Garcia, 2006, dredged in Bahia de Campeche,
Mexico; and the Central American species C.
phantasia McCleery & Wakefield, 2007, C. ornata
McCleery & Wakefield, 2007, and C. fluctuata
McCleery & Wakefield, 2007. Canalispira kerni n. sp.
is only the second species assigned to this genus to be
found in the United States. The second Canalispira
described here, C. lipei, has originally appeared in
publications as “Volvarina” sp. (Lipe & Sunderland,
1991:15), and “Marginella” sp. (Lipe, 1991: 14, pl. 7,
figs 8 and 9; and back cover). In both publications the
stated locality is “Florida”. However, this is in error
(Robert Lipe, pers. comm.), as the confirmed locality
for the species is off Contoy Light, northeastern
Yucatan Peninsula, Mexico. The corrected locality
appears in an errata sheet sent by Mr. Lipe with later
copies of his booklet Marginellas.
The genus Calliostoma has not seen the surge of
publications that Canalispira has received. Since
Quinn’s publication in 1992 in which he described 27
new species of western Atlantic Calliostoma sensu
lato, only Calliostoma magaldii Caldini & Prado,
1998, a species from Chubut Province, Argentina, has
been described. Presumably, the new species proposed
here may have been overlooked because of its small
size and deep-water habitat.

Type locality. 24°14°N, 82°09°W: approximately 37
kms southwest of Key West, Florida, in 200 m.
Distribution. Known only from the type locality
Description. Holotype 7.7 mm in width (Figs 1-4),
light in weight, strong, widely umbilicate, widely
trochoid (width/ height ratio 0.75). Protoconch
translucent white, smooth, of about one whorl.
Teleoconch of 6 whorls; first whorl with carinated
shoulder; shoulder narrowing on second whorl,
disappearing on later whorls; profile of whorls slightly
convex in early whorls, becoming progressively
straight. Suture channeled, bordered on both sides by
rows of bead. Axial sculpture appearing immediately
after termination of protoconch; about 29 slightly
nodulose axial threads on first whorl; nodes becoming
stronger, forming well-defined rounded beads on
following whorls; axial ornamentation increasing in
number on later whorls; approximately 62 axially
aligned rows of beads on last whorl. First spiral
pattern showing as nodulose carina on first whorl; a
second abapical thread appearing towards end of first
whorl; three adapical axial nodes showing obvious
spiral alignment by middle of second whorl; second
whorl terminating with 5, evenly spaced spiral rows of
beads; number of rows remaining constant on
following 3 whorls; rows increasing incrementally in
size abapically; sixth narrower cord appearing
abapically on last whorl, creating slight carina at base
of shell; a thin spiral thread appearing between fourth
and fifth cord; all shell beads connected by spiral
thread only. Base of shell only slightly convex at
border, becoming concave approximately mid-way to
umbilical area (Fig 2), ornamented with 9 spiral cords;
peripheral cords slightly nodulose, nodes increasing in
strength on subsequent cords. Periphery of umbilicus
delineated by a wide, strong cord of axially elongated
beads (Fig. 3); umbilicus wide, 24% of maximum
shell diameter, smooth within, funnel-shaped, deep,
reaching apical whorl. Aperture sub-quadrate; lip thin;
Figures 1-8
columella with one prominent denticle at periphery of
umbilicus and a second, smaller denticle slightly
posterior to elongated umbilical beads (fig. 3). Shell
nacreous.
Discussion. Marshall (1995: 385) established the
value of the development of early spiral ornamentation
in Calliostomatidae in discriminating species-group
taxa. The ontogeny of spiral elements in Calliostoma
frumari have been carefully described above. The new
species has 5 primary cords from second to fifth
whorls, with a sixth primary cord at the periphery of
the last whorl. The thin thread showing between the
fourth and fifth spiral cords on the last whorl is not
consistent with ornamentation of the paratypes and
seems to be of sub-specific value.
The nacreous shell, widely trochoid shape, and large
umbilicus separate this species from other western
Atlantic Calliostoma. Two American species are
somewhat similar. Calliostoma aulicum Quinn, 1992,
a species from the Caribbean coast of Panama, has a
narrower umbilicus (17%- 20% of maximum shell
diameter), grows to 16.1 mm in width, has different
markings, and a spiral ornamentation of 2 to 3spiral
cords on first two whorls, increasing to 10 to 12 on
last, abapical three strongest. Calliostoma argentum
Quinn, 1992, which inhabits Yucatan waters, also has
a narrower umbilicus (14%- 17% of maximum shell
diameter), grows to 28.2 mm, has a light tan shell with
pale orange-brown patches and spots on periphery,
and a spiral sculpture of 2 to 3 spiral cords on first two
whorls, increasing to 9 to 11 on last whorl.
The widely trochoiïd profile, the nacreous shell, the
strong denticles in the aperture, and large umbilicus of
Calliostoma frumari have strong similarity to
characters of Ancistrobasis costulata (Watson, 1859),
and À. depressa (Dall, 1889) species inhabiting the
Florida Straits and the Yucatän Channel. À. costulata
grows to only 3.6 mm and has a more globose shell. À.
depressa grows to 5 mm and has a width/ length ratio
of 0.5. Both species have approximately twice as
many spiral cords on whorls and have been assigned
to Seguenziidae (Quinn, 1979: 50).
Etymology. Named for Mr. Frank Frumar, of
Kirkwood, Missouri who, together with Steve Kern,
collected the shells and donated the type material.

conform in characters with those of the holotype:
Figures 9-20
however, the yellowish markings are difficult to see in
some specimens due to fading.
Of the seven western Atlantic species assigned to
Canalispira, C. kerni n. sp. is most similar to
Canalispira minor (Dall, 1927) (Figs 10-12), a species
inhabiting deep water off the east coast of the United
States; however, the latter is smaller, relatively wider
(width/ length ratio 0.43), lacks the swollen area at the
shoulder of the last whorl (Fig 11), and is solid white.
The ‘“numerous specimens” inspected by Dall are
“very uniform in character’(1927:46). Dall’s
specimens were collected in more than twice the depth
of Canalispira kerni. Although Dall (1927: 46) and
Kaicher (card No. 6204) establish the length of the
syntype (USNM 107982, Figs 10-12) as 6 mm, the
SEM image of the syntype shows a length of 4.6 mm.
The Central American species Canalispira phantasia
McCleery & Wakefield, 2007, C. ornata McCleery &
Wakefield, 2007, and C. fluctuata McCleery &
Wakefield, 2007 live in shallow water (1- 15 m),
grow to less than 4 mm in length, have four
columellar plications, have a width/ length ratio of
0.47 to 0.50, and are differently marked. Canalispira
gomezi (Espinosa & Ortea, 1997), a relatively deep-
water species from northern Cuba, grows to 3 mm, has
a shorter apex, and is differently marked. Canalispira
hoffi (Moolenbeek & Faber 1991) from Saba, Dutch
West Indies, grows to 3.6 mm, has 4 columellar
plication, is proportionately wider, and has different
markings. Canalispira aurea Garcia, 2006 from Bahia
de Campeche, southwestern Gulf of Mexico, is
proportionately wider, has a shorter spire, four
columellar plications, and is differently colored.
Two species of Dentimargo may be confused with
Canalispira kerni because of their cylindrical- biconic
shape and small size: Dentimargo idiochila
(Schwengel, 1942), a Floridian species, has four large
columellar plications and a solid coloration with a
white subsutural band; and Dentimargo smithii (A. E.
Verrill, 1885) also has four columellar plications, is
brownish in color, and is proportionately wider.
Moreover, these two taxa lack the deeply channeled
posterior sulcus characteristic of Canalispira.
There is a Floridian Volvarina, V. redfieldii (Tryon,
1882) that resembles the new species, but the former
grows to 8 mm, has four columellar plications, and
has a solid coloration.
Etymology. Name for Mr. Steve Kern, of Key West,
Florida, who, together with Frank Frumar, collected
the shells and donated the type material.

Type locality. ENE of Contoy Light, northeastern
Yucatän Peninsula, E. Mexico, 75-130 m.
Distribution. Known only from the type locality
Description. Holotype 6.2 mm in length (Figs 13-17),
thick, shiny, conically oblong (width/ length ratio
0.35), slightly depressed dorso-ventrally (2.7 mm in
width vs. 2.5 mm in height). Protoconch paucispiral,
dome-shaped, ivory white. Teleoconch ivory white,
ornamented with a vellowish-orange webbing pattern,
sometimes creating triangular shapes with angle
pointed adaperturally, and irregular, larger
maculations that tend to form bands at shoulder and at
mid-body (Fig 16). Aperture ivory white, tinged with
yellowish-orange at tip of anterior notch (Fig 17),
approximately two thirds of shell length, narrow
posteriorly, conspicuously widening after midsection.
Outer lip without varix, slightly thickened posteriorly,
thinning as aperture expands, slightly incurved at
midsection; posterior notch deep, narrow. Columella
with 4 simple, evenly spaced, oblique plications (Fig
17); first plication slightly weaker, positioned about
midsection on parietal wall; anterior plication longest,
continuing to, and blending into, anterior end of
aperture.
Discussion. The pattern of maculation of each of the
Il specimens studied is different (Figs 18-20);
however, all other characters of the holotype are
present in the paratypes. Their average length is 5.76
mm; the smallest, paratype 7 (Fig 20),measures 5.4
mm; the largest, paratype 9, measures 6.6 mm. Their
width is rather consistent at approximately 2.7 to 2.8
mm.
Of the 7 western Atlantic species assigned to
Canalispira, the new species has the most affinity
with C. aurea Garcia, 2006, a species that inhabits
Bahia de Campeche, southwestern Gulf of Mexico;
however, the latter is solid orange in coloration with a
thin white band by the suture, is smaller, is generally
wider (width/ length ratio 0.52) and has differently
structured columellar plications. Canalispira hoffi
(Moolenbeck & Faber, 1991) grows to only 3.6 mm, is
wider (width/ length ratio 0.5), has brown-tented
markings, and apertural denticles. Canalispira
phantasia McCleery & Wakefield, 2007, C. ornata
McCleery & Wakefield, 2007, and C. fluctuata
McCleery & Wakefield, 2007 live in shallow water
(1- 15 m), grow to less that 4 mm in length, and are
differently marked.
Etymology. Named for Robert Lipe, of St. Petersburg,
Florida, a marginelliform enthusiast, author of the
booklet Marginellas, and donor of the holotype and
two paraypes.

Mercenaria mercenaria Linnaeus, 1758 est un Veneridae originaire de la Côte Est de l’ Amérique du Nord. Il est
présent de la Nouvelle-Ecosse (Canada) jusqu’au Yucatan (Mexique). Dans certaines régions, il est
commercialement exploité pour la consommation de sa chair. L’espèce a été introduite dans certains estuaires
des côtes européennes à des fins d’élevage. Les tentatives de conchyliculture n’ont jamais fait l’objet d’un succès
particulier, cependant quelques populations implantées sont recensées en Angleterre (Solent), aux Pays-Bas
(Zélande) et en Belgique (Port d’Oostende) (Tebble 1966). En France, sur la façade atlantique, des populations
sont présentes dans le golfe du Morbihan (Rivières du Bono et d’Aurey) et en Charente-Maritime (estuaire de la
Seudre) sur des fonds sablo-vaseux, jusqu’à quinze mètres de profondeur (Ifremer 2007). On signale aussi la
présence de l’espèce au Portugal, en Espagne (Atlantique), en Adriatique septentrionale et en Sicile (Quéro &
Wayne 1998).
Un spécimen vivant de Mercenaria mercenaria a été trouvé dans les résidus de triage d’un trait de dragage
d’huîtres plates (Ostrea edulis Linnaeus, 1758) dans le port ostréicole / mytilicole du Vivier-sur-Mer, en mars
2007. Le banc d’huîftres échantillonné se situe par 10 mètres de profondeur en pleine eau dans la zone
sublittorale de la baie du Mont-Saint-Michel.
Taille de l’animal : 85,4 x 75,5 mm (Fig. 1). Le spécimen est de taille largement supérieure à ceux déjà en notre
possession et achetés en poissonnerie de Perros-Guirec (mars 2003) provenant d’un lot étiqueté (Ria d’Etel -
Morbihan) - 71,8 x 58,1 mm (Fig. 2).
Des populations éparses, autres que celles citées dans la littérature, existent le long des côtes atlantiques de
France. La récolte de Mercenaria mercenaria sur les fonds sablo-vaseux de la baie du Mont-Saint-Michel révèle
l’existence d’une population de ce bivalve dans la Manche au nord de la Bretagne.

RESUME. Diverses publications signalent la présence de Ocinebrellus inornatus (Récluz, 1851) le long des
côtes atlantiques françaises. La récolte d’un spécimen vivant en Baïe du Mont-Saint-Michel confirme la présence
de l’espèce en Manche.
ABSTRACT. Some publications mention the presence of Ocinebrellus inornatus (Récluz, 1851) along the
Atlantic coasts of France. The gathering of a living specimen in the Mont-Saint-Michel Bay confirms the
presence of the species into the Channel.
INTRODUCTION
Ocinebrellus inornatus (Récluz, 1851) est un Muricidae repris sous ce genre dans la plupart des articles publiés à
ce jour. Houart et Sirenko (2003) considèrent cependant qu’il faut le placer dans le genre Ocenebra. Le but ici
n’est pas de discuter du classement générique de l’espèce, de ce fait, comme pour tous nos articles, nous suivrons
la classification de CLEMAM en utilisant le genre Ocinebrellus.
O. inornatus est originaire du nord-ouest du Pacifique [Russie (Iles Sakhaline et Kouriles), Chine, Corée et
Japon]. Il accompagne bien malgré lui des transferts de populations de Crassostrea gigas (Thunberg, 1793)
d’une région du monde à l’autre. On signale son apparition sur la côte nord-ouest des Etats-Unis et du Canada,
en bordure de l’océan Pacifique: Etat de Washington (1924), Colombie-Britannique (1931), Oregon (1934) et
Californie (1941) (Bouget et al. 2001). O. inornatus apparaît pour la première fois en France dans le bassin
ostréicole de Marennes-Oléron en 1995 (Pigeot et al. 2000). Par la suite, sa progression vers le Nord se confirme
par des récoltes dans le nord de la Vendée - port ostréicole des Brochets - (Delemarre 2004) et en Bretagne-Sud -
zone ostréicole de la baie de Quiberon - (Bouget et al. 2001). Un exemplaire vivant a aussi été collecté dans une
laisse de mer à Pirou-Plage - zone ostréicole du Cotentin - (Wimart-Rousseau 2004).
O. inornatus partage la niche écologique et le mode de prédation de son cousin autochtone Ocenebra erinaceus
(Linnaeus, 1758). On le trouve dans la zone de balancement des marées et également en eaux plus profondes
(Bouget et al. 2001). C’est un redoutable prédateur de bivalves. Les concentrations de Crassostrea gigas dans les
zones ostréicoles en font une de ses proies privilégiées. O. inornatus perce la coquille des huîtres (Fig. 5) par
l’action combinée de la radula et d’une glande de forage, il aspire ensuite les parties molles du mollusque à
l’aide de sa trompe. Sa prédation sur C. gigas peut être économiquement importante. Les pontes, composées de
sacs ovigères contenant plusieurs œufs sont déposées au printemps sur des substrats durs (Fig. 6). Il n’y a pas de
stade larvaire pélagique. En conséquence, leur dispersion dans le milieu environnant reste limitée.
Des études génétiques basées entres autres sur l’analyse de l’ ADN mitochondrial ont montré que les populations
françaises et américaines d’O. inornatus étaient fort similaires, bien que non identiques, et substantiellement
différentes des populations natives asiatiques. Si la population source à l’origine de celle qui s’est développée en
France provient bien des Etats-Unis, il n’est pas exclu que des introductions non contrôlées ni répertoriées en
provenance d’Asie aient également eu lieu (Martel et al. 2004a). L'expansion de l’espèce vers le nord ne semble
pas être le résultat d’éléments fondateurs nouveaux mais réside bien plus dans le fait de mouvements de
populations de C. gigas entre les différentes fermes ostréicoles des côtes atlantiques de France (Martel et al.
2004b). Les transferts de naissain ou d’adultes étant pratiques courantes entre la côte atlantique de Vendée -
Charente et l’ouest de la Manche, il n’est pas étonnant de voir apparaître l’espèce dans le Cotentin (Wimart-
Rousseau 2004).
Les différences morphologiques de la coquille existant entre les deux espèces - ©. inornatus et O. erinaceus
(Fig. 3) - sont largement décrites et illustrées par Delemarre (2004).

RECOLTES PERSONNELLES
Dans la baie du Mont-Saint-Michel (Carte 1), sur près de 1.000 ha
de concessions en pleine mer, les ostréiculteurs sèment le naïissain
d’huîtres plates - Ostrea edulis Linnaeus, 1758 - par une dizaine
de mètres de fond. Au terme de deux à trois ans de grossissement
les huîtres sont récupérées pour être commercialisées. Cette
opération se fait à la drague, à bord de chalands amphibies qui
font l’originalité de la baie (Fig. 7). Le 18 mars 2007, dans le port
ostréicole / mytilicole du Vivier-sur-Mer, un container en attente
d’être vidangé contenait les résidus de triage d’un récent trait de
drague effectué dans la baie.
Parmi de nombreuses coquilles vides de C. gigas on pouvait identifier la présence de spécimens vivants d’Ostrea
edulis (échappés au tri), Pecten maximus (Linnaeus, 1758), Mytilus edulis Linnaeus, 1758, Glycymeris
glycymeris (Linnaeus, 1758), Venus verrucosa Linnaeus, 1758, Ruditapes philippinarum (Adams & Reeve,
1850) ainsi qu’un spécimen vivant de Mercenaria mercenaria Linnaeus, 1758 (Delongueville & Scaillet 2007).
Parmi tous ces bivalves se trouvait un seul exemplaire de gastéropode: un spécimen operculé d’Ocinebrellus
inornatus (Récluz, 1851) (Fig. 1 - 2). Taille de l’animal: 45,8 x 27,6 mm. Quoique moins colorée, la coquille est
en tout point semblable à celle d'individus collectés par nos soins en mai 2001 dans un parc à huîtres creuses (C.
gigas) de Saint-Trojan à Oléron (Fig. 4).
Le spécimen récolté au Vivier-sur-Mer provient d’un banc d’O. edulis situé en pleine eau, dans la zone sub-
littorale. Quelle peut bien en être son origine ? Le naissain utilisé pour l’ensemencement de l’huître plate en Baie
du Mont-Saint-Michel est capté naturellement en Baie de Quiberon sur des boudins garnis de coquilles de moule
vides. Une population d’O. inornatus a été localisée dans ce territoire (Bouget et al. 2001). Aurait-elle eu accès
au naissain d’O.edulis ? Le naissain de l’huître creuse (C. gigas) est quant à lui récolté sur des tuiles chaulées et
les jeunes coquilles sont placées rapidement en poches à mailles fines dans lesquelles elles entament leur
grossissement. On peut imaginer qu’à ce stade, ou peut-être plus tardivement, lorsque les poches sont placées sur
tables (donc non loin du sol), des spécimens d’O. inornatus parviennent à peupler la culture. Tout au long de leur
croissance les huîtres sont plusieurs fois manipulées, triées et nettoyées. Malgré toutes ces manipulations qui
garantissent la propreté de la production, force est de constater que des spécimens d’©. inornatus, probablement
des juvéniles, parviennent néanmoins à passer inaperçus et à donner souche à des populations indésirables.
Enfin, restent à identifier les éventuels flux d’échanges existant entre les parcs à huîtres de Charente dans
lesquels ©. inornatus est déjà bien implanté et ceux de la Baie du Mont-Saint-Michel. II serait aussi intéressant
d’objectiver la présence d’O. inornatus en Baie du Mont-Saint-Michel dans la zone d'élevage de l’huître creuse
située sur l’estran, avant la zone des bouchots et donc bien plus haut que la ligne de marée basse de vives eaux.
CONCLUSION
Ocinebrellus inornatus déjà établi en Atlantique (Charente-Maritime) semble bien s’adapter aux conditions
écologiques de la Manche comme en témoignait déjà sa présence dans le bassin ostréicole du Cotentin. La
récolte d’un individu vivant, au Vivier-sur-Mer, atteste de l’existence d’une population en baie du Mont-Saint-
Michel. Les importations de naissain ou les échanges d’adultes entre les différentes zones ostréicoles de
l’ Atlantique et de la Manche sont à l’origine de l’établissement de ces nouvelles populations.

En ce jour ensoleillé du 9 février 2007 je me suis rendu chez Pierre afin d'en ramener les préparations que bon
nombre d'entre-nous auront dégusté lors de notre Assemblée Générale, car c'est aussi Pierre qui nous fourni
souvent les délicieux amuse-bouches pour nos drinks. Ce jour-là, Pierre m'a emmené dans ses caves où ce petit
monde se nourrit, se cajole, se trémousse et se reproduit pour le plus grand bonheur de nos papilles gustatives.
J'en ai ramené un petit reportage photos que je vous livre ci-après.

Quelques questions.
RH: Pierre, quand as-tu commencé l'élevage d'escargots et qu'est-ce qui t'a amené à cette passion ?
PA: En juin1979, j'étais en vacances en Bretagne (Moëllan sur Mer). Après quelques jours de très beau soleil j’ai
dû décamper à cause de la pluie, direction le Tarn, arrêt en dessous de Limoges pour pique-niquer. Pendant
l'arrêt j'ai remarqué dans un talus un énorme escargot noir d’une grosseur d’un Bourgogne. Après avoir bien
examiné cet animal, nous l’avons emmené en vacances avec nous et enfin jusqu'à la maison, à Louvain-La-
Neuve. Nous l’avons baptisé Nestor. Après avoir examiné cet animal sous toutes les coutures, je l’ai déposé dans
les rocailles du jardin et après 3 jours. plus de Nestor il avait disparu. Au printemps de 1980, mon épouse
l’aperçu dans le persil et 15 jours après il grimpait les marches de la véranda. Par la suite notre Nestor fut
malheureusement piqué par un merle. Etant fasciné par cet animal, c’est depuis 1980 que mes études sur le
comportement et sur l’élevage d’escargots ont démarré.
on _ |
Autre espèce ramenée du Var en France Elles aussi se sentent bien chez Pierre.
Zonites algirus (escargot peson)
RH: Quels sont tes contacts avec l'étranger et avec d'autres hélicicultures?
PA: Mes contacts réels avec l’élevage ont débuté avec les premiers congrès annuels de l'INRA et de GNPE (à
partir de 1981).
NovarEx / Société 8(3), 10 octobre 2007 103
En 1989, suite à ma demande au Ministère de l’Agriculture Fédérale (à l’époque), démarrage d’une étude
relative aux produits hélicicoles, subventionnée par la CEE et exécutée avec ma collaboration par la FUSAG
(terminée en 1992).
En septembre 1995, et sur invitation de l’ANE ( Association italienne de l’héliciculture) à Cherasco, présentation
des élevages belges de petits-gris et de gros-gris
L'association italienne fêtait ses 25 ans d’existence et regroupait 5 associations internationales
En septembre 1999, et sur invitation de l’ANE présentation de l’élevage belge de gros-gris.
Suite aux différentes manifestations hélicicoles en France et en Italie des échanges entre héliciculteurs étrangers
ont été profitables réciproquement.
Un ancien locataire... .Achatina achatina (le géant des géants), a vécu 13 ans et à l'âge de 8 ans a pondu 900
œufs en quinze jours et a perdu 60 gr après la ponte !
RH: Aurais-tu une anecdotes à nous raconter?
PA: Suite à mes recherches sur les individus gros-gris, une sélection s’est imposée et j'ai créé une variété
unicolore "blonde dorée". Cette variété est stabilisée depuis 8 ans. Et les "dorés de Lauzelle" donne 100% de
dorés. Les dorés sont déjà en Cote d’Ivoire, en Italie et à en Asie.
Merci Pierre et à très bientôt !

L'excursion de printemps de la S.B.M.
Parc Naturel de la Burdinale et de la Mehaigne (12 mai 2007)
Claude VILVENS
Le Parc Naturel de la Burdinale et de la Méhaigne (du nom des deux rivières qui le traversent) se trouve
en province de Liège : il regroupe les 4 communes de Braives, Burdinne, Héron et Wanze (ce qui fait 23
villages) et correspond à une surface de 11 000 ha. Considérant qu'il se trouve enchâssé entre la Meuse et surtout
le plateau de la Hesbaye, zone agricole s'il en est, on ne peut qu'être un peu surpris d'apprendre que ces vallées
de la Burdinale et de la Méhaigne abritent en fait une grande diversité de flore et de faune. Il faut dire aussi que
les paysages sont très variés : des versants boisés voisent des étendues agricoles, de beaux affleurements rocheux
voisinent des prairies sèches, on peut même trouver des zones humide voire marécageuses.

106 NOVAPEX / Société 8(3), 10 octobre 2007
De façon surprenante, il est vite apparu qu'il n'existait aucun relevé malacologique précis de cette
région, même après avoir contacté les responsables de la Maison du Parc. La tentation était évidemment trop
forte de prospecter dans une telle zone "vierge" de toute étude. Mais il faut bien dire que les premières
reconnaissances nous ont un peu déçus : non pas pour les milieux en eux-mêmes, mais parce que le nombre de
terrains clôturés est très important. Clairement, on ne va pas où l'on veut, notamment pas sur les beaux rochers
(comme ceux de la Marquise ®) pourtant si alléchants pour un malacologue de terrain. De plus, le mois d'avril
exceptionnellement chaud ne nous aidait guère …
C'est donc un petit miracle que de constater qu'il avait plu la semaine précédant l'excursion ©. Et tous
les espoirs étaient donc permis pour les deux sites que nous avions l'intention de prospecter.
Le Bois Taille-Gueule
Situé près du centre pénitentiaire de Marneffe (quand on vous parlait de grilles ;-) !), ce bois magnifique
s'est révélé très intéressant. Au milieu de fleurs sauvages variées, nous avons trouvé un certain nombre d'espèces
de Terrestres, tant à coquilles que limaces — jamais cependant en très grand nombre :
Clausiliidae Zonitidae
Clausilia bidentata (Strôm, 1765) Aegopinella nitidula (Draparnaud, 1805)

La Traversine à Moha
Après une zone couverte, relativement humide, nous nous sommes orientés vers Moha et la voie de
chemin de fer qui longe puis recoupe la Méhaigne La configuration des lieux pouvait nous faire espérer la
détection d'espèces appréciant la chaleur, comme des Helicella ou Cernuella. En fait, nous avons été accueillis
par des Bradybaena fruticum ! Par la suite, nous avons trouvé beaucoup de coquilles mortes (et souvent
blanchies) mais fort peu de spécimens vivants — un peu décevant donc :
Clausiliidae Hygromiidae
Clausilia bidentata* (Strôm, 1765) Monachinae

Endodonddse Monacha cartusiana* (O.F.Müller, 1774)

Orculidae
Sphyradium doliolum* (Bruguiere, 1792)
Bradybaenidae
Bradybaena fruticum (Müller, 1774)
Le fait d'avoir trouvé des coquilles de Monacha cartusiana (O.F.Müller, 1774), même à l'état mort, mérite
d'être signalé : les références comme Adam donne l'espèce comme rare à l'intérieur de la Belgique tandis que
l'atlas de DeWilde et al. ne la signale pas en Meuse Moyenne (seulement en Haute Meuse). L'espèce est par
contre répandue en France. Cependant, des éléments caractéristiques comme l'ombilic minuscule, partiellement
obturé par le bord du péristome, l'ouverture elliptique avec un épaississement interne la bande jaune suivie d'une
bande rouge tout le long de l'ouverture sont suffisamment discriminants pour que tout risque d'erreur de
———

détermination soit écarté. De nouvelles recherches devraient tenter de savoir si l'espèce est toujours vivante dans
la zone fouillée.
Cette dernière remarque vaut d'ailleurs pour d'autres et il serait sans doute fort intéressant de
reprospecter les deux aires parcourues (Marneffe et Moha), spécialement après une période moins chaude et plus
humide que celle qui fut la nôtre, afin d'affiner notre connaissance malacologique de ces lieux.

L'écho des réunions
Annie LANGLEIT & Etienne MEULEMAN
Réunion du 20 mai 2007 (AL) > Kevin Monsecour : la famille des Columbellidae,
Swainson, 1840.
Kevin Monsecour, spécialiste en la matière, nous a détaillé la
classification récente, très complexe, mais encore en évolution, des
Columbellidae : grande famille, plus de 500 espèces, deux sous-
familles, genres très nombreux.
De ravissantes petites coquilles très mal connues au point que
certaines étaient classées un peu partout, dans d’autres familles, et
qu’inversement, on avait inclus dans les Columbellidae des espèces
non conformes. Leur taille va de 2 à 50 mm, mais se situe plus
souvent aux alentours de 10 mm.
Il nous avait apporté toute une collection d'exemplaires et son
exposé était illustré de photos de chaque genre, un travail
considérable et très intéressant.
Il nous a également signalé les travaux de Madame Marta J. de
Maintenon, une américaine spécialisée en zoologie marine des
Invertébrés, dont les recherches d’ ADN pour cette famille lui sont
très précieuses.
L'assemblée était malheureusement assez clairsemée, sans doute à
cause du beau temps ou des vacances pour certains, mais comme
les absents ont toujours tort, c’est bien connu, ce jour-là ils ont raté
un exposé vraiment passionnant et d’une grande qualité.

Réunion du 23 juin 2007 (EM) + Rolf Aubrichs : La Pourpre. |
Une vingtaine de malacologues sont venus écouter notre charmant orateur. Il s’agissait de Rolf Aubrichs qui
avait fait le déplacement de Suisse pour nous parler de sa passion, la Pourpre. Depuis des années, notre orateur
parcourt le monde pour retracer l’histoire de cette teinture qui influença de multiples peuples au cours de
l'histoire.
Voilà en résumé ce que j'ai pu retenir de sa conférence :
Nous vivons dans le monde, un monde de couleurs. Nous pouvons distinguer différents types de couleurs : les
couleurs naturelles non utilisables par l’homme comme celles de l’arc en ciel ou de la mer, que l’on ne peut
« récolter ». Il y a aussi celles utilisables par l’homme mais qui changent avec le temps (un crabe bleu qui une
fois cuit devient rouge).
Dans le monde végétal, nous trouvons de nombreuses matières végétales, mais beaucoup d’entre elles ne
résistent pas (une tache de fruit sur un vêtement finit pas s’estomper). Il est bon de noter que c’est parfois dans
les plantes les moins colorées que l’on trouve les colorants les plus forts.
Mais venons en à notre sujet : la pourpre.
D'où vient la pourpre ? La légende raconte qu’un chien a croqué dans un coquillage et que sa bouche a été
teintée de rouge. Une princesse passait par là et a voulu un habit de cette couleur. Au Liban, cette légende est
encore bien vivante.
Il faut 12.000 coquilles pour récolter 1,4 g de pourpre (couleurs dérivée de l’indigo). D’un point de vue
chimique, le pourpre est une molécule d’indigo avec deux atomes de brome attachés. C’est une formule
compliquée à reproduire en laboratoire, c’est pour cette raison que la pourpre n’a jamais été fabriquée en grande
quantité.
La couleur pourpre était réservée aux personnages importants, seul l’empereur avait le droit de porter des
vêtements entièrement en pourpre.
Mais comment extrait-on le pourpre ?
Il existe différents procédés pour obtenir la pourpre. La teinture directe, l’animal est frotté contre les fibres et
émet un liquide incolore qui au contact de la lumière teinte le tissu de manière irréversible. Un autre procédé
consiste à extraire la glande avec l’ongle ou avec un pince et de l’appliquer entière ou broyée sur le tissu à
teinter…
Mais la pourpre n’a pas seulement été utilisée au Moyen-Orient. On a retrouvé des traces de son utilisation en
Irlande où les marins utilisaient cette teinture pour marquer leurs initiales sur les vêtement. Au Chili et au Japon,
des morceaux de tissus ont révélé l’usage de cette teinture. En Grèce, des fresques ont été retrouvées avec des
fragments de couleur pourpre.
En résumé, aux quatre coins du monde, les hommes se sont servis de cette couleur naturelle pour teinter leurs
vêtements ou leurs tissus. La pourpre a fasciné et fascine encore les hommes d’aujourd’hui. Il y a de grandes
chances qu’elle ne nous a pas encore révélé tous ses secrets.
La conférence qui nous a été présentée est le résultat d’un travail de recherche personnelle issu d’une passion
personnelle sur la couleur pourpre.
Merci à notre conférencier de nous avoir fait part de sa passion.
(N.D.L.R.) De plus, Rolf nous a offert un exemplaire de "Conchiglie e Archeologia", numéro spécial de la revue
"Preistoria Alpina" dans lequel, entre autres, figure l'un de ses articles sur la pourpre — merci à lui © !

Malheureusement une bien triste nouvelle
Jacques VIDAL
06.12.1926- 22.09.2006
C'est avec beaucoup de tristesse que fin 2006 nous apprenions le décès de M. Jacques Vidal.
Géologue de formation, sa profession devait l'amener dans diverses régions d'Europe et d'Afrique où il devint
rapidement "accroc" aux coquillages grâce à ses recherches fréquentes le long des bords de mer.
Petit à petit il opéra une sélection qui l'intéressait particulièrement et se spécialisa dans les Cardiidae. Il s'est
ainsi forgé une collection de référence qui devait l'amener à étudier cette belle famille de façon très approfondie.
Il devint attaché au Muséum national d'Histoire naturelle de Paris, établissement qu'il fréquentait assidûment
depuis 1984, année de sa retraite. Je l'y ai rencontré à deux reprises, toujours penché sur ses chers Cardiidae.
Il a publié de nombreux articles dans diverses publications, dont Apex et Novapex. Le dernier en date est
malheureusement resté incomplet après son décès, mais Jan Johan ter Poorten, autre spécialiste de cette famille,
a très gentiment accepté de reprendre le manuscrit. Il est publié dans le n° 3 du volume 8 de Novapex.
Une espèce fut également nommée en son honneur: Vepricardium vidali Ter Poorten & Dekker, 2002. Une
marque de respect et un signe de remerciement bien mérité pour le travail de cet homme de valeur que le monde
de la malacologie regrette amèrement.
Au nom du conseil d'administration de la Société Belge de Malacologie nous présentons nos plus sincères
condoléances à son épouse et à sa famille.
Roland Houart
Remerciements.
Je remercie particulièrement Mme G. Vidal, son épouse, et Mme Virginie Héros du MNHN pour les
renseignements qu'elles m'ont aimablement transmis. Merci également à M. Jan Johan ter Poorten pour sa
relecture.

GIOVANNI BUZZURRO
&
PAOLO RUSSO
Les amateurs de mollusques marins de Méditerranée se
réjouiront de la publication de ce très bel ouvrage consacré
au genre Fusinus en Méditerranée. On le doit à la plume de
Giovanni Buzzurro et de Paolo Russo. Ces auteurs ne sont
plus à présenter dans le monde de la malacologie
méditerranéenne. Ils nous offrent ici une monographie
couvrant quatre nouvelles espèces et onze espèces connues.
16 autres taxas sont discutés dans le livre. Les auteurs
abordent entre autres le large éventail du matériel examiné,
les éléments d’étymologie, de chronostratigraphie, et de
systématique; les informations relatives à la description des
coquilles; l’anatomie, l’habitat et la distribution
géographique de chacune des espèces; et enfin différents
points de discussion apportant les éléments de comparaison
appropriés entre espèces voisines. L’iconographie est
abondante: 30 planches (dont vingt en couleur) et 10
tableaux. La protoconque et la radula de chaque espèce
sont également illustrées par des photographies en
microscopie électronique. Les auteurs ont consulté de
nombreuses références et ont eu des contacts avec de
nombreuses personnes afin d’être les plus complets
possible. L'ouvrage écrit en italien et en anglais est préfacé
par le Dr Emilio Rolän (Vigo - Espagne), 1l comporte 280
pages et est publié en tirage limité sur du papier mat (150
g), dos cousu et belle couverture cartonnée en
quadrichromie. L'ouvrage s’achète à 68 € frais de transport
non compris. Un ouvrage qui se doit de figurer en bonne place dans votre bibliothèque.

ANNUARIO MALACOLOGICO EUROPEO

Format: 170 x 240 mm, couverture souple. malacologia@ fastnet.it
Prix: 25 € + frais d'envoi.
Comme les éditions précédentes, ce volume se veut l'annuaire illustré de tous, ou du moins de la plupart des malacologues,
conchyliologues et collectionneurs européens de coquillages.
NovaAPEX / Société 8(3), 10 octobre 2007 ts)
La première partie est consacrée aux musées, classés par pays et alphabétiquement. On peut y trouver une foule de
renseignements: adresse + adresse e-mail et autres données tel que téléphone, fax, horaire des visites, adresse du site, le nom
du conservateur et de ses collaborateurs directs et de nombreuses autres choses bien utiles.
La deuxième partie est dédiée aux sociétés et à leurs publications. Cette
partie est suivie d'adresses de sites malacologiques et de la liste des
différentes bourses européennes (2007 et 2008).
2? 007-2 0 0 . La revue photographique des malacologues et collectionneurs, et
l'annuaire malacologique occupent la majeure partie de cet ouvrage et
clôture ce volume régulièrement mis à jour (la première édition date de
ANNUARIO 1994).
MALACOLOGICO Il est d ailleurs intéressant de noter les nettes améliorations des photos
depuis 1994 (du noir et blanc vers la couleur) et le nombre
EUROPEO d'informations en constante augmentation. De quelques 7 pages de
photos de malacologues et collectionneurs en 1994, la version 2007
EUROPEAN 1 nous en offre à présent 50 pages tout en couleur avec 12 photos par
MALACOLOGICAL INDEX EL
Quelques personnes illustres ont malheureusement disparus du dernier
0. , volume suite à leur décès pour la plupart. Il serait peut-être intéressant
de leur rendre hommage dans un prochain volume en y incorporant leur
photo, ce qui aurait aussi comme résultat de nous remémorer le visage
de certaines personnes trop tôt disparues et quelques bons moments
passés ensemble (ah... nostalgie quand tu nous tiens).
L'index malacologique qui termine ce livre sur 67 pages reprend le nom
et l'adresse postale de la plupart des collectionneurs européens, classés
par pays et par ordre alphabétique.
C'est sans hésitation que je conseille l'achat de ce volume qui nous
permettra de mettre un visage sur le nom d'un personne souvent citée,
qui nous restait malgré tout assez inconnue jusqu'à présent.

Terebridae, A collector guide
par Yves Terryn
pp. 1-57, 65 planches couleurs. Editeur: Conchbooks. Mainzer str. 25, D-555546 Hackenheim,
Format 210 x 300 mm, couverture cartonnée. Allemagne
Prix: 48 € + frais d'envoi. conchbooks @conchbooks.de
Ce livre, comme le souligne le Prof. Philippe Bouchet dans sa
préface, est le résultat d'une discussion qu'il avait eu avec l'auteur
il y a quelques années. Si toutes les discussions pouvaient aboutir
TE REBRIDAE à un tel résultat, le monde de la malacologie s'en trouverait
certainement enrichi.
A COLLECTORS GUIDE L'auteur, comme il le précise dans l'introduction, a voulu nous
présenter un catalogue illustré à l'usage des collectionneurs et des
musées; mais il s'agit également d'une première tentative pour
grouper les espèces de cette très belle famille. Essai réussi dirons-
nous, grâce au listing bien ficelé, regroupé par genre et
quelquefois par groupes d'espèces et aux illustrations. Chaque
espèce est listée, sans mention des synonymes, mais reprenant la
taille, la distribution géographique et quelques commentaires. La
partie systématique se termine par quelques additions à la liste de
Bratcher et Cernohorsky, qui en 1987 avaient publiés une très
bonne révision de cette famille.
Les remerciements d'usage précèdent une bibliographie de
quelques 11 pages, quelques reproduction de Terebra de Sowerby
(1842-1887), l'index, la liste des abréviations et les 65 planches
NaturalArt couleurs.

Les photographies sont d'une qualité irréprochable. Les coquilles sont représentées sur fond noir et sont
accompagnées du nom, de la localité et de la taille. Plusieurs spécimens sont illustrés pour chaque espèce et
quelques 17 planches sont consacrées à la comparaison de la sculpture et d'ouvertures. L'auteur illustre
également quelques photographies d'animaux vivants.
Si vous possédez des Terebridae ou si vous êtes spécialisé dans cette famille, n'hésitez pas, offrez-vous ou faites
vous offrir ce catalogue richement illustré.

la partie systématique proprement dite débute avec le genre
Eudolium qui renferme deux espèces, suivi par le genre Malea
avec également deux espèces et le genre Tonna abritant 29
espèces, distribuées dans 7 complexes différents par l'auteur. La
liste des espèces et de leurs synonymes est donnée pour chaque
sous-famille.
Chaque espèce est présentée de la façon suivante: nom, auteur,
date de description, synonymie, autres références bibliographiques,
localité type, distribution, habitat, dimensions, description,
comparaison et remarques. Le tout est agrémenté d'une photo noir
et blanc de l'espèce et d'une carte illustrant la distribution géographique. De nombreux spécimens provenant du
matériel type sont 1llustrés (holotypes, lectotypes, syntypes..….). Le volume se termine par la bibliographie, en
plus des références déjà données dans le texte, de l'index et des planches couleurs.
Les photographies couleurs sur fond noir agrémentant les 63 planches sont splendides et méritent une mention
spéciale quant à leur qualité. Plusieurs spécimens sont illustrés pour chaque espèce, montrant ainsi la variabilité
de la coquille, avec mention de la localité et de la taille.
Que dire face à une telle étude, si ce n'est que je la conseille vivement à tous ceux que les Tonnidae ne laissent
pas indifférent. Une très bonne acquisition pour toute bibliothèque malacologique.

Ce petit guide des Gastéropodes d'Andalousie est un gros
Caracoles Te rrestres | bijou ! Est en effet ici illustrée et commentée la faune des
Pret e | escargots de cette province d'Espagne et ce l'est avec
ke réussite. Car chaque espèce est tout d'abord décrite sans
détails inutiles, mais avec assez de précision pour qu'une
détermination soit possible — l'introduction de l'ouvrage a
permis de préciser les termes employés (forme de la
coquille, de l'ouverture, sculpture, dentition, etc). Suivent
les dimensions et l'habitat. Enfin, au moyen d'une carte et
G #
y auIa de symboles prédéfinis, le lecteur trouve la distribution,
lidiedann le statut de l'espèce (en danger, vulnérable, de moindre
préoccupation, etc), le fait d'être comestible, consommée
ou pas, etc. Toutes les espèces sont représentées avec au
moins deux vues, souvent trois et bon nombre d'espèces
ont droit à une photo in situ.
Ce remarquable travail a été réalisé avec le concours de l'organisme officiel gérant l'environnement en
Andalousie. Il le mérite bien : on le parcourrait rien que pour son plaisir. Le fait que le texte soit en espagnol
n'est pas trop gênant pour un francophone : avec un dictionnaire, on rassemble vite le vocabulaire nécessaire si 11
le faut vraiment, car les photos parlent le plus souvent d'elles-mêmes !

Une étude approfondie des mollusques du Pliocène Inférieur de Estepona, Espagne. La partie 7 concerne la
famille des Muricidae. Nous vous livrons le résumé de cet important article.
Abstract: In this part of the series giving a systematic account of the Gastropoda of the Pliocene (Zanclean)
deposits of Estepona, province of Mälaga, Spain, the Muricidae are described and discussed. In this part the area
of research has been widened to include material from two other SW Iberian Neogene basins, the Mondego
Basin (western Portugal) and the Guadalquivir Basin (sowthwestern Spain). One new genus is described,
Cathymorula nov gen. and three new taxa introduced, Hexaplex (Trunculariopsis) praeduplex nov. sp.,
Ocenebra sublavata iberopliocenica nov. subsp. and Cathymorula cathyae nov sp. Three of Bellardi’s
homonyms are renamed and lectotypes designated; Purpura tuberculata Bellardi, 1882 is renamed Cathymorula
bellardii nov. nom., P. bicarinata Bellardi, 1882 is renamed C. saccoi nov. nom, and P. elongata Bellardi, 1882
is renamed Purpura elongatobellardii nov. nom. Lectotypes are designated for Murex foliosus, M. gastraldii, M.
trinodosus Bellardi, 1873 and several new subjective synonymies suggested; M. dujardini Tournouër, 1875
junior synonym of M. foliosus Bellardi, 1873; Pollia baccata, P. exacuta and P. affinis Bellardi, 1873 junior
synonyms of Orania fusulus (Brocchi, 1814); Murex gastraldii Bellardi, 1873, M. cyclopterus Millet, 1866
junior synonyms of Purpurellus veranyi (Paulucci, 1866); Favartia incisa auct. European fossil record non
Broderip, 1833 is F. suboblonga (D’Orbigny, 1852). The palaeobiogeography of the Muricidae is discussed, and
the strongly thermophilic character of many of the taxa highlighted. The family suffered dramatically from the
gradual climatic cooling during the Pliocene. Of the 50 species recorded, only eight (16%) survived into the

Il s'agit d'un article imposant et très important pour ceux que les bivalves récents ou fossiles de laissent pas
indifférents. Voici le résumé de cette étude. Pour en savoir plus: http:/www.rsnz.org/publish/jrsnz/2004/007.php
Abstract New Zealand Plio-Pleistocene bivalves revised: Limopsis, oysters, Pecten, Mactra (Maorimactra),
Oxyperas, Lutraria, Austrovenus, Barnea, Myadora. Recent Indo-West Pacific Lutraria species are reviewed;
the Red Sea-East African species L. (Lutraria) turneri Jousseaume resembles L. grandis (Hutton) (adopted in
place of the junior homonym L. solida Hutton). Six new species proposed: Saccella maxwelli (Nukumaruan-
Recent; known previously as S. bellula (A. Adams)); Limopsis turnbulli (Castlecliffian, OIS 15-20, SW
Fiordland); Mactra (Maorimactra) marwicki (late Nukumaruan); M (Maorimactra) carteri (early Castlecliffian,
OIS 45?-19); Paphies delta (early Castlecliffian, OIS 31 ?-17); Myadora fortecosta (Kapitean-Opoitian).
Further Indo-West Pacific warm-water migrants to New Zealand: Chama ruderalis Lamarck (Kapitean-
Nukumaruan; = C. huttoni Hector, = C. pittensis Marwick); Lutraria (Psammophila) vellai (Beu) (late
Nukumaruan); probably the two New Zealand late Neogene Ctenoides species. Further temperate migrant from
the Atlantic: Lutraria (Lutraria) grandis. New synonymy: Xenostrobus Wilson = Limnoperna Rochebrune;
Pecten novaezelandiae (Reeve) = all other New Zealand Pecten names; Serratina eugonia (Suter) =S.
charlottae (E. A. Smith); Oxyperas komakoensis (Carter) = O. elongata (Quoy & Gaimard); Austrovenus
stutchburyi (Wood) varies clinally over New Zealand, = À. aucklandica Powell, = À. crassitesta Finlay;
Dosinia (Austrodosinia) horrida Marwick = D. anus (Philippi) (Nukumaruan-Recent); Panopea wanganuica
Powell = P. smithae Powell (Nukumaruan-Recent); Myadora stephaniae Carter = M waitotarana Powell
(Waipipian-Nukumaruan). Distinctive bivalves extinct at the end of Nukumaruan time: Glycymeris shrimptoni
Marwick, Patro undatus (Hutton), Lutraria (Lutraria) grandis, L. (Psammophila) vellai, Paphies crassiformis
(Marshall & Murdoch), Eumarcia plana Marwick, Dosinia (Raina) nukumaruensis Marwick, Myadora
waitotarana. Ennucula Xredale is used for Cenozoic and Recent Nuculominae; the application of Leionucula
Quenstedt is unclear. Saccostrea glomerata (Gould) is used in place of S. circumsuta (Gould). Protothaca
crassicosta (Deshayes) (formerly Haweran-Recent) is recorded from Opoitian rocks. Pecten novaezelandiae
appeared below Potaka Tephra (1.0 Ma) during OIS 29 or earlier in eastem New Zealand, but just above the
Brunhes-Matuyama transition (0.78 Ma, early OIS 19) in Wanganui Basin. Oxyperas elongata and Barnea
similis (Gray) changed anagenetically through late Miocene-Pleistocene time; earlier forms are conspecific with
Recent ones. Tawera Marwick is restored as a genus. Purpurocardia Maxwell is compared with Glans Megerle
von Muhifeld and Glyptoactis Stewart, and ail are retained. Limnoperna huttoni (Suter) became extinct during
OIS 13, Barytellina crassidens Marwick during OIS 9 or younger. Pholadidea tridens (Gray) (OIS 23 & 5a) and
Ostreola virescens (Angas, 1868) are recorded fossil

Morceaux choisis
Claude VILVENS
Le moins que l'on puisse dire, c'est que le magazine scientifique La Recherche y a mis un coup
concernant les grandes questions portant sur le Vie. Jugez-en plutôt …
1. Les Dossiers de la Recherche n°27 (mai-juillet 2007). L'évolution —- Comment les
espèces s'adaptent.
Le sommaire ci-dessous peut en convaincre : ce numéro brosse un panorama complet des différentes concepts
qui soutiennent le mécanisme de l'évolution (le sous-titre du sommaire est d'ailleurs : "Les moteurs de
l'évolution"). Soulignons notamment "L'arbre des penseurs" (pp.10-11) qui reprend les grands noms des
théoriciens de l'évolution (comme Haeckel, Mayr ou Gould) avec un résumé de leur point de vue, "La sélection
naturelle" (pp.12-15) qui explique comment la Phalène du Bouleau (un papillon) peut à la fois argumenter en
faveur des théories évolutionnistes et créationnistes, un magnifique portfolio "L'œil s'est-il construit pas à pas ?"
(pp.34-39) avec de splendides photos (ici, une Coquille St Jacques et un Nautile) et les nouvelles idées au sein
du darwinisme exposées dans "Le darwinisme évolue aussi" (pp.40-45).

2. Les Dossiers de la Recherche n°28 (août-octobre 2007). Biodiversité — Les menaces sur
le vivant.
Voici bien sûr un sujet fort "à la mode". Mais comme tout cela est passionnant : le sommaire peut nous
convaincre que la plupart des facettes du sujet sont abordées par des spécialistes compétents. De notre point de
vue de malacologues collaborant avec le MNHN de Paris, on ne peut pas ne pas signaler
+ "Le monde marin" par F. Lemarchand avec Ph. Bouchet et B. Fontaine (pp.26-28) — sans doute ne faut-il pas
vous présenter Philippe Bouchet, professeur au MNHN : ici se trouvent les réponses succinctes à 7 questions
portant sur la biodiversité marine, comme par exemple "En quoi la biodiversité marine se distingue-t-elle de sa
cousine terrestre ?" ou "Les effets du réchauffement climatique sont-ils déjà perceptibles ?";
+ "Faune mystérieuse des profondeurs" par P. Cayré et B. Richer de Forges (pp.38-41) — ce dernier est un
représentant bien connu de l'IRD (l'ex ORSTOM) en Nouvelle Calédonie : sont ici présentées des espèces bien
peu connues, comme par exemple un isopode (Crustacé) de 40 cm de long, alors que les espèces de ce groupe ne
dépassent jamais quelques mm !
+ ‘"L'insaisissable inventaire des espèces" par Ph; Bouchet (pp. 48-55) : on va retrouver ici les thèmes que
l'auteur avait développés lors de sa conférence donnée au cours du 40°" anniversaire de la SBM en 2006, soit
donc la description des nouvelles espèces et leur publication (avec la problématique du "handicap taxonomique",
ce goulet d'étranglement résultant du fait que les moyens humains sont bien trop faibles pour tout inventorier
dans un délai raisonnable), le nombre d'espèces existant et les nouvelles perspectives apportées par des biotopes
comme les sources chaudes ou le monde souterrain. A signaler aussi la "Fauna Europea", programme visant à
constituer une base de données contenant toutes les espèces terrestres et d'eau douce d'Europe (de l'ordre de
140 000), avec son Top 10 des espèces nouvelles récentes illustrées dans l'article (voir
http://www.faunaeur.org/).

Le dictionnaire de malacologie
le: La SBM entend donner ici, à moyen terme, un outil qui permettra à tous de trouver, en français, la définition d'un
terme de malacologe ou quelques précisions sur un malacologue célèbre. Cette partie de notre site sera probablement toujours
en cours d'évolution Mais ne sera-ce pas là aussi son intérêt ?
Ce "dctionnare de malacologie” sera un travail collectif et de longue haleine. Il ne faut donc pas s'étonner de ne pas
trouver pour l'instant tous les termes ou tous les malacologues ! Notre dictionnaire s'articule selon deux axes :
+ La défimhion des termes de malacelome
+ Les malacologues célèbres
e Les grandes expéditions maritimes

INTRODUCTION
Numerous species belong to the genus Calliotropis :
about 50 valid species live in the only Indo-Pacific
area. Most of these species live at rather great depth
(few hundred meters), some species even living in
greater depth (over 1000 m). So, it is understandable
that some new species have been discovered only
recently during new deep water dredging campaigns
(Rehder et Ladd, 1973; Marshall, 1979; Lan, 1990;
Jansen, 1994; Lee & Wu, 2001; Vilvens, 2004, 2005,
2006; Poppe et al., 2006). In the same way, the
distribution area of well-known species, primitively
rather restricted, has been extended to other areas,
sometimes far away from the original locality.
For the last twenty years, numerous French
expeditions conducted by the IRD (Institut de
Recherche pour le Développement, Paris - ex-
ORSTOM) and the MNHN (Muséum national
d'Histoire naturelle, Paris) have taken place in a large
Indo-Pacific area, from Taiwan, Indonesia and
Philippines to Solomon Islands, New Caledonia, Fiji,
Vanuatu and even far away up to Tonga and
Marquesas Islands. They have brought a huge deep
water material of highly scientific interest, among
others various trochids, especially Calliotropis
species. Some new species have already been
described from this material (Vilvens, 2004, 2005,
2006; Poppe et al., 2006). The present paper propose a
synthetic report on most of the species of Calliotropis
collected during these French expeditions, describing
30 new species (and 1 new susbspecies) and extending
the distribution area of 25 known species. The
variability of some of these species is discussed here.
A list of the Recent Calliotropis species of the Indo-
Pacific area, with their respective distribution, 1s also
provided as appendix at the end of this paper.
Material and methods. The material studied in this
paper was brought by French IRD-MNHN expeditions
in a large Indo-Pacific area, covering mainly Taiwan,
Indonesia, Solomon Islands, New Caledonia, Fiji,
Vanuatu, Tonga and Marquesas Islands. The
following table lists these campaigns :

New records and new species of Calliotropis from Indo-Pacific
Regarding the distribution of the new species and the
extension of the distribution of known species, the
range is taken from the internal intervals of the two
extremes values
\s for the description methodology, the main
conchological features used are (see sch. 1 below) :
+ general shape of the shell (depressed, high spired
- cyrtoconoidal, conical, coeloconoiïdal);
pa 7” _ :
-
Lee ee
RAR EET ET
peripheral cord
+ shape of the whorls (convex, concave, straight -
with or without shoulder or keel);
+ spiral cords of the whorls (ontogeny, number,
beads, distance between);
+ spiral cords on the base (number, beads, distance
between);
+ spiral cords within the umbilicus (number);
+ shape of the aperture, the outer and inner lip.

Schema 1 : Useful features of Calliotropis shells; H : heï
P3,.. : primary cords: SI, S2, S3, … : secondary cords.
Considering the relatively poor anatomical
information about Calliotropis species, no subgenus
has been described on such considerations. So by now
only conchological features was used to define
subgenera. In original descriptions we can only find
the subgenera So/aricida Dall, 1919 (characterized by
a depressed spire and a broad umbilicus - although the
type species Solariella (Solaricida) hondoensis Dall,
1919 has precisely a not so wide umbilicus) and
Adamsenida Habe, 1952 (with ÆEnida gemmulosa
A.Adams, 1860 as type species - this subgenus is
vaguely characterized by strong spiral cords on
whorls, a convex base and a wide umbilicus). Poppe et
al. (2006) described 2 new
Schepmanotropis (type species
4
subgeneràa :
Solariellopsis
ght; W : width; HA : height of the aperture; P1, P2,
calcarata Schepman, 1908) and Spinicalliotropis
(type species : C. spinosa Poppe, Tagaro & Dekker,
2006). This survey neither defines new subgenera nor
uses existent ones because the range of variations of
Calliotropis shells seems too wide to allow the use of
only conchological features without anatomical
(especially radula) considerations.
Species are here listed following on an order based
upon the height (H) and the height/width ratio (H/W)
of the shell (using the mean of these values computed
for available specimens). So eight formal groups can
be distinguished : large (H>=15 mm), rather small
6<—=H<15 mm) and small shells (H<6 mm) with an
elevated spire (H/W>=1), large and rather small shells
with a rather elevated spire (0.7<ratio<l), and rather
C. VILVENS
small and small shells with a rather depressed spire
(ratio<—0.7). Within each group, the known species
are listed before the related new species, so that the
NOVAPEX 8 (HS 5): 1-72, 10 juin 2007
easier to understand. Such an order may look
arbitrary, but if helps to locate the different species
through the paper. More precisely :

Diagnosis. À Calliotropis species with high spire,
conical shape, whitish, with 2 spiral cords on spire
whorls, the granules of the abapical cord the strongest:;
2 peripheral granular cords and a very weak subsutural
third granular cord on last whorl; 4 granular spiral
cords on base: no umbilicus.
Description. Shell tall for the genus (height up to 31.5
mm, width up to 25.2 mm), higher than wide, rather
thin, conical; spire high, height 1.2x to 1.3x width,
3.2x to 3.5x aperture height; without umbilicus.
Protoconch about 400 um, of about 1 whorl, smooth,
bulbous, with a weak, poorly visible, terminal varix.
Teleoconch up to 9.6 slightly convex whorls, bearing
3 spiral granular cords and prosocline threads: nodules
from cords produced by intersections with axial
threads on 5 first whorls.
Suture visible, not canaliculated.
First whorl convex, sculptured by about 20 weakly
prosocline smooth ribs, interspace between ribs 2x
broader than ribs: primary spiral cord P3 appearing
almost immediately, Pl appearing about half a whorl
later, weaker than P3, both bearing rounded nodules:
P2 absent. On next three whorls, PI and P3 stronger,
Pl still weaker than P3: nodules of P3 sharp:
interspace between axial ribs becoming 3x broader
than ribs. On fifth whorl, P4 weakly emerging from
suture, with nodules smaller and more numerous than
nodules of PI and P3: axial ribs becoming weaker. On
sixth whorl, Pl becoming weaker, with blunt nodules;
axial ribs obsolete. On seventh whorl, PI becoming
obsolete, only poorly visible; nodules of P3 large,
prickly, isolated. On last whorl, PI very weak, almost
disappearing on some specimens: P3 the strongest: P4
fully visible, peripheral, with small sharp nodules four
times more numerous than nodules of P3.
Aperture subelliptic, weakly flaring on the largest
specimens; outer lip rather thin, indented by external
spiral cords, producing an angle with inner lip, this
angle obtuse on the largest specimens.
Columella slightly curved, slightly prosocline, without
tooth.
Base moderately convex, with 4 granular spiral cords:
innermost one stronger than others, with strong
nodules, bordering umbilical area; distance between
cords 3x broader than cords; numerous thin, weak,
crowded axial lamellate threads between cords.
Colour of teleoconch hazel beige, without maculation:
protoconch whitish.

Table 3. - Calliotropis conoeides : Shells measurements in mm for types and bigger specimen.
Discussion. Calliotropis conoeides n. sp. is close to C.
pagodiformis (Schepman, 1908) (Figs 1-5) from
Indonesia and Solomon Islands, but this species has a
less slender shape, a much more channelled suture, the
sharp nodules of PI clearly visible and adapically
oriented on the last whorls.
Regarding the spiral cords on whorls and base, the
new species remembers also C. minorusaitoi Poppe,
Tagaro & Dekker, 2006 from Philippines, but this
species is similar in size for less numerous whorls, has
a globose, not conical, shape and a wide umbilicus.
C. conoeides n. sp. 1s close to C. philippei Poppe,
Tagaro & Dekker, 2006 from Philippines, but this
species has an area between PI and P2 with a convex
shape, giving a cyrtoconoidal, not conical, shape to
the shell, has a much weaker PI cord, more numerous
and more closely packed spiral cords on the base and
seems (regarding the plate of the original description)
to have an open wide umbilicus.
Etymology. Conical (Greek: Kovoeônc) - with
reference to the general shape of the shell.

Discussion.
Calliotropis helix n. sp. is close to C. pagodiformis
(Schepman, 1908) (Figs 1-5) from Indonesia and
Solomon Islands, but this species has a more slender
shape, a more channelled suture, the sharper nodules
of PI adapically oriented on all the whorls and
narrower umbilicus partially open.
The new species may also be compared to C.
conoeides n. sp. (Figs 6-9) from Solomon Islands, but
this species is more slender (ratio H/W of 1.2 to 1.3
instead of 1.0 to 1.1) and has the nodules of P1 still
clearly visible on the last whorls, the 3 outermost
spiral of cords distinctly granular and no umbilicus.

Discussion. Calliotropis cynee n. sp. 1s rather close to
C. conoeides n. sp. (Figs 6-9) from Solomon Islands,
but this species has a more slender shape, a granular
P4 emerging much earlier (at the fourth whorl), four
spiral cords on the base and no umbilicus.
The new species also weakly resembles to the
cosmopolite C. infundibulum (Watson, 1879) (Figs
84-85), but this species shows a PI cord strong and
granular, still present on last whorl, and has 4 ou 5
spiral cords on the base.
C. cynee n. sp. is also superficially similar to C.
diomediae (Verril, 1880) from north-western Atlantic,
but this slightly larger species has a strong, granular
spiral cord P1, far from the suture on last whorl, and 4
spiral cords on the base.
The new species remembers also C. minorusaitoi
Poppe, Tagaro & Dekker, 2006 from Philippines, but
this species is larger for a smaller number of whorls,
has a globose, not conical, shape,
umbilicus and 4 spiral cords on the base.

more widespread. In some examined specimens, PI is
dividing in two cords, but except this feature, all
specimens share the same ontogeny of cords as stated
in the original description.

Distribution. South-western Pacific (from Solomon
Islands to New Caledonia and Fiji), 707-1360 m.
Diagnosis. À Calliotropis species with high spire,
conical shape, silvery, with 3 spiny primary spiral
cords on spire whorls and up to 7 spiral spiny cords on
last whorl; base with about 7 spiral spiny cords:
umbilicus with 2 spiny spiral cords inside.
Description. Shell of small size for the genus (height
up to 6.5 mm, width up to 4.9 mm), higher than wide,
thin, conical; spire high, height 1.1x to 1.3x width,
2.7x to 4.3x aperture height; umbilicus deep and rather
large.
Protoconch from 250 to 300 um, of 1 whorl, smooth,
bulbous, with a rather thick, slightly curved terminal
varix.
Teleoconch up to 6.2 convex whorls, bearing up to 7
spiral granular cords and prosocline ribs;
nodules from cords produced by intersections with
axial ribs.
Suture visible, impressed but not canaliculated.
First whorl convex, sculptured by about 15 weakly
prosocline smooth thick ribs, interspace between ribs
2x broader than ribs. Primary spiral cords PI
appearing at end of first whorl or at beginning of
second whorl; P2 appearing a quarter of whorl later;
both cords formed by weak rounded nodules. On third
whorl, P2 stronger than PI, with nodules becoming
sharp and clearly separated; P3 appearing at mid
whorl, quickly as strong as P2. On fourth whorl, P2
and P3 strongly spiny; PI slightly weaker than the
other cords; spines of PI and P2 oriented at an angle
of about 45°, those of P3 horizontally oriented. On
fifth whorl, spines of cords becoming scaly; PI
dividing into two cords, the most adapical weaker;
axial ribs still strong, becoming more prosocline; SI
and S2 appearing at end of whorl or on the sixth
whorl. On last whorls, P4 emerging from suture,
weaker than P3, spiny; S3 appearing near begin of
sixth whorl, becoming spiny on some big specimens.
Aperture circular; outer lip thin, without angle with
inner lip.
Columella curved, vertical, without tooth.
Base moderately convex, with 4 main spiny spiral
cords and a weaker cord between them; outermost the
thickest, innermost the thinnest with sharp thin spines,
bordering umbilicus; distance between cords similar in
size to cords; axial ribs clearly visible, connecting
nodules of spiral cords.
Umbilicus rather wide, diameter measuring ca. 25% of
shell width, deep, funnel shaped, with thin ribs and 2
spiny spiral cords, sometimes with an additional thin
spiral cord near border.
Colour of teleoconch light pinkish brown; protoconch
off-white.

Table 6. - Calliotropis chalkeie : Shells measurements in mm for largest types.
Discussion. This species is rather variable regarding
the shape of the spines of the spiral cords.
Calliotropis chalkeie n. sp. is very close to C. spinosa
Poppe, Tagaro & Dekker, 2006 from Philippines, but
this species is slightly less elevated, is smaller for a
14
similar number of whorls and its last whorl is higher
than half of the shell height (instead of mesuring about
2/5 of this height).
C. chalkeie n. sp. is rather close to C. lamellifera
Jansen, 1994 (Figs 20-23) from eastern Australia, but
C. VILVENS
this species has a more acute shape, thicker, not scaly,
less numerous spines on the spiral cords on the
whorls, thinner, nearly smooth outermost spiral cords
on base without strong axial ribs between them, and
nodular, not spiny, spiral cords in the umbilicus.
The new species also superficially similar to C.
hondoensis (Dall, 1919) from Japan, but this much
taller species has granular, not spiny, thinner cords on
whorl, and nearly smooth outermost spiral cords on
base without strong axial ribs between them; its
umbilicus is wider than the one of the new species.
C. chalkeie n. sp. also weakly resembles to C.
solariellaformis Vilvens, 2006 (Figs 32-33) from
Réunion Island, but this species is different in having
a slightly less elevated spire, SI appearing much
earlier, less numerous and not spiny granules on spiral
cords and a proportionally larger aperture.
The new species may also be compared to C. ericius
Vilvens, 2006 (Figs 34-35) from Mayotte and Réunion
Islands, but this species has more convex whorls, a
less elevated spire, no S2, less numerous and only
prickly, not scaly, spiny granules on spiral cords.
Remarks. All the specimens of Solomon Islands have
a SI cord always appearing first, at end of fourth
whorl and S2 appearing second at end of fifth whorl.
However, this inversion of order of apparition of S1
and S2 compared to the most specimens of New
Caledonia may also be found in some specimens of
Wallis Is., Futuna Is., Loyalty Basin and Fiji. So this
feature can't be used to distinguish a geographical
subspecies.
Etymology. Thistle (Greek : yaAkeun), used as a noun
in apposition - with reference to the spiny nodules of
the spiral cords.

Remarks. The main distinguishing features of C.
crystalophora Marshall, 1979 are a small size (height
about 4.5 mm), a relatively high spire, up to 7.5
whorls, 2 sharp spiral cords on whorls (P1 near the
suture, separated from it by a nearly horizontal
subsutural ramp, and P3 stronger, median), P4
peripheral on last whorl, widely spaced axial ribs on
the whole surface, microsculpture of irregular crystals,
4 granular spiral cords on the base, a shallow, rather
narrow umbilicus.
There is no mention in the original description of
spiral cords within the umbilicus, but close
examination of the NMNZ holotype showed presence
of at least one thin spiral cord. I don't know any other
reference to this species and there is no indication
about the variability of the shell. Specimens of

New records and new species of Calliotropis from Indo-Pacific
First whorl convex, sculptured by about 15 prosocline
smooth ribs, interspace between ribs 1.5x broader than
nibs. Primary spiral cords PI appearing at end of first
whorl, P3 at beginning of second whorl, both granular:;
P2 absent. On second whorl, P3 slightly stronger than
PI; PI producing a weak shoulder and P3 a weak keel.
On third whorl, beads of PI slightly sharp, blunt,
adapically oriented; axial ribs thicker, more
prosocline, distance between them as broad as ribs. S1
appearing on fifth whorl, weak; S3 appearing at end of
fifth whorl or at begin of sixth whorl, weaker than P3
but quickly stronger than SI; tertiary cords TI and T3
may appear between P1 and SI, and SI and P3; axial
ribs more prosocline in area above P3 than under this
cord. On last whorl, P4 emerging from suture, almost
as strong as P3.
Aperture circular, indented by external spiral cords;
outer lip thin, without angle with inner lip.
Columella more or less straight, slightly oblique,
without tooth.
Base moderately convex, with 4 thick granular spiral
cords; distance between cords similar in size to cords;
strong axial ribs between cords, connecting beads of
spiral cords.
Umbilicus rather narrow, diameter measuring ca. 10%
of shell width, rather deep, funnel shaped, with thin
ribs and 1 weak spiral cord inside, near border.
Colour of teleoconch ivory white; protoconch
translucid white.

Discussion. Calliotropis ptykte n. sp. is close to C.
crystalophora Marshall, 1979 from New Caledonia
area, but this species has a larger H/W ratio, beads of
spiral cords thicker and more spaced, axial ribs more
spaced out, no SI, outermost basal spiral cords nearly
smooth.
Regarding the number of primary spiral and basal
cords, the new species may also be compared to C.
chuni (von Martens, 1904) from eastern Africa, but
this species has thicker, sharp and more spaced beads
on spiral cords, lacks SI and S3, has outermost
smooth basal spiral cords and no spiral cord within the
umbilicus.
Etymology. Pleated (Greek : rTuytoc) - with reference
to the crowded axial ribs on the surface of the shell.

Distribution. Indonesia, 522 m (Schepman, 1908):
New Caledonia, 282-305 m.
Remarks. The examination of the holotype shows that
the main distinguishing features of Calliotropis
multisquamosa (Schepman, 1908) are a small size
(height about 5.5 mm), a moderately elevated spire,
teleoconch up to 5 whorls, 3 sharp spiral cords on
whorls (P2 and P3 the strongest, PI appearing later,
weaker), an additional P4 peripheral on last whorl, 3
granular spiral cords on the base and a shallow, wide
umbilicus with 1 spiral cord inside.
The New Caledonian specimens map these features,
except a slightly more elevated spire and the fact that
Pl is lacking in subadult and juvenile specimens. So,
despite the huge gap between New Caledonia and the
type locality, there is no reason to not use this
available name.

Discussion. Calliotropis solomonensis n. sp. differs
from C. multisquamosa (Schepman, 1908) (Figs 50-
53) by the conspicuous shoulder at P2 and the more
vertical walls of the umbilicus. Both are close to C.
muricata (Schepman, 1908) (Figs 70-71) from
Indonesia, but this species has a more depressed spire,
two columellar denticles and two (instead of only one)
spiral cords within the umbilicus.
Etymology. After type locality and known
distribution restricted to Solomon Islands area.

up to 4.8 mm, width up to 4.7 mm), almost as broad as
high, rather thin, conical or slightly cyrtoconoidal:
spire moderately high, height 0.9x to 1.1x width, 3.4x
to 4.6x aperture height; umbilicus rather narrow.
Protoconch from 150 to 180 um, of 1 whorl, more or
less glassy, with a very weak terminal varix.
Teleoconch up to 6 weakly convex whorls, bearing up

horizontal ramp and P3 producing a strong keel. At
end of fourth or at begin of fifth whorl, P1 dividing
into two cords, the abapical one stronger; beads of P3
becoming weakly scaly; SI appearing at end of fifth
whorl or at begin of sixth, weak, granular. On last
whorl, P4 emerging from suture, slightly weaker than

Table 9. - Calliotropis echidnoides : Shells measurements in mm for types.
Discussion. Calliotropis echidnoides n. sp. is close to
C. echidna Jansen, 1994 (Figs 68-69) from eastern
Australia, but this slightly taller species has a spire
with first part coeloconoïidal and second part
cyrtoconoidal, no SI, all beads of spiral cords strongly
spiny and a notch under the basal columellar tooth.
The two species occupies adjacent areas whose
southern New Caledonia area is the border line.
The new species may also be compared to C. muricata
(Schepman, 1908) (Figs 70-71) from Indonesia, but
this species has a more depressed spire, different
ontogeny of spiral cords of whorls and two columellar
denticles (instead of a single basal tooth).
C. echidnoides n. sp. also weakly remembers C.
malapascuensis Poppe, Tagaro & Dekker, 2006,
described from a single specimen from Philippines,
but this similar in size species has only 3 spiral cords,
the nodules of P1 and P2 being much bigger than on
the cords of the new species, and only one spiral cord
inside the umbilicus.
Etymology. After the close species C. echidna Jansen,
1994.

weak differences between specimens from Philippines
and those from Solomon Is. are that the latter have a
less elevated spire, slightly stronger beads on PI and
P2, and a reddish brown colour (not light brown).
Almost all of the specimens from Solomon Is. have 3
spiral cords on the base, but we found also at least one

New records and new species of Calliotropis from Indo-Pacific
Distribution. Midway Islands, 600 m and Taiwan,
876-904 m.
Remarks. This species was originally described from
the central Pacific as a Calliostomatidae, but clearly
belongs to the genus Calliotropis. Following the
original description (types were not available), the
main distinguishing features of Calliotropis
midwayensis (Lan, 1990) are a relatively large size
(height about 21 mm), a moderately elevated spire, a
teleoconch up to 7 whorls with one subsutural and one
peripheral spiral cords, both granular, thick axial ribs,
about 7 thin spiral cords on the base and a deep and
wide umbilicus without spiral cord inside.
Although there is a huge gap between the area where
the Taiwanese material is coming from and the type
locality (can one imagine that the types shells were
brought by the Taiwanese boat of which dredging
revealed the species ?), in absence of soft parts, I see
no reason to discriminate the examined specimens
from C. midwayensis.
Some precisions can be given for the examined shells.
Regarding the spiral cords on the whorls, PI and P3
appear at end of first whorl and they become obsolete
after the third whorl, P3 disappearing and PI at most
visible as a weak, low cord; P4 appears at third whorl,
granular, with widely spaced, small, prickly granules;
P2 is absent. Another feature that not appears in the
original description is that some specimens develop a
columellar callus covering partially or totally the
umbilicus (Figs 92-95).

Distribution. Solomon Islands, alive in 387-749 m.
Diagnosis. À rather big Calliotropis species with a
moderately elevated, more or less conical spire, nut-
brown, with 3 granular spiral cords on whorls; cords
rather similar in strength but with a number of beads
on last whorls decreasing from adapical to abapical
cord; beads of the two abapical cords scaly; base with
4 or 5 granular spiral cords; large umbilicus without
spiral cord inside.
Description. Shell of rather large for the genus (height
up to 23.8 mm, width up to 27.4 mm), broader than
high, rather thick, conical to weakly cyrtoconoidal;
spire moderately elevated, height 0.8x to 0.9x width,
2.6x to 3.4x aperture height; broad umbilicus.
Protoconch of about 300 um, of 1 whorl, dome-
shaped, without terminal varix, always damaged in
large specimens.
Teleoconch up to 7.9 weakly flat to slightly convex
whorls, bearing 3 spiral granular cords; nodules from
cords produced by intersections with axial ribs that are
quickly obsolete after first whorls; secondary thin
axial ribs on abapical part of next whorls.
Suture impressed, not canaliculated.
First whorl convex, sculptured by 15 orthocline
smooth ribs, interspace between ribs from 2.5x to 3x
broader than ribs; primary spiral cords PI and P3
appearing almost immediately, granular; P1 weaker
than P3. On second whorl, P1 and P3 thicker, similar
in size; interspace between prosocline ribs 2.5x
broader than ribs. On third whorl, P3 slightly stronger
than PI, with granules slightly sharp; P4 emerging
from suture, granular, similar in strength to P3; P2
absent. On fourth whorl, beads of P3 strongly sharp,
oriented at 45°; beads of P4 sharp, 2x more numerous
than beads of P3; P1 much weaker than P3 and P4;
axial ribs obsolete. On fifth and following whorls,
beads of P3 and P4 scaly; beads of P4 much closer to
each other; secondary thin axial ribs in subsutural area
and between P3 and P4; beads of PI becoming more
visible, large, isolated, not scaly. On last whorl, P4
peripheral; area between P3 and P4 slightly concave.
Aperture subelliptic; outer lip slightly flaring, meeting
inner lip with an obtuse, poorly marked angle.
Columella curved at first third, oblique, reflected into
umbilicus, without basal tooth.

New records and new species of Calliotropis from Indo-Pacific
Base moderately convex, with 4 or 5 granular spiral
cords, innermost cord stronger and bordering
umbilicus; distance between cords more or less similar
in size to cords; very thin, crowded axial ribs between
cords, not connecting beads of spiral cords (about five
in number for one bead).
Umbilicus broad, diameter ca. 30% of shell width,
deep, funnel shaped, with thin axial ribs only at rim
and without spiral cord inside.
Colour of teleoconch and protoconch nut-brown.

Table 10. - Calliotropis asphales : Shells measurements in mm for types.
Discussion. The combination of a large size, a solid
shell with a conical spire, a missing P2 with scaly P3
and P4 makes Calliotropis asphales n. sp. hard to
confuse with another Calliotropis species.
Reagarding the conical shape and the number of spiral
cords, the new species can be compared to C.
micraulax Vilvens, 2004 (Figs 72-73) from New
Caledonia and Vanuatu, but this similar in size species
has spiral cords with much thinner, more regular,
never scaly beads, thin axial prosocline threads on the
whole surface and much thinner spiral cords on the
base with wider interspace between them.
Considering the same criteria, C. asphales n. sp. also
remembers C. granolirata (Sowerby, 1903) (Figs 100-
101) from South Africa, but this slightly smaller
species lacks an umbilicus, has a more elevated spire,
two abapical spiral cords with prosocline elongated
beads and basal spiral cords with axially elongated
beads.
Etymology. Strong (Greek: aopaanc) - with
reference to the stocky shape of the shell.

New records and new species of Calliotropis from Indo-Pacific
C. VILVENS
Discussion. The new species has obvious
differences regarding allied species whose
characteristics are constant. That is, Calliotropis
pistis is close to C. blacki Marshall, 1979 (Figs
198-201) from Kermadec Islands and New
Caledonia, but this slightly bigger species lacks the
spiral cord SI and has only 4 spiral cords on the
base. Also, C. pistis is close to C. abyssicola
Rehder & Ladd, 1973 from central Pacific, but this
species (of which all specimens described lacks
protoconch and first whorl) is more depressed and
has only up to 4 spiral cords on the last whorl.
The new species may remember C. keras n. sp.
(Figs 212-213) from Fiji and Tonga, but this
species is much more depressed, always lacks the
spiral cord SI, has only 5 spiral cords on the base
and a spiral cord inside the umbulicus.
The new species may also be compared to C.
derbiosa Vilvens, 2004 (Figs 74-75) from Vanuatu
and Fiji, but this species has a conical or slightly
coeloconoiïdal shape, only 4 spiral cords on the
whorls and only 6 spiral cords on the base.
Etymology. Loyalty (Greek : motic), used as a
noun in apposition - with homonymous reference to
type locality of the new species.

Protoconch of about 400 um, of 1 whorl, without
terminal varix.
Teleoconch up to 6.4 convex whorls, bearing up to
3 spiral granular cords different in size; nodules
from cords produced by intersections with axial
ribs; axial sculpture on first whorls, reduced to thin,
crowded, scaly ribs on last whorls.
Suture visible, impressed, not canaliculated.

after mid of whorl, granular, much weaker than P1
and P3; P2 absent; axial ribs becoming weaker,
interspace between ribs 2.5x broader than ribs. On
fourth whorl, PI becoming obsolete, P3 with strong
nodules well spaced: beads of P4 twice more
numerous than beads of P3; axial sculpture
disappearing except between P3 and P4. On fifth
whorl, beads of P3 and P4 scaly; beads of P4 three

Table 12. - Calliotropis dicrous : Shells measurements in mm for types.
Discussion. The combination of a coeloconoidal
shape, a spiral cord P2 absent, crowded thin axial
threads and two abapical cords very different in size
and shape for Calliotropis dicrous n. sp. makes it hard
to confuse with another Calliotropis species. The only
one rather close to the new species is C. boucheti
Poppe, Tagaro & Dekker, 2006 (Figs 208-209) from
Philippines, but this similar in size species has a
conical shape, a subangulate periphery, an aperture
with a rounded outer lip, an existing spiral cord P2
and the two abapical spiral cords of the whorls evenly
spaced, similar in size, with similar knobs.
Etymology. Biconical, with two tips (Greek : äkpooc)
- with reference peculiar shape of the shell that
remembers a biconical potery.

Distribution. South China Sea, 400-500 m (Lee &

Caledonia, 620-713 m.
Remarks. This species (for which request to borrow
types never succeeded) was originally described from
South China Sea, with as main distinguishing features
(considering mainly pictures of the original
description) 3 spiral cords on the whorls (P3 the most
prominent, P2 absent) and about 6 spiral cords on the
base, the cord around umbilicus stronger. The two
New Caledonian specimens are significantly smaller
for the same number of whorls, have lower, weaker
spiral cords on the base and the walls of umbilicus
steeper. Although there is a huge gap between locality
type and the two area here recorded, it is hard to
discriminate the examined specimens from C.
scalaris. Only additional material and examination of
holotype and paratypes of the reference species
(especially regarding ontogeny of spiral cords) could
maybe lead to describe a new species or subspecies for
the new recorded specimens.

Discussion. Calliotropis denticulus n. sp. is rather
close to C. reticulina (Dall, 1895) from off Hawaï and
Japan, but this species has a greater H/H ratio, beads
of P3 and P4 much broader and less numerous and a
less wide umbilicus.
The new species is also close to C. abyssicola Rehder
& Ladd, 1973 from Central Pacific, but this species 1s
different for the same reasons as them relative to C.
reticulina; moreover, this species has a canaliculated
suture.
C. denticulus n. sp. remembers C. keras n. sp. (Figs
212-213) from Fiji and Tonga, but this similar in size
species has a more depressed spire, thicker cors on the
whorls, less numerous and different in shape spiral
cords on the base and a narrower umbilicus.
Etymology. Lace (Latin), used as a noun in apposition
- with reference to the delicate scultpture of the shell.

using also the material examined by Marshall, 1979).
Remarks. Following the original description, the
main distinguishing features of C. delli Marshall, 1979
are a very small size (height about 3.5 mm), a
moderately elevated spire with up to 6.5 whorls, 2
nodular, similar in size spiral cords on whorls (more
explicitly : PI at adapical third, separated from the
suture by a subsutural ramp, P2 absent and P3 nearly
peripheral at abapical quarter), axial ribs on the whole
surface (primary axial ribs widely spaced, narrower
secondary ribs in the subsutural ramp), 4 or 5 granular
spiral cords on the base, a deep, rather narrow
umbilicus with one thin beaded spiral cord inside, an
aperture inclined backward.

New records and new species of Calliotropis from Indo-Pacific
l don't know any other reference to this species and
there is no indication about the variability of the shell.
Specimens studied here match the original description,
except that P3 is not so low on the whorls (at abapical
third instead quarter) and a P4 is clearly visible on last
whorl (the original description doesn't state explicitly
the presence of P4, but use a "3d spiral" as reference
of extension of the axial ribs). Also some specimens
have only 3 spiral cords on the base (e.g. specimens
BATHUS 4, stn DW914, stn DW9I8 and stn
DW927), but maybe the original description took into
account of basal cords the last spiral cord P4 of the
last whorl. Anyway, informations about animal are
lacking and the small differences regarding the shells
seem not enough to justify a categorisation of these
specimens into a new species.

Discussion. Calliotropis pyramoeides n. sp. is close to
C. grata Thiele, 1925 from eastern Africa, but this
similar in size species has a cyrtoconoidal shape, P2
closer to P3 than to PI, 4 spiral cords on the base and
no visible spiral cords inside the umbilicus; the beads
of P2 are smaller than those of the new species and are
only scaly, not sharp.
The new species may also be compared to C. muricata
(Schepman, 1908) (Figs 70-71) from Indonesia, but
36
this species has a cyrtoconoidal shape, 4 spiral cords
on last whorls with not spiny beads and two
columellar denticles.
C. pyramoeides n. sp. also weakly remembers C.
malapascuensis Poppe, Tagaro & Dekker, 2006 from
Philippines, but this species has nodules of PI and P2
that are much stronger, of the same size and not spiny
nor scaly; it has only one spiral cord inside the
umbilicus.

New records and new species of Calliotropis from Indo-Pacific
Discussion. The combination of a small size, a
coelonoïdal spire and a missing P2 makes Calliotropis
coopertorium n. Sp. hard to confuse with another
Calliotropis species, except maybe with C. echidna
Jansen, 1994 (Figs 68-69) from eastern Australia, but
this species has a spire with a first part coeloconoïdal
and second part cyrtoconoidal, and 4 thick spiny spiral
cords (P2 is present).
Etymology. Cover (Latin : coopertorium, -1), used as
a noun in apposition - after the shape of the spire of
the shell remembering the cover of an arabian pan.

Table 16. - Calliotropis oros : Shells measurements in mm for types.
Discussion. The combination of a small size, a nearly
conical spire and a large area between PI and P3
makes Calliotropis oros n. sp. hard to confuse with
another Calliotropis species, except maybe with
C. scalaris Lee & Wu, 2001 (Figs 116-119) from
South China Sea and Indonesia, but this slightly
bigger species has a cyrtonoidal spire with more
convex whorls, a P3 not so close to P4 (at second third
of whorl), no tertiary cords, less spiral cords on the
base and no spiral cord inside the umbilicus.
Regarding the number of spiral cords on the whorls
and on the base, the new species may also be
compared to C. abyssicola Rehder & Ladd, 1973
from central Pacific, but this bigger species has a
cyrtonoidal spire with more convex whorls, a
intermediate primary cord nearly median on the
whorls and no spiral cord inside the umbilicus.
Regarding the conical shape of the shell, €. oros n. sp.
may remember C. reticulina (Dall, 1895) from
Hawaii and Japan, but in this slightly larger species,
P2 is not lacking and there is no spiral cord inside the
umbilicus.
The new species may also remember C. francocacii
Poppe, Tagaro & Dekker, 2006 from Philippines, but
this similar in size species has a more elevated spire, a
nearly median intermediate primary cord, beads of the
three primary cords bigger and less numerous, no
tertiary spiral cords between P3 and P4 and only 4
spiral cords on the base.
Etymology. Mountain (Greek : opoc), used as a noun
in apposition - with reference of the more or less
conical shape of the shell.

Distribution. South-western Pacific (from
Chesterfield to New Caledonia), 980-1080 m.
Diagnosis. A rather small Calliotropis species with a
moderately elevated, about conical spire, broad
protoconch and convex whorls, white or brownish
white, with 2 main granular spiral cords on spire
whorls, up to 4 granular spiral cords on last whorl, the
abapical main cord peripheral; base with 6 granular
spiral cords; broad umbilicus without spiral cord
inside.
Description. Shell of moderate size for the genus
(height up to 5.8 mm, width up to 7.6 mm), broader
than high, rather thin, conical to slightly
cyrtoconoidal; spire moderately elevated, height 0.8x
width, 3.9x to 4.6x aperture height; broad umbilicus.
Protoconch from 360 to 400 um, of at least 1 whorl,
glassy, dome shaped, without clearly visible terminal
variX.
Teleoconch up to 5 convex whorls, bearing up to 4
spiral granular cords; nodules from cords produced by
intersections With axial ribs; axial sculpture still
visible, but weak, on last whorls.
Suture impressed, canaliculated except on last whorls.
First whorl convex, sculptured by 12 to 14, orthocline,
smooth, moderately thick ribs; interspace between ribs
2.5x to 3x broader than ribs; primary spiral cords P1
appearing almost immediately and P2 half a whorl
later, similar in size. On second whorl, P2 stronger
than P1; axial ribs slightly broader, interspace between
ribs 2.5x broader than ribs. On third whorl, PI and P2
stronger; beads of cords bluntly sharp; P3 emerging
weakly from suture at end of whorl, granular, smaller
than P3. On fourth whorl, PI and P2 much stronger
and axial threads weaker than on preceding whorl;
sharp beads of PI oriented at about 75°, sharp beads
of P2 slightly thicker and oriented at 45°, beads of P3
weaker, more numerous and more closely packed than
those of PI and P2. On last whorl, SI appearing on
most specimens, much weaker than P1 and P2, nearly
smooth for half a whorl, weakly granular at end of
whorl; P3 weaker then P2, peripheral.
C. VILVENS
Aperture subcircular to subelliptic; outer lip thin,
meeting inner lip with an obtuse, marked angle.
Columella more or less straight, oblique, without
tooth.
Base convex, with 6 rather granular spiral cords,
similar in size except the third (counting from the
outermost) thinner and the innermost slightly stronger,
bordering umbilicus; distance between cords from 1x
to 1.5x size of cords; axial ribs between spiral cords,
connecting beads of innermost cords.
Umbilicus broad, diameter ca. 30% of shell width,
deep, funnel shaped, with rather strong axial ribs and
without spiral cord inside.
Colour of teleoconch and protoconch nacreous white.
Discussion. Calliotropis hysterea n. sp. may
remember juvenile specimens of C. derbiosa Vilvens,
2004 from south-western Pacific, but this species has
a more elevated spire, its beads of the spiral cords of
the whorls and of the base in this species are much
more rounded and more closely packed, the axial ribs
are stronger and much more close.
The new species is rather close to C. calatha (Dall,
1927) from western Atlantic, but this bigger species,
of which the extreme variability was pointed out by
Quinn (1979), has a spiral cord P2 with more
numerous, more closely packed, only weakly sharp
beads, and only 3 or 4 spiral cords on the base.
Etymology. Late (Greek : votepeoc) - with reference
to the spiral cord SI appearing late.

Distribution. South-western Pacific (from New
Caledonia to Fiji), alive at 425 m, shells in 305-403 m:
Taïwan, 246 m.
Diagnosis. A small Calliotropis species with a
moderately elevated, a cyrtoconoidal spire, white or
brownish white, with 2 main granular spiral cords on
spire whorls, up to 5 granular spiral cords on keeled
last whorl, the abapical main cord peripheral: base
with 3 granular spiral cords: broad umbilicus with 3
spiral cords inside.
Description. Shell of small size for the genus (height
up to 4.8 mm, width up to 6.1 mm), broader than high,
moderately thick, slightly cyrtoconoidal; spire
moderately elevated, height 0.7x to 0.8x width, 4.4x to
5.4x aperture height: broad umbilicus.
Protoconch of about 150 um, of 1 whorl, bulbous,
without clearly visible terminal varix.
Teleoconch up to 5.7 convex whorls, bearing 6 spiral
granular cords different in size; nodules from cords
produced by intersections with axial ribs: axial
sculpture still visible on last whorls.
Suture impressed, weakly canaliculated.
First whorl convex, sculptured by 12 or 14 weakly
prosocline smooth, moderately thick ribs, interspace
between ribs about 2x broader than ribs: primary
spiral cords PI and P3 appearing at end of whorl,
poorly distinct, similar in size. On second whorl, P3
stronger than P1, P1 still rather indistinct: axial ribs
slightly broader, interspace between ribs 2x broader
than ribs. On third whorl, P1 and P3 stronger: beads of
cords bluntly sharp; P2 absent. On fourth whorl, P1
and P3 much stronger, with very different shape :
nodules of P3 sharp, sometimes scaly, orizontally
oriented, and nodules of PI thicker, bluntly sharp,
axially elongated, oriented at 45°; thin axial threads
appearing on the subsutural ramp; P4 emerging
weakly from suture at end of whorl, granular, smaller
than P3. On fifth whorl, S1 appearing, granular, much
weaker than P1 and P3: P1 dividing in two cords half
a whorl later: sharp beads of P3 more numerous and
more closely packed than nodules of PI. On last
whorl, P4 only slightly weaker then P3, giving a
bicarinate shape to the whorl.
Aperture subelliptic, possibly slightly declivous
(paratypes); outer lip rather thick, meeting inner lip
with an obtuse, poorly marked angle.
Columella curved in the middle, slightly reflected into
umbilicus, with a weak basal tooth in largest
specimens (paratypes).
Base moderately convex, with 3 rather thick granular
spiral cords; innermost cord slightly stronger: distance
between cords similar in size to cords; axial ribs
between spiral cords, connecting beads of cords.

Discussion. Calliotropis zone n. sp. 1s close to C.
(Schepman, 1908) (Figs 70-71) from
Indonesia, but this similar in size species has a more
elevated spire, similar thick, blunt beads on the
adapical and abapical main spiral cords, a more
convex base and only 2 spiral cords inside the
umbilicus.
The new species may also be compared to C.
cycloeides n. sp. (Figs 102-105) from Fiji and New
Caledonia, but this species has broader protoconch, a
different ontogeny of cords (especially with PI
appearing very late) and a spiral cord P3 with very
spiny, widely spaced nodules.
The new species is also superficially similar to C.
eucheloides Marshall, 1979 (Figs 138-155, 160-161)
from Indo-Pacific, but this slightly larger species has a
muricata
Figures 156-161
very different general shape with bell-shape last
whorls and a prominent adapical, peripheral spiral
cord with closely packed, axially elongated beads; this
widespread species has 6 spiral cords on the base.
Remarks. One can wonder about the Taiwanese
record of this new Caledonian species, but the
specimen, although encrusted, shows clearly the
descriptive ontogeny of the spiral cords at the same
time on the whorls, on the base and inside the
umbilicus.
Etymology. Crossbelt (Greek : Covn), used as a noun
in apposition - with reference to the strong peripheral
spiral cord on the last whorl of the shell.

but this taller, rather variable species has a conical, not
cyrtoconoidal, shape, a subcircular aperture and a
broader umbilicus; moreover, it lacks the spiral cord

The new species may remembers C. carinata Jansen,

Discussion. The combination of a moderately
depressed spire, a spiral cord P3 with strong spiny
scales, a flat base with 3 thick granular spiral cords
and a broad umbilicus with 2 spiral cords within
makes Calliotropis cycloeides n. sp. hard to confuse
with another Calliotropis species, except with C.
gemmulosa (A.Adams, 1860) from Japan and
Philippines (see Higo, Callomon & Goto, 2001, for an
illustration of the MNH holotype), but this species has
a cyrtonoidal shape, much more convex whorls and a
broader umbilicus with only one spiral cord inside.
C. cycloeides n. sp. is rather close to C. sagarinoi
Poppe, Tagaro & Dekker, 2006 from Philippines, but
this species has a less elevated spire, a cyrtoconoidal
shape, only 2 spiral cords on the base and no spiral
cord inside the umbilicus. Specimens of the new
species from Solomon Islands are more depressed as
specimens from Fiji and New Caledonia, being more
similar to C. sagarinoi, but they keep the
characteristic 3 spiral cords on the base and 2 spiral
cords inside the umbilicus.
The new species may remember C. bucina Vilvens,
2006 (Figs 106-107) from Réunion and Mayotte
Islands, but this species is a bit smaller for a similar
number of whorls and has more convex whorls, a
cyrtoconoidal shape, a spiral cord SI always present
and a spiral cord P3 that is the only one strongly
spiny.
Etymology. Wheel shaped (Greek : kvkAoc) - after the
general shape of the shell, evoking a toothed wheel.

Remarks about three related species.
Some authors (e.g. Poppe et al., 2006) have pointed
out that some confusion exists between the three
species Calliotropis calcarata (Schepman, 1908) (Figs
156-157, 162-167) from Indonesia, C. galea (Habe,
1953) (Figs 80-83, 158-159) from Japan and C.
eucheloides Marshall, 1979 from Indo-Pacific.
Regarding the original descriptions and material from
types or certified specimens, the differences between
the three species seems nevertheless rather clear
('i:Pj-Pk" below means "spiral cords Pi and Pj appear
at whorl #i" and "1:Pj/2" means "spiral cord Pj divides
in two cords at whorl #i"') :
+ C. calcarata has a depressed spire, with 6 even
spaced spiral cords on the last whorl (1:P1-P3; 3:P2-
P4; 4:S1, S2) with granules of P4 sharp, not axially
elongated, at most a very weak columellar basal tooth,
7-8 granular spiral cords on the base, a wide umbilicus
with 1 spiral cord inside.
+ C. galea has also a rather depressed spire, 5 spiral
cords on the last whorl (1:P1-P2; 3:P3; 4:S1:6:P1/2)
with granules of P3 axially elongated (prosocline
shape of ribs) and distance between adapical cords
smaller than distance between abapical cords, a weak
columellar basal tooth, 6 granular spiral cords on the
base, a wide umbilicus with 1 spiral cord inside.
+ C. eucheloides has a more elevated spire, 5 spiral
cords on the last whorl (1:P1-P2; 3:P3, S1;5:P1/2)
with granules of P3 axially elongated (prosocline
shape of ribs) and distance between adapical cords
smaller than distance between abapical cords, a strong
(sometimes acute) columellar basal tooth, a base with
6 granular spiral cords or nearly smooth (all
intermediates exist), a wide umbilicus with 1 spiral
cord inside.
Poppe et al. (2006) suspected however that C.
eucheloides could be a synonym of C. calcarata. They
described from Philippines an additional species
C. VILVENS
related to these three (?) species : C. virginiae Poppe,
Tagaro & Dekker, 2006, close to C. galea but said to
be different by the shape of the spire, the whorls and
the beads of the spiral cords.
Remarks on the variation of C. eucheloides.
On the other hand, C. eucheloides brings another
problem, that is its high variability regarding the
height of the shell and moreover the sculpture of its
base. In the studied material (see list below), high
variations for the basal sculpture were indeed found.
Some of studied specimens (including also material
from Philippines provided by malacologists-dealers as
G. Poppe and F. Dedonder), show the typical
characters of the species - let's talk about these
specimens as belonging to the "typical form", with 6
granular basal spiral cords and a spiral cord inside the
umbilicus (Figs 138-145). This is the single form that
can found outside the New Caledonia area throughout
the western Pacific Ocean and the Indian Ocean. But
some other specimens collected in New Caledonia and
Loyalty Islands area seemed however, at first look, to
belong to another species, because they have
+ _a smooth base instead basal granular spiral cords:
+ no spiral cord within the umbilicus:
+ aspire slightly more elevated (ratio H/W larger).

- let's talk about these specimens as belonging to the
"smooth form" (Figs 152-155).
A first look to the distribution of the two kinds of
specimens reveal that there is no geographic
separation between them : the two kind of shells were
found together in 5 stations of similar depth from New
Caledonia and Loyalty Islands.

the umbilicus. Such specimens occur in the same New
Caledonia and Loyalty Islands area. Two of the three
forms were found together in 5 stations of the same
area, at similar depth.

New records and new species of Calliotropis from Indo-Pacific
The conclusion that only anatomical studies may
prove definitively that there is here only one species or
two; so, we keep provisionally all the specimens
examined here under the only name given by
Marshall. Such conchological variations among
specimens of the same species are not really a wonder:
for example, Calliotropis calatha (Dall, 1927) from
western Atlantic is in the same way also extremely
variable (Quinn, 1979: 9-13, figs 15-20).
Material examined. (tf. — typical form; if. =
intermediate form; s.f. = smooth form).

Diagnosis. A rather tall, moderately depressed, nut-
brown Calliotropis species with a cyrtoconoïidal spire,
a shoulder at first third, 4 granular spiral cords on
whorls, the abapical cord the strongest; prosocline thin
treads between the two abapical cords: base with
about 5 granular, rather thick spiral cords; rather large
umbilicus with a weak spiral cord inside.
Description. Shell rather large for the genus (height
up to 11.0 mm, width up to 14.8 mm),
broader than high, rather thin, cyrtoconoidal; spire
moderately depressed, height 0.7x width, 4.0x to 4.6x
aperture height; rather broad umbilicus.
Protoconch of about 400 um, of 1 whorl, dome-
shaped, without terminal varix.
Teleoconch up to 6.3 convex whorls, bearing up to 4
spiral granular cords; nodules from cords produced by
intersections with axial ribs; secondary thin axial ribs
on abapical part of last whorls.
Suture impressed, canaliculated.
First whorl convex, sculptured by 20 almost orthocline
smooth ribs, interspace between ribs 2x broader than
ribs; primary spiral cords P2 and P3 appearing almost
immediately, granular; P2 weaker than P3. On second
whorl, P2 and P3 thicker, P2 slightly weaker than P3,
making shoulder; beads of P2 bluntly sharp, beads of
P3 more acute. On third whorl, P3 still slightly
stronger than P2; PI appearing at end of whorl,
quickly similar in size to P2; P4 emerging from suture
at end of whorl, granular, similar in strength to P2. On
fourth whorl, beads of P3 strongly sharp, beads of PI
and P2 rounded; axial ribs still present, thick. On fifth

Columella straight, slightly oblique, without basal

Base slightly convex, with 5 or 6 granular, rather thick
spiral cords, innermost cord slightly stronger and
bordering umbilicus; distance between cords more or
less similar in size to cords; weak axial ribs between
cords.
Umbilicus rather broad, diameter ca. 25% of shell
width, deep, funnel shaped, with low axial ribs and
with an indistinct spiral cord inside.
Colour of teleoconch and protoconch nut-brown.
Table 22. - Calliotropis nux : Shells measurements in mm for types and specimen.
Discussion. The peculiar combination of a rather big
size, evanescent P2 and P3 and a belt of prosocline
threads between P3 and P4 reduce the number of
species that could be compared with the new species.
Calliotropis nux n. sp. is close to C. midwayensis
(Lan, 1990) (Figs 88-95) from Central Pacific and
South China Sea, but this similar in size species keeps
only PI and P4 on last whorl, has no shoulder, lacks
thin, prosocline threads above P4 and has thinner,
smooth (instead of granular) spiral cords on the base.
The new species remembers a litlle C. g/ypta (Watson,
1879) (Figs 204-207) from eastern Australia, but this
taller species has a slightly more elevated spire, much
stronger P2 and P3 without shoulder and the whole
surface covered by prosocline threads (not only
between P3 and P4).
Etymology. Walnut (Latin : nux, -cis), used as a noun
in apposition - with reference to the colour of the
shell.

Remarks. This species was originally described from
south-western Philippines (near Indonesia). One can
wonder about these new records in Pacific, far from
the type locality and giving so a disjoint distribution,
but the specimens here examined are similar to the
holotype and match the original description, except
that they lack the basal columellar tooth. This could be
explained by the reduced number of whorls (4.6 for
the largest specimens) regarding the 5.5 whorls of the
examined holotype : the Pacific specimens could be
not fully adult. More material is necessary to state if
this is the same species or a different one.

Distribution. Marquesas Islands, alive in 500-660,
shells in 408-1150 m.
Diagnosis. A small Calliotropis species with a
moderately elevated, slightly cyrtoconoidal spire,
white or brownish white, with 2 main granular spiral
cords on spire whorls, the adapical cord close to suture
and the other at third quarter of the height of whorl;
additional weaker, granular spiral cords between the
two main cords and an additional, peripheral, granular
spiral cord on last whorl; base with 7 granular spiral
cords; broad umbilicus usually without spiral cord
inside.
Description. Same features as Calliotropis oros oros
n. Sp. differing from it by a slightly larger size
comparing to the number of whorls (height up to 7.0
mm, width up to 10.0 mm, teleoconch up to 5.6
convex whorls), a more depressed spire (height 0.6x to
0.7x width) and a lesser number of slightly thicker
beads for P3 and P4 on fourth whorl.

Table 23. - Calliotropis oros marquisensis : Shells measurements in mm for types.
Discussion. Calliotropis oros marquisensis n. ssp.
seems to have constant features that distinct it from C.
oros oros n. Sp. (Figs 120-123). Because no
intermediate forms were found, especially in the area
beween Fiji Islands and Marquesas Islands, we
consider provisionnally that these two subspecies are
different, although further studies on additional
material could show that there is only one variable
species.
Etymology. From the Marquesas Islands (Latin) -
with reference to the Marquesas Is. ("Marquises" in
52
French) that are the characteristic area of the
subspecies.

Diagnosis. A rather big white Calliotropis species
with a rather depressed, slightly cyrtoconoidal spire
and an angular periphery, 2 granular spiral cords on
first spire whorls and 5 granular spiral cords on last
whorls; size of beads of cords decreasing in size from
adapical part to abapical part; thin, crowded, strongly
prosocline threads between cords; base more or less
flat with S flat spiral cords: broad umbilicus with one
thin spiral cord inside.
Description. Shell of rather big size for the genus
(height up to 13.6 mm, width up to 19.2 mm), much
broader than high, rather thin, slightly cyrtoconoidal:
spire moderately depressed, height 0.6x to 0.7x width,
2.1x to 3.2x aperture height; broad umbilicus.
Protoconch damaged or strongly encrusted in all
available specimens, estimated of about 350 um.
Teleoconch up to 6.7 convex whorls, bearing 5 spiral
granular cords different in size; nodules from cords
produced on first whorls by intersections with axial
ribs; axial sculpture on last whorls consisting in thin,
crowed, strongly prosocline threads in area between
spiral cords.
Suture visible, canaliculated.
First whorl convex, sculptured by about 15 slightly
prosocline smooth, ribs; interspace between ribs from
1.5x to 2x broader than ribs; primary cord P3
NOVAPEX 8 (HS 5): 1-72, 10 juin 2007
appearing almost immediately; P2 appearing at mid
whorl, weaker than P3. On second whorl, P2 and P3
stronger, beads of cords somewhat sharp. On third
whorl, PI appearing, quickly as strong as other cords;
P2 closer to PI than to P3; interspace between ribs
from 2x to 2.5x broader than ribs; beads of cords
similar in size. On fourth whorl, P1 dividing into two
similar cords; beads of P3 slightly more numerous
than those of other cords: P4 emerging partially from
suture, beads much more smaller and more numerous
than those of P3; primary axial sculpture becoming
obsolete, crowded prosocline threads appearing in
whole area between P3 and P4, some similar threads
appearing between P2 and P3. On last whorls, P4
peripheral: beads of spiral cords decreasing in strength
and size from adapical to abapical cord, crowded
beads of P4 about 2x more numerous and smaller than
those of Pl; thin, prosocline threads present on the
whole surface between all cords.
Aperture subelliptic, horizontally elongated: outer lip
thin, meeting inner lip with an obtuse, poorly marked
angle.
Columella more or less straight, oblique, without
tooth.
Base almost flat, with 5 granular spiral cords,
outermost cord the strongest, innermost cord stronger
than other inner cords, bordering umbilicus;
intermediate cords sometimes very obsolete: distance
between cords decreasing from 2x size of cords for
outer cords to 1x for inner cords; axial ribs between
spiral cords very weak, giving to interspaces a smooth
appearance.
Umbilicus very wide, diameter ca. 35% of shell width,
deep, funnel shaped, with
steep sloping walls and one weak, subgranular spiral
cord within.
Colour of teleoconch and protoconch light brown.
holotype
paratype MNHN
specimen CP1420
Table 24. - Calliotropis keras : Shells measurements in mm for types and some specimen.
Discussion. Considering thin, crowded axial threads
on the whorls, Calliotropis keras n. sp. remembers C.
glypta (Watson, 1879) (Figs 204-207) from Australia,
but this species has a more elevated spire, a spiral cord
P2 much more weaker than the other cords and more
numerous spiral cords on the base.
The new species is also rather close to C. derbiosa
Vilvens, 2004 (Figs 74-75) from Vanuatu and Fiji, but
this bigger species has a much higher spire, stronger
spiral cords on the base and no spiral cord inside the
umbilicus.
Calliotropis keras n. sp. may be compared to C.
abyssicola Rehder & Ladd, 1973 from central Pacific,
but this species is not so depressed, has a more
rounded periphery, more numerous, more
concentrated spiral cords on the base towards the
umbilicus and has no spiral cord inside the umbilicus.
Remarks. The specimen from Tonga has on last
whorl an additional tertiary spiral cord between the
divided in two parts PI and P2.
Etymology. Horn (Greek : kepac), used as a noun in
apposition - with reference to the conical shape of
spire and and the funnel shaped umbilicus.

Discussion. C. elephas n. sp. is close to C.
concavospira (Schepman, 1908) (Figs 246-247) from
Indonesia, but this slightly smaller species has thinner
spiral cords on the whorls with beads of P3 smaller
and much more spaced, a rounded, not elongated,
aperture, and thinner spiral cords on the base, all
granular with thin axial threads between cords.
The new species is also rather close to C. gemmulosa
(A.Adams, 1860) from Japan and Philippines, but this
smaller species has a more elevated spire, 4 (not 3)
spiral cords on the last whorl and 3 spiral cords on the
base, all granular.
Regarding the number of cords, C. elephas n. sp.
remembers C. carinata Jansen, 1994 (Figs 184-185)
from eastern Australia, but this species has a more
elevated spire, beads of P3 much more spaced,
thinner, all granular spiral cords on the base with well
spaced beads and numerous axial threads between
cords.
The new species may be compared to C. basileus
Vilvens, 2004 (Figs 76-79) from Fiji and New
Caledonia, but this larger species has a more elevated
spire, beads of P3 much more spaced and 4 (not 5)
spiral cords on the base with a granular (not smooth)
external cord.

very broad umbilicus.
Protoconch of about 270 um, of 1 whorl, without
terminal varix.
Teleoconch up to 6.1 convex whorls, bearing to 2
spiral granular cords different in size; nodules from
cords produced by intersections with axial ribs; axial
sculpture on first whorls, reduced to adapical part on
last whorls.
Suture impressed, not canaliculated.
First whorl convex, sculptured by about 15 prosocline
smooth ribs; interspace between ribs from 1.5x to 2x

Table 26. - Calliotropis rostrum : Shells measurements in mm for types.
Discussion. The combination of a depressed spire and
a large smooth area between PI and P4 avoids any
confusion with any known Calliotropis species. The
closer one could be C. bicarinata (Schepman, 1908)
(Figs 218-219) from Indonesia but this smaller species
has a more elevated spire, a thick, scaly spiral cord P3,
a spiral cord P4 thicker than the one of the new
species and 3 thick spiral cords on the base.
Etymology. Ram of an ancient warship (Latin), used
as a noun in apposition - with reference to the shape of
the last whorl with a prominent peripheral spiral cord.

Diagnosis. A pearly grey Calliotropis species of
medium size, with a slightly cyrtoconoidal, depressed
spire, an angulated periphery and up to 3 granular
spiral cords on whorls, the intermediate cord
disappearing on last whorls while the abapical cord
grows; abapical cord making a strong keel on last
whorl; base smooth except 1 (or sometimes 2)
granular spiral cord around umbilicus; one basal
columallar tooth; broad umbilicus without spiral cord
inside.
Description. Shell! of medium size for the genus
(height up to 10.2 mm, width up to 18.1mm),
much broader than high, slightly cyrtoconoidal; spire
depressed, height from 0.5x to 0.6x width, 3.5x to
3.8x aperture height; broad umbilicus.
Protoconch of about 350 um, of 1 whorl, without
terminal varix.
Teleoconch up to 6.3 moderately convex whorls,
bearing 2 spiral granular cords different in size on first
whorls, 3 cords on intermediate whorls and 2 cords on
last whorls; primary axial sculpture only visible on
first whorls.
Suture impressed, canaliculated.
First whorl convex, sculptured by about 15 orthocline
smooth ribs; interspace between ribs from 1.5x to
quickly 2.5x broader than ribs; primary cords PI and
P3 appearing almost immediately, granular; nodules
from cords produced by intersections with axial ribs:
P3 slightly stronger than PI. On second whorl, beads
of both cords stronger, beads of P3 sharper than those
of PI; axial ribs slighity prosocline, broader but lower.
On third whorl, P4 emerging partially from suture at
end of whorl, granular; beads of P4 smaller and more
numerous than nodules of P3; P2 absent; axial ribs
vanishing. On fourth whorl, P3 weakening and P4
fully emerging from suture, becoming stronger than
P3; bead of P4 smaller than those of PI, bluntly sharp,
scaly. On next whorls, beads of PI thick, sharp,
almost vertically oriented; bead of P4 2x to 3x more
numerous than those of Pl: P3 disappearing. On last
whorl, P4 peripheral, making keel; beads of P4
crowed, vertically elongated.

Discussion. Regarding the peculiar ontogeny of cords
(especially of P3), the new species remembers only
Calliotropis midwayensis (Lan, 1990) (Figs 88-95)
from Midway Islands and Taiwan, but this species has
a more elevated spire, more convex whorls and 6 or 7
thin spiral cords on the base.
Regarding the general shape of the shell, C. nomisma
n. sp. 1s rather close to Basilissa sibogae Schepman,
1908 from Indonesia, but this species is smaller for a
similar number of whorls, has a much more elevated
spire and a numerous spiral cords on the whole base.
Etymology. Medal (Greek : vouioua), used as a noun
in apposition - with reference to the depressed shape
of the shell.

Remarks. This species was originally described from
south-western Indian Ocean. One can wonder about
these new records in Pacific, in two different areas,
very far from the type locality and giving thus a
disjoint distribution in three segments. Nevertheless,
the specimens here examined are similar to the types
58
and match the original description, except that they
seem a little more depressed and that S2 appears a bit
later. C. bucina Vilvens, 2006 is rather close to C.
sagarinoi Poppe, Tagaro & Dekker, 2006 from
Philippines, but this species has a less depressed spire,
lacks the spiral cord S2, has only 2 (instead of 3)
spiral cords on the base and has no spiral cord inside
the umbilicus.

(height up to 5.0 mm, width up to 7.3 mm), broader
than high, rather thin, cyrtoconoidal; spire moderately
elevated, height 0.5x to 0.7x width, 3.9x to 4.3x
aperture height; broad umbilicus.
Protoconch from 350 to 360 um, of about 1 whorl,

Table 28. - Calliotropis stegos : Shells measurements in mm for types.
Discussion. Calliotropis stegos n. sp. is rather close to
C. hysterea n. sp. (Figs 134-137) from New
Caledonia, but the latter has an almost conical shape,
beads of P2 thicker and more spaced, a bigger
protoconch and a secondary cord SI.
The new species is superficially similar to C. scalaris
Lee & Wu, 2001 (Figs 116-119) from South China
Sea and Indonesia, but this slightly larger species has
a more globular shape with a less H/W ratio and
stronger nodules of P1 and P2.
Regarding the number of spiral cords on the whorls,
the new species weakly remembers C. francocacii
Poppe, Tagaro & Dekker, 2006 from Philippines, but
this similar in size species has a more elevated spire,
thicker nodules on the spiral cords PI and P2, a
rounded periphery and only 5 thinner spiral cords on
the base.
Also considering the number of spiral cords, C. stegos
n. sp. may be compared to C. wilsi Poppe, Tagaro &
Dekker, 2006 from Philippines, but this species has a
more elevated, slightly coeloconoïidal spire, a
significant keel on P2, much thicker, more spaced
nodules on all the spiral cords and only at most 5
spiral cords on the base.

Table 29. - Calliotropis cooperculum : Shells measurements in mm for types.
Discussion. Calliotropis cooperculum n. sp. shares a
similar ontogeny of cords with C. hysterea n. sp. (Figs
134-137) from New Caledonia, but this similar in size
species has a much higher spire, a conical shape, PI
and P2 similar in size and thicker, and more distinct
basal spiral cords.
The new species is also rather close to C. gemmulosa
(A.Adams, 1860) from Japan and Philippines, but,
again, this similar in size species has a higher spire
and spiral cords on whorls that are similar in size;
moreover, the new species has thicker and fewer (only
3 or 4) basal spiral cords.
C. cooperculum n. sp. may be compared to C.
abyssicola Rehder & Ladd, 1973 from central Pacific,
but this species is taller for a same number of whorls,
has a cyrtoconoïidal shape and similar in size spiral
cords on the whorls.
The new species may also be compared to some forms
of the variable C. calatha (Dall, 1927) from western
Atlantic, but this more or less similar in size species
has a more elevated spire and only 3 or 4 spiral cords
on the base.

apposition - after the shape of the spire of the shell
remembering the cover of a pan.

Diagnosis. A small, depressed, nacreous white
Calliotropis species with a more or less conical spire,
a small protoconch, 2 granular spiral cords on spire
62
whorls, the adapical with sharp beads and the other
making a keel: an additional peripheral spiral cord on
last whorl giving a bicarinate shape to the shell; base
with 4 granular spiral cords; broad umbilicus with one
spiral cord inside.
Description. Shell of small size for the genus (height
up to 2.9 mm, width up to 4.5 mm), much broader
than high, rather thin, conical to slightly
cyrtoconoidal; spire depressed, height from 0.6x to
0.7x width, 3.0x to 4.3x aperture height; broad
umbilicus.
Protoconch from 200 to 250 pm, of 1 whorl, glassy,

Teleoconch up to 4.5 slightly convex whorls, bearing
up to 3 spiral granular cords; nodules from cords
produced by intersections with axial ribs on first
whorls; axial sculpture on spire whorls, weaker on last
whorl.
Suture visible, canaliculated.
First whorl convex, sculptured by about 15 weakly
prosocline smooth ribs; interspace between ribs about
2x broader than ribs; primary cord P3 appearing
almost immediately, PI appearing half a whorl later,
weaker than p3. On second whorl, P3 stronger than
Pl; beads of P3 strong and sharp. On third whorl,
beads of PI and P3 sharp, beads of PI 1.5x more
numerous than beads of P3; beads of PI almost
vertically oriented; area between PI and P3 more or
less straight, P3 making keel; axial ribs stil connecting
beads of cords, but becoming weaker. On fourth
whorl, P4 emerging weakly from suture, granular,
with beads smaller than beads of P1; P2 absent; axial
sculpture obsolete. On last whorl, P4 peripheral,
making a second keel, with beads slightly smaller and
more numerous than those of P3; P3 more or less
median between P1 and P4.
Aperture subcircular, inclined backward; outer lip
thin, meeting inner lip without angle; inner lip flanged

Discussion. Calliotropis trieres n. sp. is rather close to
C. ostrideslithos n. sp. (Figs 214-217) from Solomon
Islands, but this slightly broader species has a larger
protococonch, stronger beads on P3, 3 spiral cords and
thinner, more crowded axial threads within the
umbilicus.
The new species may also remember C. cooperculum
n. sp. (Figs 190-193) from Fiji, but this larger species
has a larger protococonch, stronger and sharper beads
on PI, no keel at P3, a concave (not straight) area
between P1 and P3 and a not inclined aperture.
C. trieres n. sp. is may be compared to C. carinata
Jansen, 1994 (Figs 184-185) from Eastern Australia,
but this larger species has a more elevated spire, much

Discussion. The new species is close to Calliotropis
vilvensi Poppe, Tagaro & Dekker, 2006 (Figs 222-
223) from the Philippines and C. pheidole n. sp. (Figs
224-227) from Fiji and Tonga, but these two smaller
species have less numerous spiral cords on the base (4
at most) and at least 2 spiral cords inside the
umbilicus.
C. siphaios n. sp. remembers C. eucheloides Marshall,
1979 (Figs 138-155, 160-161) from Kermadec Islands,
New Caledonia and Philippines, but this slightly larger
species differs by many features as a more elevated
spire, more numerous spiral cords on the whorls and a
columellar tooth.
Etymology. Buckwheat pancake (Greek : otpaioc),
used as a noun in apposition - with reference to the
depressed spire of the shell.

Table 34. - Calliotropis pheidole : Shells measurements in mm for types.
Discussion. The new species is close to Calliotropis
vilvensi Poppe, Tagaro & Dekker, 2006 (Figs 222-
223) from the Philippines, but this similar in size
species is much more depressed, has a P3 spiral cord
peripheral on the last whorl and a spiral cord P4 only
68
visible on this last whorl (instead of an absent P3 and
a peripheral P4 for the new species).
Additional material from various Indo-Pacific areas,
could prove that intermediate forms exist and that
there is only one species with a very large distribution.
