The Spondylidae in the historical collections of the Muséum d’Histoire Naturelle, Geneva,
with revision of the species described by Lamarck and by Chenu,
and notes on nomenclature
(Bivalvia: Pectinoidea: Spondylidae)

Abstract
The Museum d’Histoire naturelle, Geneva, holds most of the historical Spondylus collections of
Lamarck, Delessert and Chenu. These collections have recently been curated by first author (YF).
Resulting from this work, 32 species have been isolated, photographed and records made of the
status of the species; the location of the original illustrations (if any), as well as comments by early
curators at the MHNG, are included. 14 species described by Chenu are listed from the Delessert
collection. 16 species described by Lamarck are catalogued from both the Lamarck and Delessert
collections. Additionally, 2 linnean species, Spondylus gaederopus and Spondylus regius, are also
listed, with comments on the material contained in the Lamarck/Delessert collection.
Comparison of the type of Spondylus ambiguus Chenu 1844 with that of Spondylus ictericus
Reeve 1856, indicates that the latter is a junior synonym of the former and therefore Spondylus
ambiguus is a prior name for that species.
Key words: Spondylus, Spondylidae, Lamarck, Chenu, type material, nomenclature, Muséum
de Genève.

Introduction
Curatorial work at the Zoological Museum, University of Copenhagen, has recently catalogued six specimens of Spondylus from the Spengler and Moltke collection, which were figured in the Chemnitz Cabinet. This
has resulted in lectotypes being selected for Spondylus
foliaceus Schreibers 1793; Spondylus sinensis Schreibers 1793; Spondylus squamosus Schreibers 1793 (Lamprell & W illan , 2000), Spondylus croceus S chreib ers 1793 and Spondylus nicobaricus Schreibers 1793
(Lamprell & Dekker, 2001). The Museum of Evolution,
Uppsala, Sweden, now houses a syntype of Spondylus
regius Linnaeus 1758 (previously housed in the Museum
Ludovicae Ulricae); this specimen was selected as lectotype by Lamprell & Dekker, 2001.
The present paper, in isolating the historical specimens of that same period housed in the MHNG is of
major importance in establishing the nomenclature for
many Spondylid taxa. The study of the species described
by Lamarck in the collection of the MHNG is greatly facilitated by the handwritten annotations made by
Lamarck’s daughter Rosalie de Lamarck in the margin
of the original volumes of Anim. Sans Vert. which pertained to Lamarck. These notes and comments state how
many specimens were originally in her father’s collec-

were those chosen by Lamarck for his descriptions.
History of Lamarck and Delessert collections
Jean Baptiste Pierre Antoine de Monet, Comte de
Lamarck (to give him his full title) was appointed Professor of Zoology in the natural History Museum in
Paris. His collection of shells was one of renown but
the Paris Museum in France could not purchase it when
Lamarck was approaching the end of his life. We know
he tried to sell it to the Museum, as his daughter Rosalie de Lamarck prepared the collection for sale, using
Lamarck’s own volumes of Anim. Sans Vert. as a sale
catalogue by making handwritten annotations in the margin. This detailed the quantity of specimens present in
the collection for each species listed. But personal and
political problems and antagonisms like the one opposing Lamarck and Cuvier, prevented the Paris Museum
from buying the collection. After Lamarck’s death, the
collection was sold to Prince Masséna, L.C. Kiener becoming its scientific curator. In 1840, it was acquired by
Baron Jules Paul Benjamin Delessert (Dance, 1986;
Cailliez, 1995; Cailiez & Finet, 1997), who incorporated it in his own collection, which already held several
collections of different origins. Jean-Charles Chenu (a
medical practitioner) later replaced Kiener as curator
of the malacological collections of Delessert. Chenu
became a well-known malacologist, who edited the famous Illustrations Conchyliologiques ou Description
et figures de toutes les coquilles connues, vivantes et
fossiles, among many other publications. Many shells
from the Delessert collection were eventually described
as new species by Chenu, and figured by him in these
volumes. The collection of Benjamin Delessert was
then the largest private collection of molluscan shells in
the world, even outnumbering the malacological collections of the Paris Museum! Delessert illustrated many
specimens from Lamarck in his “Recueil de coquilles
décrites par Lamarck dans son Histoire naturelle des
Anim. Sans Vert., et non encore figurées” (Delessert
1841). When he died in 1847, the collection became the
property of his brother François Delessert who retained
it for twenty years, until his death in 1868. There was
then another attempt to allow the collection to go to the
Paris Museum, however we understand that the director
in charge of the Museum, Lacaze-Duthiers, was too
busy with the construction and funding of the biological research station at Roscoff, Brittany to consider the
proposition. The Delessert family had close and friendly
scientific relationships with several scientists of renown
in Geneva, among them Pictet de la Rive (1809–1872),
chief zoologist at the Academic Museum of the City of
Geneva, as well as with the famous botanist Alphonse
de Candolle (1806–1893). In addition, the Delessert
family was of Swiss origin from Canton de Vaud near
Lausanne, with one of the two daughters of François Delessert, Caroline, also married to a Swiss banker named
Hottinguer. Their combined efforts led to the acquisition
of the Delessert collection by the Academic Museum of
the City of Geneva, ancestor of the current Museum of
Natural History, in 1869.

R e m a r k s : Spondylus albus is a validation by Chenu
of the earlier non-binomial description by Chemnitz
(Conchylien Cabinet, Vol. 9 (1786), 1 st part: 143, pl.
115 figs 988–990). Actually, both the figured specimens
of Chemnitz, and the material of Chenu should be considered type specimens. According to the ICZN (article
72.4.4), if a species description “is made available by a
bibliographic reference to a description or definition associated with an unavailable name, [the type series] consists of or includes the specimen or specimens denoted by
that unavailable name.” Since the text states “or” (“consists of, OR includes”), it means that the type series can
also include other specimens available to the author, not
just the original Chemnitz’ specimen(s). Article 72.5.6 of
ICZN also clarifies that the type series is the specimen
illustrated, not the illustration itself (a change from prior
practice). Finally, article 73.2.1 explains that syntypes include “specimens not seen by the author but which form
the bases of previously published descriptions or illustrations upon which the author founded the new nominal
species-group taxon in whole or in part.” This confirms in
our case that Chemnitz’ specimens can be syntypes, even
if the author had other specimens (“in whole or in part”).

(figured herein, Plate 2 Figs 7–8), not figured in earlier literature, with a handwritten inscription by Lamarck on the inner
side of the shell; MHNG 1088/90/1-4 (4 pv) (figured herein,
Plates 3–4 Figs 9–17), none figured in earlier literature, with
a label by Lamarck, bearing the name “Spondylus americanus, Chemn. 7, t. 45, f. 465”; MHNG 1088/91 (1 pv) (figured
herein, Plate 5 Figs 18–19), figured by Chenu, pl. 5 fig. 2;
MHNG 1088/92/1-2 (var. b or c): 2 pv (figured herein, Plates
5–6 Figs 20–25, one of them (1088/92/1) figured by Chenu,
pl. 3 fig. 2–2 a. — D e l e s s e r t c o l l e c t i o n : 7 specimens,
all figured by Chenu, and with “Amérique” as locality on the
labels: MHNG 30683, 1 pv of “var. c”, figured by Chenu, pl.

MHNG 30697: 1 pv, figured by Chenu, pl. 3, fig. 3.
R e m a r k s : In the Lamarck collection, the specimens illustrated by Chenu are easily identifiable, but
this is not the case when comparisons are made with the
two Lamarck figures in the “Encyclopédie Méthodique”
(pl. 195, figs 1–2). None of the specimens present in the
Lamarck collection seem to have been illustrated with
Lamarck’s original description. In the original volumes
of Anim. Sans Vert. which pertained to Lamarck, his
daughter Rosalie made an annotation mentioning only
5 specimens (instead of 9) in her father’s original collection. The specimens currently in the Lamarck collection
thus have a questionable type status.

corresponding to fig. 2 (pl. 23) of Chenu, is in Paris Museum. However, it could be that the Paris specimen corresponds well to the species illustrated by Chenu, but is
not necessarily the same shell. There is no doubt that the
specimen illustrated by Chenu is MHNG 1089/12.

Spondylus avicularis Lamarck 1819
Probable holotype MHNG 1088/94 (figured herein, Plate 6,
Figs 26–28), figured by Chenu, pl. 5 fig. 4–4 a; locality on the
label: “Amérique”.
R e m a r k s : In the original volumes of Anim. Sans
Vert., an annotation by Rosalie de Lamarck states that
there was only 1 specimen in her father’s collection. In
the current Lamarck collection, MHNG 1088/94 was
the probable holotype, figured by Chenu, pl. 5 fig. 4–4 a.
According to G. Mermod, a former curator at the MHNG
(manuscript note with the specimen, dated 02.1947),
this specimen was formerly in the Delessert collection,
and labelled “Spondylus americanus Lk.”, together with
3 other shells. As the original type of Lamarck was not
found elsewhere, and as this specimen matches well the
description, Mermod recognised it as the probable type.
Lamy (1938: 277, 281) considered the species as a synonym of S. americanus.

17 specimens, all with “Océan Indien” or without locality indicated on the labels: MHNG 30784, 30785, 30786, 30787,

30797. MHNG 30796 (figured herein, Plate 7 Figs 32a, b) is a
right valve figured by Chenu on pl. 23 fig. 4 a. MHNG 30797 is
1 pv (figured herein, Plate 8 Figs 33–35) and was figured by
Chenu on pl. 23 fig. 3.
R e m a r k s : The specimen MHNG 1089/12 bears a
“18” handwritten annotation by Lamarck (now almost entirely faded) on the inner side of both valves. Lamy (1938:
192–193) stated that a specimen identified by Lamarck,

there was 1 specimen in her father’s collection. The
specimen currently in the Lamarck collection bears a

there was 1 specimen in her father’s collection. An
original handwritten label accompanies the specimen
1088/96 currently in the Lamarck collection. There is
no type locality indicated. A more recent label with the
specimen states “Amérique ?” as possible locality. Another specimen is also currently in the Lamarck collection: MHNG 1089/1; it bears a (faded) inscription (by
Lamarck ?) inside the valves (“species 11”), but it does
not seem to have type status, although it is undoubtedly
the shell figured by Chenu on pl. 15 fig. 2–2 a.
Extract from Lamprell, Stanisic & Clarkson, 2001:
“Spondylus coccineus Lamarck (non Schreibers 1793)
was briefly described by Lamarck (188, sp. 11), without
a stated locality. Examination of the Lamarck specimen
marked Spondylus coccineus in the MNHN showed a pearshaped spondylid with narrow, oblique auricles and densely
radially ribbed with ribs devoid of ornamentation probably
due to age and deterioration; internally off-white with a
raised crenulate, dark coloured margin. A specimen in the
MHNG is marked ‘Spondylus coccineus Lk. Type’ with the
locality ‘Amérique?’ (Chenu fig. 15/3), n° 11, registration
number MHNG1088/96. The specimen is ovate, with wide
interstices and strong, sparse spines on the 5 or 6 principal
ribs. The colour is tan-brown with a light orange coloured
internal crenulated margin. The specimen bears a strong
resemblance to Spondylus gilvus Reeve. Bernard, Cai &
Morton (1993) listed the species as occurring in China
without giving reference to which type specimen they based
their identification on, and gave the distribution as “Indian
Ocean, Philippines, South and East China to Okinawa”.
C u r r e n t t a x o n o m i c p o s i t i o n : Spondylus

there was 1 specimen of the main species in her father’s
collection, and 2 specimens of the variety [b]. For the
latter, Lamarck indicated also “Mus. n°”, which means
collection of the Paris Museum. An original handwritten label accompanies the specimen 1088/97 currently
in the Lamarck collection. A more recent label with the
specimen states “Oc. indien” as the locality. Lamy (1938:
293–296) placed S. costatus in synonymy with S. foliaceus Chemnitz, and recognized a type in the collection
of the Museum of Paris (see pp. 295– 296); it probably
refers to the variety b (then not a true type, according to
ICZN), as Lamarck stated that there were specimens of
the var. b in Paris Museum, but only 1 specimen of the
main variety in “his cabinet”, hence the status of probable holotype in MHNG.

on the label: “Oc. indien”. — D e l e s s e r t c o l l e c t i o n :
4 specimens; MHNG 31226: 1 specimen, figured by Chenu, pl.
29 fig. 1–1 a, locality “Oc. indien ou Amérique, Oc. Pacifique
?”; MHNG 31227: 1 specimen, figured by Chenu, pl. 6 fig.
3–3 a, locality “Colombie ?”; MHNG 31228: 1 specimen, figured by Chenu, pl. 11 fig. 3–3 a, locality “Mers de l’Inde, Oc.
indien ou Pacifique ?”; MHNG 31229: 1 specimen, figured by
Chenu, pl. 6 fig. 1–1 a, locality “Oc. Pacifique”.
there was 1 odd valve of the main species in her father’s
collection, and 1 specimen of the variety [b], although
for the latter, Lamarck indicated also “Mus. n°” (Paris
Museum). There is also a comment by G. Mermod accompanying this specimen, stating (free English translation from French) (March 10, 1947): “This specimen
does not bear any visible sign and is not accompanied by
any original label which would certify that it pertained to
the Lamarck original collection; but the fact that there is
only 1 odd valve, exactly matches the handwritten annotation by Rosalie de Lamarck in our copy of Anim. Sans
Vert., vol. 7 p. 191”. The specimen MHNG 1088/98 of
the Lamarck collection, figured by Chenu on pl. 11 fig.
4–4 a, and bearing a handwritten annotation by Lamarck
inside the valves, is likely the “type” of the var. b indicated by Rosalie de Lamarck, although it should be
noted that, according to the ICZN, an original specimen
of a variety has no actual type status.
According to Lamy (1938: 288), S. crassisquama is
a synonym of S. pictorum Chemnitz (= Spondylus foliaceus Schreibers 1793) (based on Chemnitz 1784: 85,
pl. 46 figs 472–473).

MHNG 1089/10 (figured herein, Plate 11 Figs 47–48), not figured in earlier literature, bearing handwritten inscriptions by
Lamarck inside the valves, and accompanied by a handwritten
label by Lamarck with the locality “Oc. indien ?”. This specimen
is a probable syntype (see remarks hereunder). — D e l e s s e r t
c o l l e c t i o n : 4 specimens, all with “Océan indien” as locality. MHNG 31231: 1 specimen (figured herein, Plate 11 Figs
49–50), figured by Chenu, pl. 27 fig. 1–1 a, locality on the label
“Oc. indien”; not figured material: MHNG 31232 (1 specimen),
MHNG 31233 (1 specimen), MHNG 31234 (1 specimen).
R e m a r k s : In the first edition of Anim. Sans Vert. (species # 17, vol. 6, p. 192), Rosalie de Lamarck (handwritten
annotation) indicated the presence of 1 specimen in the
personal collection of her father. Current specimen MHNG
1089/10 in the Lamarck collection bears handwritten annotations by Lamarck on the inner side of the valves, and
is accompanied by a handwritten label by Lamarck stating
“Spondylus croceus n. Chemn. 7 t. 45. f. 463”, Loc.: “Oc.
Indien ?”. It is probably the original specimen of Lamarck,
and thus probably a syntype, together with earlier Chemnitz’ specimens, as croceus is a validation of Chemnitz’
name (ICZN 72.4.4, 72.5.6, and 73.2.1; see also the discussion under Spondylus albus Chenu, another validation of an
earlier description by Chemnitz). The earlier non-binomial
description is by Chemnitz (Conchylien Cabinet, Vol. 7
(1784): 77, pl. 45 fig. 463).
However, one has to note that specimen MHNG
1089/10 does not match Lamarck’s illustration in the Encyclopédie Méthodique (pl. 191, fig. 4), as indicated by
Chenu (Illustr. Conchyl. text, p. 4). It is neither the specimen figured by Chenu on pl. 24 fig. 6, nor on pl. 27 fig.
1 (the latter being in the Delessert collection in MHNG).
Lamy (1938: 199–200) mentioned other shells labelled
“croceus” by Lamarck personally in the Paris Museum.

this specimen, stating (free English translation): “It is not the

MHNG 31241, 1 odd valve (not figured by Chenu), figured in

R e m a r k s : The MHNG should hold the type figured
by Chenu on his pl. 12 (see Chenu 1845: 5: “Collection
de M. Benj. Delessert”), but it is not currently in its collections. According to Lamy (: 299), it could be in the

R e m a r k s : It should be noted that only the lot
MHNG 31242 was labelled “TYPE” by G. Mermod.
However, as Chenu (: 5) did not explicitly indicate presence of a holotype, both specimens should be regarded
as syntypes, as both were original specimens figured by
him.

4–4 a and is 1 specimen of “var. b” (locality on the label: also
“Oc. Indien”). — Other material: 4 other lots were labeled
as “Spondylus muricatus Chemnitz”: MHNG 31512 (figured
herein, Plate 15 Figs 67–68): 1 specimen, figured by Chenu as
Spondylus ducalis on pl. 8 fig. 3–3 a, locality labelled “Amér.

MHNG 31513 (1 specimen), locality on the label “Oc. Indien”;
MHNG 31514 (1 spm), locality “Oc. Indien”; MHNG 31515
(1 empty box: specimen[s] missing), locality “Oc. Indien”.
Vert., there is an annotation by Rosalie de Lamarck stating that there were 6 specimens of the main species in her
father’s collection, plus 1 specimen of the “var. b”. An
old label with specimen MHNG 1089/7 states that this
var. b is a synonym of Spondylus lamarcki Chenu 1843
(see also Chenu: 6 and pl. 9, figs 3 & 4). Chenu figured
also S. ducalis on pl. 9 fig. 3–3 a; this specimen is in the
Lamarck collection, where it is now the type of Spondylus lamarcki Chenu 1843. In his text Chenu indicated
pl. 9 figs 3, 4 for S. lamarcki, but the caption for figs 3
& 4 on pl. 9 says “S. ducalis”. The specimen figured by
Chenu on pl. 8 fig. 3–3 a is in the Delessert collection
(MHNG 31512), but under the name S. muricatus Chemnitz (which is not a valid name). Other lots are registered
as “S. muricatus Chemnitz” in the Delessert collection of
the MHNG, but were not figured as such by Chenu: 4 lots
totalling 3 specimens, one box being empty, the specimens missing (see above, Delessert collection).

R e m a r k s : In the account of S. ducalis it was stated
that Chenu also figured the species on pl. 9 fig. 3–3 a.
The specimen corresponding to pl. 9 fig. 3 of Chenu is
in the Lamarck collection of the MHNG, under the name
Spondylus lamarckii Chenu, and labelled as a type of the
latter species (see also Chenu 1845: 6, text description
as S. lamarckii, although the plate caption mentions S.
ducalis). The specimen is registered as MHNG 1089/2.
Chenu figured another specimen (“variety b”) on pl.
9 fig. 4–4 a, which could not be traced among the material in MHNG. In the Lamarck collection is another
specimen (MHNG 1089/7) which has some strong affinities with the shell figured by Chenu on pl. 9 fig. 4–
4 a, but showing also some features that allow us to say
that it is not the very same specimen as the one figured.
This specimen is labelled as “variety b of ducalis (= S.
lamarckii Chenu, = latreillei Chenu)”.

R e m a r k s : The possible type MHNG 1088/100 bears
a handwritten annotation, possibly by Lamarck, on the
inner side of the valves (“N° 8”). In the original volumes of Anim. Sans Vert., an annotation by Rosalie de
Lamarck states that there was 1 specimen of the species
in her father’s collection. This MHNG 1088/100 specimen was figured by Chenu on pl. 13 fig. 1–1 a. However, it does not seem to match (pattern of distribution of
spines, etc.) the original illustration by Lamarck (Encyclopédie Méthodique: pl. 194 fig. 2), which is the reason
why it is considered as a questionable type. Lamy (1938:
277, 282) already considered S. longispina as a synonym
of S. americanus.

94–96), figured by Chenu, pl. 9 fig. 2–2 a; locality on the label:
“Amér.”.
there was only 1 specimen in her father’s collection.
In the Lamarck collection, MHNG 1089/8 is the probable holotype (figured by Chenu on pl. 9 fig. 1–1 a),
with a handwritten annotation “15” on the inner side of
the valves. Another specimen currently in the Lamarck
collection, MHNG 1088/93, is the specimen figured by
Chenu on pl. 9 fig. 2–2 a, and actually labelled from the
“Delessert collection”. Mermod, in his manuscript index
card file for the Lamarck collection, states that the type
is the specimen illustrated by Chenu on pl. 9 fig. 1–1 a
(MHNG 1089/8, see above). But it remains difficult to
prove which of the two specimens figured by Chenu
is the real type. Specimen 1089/8 appears most likely,
because of the presence of the handwritten annotation
“15” inside the valves. Unfortunately, Lamarck did not
indicate a size for the species in his description. The
uncertainty is also increased by Lamarck’s indication
“cabinet de M. Dufresne”, which means that there is also
a possibility that neither of the two specimens figured by
Chenu could be type material. The statement by Lamy
(1938: 287) that S. longitudinalis could be a synonym of
S. gaederopus most likely should be discounted (see also
Fulton 1915: 360).

questionable type MHNG 1089/9 (figured herein, Plate 21 Figs

there was 1 specimen of the species in her father’s collection. In the Lamarck collection, specimen MHNG
1089/9 has no visible indication by Lamarck on the inner side of the valves. Lamarck did not figure it, nor is
there any illustration of S. microlepos by Chenu in his
Illustrations Conchyliologiques. It is thus very hard to
say whether the specimen in the Lamarck collection of
the MHNG is the original specimen or not. An extract
from Lamprell & Healy (2001) states: “Inspection of a
specimen in the Muséum de Genève (1089/9) labelled
as ‘Spondylus microlepos Lk. TYPE ?? (coccineus var.)
Chine?’ revealed a yellow-orange shell with numerous
ribs. In all respects, the features of this shell are hard to
reconcile with the description given by Lamarck (p. 190,
sp. 16): Sp. testâ utrinque rubrâ, longitudinaliter striatâ
et costatâ; costis 5 s. 6 squamiferis: squamis ligulatis
truncatis exiguis”. Consequently, with only 1 specimen
of very questionable status labeled “microlepos” in the
Lamarck collection, with a text description by Lamarck
in Anim. Sans Vert. that could apply to many different
species of Spondylus, and with no original illustration
available, nor any old subsequent illustration by Chenu
either, the species microlepos must be considered a nomen dubium.

locality on the label: “Oc. indien ?”.
R e m a r k s : Lamy (1938: 285, 286, 293, 295) recognized the distinction between the S. multilamellatus of
Lamarck and the S. multilamellatus of Chenu. Lamarck
describes a white species “flowered” with pink and purple
streaks, while Chenu’s specimens are brown. In the original volumes of Anim. Sans Vert., Rosalie de Lamarck
made no handwritten annotation for S. multilamellatus
Lamarck, meaning that there was no material in her
father’s personal collection. Lamarck says “Mus. n°”(=
MNHN, Paris), instead of “Mon cabinet”. But Lamy
(1938: 295) also says that the type of S. multilamellatus
Lamarck could not be retrieved in the Museum of Paris.
Together with the specimen MHNG 31508 cited here
above, there is a note by G. Mermod saying (free English
translation) that “According to Lamy (1938: 285, 286),
Fulton (1915) identifies the S. multilamellatus of Chenu
as S. ictericus of Reeve”. But, still according to Mermod,
“the comparison with our specimens leads to the conclusion that this supposed synonymy is erroneous”. S. multilamellatus of Lamarck is the S. foliaceus of Chemnitz
(see Lamy, 1938: 293, 295); but there is no manuscript
note by Mermod about this. The present authors agree
with Fulton that the Chenu figure agrees well with the
type of S. ictericus Reeve.

note by G. Mermod with this specimen, stating [free English
translation]: “this specimen seems to come from Mauritius, but
its resemblance to the specimen figured by Chenu, pl. 28 fig. 3,

Vert., Rosalie de Lamarck indicated the presence of two
specimens in her father’s collection. Among the three specimens in the Delessert collection, two are undoubtedly those
figured by Chenu, but it is hard to say whether one of them
is also that figured by Lamarck in the Encyclopédie Méthodique, pl. 191 fig. 5; the closest would probably be specimen MHNG 31526, figured by Chenu on pl. 8, fig. 2.

Delessert 1841, pl. 20 fig. 2, and by Chenu, pl. 7 fig. 2; locality
on the label: “Océan indien”; MHNG 1089/17 (figured herein,

collection, figured by Lamarck, Encyclopédie Méthodique, pl.
193 fig. 1, and by Delessert 1841, pl. 20 fig. 1, as well as by
Chenu, pl. 7 fig. 1; locality on the label: “Océan indien”.
Vert., Rosalie de Lamarck made no handwritten an-
notation for S. regius Lamarck, meaning that there was
no material in her father’s personal collection. There
is no type material in the collection of the MHNG, but
the famous specimen bought by Richard (on which he
sat down, breaking 1 or 2 spines, after his wife discovered that he sold her silver-ware to get the money to
buy that shell ...) is in the MHNG collection. This specimen from the Richard cabinet was later included in
the Lamarck/Delessert collection and is now registered
MHNG 1089/17 (see Dance, 1986: 98–99; also Cailliez & Finet, 1997: 17). Lamarck, in the Encyclopédie
Méthodique on pl. 193 fig. 1, figured the specimen. But
it was more faithfully figured with its broken spines by
Chenu, pl. 7 fig. 1.

“Oc. indien”.
R e m a r k s : According to Lamy (1938: 202), the
specimen (MHNG 31648) figured by Chenu cannot be
a S. violacescens of Lamarck 1819. The collections of
the MHNG do not contain any material of the true violacescens of Lamarck, for which, in the original volumes
of Anim. Sans Vert., Rosalie de Lamarck did not mention the presence of any specimen in her father’s collection. Lamarck indicated only “Mus. n°” (= MNHN,
Paris), and Lamy (1938: 202) recognises a specimen of
37 mm in the MNHN (Paris) as the type of violacescens
Lamarck.

Acknowledgment
The first author (Y. Finet) is very grateful to the Society of
Friends of the Museum of Natural History of Geneva for the
financial support having made possible the publication in color
of most specimens and types from the Lamarck and Delessert
(types of Chenu) collections of the Geneva Museum. Many of
these Spondylid specimens were illustrated in color by Chenu
in his “Illustrations Conchyliologiques”, but it’s valuable information to see this material, and more, now figured using color
photographs for the first time.
