Blonogrcq-jh of the Families Neritidce, Neritopsidce, 
Adeorbiidcb, Cydostrematidce, and Liotiidce. 


Animal with a broad, short muzzle, and long slender tentacles, 
with eyes on jDromineut pedicels at their outer bases, foot oblong, 
wide in front, attenuated behind, branchia long, triangular, pointed, 
free at its extremity, ventricle embracing the intestine, anus on the 
right side. 

Dentition : 8-I-(3 -+ I + 3)-I-8. The middle tooth- small, sub- 
quadrangular, second central tooth very large, transverse, sub- 
rhomboidal, third and fourth central teeth very small ; lateral tooth 
with reflected, simple or denticulated margin ; marginal teeth nu- 
merous, narrow, curved, serrated. PI. 1, figs. 2, 3. 

Shell imperforate, thick, semiglobose, porcellanous, spire very 
small, internally porcellanous, the cavity simple from the absorjD- 
tion of the internal portion of the whorls by the animal (PI. 1, fig, 
15), aperture semilunate, entire, the columellar lip flattened, septi- 
form, with a rectilinear, plain or dentate margin, outer lij) rounded, 
sharp or thickened, not reflected. 

The impression of the adductor muscle is horse-shoe shaped, open 
in front, and is visible within the ajoerture. 

Operculum calcareous, usually subspiral, provided with projecting 
lobes on its inner face, the inner margin forming a pseudo-articula- 
tion with the columellar lip. 

Aquatic, although some species can live out of water ; herbivor- 

The Neritidse have been monographed by: 

Reeve, Conch. Icon., ix, 1855. 

Sowerby, Thes. Conch, ii, and v. 

Von Martens, Kiister's Conchylien Cabinet, 1879, 1881, 1887. 

The latter author has given for this family the most comj^lete and 
carefully worked-up generic monographs that have lately appeared 



in either of the iconographies. I have, in the main, followed his 
arrangement of the species, although a different disposition of some 
of the groups has ap})eared to me more desirable, and has accord- 
ingly been attempted. In the Neritinse Von Martens has made the 
opercular processes the l^asis of his classification, whilst I have con- 
sidered characters of the shell as of more importance ; the result is 
a different succession of groups, whilst their contents remain es- 
pentially alike. 

Synopsis of Genera. 
Genus Is^ERITA, Adanson. 1757. 

Shell thick, smooth or spirally ridged and grooved, porcellanous, 
under a corneous adhering epidermis — sometimes wanting ; outer 
lip thick, usually denticulated within, columellar lip flattened, its 
margin dentate, straight. Operculum calcareous, the outer face 
granulated or with a decurrent groove, paucispiral, with excentric 
nucleus, inner fjice callous, the apical and claviform apophyses well- 
marked, marginal apojDhysis more or less developed, corresponding 
with the groove of the outer face. 

Animal usuall}' with festooned mantle margin. Living on rocks 
and stones, generally inactive by day, but said to be active at night, 
roaming about and feeding on algse, etc. Gregarious, and littoral, 
and nearly exclusivel}^ marine. 

About 200 living species have heretofore been recognized, in- 
habiting tropical and semitropical shores throughout the world. 
Sixty fossil species have been enumerated, but the earlier forms are 
somewhat doubtful, and may more probably be referred to Nerito- 
Section Nerita, Lamarck. 1799 (sensu stricto). 

Columellar lip granular or tuberculated. N^. albicilla, Linn. 

Theliostyla, Morch. 1852, and Natere, Gray. 1858, are synonyms. 
Section Peloronta, Oken. 1815. 

Columellar lip nearly smooth, its margin strongly dentate, outer 
lip dentate within. N. peloronta, Linn. 

Tenare, Gray. 1858, is a synonym. 
Section Pila, Klein. 1753. 

Columellar lip rugosely grooved and ridged, its edge dentate, 
outer lip plicate Avithin, with a large tooth at either extremity of the 
series. N. plicata, Linn. 
• Ritena, Gray. 1858, is a synonym. 


Section Odontostoma (Klein, 1753), Morch. 1852, 

Columellar lij^ smooth or nearly smooth, its margin dentate, outer 
lip scarcely denticulated within. N, polita, Linn. 

Subgenus Lissochilus, Petho. 1882. 

Inner lip smooth, its margin not dentate, outer lip sharp, not 
thickened or dentate within. Triassic and Jurassic. 


Subgenus Otostoma, d'Archiac. 1859. 

Shell with longitudinal plications and very fine spiral lines, col- 
umellar lip thick, with dentate margin. 

Cretaceous of Europe, Algiers and Asia Minor. N. rugosa, 

These fossils have usually lost the columellar lip and the inner 
layer of the outer lip, but traces of these destroyed parts are found 
upon casts. The discovery of a silicified specimen in good preser- 
vation and intact has proven the identity of Otostoma with Nerita ; 
its longitudinal plications will serve to distinguish it subgenerically, 

Lyosoma, White. 1882, appears to be synonymous. Its type is 
L. PowELLi, White, from the Jurassic of Utah. 

Genus DESHAYESIA, Raulin. 1844 

Shell subglobose, thick, umbilicated, spire short ; aperture entire, 
semicircular, oblique, columella convex, denticulated, outer lip 
smooth internally. 

Eocene and Miocene ; Paris and Bordeaux basins. 
D. Neritoides, Grat. Struct, and Syst. Conch, PI. 78, f. 59. 

This genus presents a very remarkable combination of the char- 
acters of Nerita and Natica, and appears to establish a passage be- 
tween those genera. 

Genus NERITINA, Lam. 1809. 

Shell imperforate, rather thin, globose, with short spire, usually 
smooth, columellar lip flattened, smooth, straiglit-raargined, finely 
denticulated or smooth, outer lip sharp, not callously thickened or 
toothed within, aperture with a projection on the inner surface near 
the base of the columella (PI. 1, fig. 16). 

Operculum calcareous, completely closing the aperture ; exteri- 
orly paucispiral with excentric nucleus, interiorly with an apical 


and a claviform apophysis, both arising from the summit, and some- 
times a medio-margiual apophysis in addition, arising from the 
columellar or inner margin (PI. 1, figs. 9, 10). 

No important differences in the soft parts have been detected be- 
tween Nerita and Neritina. Dentition, PI. 1, fig. 3. 

About 200 generally recognized species have been described. 
They are mostly fluviatile, but a few inhabit marine or brackish 
water, and a very few are of terrestrial habitat. They are mostly 
tropical and subtropical in distribution. Fossil, they occur from 
the liassic downwards, the pattern of coloring being well preserved ; 
the genus becomes numerous in species in the miocene and pliocene. 

The Neritin^e are small, smooth, globular shells, ornamented with 
a great variety of black or purple lines, bands or spots, covered by 
a smooth, polished, horny epidermis. Some species are amphibious, 
clinging to the roots of Nipah palms and other trees on the mar- 
gins of rivers, while a few inhabit the foliage of tall trees that over- 
hang the water. 

Neritella (Humphrey. 1797), Gray. 1847, Lamprostoma, Swains. 
1840, and Neritcea, Roth, are synonyms. 

Section Nekitina (seusu stricto), Swainson. 1840. 

Lip sharp, columellar lip rather convex, with crenellated margin, 
parietal ridge well marked, dentiform, form ovoid with rather high 
spire, usually strigate. Operculum reddish or blackish, both pro- 
cesses well developed, separate. Fluviatile. N. zigzag, Lam. 

Section Puperita, Gray. 1857. 

Shell white, with black zigzag strigations, yellowish within. 
Similar to the above, but marine. N. pupa, Linn. 

Section Neeitodryas, Martens. 1869. 

Columellar margin smooth. Rib of the operculum deeply furrowed, 
multilobate at the tip, deeply excavated beneath. Terrestrial. 
N. CORNEA, Linn. 

Inhabit damp foliage, Philippines, etc. 

Section Theodoxus, Montf. 1810. 

Transversely globose, smooth or nearly smooth, columellar mar- 
gin smooth. The claviform apophysis of the operculum distinct, 
the apical apophysis rudimentary. Fluviatile. Inhabits mostly 
rivers of Europe and Western Asia. 


Neritoglobus, Kobelt. 1871, Elea, Ziegler. 1833, and Neritoconus, 
Kobelt. 1871, are synonyms, N. fluviatilis, Linn. 

Kobelt separates the species into two subsections, according to the 
globose or conical shape of the shell, but the latter form represents 
an abnormal growth, including specimens of species undoubtedly 
belonging normally to the former. 

Section Neritodonta, Brusina. 1884. 

Columella thickened, callous, columellar margin subdenticulated ; 
parietal apophysis projecting. N. Lukovici, Brusina. Tertiary 
of Dalmatia. The genera (!) Tripaloia, Letourn., and . Calvertia, 
Saint-Slmonia, Petrettinia and Burgersteinia, Bourg., are identical. 

Section Neritilia, Martens. 1879. 

Columella smooth ; operculum with a single erect spatulate pro- 
cess. N. succiNEA, Recluz. Guadeloupe, W. I. 
Section Smaragdia, Issel. 1869.

liquely oval, with short spire ; columellar area callous, the margin 
finely denticulate. N. viridis, Linn. Marine. 

West Indies, Mediterranean, Pacifie. 

Gaillardotia, Bourg. 1876, is a synonym. 

Section StAnleya, Bourg. 1885. 

Brilliantly polished, transparent, spirally sulcate, imperforate, 
with large parietal callus, 3 sp. Lake Tanganyika. N. neki- 
TOiDES, Smith. 

Section Clypeolum, Recluz. 1850. 

Shell globular, oval or conic, covered by a corneous epidermis, 
columellar margin not dentate, outer lip prolonged upward on the 
spire in a tongue-like manner. Operculum colored, with well de- 
veloped apophyses, the claviform apophysis grooved. Fluviatile. 
Indo-Pacijic. N. pulligera, Linn. 

Section Neritona, Martens. 1869. 

Oval globular, with very short spire ; peritreme widely developed, 
subcontinuous, columellar margin not denticulate. Operculum with 
the apical process depressed, flattened, lobate at the tip. Fluviatile. 
N. labiosa, Sowb. 

Subgenus Clithon, Montfort. 1810. 

Shell coronated with tubercles, or short or long spines (sometimes 
unarmed), and covered by a corneous epidermis ; margin of colum 


ellar lip usually finely denticulated, often with a large sujDerior 
tooth. Operculum with rib and apophyses well developed, the 
latter connected for half their length. 

The spines that usually ornament the whorls are tubular, and 
sometimes very long. They are fluviatile and tropical, crawling 
slowly, and only showing during locomotion the tentacles and tip of 
the muzzle ; they seem to prefer a stony bottom, clear and free from 
weeds, and quiet Avater. N. longispina, Recluz, 

Subgenus Neriptekon, Lesson. 1830. 

Shell flattened, biauriculated posteriorly, spire posterolateral ; 
inner lip septiform, with non-denticulated margin, outer lij^ very 
much dilated behind. Operculum typical. Fluviatile. Polynesia. 
N. Tahitensis, Lesson. 

Section Alixa, Recluz. 1842. 

Shell flattened, transversely dilated, lip irregularly expanded, 
sinuous, margin of inner lip finely denticulated. Operculum typi- 
cal. Fluviatile. Central America. JST. latissima, Brod. 

Subgenus Dostia, Gray. 1840. 

Shell sandal-shaped, solid, the apex completely posterior and a 
little lateral ; peristome continuous and free ; inner lip septiform, 
arcuated and denticulated in the centre of its margin. Operculum 
typical. Brackish water. Indies. N. crepidularia. Lam. 

Genus VELATES, Montfort. 1810. 

Oval conic, spiral at the apex only ; last whorl greatly enlarged, 
resembling Trochita externally ; aperture basal, semicircular, its 
margin forming with that of the wide, flat columellar lip a circular 
outline, columellar margin dentate. Operculum as in Neritina. 

Tertiary of Europe, India, Madagascar, etc. V. perversa, 
Linn. (Struct, and Syst. Conch., t. 78, figs. 81, 82). 

Young individuals are Neritiniform, and the apex is completely 

Section Velatella, Meek. 1878. 

Shell small, oval; apex posterior, spiral, dextral, submedian. 
V. CARDiToiDES, Meek (Struct, and Syst. Conch., t. 78, figs. 85, 86). 
Laramie formation, N. America. 


Subgenus Tomostoma, Desh. 1823. 

Shell oval, apex slightly spiral, iuclined posteriorly, base I'ounded. 
PiLEOLus NERiTOiDES, Desh. Eocene, Europe. 

Calana, Gray, 1844, is a synonym. 

This group, resembling the recent Navicellie, has been referred 
by myself and others to Pileolus. 

Genus NERITOMA, Morris. 1849. 

Shell ventricose, thick, apex eroded ; aperture with a notch in 
the middle of the outer lip, inner lij^ excavated in the middle, 
without teeth. Jurassic, Europe. N. angulata, Sowb. (Struct, 
and Syst. Conch., t. 78, fig. 63). 

Casts of this shell are common, and exhibit the interior charac- 
teristic of the Nerites: — it was probably fluviatile. 

Subgenus Neridomus, Morris and Lycett. 1850. 

Smooth, ovately globose, spire small, oblique ; last whorl very 
large ; aperture ovate or semilunar, outer lip thick, inner lip con- 
vex, smooth. Great Oolite, England. N. hemisph.erica, Romer. 
(Struct, and Syst. Conch., t. 78, f. 64). 

Subgenus Oncochilus, Petho. 1882. 

Shell smooth, columellar area covered by a swollen, thick callos- 
ity, the margin smooth or with two or three small teeth ; outer lip 
sharp, smooth within. Triassic, Jurassic. N. globulosus, Klip- 

Genus DEJAXIRA, Stoliczka. 1860. 

Shell subglobose, consisting of a few whorls, the last one large, 
spirally grooved, often carinated posteriorly ; aperture large, sub- 
trigonal or oval-elongated, columellar lip callous, having three large 
plications, outer lip sharp. Operculum calcareous, inner margin 
sinuous, with groove corresponding with columellar plication, inner 
face with an obtuse claviform apophysis. 

Lacustrine Cretaceous of Europe. D. bicarinata, Stol. (Struct. 
and Syst. Conch., t. 78, figs. 57, 58). 

Leymeria, Munier-Chalmas. 1884, is a synonym. 

Genus NAVICELLA, Lamark. 1809. 

Shell imperforate, oblong, smooth, limpet-like with a posterior, 
submarginal apex, clothed with a corneous epidermis, often eroded 


at the apex ; aperture large, basal, with a small, not dentate col- 
umellar shelf, and elongated lateral muscular scars. Operculum 
much smaller than the aperture, irregularly subtetragonal ; labral 
margin subcai'tilaginous ; coluniellar margin sinuous, partly bor- 
dered by a parietal apophysis, projecting at its extremity ; apex 
vermicularly granulated on the inner face, with a few radiating 
strijB on both fiices (PI. 1, figs. 11, 12). 

Head large, eyes on long peduncles, foot large, regularly oval, 
attached on each side to the visceral mass, forming a cavity open 
behind, in which the operculum is j^artly buried. Dentition, PI. 1, 
fig. 2. 

The species, about fifty in number, are exclusively East Indian 
and Polynesian in distribution. They are usually found on the 
banks of rivers adhering to floating sticks and to the petioles and 
roots of the Nipah palms and other plants that live near the water ; 
they are also found attached to smooth stones. 

The synonymy includes Septaria, Fer. 1807, which has priority, 
but has not usually found accejitance, Catillus (Humphrey. 1797), 
Swainson. 1840. 

Section Cimber, Montf 1810. 

Apex median, usually decorticated, projecting beyond the posterior 
margin. N. porcellana, Linn. 

Dr. Gray has characterized three sections of this group, under 
the names of Laodia, Elana, and Paria, all in 1867: they are dis- 
tinguished partly from the opercula, partly from the shells. The 
former are so variable in their characters that they aflford but 
slender material for systematic purposes. The following may per- 
haps be maintained : 

Subsection Paria, Gray. 1867. 

Septum projecting, and truncated in the middle. N. Freycineti, 

Section Stenopoma, Gray. 1867. 

Apex median, posterior, submarginal, entire; shell generally 
narrow. N. lineata, Lam. 

Section Elara, H. and A. Adams. 1854. 

Apex a little elevated above the posterior margin and laterally 
recurved. N. Lapeyrousei, Recluz. 

To these Gray adds a group Orthopoma, 1867, characterized by 
an operculum only, the shell of which is unknown. 


Genus PILEOLUS (Cookson), Sowerby. 1823. 

Shell limpet-like, solid, circular or elliptical at the base, convex, 
with subcentral, non-spiral apex; a])erture small, semilunar; col- 
umellar septum convex, smooth or toothed, peritreme continuous. 
Operculum unknown. Fossil; Jurassic to Cretaceous. P. plica- 
Tus, Sowb. 

Subgenus Gargania, Guiscardi. 1856. 

Apex elevated, inclined backwards beyond the peritreme, surface 
radiately ribbed ; lij^ with a central, internal depression. Creta- 
ceous. G. Brocchii, Guiscardi. 


Shell discoidal, few whorled, longitudinally grooved at the back, 
and slightly rugose with growth-lines ; dextral side convex, deeply 
and narrowly perforated, sinistral side flat, exposing the inner 
whorls. Operculum calcareous, solid, sinistrally subspiral, with 
two internal apophyses, one of them beneath the nucleus, very thick 
and rugose. 

Genus MACLUREA, Lesueur, em. 1818. 

The characters are those of the family, of which this is the sole 
genus. A dozen palaeozoic sj)ecies from North America and Scotland 
have been described. M. Logani, Salter. (Struct, and Syst. Conch., 
t. 82, f. 8, 9) ; M. magna, Lesueur. (Ibid, t. 65, f. 10). 

Conchologists have been at a loss where to place this singular 
genus ; according to some it has been included in Solariidse ; others 
have placed it in Pleurotomariidse and in Atlantidi?e. In my "Struc- 
tural and Systematic Conchology" I have given it a position be- 
tween Bellerophontidie and Haliotidie. I think that Dr. Fischer's 
removal of the group to the vicinity of Neritidte, on account of the 
apophyses of the operculum, is a happy idea of that learned con- 



Animal with large head, and distant, elongated tentacles, the 
gyes on short peduncles at the exterior base, buccal orifice plicate, 
foot obtuse at either extremity, operculigerous disk surrounding the 
operculum, columellar muscle forming a ring interrupted above, 
mantle-margin thickened and papillary. Dentition, 8'l'(2-)-0+2)"l*8, 
PL 1, fig. 1. 

Shell imperforate, neritiform, solid, columellar lip not dentate, the 
margin with a sinus in the middle. Operculum thick, calcareous, 
symmetrical, not spiral, with lateral, median nucleus, the exterior 
face convex, the interior face divided into two unequal parts, the 
columellar margin with a median appendage. 

Fossil oi^ercula of this family, occurring frequently without the 
shell, were long objects of doubt to scientists, and have received the 
names of Peltarion, Deslongchamps. 1858 (PI. 1, figs. 5, 6), Sca- 
phanidea and Cydidea, Rolle. 1862, and Hypodevia, Koninck. lo53. 
They have been supposed to be the beak of a cephalojiod, a valve 
of a brachiopod or of a chiton, and an operculum of the polyp 

Genus NERITOPSIS, Grateloup. 1832. 

General characters those of the family. Shell white, cancellated 
by spiral and longitudinal ridges and striae. Operculum having on 
its exterior face and columellar margin a large truncate appendage, 
interior face depressed, with a labral, semilunar, smooth part, and 
a striate columellar part, with a pit on either side of it. (PI. 1, figs. 
7, 8). Radula, Gray, 1840, is a synonym. East Indies, Polynesia. 
N. RADULA is the only recent species. Fossil, secondary and ter- 

Genus NATICOPSIS, M'Coy. 1844. 

Shell imperforate, naticiform, thick, suture plicate; columella 
callous, more or less flattened, sometimes minutely tuberculated or 
transversely plicate, lip sharp ( F*l. 1, fig. 17). Operculum something 
like Neritopsis, with convex exterior face, the interior face un- 
equally two-parted, one part smooth, the other rugose, no appen- 
dage on the columellar margin (PI. 1, figs. 13, 14). 

Europe, India. 

I included this group in Naticidee (Vol. viii, 8) ; the oi^erculum, 
however, shows it to be a member of the present group. Nerito- 
mopsis, Waagen. 1880, Carboniferous of India, is a synonym. 


Subgenus Trachydomia, Meek and Wortheu. 1866. 

Whorls regularly ornamented with small tubercles. N. nodosa, 
Meek and AVorthen. Carboniferous. Illinois. 

Included in Naticidse (vol. viii, 8), but is better j^laced here 


Shell umbilicated, auriform, depressed, paucis2:)iral, with oblique, 
entire aperture, simple columella, and rounded, sharp outer lip. 
Oj^erculum corneous, paucispiral, with excentric nucleus. 

Animal differing from Trochidse by having no cirriform appen- 
dages of the foot. Dentition unknown. 

In this group are provisionally included a few small shells, the 
relationships of which remain somewhat obscure. 

Genus ADEORBIS, S. Wood. 1842.

Scarcely unibilicated, aperture circular, surface spirally costate, 
not cancellated. A. granulum, Brugn. Mediterranean. 



Animal with ciliated, thread-like tentacles, the eyes on short pe- 
duncles ; snout bilobed ; foot elongated, truncate in front, and ex- 
tending at each angle into a filament ; sides with three or four pairs 
of ciliated cirri, and a pair of auricular appendages in front, be- 
tween the cirri and the tentacles. Jaws scaly. 
Dentition, 8-(4 + 1+ 4)-8, PI. 1, fig. 4. 

Shell small, umbilicated, depressed, white, corneous or transpar- 
ent, not nacreous ; aperture circular, with continuous, sharp peris- 
tome. Operculum corneous, multisjiiral. 

Genus CYCLOSTKEMA, Marryatt. 1818. 

Shell white, or uniformly colored, last whorl obliquely striate. 
C. CANCELLATA, Marryatt. 

About 25 species have been described ; distribution nearly uni-

Genus VITRINELLA, C. B. Adams. 1850. 

Shell minute, depressed turbiniform, white, often -with spiral 
cariniB, widely umbilicated, and the umbilical region widely indented, 
whorls few, aperture large, rounded. Operculum unknown. 

V. VALVATOiDES, C. B. Ad. A considerable number of species 
have been described by Prof. Adams from Jamaica and Panama. 
They ai'e mostly unfigured, and Dr. Fischer thinks that species of 
Cyclostrema, Adeorbis, Teinostoma and Pseudorotella are included. 

Genus Teinostoma, H. and A. Adams. 1853. 

Shell orbicular, depressed, polished or spirally striated, spire

Family NERITIDjE. 

Geuus NERITA, Adanson. 1757. 

Dr. vou Martens, in the prefoceto his monograph of Nerita, now 
in course of publication, thus divides the geuus into groups, which 
he considers " more or less natural," whilst not so sharply distin- 
guished one from another as the similar divisions of Neritina. I 
find the older and more simple divisions W'hich I have adopted full 
of difficulties to the systematist, which Avould be much increased by 
a more elaborate system. It is noticeable that Dr. von Martens 
has not arranged his own monograph by the system he proposes. 
His groups are : — 

1. Theliostyla, Morch. Whorls flattened, strongly ribbed, 
columellar area granular, the marginal teeth mostly small. Oper- 
culum granular. N. textilis. Natere, Gray, is a synonym. 

2. Cymostyla, Martens. With weaker spiral ribs, whorls 
rounder, columellar area with parallel plications, the teeth stronger. 
Operculum granular. N. undata. Plia, Mtirch, in part, but not 
Pila, Klein. 

3. Pila, Klein. Shell bullet-shaped, with strong rounded spiral 
ribs, and strong columellar teeth. Operculum concave, weakly 
granular or smooth. N. plicata. Ritena, Gray, and Tenare, 
Troschel (not Gray), are synonyms. 

4. Tenare, Gray. Teeth of the interior of the outer liji vanish- 
ing. Oper(ailum smooth, with polished marginal zone. / 

a. Peloronta, Troschel. With weak spiral ribs. Marginal 
zone of the operculum swollen, distinct. N. peloronta. 

h. Ilynerita, Martens. Spiral sculpture stronger, teeth of the 
mouth weaker. Operculum with scarcely developed marginal zone. 


5. Nerita (restricted). Spiral sculpture weak or Avanting, colum- 
ellar area swollen, smooth. Operculum flat, with ribbed margin. 
N. POLiTA. Odontostoma, Morch (in part), is a synonym, 

6. Amphinerita, Martens. Shell as in preceding group. OjDer- 
culum granular. N. Umlaasiana, N. Senegalensis, etc. 

7. Heminerita, Martens. Outer lip not toothed, columellar 
margin likewise toothless. Operculum with strongly developed 
skinny projection on its convex margin. N. pica. This group is 
the most nearly related to Neritina.

however, all shown not infrequently by occasional West Indian

Sometimes the ribs are more numerous by their division, and by 
the interpolation of smaller intermediate ones. The species is al§o 
subject to erosion in such manner that the black markings become 
elevated and the ribs obliterated, in this condition becoming ^•

black margined, with rather strong internal plicate teeth, columellar 
area smooth, the margin minutely toothed in the middle.

Australia, New Zealand, etc. 

Reeve figured this species for the N. atrata, Chemnitz — which it 
probably is not, and on this account von Martens preferred for it 
the name N. jmndata. Quo}' — which it ertainly is not, whilst 
Hutton imposed the name of X. saturata, and E. A. Smith that of 
N. melanotragus, both in 1884, with a probable priority of publica- 
tion of the former name. "NVatson (Voy. Challenger, xv, 132) reviews 
the whole subject, preferring the name N. punctata. Inasmuch as 
Chemnitz was not binomial and therefore not entitled to quotation, 
and his figures and description are neither of them sufficient for 
identification, whilst they indicate that at least two species were 
confounded by him, I think it preferable to treat him as non-existent, 
and quote Reeve ; especially as he has been followed by others, so 
that his atrata has become well-known. N. nigra, Gray (who quotes 
Quoy) in "Dieflenbach's New Zealand" has been cited by authors as 
applying to the present species, but the name is not accepted by 
them on account of the prior N. nigra, Chemn. They show that 
Quoy never described a N. nigra, but then neither did Gray; he 
merely mentioned the name in his above list, and it is impossible to 
determine what species he may have intended. Finally, different 
as this species is from N. nigerrima, Chemn., in its form and absence 
of columellar granulations— actually a group distinction, I have never- 
theless some suspicion that it is only a variety of it, and that it 
connects that species with N. morio, which, on account of its smooth 
inner surface of the lip belongs to still another group. In my 
saner moments I am well-aware that such vagaries of conjecture 
are simply the demoralizing result of the questionable questioning 
which has largely supplanted the questionless faith of the last 
generation of conchologists.

The above may be regarded as the typical system of coloration 
in a species varying much in this respect. It has, under different 
aspects received a number of names, several of which I retain as 
varietal, not so much because of intrinsic value as for mere con- 
venience, these several forms having been heretofore recognized as 
species. With the type may be included N. Papnuina, Recluz, N. 
LeGuillouana, Recluz (fig. 87), N. marmorata, Hombr. et Jacq., 
N. Savieana, Recluz, (fig. 88), N. crassa, Gould (fig. >*9), N. undulata, 
Gmel. and N. Novce-Guinece, Lesson (fig. 90), the two last juveniles. 

Var. MicRONEsrCA, Martens. 

Blackish olivaceous, with two spiral black bands. 

Var. STRIATA, Burrow. Figs. 91-94, 100, 1. 

Costulations small, close, somewhat unequal, greyish, yellowish, 
or light brownish, usually spotted, undately strigate or trifasciate 
with dark grey, olivaceous or black, aperture tinged with yellow. 

The synonyms are N. chrysostoma, Recluz (in part, fig. 91), N. 
undata, Gould, Var. icterina, Marts, including N. aurantia, Recluz, 
(fig. 92), iV. Tongaensis, Hombr. et Jacq. N. grisea. Reeve (fig. 93), 


N. erubescens, Reeve (fig. 100), N. Neritopsoides, Reeve (fig. 1), 
and N. costulata, Biisch and i\". Essingto)ii, Reeve (fig. 94), the two 
latter juveniles. 

Var. Spengleeiana, Recluz. PI. 6, figs. 96-98. 

Greyish, maculated Avith white, interruptedly trifasciate with 
greyish black, riblets flattened, obscure, evanescent below, aperture 

The type was a juvenile; and iV. oleagina, Reeve (figs. 96, 97) 
is a synonym. 

Var. QUADBicoLOR, Gmelin. Fig. 86. 

Whitish, yellowish white or rosy white, the ribs maculated with 
purplish black, aperture white. 

Red Sea, Bombay, E. coast of Africa, Southward to Natal. 

It is N. maris-rubrce, Chemnitz. 

Var. INCURVA, Martens. Fig. 99. 

Variegated and interruptedly banded with black and yellowish 
grey, aperture white tinged with yellow or fulvous, the outer margin 
elongated and sinuated at the extremities, above and below; riblets 
about 30, flat, close, nnequal. Diam. 30-39 mill. 

Mozambique, E. Africa. 

Var. Grayana, Recluz. Figs. 2, 3. 

Riblets rather narrow and high, sometimes with intermediate 
smaller ones, jnirplish, varying to ash grey, somewhat obscurely 
maculated with purplish black or darker grey. Diam. 30-34 mill. 

East Indies and Philippines. 

Somewhat distinctive in color, but the markings and sculpture of 
the usual patterns. 

Var. FUNicuLATA, Reeve. Figs. 95, 30. 

Black, with scattered white or yellowish white spots on the ribs, 
aperture tinged with yellow. 

Neiv Caledonia to Central Polynesia. 

The ribs vary in number and development, and are often irregular 
in size on the same sjiecimen. Some collectors have confounded it 
with the West American V. scabricosta, but that species is larger 
and more compressed and rounded and generally more rugose. 
Probably N. punctata, Quoy and Gaimard (PI. 7, fig. 30) is identical. 


Var. FLAMMULATA, Recluz. 

Yellowish grey, maculated sjiarsely with black, ribs about 24, 
alternately smaller. Diam. 23 mill. 

Malay Arcldpelago. 

N. scABRicosTA, Lam. PI. 6, figs. 5, 6. 

Shell with numerous, rather close rounded ribs, crossed by close 
scabrous longitudinal strise, dark greyish or black, more or less 
maculated or spotted with orange brown, occasionally irregularly 
banded with the latter; lip black-margined, numerously toothed 
within, with larger teeth at the extremities, columellar teeth very 
strong and ])rominent, the area deeply plicate, with a peri)endicular 
series of three tubercles below, sometimes confluent or obsolete. 

Diam. 30-50 mill. 

Panama, northward to Loiver California. 

The synonyms are N. ornata, Sowb. (fig. 5), N. fuscata, Menke, 
N. Deshayesii, Recluz (fig. Q&), and 'N. multijugis, Menke. I retain 
Lamarck's name for this species although the identification is some- 
what doubtful, Delessert figuring a N. eostata for it; and I do this 
because in the United States the species has been usually so designa- 
ted. Dr. von Martens calls it N. ornata, Sowerby, a name published 
about the name date. The scabrous surface and compressed rounded 
form well distinguish the species. 

Section Odontostoma, (Klein. 1753), Morch. 1852. 

N. POLiTA, Linn. PL (i, figs. 7-11 ; PL 7, figs. 12-23. 

Shell thick, smooth, polished, sometimes with faintly rugose 
growth-lines or very obscure spiral riblets, greyish, flecked or 
spotted or banded with white, yellow, orange, red or black, the 
ground color itself varying rather unusually to one of the other 
colors, with or without flecks and bands; aperture porcellanous, 
polished, thick, outer lip smooth or obscurely dentate w'ithin, colu- 
mellar lip feebly dentate, the area smooth. Diam. 25-40 mill. 

Hed Sea, Indian Ocean, Philippines, Polynesia, Mawritius. 

The immense variation of coloving in this beautiful species has 
been the cause of a considerable duplication of specific names. I 
give examples showing the usual as well as some of the rarer 
patterns of ornamentation. The synonymy includes N. nigra, N. 
flavescens, and N. hieroglyphica, Chemn., N. bidens and JV. bifaseiata, 
GmeL, ^Y. Orbignyana, Recluz (figs. 19, 20).

Closely wrinkled by impressed growth-lines, aperture and colu- 
mella orange-tinted. 

Var. AURORA, Dunker. Fig. 21. 

Closely wrinkled as in Var. antiquata, but the shell less transverse, 
with somewhat elevated spire ; white, with three yellowish brown 
bauds mottled with chestnut, aperture orange-tinted. 

Var. Umlaasiana, Krauss. Fig. 18. 

More obliquely elongated, the outer lip more extended upon the 
spire above, dark olivaceous, mottled with black. 

So. Africa. 
Var. RuMPHii, Recluz. Figs. 8-11, 16, 22, 28. 

Smaller, usually closely spirally striate, coloring often in definite, 
wide or narrow bands, but varying to unicolored, mottled or 
interruptedly banded. 

X. Doreyana (fig. 23) and X. Giiamensis (tig. 22), of Quoy, are 

M. maxima, Gmel. PI. 7, figs. 24, 25. 

Thick, lightly decussated by incremental strise and evanescent 
spiral sulcations, yellowish grey interruptedly banded with black,

Var. OBATRA, Rqcluz. Fig. 25. 

Shell olivaceous black, obscurely maculated. 

Var. trifasciata, Montr, from New Caledonia, appears to repeat, 
on a darker ground-color the banded condition of the type. 

N. BisECTA, Reeve. PL 7, fig. 26. 

Shell with strong revolving ridges and equal intermediate sulci, 
the ridges black and divided in the middle by an incised line, sulci 
yellowish grey ; outer lip many-toothed within, teeth of the extrem-

ously minutely toothed within, columellar area smootli, the margin 
three-toothed. Diam. 20 mill.

N. alveolus, Hombr. et Jacq. (fig. 28), appears to be identical and 
if the date on the title page is correct, was published a year earlier.

spiral ridges; aperture white, lip numerously toothed within, colu- 
mellar area smooth, tlie margin with four teeth. Diam. 22 mill.

With acute, subdistant ridges, frequently in pairs, yellowish grey 
articulated with black ; aperture yellowish, with black spots on the 
margin, columellar area smooth, the margin obscurely dentate, den- 
ticles of interior of outer lip obsolete. Diani.18 mill. 

King George s Island. 

N. MORio, Sowb. PI. 9, fig. 75; PI. 8, figs. 41, 46. 

Black, usually polished, with slightly impressed spiral lines; 
aperture yellowish, the outer lip callously thickened Avithin, but not 
toothed, columellar lip minutely or obsoletely toothed in the middle, 
area somewhat concave, polished, smooth. Diam. 18-22 mill. 

Atistralia, New Zealand, Polynesia. 

Confounded with ^V. atrata, Linn. N. nigerrima, Chemn. N. Sene- 
galensis, Gmel. etc. but differs by the smooth interior of the outer 
lip, as well as by its oblique last whorl. It was described as a 
Neritina, and afterwards by Reeve as ^Y. Neritinoides (fig. 46); 
another synonym is N. carbonaria, Philippi (fig. 41). 

"N". EssiNGTONi, Recluz. PL 8, fig. 45. 

Shell with somewhat high sjjire, black, conspicuously spirally 
sulcate; outer lip smooth within, columellar lip slightly dentate on 
the middle margin, the area smooth. Diam. 18 mill. 


Has much the appearance of ^Y. nigerrima externally, but diflfers 
in its columellar area ; also resembles N. atramentosa, except in the 
absence of the teeth within the outer lip. Very probably they will 
all prove to belong to one and the same species. 

N. picEA, Recluz. PI. 8, fig. 47; PI. 9, figs. 52, 70, 74; PI. 4, fig. 60. 

Shell smooth, polished, with close or distant slight engraved lines, 
black, often showing faint minute greyish flecks, but frequently so 
obscure as to be scarcely visible; aperture white, outer liji without 
teeth, columellar margin minutely or obsoletely dentate in the 
middle, area flat, smooth, polished. Diam. 12-18 mill. 

Japan, Polynesia to Sandivich Is^ 

I have been on the point of merging this in the preceding species 
as a synonym. In its unspotted state it is only distinguished by 
smaller size. iV. obseura, Hombr. and Jacq. (fig. 52), N. insculpta,. 
Reeve (fig. 74), and N. bullula, Reeve (fig. 70), are synonyms,, 
The shell which Philippi has figured for N. picea (fig. 60), if that 
species, is a somewhat abnormal specimen. 


N. AFFiNis, Reeve. PI. 9, figs. 51, 58, 54; PL 8, figs. 49, 50. 

Shell usually transverse, closely, somewhat scabrously spirally 
striate, marbled and speckled with white and grey or olivaceous ; 
aperture bluish white, minutely obsoletely toothed or edentulate 
within the outer lip, columeHar area smooth, the margin obsoletely 
toothed. Diam. 10-18 mill. 

Viti Islands. 

N. Samoensis, Dunker (figs. 49, 50), K costulata, Busch, and 
probably K Vitiensis, Hombr. et Jacq. (figs. 58, 54) are synonyms. 

N. PICA, Gould. PI. 9, figs. 59, 60, 76. 

Usually smooth, sometimes spirally striate, black with cuneiform 
markings or reticulations of white; aperture whitish, the outer lip 
.smooth within, columellar margin minutely denticulated, the area 
flattened, smooth. Diam. 15 mill. 

Japan, Polynesia. 

X. Japonica, Dunker is evidently synonymous, but the figure 
given for that species in Thes. Conch, and which I have inadver- 
tently copied (PI. 9, fig. 58), is evidently something else. N. Melal- 
euca, Martens and N. rudis, Pease (fig. 76), are to be added to the 
synonymy. The figure of N. rudis (copied from Pease), very poorly 
represents the shell ; the types before me are undoubtedly ^Y. pica. 

N. ve;xillum. Reeve. PI. 9, fig. 61. 

Spirally ribbed, with narrow intermediate gi'ooves, orange colored, 
with two broad black, orange-spotted bands; aperture yellowish 
white, outer lip edentulous, columellar margin sharply toothed, the 
area flat. Diam. 22 mill. 

Hab. unknown. 
N. AECTA, Hombr. and Jacq. PI. 9, figs. 64, 65. 

Spirally ribbed, white, witli scattered dark spots; aperture with- 
out teeth, columellar area flattened, smooth. Diam. 17 mill. 

Ami Is., N. of Australia. 

I know nothing of this species ; it has been overlooked, as most 
of the species of these authors have been, by Reeve and Sowerby. 

N. sTRicTA, Baird. PL 9, figs. 67, 68, 62. 

With low spiral ridges, and broad siiallow interstices, whitish 
with scattered black markings, varying to greyish black ; aperture 
yellowish, lip thickened within, edentulate, columellar area smooth, 
the edge obsoletely dentate. Diam. 12-15 mill. 

Polynesia, Xeiv Caledonia. 


X. XorcB-Caiedonice, Baird (tigs. 67, GS), is a syuoiiym. My 
figure of K. drida is unfortunately taken from Sowerby's Thesaurus* 
and is certainly not typical, Baird's figure being exactly like N. 
Novce- Caledonia' in all its features exce])t being darker colored.

Mauritius, Seyehelles, Isle of Bourbon. 

The synonyms are J\\ liturata, Recluz, N. Caffra, Gi'ay, N. zigzag, 
Morelet. Von IVIartens has vars. minor (fig. 78), and subplanispira 
(fig. 79), the latter for depressed specimens. I think that N. ful- 
gurata, Desh. (figs. 97, 98), from Isle of Bourbon, described from a 
single specimen, is simply a light-colored examj^le of this species. 

N. Natalensis, Reeve. PI. 10, figs. 80, SI ; PI. 11, fig. 9. 

Striulate, somewhat shining, yellowish brown with oblique black 
strigations, more or less decurrent or reticulately confluent; aper- 
ture bluish white. Diam. 19-28 mill. 

Mozambique to Natal. 

It is N. zebra, Krauss. N. Moquiniana, Recluz (fig. 9), is an un- 
identified si^ecies from "Islands of the South Sea," which appears 
to be closely related. 

N. variegata. Lesson. PI. 10, figs. 82-86; PL 12, figs. 23, 24. 

Somewhat shining, variegated with yellowish brown and black, 
usually in an irregular net-woi'k jiattern, the meshes large or small, 
sometimes the black reticulations form irregular broad bands, and 
occasionally they cover the entire surface so as to make it nearly 
unicolored ; aperture whitish or bluish white, the columella with a 
tinge of orange-l)rown. Diam. 16-23 mill. 

East Indies, Polynesia. 


The synonyms are JV. Siiviatrensis, Sowb., X. pidchra, Sowb. (figs. 
23, 24), N. gagates, Morch, Clithon Zelandicus, var. helvola, Mous- 
son (not Gould). N. WalUsiarum, Recluz, is black, with inconspicu- 
ous pellucid-white or brown dots, and is probably not distinct from 
N. variegata; I think it likely that N. Guvieriana, Reel. (figs. 85, 
86), should also be placed here. N. pidchra, Sowb. (figs. 23, 24), 
was described as from Panama, Avhere it is believed no such species 
exists. kSowerby's figure shows some reddish zones alternating with 
olivaceous, which are not present in specimens of pidchra received 
from Sowerby as from Panama, but of a number of specimens of 
variegata from the Viti Islands, collected by Mr. Garrett, two have 
this peculiar red banding. 

N. ziczAc, Sowb. PL 10, figs. 87-92 ; PL 11, figs. 100, 5. 

Striulate, shining, olivaceous or yellowish, with zigzag or undu- 
lating radiating black stripes; aperture bluish white, columella 
often tinged yellowish-brown. Diam. 20 mill. 

East Indies, Polynesia. 

According to the relative thickness of the stripes and interspaces 
the pattern sometimes appears to be black on an olivaceous ground, 
at others olivaceous on a black ground. Originally identified with 
N. ziczac, Lam., but is not that species ; yet, as it has become well- 
known under that name, I have not deemed it advisable to adopt 
another for it, as Martens has done. The synonyms are N. strigil- 
lata (Lam.), Recluz, N. aquatilis. Reeve (fig. 100), N. Jovis, Reel. 
(fig. 5), N. ramosa, Meusch., and var. inter stitialis, Martens, in 
which the olive color is replaced by orange brown. 

The true N. ziczac of Lam. appears to be most nearly related to 
N. reclivata. Say. 


Olivaceous, with subtriangular black maculations. 

N. triangidaris, Meusch., and N. pulcherrima and N. insignis, 
Mousson, are synonyms. Martens has adopted this varietal name 
for the species. 

Var. SERKULATA, Recluz.

Northern So. America to Brazil; Porto Ricof, Panama?. 

I find no characters by which to distinguish this from varieties 
of jSf. ziczac, unless it be by the less angulated patcern of the stripes 
and their greater width ; moreover, I know of no such American 
form, and I cannot help thinking that, at least as to some of the 
identifications, the mistake has been made of confounding ^vith it 
varieties of N. reclivata and N. virginea. Entirely similar shells 
are in the Philadelphia Collection, received from Cuming as from 
Taheiti. N. lineolata (? Lam.), of Sowb., Reeve, etc., and N. so- 
hritia, Recluz (fig. 95), are referred here by INIartens. 

N. Smithi, Sowb. PI. 10, fig. 96. 

Smooth, somewhat shining, light olivaceous, with close undulat- 
ing black lines, occasionally confluent into varicose-looking wider 
ones ; aperture bluish white. Diam. 22 mill. 


N. tigrina, Benson, and N. hamtdigera, Troschel, are synonyms. 

N. PLUMBEA, Reel. p. 11, figs. 7, 8.

Length, 25-30 mill. 



iV. fimbria, Meusch., is a synonym. Von Martens and others 
consider X. semiconka a variety of N. tiirrita, but it appears to me 
to have the characters of a distinct species. 

N. RoissYANA, Recluz. PI. 11, figs. 10-13. 

Conical, olivaceous or bluish white, with very close zigzag black 
lines, often wider than the interspaces, so that the whole shell ap- 
pears blackish ; aperture bluish white, the columellar area yellow- 
tinted. Length, 16-20 mill 

Australia to Central Polynesia. 

Shaped like a JSf. turrita in miniature, but with the broad stripes 
of that species replaced by very close zigzag lines. The synonyms 
are N. cuprina, Reel. (fig. 11), K chrysocolla, Gould (fig. 12), N. 
Navigatoria, Reeve (fig. 13), ^V. rivula, Hombr. and Jacq., and N. 
Vitiensis, Mousson. 

N. TuRTONi, Recluz. PL 11, figs. 14, 15.

undulating, oblique, broad black stripes ; aperture light olivaceous- 
or greenish white, columella bright salmon color. 

Diam. 18-25 mill. 

Viti Is., in brackish and fresh water. 

The locality, jSTew Ireland, given by Hinds, needs confirmation. 
The synonymy includes N. lugubris, Sowb., N. Zelandica, Recluz, 
N. helvola, Gould, and perhaps N. mix, Brod., a unicolored brown- 
ish shell from Tahiti.

N. COMMUNIS, Quoy and Gaimard. PI. 11, figs. 16-22. 

Smooth and shining, variously solidly zoned with white, yellow

oblique black stripes ; aperture bluish white, the convex columellar 
area white or yellowish. Diam. 15-21 mill. 

East Indies, Philippines; brackish water. 

The figures which I have selected will give some idea of this 
beautiful species, but there are besides, many other combiiuitions of 


coloring. N. Waigiensis, Lesson, N. strlgillata, Sowb., N. zebra, 
Troschel, N. elegantina, Bnsch, and N. clegmiiissima, Morch, are 

N. RECLivATA, Say. PI. 12, figs. 25-30. 

Shell olivaceous, sometimes light brownish, with oblique, some- 
what undulating or zigzag narrow black lines, usually jDarallel but 
sometimes reticulating, the aperture and convex columellar area 
bluish white. Diam. 15-23 mill. 

Florida, West Indies, Mexico, Central America 

N. lineolata, Lam., is now supposed to be identical, and according 
to printed dates of publication has three months' priority ; but con- 
ceding this, it would still be of very questionable advantage to 
science to substitute a name which has been variously identified for 
one the application of which has never been doubted, and so has 
become well-known. N. zigzag of Lam., not authors, has also been 
referred here. Other synonyms are N. microstoma, d'Orb., ^ 
gravis, Shuttl. and Morelet, N. olivacea, Wiegm., and var. conoidalis, 
Martens, for the conical, lineolate form with parallel strigations; N 
reticulata, Cristofori and Jan, for the specimens with reticulated 
pattern; and jV. striolata, Recluz (fig. 28), iV. Floridana, Shuttlew. 
(fig. 29), and var. rotundata. Martens, for a short-spired form. 

N. viRGiNEA, Linn. PI. 12, figs. 31-45. 

Smooth, polished, usually white, sage colored, yellowish or vio- 
laceous, with a fine, close painting of parallel longitudinal darker 
colored lines, either extending across the entire surface or inter- 
rupted so as to form spiral zones, upon this surface of close lines are 
placed miscellaneously numbers of subtriangular spots of the ground 
color of the shell, sometimes covering it entirely, at other times 
forming spiral bands of large spots, with smaller intermediate ones. 

Diam. 6-20 mill. 

West Indies to Brazil. 

I have figured some of the common as well as the more striking 
color modifications of this elegant and very variable species. There 
are tAvo or three patterns of coloring which are much more comhion 
than the others, yet which cannot be called varietal ; they are 1st, 
whitish violaceous, covered by close violet lines upon which are 
triangular spots ; 2d, a similar pattern, but the colors light and 
dark olivaceous ; 3d, light sage green, with darker lines, but almost 
covered over by the spots which are arranged somewhat as on a 


serpent's skin. The synonymy is enormous, including N. Brasili- 
ana, Recluz, N. trabalis, and K chlorina, Link, J\\ flavojneta and 
N. vinosa, Mouss,, N. Listen, Pfr., N. turriculata, Meuke, N. Matoni, 
Morch, N. meleagris, Lam., N. elegantissima, Hartm. (figs. 44, 45),

Indian Ocean to Polynesia. 

A widely distributed species, which closely mimics the West 
Indian N. virginea. Like that species, it inhabits both brackish

yellowish and flatter. The operculum differs somewhat from that 
of N. virginea, the rib and apophyses are well-developed, nearly 
equally large, with a connecting band almost equally elevated.

I have included in the above de^^cription forms heretofore re- 
garded as distinct, but which do not appear to possess permanent 
differential characters. The principal mark of this species is the 
presence of spiral sculpture, but I have before me specimens in 
which this is partially obsolete, suggesting very strongly a connec- 
tion with N. dubia. The typical ^V. cornea embraces the smaller 
forms, with less developed sculpture, columellar area yellowish, be- 
coming deeper, orange or blackish on the outer edge, the margin 
edentulate. Here may be placed as synonyms N. amphibia and N. 
ampxdiaria, Lesson, N. morio, Deshayes, N. sulcata, Anton, N. Savesi, 
Gassies (fig. 1), and N. gagates, Troschel, with var. atramentaria,

Northern and Middle Europe : Great Britain., France, Holland, 
Germany, Russia, Norway and Stveden, Italy, Dalmatia. 

This common European species is widely distrii)uted in fresh 
Avater, its normal habitat, and occurs also in thermal and salt 
springs, in brackish and even in sea water. Its distinguishing 
character is its transverse form ; the colors vary considerably, but 
the pattern is usually either transverse, nebulous light spots and 
streaks on a dark ground, or oblique dark zigzags on alight ground, 
the difference of appearance being due to the greater or less thick- 
ness and frequency of the dark markings. Fig. 15 represents a 
form from a salt stream; fig. 16 is a marine form from the Baltic 
coasts, known as N. Baltica, Beck, and which is N. littoralis, Linn,

Globosely ovate, a little shining, lightly striulate, unicolored 
black, rarely fulminately strigate on a lighter color; columellar 
area convex, whitish, margin edentulous. 

Asia Minor, Syria, Palestine. 

Has not the spiral stride which rather indistinctly mark N. Anato- 
lica. The synonyms are N. Karasuna, Mouss., and N. Michonii, 

N. Mesopotamica, Mousson. PL 17, fig. 75. 

Lightly striulate, shining, black, usually unicolored, rarely ma- 
culated with white, whorls scarcely convex, the last somewhat flat- 
tened above, wider l)elow ; a2:)erture bluish white, columellar area 
rather wide, plane, minutely rugulose, mai'gin finely denticulate. 

Diam. 6*5-7 mill. 

Upper Mesopotamia. 

Described as a variety of N. meridionalis, and at first considered 
by Martens a variety of N. Anatolica. 

N. ciNCTELLA, Martens. PI. 17, fig. 76. 

Lightly striulate, somewhat shining, greenish olivaceous or black- 
ish, last whorl tumid below the suture, then constricted, base wider ; 
aperture bluish white, columellar area convex, greyish, margin mi- 
nutely denticulate. Diam. 4'5 mill. 

Upper Mesopotamia. 


Lives in same region as the preceding form, but is said to be con- 
stantly distinguished by its constricted whorl. 

N. Perottetiana, Recluz. PI. 17, fig. 77. 

Shell globose, striulate, black, unieolored, whorls scarcely three, 
the last tinged at the suture ; aperture bluish white, columellar area 
plane, narrow, middle of the margin obtusely denticulate. 

Diam. 9-11 mill. 

India, Ceylon, Pegut. 

N. tristis, Phil, is a synonym. 

N. COLUBER, Thorpe. PL 17, fig. 78. 

Undescribed, and only a single figure published, showing the 
back. It is yellowish green, with black zigzag markings, and (if 
not enlarged) is 15 mill. diam. 


N. Jayana, Recluz. PL 17, fig. 79. 

Thin, concentrically striulate, epidermis yellowish, with reticulate, 
flexuously angulated lines, mixed with small white spots ; suture 
narrowly channeled ; inner lip maculated with black, aperture yel- 
lowish. Diam. 6 mill. 

An undetermined species sent by Dr. Jay of N. York to Recluz, 
and therefore doubtfully ascribed to North America. I believe 
that no one has recognized it ; it almost certainly is an old-world 

N. Showalterii, Lea. PL 17, figs. 81, 82. 

Smooth, diaphanous, yellowish corneous, whorls 3, rapidly in- 
creasing, suture inconspicuous, last whorl somewhat inflated, aper- 
ture bluioh white, edentulate, peristome continuous, forming a pos- 
terior raised margin which limits the rather wide columellar area, 
area smooth, slightly concave. Diam. 5'5 mill. 

Coosa River, Alabama. 

Several specimens were obtained, all without the oj)erculum. It 
has been suggested that this is a young Anculosa, but it has not 
the characters of that group ; on the contrary, it more nearly ap- 
proaches in general Neritina crepidularia. The coloring of the 
epidermis more nearly resembles Anculosa however, than the other 
fluviatile species of Neritina.

lescing, or absent, and sometimes intermingled with reddish spots in 
spiral series ; columellar area convex, wide, white, margin distinctly 
toothed. Diam. 8 mill. 

Red Sea, Indian Ocean, Madagascar, Mauritius, Philijipines, 

I think that the un figured N. puella, Gould, from the Loo Choc 
Is., and N. viridissima (figs. 91, 92), of Tapparone Canefri, fall 
within the range of variation in form and color usually attributed 
to N. Rangiana. The latter is a New Guinea species.

Epidermis black, or very dark brown punctate or minutely retic- 
ulated with black ; aperture varying from bluish to yellowish, colu- 
mellar area yellow becoming reddish orange posteriorly, edge very 
minutely dentate, or smooth. Diam. 20-30 mill. 

Australia, New Caledonia, Viti Is. 

Typically distinguishecl by its strong sutural ridge and interven- 
ing channel, but from this character insensibly merges into the 
parent form; the coloring of the coluiuellar region also, varies to 
that of N. pulligera through intermediate shades. 

N. bicanalis, Phil, is a synonym. 

Var. ovALis, Sowb. Fig. 8. 

More transverse, with terminal apex, spirally striated, aperture

ing the spire; aperture bluish white to olivaceous, columellar area 
slightly punctate, flattened, yellowish white or pale olivaceous 
margin minutely dentate. Diam. 25-35 mill. 

Philippines, Moluccas. 

I think it not unlikely that this form will prove to be only a 
color variety of N. puUigera, from which it is distinguished mainly 
by its lighter color and more prominent and diversified markings. 
Like that species it has its varieties depending upon the appression 
or erection of the sutural edge, color of interior, etc ; and as in that 
species, so far as these differences have caused separate names to be 
given them, I have treated them as varieties-si mply for convenience. 

This form is N. pulligera, Quoy and Gairnard, JV. Delestennei, 

Var. Bfxkii, Recluz. Figs. 20, 21, 25. 

Lip rained into a sutural ridge above, columellar area greyish 
black. It is N. 'Knorri, Reeve (fig. 25), N. Brandti, Phil, of which 
N. cornuta, Reeve (Figs, 20, 21) and its Var. Pacifica, Mousson are

pressed, olivaceous brown, transversely reticulated with black,, 
epidermis thin, rough, not shining, aperture bluish white to light 
yellowish, columellar margin edentulous. Diam. 16-25 mill. 

East Indies, N. Caledonia, Philippines^ 

I think that X. arclfera, Morch (fig. 32), will prove synonymous, 
or at most a variety with somewhat more produced spire.

Semiglobose, slightly striate, somewhat shining, olivaceous or 
brownish with subtriangular black spots often in oblique series; 
aperture and columellar area yellowish to orange color, margin 
concave, numerously minutely toothed. Diam. 16-25 mill.

N. SULCULOSA, Martens. PI. 20, fig. 36. 

Closely spirally engraved, striulate, dark olivaceous brown, with- 
out markings; aperture bluish ash color, columellar margin sinuated, 
distinctly rather strongly dentate, area jDlane. Diam. 14 mill.

whorl enveloping the spire, light brown, sometimes Avith a violet 
tinge, varying to black, covered throughout with close light colored 
suboval spots; aperture bluish white, varying to light yellowish, 
columellar area wide, flattened, minutely punctate, yellowish grey, 
edge minutely dentate, Diam. 20-30 mill. 

West Indies, Central America, New Grenada, Bay of Montija, 
Panama to Mazatlan. 

Probably inhabits the sea as well as fresh water; some of the 
specimens have the spire extensively eroded. The distribution on 
both shores of the American continent is singular, but is well- 
established. The species need not be confounded with N. virginea, 
Linn., as has been done; in its spire-enveloping body whorl and 
other characters it is very distinct from that species, and completely 
indentified with the present group. 

The principal synonym is N. cassiculum, SoAvb. (fig. 39), which 
von Martens by an erroneous reference to Sowerby's illustrations 
has referred to N. reclivata, Say ; other synonyms are N. fnscilabris, 
Wiegmann; and N. aperta, Budgin. I think that to these may pro- 
bably be added JSf. Bahiensis, Recluz (fig. 40), from Brazil, and 
N. turbida, Morelet (fig. 41), from Central America — both of them 
young shells. 


N. Afra, Sowb. PI. 20, figs. 42-44. 

Very slightly stviulate, spire somewhat prominent, partially en- 
veloped by the last whorl, yellowish olive to brown or nearly black, 
reticulated with black, often forming obscure spiral l)ands; aperture 
bluish white, columellar area yellowish brown, flattened, the margin 
finely toothed. Diam. 15-20 mill. 

West Coast of Africa. 

As in most sinnlarly marked species, the interspaces of the reticu- 
lations sometimes have the appearance of nebulous spots on a dark 
surface. The synonyms are N. cequinoxialis, Morelet, N. Listen, 
Reeve (figured), JSf. Africcuia, Recluz, iV. r(f6r/c(fto, Morelet (figs. 43, 
44), and N. Calabarica, Mousson.

yellowish, columellar margin sinuous and dentate in the middle. 

Diam. 16-22 mill. 

Sandalwood Bay, Malaysian Archipelago, Viti Is. etc. 

N. cholerica, Gould (fig. 47), JSf. Vanicorensis, Honibr. (fig. 48), 
and N. Caffra, of Garrett are synonyms. There is but little differ- 
ence between this species and JV. propinqua, Mousson in the appear- 
ance of the shell: the latter has not columellar teeth. 

N. ADUMBRATA, Reeve. PI. 20, fig. 49. 

Last whorl a little depressed around, but not enveloping the spire, 
smooth, shining, yellowish olivaceous to brown, closely or coarsely 
reticulated with black, or appearing nebulous on a darker ground; 
aperture bluish w'hite, columellar area flattened, posteriorly orange 
brown, edge slightly sinuous and minutely dentate in the middle. 

Diam. 18-30 mill.

More elevated, brighter color, aud not enveloping the spire like 
the preceding species. 

N. Marchionata, Reeve. PI. 20, fig. 50. 

Rather thin, orbicular, shining, body whorl concavely impressed 
next the spire, with conspicuous waved yellowish and black striga- 
tions, sometimes nebulous; aperture yellowish, somewhat expanded,

to reddish orange. Diam. 30-45 mil). 

Sandwich Is. 

N. papulosa, Jay and N. gigas, Lesson are synonyms. 

Subgenus Clitiion, Montfort. 1810. 

When the spines are developed, as they usually are, there is no 
difficulty in determining these shells; but occasionally the same 
species is spineless, and even some of the species referred here 
appear to never develope spines, in which cases they are only 
separable from Clypeolum by the characters of the operculum. 

N. LONGisPiNA, Reel. PI. 23, figs. 3-5. 

Epidermis varying from rather dark brown to nearly black, the 
lighter colored specimens often with black lines and bands, surface 
plicately rugose, with a series of long, cylindrical spines on the 
shoulder; aperture bluish white, showing the exterior bands, colu- 
naellar area flattened, smooth, usually w'hitish or posteriorly tinged 
with yellow, terminated by a distinct rounded line, margin incurved 
in the middle and edentulous or minutely dentate. 

Diam. 15-30 mill. 

Mauritius, Isle of Bourbon, Rodriguez, Madagascar.

N. spiisosA, Budgin. PI. 23, figs. 6, 7. 

Rather smooth, with a few wrinkles, shining, light yellowish 
brown with irregular black spiral bands, and a corona of moderately 
long, subcylindrical black spines; aperture bluish white, showing 
the bands, columellar area flattened, distinctly circumscribed pos- 
teriorly, often tinged with yellowish, deepening into reddish-orange 
behind, margin a little incurved but scarcely dentate in the middle. 

Diam. 15-20 mill. 



N. undata, Lesson, and vfvr. mermls, Martens (fig. 7), are syno- 
nyms, the latter for specimens in which the spines are broken or 
not well developed ; but I have never seen a specimen without some 
indication of their presence. 

N. SouLEYETANA, Rccluz. PI. 23, figs. 8, 9. 

Rather smooth, shining, black, with white or yellowish, more or 
less interrupted and undulated longitudinal strigations, shoulder 
subangulated, with distant rather short, somewhat stout spines, 
aperture yellowish or bluish white, columellar margin incurved and 
very faintly minutely dentate in the middle. Diam. 13-20 mill. 

Marquisas Is., New Ireland, Moluccas, etc. 

Small specimens entirely devoid of spines are of frequent occur- 
ance. N. Recluziana, Guillou (fig. 10), N. hapa, Hombr. et Jacq., 
and N. rarispina, of the same authors, N. nigrispinis, Lesson, and 
var. Studeriana, Martens are synonyms.

bluish white or yellowish white, slightly sinuous on the middle of 
the columellar margin — which is minutely dentate throughout, 

Diam. 15-21 mill.

East Indies, Philippines. 

N. aranea and N. cryptospina, Mousson are synonyms. 


Var. spiNiFERA, (Recluz) Sowb. Fig. 14. 

Reticulated with reddish browu. It is very doubtful whether 
this is the spuiifera of Recluz. 

Var. DoNOVANA, Recluz. Figs. 12, 13. 

With subvertical flexuous reddish or blackish strigations. 
N. strigillata, Canefri is a synonym.

unarmed, or with a shoulder somewhat shortly spinose, yellowish 
brown, with granules whitish, varying to darker brown or nearly 
black, sometimes obscurely maculated or indistinctly banded, some- 
times pinkish under the epidermis; aperture yellowish or bluish 
white, columellar edge usually edentulous in large specimens, mi- 
nutely faintly dentate in small ones. Diam. 1 in. 

East Indies to Central Pacific. 

A very common, widely distributed form which rejoices in an 
extensive synonymy. It is N. corona, Linn, in part (figs. 16, 20.) 
N. spinosa, Wood, jV. variabilis,- Jjesson, N. cardinalis, Guillou, N. 
Montucute, Recluz, N. musiva, N. flexuosa, and N. corrugata, Hombr.

Marts., in which granules tend to unite into longitudinal plicee. 

Var. ANGULOSA, Recluz. Figs. 21, 22. 

Irregularly longitudinally plicate, blackish olivaceous, usually 
Avith minute yellowish spots, which are sometimes black margined, 
sometimes replaced by short black lines, spines scarcely developed 
on the' shoulder. 

Typically, this form seems very distinct, but it passes into brevis- 
pina by intermediates; one of these is N. obscurata, Reel, others are 
N. discors, Mart. (fig. 24), and N. ruginosa, Reel. (figs. 31, 32), — 
of which N. aspersa, Reel. (fig. 33), N. humerosa, Mousson N. sub- 
rugata, Baird. (fig. 34) are synonyms.

With elevated, obliquely longitudinal rugre, olivaceous gi*een, or 
light greenish pink, with undulating brown or black lines, sometimes

Plicately striate, olivaceous brown, with occasional yellowish 
maculations, sometimes black-margined, occasionally triseriate, 
slightly shining, peristome yellowish within, sub-thickened, columellar 
margin obtusely dentate in the middle, upper tooth much larger, 
area slightly rugose, orange-yellow. Diam. 6'5 mill. 

Isl. New Britain. 

Only known to me by the description and figure, but appears not 
unlike a spineless JV. brevispina. 

N. H^MASTOMA, Martcus. PI. 24, fig. 37. 

Striulate, olivaceous brown, with small yellowish, black-margined 
sjjots; aperture bluish white, columellar margin slightly incurved in

figs. 83-85. 

Smooth, somewhat shining, greyish, varying to violaceous, light 
brown or black, with numerous, usually minute white dots and 
spots which, when the ground color is light, are black-margined, 
sometimes indistinctly darker banded; apertui'e whitish, yellow, 
olivaceous etc, columellar margin scarcely sinuous in the middle, 
edentulous, or obscurely dentate, area plane, smooth, often tinged 
with yellow posteriorly. Diam. 7-12 mill.

Closely striulate, subopaque, olivaceous, with subtriangular yel- 
low markings, bordered on the basal margin with black, aperture 
bluish or yellowish, columellar margin siuuated and obtusely dentate 
in the middle, area light greyish yellow, slightly rugulose. 

Diam. 14-17 mill. 

Southern Japan, Siam, Viti Is. 

I susj^ect that this will prove a variety of the preceding species. 
The synonyms are N. obtusa, Reeve, (fig. 41), N. nuhila. Martens, 
and N. obscura, Diinker. 

N. CASTANEA, Hombr. and Jacq. PI. 24, fig. 42. 

Minutely flexuously striulate, somewhat sharply so above, dark 
brown, with black zigzag longitudinal lines, so obscure that they 
are not usually visible except when the surface is wetted, epidermis 
of last Avhorl appressed to and partially or entirely covering the 
spire; aperture bluish white, columellar margin slightly sinuous, and 
scarcely dentate in the middle, area flattened, minutely punctate 
and rugose. Diam. 15-18 mill. 

Samoa and Caroline Islands. 
X. j^ropinqua, Mousson is a synonym. 

N. RETUSA, Morelet. PI. 24, figs. 43, 44. 

Subrugosely striate, soiled olivaceous, with scarcely visible brown- 
ish maculations, with short spines on the shoulder in the young state 
which are mostly lost in the adult; aperture yellowish white, the 
columellar area becoming orange color behind, edge sub-emarginate 
in the middle and minutely dentate. Diam. 12 mill. 

JSfeiu Hebrides. 

N. Sow-ERBYANA, Recluz. PI. 24, fig. 45; PI. 25, figs. 46-51. 

Solid, subopaque, closely, faintly striate, shining, yellowish brown, 
orange brown or rosy, frequently with minute white and red spots, 
sometimes more or less interruptedly bauded or longitudinally 
strigate with black; aperture usually bluish white, columellar mar- 
gin dentate for most of its length. Diam. 10-15 mill. 

Gulf of Siam, China, Japan, Philipjnnes. 

Great as is the typical difference between this species and N. 
brevispina. Lam., I have specimens before me which seem to estab- 
lish a passage between that species and the granvilar, spineless form 
of the latter, N. pulehella, (figs 50, 51), Recluz, and JSf. Soiverbii, 
Reeve, (figs. 48, 49), are synonyms. 


N. AVELLANA, Recl. PI. 25, figs. 52-55. 

Solid, irregularly striate, subopaque, somewhat shining, olive 
grey, yellowish or orange-red, with articulated black bands; aper- 
ture bluish white, columellar area minutely j^unctate, the margin 
sinuous in the middle, and obsoletely dentate. 

Borneo, Formosa, Philippines. 

I fear that this will prove synonymous with the preceding species. 
The synonyms are N. dubia, Issel (^=var. Isseliana, Martens) and 
vars. 2)6tholata, and cJdorostida, IMartens. 

N. FABA, Sowb. PL 25, figs. 57-60. 

Solid, irregularly striulate, shining, yellowish or reddish, more 
or less interruptedly strigate or reticulated with chestnut or black, 
sometimes black-banded ; aperture bluish white, columellar margin 
scarcely sinuous in the middle, obsoletely dentate. 

Diam. 15 mill. 

Western part of the Indian Archipelago, Singapore, etc. 

My only specimens of this species, types from its author, strongly 
indicate identity with N. Soiverbyana. N. Baliensis, Mousson, and 
the color-varieties strigosa, sagittata and fasciata. Martens are 

N. iNTERRUPTA, Recluz. PI. 25, fig. 56. 

Solid, striulate and occasionalty subplicate, yellowish, with fine 
olivaceous somewhat anastomosing longitudinal lines, often interrupt- 
ed partially, 'to form lighter colored spiral bands, young shells 
frequently and old ones occasionally with several short spines above- 
aperture bluish or yellowish, the columellar margin dentate nearly 
throughout, with stronger teeth at the extremities of a central sinus, 
area subrugose and minutely punctate, usually tinged with bluish 
black behind ; often the base of the shell has a jet-black fasciole. 

Diam. 9-16 mill. 

Philippines; New Caledonia. 

Von Martens considered the species of Recluz a synonym of N. 
avellana; on the contrary it ap]3ears to possess all the characters of 
the more recently named New Caledonian N. nucleolus, Morelet, 
(fig. 63). N. plieata, and N. Pazii, Gassies, and var. spinifera. 
Martens are synonyms. The unfigured N. costulata and ^V. Artensis 
of Gassies, likewise New Caledonian, are probably to be added. 


N. RARispiNA, Mousson. PI. 25, figs. 65, 66. 

Striate, dark greenish, minutely punctulate with black, last whorl 
obtusely angulated, and obsoletely or shortly spinose; aperture 
bluish, columellar area rather narrow, plane, margin with a dentate 
median sinus. Diani. 6-9 mill. 


According as the shell is with or without spines, Mousson has 
made varieties spinosa and destltuta,— which, of course, have no 
varietal value. The species itself has not been identified. 

N. Tritonensis, Guillou. PI. 25, fig. 61. 

Greenish, with arcuate longitudinal yellowish lines, spire entirely 
eroded, flat; aperture oblique, with a rather narrow, flat area, its 
margin subarcuate, unidentate, lip rounded, depressed above. 

Triton Bay, Nero Guinea. 

The above is a copy of the original description — which was not 
illustrated. The figure is from Reeve, and I cannot believe that it 
pertains to the same species; it looks more like N. chlorostoma, Brod. 

N. BicoLOR, Reel. PI. 25, figs. 68, 67, 69 ; PL 26, fig. 75. 

Shell j^licate-striate, the body whorl enveloping the spire, some- 
what shining, closely finely strigate with r.lternate yellowish and 
olivaceous green, sometimes minutely punctate with the lighter color 
ujDon the darker, as though serrating the margins of the strigations; 
aperture bluish white, columellar area flattened, subrugose, margin 
slightly incurved and faintly dentate in the middle, the curve boun- 
ded by a stronger tooth above. Diam. 15-27 mill. 

East Indies to Philipjnnes. 

It is N. eelata, Recluz, (fig. 69), N. s'ubpunetata, Recluz, (fig. 67), 
iV. rugata, Souleyet, N. rugosa, Bush, JV. punctifera, Mousson, and 
varieties glandiformis, Molluccensis and tricolor of Martens — the 
latter with reddish brown rug?e and a basal zone of the same, with 
elongate triangular diaphanous yellowish maculations. I have not 
seen this variety, nor has it been figured except a section showing 
coloring, but I can scarcely believe it to belong here — the pattern 
is more like N. avellana. Finally in N. WalUsii, Mousson (fig. 75) 
=N. rugata, Gallies, we have a sparsely spinose form which appears 
to connect very closely with the spinose form of the next species. 

N. OLivACEA, Recluz. PI. 26, figs. 71, 72 : PI. 25, fig. 70. 

Smooth, slightly striate, dark olivaceous varying to brownish with 
obscure black undulating lines, often obsolete, occasionally with one 


or two short spines above, but mostly without them ; aperture bhiish 
Avhite, columeUar area flattened, subrugose, sometimes bounded by 
a callous orange-brown fasciole, edge incurved in the middle and 
dentate there, and slightly so above the curve. Diam. 15-24 mill. 

Moluccas, Philijjjyines, Viti Is. 
N. inconspicua, Busch is a juvenile, and N. suhocellata, Schepmaun 
(fig. 70). a spinose specimen ; other synonyms areiV. solium, Recluz, 
=iV. dolium, Rve., (fig. 72). I suspect that this will, after all, jjrove 
a smooth form oi N. blcolor, Recluz. Mousson has described a var. 

N. FLAvoviRENS, Busch. PL 26, figs. 76, 77. 

Lightly striulate, sliining, greenish with yellow, black-margined 
maculations, sometimes a few spines at the suture ; aperture bluish- 
white, columellar margin with a denticulate sinus, terminated by a

Uniform olive green, roughly longitudinally ridged, ridges some- 
times articulated, young shells with an obtuse shoulder bearing an

Shell with revolving ridges elevated into nodes and short spines, 
olivaceous brown ; aperture bluish white with yellowish bands, col- 


umellar margin slightly .concave, multidentate, area flattened, mi-

The synonyms are N. Michaudi, Recluz, (fig. 89) N. reticidaris, 
Sowb., N. capillulata, Gould, of Sowb., N. Morchiana, Frauen., N. 
humeralis, Theob. Perhaps N. fxdgetrum, Reeve (PI. 12, fig. 30) 
which I have described on p. 38, and for which no habitat is given, 
should also be referred here. 


N. Dringii, Recluz. PI. 26, figs. 90, 91. 

Rather thiu, whorls obliquely rugulose, with yellow bands ou a 
blackish ground, sometimes obliquely longitudinally strigate with 
black or brownish and yellow ; aperture bluish, tinged with yelloAV

subarcuated and dentate in the middle. Diam. 12 mill. 

Hanover Bay, N. Australia.

Solid, irregularly striulate, not shining, greenish grey ; brown- 
spotted ; aperture grey or greyish brown, columellar area plane, 
yellowish, the margin with one to three obtuse denticles. 

Diam. 9 mill. 

Comoro Is. 

Unfigured species, jn'obably belonging to CUthon.

N. CORONOIDES, Lesson. Ne^v Guinea. 

N. PENiciLLATA, Gould. New Ireland. 

Subgenus Neripteron, Lesson, 1830. 

In the diagnosis of tins group (p. 8), the cohinielhir margin is 
stated to be edentulous, but this is in fact, only occasionally the case ; 
usually there are traces of teeth, and sometimes they are very dis- 
tinct, although small, 

N. AURicuLATA, Lam. PI. 21, figs. 58-63. 

Rather convex, slightly striate, somewhat shining, brownish or oli- 
vnceous, obsoletely reticulated with black lines or with lighter spots ; 
aperture yellowish white, bluish black around the lip and on the 
columellar area, margin of columella a little arcuate in the middle, 
and minutely or obsoletely toothed. Diam. 15-25 mill. 

Ceylon, East Indies, Philippines, Viti Is.

trata (figs. 61, 62), and N. Layardi (fig. 63,), Reeve, as well as var. 
inaurita, Morch.

colored, a little shining ; aperture ash color, peristome reddish, col- 
umellar margin minutely multidentate, area large, a little rugose, 
slightly convex. Diam. 12 mill. 

Kapera River, Borneo, on floating timber. 

Supposed to differ from the preceding species by its small size, 
want of reticulated markings, etc. I think it will prove identical. 

N. Tahitensis, Lesson. PI. 21, figs. QQ, 67. 

Striate, and spirally slightly engraved with subdistant lines, light 
olivaceous brown, without markings ; aperture greyish blue or yel- 
lowish grey, columellar margin slightly sinous and minutely dentate 
in the middle, columellar area slightly rugose and minutely punc- 
tate. Diam. 19-25 mill.

The synonyms are X. auriealata, Sowb., N. Lamarckii, Desh., 
N. marginata, Hombr. and Jacq., N. vespertina, Nuttall (PI. 22, fig. 
71), and K Sandivichensis, Reeve (PI. 22, fig. 73). 


Von Martens separates N. vespertma on account of a slight differ- 
ence in convexity of whorls, and habitat, but in the large series 
before me frojn both Taheiti, and Sandwich Is., the supposed local 
peculiarities disappear. 

N. Christovalensis, Keeve. PI. 21, figs. 68, 69. 

Convex, striulate, yellowish, with spiral bands of reddish chestnut 
markings ; aperture yellowish, columellar area slightly arcuate and 
minutely dentate in the middle. Diam. 19 mill.

The ears are usually broader than in the specimen figured, but 

the depressed form and markings are pretty constant in the series 

before me. It is X. biauriculata, Reel.

Very convex, with numerous elevated close spiral lines, olivaceous 
brown, spirally more or less liueated with black ; aperture lead color 
or yellowish grey ; columellar margin incised, minutely and reg-

body whorl convex, swollen, dilated into wings above and below, 
spire visible, flattened, epidermis black or very dark brown, with 
nnmerous close minute yellowish spots, sometimes scarcely visible ; 
aperture bluish, sometimes yellowish, columellar margin scarcely 
arcuate in the middle and slightly dentate, terminating with a larger 
superior tooth. Diam. 18-25 mill. 

Sandwich Is. 

In young specimens the wings are often not developed, and then 
the shell would scarcely be taken for a member of this group. Von 
Martens changes the name to N. Sandwichensis, Desh. because he 
thinks that Gray's figure should be referred to N. Maiiritii. Lesson ; 
I do not agree with him : the figure appears to me to be decidedly 
that of the present species. Other synonyms are N. Nuttalli, Recluz. 
N. convexa, Nuttall, N. solldissima, Sowb., N. lugubris, Phil., N. per- 
striata, Mousson, N. tristis, Phil., N. affinis, Recluz., (=A". lugnbris, 
Sowb. fig. 83.)

Rather more depressed than the preceding species, with the wings 
larger and more dilated, somewhat rugose, epidermis black, unicol- 
ored ; aperture bluish white, columellar nuirgin minutely dentate in

out with zigzag black reticulations ; aperture bluish white or yellow- 
ish grey, columellar margin slightly arcuate and dentate in the 
middle. Diam. 16 mill. 

Taheiti, in streams. 
iV. navicellina, Guillou, N. florida, Recluz are synonyms. Von 
Martens refers here jS\ Owenii, Wood's Index Test. Suppl. t. 8, f. 
16, but it appears to me to belong to the next species. 

N. LATissiMA, Brod. PI. 22, fig. 87-89. 

Finely striulate, Avith produced but broadly rounded ears, oliva- 
ceous or brownish black, reticulated A\'ith black or triangularly

Slightly, closely striulate, yellowish or brownish olivaceous, with 
a small or large reticulating pattern of black lines, often forming 
triangular light spots, last wdiorl usually enveloping the spire ;

Genus NAVICELLA, Lam., 1809. 
Section Cimber, Montfort, 1810. 

The shells of the Navicellee are modified in form and convexity 
according to the nature of the surface to which they adhere ; thus 
the form called N. lineata, is a N. tessellata, higher and laterally 
compressed from inhabiting the stems of sea- weed, whilst the typical 
N. tessellata is from surfaces giving the shell a chance to spread ; so 


also the projection of the apex varies so that it may reasonably be 
considered as effected by environment; again, the central projection of 
the septum, usually conspicuous in JV. Freycineti, is sometimes want- 
ing in that species, whilst it occasionally occui's in others. Thus the 
sectional characters (made subgeneric by Messrs. Adams), insensibly 
coalesce. As to coloring, certain patterns have been regarded as 
characteristic of species, but there appear to be no breaks in the 
modifications by which most of the species may be connected. 

In the interest of scientists (and so, perhaps, of science) it becomes 
necessary to set iq^ some arbitrary landmarks, be they varieties, 
species or sections, it matters not, for the recognition of certain 
stages of the variations else in unbroken progresssion, and to these 
stages the names given by naturalists at a time when species were 
entities have been applied. This task Dr. von Martens has per- 
formed as well as his opportunities, learning and experienced judg- 
ment permitted : if I have succeeded in making any improvement, 
it is due to having his work as a foundation. 

N. BoRBONicA, Bory. PL 27, figs. 2-12. 

Rather convex, apex small, somewhat attenuated, produced be- 
yond the posterior margin ; color varying from dark chestnut brown, 
unicolored to light olivaceous brown, or tinged with purple and 
marked with radiating reiiculations, interior bluish or blackish, 
the posterior margin usually with a long black stain on either side. 

L. 25-40 mill. 

Mauritius, Ins. Bourbon, Madagascar, Seychelles Is. 

It is N. ellij)tica. Lam., (fig. 3) N. tabernaculata, Montf., iV. por- 
ce/lana, Recluz, not Linn., N. Cookii, Recluz (figs. 4, 5), iV. bimac- 
ulata. Reeve (fig. 6), var. triloba, Martens=A\ apiata, Sowb. in part 
(fig. 7), N. livida, Rve. (fig. 9), very similar to var triloba, Yiir. com- 
pressa, ]V[artens = J^. affinis, Reeve (fig. 8). I do not separate as 
such the two varieties given by Dr. von Martens, because such forms 
occur in all the species and are the result of station upon the growth of 
the individual. The black markings which Reeve has commemorated 
in his name bimaculata are very usually, but not always present, and 
unfortunately occur in other species. A more depressed form has 
been treated by von Martens as a distinct species, but seems to con- 
nect insensibly with Borbonica ; it is called N. depressa, Lesson, 
(figs. 10, 11), and N. zebra, Lesson, N. hai(strum. Reeve (fig. 12) and 


its var. fissa, Mousson, N. hupeana, Gassies and N. affinis, Mousson 
are referred to it as synonyms. It occurs from New Caledonia to 

Both iV. borbonica and the form depressa have been x'eferred to 
N. porcellana, Linn., but that species, devoid of epidermis, must re- 
main unrecognizable. 

Morelet has figured (Jour, de Conch., Oct. 1887) a color variety 
from the (Jomoros Is. It is large, and bimaculate with vermillion 
inside in young as well as adult individuals.

with its var. truncata, Mousson, are synonyms. N. parva, Mousson 
(PI. 28, figs. 23, 24), from the Malay Archipelago appears to 
have no distinctive character, except its nuich smaller size: I think 
it is identical.

Von Martens unites this species with N. tessellata, Lam., and I 
have no doubt that he is correct, but the latter might with equal 
propriety be united with N. sub orbicular is, etc. : in fact, the charac- 
ters in this group anastomose in every direction. 

N. navicula, Fer., and N. pictinxUa, Garrett (fig. 60) are syn-

Port Lincoln, Australia; Japan; Viti Is. 

It is C. diatreta, Gould, and Delphinula nivea, Reeve. The latter 
attribvites his species to Chemnitz, who in this, as in many other 
instances was not binomial. C. lactea, Jouss, (figs. 79, 60), a species 
described as differing from loevis in the regularity of its keels, also 
appears to belong here, for the keels are very irregularly developed 
in number, prominence and spacing; it was described from a single 
specimen, without locality.

Isl. Zebu, Philippines; Guadeloupe, St. Martin, W. Indies. 

C. angulata. A, Ad. was described as from the Philippines on the 
authority of Cuming, but as that great collector sometimes made 


mistakes, the locality needs confirmation. There can be no doubt of 
the identity with this species of C. Beaux, Fischer (fig. 63), a West 
Indian species.

two, narrow thread-like keels at the upper part, and strongly keeled 
round the umbilical region, suture distinct; aperture subcircular, 
lip simple. Diam. 2*5 mill. 

South Australia. 

" The above is the normal condition of the species ; but examples 
occur which are thinner and have a greater number of keels, some- 
times as many as seven or eight. At first I was inclined to regard 
the many-keeled variety as specifically distinct; but on the examina- 
tion of a large series by Professor Tate, he assures me that the 
number of keels varies so greatly that it would be impossible to 
separate them. The thin hyaline examples with many keels are 
probably younger shells." 


I have figured both the illustrations given by IMr. Angas. If his 
above remarks be well-founded, which I am very willing to believe, 
several species herein described, and which are principally distin- 
guished by the number of revolving riblets will need to be suppressed ; 
that of the inconoclast himself will be deservedly lost in the general 
ruin which he has caused.

Adams very curiously publishes this as Chemnitz's nivea, and 
says that it is exactly similar to the figures in the "Couehylieu

JJnfigured Species. 

Neither Adams nor Carpenter figured any of the numerous species 
described by them. I have been able to illustrate a few of the 
species of both authors, by drawings from authentic specimens; many 


of the others might be identified in the type collections of these 
authors, but tlie labor and expense attending such an investigation 
Avould scarcely be repaid by the result. The paucity of material 
and minuteness of the species must prevent satisfactory conclusions, 
most of the descriptions being based upon dead specimens, unique 
or few in number.

Conservator of the Conchological Section, Academy of Natural Sciences 

of Philadelphia. 


Animal with an oval, broad or narrow foot, truncated anteriorly; 
rostrum rather short, truncate; tentacles long, slender, cylindrical, 
the eyes on peduncles at their exterior bases. Across the front of the 
head, between the tentacles extends the more or less developed 
"veil" ; and from a point below the tentacles, a fleshy ridge, the 
"epipodial line" extends backward parallel with the margins of the 
foot, and bearing usually several slender cirrhi on either side. 

Radula rhipidoglossate, usually with the formula go 'b'Vb'oo , but 
sometimes lacking the median and one outer lateral tooth. The 
lateral teeth are all of nearly the same form ; so that a transverse 
row of teeth shows only three distinct forms. Jaws usually present. 

Shell turbinate or trochiform, generally solid, smooth or rugulose; 
aperture circular, oval or subtetragonal ; peristome simj^le. Oper- 
culum calcareous, heavy, flat or concave with a thin corneous layer 
internally, convex and calcareous externally, the nucleus multispiral 
and either subcentral or at the margin. 

The nervous system is chiastoneurous ; ( i. e. the viceral nervous 
loop surrounding the intestine is thrown into a figure 8 form — the 
right cord passing above the left — by that torsion of the viceral mass 
which brings the outlet of the digestive tract to the right side of the 

The Turbinidce are mostly litoral in station, and inhabitants of 
tropical and subtroj^ical seas. They are herbivorous.

Dr. Paul Fischer, in his excellent Manuel de Conchyliologie, divi- 
des the TurhinicUc into three subfamilies, defined as follows : 

" I, Phasianellince — shell not nacreous ; II, Turbinince — shell na- 
creous ; outer surface of operculum with few whorls ; III, Cydonem- 
atince, — shell nacreous, outer surface of operculum conical, elevated, 
scalariform, with very numerous whorls." 

The last group, embracing Cydonema Hall, Oriostovta Munier- 
Chalmas, and other exclusively fossil genera will not be further 
considered here. 

Contrary to the usual custom, the more aberrant subfamily, Phas- 
ia?ie^Zwice, will be considered before taking up the Turbinince; this 
course being less objectionable than the unnatural sequence of groups 
which would result from interpolating the Phasianella? between the 
Turbines and the Trochids. 

Subfamily Phasianellin.e. 

Shell bulimiform or subglobose, polished, without epidermis or na- 
cre, variegated with bright colors; operculum heavy, calcareous, inter- 
nally paucispiral, with nucleus near the basal margin, extei'nally 
convex, white; animal with long tentacles, and usually pectinated 
head lobes ; epijwdial line generally with cirrhi ; branchial plume 
long ; foot narrow, long, pointed posteriorly, rounded before, beloAV 
divided longitudinally by a median groove; jaws rhomboidal, cov- 
ered with imbricating scales. Radula rather short ; formula of teeth 
typically oo "S'l'S" oo, but sometimes lacking the median and outer lat- 
eral teeth. 

The considerable diversity which has been observed in the denti- 
tion of the Phasianellince renders a brief review of our knowledge of 
that organ in the various groups desirable. Unfortunately the soft 
parts of i'HCosj/u'rt, Chromatis and Alcyna have not been observed ; 
and I have been unable to obtain specimens of them containing the 

Phasianella{ty\)\^i•^i\). The radulaof P. a^/s^ra^ts has been figured 
by Eberhard. A transverse row of teeth forms a w- shaped line. 
The median tooth is wide, oval, a simple plate, without cusp, over- 
lying the bases of the inner laterals ; the lateral teeth (" Zwischen- 
platten " of Troschel) are of a rhomboidal form, and bear well de- 
veloped cusps with a long and several small denticles ; the outer 
(fifth) one is narrow ; marginals (" Seitenplatten ") with long 
sini{)le cusps, except the inner, which bears accessory small denticles 


at the base of the cusp. (PI. 61, fig. 1.) It is desirable that ad- 
ditional specimens be examined. 

Tricolia. The type species, P. speciosa, has a broad simple median 
tooth, overlying the bases of the inner laterals ; these are sub-rhom- 
boidal, produced at their outer angles into wings Avhich overlie the 
bases of the adjacent tooth outward, and have denticulate cusps. 
The outer lateral is narrow, not produced on the outer angle. The 
mai'giual teeth have long simple cusps, (pi. 60, fig. 72.) Troschel 
has figured the radulse of P. pulla, (pi. 61, fig. 2.) P. Kochii and 
P. capensis, all agreeing with P. speciosa. The following also I have 
found to be of the same type.; P. tenuis, P. umbilicata, P. comptci, 
P. affinis, P. fordicma. The jaws of the latter species are figured 
(pi. 60, fig. 69). Several of these species lack the outer lateral tooth, 
the formula being go" 4' 1. •4" oo . 

Orthomesus. In this group the median tooth is reduced to a lin- 
ear rudiment or wholly absent. The lateral teeth are of a squareish 
form, their outer angles scarcely or not at all " winged," and but 
slightly or not at all projecting over the adjacent tooth. They form 
straight rows across the middle of the membrane, not V-shaped, as 
in the preceding groups. In the typical species, P. variegata, the 
laterals bear long cusps, with minute sj^urs at their bases ; the inner 
marginals are very large, with enormous cusps, the outer ones with 
long denticulate or laciniate cusps (pi. 61, figs. 3, 4.) Troschel fig- 
ures this type of dentition for P. variegata, P. flammulata, Phil, and 
P. lineolata. I have found the same in P. nivosa Rve., (=P. varie- 
gata Lam.). In P. virgo Angas (pi. 60, fig. 70) I have found an ex- 
tremely peculiar and interesting modification of the Orthomesus type 
of dentition. The two inner lateral teeth are united by their inner 
edges, forming a pseudo-median tooth ; the free laterals remaining 
are three in number on either side, and are of the same form as the 
one shown in the figure. As in the smaller species of Tricolia, the 
narroAV outer (fifth) lateral has evidently been lost. The marginals 
all have long laciniate cusps. The lateral teeth have the basal plate 
projecting at the upper outer angle, forming a sort of hood, which 
reminds one of a similar structure in the median teeth of Littorina. 
This " hood," marked a in the figures, is probably homologous with 
the similarly mai'ked basal plate which projects above the cusps in 
P. variegata, etc. The reduction in number of the teeth in this form 
is probably due to the same cause which has, I believe, acted in the 
mure minute members of the Pulmonata and other groups which 


have nuinerous teeth ; if the individual teeth were reduced iu size in 
the proportion that the shell is, they would be too minute to fulfil 
their function as efficient rasps.

Fischer, in Kiener's Coquilles Vivants, 1873. 

Sowerby, in the Thesaurus Conchyliorum, 1884. 

Philippi's work is perhaps the best; but lie describes many species 
characterized only by the color-pattern. Reeve unites all the 
smaller and more difficult species, and redescribes most of the larger 
several times. Fischer's work includes only a few species, but these 
are well described and beautifully figured.

is of a pinkish-cream color, with rather distant, narrow, spiral white

rather short ; it is always, however, longer and with much less convex 
whorls than P. ventricosa.^

P. coTURNix (Koch) Philippi, 1853. PL 39a, fig. 17. 

This is a species of about 15 mill, alt., rather solid, very smooth

lip ; the color consists of a wliitish ground with yellow flames, which 
behind are bordered with dark and l)rown, and in front ai-e dift\ised 
in the clear ground-color, which here and there shows undulating 


yellowish longitudinal lines. There is no trace whatever of spiral 
lines; and in this respect T. coturnix differs wholly from T. flammu- 
lata, a species otherwise very similar.

A/l tropical and subtropical seas. 

I have included in this group most of the smaller species, although 
the characters of the animal have not been described in the larger 
number of them. The dentition in the type species, P. speciosa, is 
not very different from that of the typical species of Phasianella. 
The synonymy includes TrlcoUella Monts., 1884, type, P. pulla 
L., (not intermedia Sc. as stated by some authors), and Eudora 
Leach, 1852, type P. pulla L. Troschel wholly mistook the char- 
acters and limits of this group ; a fact which should be born in mind 
when studying his figures and descriptions.

The markings above described are occasionally obsolete. There 
are several flesh colored specimens before me. Fresh shells some- 
times show ill defined revolving stripe. It is extremely similar to 
P. pulla in coloration, but is more globose. Probably this species 
and P. capensis will prove to be identical, the latter name having 
priority. Both are, I believe, quite distinct from F. pmlla L.

West Indies. 

P. minuta Anton (?), P. zehrina d'Orb. (figs. 99, 100.), and P. 
tesselata C. B. Ad. are synonyms. 

This species and the P. affinis are very abundant in many AVest 
Indian localities. They are usually associated together. Fresh 
specimens of both exhibit microscopic revolving impressed strije. 
Reeve, who has subdivided the larger species of this genus so minute- 
ly, "lumps" these forms, with most of the other small species, under 
P. pulla L. I have never seen a specimen among hundreds I have 
examined from the West Indies which could not be most readily 
separated from the Mediterranean shell. Indeed both affinis and 
tessellata exhibit a surprising uniformity in color-pattern and form. 
The dentition of affinis differs from that oi pulla. P. perforata Phil. 
I should be inclined to unite with tessellata were it not from the 
West Coast. , 

The P. concolor of Adams I have identified with a rather rare 
color-variety whicli generally, occurs with P. tessellata. It is extremely 
dark, almost unicolored ; but with a glass one can perceive still 
darker diagonal lines upon the surface. This form is figured on PI. 
45, fig. 1. The following description is from the original one of 
Adams : 

P. concolor C. B. Adams, 1850. 

Shell rather long ovate-conic; uniform glossy brown, rarely with 
a sutural band of a deeper shade of the same; surface polished, 
apex rather obtuse; sutures impressed ; spire with nearlj- rectilinear 
outlines; whorls 5, convex, the last subangular; aperture ovate; 
columella with a thick deposit, and witli an umbilical indentation.

by deeply impressed sutures, and encircled by rather coarse revoh - 


iug impressed Hues; spire conic, the upper whorls sometimes carinate 
or biangulate from the prominence of one or more of the revolving 
strise; last whorl obscurely angular around the lower part, some- 
times rather acutely carinate above the periphery; aperture less 
than half the length of shell, rounded ovate, columella arched, 
scarcely thickened; umbilical region deeply grooved and narrowly 
umbilicate; color white, sparsely punctate with red, more or less 
flammulate longitudinally with red and white. Alt. 5 mill. 

Cuba; Florida. 

The revolving stride are entirely wanting on some individuals. 
There is great variation in the degree of exsertion of spire, some 
shells attaining a length nearly double that given above. 

The more stable characters of the shell are its narrow but decided 
umbilicus, and the very convex whorls. 

D'Orbigny described the smooth form of this species, as will lie 
seen by his diagnosis translated below: 

"Shell elongate, thin, smooth, umbilicate, punctate with red, 
maculate with red and white; spire elevated, apex acute, whorls 5, 
convex, separated, the last anteriorly subangulate ; aperture oval." 

P. PERFORATA Phil., 1848. PI. 38, fig. (32; PI. 39a, fig. 12. 

"Oblong-conoid, perforate, white, subtessellated with oblique pur- 
ple lines; suture and periphery ornamented with large maculations 
of white and purple; whorls deeply convex, last subangulate; aper- 
ture oblong ovate, equal to spire." 

Payta, Panama; Mazatlan. 

"This beautiful shell closely resembles the West Indian species- 
Like many of its congeners, it has parallel diagonal lines of red and 
brown. The first Avhorl of the five is discoidal. It is characterized 
by extremely minute wrinkling over the whole surface, only dis- 
cernable under the microscope when quite fresh. The umbilicus is 
very large when young, and sharply keeled ; when adult it is often 
nearly filled up by the callous labium. Operculum radiately 
wrinkled over a large part of the outer surface; within spire \)yo- 
duced, sharply keeled. The largest specimen measures: Alt. '13,

on one side with dark broAvu ; in the other specimen the ground- 
color is brownish rose-red, and the "drops" have united into yellow-

P. iNCONSPicuA Phil., 1853. PI. 39a, fig. 19. 

Shell ovate-conoid, j^^ffarate, very smooth and shining; whorls 
5?, very convex, and rapidly increasing, the last three-fifths of the 
total length ; spire conic, but apical whorl blunt, white ; the following- 
whorls reddish brown, with oblique white brown-bordered flammules 
above, apparently unicolored brown below, excepting a series of 
white flecks around the umbilicus, but upon close inspection showing 
very oblique brown lines as in P. minuta [= tessellata P. et M.] and 
P. perforata. Alt. 5 mill. Habitat unknown. 

From P. minuta and P. perforata it is distinguished by the more 
rapidly increasing whorls, etc; from P. guttata it is separated by the 
umbilical perforation. My description and figure are from Philippi.

"The shell is thin, imperforate, steeple-shaped, acute, smooth and 
very shining, unicolored olive brown. Only a narrow l)order on the 
columella is white. The 7 whorls of which it is composed are but 
slightly convex, especially above; the last attains almost half the 
altitude of the shell; the aperture is ovate, acute above." {Philippi.)

P. brevis Velain (fig. 91) seems to me to be identical ; the name

Var. SUBSTRIATA Carpenter. 

Form as in E. variegata; but whorls, except the nuclear, very 
delicately striate, the last with about ten striae. 

As the name variegata is preoccupied in Phasianella, it would be 
better to use the varietal name, substriata, for this species. 

P. PUNCTATA Carpenter, 1864. Unfigured.

I do not know that this and the following species belong to 
Eucosmia. They resemble that group in the minute size, umbilicate 
base and depressed form. 

P. BREVis d'Orb., 1853. PI. 40, figs. 8, 9. 

Shell short, umbilicate, thin, smooth, white, variously flammulate

obtuse; Avhorls 4, convex; aperture nearly round. Alt. 11 mill. 



The name brevis is several times preoccupied iu Phasianella. l)ut 
not, I believe, for well established species. However if it be deemed 
desirable to avoid this duplication, the present species may be call- 
ed P. brevissima. 

Subgenus Orthomesus Pilsbry, 1888.

tral tooth reduced to a minute rudiment or absent.

pointed, conic; aperture rather small, short ovate, less than half the 
length of shell, widely rounded below, angular above; columella 
with a flattened callus ; parietal Avail more or less Avhite callus, and 
decidedly thickened near the posterior angle ; color variable, usually 
flesh tinted, ashen or broAvn, more or less clouded with darker and 
lighter shades, and flammulate Avith dark and light beloAV the 
sutures, spirally traversed by narrow hair-like li)ies of brown or red 
interrupted by white dots and intervals, the Avhite sometimes pre- 
dominating. Alt. 20-25 mill. 

Zanzibar; Bed Sea ; New Caledonia ; Mauritius, etc. 

Rather variable in coloration, but the narrow lines, — too narroAV 
to be plainly shoAvn in the figures, and difficult to make out Avithout 
a glass — are constant. 

The synonymy is extensive ; including P. nivosa (pi. 38, figs. 49, 
50) P. jaspidea, (fig. 44, 36.) P. lentiginosa (fig. 51.) and P. fulgurata 
(fig. 55) of Reeve, P. grata (pi. 39a, fig. 14), P. splendida (pi. 39rt, 
fig. 5,) of Philippi, P. lineolata Wood, P. viridis Anton, and P. rubens 
Lam.. The latter I cannot identify; but judging from Philippi's 
description and figure (pi. 39a, figs. 6, 7) of Avhat he supposes to be 
Lamarck's species, and from Kiener's, (pi. 38, figs. 47, 48) I Avould 
place it in the synonymy of P. variegata. Philippi giA'es Australia 
as the locality of P. rubens. P. broungniarti Audouiu, (PI. 39, figs. 
63-66) is said to belong here. It is from the Red Sea. 

P. UNiFAsciALis Kieucr. PI. 39, fig. 96.

formed of 5 whorls, not very coua'cx, the last large ; aperture large, 
oval, somcAvhat angulate above; color orange-red, Avith a subsutural 


sharply defined fascia of white and brown flammules, and a similar 
one encircling umbilical region. Alt. 16 mill. 


No narrow revolving lines are noticed in the description of this 
species, nor ar.e they visible in the figure. There are however before 
me specimens which have all the characters of this species, plus 
the capillary lines, and I am inclined to believe it a variety of the 
P. variegata. 

P. FLAMMULATA Phil., 1848. PI. 39a, fig. 9. 

"The shell is jjretty solid, long conoidal, very smooth and very 
shining, and consists of 6 whorls, which are strongly convex and of 
which the last is about three-sevenths the entire length. The aper- 
ture is ovate, [eiforniig] angular and with a little canal above, 
caused by a thickening upon the inner wall, which stops just short 
of the insertion of the outer lip; the coloration, in the numerous 
examples which! have seen, is very constant; it consists of a yellow- 
ish ground-color, merging into olive, with wavy milk-white flames 
which are anteriorly bounded with dark, posteriorly becoming lost 
in the ground-color, and still finer undulating parallel lines showing 
upon the ground color, as well as spiral rows of milk-wkite points, 
which are not connected by brown lineo as in P. lineolata and P. 
splendida. Alt. 12 mill. Ped Sea.

Subfamily Turbinin^. 

Shell turbinate or trochiform, solid, nacreous within, smooth or 
sculptured outside ; operculum circular or elongated, smooth or rug- 
ulose outside. Foot rather short and broad ; epipodial line with 
or without cirrhi. Dentition always according to the formula 

In this subfamily there are three well-marked groups, here con- 
sidered to rank as genera, of perhaps nearly equal systematic value. 
The principal characters upon which this division is based are the 
ojierculum and the radula. The latter is discussed as fully as my 
material permits below. The operculum, in the entire group, com- 
mences as a multispiral disc, like that of a trochus, upon the outer 
side of which is deposited a thin calcareous layer by a lobe of the 
foot which projects partly over it. This arrangement produces an 
operculum which exhibits all the whorls beneath, l)ut which is only 
feebl}', or not obviously spiral above, from the more or less general 
distribution of the calcareous matter. 

In the genus Leptothyra the development does not go beyond the 
primitive stage. The operculum is multispiral, with a thin, calca- 
reous stratum, slightly more prominent around the outer whorl. In 
Turbo the nucleus is the same ; but several more rapidly increasing 
whorls are added, upon which a much heavier layer of calcareous 
material, covering the whole surface, is deposited. In Astralium a 
very rapidly enlarging whorl starts from the multispiral nucleus, 
forming far the greater portion of the operculum, and usually leaving 
a pit at the starting point. 

The radula is broad and generally rather short. Median, lateral 
and marginal teeth are always present, and the formula is invariably 
30 "S'l^'S" 00. The central teeth are always more developed than in 
the Phasianellince, (in which the central tooth represents the part 
here called the body.) l>ut never have the long sen-ate cusps so

frequent in the Trochidce. They are made up of three parts, which 
are lettered on my plate 61, fig. 12; the body of the tooth d, which 
bears the emp, e, when any is present ; this is usually expanded at 
the lateral margins into supporting wings, c, (the "Stutzlamelle" of 
Troschel.) Under it lies the basal plate, a. ("Basalplatte" of 

Between the body and the basal plate there is frequently an 
accessory plate, marked b in the figure, the function of which is 
unknown to me. 

y Genus Turbo. 

A. Central teeth tvithout cusps. 

Turbo, including Seiiectus and Batillus. Troschel has figured 
the radulffi often species of this group including, however, only one 
of tyi)ical Turbo, T.petholatus ; and I have examined those of several 
additional forms. There is but slight variation in the several species, 
and for detailed descriptions of each the student is referred to 
Troschel's work. The median tooth consists of a narrow oblong 
quadrate l)asal plate, frequently with accessory plates of various 
forms, to the lower end of which is attached the oval body of the 
tooth, — a simple plate without cusp, bearing supporting wings at 
the sides. (pi. 61, fig. 6, T. radiatus Gmel.). Frequently the 
central teeth are asymmetrical in this group. The laterals l)ear 
supporting wings at their outer angles, and are various in form, with 
or without cusps ; the inner marginals are very large, with large 
cusps, (pi. 61, fig. 5, T. argijrostomus.) 

Callopoma. Median teeth like those of Turbo; laterals Avith 
simple cusps, and, except the outer one, supporting wings, giving 
the body of the tooth a trigonal form. INIarginals as in Senectiis. 

Nmella. Very similar to Co/^^o^irt in character. (See Troschel) 

Modelia, Ocana. Radula unknown. 

B. Central teeth with cusps. 
Marmorostoma. In this and the following subgenera the central 
teeth have decidedly reflected simple cusps. The lateral margins 
bear supporting wings. Lateral teeth similar, but asymmetrical, 
the outer one without supporting wing; marginals as in Senectns. 
{T. porphyrites, pi. 61, fig. 10.) Additional species are figured l)y 
Troschel. T. smaragdus, which I include in this group, has similar 
teeth, except that the basal plate projects above the cusps of median 
and lateral teeth. 


Sarmatmis. (T. ■sarmaUcus, pi. 61, fig. 7.) This form is peculiar 
in the central teeth, which are composed of three lamellae overlying 
each other; the cusp is wide and simple. Laterals with cusps, and 
basal plates projecting beyond the cusps. Marginals as in Senectus. 

Prisogaster. (T. niger, pi. 61, fig. 9.) Median tooth with a very 
wide body, and supporting wings, cusp narrowly reflected along 
the whole upper margin of the tooth ; laterals with prominent 
cusps, their bases denticulate ; inner marginals not enlarged as in 
the preceding groups, but rather narrow, with long simple cusps; 
outer marginals with long serrate cusps. In the denticulate cusps 
of the lateral teeth, and the narrow inner marginals this form ap- 
proaches more closely than any other to Leptothyra. 

Genus Astralinm. 

A. Central teeth with cusps. 

Astralium, s. str. {A. spinulosum, p\. 61, fig. 12.) The median 
tooth has a long basal plate, a, upon which an accessory obovate 
plate, b rests; upon this is placed the body, d, with ''stiitzlamelle," 
c, and cusp, e. The laterals are provided with cusps, and, except 
the outer two, with supjiorting wings. 

Lithopovia. (A. tuber, pi. 61, fig. 8.) Median teeth as in A. 
americanum, but with the basal plate projecting below. Laterals 
similar, asymmetrical. In A. ccdatum the central teeth are nearly 
as wide at the apex as at the base ; cusp equally wide ; otherwise 
similar in'essential characters. In A. americanum {\>\. 60, fig. 71,) 
the basal plate does not project above the cusp; the tooth is sub- 
triangular, with supporting wings on the sides. 

Imperator. The radula is known only by a figure published by 
Hogg many years ago. The central and lateral teeth bear cusps. 
The marginals are not especially large toward the inside. No 
further characters can be made out from the figure. 

Guildfordia. Radula unknown. 

B. Central teeth ivithout cusps. 
Bolma. Troschel has figured the radula of Jl. rngosa. My own 
preparations show a decidedly different form from his figures ; the 
centrals (pi. 61, fig. 13) have a narrow long basal plate, which is 
produced above the body of the tooth ; the latter is wide, oval, not 
reflected above ; its lower margin is not well-defined in my specimens 
vthich are, however, not stained ; the laterals are of the usual form 
and bear cusps. This group does not seem to be more related to 


Turbo than the other subgenera of Astralium ; I have no hesitation 
in placing it in the division oi Astralium containing species without 
cusps to the central teeth. Compare Troschel, Das Gebiss der 
Schnecken, t. xxi, f. 1. 

Cyclocantha. Troschel has examined the dentition of "A. rhodo- 
stoma." His figures show very nearly the same form that I have 
figured for ^4. Aynericanum, and especially in the central teeth. I 
have examined the radula of only one species, A. plicatospiyiosum, 
and find it of a wholly different form. (PI. 61, fig. 14.) The median 
teeth do not have a basal plate projecting above ; the body is quad- 
rangular, somewhat the shape of a maltese cross, without cusp. The 
laterals have long cusps with spurs at their bases. I am inclined to 
believe that Troschel's figure was drawn from a species of the West 
Indian group of Astralium, not the real Cyclocantha. In view of 
the great discrepancy between his results and my own, it is very de- 
sirable that additional species of Cyclocantha be examined. 
Uvanilla. Radula unknown. 

Cookia. My knowledge of the radula of this form is derived from 
a figure and description given by Hutton. Median tooth with a 
long basal plate and short body, of the general form shown on pi. 61, 
fig. 11 for Pomaulax. It bears no cusp, and has small supporting 
wings. The first lateral also is much like that shown in Pomaulax; 
the others bear cusps, and, except the outer, have ''stutzlamelle." 
Inner marginal very broad, with wide cusp. Cusps of outer mar- 
ginals simple. 

Pomaulax. (pi. 61, fig. 11.) In ^4. undosum I find much the same 
type of dentition as Hutton has figured for Cookia. The median 
teeth have long basal plates, and a cuspless body, with its lateral 
margins produced into supporting wings. The inner lateral is quite 
complex in structure ; its upper edge is not reflected, but seems 
turned upward somewhat ; its outer upper angle, a, lies under, and 
its supporting wing ("Stiltzlamelle "), b, over the succeeding lateral 
tooth. The three following laterals have the same form of body, 
but their apices bear broad simple cusps ; the outer lateral is narrow, 
with a bidentate cusp. The marginals offer no unusual characters ; 
the inner ones are large, with long cusps denticulate at their bases ; 
the outer ones have serrate margins. 

Pachypoma. Median tooth with a narrow basal plate, projecting 
above a rectangular simple accessory plate, which l^ears about the 
middle the oval body, without cusp, but with the sides produced into 


supporting wings. Laterals narrow, with simple cusps and supporting 
wings, the outer narrower and with bidentate cusp. Inner marginals 
with very large cusps. (See Troschel.) 

Genus Leptothyra. 

I have examined the dentition of the following species : L. car- 
penteri, (pi. 60, fig. 73,) L. bacii/a, L. kcia, L. aviussittata, L. sangaren- 
sis, (pi. 61, fig. 15) L. granulosa. In all of these species the median 
teeth are oval, wide, with a narrow projection above, and more or 
less narrowed toward the base ; the u]>per margin is in no case re- 
flected, so that cusp, cutting point or edge, in any usual sense, there is 
none. In L. carpenter'i and L. hacula, however, there is a ledge or 
thickening, more or less irregular on its lower raai'gin, extending 
across the body near its upper margin ; but this is not formed by a re- 
flection of that margin, and so cannot be considered as a cusp ; in the 
other species this structure is absent. The lateral margins are pro- 
duced into supporting wings. The laterals are long, excavated on 
the inner side for the reception of the supporting wings of the cen- 
trals, and with a process, b, underlying these supporting wings. 
Their outer margins are produced into supporting wings like those 
of the centrals. The cusps are provided wdth several minute denti- 
cles at their outer bases. All of the laterals are of this form, except 
the outer ones which have no supporting wings. The marginals are 
armed with long blunt narrow cusps, which are longest on the teeth 
about the sixth from the inside, and decrease in size in either direc- 
tion from that point ; about the twelfth from the inside their margins 
begin to become serrate. It will be seen that my results are very 
different from those obtained by Troschel, who has figured the rad- 
ula of /j. carpenteri (under the name of "L. coccineus Desh."). I am 
constrained to believe that, owing probably to some imperfection in 
his preparation or other cause, he misinterpreted certain structures 
of these minute radulje. The characters of the radula lend no sup- 
port to the opinion expressed by some authors as to the position of 
this genus in the Trochidce ; but it is not very closely allied to any 
group- of the Turbinida'. I am undecided about the nature of the 
projection from the upper margin of the central tooth of Leptothyra ; 
it may be homologous with the basal plate of the j)receding groups ; 
but if so it seems to be united with the body as far as the upper 
margin of the latter, — a condition which is not found in Turbo, etc. 

In concluding this review, I wish to direct the attention of con- 
chologists to the desirability of procuring and examining the radula; 


of those subgenera in which tliis organ is unknown, in order that 
their correct systematic position may be confirmed. More especially 
is it necessary that in the cases of Cyclocantha and other groups 
where the testimony of different observers is considerably at variance, 
additional species be investigated. 

In the following account of the various species, subgenera and 
genera of this family, I have taken every care to adopt a nomencla- 
ture that wall prove stable ; deviating in many instances from the 
usage of previous authors upon this family in oi'der to attain this 
end. Notably is this the case in certain subgenera of Astralium, in 
which the pernicious practice followed by many systeniatists of select- 
ing Avhat they believe to be a " natural " type for a group, instead of 
restricting the group to species with the organization of the " histor- 
ical " type, has led in some instances to the exclusion from a subgenus 
of the very species designated by the describer of that group as its 
type ! I have quoted polynomial or "historical" synonymy only in 
cases in which such names have been ado]) ted into general use. 

In describing sculpture, I have usually avoided the use of the term 
" transverse," because there seems to be considerable confusion in the 
minds of many as to whether such sculpture is transverse to the 
whorls or to the axis of the shell. The term " longitudinal " is here 
used to designate markings parallel to the axis, and "spiral" to de- 
note such as follow the direction of the whorls ; in flattened species 
the former is frequently designated as " radiating," and the latter as 
" concentric." 

The Turbines have an old and extensive literature. Most of the 
niore prominent species were figured by Chemnitz, and before him 
by Lister, Rumphius, Knorr, and many another quaint old author, 
whose tomes now stand undisturbed on our library shelves, as per- 
haps our own will rest a century hence. From these store-houses 
Linnseus drew freely in his mammoth task of cataloguing all animate 
nature, fitting the species defined by previous authors into his Systema 
with no other addition than a binomial aj^peilation. 

In modern times each of the four princij^al monographic works 
have considered this group :

inside, with three or four whorls and subcentral (multispiral) 
nucleus; outside convex, smooth, tuberculate, or with concentric 

The diversity of forms of both shell and operculum in this genus 
is very great, and has caused the formation of numerous subgenera. 
The affinities of the minor groups I have attempted to express in 
the following table :

Indo-Pacific Provivce. 

Synonyms: Olearia Klein, Senectus Swainson. 

Three subdivisions may be distinguished, diflferiug in unimportant 
characters: Turbo, (restricted), shell large, dilated at base, imperfor- 
ate; whorls smooth or nodulous. Senectus (Humph.) Swainson, 
shell generally perforate; whorls spirally lirate. Batillus ^cXwvoa., 
shell inflated, imperforate ; whorls spinose ; operculum with a convex 
spiral rib outside. The dentition is essentially the same in all. 

T. MARMORATus Linn., 1758. PL 41, flg. 23. 

Shell large, imperforate, solid, ventricose, as broad as long, green, 
marbled with white and rich brown; whorls 6-7 flattened or con- 
cave above, rounded and bearing two nodose keels below, and a

stronger nodose carina above; aperture large, pearly within, base 
produced, columellar region more or less excavated. Alt. 100-200 
mill. Indian Ocean; Philippines; Seychelles; Japan, etc. 

T. regenfussiVhW., not Desli., and T. olearius Gmel. are synonyms. 

Operculum (PI. 59, fig, 21 ) subcircular, somewhat concave within, 
exterior closely tuberculate, whitish. 

T. iMPERiALis Gmel, 1788. PI. 43, fig. 53; PI. 62, fig. 8. 

Shell large, globose-conic, ventricose, imperforate, solid, green, 
irregularly mottled and spirally striped with chestnut, closely 
irregularly striate with the same color; whorls 6-7 convex, with 
well marked sutures, and numerous more or less conspicuous revolv- 
ing furrows; last whorl large, somewhat flattened above; aperture 
subcircular, pearly white within; outer lip rather thin; columella 
arched, with a pearly callus, which reappears at the posterior angle; 
parietal wall nearly devoid of callus, green ; base slightly dilated, 
scarcely produced. Alt. 75-100, diam. 70-90 mill. 

Indian Ocean ; China Se<(S. 

Most specimens have less prominent i*evolviug wrinkles than the 
figure, and some occur almost smooth. Perhaps Reeve's figure, 
copied in my fig. 53, is a form of T. marmoratus. 

Operculum circular, flat inside, with four whorls and subcentral 
nucleus; outside convex, partly granulose, pale brownish olive. 

T.VouRDANi Kiener, 1839. PI. 49, fig. 53. 

Shell large, ovate-conic, solid, imperforate; epidermis castaneous 
or olive ; spire acute ; whorls 8, rounded, regularly increasing, the 
upper ones 1-3-carinate, the lower transversely obsoletely lirate, 
the last large, ventricose, descending, nearly smooth, or with wide 
spiral cost?e; aperture circular, white within, outer lip thin, colu- 
mella arcuate, not expanded at base. Alt. 140-210, diam. 110-170 
mill. Australia. 

T. MAGNiFicus Jonas, 1844. PI. 40, fig. 13. 

Shell ovate-conic, turgid, imperforate, brownish, maculated and 
marbled with violaceous; whorls 6, rounded, finely transversely 
striate, the upper ones obscurely ungulate in the middle, the last 
obtuse; spire a little exserted, suture distinct, linear; aperture large, 
circular, pearly within, opaque at margin ; columella cylindrical,

TURBO. 193 

T. CEPOiDES E. A. Smith, 1880. PI. 44, fig. 78. 

Shell ovate-conic, narrowly but profoundly perforate, pale brown, 
strigate with green variegated with white ; whorls 7, very convex, 
slightly compressed or sub-excavated above, with conspicuous irreg- 
ular sub-lamellose incremental striae and inconspicuous spiral lines 
and sulci above; aperture almost circular, slightly shorter than the 
spire, inside pale salmon, pearly. Alt. 80, diam. 70 mill. 

Habitat unknown. 

This «ipecies seems to be most nearly allied to T. iinperialis and 
T. jourdani. Smith compares it to T. magnificus Jonas, and says 
that it is distinguished from that form by the presence of a deep 
perforation, the narrow sulcations revolving around the upper part 
of the whoi'ls, and by the coloration. 

T. EEGENFUSSi Desh., 1843. PI. 48, fig. 40. 

Shell ovate-conic, thick, imjoerfbrate, whorls 5-6, smooth, convex, 
the last large, dilated, veutricose, angulate above, with a revolving 
series of more or less prominent tubercles, below rounded ; aperture 
circular, inside pearly; peristome simple, posterior angle with a 
thick callus, columella arcuate, not produced at base ; color vivid 
green, variegated with spiral series of square alternating white and 
deep chestnut maculations. Alt. 84, diam. 80 mill. 

Indian Ocean. 

Operculum as in T. imperlalis, reddish and granulose without. 

I am not at all certain that the figures cited by Deshayes do not 
represent a form of T. marmoratm; they are more produced at the 
base than the figure given by Fischer (and which I have copied) 
indicates. It may prove to be a variety of T. marmoratiis. 

T. PETHOLATus Linn., 1758. PI. 40, ng. 14. 

Shell imperforate, solid, polished, shining, rich brown, variously 
ornamented with dark bands interrupted with white blotches and 
narrow stripes; whorls 5, flattened beneath the suture, sometimes 
carinated above ; aperture about half the length of the shell, circular, 
pearly within ; peristome and columella tinged with greenish-yellow,

Shell large, ovate-conic, heavy, solid, imperforate ; dirty white, or 
greenish, maculated with angular, alternating blackish or brown and 
lio-ht patches on the broad flat spiral ribs, the interstices narrow, 
superficial, whitish ; whorls 6, convex, more or less prominently 
shouldered above ; ribs obsolete around the axis ; aperture white 
within, over half the length of shell, ovate, angled posteriorly and 
at position of carina; its margin more or less green tinged, not 
fluted ; columella thickened and effiise at base, callous posteriorly. 

Alt. 80, diam. i^o mill. N. Australia; New Caledonia, etc. 

T. canal icidatus of Kiener, (PI. 47, fig. 21) and of Reeve (PI. 42, 
fig. 45), and T. psittacinus Phil.? are synonyms. 

Operculum (pi. 59, fig. 32) subcircular, concave internally, with 
nucleus one-third the distance across face; outside very convex,

ulate or tessellate with dark ; whorls 6, convex, rounded, more or 
less angular around the upper part, with inconspicuous incremental 
striifi and revolving lirse, which on last whorl are wide and flattened 
with narrow interstices and are obsolete around the axis ; aperture 
over half the length of shell ; white within, oval, angular above and 
below; peristome scarcely crenulated, frequently greenish ; columella 
with a heavy white callus, dilated and eff^use at base. Alt. 80 mill 

EaM Indies. 

Operculum (as figured by Gould) green outside. 

T. canaliculatm Gniel. is probably this species. It cannot be de- 
termined with certainty. It is T. margaritaceus of Kiener. 

TURBO. 195 

I am inclined to believe that T. sparverius is a variety of T. a-as- 
SKS. Both are separated from T. setosus and its allies by the ol)so- 
lesceuee of the spiral lirpe around the axis. 

T. SETOSUS Gmel., 1788. PI. 63, fig. 32.

I have not seen this form, which Fischer compares with setosus 
und artensis. In coloration it is similar to T. fluctuosus ; and Car- 
penter has identified it with doubt with that species. 

T. JAPONicus Reeve, 1848. PI. 44, fig. 81 ; PI. 48, fig. 41. 

"Shell ovate, imperforated, rather thin, somewhat inflated; whorls 
smooth, spirally ribbed, ribs sometimes prominent and regulai", some- 
times rather flattened and very irregular; fawn-yellow, variously 
stained and blotched with red, interior silvered." (Reeve.) 

Reeve confounded two forms in his illustrations and diagnosis of 
this species: One of his figures, (pi. ix, fig. 336. of the Conchologia 
Iconica) is the young of T. cornidus Ginel.; the other, (pi. viii, fig. 
33, of the Iconica) precedes this on his plates, and has been recogni- 
zed by Kiener and by Fischer as the real T. Jajwnieus. Under these 
circumstances I am compelled to place in the synonymy Sowerby's 
T. reriiiciis, which he founds upon shells which are (teste Sowerby, 
Thes. Cb?zc/(., p. 197.) identical with Reeve's first figure of T.japoni- 
cus. According to Sowerby the species is from Mauritius, not Ja])aii. 
The following is Sowerby's description.

T. cernicns Sowerby, 1886, (pi. 44, fig. 81,) "Shell ovate conic,

above, minutely obliquely striate, encircled by wide flattened ribs, 
alternating with smaller ; last whorl obtusely angulated above, 
lightly depressed above the angle, scarcely canaliculate ; aperture 
circular, lip acute, scalloped; columella thick, convex, slightly 
arcuate and slightly produced at base, longitudinally plicated." 

"Operculum very convex outside, green, sufi^used with bright 
reddish-brown, conspicuously granulose." Sowerby's figure, copied 
on my plate, is two-thirds natural size. 

Specimens before me from Mauritius, of this species, are rather 
smaller than Reeve's figure ; the broad flat ribs, apd brown opercu- 
lum, conspicuously granulose in the middle, are the more prominent

A very variable species. I have seen many imperforate and sub- 
perforate specimens otherwise typical in character. The lirse are 
sometimes subequal and nearly smooth ; this form is the T. margarita-

Philippine Is. (Philippi.) 

It is the Delphinula turbinopsis of Lamarck ; T. lamarckii Phil, 
is a synonymy. 

With the exception of Philippi whose identification is doubtful, 
no one, in recent times, has seen this form. 

T. LAjONKAiRii Desh., 1839. PI. 49, fig. 42. 

Shell large, turbinate, solid, umbilicate, white, sometimes sparsely 
maculate with chestnut; whorls 6, striate, spii'ally lirate, bicarinate, 
the last one and one-half armed with erect long stout tubular spines 
on the carime, ten to twelve in number on the last whorl, usually 
tinged with green ; apertui-e ovate, pearly white and iridescent 
within; columella thickened below, deflexed, produced and some- 
what channelled, excavated at the conspicuous umbilicus. Alt. 80,

four whorls and subcentral nucleus ; outside convex, coarsely granose,

toward edges, margin sub-striate, with an orange line. 

This species is most nearly allied to T. argyrostomus, differing in 
the greater developn)ent of spines and the wider umbilicus. The 
spines first appear as vaulted scales upon the upper carina; only in 
well grown specimens do they become closed in front into tubes.

Under the above specific name I unite a number of nominal spe-

are T. speciosus Kiener, (pi. 47, fig. 24) T. spinosus Grael. et auct., 
T. tuberculatus Kiener, T. chemnitzianus Reeve — founded upon the 
same figure cited by Gmelin for T. radiatus — T. nivosus Reeve, (pi.

This is not the T. radiatus of Reeve nor of Kiener, nor (probably) 
of Anton.

aperture round, produced into a projecting angle posteriorly and 
frequently disconnected from the body-whorl, white and pearly with-

Philippines; New Caledonia; Seychelles ; Madagascar; Singapore, etc. 

Operculum (pi. 60, fig. 47, 49,) with four whorls and subcentral nu- 
cleus ; outside very convex, deep green, olive or brownish in the 
centre, lighter toward the margins, all over except side of increment 
finely granulose, and with a radial sulcus marking the limit of the 
margin of increment. The prominent character of the operculum 
in this species, as well as in T. foliaceus etc., is the manner in which 
the outer layer of calcareus matter overlies tlie granulose surface 
below, with an obvious sulcus at their junction. PI. 60, fig. 38, is 
the operculum of the form known as T. tiimidubis Rve. 

The following are synonyms: T. radiatus Kiener (in part), T. 
tumidiilus Reeve. This species is closely related to T. intereostalis 
Mke., but differs in color, in tlue greater prominence of the ribs, and 
in the operculum. My description and figure of the operculum of 
ticaonicHS are drawn from alcoholic specimens containing the animal. 
T. foliaceus Phil, is also allied, and has similar operculum, but has 
much more conspicuous incremental lamella?. The umbilicus is in- 
differently perforate or closed, sometimes rather wide, and the 
variation in sculpture is considerable. T. jmlcJier Reeve is separated 
from this species principally because, according to Sowerby, its oper- 
culum is different. I suspect however that he is mistaken in this, 
and that it will prove to l)e the same; pulcher is the prior name.

it a form of T. castaneiis, although I have seen no specimen of that

This is undoubtedly the cochlea liinaris moltkiana etc. of Chemnitz,

This handsome Senedus is more closely allied to T. Jilosus than to 
any other known species. The general form and proportions are 
the same , but the beautifully beaded lirse and especially the almost 
perfectly oval aperture will separate it from that species. In color, 
too, the forms are diverse. The parietal callus is not shaped like 
that of T. Jilosus, nor is the columella below so broadly everted and 
lipped as in that species. The anterior outline of the callus, from 
the base to the superior angle of the aperture, is wholly diflferent in 
the two species. The sculpture and columella will separate this 
form from T. spencjlerianus, w^hich, with heterodiellas and jilosus 
form a group of species, lying on the outskirts of Senectus, the more 
prominent characters of which are found in the peculiar parietal 
callus and the operculum Avhich exhil)its a feebly spiral structure

T. japonicus Reeve, in part, (pi. 43, fig. 52) is synonymous. 

The lower series of spines is sometimes absent.

The afl&nities of this group are with Ninella on the one hand and 
Senectus on the other. In the latter group, the opercula of T. speng- 
lerianus and T. cornutus show some affinity to those of Callopoma.

Shell much more depressed than the type. 


Carpenter cites Reeve's pi. viii, fig. 34 as representing his variety; 
but that figure is of the common form. Reeve's fig. 3c on pi. ix, is 
probably what Carpenter intended.

212 TURBO. 

An extremely variable species. Frequently several tuberculate 
lirse encircle the base ; and in this strongly nodose variety the in- 
cremental striae are usually inconspicuous. In another form the 
spiral lirse are not noticably tuberculate.

The above description, (copied from Proc. Linn. Soe. X. S. ]Vales 
ix, p. 355) is all the information I can give regarding this species. 
The copy of Hutton's "Catalogue of Marine Mollusca of New 
Zealand" to which I have access is without the signature containing 
his description. The operculum is unknown. Hutton places it with 
doubt in Ccdlopoma, probably not its correct position. 

Subgenus Ninella Gray, 1850.

inate. Operculum oval, nucleus excentric ; outside concave in the 
middle, with two strong spiral ribs, the outer margin thin, granulate.

This species varies much in degree of elevation and carination. 
It merges by insensible degrees into the var. lamellosus. In the 
typical form the sutures are frequently simple, not canaliculate, and 
the subsutural tubercles are wanting.

"T. rubicundits Chemnitz" of authors is a synonym. 

This species was first figured by Chemnitz in 1781 under the des- 
criptive name of cochlea lioiaris ruhicunda granosa etc. Reeve in 
his Conch. Syst. figures the shell, naming it T. rubicnndus, and re- 
ferring to P. Z. S., 1842, for description. His reference has been 
copied by subsequent authors, but curiously enough, the species is 
not even mentioned in the "Proceedings," for 1842 or any other year. 
Martyn's figure is excellent, and being the first publication of the 
species under a binominal name, has been here adopted.

T. (jruneri Phil. (pi. 56, fig. 82) is a synonym. 

There is some uncertainty about which of the above names has 
priority for this species. The volume of the Conchylien Cabinet in 
which Philippi's description occurs, bears date of 1846 ; but it was 
not completed until after the publication of Reeve's monograph of 
Turbo in the Iconica. Philippi begins to cite Reeve in his synonymy 
on p. 69 of his Avork, so that from that point onward we may be 
certain that his work appeared subsequent to Reeve's; but whether 
liis description of T. gntneri (p. 52 of the Couch. Cab.) Avas actually 
j)ublished before Reeve'.s description I am unable to decide. Brazier 

TURBO. 215 

(Trans. Roy. Boc. S. Australia, ix, p. 125) gives priority to gruneri,

The operculum is unknown to me; the species may perhaps be 
found to group elsewhere.

excavated or callous; broad, somewhat flattened below the deep 
narrow umbilicus, dilated and produced or rostrate at base.

obsoletely granulose, nearly smooth. 

This is T. versicolor, mespilus, ludus and porj^hyrites Gmel. T. 
lugubris Kiener (PI. 50, fig. 57). T. versicolor Rve. (pi. 42, fig. 39,) 
is somewhat intermediate between porjihyrites and porcatus. 

T. mespilus is said by Fischer to be thinner, more uniform in 
color, more rostrate at base, last whorl more descending; but all the 
characters are so variable that I cannot draw the line between the 
several forms.

made by imperceptible degrees. 

Var. GRANULATUS Gmel, 1788. PI. 46, fig. 18. 

Shell typically more elongated than T. coronatus, altitude about 
equalling the diameter ; umbilicate, finely granulose all over, with

It is T. helicinus Born, 1780. This name has precedence over 
Martyn's ; but I doubt the expediency of changing the w'ell-known 
name at this late day. I am not sure that the species belongs in 
Marmorostoma, but it certainly should not be placed in Turbo ss. as 
is usually done.

The synonyms are Calear (Montf.) Fischer and other authors, 
Imperator (Montf) Auct., Trochus, in part, of all earlier authors, 
and Tarho, in part, Sowerby Jr. and others. 

Authors have been consideral)ly at variance in regard to both 
the limits and the proper designation of this genus. I have exam- 
ined the history of every name proposed for species of the group, 
either as generic or subgeneric, and find that none prior in date to 
that of Link (1807) are entitled to any standing in nomenclature, 

I am indebted to Dr. W. H. Dall for a copy of Link's description 
of Astralium. It was defined in the Beschreihung der Naturlien- 
Sammlnng der Universitdt zii Rostock, von D. H. F. Link, Professor, 
etc., p. 134-135, May 17, 1807 ; the genus is briefly described by 
Link and ^4. deplanoium given as the first species, with a reference 
to figures in Chemnitz, which fix the identity of deplanatmn with 
Lamarck's A. costulatum, a species of the West Indian group. 

Those species having a turbinate form, convex base and rounded 
periphery, such as ^4. rugosum, A. cwlatinn, A. tuber, have been 
frequently adduced by authors as supplying the connecting links 
between Turbo and Astralium ; but such resemblance as they have 
to Turbo is to be attributed not to any real relationship, but to a 
secondary modification which they have undergone from the stellate 
forms of Astralium. That this is the case is shown by the young of 
the turbinate species, Avhich we find to be flattened, acutely carinated 
and spinose, precisely as in typical Astralium. As a rule, the young 
of species of this genus are depressed, carinated and spinose at the 
periphery, the sjiines frequently being reduced in size or lost in the 
adult ; whilst in Turbo the young are in the spinose species smoother 
than the adult, the spines becoming always more prominent with age. 

The real connecting forms between these genera the student must 
look to palaeontology to supply; for the recent species which at first 
seem to be intermediate in characters are undoubtedly descending 
from stellate types of Astralium. 



Like Turbo, this geiuis is composed of a number of quite diverse 
subgenera of various degrees of affinity to each other. I am in- 
clined to divide them first into two series : those with the central 
teeth of the radula composed of several plates overlying each other, 
and without a reflected cusp at the superior margin, and those with 
a reflected cusp above. The natural sequence and affinities of the 
subgenera are sliown in the following table :

perforate, carinate at the periphery, base planulate or convex, whorls 
above flattened or concave, costate or tuberculate ; operculum oval, 
outside smooth or nearly so, very convex, excavated near the center. 

West Indian Province. 
Calcar Schum., 1817, is a synonym. 

A. LONGispiNA Lam., 1822. PI. 51, figs. 1-9. 

Shell depressed conic or lens-shaped, umbilicate or imperforate ; 
Avhite, yellowish or light brown ; apex obtuse ; whorls o-Q, acutely 
carinated at periphery, concavely flattened above, obliquely plicate 
or spirally Urate, the lirse bearing tubercles or squamose processes ; 
periphery armed with recurved triangular obliquely wrinkled spines, 
usually thirteen to eighteen in number on the last whorl, and more 
or less projecting at the sutures ; base gently convex, densely laniel- 
lose radiately striate, and with about four concentric subnodose lira3 ; 
aperture transversely ovate, angled and canaliculate at termination 
of carina ; columella short, curved, somewhat dilated over the slight- 
ly indented umbilical tract ; umbilicus generally very narrow or not 
perforated. Alt. 30, diam. 65 mill. 

Entire West Indies; Bahamas; Bermuda; Tbrf tty as (Simpson) ; 



Operculum (pi. oO, i^g^. 57, 58) oval, nucleus sublateral ; outside

near the center. 

Trochus orichalceus (figs. 8, 9) T. aster, and T. heliucus Phil., T. 
planus (Gm.) Phil., Astmlium deplanatum Link and perhaps T. 
inermis Gniel. are synonymous. 

An abundant and variable sjjecies. Figs. 1, 2, represent the typ- 
ical form. The following variety has typically a very distinct as- 
l)ect; but I am unable to separate it specifically by constant or 
well marked characters. 

Var. spiNULosuM, Lam., 1822. PI. 51, figs. 4-6. 

Shell conically elevated, imperforate ; whorls flattened above, ra- 
diately costulate or spirally lirate, or both, and tuberculate or squa- 
mose ; peripheral carina generally subspinose or nodose ; concentric

Two specimens measure as follows : 

Alt. 32, diam. 61 mill ; alt. 38, diam. 45 mill. 

W. Indies; Florida. 

Fig. 6 is drawn from a specimen from Key West, Florida, collec- 
ted by Hemphill. Lamark's T. costulatus (pi. 51, fig. 7), is in form 
intermediate between typical longispina and var. spinulosum; it is 
umbilicate and obliquely plicate above. I cannot tell what species 
Reeve figured as T. spinttlosus ; it seems to be a very depressed form 
of A. petrosum Mart. It is certainly not the spinulosum of Lamarck. 

A. ARMATUM Phil, 1848. PI. 51, figs. 10, 11. 

Shell conic, apex acute ; sculpture as in var. spjinnlosum.

from St. Croix. From that species it diflTers in the conical acute apex. 
A. BREVispiNA Lam., 1822. PI. 52, figs. 12, 13. 

Shell conic, imperforate, solid ; whorls 6-7, flat above, obliquely 
costate below the sutures, then with several revolving series of gran- 
ules; periphery sharply carinate, armed w'ith short triangular spines 
which festoon the sutures and project more or less, about 10-13 
in number on the last whorl ; base a little rounded, radiately lamel- 
lose striate and concentrically lirate, the liras three to five in num- 
ber, mostly tuberculate, especially in the young ; aperture transverse, 
oval, channelled at outer angle ; columella short, arched ; place of 


the umbilicus excavated, whitish, bounded by an intensely orange- 
vermillion tract. Alt. 28, diam. 40 mill.

Shell imperforate, conic, greenish, brown maculated ; whorls 7, 
subplanate, obliquely costulate below the sutures, then with two 
beaded spiral lirae ; margins of whorls exserted, expanded, com- 
pressed, armed with triangular spines ; last whorl sharply carinate ;

Operculum oval, outside white, smooth, with a single arcuate 
wide rib ; inside flat, chestnut colored, nucleus submai'ginal. 

T. huschi Kiener, and T. tentorium Anton are synonyms. 

This form I have not satisfactorily identified with any shells I 
have seen. It seems to be closely allied to the preceding species. 

Subgenus Lithopoma Gray, 1850. 

Shell turbinate or trochifonn, elevated, imperforate, periphery^ 
carinated or rounded, whorls above radiately plicate ; oj^erculuni

green, radiately maculated with brown above, irregularly marked 
and lighter below ; whorls 6, upper two smooth by erosion, the fol- 
lowing obliquely coarsely plicate and finely wrinkled in the same 
direction above, somewhat shouldered, obtusely angular near per- 
iphery, above which several obscure beaded lirse revolve, shagreeii- 
ed by intersection of incremental strise and oblique wrinkles ; base 
nearly smooth ; aperture very oblique, oval, silvery within ; colu- 
mella short, wide, generally bituberculate at the base, exca;vated 
over the location of the umbilicus. Alt. 45, diam. 50 mill.

Operculum (pi. 60, figs. 42, 43) oval, nucleus submarginal ; out- 
side white, excavated around the upper edge, with a heavy coarsely 
grauulose rib following the central part of the spiral, its ends con- 
nected by a short rib.

of authors. 

B. Conic species, with carinated lyeriphery and flattened base. 

In this section of Lithopoma the species are very variable, and it 
is difficult to find characters salient enough to satisfactorily sepa- 
rate several of them. Much more material than I have before me 
must be studied before the synonymy and limits of the various 
forms can be settled. 

A. AMERicANUM Gmel., 1788. PI. 52, figs. 18-20. 

Shell trochiform, elevated, imperforate, solid, white or yellowish ; 
Avhorls 7, the upper three smooth in adults by erosion of the sculpt- 
ure, flattened or concave on their upper surfaces, longitudinally 
obliquely plicate, the folds numbering about thirty-six on the last 
whorl, terminating on the periphery in nodules (or spines in the 
young,) generally intersected about the middle by two to four spiral 
impressed lines, periphery angled, more or less swollen ; base nearly 
flat, more or less sharply radiately striate, and spirally lirate, the 
lirse about six in number, or sometimes more, frequently nodulose ;

eral nucleus ; outside convex, white, granulose, more or less excava- 
ted around the upper margin, excavated near the center ; young with 
a stout curved central rib following the spiral, its ends connected 
by a short straight rib.

Shell elevated-conic, imperforate, solid, wdiitish or pale j'ellow ; 
whorls 7, upper two smooth by erosion, sutures moderately impress- 
ed ; whorls flattened above, longitudinally coarsely plicate, nodulous 
on the ijeripheiy, the folds about twenty-two to twenty-eight in num- 
ber on the last whorl, cut about the middle by a lew spiral impress- 
ed lines ; base slightly convex, concentrically Urate, and radiately 
densely striate, the lira3 about six in number, sometimes nodose ;

diately plicate cordon. Alt. 38, diam. 35 mill. 

West Indies ; Tortugas (Simj^son). 

Operculum (pi. 60, fig. 48) with a strong central spiral granular 
rib, with Its terminations joined by a short riblet, the interval be- 
tween them deeply excavated. 

Allied to A. amerlcanum, but separated by the more decidedly 
granulate and ribbed operculum, which resembles closely that of A. 
olfersii. The peripheral nodes are less numerous than in A. amer- 
ieanum, and more numerous than in A. olfersii. 

A. PAPiLLATUM Potiez et Michaud, 1838. PL 52, figs. 14-17. 

Shell conic, elevated, imperforate, solid greenish-olivaceous, ob- 
scurely banded, spire acute ; wdiorls 7, nearly flat, slightly excavated in 
the middle, finely obliquely striate and radiately costate, folds wdiite, 
oblique, slightly prominent above, at. the peripher)^ tuberculose ; last 
whorl carinated, with about fourteen short tubercles on the carina ; 
base a little convex, radiately striate, with five concentric subnodose 
lira? separated by very shallow grooves ; aperture transverse ; colu- 
mella arcuate, bituberculate at the base ; umbilical tract bounded 
by a plicate cordon. Alt. 25, diam. 29 mill. 

West Lidies. 

Operculum nearly like that of A. cuhanum. 

Figs. 16, 17 are from the original ones of Potiez and Michaud. 

The species is nearly allied to A. cuhanum, perhaps identical. 


A. GUADALOUPENSE Crosse, 1865. PI. 53, figs. 43-45.

ly crinkled, reddish orange, marked in places "with white and oli- 
vaceous ;sutnre impressed, irregular ; whorls 6j, subplauulate above, 
slightly concave in the middle, the apical one or two smooth, the 
following longitudinally plicate, the folds cut in the middle by two 
impressed spiral lines, projecting at the carinated jieriphery, and 
about twenty-three in number on the body-whorl ; base nearly flat 
with radiating stripe and five subgranose liras ; aperture oblique, 
rliomboidal, columella white, arcuate, bidentate at base, umbilical 
tract pale violaceous, bounded by a plicate cordon. 

Alt. 23i diam. 25 mill. 

Guadaloupe, West Indies. 

Operculum outside convex, with a median rib, minutely granulose,. 
excavated near the middle. 

It is closely allied to A. papillaiHm P. & INT., but may be separa- 
ted by the flatter base and perhaps the number of the basal lirse. 
Compare also A cnbcuium. In the only specimen of this species I 
have seen (fig. 45) the peripheral tubercles number twenty on the 
body- whorl. I believe that this species will be found to be a form 
of ^. euhanun or A. jmpillatuvi. 

A. OLFERSiTroschel, (18 ?). PI. 57, figs. 47-49. 

Shell imperforate, solid, conic, gray, olive-green and reddish brown; 
longitudinally plicate, the folds about thirteen in number on the last 
whorl ; periphery nodulose ; base slightly convex, with four concen- 
tric lirse ; aperture subtrapezoidal, white ; columella arcuate, bitu- 
berculate at the base. Alt. 45, diam. 52 mill. 

Brazil (Philippi); Bakia (Clery). 

Figs. 48, 49 are drawn from the original ones. I have seen no 
specimen corresponding with them. The variety figured by Kiener 
(pi. 57, fig. 47) scarcely looks the same to me. It differs in the "less 
oblique ^ud more numerous longitudinal folds, which are more in- 
terrupted about the middle and more nodulose above." A specimen 
of this variety before me is marked "West Indies.'^

sharply carinate peri23hery into squamose square soniewhat descend- 
ing spines ; base flattened, radiately striate, and with four to six 
concentric irregular subnodose lirre ; aperture very oblique, wide : 
lip scalloped, chanelled at outer angle ; columella bidentate below, 
its face slightly grooved. Alt. 40, diam. 45 mill.

T. corolkt Reeve is synonymous. 

A. TUBEROSUM Phil. PL 64, figs. 57, 58. 

This thick-shelled Trochid stands near to T. ccelatus, but is distin- 
guished by the following characters ; the whorls are flat, not arched, 
in the middle ; the superior nodules are situated near to the suture, 
are hemi-sphserical and solid ; the last whorl has but a single row of 
nodules ; the carina is sharper, the base flatter, with only three con- 
centric nodose lirse ; the aperture is lower, more rhomboidal ; color 
reddish brown, more or less vei'ging on violet. 

Coast of Mexico. 

I have translated from Philippi the more important portion of his 
description. I am unable to identify the form with any shells I have 
seen. It is 2:)robably immature.

Shell strictly conic, imperforate, yellowish white ; whorls planu- 
late, the last acutely angled, obliquely plicate, the folds small, about 
forty in number on the body-whorl, interrupted by two spiral fur- 
rows, of which the upper is in middle of the Avhorl, the lower midway 
between that and the wavy lower margin of the whorl ; base nearly 
flat, with six strong, elevated concentric lirse, and radiating lamel- 
lose strise, Alt. 23, diam. 25 mill.

Mediterranean and Japanese Seas. 

Tubicanthus Swains., 1840, is a synonym. 

In the Mollusca of the Challenger, p. 131, Watson corrects the 
orthography of this name, making it Bollna. But I find that Gray 
and authors generally have not deviated from the orthography of 
Risso. (see Hist. Nat. de I'Europe mh-ldionale iv, p. 117). 

A. RUGOSUM Linn., 1767. PI. 40, fig. 20 ; pi. m, fig. 85.

Philippine Is. 

Calcar turcicus (Rve.) Fischer is the same. 

Reeve's figure and description are copied above. Of this form 
Mr. E. A. Smith says : 

This beautiful species is well characterized by its style of paint- 
ing. It is whitish with broad scarlet rays, particularly distinct on 
the sloping upper surfaces of the whorls; these are sometimes 
edged with black posteriorly, and the suture is more or less stained 
■with that color. The lower part of the body-whorl is for the most 
part scarlet with a few narrow white streaks (sometimes black-spot- 
ted) radiating from the umbilicial region. The o])erculum is white, 
thick, convex, and granose externally. (Zool. Coll. H. M. S. 
'Alert: p. 504.) 

T. tursicus was collected by the ' Alert ' at Darros Island, one 
of the Amirante group. I have copied on pi. 69, fig. 27, Mr. 
Smith's figures. The species apparently is not a Bolma, but with- 
out examining the shells and ascertaining the position of the 
nucleus and nature of the whorls of the operculum, I am not able 
to form an opinion as to its true position. 

Subgenus Cyclocantiia Swainson, 1840. 

Shell conic or depressed trochiform, usually im]>erforate ; whorls 
above smooth, granulate or plicate ; periphery spiuose, tuberculate, 
or with a ])rojccting flange ; base convex, flat, or concave, concen- 
trically lirate ; columella with a more or less obvious tubercle at 
the base ; operculum oval, convex outside, with a more or less 
prominent curved central rib, its terminations connected or nearly 
so by a straight short accessory rib. 

Indo-Pacific, Australo-Zealandie and Juj)0)iic Provinces. 


Synonyms: Stella (Klein) H. and A. Adams, 1858, (type, A. 
asteriscns Rve.), Calcar Montfort, 1810, (type, A. calcar Linn. ?) 
and Carinidea Tenison-Woods, not Swainson. 

There has been considerable diversity of opinion regarding the 
group above defined, both as to its contents and its proper designa- 
tion. Stella was the first name proposed for it ; but since the no- 
menclature (almost) universally adopted by zoologists dates from 
the publication of the tenth edition of Linmeus (1758), we are com- 
pelled to reject the names proposed by Klein in 1753. This course 
is rendered the more imperative by the nature of Klein's work ; for 
his " genei-a " are as often denominated by a phrase as by a single 
word. Calcar of Montfort was probably founded on a species of 
this subgenus. But this is very uncertain, as his figure might be- 
long to any one of several very different forms. (See also Fischer, 
3fan. de Conch., p. 813.) As to Carinidea Swains., which Tenison- 
Woods has supposed to include the group of A. Jimbriatum, A. ten- 
toriiforme etc., there is no warrant for using it in any such sense; 
for Swainson's two types are (1) an umhilicated species of Trochus, 
and (2) a species of Uvanilla, (A. buscJiii Phil.). Hercoles Montf. 
referred to this group by some authors, is not a mollusc. As to the 
limits and contents of Cyclocantlia, as here defined, I am aware that 
there is room for controversy. Fischer and others have distributed 
a portion of the species among several adjacent subgenera. I have 
included with considerable hesitation A. fimbrlatum and A. tentorii- 
forme.; but I do not think that they would be any better placed 
with ^4. olivaeeus etc. in Uvanilla. 

It is very difficult to express in a diagnosis the differences be- 
tween the shells of this group and of Astralium, .s. s. Both contain 
flattened wheel-shaped umbilicate forms, with long peri2:)heral 
spines, and both have com]:)act trochiform species. The two groups 
occupy almost opposite areas upon the globe. 

A. CALCAR Linn., 1758. PI. 52, figs. 27, 29, 30 ; PL 56, fig. 74. 

Shell conoid, more or less depressed at ajiex ; grayish greenish, 
or brownish cinereous ; whorls 6, flattened above, and radiately pli- 
cate, the folds rather unequal and irregular ; periphery carinated 
spinose, bearing about twelve radiating more or less foliated spines 
upon the body-whorl ; last whorl deeply descending toward the 
aperture ; base convex, concentrically more or less densely squa- 
mosely lirate, the outer lirae generally prominent and subspinose, 
sometimes causing the periphery to appear bicarinate ; ajjerture

023erculum oval, nucleus submarginal ; outside deep bluish-green, 
excavated around the upper margin and near the middle, edges 
rugose, center nearly smooth. 

Trochus aculeatus Gmel. is a synonym. 

An extremely variable species. In form it may be either conic 
with nearly flat base, or flat above with very convex and uuibilica- 
ted base. The spines are generally triangular and oliliquely wrink- 
led above, but are often square and elaborately foliated at the ex- 
tremities. Restricting the typical calcar to shells with moderately 
exserted scalariform spire, depressed a{)ex, and body- whorl deflected 
toward the aperture, we may define several varieties which are typ- 
ically quite distinct, but which, in the large series before me, are 
connected with each other and with the type by insensible grada- 

Var. HELiciNUM Gmel. PI. 52, figs. 28, 31. 

Last whorl not descending ; spire conical, not much depressed at 
apex ; marginal spines generally short. Usually larger than the- 
typical form. A specimen before me measures : alt. 40, diam. 70

tuberculated ; base convex, very closely irregularly scaled. (Reeve.) 
Habitat unknown (Reeve); Levuka, Eiji,12fms. (Challenger Exjxl.) 

Watson, who places this species in " Bolina " (= Bolma), says : 
" There are two specimens of this species in the British Museum, 
which differ from one another in the number of spirals on the base 
and. have only a faint tinge of purple at the pillar. In the two 
Challenger specimens, the scaly spirals are much fewer, and a bril- 
liant crimson streak to the left of the pillar, and also in front of it 
on the left corner of the l)asal mouth li}), is a marked feature. I 
observe, however, that as is often the case with these brilliant col- 
ors, the crimson has somewhat faded during the years the shell has 
been in my hands." 

A.siRius Gould, 1849'. PI. 45, figs. 93-95. 

Shell small, low pyramidal, pale emerald green ; whorls 4, acute-

about eighteen on the peri2:)hery of last whorl ; surface corrugated 
by oblique wrinkles ; base nearly flat, imperforate, with about five 


-delicate, distantly nodose, concentrip, iuequal lirse ; aperture circu-

T. rJiodostomus Lam., and T. tuberosus Reeve (not Phil.) are syn- 
onyms. T. spinidosus Reeve is probably a depressed form of this 

Martyn's name has been overlooked by most authors, but I see 
no reason for rejecting it for that of Lamarck. His figures in the 
" Universal Conchology " are so superior as to compare favorably 
with modern work ; and represent unmistakably the typical form, 
Avith the two subequal rows of spines upon the j)eriphery.

This is Troch'us stellatus of Philippi and of Reeve. It may possi- 
bly be the stellatus of Gmelin. That species was said by him to be 
West Indian. 

In some specimens the peripheral sjjines are rather long and direct- 
ed outward. The liras of the base are sometimes coarser than the 
figures indicate ; and in fully matured individuals the outer ones be- 


come obsolete ; finally, the base of the aperture acquires the arma- 
ture shown in fig. 18.

The following species have been placed in Uvanilla by Fischer; 
but they do not seem to be as nearly allied to U olivacea, the type

ribbed ; operculum oblong, narrow, the nucleus terminal ; outside 
very convex, white, smooth, with a broad central convexity and ob- 
solete narrow side ribs. 

Californian Province. 

I restrict this subgenus to A. inequale, the first species mentioned 
by Gray in his description. A. ccelatum Gmel., usually classed here, 
belongs to a wholly different section of the genus. 

A. inequale Martyn, 1784. PI. 57, figs. 51, 52. 

Shell conic, imperforate, rather solid, with a chestnut brown cuti- 
cle, lighter beneath ; whorls 6-7, planulate above, sutures slightly 
impressed, bordered below by a series of obliquely descending cor- 
rugations, which are cut into granules by from one to five spiral 
furrows ; periphery carinate, subspinose on the upper whorls, usual- 
ly nearly smooth on body-whorl ; base nearly flat, concentrically 
lirate, the lira^ more or less tuberculate, five or six in numbei', their 
interstices regularly striate ; aperture subtriangular, white within. 


the lower margin fluted; columella arcuate, broad, excavated at 
position of tlie umbilicus, and terminating in a tooth-like promi- 
nence below. Alt. 45, diam. 55-62 mill. 

Western America, Acapulco to Vancouver Id. 

Operculum (pi. 60, figs. 68, 68a) inside deep brown, convex at up- 
per, concave toward lower margin ; outside smooth, or rugose at the 
distal extremity, and white, brownish toward the nucleus.

The name inequalis Martyn, here adopted for this species, has four 
years priority over Chemnitz's name. Besides, the latter author 
was a polynomialist, and merely copies Martyn's excellent figures 
of the species. 

Genus LEPTOTHYEA (Carpenter^ Dall, 1871. 

Shell small or minute, globose-depressed, solid, compact; umbili- 
-cate or imperforate, whorls .S-7, spirally sculptured, the last generally 
somewhat deflexed at the aperture; aperture subcircular, white and' 
nacreous within; columella generally but not always bluntly den- 
ticulate near the base. Operculum subcircular, nearly flat or 
concavo-convex, inside with a very thin corneous layer, slightly 
convex, w'ith many gradually increasing wd^orls, the nucleus sub- 
-central; outside calcareous, subspiral, with a slightly convex con- 
centric elevation or ridge around the margin, most prominent at 
its termination, the middle portion concave and more or less rugose. 

The species are numerous, inhabiting nearl)^ all tropical and sub- 
tropical seas; but most numerous in the Pacific. 

The synonymy includes Collonia Gray (in part), Collonia of most 
authors, Leptonyx and Homalopoma. Carpenter (pi'eoc), Cantrainea 
Jeftreys, Ca.ntraiiieia Fischer, Anadema H. & A. Adams. The 
genus is very homogeneous, and neither of the subgenera proposed, 
(^Cantrainea Jeff", for L. carinata, and Anadema Ads. for L. coelata 
Ad. have sufficient characters for any systematic rank. 

The characters of the dentition are discussed on p. 188. The 
rank and position of this group has been the subject of considerable 
controversy; but partly, perhaps, on account of the minute size of 
the species, partly because of the scattered and inexact condition of 


the literature relating to it, the grouj) has never been made an 
object of critical systematic study. Previous monographers have 
included the few species noticed at all in Turbo and Trochiis. 

As to the family affinities of Leptothyra, the totality of its charac^ 
ters seem to me to indicate that its position is at the end of the 
Turbiiiidce, rather than in the Trochidce, where it has been placed 
by Von Martens, Tryon and others. There is, in fact, no character 
save the ulultispiral operculum, which at all affiliates Leptothj/ra to 
the latter family; and, as I have shown, (p. 184), all the genera of 
Turbmidce possess in the very young stage, multispiral opercula 
precisely similar to that of Leptothyra ; so similar, indeed, that they 
are scarcely distinguishable from it. It is altogether probable that 
the Turbines are a divergent branch from the Trochid stem ; and 
that Leptothyra and Collonia .represent the primitive condition of 
the entire family. 

The more complex structure of the operculum in the Turhinidce 
and the reduction of the lateral teeth to five on either side, — a 
number frequently exceeded in the Trochidw, — indicate higher rank 
than the latter family. 

X am inclined to believe that the relationship of Leptothyra to 
Collonia is very close, I am not, however, autoptically acquainted 
with the latter genus ; and until we are in possession of fuller infor- 
mation regarding it, I deem it best to retain them separate, 

I will briefly recapitulate the history of the 

Genus Cqllonia Gray, 1850. 

" Operculum circular, of many gradually increasing whorls, with 
a convex external rib and central pit. Shell top-shaped, solid, 
spirally striated, imperforated ; aperture circular, contracted ; inner 
lip rather callous. Tyjie, C (^Delphinula) marguutta Lam." 

This genus was described from a Paris Basin Eocene fossil, but 
was evidently intended by its author to include also the recent spe- 
cies of the type of Turbo sanguineus L. In this "wider sense the 
name Avas used by most authors until 1864, when P. P. Carj^enter 
proposed for the recent shells the name Lejytonyx, which being pre- 
occupied was changed to Leptothyra. Dall, Fischer, and a few 
others, accepting this division, have restricted Collonia to the fossil 
forms. My information regarding the genus as thus restricted is 
derived from the original description copied above, and from the 
figures of operculum and shell of the type species given by Deshayes 


and by Woodward. (PI. 00, figs. 61, 62.) I do not understand 
the discrepancy between the description of the operculum and De- 
shayes' figure of it. The main character distinguishing Gollonia 
from Leptothyra seems to be the peculiar peristome of the former. 
Fischer says of it: "peristome continu, epaissi, dilate, excepte sur le 
bord columellaire ; labre epais, parfois su])double on subreflechi. '■' 

^ ^ >!< 

Les coquilles de ce groupe ne paraissent pas avoir ete nacrees- 
Leur opercule ressemble a celui des Leptothyra, mais leur ouvertiire 
rappelle celle des Liotia." (Manuel de Conch., p. 812.) 

There are numerous Tertiary species. 

Note. The operculum of Leptothyra frequently otlers excellent 
specific characters, just as it does in Turbo and AstraUum ; and at- 
tention to these will often enable one to readily separate sj^ecies of 
which the shells exhibit considerable similarity. 

L. CARPENTER! Pilsbry, 1888. PI. 39a, figs. 26-29. 

Shell small, globose, very solid, imperforate, spire conic, more or 
less depressed ; suture moderately impressed ; whorls 5, slightly 
convex, the last decidedly deflected toward the aperture, encircled 
by about fifteen subequal spiral lira?, separated by interstices about 
as wide as the ridges ; incremental strire generally strongly devel: 
oped, causing the lirse to appear nodose or somewhat irregular, and 
the interstices to appear pitted ; aperture oblique, pearly white 
within, about half the length of shell ; columella arcuate, base ob" 
soletely uni- bi- or tri-dentate ; color red, ashen or purple. 

Alt. 8, diam. 8-9 milh ; dark form alt. 5, diam. 5 mill. 

Cape St. Lucas, L. California to Vancouver Id. 

Operculum (pi. 60, fig. ^'o) rounded oval; outside much thinner 
and less elevated around the margins than that of X. sanguinea, 
slightly concave in the middle, nearly smooth. 

This is L. cocci neus of Troschel, not Miihlf., Ij. calijornicus von 
Martens, not of Philippi, L. sanguineus of Carpenter and authors 
generally, not of Linn., and vav. purjmreus Carpenter, (preoc). 

The Californian shells a})pear to me to be quite distinct from the 
Mediterranean species ; I have been unable to find, in the numerous 
specimens of the latter form which I have examined, any trace of 
the peculiar indentations in the grooves or of the uneven character of 
the lirae which are so conspicuous in the Californian species. The 
lirse ofX. Carpenteri ai-e genei-ally smaller and more numerous; 
about five or six are visible on the penultimate whorl ; and those 


upon the base are but little, if at all, uarrower than the upper ones ; 
whilst iu L. sanguineus and X. sangarensis the difference in width is 
decided and constant. I have seen specimens of L. carpenteri 
strongly lirate both above and below. As to color, "the species is 
of all shades of crimson and purple, some specimens being banded 
with white, or having the red color of the ribs interrupted by ob- 
lique streaks of white ; some specimens, excepting the dark apex, 
being pure white." (Dall.) 

I did not adopt the varietal name pHrjnireus, proposed by Car- 
penter, because it has already been twice used in this genus. 

L. PAucicosTATA Dall, 1871. PI. 63, fig. 27. 

Shell small, depressed-globose, solid, imjjerforate ; whorls 4, rap- 
idly increasing, very strongly spirally lirate, the lirse seven to eight 
in number on the last whorl, separated by deep grooves, iu which 
incremental strife are evident ; sutui*es canaliculate ; aperture con- 
tracted, pearly white within ; columella ending in a callous tubercle; 
color rusty brown or rose-red, frequently with alternating white 
spots on the ribs, interstices generally lighter, sometimes })ui'e white. 

Alt. 4, diam. 4 mill. 

Monterey, Catalina Id. and San Diego, Cal. 

Most nearly allied to the preceding, but differing sufficiently in 
the extremely coarse prominent ribs. 

L. BACULA Carpenter, 1865. PI. 39«, fig. 33. 

Shell small, depressed-globose, solid, imperforate, rufous ashy ; 
whorls 4, slightly convex, rapidly increasing, obsoletely but regu- 
larly spirally striate ; aperture large, oblique, deflexed above. 

Alt. 4, diam. 5 mill. 

CoUoiiia paucicostata Sowb. (not Dall) is a synonym. 

Allied to L. carpenteri, but readily separated by the nearly obso- 
lete spiral sculpture. 
L. MAEGiNATA ("Nuttall") Rceve, 1848. PI. 58, figs. 51, 52. 

" Shell ovate, rather solid, imperforated, spirally striated, slightly 

grooved ; aperture small ; whitish stained and blotched with livid 

olive." {Reeve.) 

Upper California. 

I have copied Reeve's description aud the figures of Reeve and of 

Sowerby — the latter said to be twice the natural size. If this shell 

ever came from California, which is very improbable, it might be a 

form of L. hacula Cpr. It is not the T. maginatus Nuttall mss., 

which is a species of Trochidce. 


L. cuNNiNGHAMi E. A. Smith, ]881. PI. 57, figs. 0(1, 57. 

Shell small, subglobose, perforate in the young state, when adult 
imperforate, of a rose-madder color ; whorls 42 , the apical one whit- 
ish, the rest convex, and finely spirally striated, also marked with 
faint oblique lines of growth ; suture rather deep; last whorl ob- 
li(piely descending near the lip, somewhat flattened beneath near 
the center ; aperture obliquely subcircular, iridescent Avithin ; colu- 
mella pearly, spread over the umbilicus ; labrum with a narrow 
pinkish margin within. Alt. 42 , diam. 5 mill. (Smith.) 

Port Rosario and Portland Bay, Patagonia. 

Operculum as usual in the genus. 

L. SANGuiNEA Linn., 1758. PI. 49, figs. 48, 49 ; pi. 64, figs. 60, 61. 

Shell small, very solid, orbicular, depressed, with conic spire; 
whorls 42-5, convex, strongl}^ spirally lirate, the linie smooth, about 
twelve in number on body-whorl, three on penultimate whorl, not j)er- 
ceptibly crenulated by the very subtle incremental stride ; above the 
lirse are coarse, smooth, and generally irregularly spaced, interstices 
smooth, as wide or wider than the ribs; below more finely lirate ; last 
whorl well rounded, deflected anteriorly ; aperture somewhat con- 
tracted, oblique, pearly white within, peristome rather thick, its ends 
not converging, columella short, slightly arcuate, thick and heavy, 
terminating below in an obtuse tubercle, base of aperture some- 
times bearing an inconspicuous dentiform callus at margin ; color 
deep crimson. Alt. 6, diam. 7 mill. 

Mediterranean and Adriatic Seas. 

The species has also been dredged ofl" the Atlantic Coast of France. 

Operculum (pi. 60, figs. 54, 55) inside slightly convex, light yel- 
low, with about ten very slowly and regularly increasing whorls, 
the last third of the outermost considerably widened ; outside 
calcareous, white, flat, concave in the central area and coarsely ru- 
gose, outer margins with a slightly elevated very finely radiately 
wrinkled concentric rib, which is slightly more elevated near its ter- 

The synonyms are T. purpureus Risso, T. coccineus Miihlf, and 
T. helUa-i Payr. 

The diflerential characters of L. earpenteri, L. sanguinea and L. 
sangarensis are pointed out under the descriptions of the first and last 
species. There is not the slightest occasion for any longer confound- 
ing these three unfortunate species. The occurence of the real Z/. 
sanguinea Linn, in Japanese waters still requires confirmation. 


L. sANGARENSis Sclireiick, 1861. PI. 47, figs. 27, 28 ; pi. 64, fig. 59. 

Shell small, turbinate-conic, almost trochiform, imperforate, solid, 
dark purplish-brown or reddish; sculpture consisting of fine crowd- 
ed spiral concentric lirfe on the base, which is very slightly convex, 
and coarse cord-like lirre above, about five or six in number on the 
body-whorl and with more or less minute lirulse between them : incre- 
mental striuhe visible nnder a lens ; spire elevated conic, subacute, the 
apical whorl white; suture deeply impressed ; whorls 4-5; last whorl 
but slightly descending, subcariuate below the middle ; aperture 
small, less than half the total length of shell, oblique, rounded, within 
pearly, and iridescent; outer lip rather thin ; columella obliquely 
arcuate, rather broad and flattened, very obtusely subtuberculate 
just below the middle. Alt. 7, diam. 6 mill. 


T. coralliuus Keeve (pi. 63, fig. 20) is probably synonymous. 

Quite variable in its proportions, according to Schrenck, one of his 
specimens measuring, alt. 7j, diam. 8 mill. 

This seems to be the shell which many authors have reported from 
Japan as T. sanguineus L. From that species it differs in the conic 
form, more finely lirate base, narrower ribs above, flatter base, etc. 
From L. amussitata the lack of distinct decussation will separate 
sangarensis. I was unfortunate enough to lose the only operculum 
of this form in my possession, before describing it. 

L. AMUSSITATA Gould. PL r)':,, figs. 71^ 72. 

Shell globose-conic, imperforate, solid, uniform deep crimson ; sut- 
ures deeply impressed ; whorls 5, convex, spirally lirate, the lirsfr 
large and prominent on middle portion of Avhorl, alternating with 
smaller intercalated riblets ; base very finely concentrically striate,, 
the whole surface decussated by numerous regular oblique impress- 
ed lines in the direction of incremental striae ; last whorl descending 
anteriorly; aperture subeircular, oblique, less than half the length 
of shell, silvery within ; columella slightly tuberculate at base. 

Alt. 8-10, diam. 8-10 mill.

CoUonia rubra A. Ad., mss. is a synonym according to Sowerby. 
A charming little shell, easily separated from its allies by the 
finely decussated surface.

Shell small, solid, globose ; Avhorls 4-4^, rotund, marked with sub- 
grauose transverse costulse ; suture obvious; aperture rotund, irides- 
cent and pearly within ; lip thickened.

Collonia rubra Dunker, Ind. Moll. Mar. Jap., p. 128, pi. 12, f. 7-9. 

Nearly allied to L. sangidnea L., but differing in the sculpture of 
the ribs. 

L. PURPURASCENS Dunker, 1882. PL 69, fig. 24. 

Shell globose, whorls 5, rounded, separated by subcanaliculate 
sutures, transversely sculptured by unequal graniferous costulse ; 
aperture rotund, sulcate within and pearly ; columella thickened. 

Alt. 8, diam. 9-10 mill. (Dunker.) 


Collonia purpu7-ascens Dkr., Ind. Moll. Mar. Jap., p. 129, pi. 12, 
f. 1-3. 

I have not seen this species, nor L. rubra Dkr. Both are allied 
to amiissitata Gould, and purpurascens may prove to be a synonym 
of that species. X. rubra seems to be distinct. 

L. PURPURATA Desh., 1863. PL 54, fig. 61. 

Shell minute, turbinate, subglobose, imperforate, somewhat de- 
pressed, vivid purple, white-fasciate in the middle; whorls 4, the

elevated contiguous cinguli; the upper one nodulous, brick-red, the 
basal white, encircled by a deep red band ; aperture circular, white, 
columellar margin thickened. {Martens.) 


L. ROSEociNCTA von Martens, 1880. PL 68, figs. 14-19. 

Shell globose, imperforate, smooth, white, apex rosy, peripheral 
fascia rather wide, frequently composite, rose-colored, basal fascia 
narrow; whorls 31, slightly convex, the last rotund ; suture super- 


ficial ; base slightly excavated at the position of tlie umbilicus ; aper- 
ture oblique, circular ; peristome white, thickened.

parently a species of Astralium.) 

Troehus glahratus Phil., Fauna Moll. SiciL, 1844, is synonymous. 

This deep water form of the Mediterranean and adjacent Atlan- 
tic, seems to be specifically identical with the Western Atlantic 
shells dredged by the Challenger and the Blake and describ- 
ed under the names T. indutiis Watson and L. albida Dall. I 
have before me specimens of the latter form which correspond very 
nearly .with Cantraine's figures.

Small, couoidal, high, whorls tumid, base flattened ; color white- 
glossy ; whole surface faintly marked with remote spiral threads,, 
and very faintly scratched with closer microscopic striae ; whorl& 
bluntly angulated in the middle, and the last is so, besides, at the 
base below the j)eriphery ; this angulation meets the outer lip ; the 
the second and third whorls have two or three strong spiral threads , 
there are very many close unequal oblique lines of growth ; of these 
the strongest rise in close-set infra-sutural puckerings, which on the 
third whorl resemble small beads ; there is a glossy, thin ivory- 
white calcareous coat over a brilliant pearly white layer ; spire high, 
fine-pointed; apex blunt, the smooth rounded 11 whorl scarcely 
projecting ; whorls 6, of rapid increase, tumid, the penultimate ris- 
ing swollen out of the suture ; base a little flattened ; suture linear, 
not impressed, a little coarse, slightly marginated by the up-lap ot 
the succeeding on the preceding whorl and the slight tumidity 
caused by the infra-sutural puckerings ; aperture very oblique^ 
round, with a soft pearly nacre all round : outer lip very slightly 
descending, thick, bevelled outwards to a sharp edge; there is a 
broad thin hyaline pad spread over the body and connecting the 
outer lip and the pillar, which is broad, thick, shallowly excavated, 
with a slight external median horizontal tooth or ridge ; the edge is 
reverted and closely appressed. Alt. '27, diam. -25 inch.

suddenly to enlarge. ( Watso7i.) 

Although I have above expressed the opinion that this species a& 
well as the following one, is identical with L. carinata Cantraine, I 
have deemed it best to give the original description and figure.

ing from three to six on the upper side of the whorl, crossed by 
slight plications, most noticeable just below the sutures, but distin- 
guishable also on the base; the ribs may be few and widely separat- 
ed, or numerous and close-set; they may near the sutures be nodu- 


lated by the plications or not. The base is usually more finely 
sculptured and sometimes quite smooth except for lines of growth." 


Aperture very oblique, small, its upper margin produced forward

A variety has the dark color replaced by scarlet ; the spiral 
costse are articulated with white and scarlet. 

The above two descriptions are derived from the original ones of 

L. MACULOSA Pease, 1862. PL 57, fig. 60. 

"Shell small, globose, umbilicate, rather thin, shining, concentric- 
ally irregularly ribbed, interstices grooved, concave, transversely 
very faintly striate, white, ribs spotted remotely with rose red" (Pwse). 

Alt. 2, diam. 1 1 mill. 

Ins. Panmotus. 

To Pease's description of this lovely species, I would add that the 
spire of adults is more obtuse than his figure, which I have copied^ 
indicates. The altitude is about equal to the diameter; the subsut- 
ural rib is frequently nodose ; and the umbilicus, as in the follow- 
ing species, is cu-enated within the margin. It is most nearly allied 
to L. pieta Pse. 

L. CANDIDA Pease, 1860. PI. 63, fig. 40. 

"Shell minute, thin, perforate, orbicular, ornamented with raised 
spiral striae (margins of upper whorls granose at the sutures?) inner 
lip callous ; aperture circular." (Pease). 

Sandwich Is. 

I have given Sowerby's miserable figure of this species. I have 
not seen specimens ; and so inadequate a description does not deserve 

L. PicTA Pease, 1868. PI. 69, fig. 35. 

Shell small, solid, globose, umbilicate, concentrically ribbed ; spire 

somewhat exsei-ted ; whorls angulated at their upper part ; aperture 

circular; columella slightly callous; wdiitish, striped on the upper 

part of the whorls longitudinally with reddish brown, below spotted.

Operculum, pi. 60, ng. 63. 

The upper whorls of the spire are grannlose above. There is con- 
siderable variation in the prominence of the \irse on the central por- 
tion of the body-whorl ; the margin of the umbilicus is more or less 
plicate ; and the last whorl is slightly deflected toward the aperture. 


I.. RUBRiciNCTA Migliels, 1845. PI. 39a, fig. 32. 

Shell minute, depressed-globose, perforate ; spire short, apex ob- 
tuse ; Avhorls 4, convex, encircled by coarse white spiral ribs, the in- 
terstices deep red ; base smooth, with concentric red stripes ; aper- 
ture large, rounded, oblique ; umbilicus narrow. 

Alt. Il', diam. If mill. Hawaiian Is. 

The synonyms are Turbo inHltllineata Garrett, Collonia rubrilin- 
eata and C. miiltistriata (Pse.) Sowerby, and Leptothyra ruhrilineata 
(Garrett) v. Martens. 

Some specimens are beaded below the sutures, and there is some 
variation in the width of the umbilical perforation. The revolving 
ribs are sometimes obsolete ; but so far as I know the red spiral 
stripes are constant ; of these there are usually eight to double that 
number on the body-whorl. 

Mr. Pease distributed this species under the name of "ruhrilineata 
Garrett." This fact probably accounts for the names quoted by 

L. EXiLis Philippi, (1849?) PL 62, figs. 3-5. 

"Intermediate between T. sanguineus and T. ruhricindus, and 
separated from both by its rather wide umbilicus ; there are 4 whorls, 
which are rapidly increasing and well rounded ; the spiral ridges are 
about 12 on the body-whorl, but vary in number ; they are subgran- 
ulose, and at the suture distinctly tuberculose. The border of the 
umbilicus is crenated ; aperture circular ; color bright carmine, some- 
what lighter in the furrows ; umbilical tract pure white ; aperture 
inside pale red." Alt. 3i mill.

bilicate, white with numerous revolving series of red or broAvn tessel- 
lations ; whorls 5, spirally lirate, the lira largest at middle of whorl, 
and sometimes causing a slight carina there ; last whorl slightly but 
abruptly deflected anteriorly; aperture circular, white, columella 
arcuate, wide, white, not dentate below ; base with a minute inter- 
nal denticle. Alt. 5, diam. 5 mill. 

Sandwich Is. 


Some specimens are almost entirely red ; others are white, with red 
spots at the periphery. There is some variation in form, also, and 
in the prominence of the spiral riblets. 

Turbo g/ariosa Gould is a synonym, according to Sowerby. I can- 
not find that Gould ever described such a species. 

An annoying tangle in the synonymy of this speeiesand L. rub ri- 
cincta Migh. resulted from the identiHcation of Gould's verruca with 
Mighel's species by Mr. Pease, and, following him by Von Martens,, 
who figures and describes rubricinda Migh., under the name rubri- 
liueata Garrett, aiid verruca Gld. under the name rubrioincta Mighels..

A well marked form, of wide distribution, of which I have before 
me many examples, all agreeing in the peculiar operculum. I can- 
not follow Sowerby's synonymy in this group ; beseems to have unit- 
ed species from a mere superficial likeness. Here, as in the typi- 
cal Turbo and Astralium, the characters derived from the opercula 
are of high specific value, and this organ should be examined before 
uniting the numerous described species.

'' California " (Philippi:) 

This species is apparently very nearly related to the T. sanguin- 
eus L., but is distinguished by the crowded transverse strise of the 
upper surface, by the narrowly but conspicuously umbilicate base, 
■by the plica^ within the outer lip, and finally by the coloration, 
which consists of large deep-red maculations above at the suture 
and in the middle of the lower side, and smaller paler flecks around 
the umbilicus and at the periphery. I see no tubercle ujion the 
columella. (Philippi.) 


Von Martens (Xachriclitsbl. d. JNIal. GeselL, 1878, p. 88,) consid- 
ers this species the same as Leptothyra sanguinea Carp, {non Linn.) 
-= L. carpenteri Pilsbry. The al)ove description, translated from 
the original one of Philippi, shows it to belong to an entirely differ- 
ent group of species — tliat of L. Iceta Montrouzier ; and it may in- 
deed be nothing more than a bright colored example of that species. 
At all events, nothing of the sort has been found upon the Califor- 
nian coast.

Synopsis of recent Genera. 

Genus DELPHINULA Lamarck, 1808. 

Shell rather large, solid, umbilicated, turbinate, the upper whorls 
flattened, the last descending, rudely spinose or scaly, more or less 
carinated, but slightly in contact with the preceding ; aperture cir- 
cular ; peristome usually sgmewhat produced at base. 

Angaria (Bolt. 1798) H. & A. Adams, 1858, is a synomyn. 

In this genus were formerly included the species now classed in 
Liotia, Collonia and some other genera. 

Subgenus Angarina Bayle, 1878. 
Shell depressed, discoidal, sinistral (?), widely umbiiicate, spirally 
lirate, aperture , rounded ; umbilical area bounded by a series of 
spines. Animal and operculum unknown. Delphinidopsis Wright, 
1878, (preoc.) is synomymous. Probably not a valid genus. 

Genus DELPHINULA, Lam., 1803. 

D. LAciNiATA Lamarck, 1819. PI. 67, figs. 1, 2, 4. 

Shell depressed-turbinate or nearly planorboid, solid, heavy, um- 
biiicate; whorls 42, the inner ones planulate, planorboid, apex 


minute; body-wliorl descending, frequently free or nearly free from 
the preceding, iu section subtriangular, angled below and less con- 
s])icuously so at the shoulder ; all over finely spirally Urate, the lira; 
either smooth, densely squamose or spinose ; perii^hery bearing 
large irregular more or less hollow foliated processes, which droop 
foreward or downward ; one or two series of smaller spines usually 
revolve about the middle of the last whorl ; base carinated, the 
carina usually nodose or irregular, bounding a circumumbilical 
tract usually acutely squamose ; the umbilicus proper is narrow 
and deep ; aperture rounded trigonal, inside perfectly circular, 
pearly, white or tinged with golden ; peristome irregular, acute, the 
columellar margin sinuous, the base more or less produced. Color 
whitish, pink or yellowish, the projecting processes and spinelets 
often redder or blackish.

Turbo delphin.ul\is of Linn?eus, was undoubtedly the first binomial 
name applied to this form ; but since, it has been ignored by authors 
for more than a century, science would probably not be benefitted 
by an attempt to revive it. 

The variation in foi'm, sculpture and color iu Delphinula is very 
great. I am unable to distinguish the numerous species described 
by Reeve. The last whorl, in D. laciniata, may be deeply descend- 
ing, almost or quite free from the preceding at the aperture, or it 
may be but slightly descending, nearly planorboid. Its upper sur- 
face is plane or very obscurely radiately undulate. The peripheral 
spines in the typical form defined above, are large, foliated, and 
drooping ; but are nearly as frequently narrow and subsimple. The 
following varieties may, when typically developed, be distinguished ; 
but the transition forms are more numerous in collections than the 
typical ones. 

Var. ATEATA Reeve, 1842. PI. 66, fig. 15. 

Differs from the type in having the superior series of foliations or 
spines less conspicuous and those upon the middle and base of the

Whorls rounder, less carinated below than in the type; surmount- 
ed by a corona of slender long radiating or ascending spines ; um- 
bilicus wider. 

D. imperiaUs Reeve and I), distoiia Kiener (not Lam. nor Linn.) 
are synonymous. 

D. SPH-V.RULA Kiener. PI. 67, fig. 5 ; pi. 68, fig. 20. 

I know this form only by the description and figures given by 
Kiener. The latter are copied on my plates. In the simple, appar- 
ently very regular spines, the form is different from any specimens 

I have seen. 

Indian Ocean. 

D. DiSTORTA Linn, 1758. PI. 65, fig. 8 ; PI, 68, figs. 12, 13. 

In general form similar to D. laciniata. Upper surface of lohovh 
radiately conspicuously plicate, the folds terminating in solid knobs 
or short spines at the carina ; lirse rather coarser than in laciniata ,- 
base of body-whorl rounded or only obtusely carinated ; the sculpt- 
ure and color of the umbilical area not notably different from that 
of the whorl outside ; color white or pink, the line, spines and scales 
deep crimson; size smaller than laciniata. Alt. 30, diam. 40 mill, 
or less. 

, Indian ; Nicohar Is., etc. 

This is the Tarho distortm of Linn., Delphinula distorta Lam., 
and D. rugosa of Kiener's plates. 

Afc far as my material allows me to judge, this form does not in- 
tergrade with D. laciniata. 
D. TYRiA Reeve, 1842. PI. 66, figs. 12, 13. 

In general form like D. laciniata. Whorls angulate at the shoul- 
der, rounded or obtusely angular around the umbilicus, covered all 
over with densely and acutely squamose lirse ; upper surface of 
whorls plane or gently radiately undulating; color white, the um- 
bilical region and a subsutural spiral band, deep purple or purplish 

crimson. Alt. 45, diam. 50 mill.

D. NiTiDA Verrill and Smith, 1885. PI. fi5, fig. 10. 

Shell t^mall. fragile, very delicate, with a slight .«ilvery iridescence. 
Our specimen which has lost the apex, consists of o gradually en- 
larging whorls, entirely disconnected with each other and nearly 
round in a cross section. When perfect the spire must have been 
rather elevated, gradually tapering to an acute tip. The surface is 
sculptured by thin elevated riblets, crossed by distinctly raised re- 
volving lines of about the same size, producing a pretty regularly 
cancellated or reticulated sculpture, in which the meshes are mostly 
elongated in the direction of tlie spire around the periphery, but in 
the opposite direction on the lateral and inner surfaces ; the trans- 
verse riblets are m^ist elevated on the uj^per sides of the whorls, 
where they rise into small thin lamellre ; they also form similar 
lamellae on the inner and lower surfaces ; the revolving lines are 
most consijicuous ai'ound the periphery ; minute but distinctly 
raised lines of growth also cross the intervals between the riblets. 
In a front view of the base the shell ajipears umbilicated, and the 
upper whorls can be partially seen within the umbilicus. Color 
silvery white, slightly iridescent. Alt. (of last three whorls) 5, 
diam. 4 mill. ; diam. of aperture, 1'6 mill. (Verrill.) 

Off' Chesapeake Bay, in. 1428 /»i6-. 

Animal unknown. The systematic position of this form is un- 
certain ; but tlie pearly structure of the shell indicates, as Verrill 
observes, that it belongs in the vicinity of Delphinula. although not 
I believe, strictly speaking, to tliat genus. 

Subgenus Angahina Bayle, 1878. 

A. LESOURDi B. Wright, 1878. PI. 6S, figs. 6-8. 

Sinistral, profoundly perviously umbilicate, depressed, suborbicu- 
lar, somewhat solid, transversely cbstate lirate, pale greenish, macu- 
lated with chestnut ; spire plane, suture profoundly impressed, 
broadly canaliculate ; whorls remaining 4-2, (the apex wanting,) 
spirally lirate, the costte about 14 in number; base bearing a series 
of short spines; umbilical area white within ; aperture round, pearly 
within, peristome simple, the columellar margin subexpanded. 

Diam. 41, alt. 24 mill. 


Described from a single young specimen, which has every appear- 
ance of being abnormal. Fischer surmises that the shell is really 


dextral, instead of sinistral, as described by Wright, the spire im- 
mersed, forming a false umbilicus. Von Martens suggests that it is 
a distorted Turbo. ('ompare the sculpture with that of Turbo cor-

N. NORDQuisTi AVesterlund, 1887. PI. 68, figs. 9-11. 

Ovate, semiglobose, closely striate, with incremental wrinkles, 
densely covered with spiral lines; black or rarely brownish-olive, 
concolored or painted with numerous black points in transverse series, 
black rhomboidal reticulations, or variously marked with pale yelloAV ; 
spire prominent but nearly always eroded ; body-whorl strongly de- 
pressed, subconcave at the suture ; suture appressed, anteriorly 
subdescending ; ajjerture bluish within, angular above ; outer lip 
slightly curved, basal margin arcuate, columella slightly sinuous, 
obtusely denticulate , columellar area grayish yellow, finely rugose 
and foveolate, its superior portion brown, sliining, punctate.

PHASiAXEr.LA, subgeuus Orthomesus, Pilsbry. 

P. splendida Philippi, 1849. PI. 39a, fig. 5. 

This form 1 inadvertently jilaced in the synomymy of P. variegatct 
Lam. (p. 179). It seems to be quite distinct from that species. I 
translate Philippi's description, Avliich applies perfectly to the speci- 
mens before me. 

" Shell ovate-oblong, conoid, very thin, very smooth and shining, 
olivaceous, sometimes varied by narrow milk-white fianuiiules marked 
Avith transverse red lines articulated with white dots ; aperture ovate, 
longer than the spire. 

" The shell is long-oval, conoidal, thin, very smooth and very 
shining. The whorls seven in number, are moderately convex The 
last occupies more than half the entire altitude. The two embryonic 
whorls are milk-white, and form a blunt apex. The aperature is 
rather broadly ovate. The color is olive-brown, verging on red, 
sometimes with narrow milk-white fiammules, always with evenly 
spaced red spiral lines, which are regularly interrupted by milk- 


white points, and which are visible within the aperture. {Philippic 
in Kilst. Conch. Cab., ii, p. 8.) Alt. 10, diani. 7 mill. 

Red Sea.. 

P. hrongniartl Audonin is a synomym of this form, not of P. varie- 

I neglected to state in the text that fine spiral capillary lines upon 
the shell are characteristic of the species of Orthomesiis, but are not 
found upon the true PhaslaneUa nor on TrlcoUa. Variable as is the 
coloration of shells of this family generally, these fine lines seem ta 
be most constant. 

P. MARMORATA Dufo. p. 183. 

I have identified with this form a series of shells from the Sey- 
chelles which I have received, but, unfortunately, too late to figure 
it in this volume of the Manual. The locality should read, Sey- 
chelles and Amirante Is. 

T. magnificus Jonas, p. 192. 

The figure given on pi. 40, does not show the characters of this 
species as well as is desirable. The original figure given by Philippi 
is copied on pi. 69, fig. 21. 

T. militaris Reeve, 1848. PL 69, fig. 31. 

Tlie figure of this species in the Iconica led me to believe it aform 
of T. pefhnlatus. If Sowerby's figure, copied on my pi. 69, fig. 28, 
really belongs to militaris, I am inclined to think it distinct. Fig. 
29 is a copy of the original one of Reeve. 

P. 191, seventh line from bottom, read Senectus (Humph.) IT. 
and A. Ad((vis, not Senectus (Humph.) Swainson. The latter author 
applied this name to the typical Turbo. \
