Genus HPiLICINA Lamarrk.

Testa tenrstre, kelici/oiinis, conica, lenticularis, met

globosa ; apertur<r tnargine intemo rectiuscido,

manjine externa pkrumqite rejhxo vcl iiicrassato.

Operculum concent i-i cum, testaceum vel coi-neum, oblique

semilunari vel subquadralum, nucleo subceatrali.
Slicll terrestrial, helieiforiii, conicul, lenticular or
globose ; inner edge of aperture ratlier straight.
outer margin generally reflected or thickened.
Operculum concentric, shelly or horny, obli(iuely semi-
lunar or subquadrate, with nearly central nucleus.
It is difficult to accept as useful the numerous
generic divisions into which the species of this genus
have been .separated. The pas.siiges from the conical to
the globose, the globose to the lenticular, the notched to
the entire columella, the impercei)tible to the thick
rounded callus, the rounded to the angular, and thence
to the keeled body-wliorl, are made bv almost impercep-
tible gradations. That being the case, it is impossible to
define snch genera as Trochatella, Alcudin, Lucidella,
<tc., so as to distinguish them from each other, and
from llelirina ; while, on the other hand, they unitedly
form a genus of varying forms, but fairly included in
one genus as defined above.

The llelicina abound more on islands than on con-
tinents, jireterring the tropics. Cuba, the West Indian
Islands, especially Jamaica, the Philijjpines, and the
Pacific Islands are among tlieir favourite habitats,
although the tropical, and even the nortliern parts of
the .American continent ]iroduce many species. The
rapid increase in the nuniber of known species that has
t.aken place in this genus is very remarkable. In 1842
Mr. Sowerby publi.shed 7;i species, a large proportion
of which were then recent discoveries; and in 18GG his
2nd Monograph with 270 species. In the present
work we describe 310.

Testa bivalvi, bhmisculosa, utrinque hians, laevigata, vel

medio ulraque valvd uiiidentato ; ligamcnto con-
spicuo, e.rterno ; impressioiie pallii posiice profunde

Shell bivalve, bimiisciilar, gaping at both ends, smooth
or concentrically wrinkled, covered with an
epidermis, hinge with one tooth in the middle in
each valve ; ligament conspicuous, external ; palloal
impression with a deep sinus.

Some of the species included in this monograph are
separated under the name Glycimeris in the work of
Messrs. Adams. The shells of both genera are stated
to be similar, excepting that in P.iNOP^.\ the palleal
impression is interrupted. The animals, however,
differ in the two genera, the siphons being separated
near the extremity in Panopcea and united io their
extremity in Gl;/cimer!s. It would be impossible to
decide absolutely on the validity of this distinction,
which is probably one of degree, and therefore of
specific value only, without being able to examine
specimens of the siphonal integuments of every species.
P.\NOP^.\, tiPEt^GLERi, = Norvegica and its near ally P.
Middendorjii are quite northern in their range, reach-
ing only tlie northernmost parts of Great Britain, while
the other species included by Messrs. Adams in the

genus Ghjcimeris are tropical or southern, their range
extending to South Australia.

Alduovand's Panop^a. Shell large, elevated, sub-

Fuvjasii is narrower, nearly equilateral, and not at all
oblique ; Panopcea aitenuata is narrow, long, and
curved posteriorly, broad and reflected anteriorly.

//„/,. ? Recent.

M. Valenciennes remarks in his monograph in the
Illustrations Conchyologiques oi'Chemn., that the recent
shell figured in Plate II. of liis work and copied in ours,
is wrongly referred to this species. He states that it is
one of two specimens in the collection of Lamarck in the
Paris Museum, and that it is only a variety of Panopcea
Aldrovandi. Now it must be observed, first, that both
his shell and' one in the British Museum differ in
several respects from P. Aldrovandi, and secondly that
in describing P. Faujasii &s a fossil only M. Valenciennes
points out the same differences between the two species,
as those which exist between the recent shells. P.
Aldrovandi is narrow and pointed at the anterior side,
and broad truncated at the posterior, while the reverse
is the case with P. Faujasii.

We have no reason to suppose that this shell is
identical with the P. auslralin of Sowerby, or that the
last mentioned species ever attains a larger size than
the one represented in Plate VI. of this monograph.
M. Valenciennes having received a drawing of a
smaller specimen in the Cumingian Cabinet by Mr.
Sowerby, imagined it to represent the young of liis
gigantic species; an opinion which we cannot share.
Panopwa attenuata differs from the two preceding
species in shape and proportions, as will be seen from
the figure which we have copied.

The system of regular varices, often continued from
whorl to whorl in a half-spiral direction up to the apex,
the separation of the whorls in some instances, the
delicate colouring in others, and the e.xcpiisite sculpture
of many species, combine to render tliis one of the most
attractive of genera. The geographical distribution of
the genus is world-wide, and many individual species
have a very wide range indeed. China and tlie
Philippine Islands produce a large number, and a few
are found in Great Britain and more northern localities.

Acrilla gracilis, A. Adams.
ffab. Mouth of the Indus.

The name gracilis having been already applied to
another Scalaria, cannot be applied to the present
species if included in the genus. Would it not be bettor
in separating small groups from old genera, to avoid
using specific names already applied to shells belong-
ing to those genera ? A crilla may be a very good
genus, but its adoption should be left optional, by
not using a specific name already occupied in the old
genus.

A pretty little species, the thin varices of which
almost disappear in the middle of the whorls. The
description of this shell as Scalaria delicatula, was
published in the proceedings of the Zoological Society
in the year following that in which S. delicatvlay

Sowerby.
IJab. Black River Bay, ^Mauritius.

The sculpture of this little shell is e.xquisite. the
flattened ribs being fringed on one side with an angular
fluting which leaves little distinct perforations against
the back of the adjoining rib. There is au obsolete
tendency to the same arrangement of sculpture in
Scalaria varicosa and S. abbreviata, which belong to the
same group, but are not nearly so narrow and acumi-
nated, and have not the whorls so laterally compressed.

Scalaria rariscost.\ta. This exquisite specimen was
dredged by Sir David Barclay, Bart., oflf Round
Island, Mauritius. The ordinary specimens give
no idea of the beautiful sculpture wliich belongs
to the shell when in perfect condition. Besides
the four larger ribs which in this specimen are
crowded in the last whorl, the whole shell is
sculjitured with fringed and aculeated lesser varices.

'i'he wanl of (level. jped lateral teeth in either valve

the genus ; and in replacing it we are obliged to apply
a new specific name, that of lamellosa being previously

The single species which composes this genus, presents
an assemblage of characters which make it dillicult to
determine its place. Having neither internal car-
tilaginous pit nor appendage, it certainly does not belong
to the genus Mija, with which it was formerly united.
Yet, as in Mi/a, Panopiea, ttc, the parts of the animal
not covered by the shell are provided with a wrinkled
coriaceous covering. It is a mollusc of littoral habits
and, as might be suggested by its appearance, belongs
to northern and arctic seas. In the general characters

Shell with a single muscle, inequivalve, [ilaited ir-
regular, fixed by the apex of the right valve ;
umbocs unequal, scarcely auriculated ; cardinal
area in the right valve small; two divergent,
transverse, cardinal teeth in each valve striated
transversely ; a trigonal liL'aineiitiferous pit in
each valve between the teeth.
Plicatula is a well defined genus of shells always to be
recognised by the teeth and folds. Eight species were
described in the latest Monograph, that of the The-
saurus by Sowerby. Of the remaining five, two have
been described since, and three are here jircsented.

The Philippines, Australia, New Zealand, and
the shores of Western America furnish all the species
described in this Monograph, with the exception of
Plicatuht Cei/lonica, and the little Pliatlula siiiiji/f.c
from China.

This species is more numerously and less divergently

occasionally divided near the margin, do not branch.
The depression from which the species was named is
prob.ably an accident of growth in both the specimens

Genus EMAKGINULA, LaiwuH-.

Testa jialdliformk, plus minusive conica, plenimqu,
ovata, apice recurvo, radiatim costellata vel sul-
cata ; costd vel sulcos dorsali in Jlxsurum vel it
simim parvum ad manjinem anticum dcsinenti.

Shell patellitbrm, more or less conical, generally ovate, |
with apex recurved, radiately grooved or sulcated;
dorsal rib or groove ending in fissure or small
sinus at the anterior margin.

In place of the " key-hole" at the apex which
characterizes the genus Fissurella, there is in shells of I
the genus Emarjinula a cicatrix forming a grooved
ridge, when distinct, running from the apex to the
anterior margin and terminating either in an incised
slit, or a more or less perceptible sinus. The Emar-
ginulce are iirincipally inhabitants of deep water, the
larger number being obUiined by dredging on the
shores of Australia, the Philippines and West Indies.
There are three British and several Mediterranean
species.

Species 1. (Fig. a, b, c, d, Mus. Brit., &c.)

Emap.ginula i'.ugusa. Etna, testa ovatd, oblique conica,

funda.

The rugose Emarginula. Shell ovate, obliquely
conical, rayed and painted variously with green
and brown, strongly cancellated with elevated,
distant, roughened radiating ribs, with smaller
interstitial ones, and concentric ridges ; margin
crenulated within, fissure deep.

The long array of synonyms here cited results from
the great variation of form and condition to which this
species seem to bo liable, and to the extent of wearing
to which the sculpture has been exposed in different
individuals.

Syn. l\.\NGi.\. Desmoulins.

This genus belongs to the Macira group, and is re-
markable for the cinieiform character of the anterior
lateral teeth, and for the deep central pit in the hinge
for the reception of the cartilage or ligament. None
of the species belong decidedly either to salt or fresh
water, but the type is from Lake Pontchartrain in
New Orleans, wliere it has been used as an article of
food, and three of the other species, which have much
thinner shells covered with a lighter epidermis, are
found in mud-banks in brackish water in the Gulf of
Mexico. One of the remaining two is from Guada-
loupe.

Genus KIMULA, Defresne.

Testa patelliforiMS, teniii, cancellata ; apice remrvo ;
(torso arcuato ; Jissiird simplici, inter apicem et
miirf/im-m intermedia.
Shell patellilbrni, thin, ctmccUuted ; apex recurved;
back arched ; fissure simple, intermediate between
the apex and the margin.

The recent species of this interesting little genus,
formerly known only in a fossil state, are, with the ex-
ception of one from Mazatlan, found in the Philippine
Islands, and first collected there by the late Mr. Cuming.

The gi-adation in the several genera of Fissurellidaj
is marked in the jiosition of the fissure. In Fissurella,
it is simply a hole in the apex ; in Ccmoria it is just
in front of the apex, leaving it entire and generally
pointed, and being vaulted over by a little septum on
the inside; in Cranopsis tlio septum half covers the
fissure on the inside, but the latter is removed to half-
way between the apex and the margin ; in Kimula the
fissure is in a similar situation, but has no internal
septum ; then in Emargimda the fissure, commencing
about halfway down the dorsal ridge, remains open to
the margin and graduates through many species in
commencing nearer and nearer to the margin until
it becomes lost in an almost imperceptible sinus. In
the genus Zeidera, there is an internal septum near the
posterior margin and a fissure, like that of Einarijiiudu,
in the anterior margin.

plate, like that of Grepidula in form, but perhaps more
analogous to the small vaulted lamina under the foramen

ginula, this curious little genus affords an interesting
example of the ever-varying forms of Nature.

TYPHIS.

Genus TYPHIS, Montfort.

Testa fusiformis, caimlifera, vwicosa ; varicibus utroque
anfractu tribus; anfraciibus angutatis, ad arigulum
ante utramque varicem tubam gerentibus ; tuhis
intus penelrantibus, ad apicem apcrth; canali
clauso. Opermlum corneiim, concentricum. vi/riro
subterminali.

Shell fusiform, with a canal, varicose; varices three
on each whorl; whorls angular, bearing a tube
before each varix at the angle ; tubes penetrating
within, open at the apex; canal closed. Opor-
cuhini horny, concentric with nearly terminal
nucleus.

A tube on the angle of the whorls in front of each
varix, sometimes joined to it, but more generally
distinct from it and placed half-way between the two
varices, forms the distinguishing character of the shells
of this genus. In other respects they do not differ
from Murices with three varices. The type species,
T. Soiverbeyi, is a Mediterranean shell. The other
species are from Western Columbia, Western Africa,
Japan, Borneo, and New Zealand.

SCINTILLA.

Genus SCINTILLA, J)cs/,„i/,s.

Moltuscum acepludum, l/iinusctilogtim. T<sta bivalcU,

/(Bviyatd, transversim snboi'ata, margine dorsali sen

ventrali /re(jueiiter hianti, canlo dentibus utruquc

valv'i duobtts divergentibtis postico nonnunquam

duplicato ; Ugamento parvo, lineari, intcrno. Im-

pressio pal/ii integta.

Mollusc acephalous, bimuscular, shell bivalve, smooth,

transversely subovate, dorsal or ventral margin

frequently gaping; hinge with two divergent teeth

in each valve, the posterior sometimes divided ;

ligament small, linear internal ; impression of the

mantle entire.

The shells of this genus difler from those of Galeomma,

in having a smooth, sunictinies, polished surface. The

mantle is reflected over the backs of the valves, as they

lie open when living. Pew of the Scintilla gape

widely as most of the Galeomma: do. The greater

number of the hitherto recorded species are from the

Philippines. Several are I'rom Australia, while Borneo,

the Mauritius, and Ceylon add a few to the number.

Shell more or less auriform, with small sjiire and large

Operculum orbic\ilar, thin, hnrny, many-wliorled.

It is a (jUestion of convenience whether this genus
should or should not include the shells separated under
the name of Stomatia. The differences in the shells of
the two genera are not great, consisting mainly in the
I)resent genus not being wrinkled at the suture, like
tlie Stom(iti(r, and not liaving jironiinent spiral tubercu-
lar keels. The presence of an operculum in Stomatella
and its absence in Stimuttia, would, if it eoidd be
established, be a very important distinction. The
typical species is from Torres Straits, and two or three
are Australian, but a ver}' large proportion of the
remaining .species find their habitats among the Philip-
pines.

Although, as to the keels, this shell would appear
rather to belong to the genus Stomatia, it belongs to the
present genus on account of the crenulated edge of the
whorls at the suture.

Genus STOMATIA, Ildbling.

Testa haliotoidea, vcl subtrochiformis, medio anfractus

nllimi spiraliter hicarinata ; carinis tuhcrculatis.

Spira producta, anfractibiis ad S7itura7n rugato-

pUcatis. Opercidum nullum.
Sliell haliotis-shaped, or trochiform, spirally keeled in

the middle of the last whorl ; keels tubcrculated.

Spire produced, whorls wrinkled in plaits at the

suture. Oi)ereulum none.

The distinction between this genus and Stomatella is,
that the shells of Stomalia have two more or less
distinct tuberculated keels in the middle of the whorls
and arc crenulated at the suture. The habitats are as in
Stomatella, the majority being Philippine. The type,
Stomatia phymotis, is a Red Sea shell, and its nearest
ally, 5. Aiistralis, affects the locality which its name
implies, besides being found in the Philippines.

The gcmis 3Iicroth, consisting of but a single species,
is hardly worth separating, the dictinction being the
singular one of the inner margin of the aperture being
continued spirally and visible to the apex.

whorl large, strongly plaited at the suture, ex- [

cavated below the plaits, then moderately gibbous,
thence sloped, bicarinate in the middle, keels
rather distant, nearly equal, sharply nodulous ;
wrinkled below the keel.

Differing from Stomatia phimotis in the narrower

species we include all the shells figured as varieties of

represents a very abnormal form.

here, however, as it is recognised in collections.

form and smootli surface, although some of tlio smaller
species have a somewhat more orbicular form. The
animals live among stones or on coral reefs between
tides. A large proportion of the species are the results
of the late Mr. Cuming's researches in tlie Philippines.
Australia and some of the Pacilic Islands contribute a
few.

Genus SOLEN, Liiinceiis.

Testa CBquivalvis, transverse clongata, recta, vel lente

Shell equivalve, transversely elongated, straight, or
slightly arched, more or less truncated, gaping,
with terminal umbones. Hinge elongated, with
one and two principal teeth. Ligament external.
Anterior muscular imi)ression elongated. Palleal
impression with a square sinus.

There would seem to be no sullicient reason to
separate generically the straight from the curved razor-
shells. United, they form a capital genus, distinguished
from others of the family by having terminal beaks. The
shell is also divided into two more or less distinct areas
by a diagonal line from the apex at the anterior to the
posterior lower corner of the truncated [uisterior
extremity.

The habits of the Solens are peculiar. They furm
deep burrows in the sand, into and out of which they
spring with amazing rajiidity by a sudden contraction
and expansion of the foot. They can also leap forward
with great power. They are found in most tem-
perate and tropical countries, but no country possesses
many species. On the coasts of Britain we have
several well-kno\vn species ; Mr. Cuming found several
in the Philippines, but most of them are scattered singly
in almost as many countries as species.

Genus ADEORRIS, Wood.

Testa orbicularis, depressa, umbilicata, alba ; anfrac-

Shell orbicular, depressed, umbilicated, white ; whorls
few, last large. Aperture large, peritrcme inter-
rupted. Operculum none.

The little wliite shells Ibrming thi.s group differ from
Ci/closlrema;, principally in having a more depressed
and less conical form, and in the edge of the aperture
being interrupted instead of continuous. The genus
was created for the little bicarinatod British species.
Most of the others have been collected eithrr by Mr.
Cuming in the Philippines, or Mr. Arthur Adams in
Japan. But the most beaulLlul species is Aihurhis
Anqasi from AustraUa.

Shell depressed, white, polished, solid, rarely spirally

striated ; umbilical region covered by a callus ;

aperture laterally produced, distant from the axis.

Tiie difference between this genus and Adeorbis is
that while shells of the former are widely unibilicated,
those of the latter have the imibilicus filled up by a callus.
The mouth also is laterally produced and out of axis.
The localities of the few species known are as remote as

The late Mr. Broderip described two shells of this
small genus, including them in Scutella. Hut although
the animal is not known, the structure of the shell makes
it probable that they belong to the family of the
Slomatellinoi ; and that they bear the same relation to
that family as the Ancyli do to the Lymneadw.

Two Pacific, one Philippine, and one other species,

Uniting tlie group rcpresente<l by Sulcn CulteUus,
and that represented by Solen radi<ilus, the latter
having an internal umbonal bar or rib, in one genus,
we have all the Solenidce, excepting S. legumen,
divided into three genera — viz., Solen, including the
razor shells, whether straight or curved, with the beaks
terminal ; Cultkllus, including Siliqua, or the " radiata' '
group, which, with or without the internal rib, having
the beaks near one end, or at least nearer than the
middle, and Solecurtus, including Macha, Siliqu.\hia,
Novaculina and Pharella, having the beaks centi-alor
nearly so.

Like true Solens, the species of Cultclht.t are found
in the sands of nearly all climates.

Shell orbicular, depressed, broadly umbilicated ; spire
small, whorls spirally and concentrically ridgod or
sulcaU'd. Aperture entire, not pearly, margin
acute.

Some of the smaller species of DelpJiinula resemble
these little shells, which, with Adeorbis and the sub-
genera of both make a natural group. The difference
between the two genera is that Cydostrema has more
external sculpture and a wide umbilicus, which in
Adeorbis is wanting. Of the twenty-three species
included in this genus and its subgenera Daionia,
Tubiola, Microlheca, and Mot-chia, a dozen were found
by Mr. Arthur Adams on the coasts of Japan, half-a-
dozen more wore collected by the late Mr. Cuming
amongst the Philippines, leaving five or six for such
widely distant localities as Britain and Australia,
China and California, &c.

Genus CHILIXA, Gray.

Testa fluviatilis, tenuis, ovata, ventricosa, epidermide
olivaceo induta, ■plerumque fasciis maculisque picta ;
aperiura oblonga; columella incrassata, plusminusve
plicata; lahio externa acuta.

Shell fluviatilo, thin, ovate, ventricose, covered with an
olive epidermis, generally painted with bands and
spots; aperture oblong; columella tliickeiied,
more or less plicated ; outer lip sharp.

Sy„. D(.mhei/u, Orbigny. Mi, Lea. FotamophUa,
Swainson.

Although some species of Limnixa approach the
ChiUnce in form and habit, and are also freshwater
molluscs, there is no difficulty in distinguishing sheila
of the two genera. The shells of the Cl'ilince are
always striped or spotted under the epidermis, and the
columella is thickened, more or less plaited. All the
species inhabit the warm regions of South America.

This species has very close relations with Physa
tabulata of Gould. The chief difference consists in
the rounded angles of the whorls in the latter and the
distinct square angles in the former. These characters,
however, are somewhat varied, and some specimens in
each approach very nearly to each other.

" For the dear God, who loveth us,
He made and lo^^tth all."— Coleridge

Splniiiius ri. I.

t

Vbic™t Brook, aiy* Sou tmi'

S 0 L E C U R T U S.

Genus SOLECURTUS, Blainville.

Testa transverse oblonga, bimuscuhsa, utrinque truncata,
hians ; medio planulato, umhonibus ceiitralibus vet
subcentralibus. Impressio pallii late sinuata, tiga-
mentum externum. Denies cardinnles uncinnati.

Shell transversely oblong, bimuacular, truncated and
gaping at each end ; lluttened in the middle, with
central or subcentral umboes. Palleal impression
broadly sinuous. Ligament external, cardinal
teeth hooked.

Our Solecu7-ti will be found to include the genera
Macha,Pharella, Siliquarki, and Novaculina of modern
authors; so that, with the exception oi' Plianis, all the
Solenida; are divided into, first, Solen proper, with the
umboes terminal ; .second, Cultellus, with the um-
boes much one-sided, although not terminal ; and
third, SoLECfRTUS, with umboes central, or nearly
central. And this distribution by the position of the
hinge is pretty generally concurrent with other charac-
ters of the shells. The geographical distribution of
these, like that of other Soknidce, does not appear to
be guided by any general rule. We have a couple of
species on our own coast ; Novaculina is found in the
mud of Indian and Chinese rivers. North and South
America, Africa and Australia, contribute each a few
species.

Genus PETRICOLA, Lamarcl:
Ti'sta ovala, plerumqne alha, mjiiiralris, epiderviidc
lenid imluta, interdiim radialim co^tata; latere
antico hrevi, rotiiiH/o, lntere postico producto,
frequenter attenwito. Cnrdo tilnique valca bidenlido ;
li/jiinientum breve, externum. Imprcsiio pal/ii
postice sinuata.
Sliell ovate, generally white, eqnivalve, covered M-ith a
thin epidermis, sometimes radiately ribl)e(l ; an-
terior side sliort, rounded, posterior side prmhu-iil,
frequently attenuated. Hinge with two torlh in
each valve; ligament short, external. I'allcal im-
pression posteriorly sinuous.

Like the Venerupes, these are rnck-inliabiting shells,
the animals attaching themselves by means of" a byssus
within holes and crevices, to whicli the .shells are often
found to conform their shape, thus becoming irregular.
Generally the Petricola; are longer than the VenerupeS;
tapering towards the posterior, and in their sctdpturc the
radiating predominate over the concentric ribs or stria;.
Western America seems to jiresent the more favourite
resorts to these Mollusks, although the shores of the
Pacific, the Mediterranean, and Red Seas posse.ss some
s])ecies. India and Australia are not without them.
Besides seeking holes in rocks in which to reside they
exerc-ise the power of enlarging, if not entirely excava-
ting new ones, hard stones and corals being sometimes
pierced by them.

Hal,. ?

This shell was named by M. Deshayes from a speci-
men in Mr. Cuming's collection. Notwithstanding the
variations to which shells of this genus fere subject, the
extreme attenuation and finer sculpture in this case
may be considered sufficient to distinguish the species
from Petricola jiltoladifoniiis.

to this shell.

The external appearance of this well-known species
is that of a Pholas ; and it is only the absence of the
subunibonal processes and accessory valves that dis-
tinguishes it, as far as the shell goes, from that family.

I cannot identify the specimens of this shell in the

Genus ASTARTE, /. Sowerhy.

Testa eequivaUns, inmquilateralis, subovata, vel orbicu-
laris, vel subtrigona, ■plcrumqv£ subcompressa ;
concentrice riigata, epidermide crassa induta, dausa.
Impressiones muscidares duo;, magnce, snhreniformes.
Imprcssio pallii integra. Cardo iitnhjiie valcd

Shell equivalve, inequilateral, subovate, or orbicular, or
subtrigonal, generally subcompressed ; concentri-
cally wrinkled, covered with a thick epidermis,
closed. Muscular impressions two, large, rather
kidney-shaped. Impression of the mantle entire.
Hinge tridentate in each valve. Ligament
external, with dorsal area and lunule excavated.

Sijn. Crassina, Lamarck. Tridenta, Schum.

The shells of this genus are not liable to be con-
founded with those of any other, the several characters
included in the description being pretty constant in all.
The minute Asfarte trigoimlaris is the only exception,
and is very abnormal in form. The concentric
wrinkles have in most species a tendency to become
less prominent towards the centre, and even to dis-
appear altogether towards the margin of the shell All
the species, excepting the Mediterranean A. Jiisca,
inhabit northern seas ; Norway, (ireenland. North
America, Ac, being the chief places in whose sandy
shores they burrow.

The sliells of this genus are found in holes and
crevices of rocks, where they are fixed by a byssus
passing between the gaping valves. It is rather difficult
to distinguish some of the species from the more irregu-
lar rock-inhabiting Tapes on the one hand, and the more
Tapes-like Petricols on the other. The concentric
lamina, however, are the more prominent in this genus ;
whereas the reverse is the case in the Petricolie, and
tlie posterior side is generally truncated, and does not
tend to end in a point. The Venerupes are more
numerous in northern and temperate climates; many
species are European, being found in Scandinavia and
the British Islands. There are, however, some species
in Australia, and some in the Pliilippines.

The distance of the ribs or sulci from each other
varies in different specimens and in different parts of
the same shell, but there are generally a few broader
ones a little in front of the posterior oblique angle.

The subgenus Kennerlia is founded by Mr. Carpenter
upon the species Pandora glacialis and another or two,
which are said to have an ossicle. This ossicle seems
to me to be only a thickening of the sides of the liga-
ment pit ; in which case, the generic description of
Pandora by Adams as hav'ng "no free ossicle" would
be correct of all the species including the al>ove
mentioned. It is quite possible that an examination of
more specimens might modify my view of this mutter.

The Pandorae burrow in s;ind and mud at con-
siderable, but varying depths. Britain has two species ;
other species arc found northwards at Spitzbergen,
centrally at Panama, and southwards at New Zealand.
The number of species has not very largely increased
since the publication of the late Mr. G. B. Sowerby's
monograjih in the Species Conchyliorum ; that is to
say, it has not done so in proportion to many other
genera during that period.

distinguislied from those of Trichotropis, not only by
the lighter texture, and usually more ovate form of the
shell, but by the absence of an umbilicus.

Hab. N. America.

In Trichotropis Borealis the ribs are thick and equal.
In this species, otherwise much resembling it, the three
upper ribs are thin, and the four lower ones still thinner.
The entire shell is also thinner, and the umbilicus
narrow.
