IN off ering to the public their work on the G enera o f
Recent M ollu sca,” the Au thors believe they are supplying a
wan t in this branch of Z oology, especially as ac tive research
is now b eing made in to the struc ture and h abits of the
animals that produce the beautifu l shells so much admi red
in the cabinets of C onchologists .
They have endeavoured,as far as the presen t state of
knowledge on this subjec t would permi t them, to group the
G enera in accordance with their natural affi nities, and th eytrust th at
,from the care with which they have consulted
every original source of information, the work will prove a
correc t and useful guide to those who desire to becom e
better acquainted with this interesting division of the animal
kingdom .
T he A uthors desire to acknowledge their obligations to
D r . Gray , M r. S . P . Woodward, and especially to M r .
Hugh Cuming, who , with his accustomed love o f science,h as afforded them liberal access to his unrivalled collection,and freely imparted to th em much valuable information
relative to th e habits and local i ties of various genera .
With regard to th e il lustrations,the Authors may add,
that many are derived from drawings of the living an imals,

and wh ere not origina l . have b een faith fu l l y copied or
(lll t‘L‘tl from the various worksquoted . For the fi gures o f
the shel ls . recourse has been h ad in almost every instance
to the objec ts themse lves .

M olluscou s anima ls have su fficient maternal instinc t
to select situations for 0 3 3190 33750 73 most advantageous to
the development o f the ir eggs . T he Amp ullariz’
dce de
posi t their conglomerate egg-masses on stones and frag
ments of w ood in the sha l low parts of ponds, where the
eggs are exposed to the ful l pow er of the sun . The
D or ididce and L imnocia’oe glue their ova together and
a ttach them in gelatinou s bands to floating bodies, tha t
they may neither sink beyond the influence of the solar
hea t, nor be dispersed by the a c tion of the w aves . T he
Ianflm’
na and A rgona uta bear theirs constantly abou t them,
the first a ttached to a vesicu lar floa t, the second con
ta ined in a fragile shell . T he Ca rocolla conceals hers
under loose bark . T he P y t/n'

thick- shelled E nlimi , tha t live u pon the ground, deposit
large ova l ca lcareous eggs among the leaves, w hile those
lighter and more highly co loured spec ies, tha t live upon
the trees, glue their coriaceou s ova to the under su rface
of the leaves, and some among them have suffic ient in
genu ity to rol l up the edges o f the leaves , cement them
together, and form kinds of nests or cradles for thei r
tender progeny .
4 MOLLUSCA .
The hard or soft a lbum inou s capsu les, or ootheca ,which
defend and protect the ova of mollu scous anima ls,offer
a variety of forms . The eggs o f the Cepha lopods are
e ither agglomerated into masses l ike bunches of grapes,as in the Cu ttles, or into long garlands and strings, as in
nearly all the S qu ids. The ova of marine Gasteropods
are enveloped before exclu sion in mucou s capsu les, in some
cases soft, flex ible , and transparent,w hich harden more or
less by contac t w ith the w ater , and a ssume forms pecu liar
to tribes and genera . T his nidu s or egg-nest is some
times simple, but often compound,
each compartment
conta ining many ova . In M az z a the cel ls are o f a
flattened sub-pentagona l form,adhering together and piled
one upon the o ther,each compartment conta ining from
tw enty to thirty embryos . The ooflzeoa of P urp ura 7m
mastoma are yel low or rosy, elongated , quadrangu lar, and
trunca te a t their ends, and are fixed in groups upon
the rocks . The nidus of P . lap illus, which E llis ca lls
the sea -cup, is in the form of an elliptica l vase supported
on a short stem . T he egg-capsu le o f N ep tunea N orw
gz’
ca is a ttached, iso la ted, hem ispherica l , w ith a thin,
coriaceous membranous coa t . In Buccz'
num unda tum the
nidimental capsu les are aggregated in large irregu lar
masses, each case being oblong , one side convex , the
other flat . The nidus of N assa reticula ta is in the form of
a compressed pou ch , w ith a short peduncle and an Openinga t th e top . T he sma l l nidimental cells of the cow ry
are aggrega ted in a fla ttened group . In Bursa they
are in numerou s groups very c lose together, long , com
pressed , enlarged a t the end, w ith one or tw o keels .
In Trophon they are sub-cylindrica l and trunca te a t
the upper end,and deposited in groups on stones and
MOLLUSCA . 5
In Rap a tennis the nidimental capsules are a ttached
in regu lar linear series to portions of decayed w ood ; they
are of a fla ttened subconica l figure , adhere by the apex ,
and have the base emarginate . In .Murex endica the
cases are tricarinated,one o f the keels being bifi d. In
Tritom’
um sca ber they are fla ttened and quadrangu lar, w ith
fou r keels . In Conus cap itaneus they are cu rved , w i th a
dorsa l keel , and w i th the free end fa lc iform . In Busy cum
afi ne the capsu les are arranged in a long string ; they
are ova l , fla ttened, keeled, the edges angled, and a ttached
by a short pedunc le .
T o enumerate a few more examples of the 0 0 1773666 of
marine Gasteropods, — in A canflzina unicornis they are
cyl indrica l, and adhere by slender peduncles in densely
packed masses . In Chorus monoceros the somewha t
columnar egg-cases a re united by slender peduncles in
a large rounded mass, the capsu les having l ids which the.
young pu sh off . In Volnta they are hard, vesicu la r, and

branchs by Lové n and M ilne Edwards . T he Biva lves
a lso undergo a metamorphosis, bu t the C epha lopods do
not appear liable to these changes .
T he larva is a lways enc losed in a little,transparent
,
nau tilo id , ca lcareous shel l , provided w ith an opercu lum , and
it sw ims freely through the w a ter by means o f tw o fi n
like lobes fringed w ith long c ilia . Instead of tentacles
it has tw o vei ls shaped l ike ears,which disappear a t a
later period ; the eyes, the ears, the liver, and the vent
are as in the adu l t . T his is the first stage . In the
second stage it is still enc losed in a shell, but the mantle
has become detached and covers the viscera , the foot is
enlarged and projec ts beyond the opercu lum , and the
head has two short conica l c iliated tentac les . In the
third stage the shel l has fa llen off , and the genera l shape
is tha t o f the parent, but the ve i ls stil l rema in . In the
fou rth stage the anima l begins to craw l by means of its

and a spiny tongue . T he last stage is marked by the
fa l l of the fronta l veils, and the completion of the ten
taeles and gills, thu s conc luding the metamorphosis .
The young b iva lves are hatched in the gills o f their
parents, and have a sw imm ing disc , fringed w ith longc ilia , and furnished w ith a slender tentacu lar filament .
The labial palps nex t become deve loped, and the disc
gradua lly disappears . T hey then acqu ire a foot,and are

In a work like the present , w hich is intended to be
entirely Zoologica l , the anatom ica l and physio logica l de
ta ils are pu rposely om itted . T he z oological pecu liarities
o f the adu l t mu st now b e briefly considered .
The [Lead in some fam ilies is permanently ex tended and
proboscidiform , as in L ittorinidae and M elaniiolce . In the
predaceou s Gasteropods it is furnished w ith a mu scu lar
trunk,which is often entirely retractile ; but in the phyto
phagou s tribes it is supplied w ith jaw s for compressingthe food . The head is often inconspicuou s, as in many
M urieidce ; in some i t is long and flat , as in Bursa and
Syeotypus ; in some it is produ ced and cylindrical,as in
Cassiolu lus ; in some broad and flat,as in Bulla and
L unicep s .
S ome M ol lusks are blind , as the E olis, Glaucus, and
D or is, and, in the adu lt sta te, the Oonelzifera . The eyes
make their first appearance as colou red specks on the
upper surface of the neck, as in Ap lysiiclee, or on the head,as in Bulliclce . In their most perfec t form they have
iris,pupil , crysta l line lens, choro id, vitreou s and aqueou s
humours, and cornea,as in Oymbium, Helix, S trombus,
and the C epha lopods . T he ey es are tw o , symmetrica l ,u sual ly at the sides of the head, sessile or peduncu lated .
In Ha liotis, N er ita , Turbo, Helix,and Ouclziclium, they
are a t the end of long pedunc les , or 0mma top710 ra . In
M urieioloe and Cyp roeicloe they are extended on tubercles,connate w ith the tentacles ; but in S trombioloe they are
free . The vision of M ollu sks varies w ith their habits.
In the Biva lves and T unicaries the eyes are readily
dispensed w ith , the animals being either fixed or nearly
mo tionless . In the P ec tens, how ever, which sw im rapidly
by tlie flapping of the ir va lves,the eyes are numerou s
and peduncu lated , and situated at the bases of the pallia l

mechanica l organ for the a ttrition of food ; gusta tory villi
have , how ever, been detec ted on the tongue of the C epha
lopods . In the biva lves the mou th is suppl ied w ith tw o
soft membranous pa lps, and in the Brachiopods w ith tw o
c ilia ted arms . The mou th of the Cepha lopods is armed
w ith horny jaw s, w hich act vertically l ike the mandibles o f
a b ird . In the Helioiclce there is only an upper jaw , and
in the L imnceiclce there are two accessory la tera l jaw s .
T he tongue is a membrane covered w ith hooks or prickles,w hich are arranged differently in the different families .
I t u su ally forms a triple band, of w hich the centra l part
is ca lled the ra chis and the latera l tracts p leura . The
teeth on the m iddle part are termed centra l ; those on
the pleu rae are named uncini or la tera ls ; it is sometimes
broader than long , as in Tr itonia and D or is, or it is ellipti
cal and spoon-shaped, as in the Helieiolce . In o thers it
i s riband-shaped and mu ch longer than the body, in which
case i t is reversed a long the gu l let and coiled spira lly in
the stomach . In the carnivorous families the tongue is
forked and fleshy, armed w ith sharp cu rved teeth and
placed at the end of the muscu la r proboscis,while in the
phytophagou s tribes it is very long and spiny, for filingtheir food to pieces . T here is no tongue in the Tunica ta ,w hile in the biva lves i t appears in the form o f a gastric
dart, a cartilaginous stiliform body enclosed in a shea th
w ith a tricuspid free extremity and a ttached to the sides
of the stomach .
In the D oris and Ap lysia there are no jaws,and the
cartilaginou s surface of the tongu e i s covered w ith cu rved
spines . In the P a tella the tongue is o f grea t length, and
is covered w ith transverse row s of spiny teeth . In the
Cep’li alopods i t is short and muscular, and covered w ith
row s of spines. M . Lové n has demonstrated tha t im
MOLLUSCA . 1 1
portant generic and specific characters may b e derived
from a carefu l exam ina tion of this organ . In the Bullialce
the rachis of the tongue is unarmed, and the triturat ion o f
the food is effected by means o f calcareou s pla tes in a
muscu lar giz z ard .
The organs of toueil in the M o llusca are in the form o f
soft fleshy tentacles w ithou t joints . Usua lly in the Gas
ter0 pods there are tw o arising from the sides of the head,
sometimes free, as in the snails, sometimes united w i th the
eye-pedic les , as in the M urices, and sometimes partia lly
free,as in the S trombs . In the T unicaries and Biva lves
there are numerou s tentacles placed around the breathingapertu res and margins of the mantle . A dditiona l pa irs o f
tentac les at the sides o f the mou th,called bucca l append
ages, and a lso pro longa t ions of the lips, termed labia l
appendages, are often supplied , a s in the Ap lysiiclce and
Oneltidi ida , and occasiona lly the exposed su rface of the
mantle exhibits fleshy tentacu la r ex tensions, which serve
to appriz e the owners o f danger . In the P teropods and
Cephalopods long tentacu lar a rms are ex tended round
the head for the more accu ra te perception of tou ch, and
in the Trocltiola and Turbinialze the sides o f the foot are
furnished w i th tentacu lar fi laments for the same purpose .
T he f oot is a muscu la r organ u sua lly developed in pro
portion to the locomo tive pow ers enjoyed by the anima ls ;i t is w anting in the oyster
,which is fixed, bu t in the sna il
it is long and broad . By means of a mu scu la r foot the
P liolacliclce and S oleniclce bu rrow in the mud, the L imnaeas
sw ims at the su rface of the water, and w ith their grooved
and linear foot the Nudibranchs c lasp the stems o f floa tingfuci . In the A talants i t is compressed la tera lly into a
sw imm ing fi n- like organ ; and in the D olium i t is some
times greatly expanded by the introduc tion o f w a ter .
1 2 MOLLUSCA .
M any M o llu sca are furnished w ith numerous complica ted
canals which communica te w ith the su rrounding flu id and
serve (as in D olium) to distend the foot by the admission
o f w a ter . In Cyp rcea there is a long sl it in the so le of
the foot near its m iddle . In Ha liotis there are tw o or
three pores at each extremity, and in D oris, Ap lysia , and
Bulla there is a series o f o rifices placed round its edges .
In many fam il ies the sole of the foot is imperforate , as
in Turbo, Troenus, M urex, and P urpura , w hen the w a ter
enters by a pecu liar orifice near the vent,from whence
i t finds its w ay into the cana ls that rami fy through the
foot . The use of this system of aquedu cts, as D r. J ohn
ston has termed it, is to distend the various organs and
render them more fi rm and capable of mu scular exertions .
T he dorsal surfa ce o f the foot secretes certa in horny
or ca lcareou s layers, w hich constitu te the opercu lum, a
flat body, which c loses the mou th of the shel l when the
anima l is retracted . When the anima l is too large to
enter the shell , the opercu lum is absent, as in Ha liotis,
Gena ,and S toma tia , or is rudimentary , as in S igaretus.
‘
When the anima l is ent irely retractile w ithin the shell, the
opercu lum is larger . I t is round in the vegetable-eatingtribes, as in Turbiniola , and ungu iform in the flesh-ea tingtribes, as in M ur iciolaz . When the anima l envelopes the
she ll in lobes of the mantle , there is no opercu lum, as in
Cyp rcea , M arginella , Cyp rceoassis, and Sy cotyp us. Whenthe foo t is large the opercu lum is sma ll , and vice versa.
In some tribes the O percu lum is stony, as in Turbiniclce,while in others it is horny, as in Troeltialce . In o ther
cases it is stony, in one genu s of the same family, as in
N a tica , and horny in another , as in L una tia , or rudimen
tary, as in S igaretus. The opercu lum consists of a hard
ened portion of the skin, the cel ls o f w hich are filled
MOLLUSCA . 1 3
either w ith horny or ca lcareous matter . S ometimes an
Opercu ligerous lobe is developed around the opercu lum ,
and secretes a coa ting of ename l on the upper surface,as in Imp era tor , Turbo, and P basianella .
The opercu lum may b e annu lar and mu ltispiral , as in
the Troebiolee ; annu lar and pau c ispiral , as in M odulus,
E ebinella , S toma tella , andE uebele ; o r subannular and ovate ,
as in D istortio, Bursa , and M urex ; or subannular and
ungu icu la te, as in S trombus and Harp ago. I t may be
a lso Spira l and ova te , as in L ittor ina and the N a tieicloe
or spira l and orbicu lar,as in Tymp anotomus and Cer i
tbia’ea . The most singu lar varia tions of this organ are
in Hipp onya , Ca lyp troea , and Ianthina . In the two
former genera i t is a ca lcareous plate , and fixed to foreign
bodies, w hile in the la tter it is vesicu lar, and serves as
a float .
T he mantle is a muscular sac, w hich envelopes the body:
I t is u sually open in front, and secretes a shell, w hich
serves to protec t it . S ometimes the shell is conta ined in
the substance of the mantle, as in the C epha lopods and
Ap lysi iolce ; and sometimes the edge of the mantle is
ex tended and covers the shell , as in Cyprceiclce. T he
front edge is often simple and thickened, as in Trocbiclce ;furnished w ith fi laments, as in S trombicla ; or w i th com
plica ted fringes, as in M ur ioiola . In some tribes,as in
the phytophagous Gasteropods, the margin i s entire ; bu t
in the z oophagou s tribes, it is pro longed into a tube or
siphon .
The she lls of M o llusca have been compared to the
skeletons of Vertebrate anima ls ; bu t they are obviously,
a s show n by D r . Carpenter nothing but portions of ca lc i
fi ed skin . The mantle, w hich is a mu cous membrane,
throw s off an epithelium , w hich secretes

matter in its cells, and becomes hardened into a layer
of shell . The ep idermis, like tha t of other anima ls, is
inorganic , and cast o ff occasiona lly by the an ima l . T his
ca lcified epithe lium or shell-struc ture is formed ei ther o f
p r isma tic cells, filled w ith ca lca reou s ma tter, and arranged
perpendicu larly in layers, or it is composed o f thin
membranes, w hich deposit the shelly matter on their
su rface . When the membranes are finely pla i ted, and
the fo lds lie one over another, the nacreou s or pearly
appearance i s produced . S om etimes the membranou s
she l l-stru ctu re is traversed by tubes, the direc tion and
distribu tion of which va ry in different genera , bu t u su
a lly they form a netw ork . O ccasional ly the prisma t ic
she ll-stru ctu re i s very large , and the cells are hollow ,
as in the Budistes among Biva lves ; this constitu tes the
caneella teal shell-stru c ture .
The marg in only o f the mantle has the pow er o f givingorigin to the outer layer of the shell, w hile its w ho le
su rface may genera te the inner . A s the anima l increases
in dimensions, each new interior layer of she l l projec ts so
far beyond the preceding , tha t the new border composed
of the ou ter layer is simply jo ined on to the ma rgin o f the
former one . The co lou r is situa ted a lways in the ou ter
layers, and is fu rnished by glands in the edges o f the
mantle ; and the secretion of the co lou ring-matter, beinguninterrupted, or interrupted at regu lar interva ls, produ ces
all the stripes and spots which serve to ornament shells .
The shel l is mou lded on the mantle of the anima l, so
tha t some of the most distingu ishing generic characters
may be detected from its exam ina tion . The edges of the
mantle are o ften deve loped into fringes a t certain periods,and form the spines and ribs
, and all the irregu larit iesseen 0 the surfaces o f she l ls .
MOLLUSCA . 1 5
In the Gasteropods the shell is somet imes w ant ing , as
in the N udibranchs ; in others i t is very smal l and rudi
mentary in the skin of the back, as in the Ap lysiidce ;
and in some it only covers important o rgans, as in Ca ri
naria and Testaeellus . In the Obitoniolce i t is composed of
severa l pieces, bu t in the genera lity of cases it consists of
a hollow cone c losed a t the apex , and more or less spira lly
rolled . In P a tella and D enta lium the cone i s nearly
stra ight . In Vermetus and S ca la ria i t is spira l . In
Helix and Ooretus the spira l whorls tou ch . In some
the spira l is eleva ted, in o thers depressed ; in some
smoo th on the ou tside, in o thers Spiny or tubercu lar.
In the carnivorou s tribes the apertu re of the cone is
emarginate and produ ced into a ca lcareou s tube, which
lodges the siphon or muscu lar prolongat ion of the mantle
that conveys the w ater to the g ills ; bu t in the herb i
vorou s orders it is u sually round and continuous .
The M o llusca , l ike all o ther anima ls, are liable to
a ttacks of pa rasitic epiz oa and ento z oa . The Tbetis
fi mbria is infested w ith the Vertumnus tbeeia'icola of O tto .

The shel l secreted by the female A rgonau t is thin

The dorsa l pa ir of tentac les is considered to be expanded,
form ing the hood which c loses the apertu re of the shell ;the tentacles are lamella ted on their inner su rface , and
are retracti le w ithin sheaths which correspond to the e ight
ordinary arms of the cu ttle- fi shes . Besides these, there
are fou r ocu lar tentacles, which are supposed by P rofessor
O w en to be instruments of sensa tion,like the tentacles o f
D oris and Ap lysia there are , moreover, fou r groups of
labia l tentacles, tw elve or thirteen in each group, which
appear to answ er to the bu cca l membrane of the dihran
chiate C epha lopods ; the mandibles are su rrounded by a
fleshy lip . The respira tory funnel , or siphunc le , is formed
by the fo lding of a thick mu scu lar lobe behind the hood,or foot — l ike appendage , it forms an expansion which covers
the black part of the shel l . The habits o f the Nau t ilu s are

SPONGIOBRANCHIA . 63
In this family the genera are distingu ished princ ipally
by the gills, which in P neumodermon are lobed, and at the
hinder part of the body ; in Sp ongiobranchia they form a
prominent ring nea r the end of the body in Trichocy clus
a c iliated ring round the m iddle O f the body and in Be
lagia they are indistinc t or w anting .

CLASS GASTEROPODA .
HEAD distinct, furnished w i th eyes and tentacles . Body
u sually protected by a conica l or spiral shel l . Low er part
of body formed into a thickened, expanded, creeping disk
or foot .
T he Gasteropods, so termed from the c ircumstance o f
their craw ling on their bel ly, may be known from the other
M o l luscou s c lasses by the head being a lw ays present and
provided w i th eyes and tentacles, the former being e i ther
sessile , or on the ends o f ommatophora or peduncles, which
are e ither free or connate . T hey constitu te by far the most
numerou s section o f M o llusks, and comprise not only a ll
those tha t l ive u pon the land , but likew ise a very large pro
portion of those tha t breathe by gi lls and inhab it the w a ter .
W ith the exception of the a ir-brea thing fam ilies, the
Gasteropods are different ly shaped w hen very young , the
fry having c ilia ted w ings on the sides o f the head by which
they sw im freely abou t,and the body conta ined in a l ittle
c lear spira l Shell w ith the aperture c losed by an opercu lum .
A s they grow , how ever,the head-w ings are absorbed
,
the foo t or creeping disk becomes developed , and the
Shells assume the forms pecu l iar to the different genera .
In the N udibranchs the shel l fa l ls off and disappears when
the locomo tive foot appears,bu t sometimes it rema ins ru
dimental w i thin the fo lds o f the mantle . In their adu lt
GASTEROPODA . 67
condition they are e ither preda tory and carnivo rous, or prefer
a vegetable diet , and inhabit, somet imes the high seas, as
the Nucleobranchs ; somet imes the forest trees and su rface
of the earth , a s the P u lmonifera ; somet imes the lakes
and rivers, as the Amp ulla r iidae, and sometimes the shallow
creeks and bays, a s the z oophagous tribes genera lly . In
the P rosobranchiate division the adu l t anima l is provided
w i th a shelly covering , u sual ly more or less spira l, w ith
the apertu re e ither ent ire , or notched,or produced into a
cana l in front ; in the O pisthobranchiate division the body
is e ither naked,or w i th the g il ls pro tected by a shel ly
va lve , which is external,or concea led in the mantle . In
the Nucleobranchs or the Heteropoda o f Lamarck, the
foo t is modified for sw imm ing , as the anima ls are pelagic,and the shel l is often very thin, rudimentary, or w anting .
The animals of the P u lmoniferou s division are u sua lly en
cased ia spira l shells, which , in some tribes, how ever, are
rudimentary, and in others a l together w anting .
In the branchiferou s Gasteropods the form and position
of the gil ls vary very considerably and offer excellent
charac ters for defining the orders ; in the Nucleobranchs
they form a projecting comb-like tuft ; in the N udibranchs
they are exposed upon the su rface o f the back ; in the
T ec tibranchs they constitu te a plume betw een the mant le
and the foo t ; in the P rosobranchs, which inc lude most of
the P ectinibranchs o f C uvier, the gills, u sua lly unsym
metrica l , are in the form o f tw o comb — like o rgans in a
cavity over the back protected by the mantle ; whi le in
the P u lmoniferous tribes the place o f the gills is occ a
pied by an air-sac lined w ith a vascular net-w ork, which
ac ts l ike a lung . T he modificat ions which the foot, the
mantle , and the o ther organs undergo , w ill be mentioned
under the variou s groups which these pecu liarities crea te .
68 PRO SOBRANCHIATA .
The shells of the Gasteropods, those e legant ca lcareou s
cones mou lded on the body of the animal , and justly priz ed
for their varied ma rkings , exqu isite scu lptu re , and gracefu l
contou r of form,most frequ ently a ssume the shape o f a spira l
co il . The spire is somet imes on the same plane , a s in the
disco ida l Coretus ; or produ ced , as in the turreted M ega
sp ira ; or loosely co iled,as in the irregu lar Vermetus ; or
unrolled and partly stra ight , as in the smgular Camp ulotus ;
or it may be invo lu te , as in the po lished Cow ry ; or ta
pering a t ea ch end, as in the Spindle- Shaped F usus or
w ith the last turn very large , as in the ear-shaped Ha liotis ;
or the co i l may have a flattened base, as in the top
shaped Trochus . When the Shelly cone is not spirally
co i led, it is often tubu la r, as in the tooth — shaped D enta
lium ; or flattened ou t, as in the sh ield- shaped S cutus ;
simply conical , a s in the L impet or slipper-shaped, as in
Crypta and Ca tillus . The co ils are genera lly right-handed ,bu t somet imes they are sinistra l , as in Clausilia . T he
marine spira l Gasteropods, which breathe by gills, u sua lly
have the mou th o f the shell c losed when at rest by a
horny, or ca lcareous opercu lum ; the a ir-brea thing families
are either provided w i th a similar means o f defence , or are
entirely destitute of this appendage .
