PREFACE.
—_——
In offering to the public a work on so interesting a subject as the science of
Concuotocy, my desire is to assist a discerning community in the study of
nature in all her variety of marine and earthborn shells. To attain this object,
it has been my study to compile a work, in as ample a form as possible, from
the best, most copious and approved translations at present extant, of Linnxus
and Lamarck, and from the more modern productions of Woop, Suaw, Ditiwyn,
Mawe, &c., as well as remarks from ArisToTLe and Puiny, of ancient date,
in order to arrange the system adopted.
To enumerate the many kind acts of friendship in the assistance rendered to
this work, is a grateful task. Should I forget to name any such individual, I
trust it will be imputed to the treachery of my memory, rather than to the want
of a sense of the obligation which I feel.
George William Pratt, Esq. I am bound in duty to acknowledge as my patron.
From the Rey. Francis William Pitt Greenwood, I have received much infor-
mation, and am greatly indebted. To Dr. Storer, Dr. Gould, Elijah Clark, Esq.
and the ladies Barnard, Smith and Coffin, my thanks are due. To a young
friend, whose modesty forbids the mention of his name, I am greatly obliged, as
well as to Mr. James J. Jarvis, a young man of great talents, and one who bids
fair to be a shining character, and an ornament to society and his country.
But I must not forget Seth Bass, Esq. M. D. from whose urbanity, kindness
and attention, I have profited much. The use of his private library, papers and
information, has been, in a great measure, my sheet anchor. It is entirely to
him I am indebted for the list of Unio. This obligation I feel sensibly.
The Linnzan System, being by far the least complex, I have considered in
the First Part; being only thirty-six genera, with their divisions and families.
The Second Part is entirely confined to the Lamarchian.
To study nature in every science is beautiful, but in this it is both gratifying,
edifving and sublime. If it gives pleasure and leads the mind to higher objects,
my end is answered.
Joun Warren.

INTRODUCTION
TO
CONCHOLOGY.
Each moss,
Each shell, each crawling insect holds a rank,
Important in the plan of HIM, who framed
This scale of beings.
Stillingfleet.
Shes form a link in the great chain of nature, worthy the
researches of men of science ; and when we consider the wonderful diversity
of singular and beautiful forms, which they present to our notice, they cannot
fail to invite the attention of the most common observer. CONCHOLOGY,
indeed is a study peculiarly adapted to recreate the senses, and insensibly to
lead us to the contemplation of the glory and order of the great God, in
creation.
This science has, in a greater or less degree, attracted the attention of curi-
ous and contemplative minds in all ages: the multiform beauties of Shells,
did not escape the observation of Philosophers, in the most brilliant eras of
learning, as appears obvious, from the writings of Aristotle, Pliny, and of
Aslian, and we may also add of AXthenaus, and of Cicero. ‘‘ What can be
more gratifying,’’ (says Pliny) ‘‘ than to view nature in all her irregularities,
and sporting in her variety of shells ; such a difference of color do they ex-
a
hibit ; such a difference of figure ; flat, concave, long, lunated, drawn round
ina circle, the orbit cut in two ; some with a rising on the back, some smooth,
some wrinkled, toothed, streaked, the point variously intorted, the mouth
pointed like a dagger, folded back, bent inward ; all these variations, and
many more, furnish at once novelty, elegance, and speculation.””» CONCHO-
LOGY was neglected in the darker era which succeeded to that of classic
effulgence ; but in after ages as the mists of Gothic ignorance, which had
so long overhung the Western World, dispersed, and the light of science, like
the morning twilight, dawned upon the horizon of the human mind, CONCHO-
LOGY revived, was countenanced, encouraged, and flourished. And if in
later times, it resigned a preference or precedence to other sciences, in
conformity to the example of the great Linneus, who was, perhaps, less
favorably inclined towards the study of Shells, than any other department of
nature, it is pleasing to add, that since his time, this subject has been most
assiduously cultivated, and that by writers no less eminently qualified to exalt
its character than to give stability to the science itself.
Beauty of Shells.
The colors of Shells are often so intensely vivid, so finely disposed and
so fancifully variegated, that, as objects of beauty, they rival any of the es-_
teemed production of the vegetable kingdom. In their forms they likewise
exhibit an infinite variety. Whilst some consist merely of a hollow cup, or a
single tube, others exhibit the most graceful convolutions, and appear in the
~ form of cones, and spires, and turbans ; in another division shaped like a box,
all the varieties of hinge are exhibited, from that of a simple connexion, by a
ligament, to the most complicated articulation. The forms are indeed so
various, and many of them so elegant, that a celebrated French Concholo-
gist warmly recommends them to the attentive study of the Architect. In
this country, however, no such recommendation is necessary, as many of our
beautiful ornaments of Stucco, particularly for chimney-pieces, device are
copied from the Univalve Testacea, and are greatly admired.
But Shells, even with all their beauty, and elegance would never have ac-
quired so much importance in the eyes of mankind, had their forms been so
difficult to preserve, as the external coverings of the higher classes of ani-
5
mals. It is both a tedious, and a difficult operation to preserve a Quad-
ruped, a Bird, or a Fish, as a specimen for the cabinet ; and even when
the task is completed, it is but of temporary duration. A slow but certain
process of dissolution is going on, which, though invisible for a time to the
owner, gradually destroys the finest collection of these objects. The very
changes of the atmosphere, combined with the attacks of insects, accelerate
the destructive process. But with Shells the case is very different, composed
of particles, already in natural combination, they do not contain within them-
selves the seeds of dissolution ; so that for ages they remain the same.
Besides all that is necessary in general to prepare a Shell for the cabinet,
is merely to remove the animal, and when the Shell is covered with foreign
matter, to wash it away, with a brush, in soap and water, and it is frequently
necessary to steep the shell for some time in fresh water, to extract all the
salt water that may adhere to it. After being properly dried, it is fit for the
shelf of the cabinet, and stands in no need of anxious superintendence.
To some, the examination of this department of science has appeared
useless, and unworthy of occupying the time, and talents of an informed mind :
reasoning with persons of this description is seldom attended with any good
effect ; ignorant of the advantages which have resulted to mankind from an
intimate acquaintance with natural objects, which an all-perfect being, has
created, they know not the pleasure which may be thus yielded to man, who
was sent into this world in order to examine, admire and adore.
ALMIGHTY BEING!
Cause and support of all things, can we view
These objects of our wonder—can we feel
These fine sensations, and not think of THEE 2
If we attend to the contour or shape of Shells, we find elegance and sim-
plicity, richness and variety of their colors, the singularity of their forms in
many, and the comparative facility with which they may be collected and
arranged, we cannot be surprised that they have now attained a conspicuous
place in public collections, and have attracted the notice of the curious
observer.
Rumphius is said to have given a thousand pounds, for one of the first dis-
covered specimens of the Venus Dione.
The Conus Cedo Nulli, so very rarely offered for sale, fine, was sold for
three hundred guineas ; the Turbo Scalaris, if large and perfect, has been
6
estimated worth one hundred guineas. The Cypre Aurantium or Orange
Cowry, perfect, has been sold for fifty guineas, and the Voluta Aulica, forty
pounds ; this with the Conus Gloria Maris, at fifty four pounds, at this period
keep their prices, but all the others noticed are considerably (under the influ-
ence of several coming to market,) reduced in their value.
It has been estimated that a complete collection of British Shells (alone) is
worth its weight in pure silver.
But to view Shells merely as objects of beauty, without attending to the
animals of which they form a part, would be to overlook by far the most im-
portant branch of the science ; and like the Florist to take notice of color,
and shape, and neglect to attend to those functions, which, while they excite
our astonishment, exhibit marks of design. The examination of the inhabit-
ants, enlarges our knowledge of the laws of animal life, and teaches us that
each Shell, however insignificant it may seem to be, possesses faculties,
suited to the supply of its wants, and to the situation it is destined to occupy.
As objects of Utility to man, Shells are eminently worthy of our notice.
To the savage, Shellsfurnish some of his most important instruments. They
often answer all the purposes of a knife, and are extensively employed, as a
substitute for iron ; with pieces of their most solid bivalves, he points his ar-
rows and forms his fish-hooks. The blue and white bells of the Indians of
this country, are used as tokens or symbals of peace and amity, in opposition
to the war hatchet, and by which the fate of nations has been so often decided
are made of the Venus Mercenaria ; and the gorget of the chieftains war-dress,
is formed of the Pearl bearing muscle (Mytilus Margaratiferus.) The mili-
tary horn of many African tribes, is the Murex Tritonis ; the rare variety
of which, with the volutions reversed, is held sacred, and is used only by
their High Priests. The highest order of dignity, among the Friendly Is-
lands is the permission to wear the Cyprea Aurantium, or Orange Cowry.
Lister relates that the inhabitants of Nicaragua fasten the Ostrea Virginica
to a handle of wood, and use it as a spade to dig up the ground. Even
when further advanced in civilization the canaliculated univalves sometimes
constitute the rustic lamp, while the larger scallops are employed by the dairy
maid to skim her milk, and slice her butter. From the mother of pearl shell,
many useful and ornamental articles are fabricated, and calcined shells were
formerly esteemed by Physicians as absorbents, and are still regarded by the
farmer, as furnishing a valuable manure. The greater part of the lime used in
7
this country, for agriculture and architectural purposes, is made of calcined
shells. The public street of Christianstadt, and Santa Cruz, are paved
with the Strombus Gigas, or great screw shell ; and the town of Concliylion
is entirely built of marine shells. The Cyprea Moneta or money cowry, form
the current coin of many nations of India and Africa, and the covering or coat
of an inconsiderable worm, stands at this day, as the medium of barter for the
liberty of man, a certain weight of them being given in exchange for a slave.
The scholar needs not the reminiscence that the suffrages of the ancient
Atheneans were delivered in, marked upon a shell.
He whom ungrateful Athens could expel,
At all times just but when he signed the Shell.
Pope.
The record of which is still commemorated on the derivation of our terms
Testament and Attestation. The word testado or shell is used, for a musi-
cal instrument in poetry, the first lyre being said to have been made by strain-
ing strings over the shell of a Tortoise :
Less than a God they thought there could not dwell
Within the hollow of that shell,
That spoke so sweetly. Dryden.
The Hermes or Mercury of the Egyptians surnamed Trismagistus, or thrice
illustrious, is reported by Apollodorus to have been the inventor of music,
under the following circumstances. The Nile having overflowed its banks, and
inundated the whole country of Egypt, on its return to its customary bounds,
left on the shores various dead animals, and among the rest a Tortoise, the
flesh of which, being dried, and wasted by the sun, nothing remained within
the shell, but nerves and cartilages, and these being tightened and constricted
by the drying heat, became sonorous. Mercury, walking along the banks of
the river, happened to strike his foot against this shell, and was so pleased with
the sound produced, that the idea of the lyre suggested itself to his imagination.
The first instrument he constructed was in the form of a Tortoise, and was
strung with the sinews of dead animals. There is something beautiful in this
allegory which leads us into a conception of the energetic powers of the
human mind, in the early ages of the world, thus directed to a discovery of
the capabilities of nature, by the finger of Omnipotence in the form of accident.
8
This fanciful mode of accounting for the origin of music is thus curiously
alluded to in Brewer’s Lingue.
The lute was first devised
Tn imitation of a Tortoise back,
Whose sinews, parched by Apollo’s beams,
Echoed about the concave of the shell;
And seeing the shortest and smallest gave shrillest sound
They found out frets, where sweet diversity,
Well touched by the skilful learned fingers,
Roused so strange a multitude of chords.
And the opinion many do confirm
Because Testado signifies a Lute.
Shells as one of the agents of decomposition, and gradual dissolution, will
afford material assistance to the geologist, when he examines into their rapid
and astonishing powers of perforating and disuniting rocks of calcarious sand-
stone, limestone, marble, and even the hardest masses of granite and porphyry,
wherever they come in contact with the ocean, and by a comparative exami-
nation of the different stratifications of marine testaceous depositions he may
eventually be led to some important conclusions as to the probable elevation
of the waters of the general Deluge.
From what has been adduced, it must now be obvious to the reader that
shells are of considerable importance in the arts of life; but the animals con-
tained in these Shells are of far greater value. As articles of food shell-fish
are extensively employed by the poor, and even hold a conspicuous place
at the tables of the rich. In many places, they in a great measure support
the children of a maritime population, and in the Western and Northern Is-
lands of Scotland, have in years of scarcity prevented the death of thousands,
besides affording employment to as many who are constantly engaged in search-
ing for shell-fish, and bringing them to market. Independently of the food
thus obtained from Testaceous bodies, they afford that treasure of a Shell
the Pearl, one of the most beautiful and costly ornaments, equally prized by
the savage and the citizen; And supply us also with a dye—the famous
Tyrian purple of antiquity, which constituted an attribute of imperial gran-
deur. ‘Thus we perceive that the study of Conchology rises in importance as
we discover its usefulness.
Conchology or Testaceology, as it is now sometimes called, comprises the
Molusca Testacea, or self-bodied animals furnished with shells, being the third
9
order of the fourth class of Vermes or Worms. In the Linnzan system of
Zoology, Shells are divided into
Multivalves, Bivalves, and Univalves.
A Multivalve shell may be exemplified by any species of Lepas or Barna-
cle, in which the shelly covering of the animal is formed of several pieces or
divisions. The Bivalve, by the muscle in which, as every one knows, the
shell is composed of two pieces or valves ; and lastly, the Univalve shell by
the common snail, for the shell is simple and undivided. The shell animals
are produced from eggs, which in some animals are gelatinous or gluey, and
in others covered with a hard or calcareous shell, and the young animal
emerges from the egg with its shell upon the back. The most familiar and
convincing proof of this may be obtained by observing the evolution or hatch-
ing of the eggs of the common garden snail, as well as several of the water
snails, which deposit eggs so transparent, that the motions of the young, with
the shell on its back, may be very distinctly seen several days before the
period of hatching.
All the shell animals are of such a constitution as perpetually to secrete or
exude from their bodies a viscid moisture ; and it is with this, managed ac-
cording to the exigencies of the animal, that the shell is through life increased
in dimensions, and repaired when accidentally broken in any particular part.
The growth of shells proceeds from the edges of the mouth, or opening ; and
thus the spires or turns of the Univalve shells are gradually increased in
number and size, till the animal has arrived at its full growth.
Linneus has divided shells into thirty-six genera; and the total amount of
species hitherto described is 2445, exclusive of varieties, of which 550 are to
be found in and around the British Isles. There are many species, no doubt,
that have not yet made their way into the catalogues of Conchological writers;
and we have reason to suppose that hundreds or thousands may be still un-
known.

MULTIVALVES.
No. 1. CHITON.
Coat of Mail Shell. Inhabitant a Donaz.
Part in their pearly shells, at ease attend
Moist nutriment; or, under rocks, their food
In jointed armor watch.
Accorpine to the Linnean system, the Chiton is the first shell and animal
noticed. ‘The Chitons are natives of the ocean, and are generally found
adhering to rocks or stones that are overflowed by the tide, but it possesses
the power of removing from its station. The Chiton much resembles the
marine wood-house, and has often been mistaken for it, and possesses the
same power of rolling itself into a perfect ball.
The body of the Donax is creeping, oblong, and flat beneath. The mouth
is placed below, on the fore-part; vent behind, on the back, and surrounded
by a fringe; feelers two or four, situated on the upper part of the body in front,
and retractile within the proper receptacles.
The shell, consisting of several transverse incumbent valves, is disposed in a
longitudinal series down the back. We have known very little of this genus
until the few last years. So lately as the period in which the 10th edition of
the Systema Natura appeared, only four of its species were known; at least, no
great number are described by Linneus. To the valuable work of Chem-
nitz, we are indebted for the addition of thirteen other species; to Schocter
and others, for a further variety; so that Mawe states, at this present time,
there are forty of this species known.
The Chiton takes its name from the Greek xitwv (Chiton,) a Coat of Mail.

The Chiton porosus and C. larveformis of this division deserve particular

The valves of the C. porosus are perforated by a small slit, and
the ligament of the C. larveformis (which in other respects in the species
merely surrounds the margin) almost envelopes the whole shell, and gives it
the appearance of a caterpillar.

Having a spinous margin.
The C. spinosus is at present a very rare shell; its habitat is supposed to
be the Marquesas.
No. 2. LEPAS.
Acorn Shell. Inhabitant a Triton.
Tis genus has been separated into two families, the first (as Lepas anati-
fera) containing the balani or barnacle shells; the second (the Lepas tintin-
abulum) or acorn shell. It is the nature of these shells to adhere in clus-
ters to rocks, shells, the bottom of ships, or floating pieces of wood, where
they are sometimes seen in countless numbers. Colonel Montague relates,
that he observed a piece of fir timber about twenty feet long, which was drift-
ed on the coast of Devonshire, England, and which, from end to end, was
completely covered with them. They appear particularly attached to wood,
where they cluster together of all sizes, the smaller adhering by short pedi-
cles to the larger ones.
The animals contained in these shells, as well as in those of the other spe-
cies, have an oblong body, each 24 claws or tentacula, all joined in pairs near
the bottom, and inserted in one common base ; the twelve longest stand some-
what erect and arched, and arise from the back part of the animal. They
appear like so many curled feathers, clear, horny, and articulated. Every
joint is furnished with two rows of hairs on the concave side : they are of use
in catching prey, and the animals are continually employed in extending and
contracting them for this purpose. The twelve smallest are placed six on
each side: in front of these, they are more pliable, and more thickly set
with hairs than the others, and seem to perform the office of hands. The
mouth, formed not unlike a contracted purse, is placed in front, between
the smaller claws, and within its folds are situated six or eight horny lamine
or erect teeth. Under this lie the stomach and intestines, and the tendons
by which the animal adheres to the shell.
Only twelve species are described in the Grewlinnean system: the genus
takes its name from the Greek A¢sras, the rock to which the shell adheres.
The barnacle shells have long been known, in consequence of a fabulous
notion formerly prevalent, especially in Great Britain and Scotland, even
among those who ought not to have been so deceived,—that from them was bred
a species of goose, common on the British coast, called the Barnacle Goose.
13
Of the numerous writers, who have mentioned and credited these circumstan-
ces, I shall notice three only, all of whom speak confidently and positively on
the subject. The first is Maier, who writes a treatise expressly on this bird:
he says, that it certainly originates from shells; and, what is still more wonder-
ful, says, ‘“‘ he opened a hundred of the goose-bearing shells in the Orkneys,
and found in all of them the rudiments of the bird completely formed.”
Gerard is another writer on this subject. His account of this miraculous
transformation, I here insert in his own words, which have been often quoted:
‘¢ What our eyes have seen, and our hands have touched, we shall declare.
There is a small island im Lancashire (England,) called the Pile of Foulders,
wherein are found broken pieces of old and bruised ships; some thereof have
been cast thither by shipwrecks: also, the trunks and bodies, with the branch-
es of old and rotting trees, cast up there likewise, whereon is formed a certain
spume or froth, that in time breedeth unto certain shells, in shape like
those of the muscle, but sharper pointed and of a whitish color; and the end
whereof is fastened unto the inside of the shell, even as the fish of oysters and
muscles are, and the other end is made fast unto the belly of a rude mass or
lump, which in time cometh into the shape and form of a bird: when it is per-
fectly formed, the shell gapeth open, and the first thing that appeareth is the
aforesaid lace or string; next cometh the legs of the bird, hanging out; and as
it groweth greater it openeth the shell by degrees, till at length it has all come
forth, and hangeth only by the bill: in a short space after, it cometh to maturi-
ty and falleth into the sea, where it gathereth feathers, and groweth to a fowl
bigger than a mallard, and lesser than a goose, having black legs, and bill or
beak, and feathers black and white, spotted in such a manner as our magpie,
called in some places pie-annes, which the people of Lancashire call by no oth-
er name than tree goose; which place aforesaid, and all those places adjoin-
ing, do so much abound therewith, that one of the best is bought for three
pence. For the truth hereof if any doubt, may it please them to repair to me,
and I will satisfy them by the testimonies of good witnesses.”’
The last I shall mention is Sir Robert Murray’s account of the barnacle,
inserted in the Philosophical Transactions. ‘‘In the Western Islands of
Scotland, the west ocean throws upon their shores great quantities of very
large weather-beaten timber: the most ordinary trees are wood and ash. Be-
ing in the Island of East, I saw lying upon the shore a cut of a large fir-tree,
14
about two feet and a half in diameter and nine or ten feet long, which had lain so
long out of the water that it was very dry, and most of the shells that had
covered it were worn or rubbed off, only the parts that Jay next to the ground:
there still hung multitudes of little shells, they were of the color and con-
sistence of muscle shells. This barnacle shell is thin about the edges, and
about half as thick as broad. Every one of the shells hath some cross seams
or sutures, which, as I remember, divide it into five parts: these parts are fast-
ened one to another, with such a film as muscle shells have. These shells
are hung at the tree by a neck longer than the shell, of a kind of filmy sub-
stance round and hollow, and creased not unlike the windpipe of a chicken,
spreading out broadest where it is fastened to the tree, from which it seems to
draw and convey the matter which serves for the growth and vegetation of
the shell and little bird within it. In every shell that I opened I found a
perfect sea-fowl, the little bill like that of a goose; the eyes marked; the head,
neck, breast, wing, tail, and feet, formed; the feathers everywhere per-
fectly shaped and blackish colored, and the feet like those of other water-
fowl, to my best remembrance.”’
Few subjects seems to have been more circumstantially related, or to rest
on better evidence, than the above; so natural to man is credulity, which
passes all bounds where prodigy of an event takes firm hold of the imagination,
and lays the understanding asleep. Such are the wild chimeras that have been
retailed concerning the origin of barnacles; and as these fables once had great
celebrity, I have been induced to relate them, to show how contagious the
errors of science are, and how prone men are to the fascinations of the mar-
vellous. Barnacle geese are not uncommon on many of the northern and west-
ern coasts of Britain in winter; but they are scarce in the south, and are seldom
seen except in inclement seasons. They leave in February, and retire north-
ward to breed.

No. 3. PHOLAS.
Peirce Stone. Inhabitant an Ascidia.
THE animals of this tribe perforate clay, spongy stones and wood, very young;
and as they increase in size they enlarge their habitation, and thus become
imprisoned. Before these animals attempt to penetrate stones, they soften them
by discharging a quantity of phosphorescent fluid, which decomposes or cor-
rodes the substance, as effectually as any chemical solvent, and prepares it for
the reception of the shells, which they are enabled to insert in the manner of
a screw, the worm being spiral and toothed; the animal then begins to make an
entrance with the larger end of the shells, and thus all possibility of return is
cut off. They are always found below high-water mark, and a mass of rock may
sometimes be seen wholly perforated by them. They have two orifices or
openings capable of elongation, in the manner of a proboscis: one of them is
supposed to be the mouth, and has the faculty of spouting water: most of them
contain a phosphorescent liquor of great brilliancy in the dark, which also
illuminates whatever it touches or happens to fall upon.
The Pholas is so called from the Greek: Qwads, to lurk in cavities, or
seek a hiding place.
The Pholas dactylus affords the character of nearly the whole tribe. The
very extraordinary powers possessed by these animals of penetrating into solid
bodies, when compared with their apparent imbecility, have justly excited
the astonishment of Philosophers and Naturalists of all ages. When divested
of their shell, they are roundish and soft, with no instrument that in the least
seems fitted for boring into stones, which they are known to do, or even for
penetrating the softest substance. They are indeed furnished with two teeth;
but they are placed in such a situation as to be incapable of touching the hol-
low surface of their stony dwellings. They have also two corners to their
shells, which open or shut at either end; but these are totally unserviceable to
them as miners. The instrument with which they perform all their operations,
and by means of which they bury themselves in the hardest rocks, is only a
broad, fleshy substance, somewhat resembling a tongue. With this soft, yield-
ing instrument, while yet young and small, they work their way into the sub-
re
stance of the stone and enlarge their apartment, as their increasing size renders
it necessary. The seeming unfitness, however, of these animals for penetrating
into rocks, and there forming an habitation, has induced many Philosophers
to suppose that they entered the rock while it was yet in a soft state, and from
the petrifying quality of the water that the whole rock afterwards became hard-
ened round them by degrees. This opinion has been confuted ina very satis-
factory manner by Dr. Bohads, who observed that many of the pillars of the
Temple of Serapis, at Puteoli were penetrated by these animals ; whence he
justly concludes, that the Pholades must have pierced them after they were
erected ; for no workman would have labored a pillar into form, if it had been
honey-combed by worms in the quarry. . In short, there canbe no doubt, but
that the pillars were perfectly sound when erected, and that these animals attack-
edthem during the time in which they continued buried under water after the
Earthquake that swallowed up the city. From hence it appears, that in all
nature there is not a greater instance of perseverance and patience than that
which this animal is seen to exhibit. Furnished with the bluntest and softest
auger, by slow successive applications it effects what other animals are incapa-
ble of performing by force, penetrating the hardest bodies with only its tongue.
When (as I have before stated) while yet very small, it has effected an en-
trance, and buried its body in the stone, it there continues for life at its ease,
the sea water that enters at the little aperture supplying the animal with Juxuri-
ous plenty. Upon this seemingly thin diet it by degrees grows larger and
larger, and soon finds itself under the necessity of increasing the dimensions of
its habitation and its shell.
The motion of the Pholas is slow almost beyond conception: its progress
keeps pace with its growth of body ; and in proportion as it becomes larger, it
makes its way further into the rock; when it penetrated to a certain depth, it
turns from its former direction and hollows downward, till at last, when its hab-
itation is completed, the whole apartments resemble the bowl of a tobacco-
pipe, the hole in the shank being that by which the animal entered. Thus
immured, the Pholas lives in darkness, indolence and plenty: it never removes
from the narrow mansion into which it has penetrated, and seems _ perfectly
content with being inclosed in its own sepulchre. These animals are found
in the greatest quantity at Ancona in Italy, also along the shores of Normandy
and Poictou in France, and upon some of the coasts of Scotland. In general,
they are considered as a great delicacy at the tables of the luxurious.

BIVALVES.
No. 4. MYA.
Gaper. Inhabitant an Ascidia.
The ocean rolling, and the shelly shore;
Beautiful objects.
Suext bivalve, generally gaping at one end, hinge has a solid thick patulous
tooth, but seldom two, and not inserted in the opposite valve. ‘The name or
term Mya is also derived from the Greek wvas, which is from wiw, to com-
press. It was formerly applied to the mytilus.
The greater part of these animals are inhabitants of the ocean, but some
of them are found in fresh water. They perforate the sand or mud at the bot-
tom. Many of the species are caught for food, and others for the pearl, which
are formed within their shells ; some few of the species perforate and live in
limestone, in the same manner as the Pholades.
The pearl bearing Mya, (Margaritifera) is found chiefly in the large rivers
of northern latitudes. ‘The British islands, especially Ireland, have been
considered famous for their fisheries of the Mya, and a few pearls of great
value have at times been obtained from these sources; but the quality of
British specimens is not held in the highest estimation. Some fine pearls,
however, were procured from the Shannon, in the year 1821. The river
Irt, in Cumberland, the Canway, in Wales, and the Fay, in Scotland, were
once noted for their pearl fisheries. Suetonius reports, that Cesar was in-
duced to undertake his British expedition for the sake of the pearls, and,
according to Pliny and Tacitus, he brought home a buckler made with
20
British pearl, which he dedicated to, and hung up in the temple of .the idol
Venus Genetrix.
Several species of gapers are used as food, both in Britain and on the
continent, as the Mya Arenaria, known to the fishermen about Southamp-
ton, by the whimsical name of Old Maids. hese shells reside in the
mud, or shingle on the shore, laying a few inches below the surface. In
some parts of England and-Ireland they are much used; but, though common
in Scotland, they are never sought after. Another species, (the Mya Trunca-
ta) is also very common on the coast. It prefers a hard, gravelly bottom,
in which it lodges at low-water mark. The inhabitants of the Northern
Islands call it Smuslin, and employ it, when boiled, as a supper dish. It is
by no means unpalatable.
This genus has several divisions.
DIVISION I. JHinge with one or two rounded teeth not inserted in the
opposite valve.

No. 5. SOLEN.
Razor Shell. Inhabitant an Ascidia.
Shell oblong, gaping at both ends, tooth of the hinge subulate reflex, gen-
arally donble, not inserted, lateral margin obsolete: in the Solen radiatus, there
is an internal rib, extending from the hinge to the margin of the cavity, in a
longitudinal direction. The great disproportion in the breadth of the Solen
is a remarkable character, and serves to distinguish them from every other
genus.
Solen is also derived from the Greek word owdnv, signifying a tube. The
French designate the Solens, Manches de Couteaux, in allusion to their
shape.
Many of the bivalved shell fishes have the powers of progressive or retro-
grade motion, by an instrument that has some resemblance to a leg or foot, and
called the tongue. But these animals can at pleasure make this assume almost
any form which their exigencies require. They are incapable of progressive
motion on the surface, but they dig a hole or cell in the sand, sometimes two
feet in depth, in which they ascend, or descend, at pleasure. The instru-
ment, or tongue, by which their motions are performed, is fleshy, cylindrical,
and situated near the centre of their body. When necessary, the animals
can make the termination of the tongue assume the form of a ball. The
razor-fish, when laying on the surface of the sand, and about to sink into it,
extends its tongue from the inferior end of the shell, and makes the extremity
of it take the form of a shovel, sharp on each side, and terminating in a point.
With this instrument the animal cuts a hole inthe sand. After the hole is
made, it advances the tongue still further into the sand, makes it assume the
form of a hook, and with this hook, as a fulcrum, it obliges the shell to de-
scend into the hole. In this manner the animal operates, until the shell
totally disappears. When it chooses to regain the surface, it forms the
termination of the tongue into the shape of a ball, and makes an effort to
extend the whole tongue; but the ball prevents any further descent, and the
muscular effort necessarily pushes the shell upward, until it reaches the
surface. It is amazing with what dexterity and quickness these seemingly
awkward motions are performed.
Two kinds of razor-fish, (Solen Siliqua, and Ensis) are in many places of
Great Britain used as food. In Scotland, they are indiscriminately termed
23
Spout-fish. They are found upon most sandy shores, buried about a foot or
two below the surface, and near to low-water mark. Their place is known
by a small hole in the sand. As it is rather a laborious operation to dig them
- out, Bosc informs us that the fishermen in France throw a small pinch of
salt into their holes, which always remain open by the action of the respitary
organs; that they speedily rise to the surface, and are thrown out by an iron
instrument made for the purpose. The fishermen believe it is the salt they
wish to avoid; but it is conjectured, with greater probability, that the presence
of the salt water, which is thus formed by the solution of the salt, makes the
animal suppose that its hole is again covered with the tide. ‘This shell
fish was esteemed by the ancients as a great delicacy. When boiled or
fried, it is certainly a palatable morsel. If kept afew days, it forms an
excellent bait for haddock or cod, and may be employed for that purpose in
a fresh state.
Most species of the Solens are covered with a thin cuticle or epidermis,
which renders the colors beneath more or less obscure.

No. 6. TELLINA.
Bent Wedge. Inhabitant a Tethys.
The Tellin are usually found buried in sand or gravel, on the sea shores,
and some kinds in rivers or ditches. Among all the genera of bivalves, there
are none except the Venus, which can vie with the Telline, in elegance of
form, brilliancy of color, or delicacy of structure.
The body is detached, oblong, fleshy, without peduncles, mouth furnished
with a terminal, cylindrical proboscis, under an expanded membrane or lip,
apertures, two on the left side of the neck, shell bivalve, generally sloping on
one side, in the fore part of one valve, a convex of the other, a concave
fold, hinge with usually three teeth, the lateral ones smooth in one shell.
The Telline, as now defined, consists of those orbicular bivalve shells or
transverse, having a regular fold or wrinkle at the anterior end of the shell,
with one or two teeth pointed to the beak, and remote lateral teeth.
It is difficult to beginners in the science of Conchology to discriminate
between the genera Telline and Venus. The difference will best be learnt
by observing principally the inclination of the beaks: if they at all tend to-
wards the ligament, the shell will belong to the genus Tellina; also, if any
remote, lateral teeth be discernible, if the anterior slope be compressed into
an acute, wedge-shaped form, or if it be crooked.
The word Teddy from which Tellina is derived, signifies to arrive quickly
at maturity. Of this genus, there are 81 species, and three divisions.

No. 7. CARDIUM.
A Cockle. Inhabitant a Tethys.
Shell bivalve, nearly equilateral. Equivalves generally convex, longitudi-
nally ribbed, striated or sulcated, with the margin toothed. Hinge with two
alternate teeth in the middle, near the beak, in most incurved, lateral teeth
remote, and inserted or locking into the opposite. Forty-nine species of
this genus were described in the last edition of the Systema Nature.
The genus Cardium is somewhat cordiform in its shape, with the valves
denticulated or folded at the margin, beaks turned inward, hinge with
the two oblique teeth in each valve near the back, locking into each
other ; the ribs and furrows of the two valves are so disposed as to alternate
at the margin, and to lock accurately and firmly into each other.
The word cardium is derived from xagdia, signifying heartlike, from the
cordate appearance of the genus.
Upon the sandy shores of all the known seas, some of the species of Cockle
are to be observed. Most are found immersed in the sand, at the depth of
afew inches. Their size varies from five or six inches to half an inch in
diameter. The common Cockle is well known. All the locomotive powers
of the Cockle are concentrated in the triangular yellow foot, which is so con-
spicuous when we open the shells. This foot is not only capable of great
inflexion, but also of seizing with its point the glutinous matter which pro-
ceeds from it, drawing this into threads, and thereby, in some measure, se-
curing the animals within the sand. Few shell fish are more common in inlets
and bays, and near the mouths of rivers, than these. In such situations they
are usually found, the place of each being marked by a small circular
depressed spot. When they open their shells, the entrance into these is
protected by a soft membrane, which entirely closes up the front, except in
two places, at each of which there is a small yellow and fringed tube, by
means of which it is that the animals receive and eject the water which con-
veys to their body the nutriment necessary for their support. Women and
children easily dig up this shell fish. Cockles in England and Wales are
sold by measure, and eat either raw, boiled, or pickled. They are deserv-
21
edly esteemed a delicious and wholesome food in Great Britain; in France
little regarded.

No. 8. MACTRA.
Kneading-trough. Inhabitant a Tethys.
Shell bivalve, inequilateral, valves equal, middle tooth of the hinge compli-
cated with a small hollow on each side, and lateral remote teeth inserted into
each other. Twenty-seven of this species are described by Grewelin (Maxrea
signifies a kneading trough; but the resemblance to this article in any one of
the Mactre is very slight,) and the number of species now known amounts to
forty-two.
These are generally found at the mouths of rivers, immediately beneath
the surface of the sand, or among substances that have been thrown up, and
left by the sea. The prevailing color is a bluish or yellowish white. One
kind is used as food by the common people at Dartmouth, Devonshire, Eng-
land.
The genus Mactra possesses little beauty or variety, and a similarity of
coloring and form pervades the whole.

No. 9. DONAX.
Wedge Shell. Inhabitant a Tethys.
The shell bivalve, with the margin generally crenulated, the anterior end
very obtuse, hinge with two teeth, a solitary one somewhat remote, (the lat-
ter rarely double, triple on none.) According to Grewelin, this genus has
19 species. Adva¥ signifies an arrow: on account of the rapidity of its
darting through the sand, this term might have been invented.
It is generally found in the sand on the sea shores, when left dry by the
reflux of the tide. The prevailing color is a fine rich purple, but many species
are of a fine rich olive yellow cast. The Donax may probably derive its
name from its shape, which resembles the head of a javelin or arrow; or its
activity on the approach of danger, its arrowy shell being well calculated for
penetrating quickly the yielding substance of the shore.
The Donax presents so great a diversity in external character that it has
occasioned the genus to be separated into five divisions.

No. 10. VENUS.
Venus Shell. Inhabitant a Tethys.
Shell bivalve, anterior margin, with incumbent lips, hinge with three teeth,
all which are approximate; the lateral ones divergent at the tip. The Area
and Areola are well defined: the animal differs from the Tethys that inhabits
the Cardium, chiefly in having the foot of the animal when protruded, lamina
formed, instead of hooked, and as a moluscus animal, taking a variety of
forms as the creature moves. Many of the shells of this genus were classed
by writers among the Chamas. Previous to the time of Linneus, the Grew-
linean system describes 145 species, which are divided into five divisions.
The Venus Mercenaria, (called by the Indians qguahaug,) was used by the
Indians of North America to form their wampum. The Venus was so
termed because of the general beauty of the genus, and also because it is
fabled by the ancients that one of them was the chariot of the Sea-born God-
dess, when she came in triumph to the shores of Paphos.
The whole of this elegant shell or genus are oceanic, being either found
in the mud or sand when the tide has receded, or fished up from very deep
water. The Venus shells, of which there are so many species, are remarka-
ble for the brilliancy of their colors and the smoothness of their surfaces, the
interior being often adorned with the most lovely tints. In some species of
the richest purple, especially that called by the inhabitants of Devonshire,

Islands by the name of Cullyack, and there used as a bait.

No. ll. SPONDYLUS.
Artichoke-head Shell. Inhabitant a Tethys.
Shell with unequal valves, hard and rigid hinge, with two recurved teeth,
and a small hollow between. The Linnean Spondyli are few in number,
the last edition of the Systema Nature comprehending no more than four
species. Rumphius, Argenville, Seba and Davilla rank the Spondyli as
Oyster; while Lister, Gualteri, Lianeus, Da Costa, &c., consider them as
constituting a distinct genus, under the name of Spondylus: there are now 10
species known. The Spondyli form in their exterior (generally) an interme-
diate family between the Ostrea and Pecten.
Lamarck divides this genus into two, viz. Spondylus and Plicatulus. The
Spondylus has ears, but the Plicatula are without; this constitutes an essential
distinction, but it is not the only one. A striking character is drawn from the
structure and appearance of the back of the lower valve, which projects be-
yond the beak of the upper one, and, in Spondylus, exhibits a plain, triangular,
flat space, divided by a furrow; while, in the genus Plicatula, the beak has
no such characteristic space, or flat surface; and the edges are rumpled or
folded. These new genera are well exemplified in the two Linnean shells,
Spondylus gedaropus, and Spondylus plicatulus.
The name Spondylus is derived from oxovdvAos, signifying an artichoke,
to which plant some small resemblance may be traced.
These shells are found at a considerable depth in the ocean, firmly attach-
ed to rocks, particularly on the coasts of the Mediterranean, where the animal
is eaten as food. The colors of the Spondylus, which are orange, purple, &c.,
are sometimes extremely brilliant.

No. 12. CHAMA.
Clamp Shell. Inhabitant a Tethys.
Chama shell bivalve, rather coarse hinge, with a callous gilbosity obliquely
inserted into an oblique hollow, anterior slope closed. The Chama is so
termed from the gaping observable in two of its species. Large pearls are
sometimes found in the Chama Gigas. One in the possession of the late Sir
Joseph Banks, was valued at between two and three hundred pounds sterling,
the color a dirty white, or yellowish brown, which when polished is as beau-
tifully irriducent as the Opal (Mawe.)
The Chama genus is divided, by the last French writers, into Tridacna, (to
which Chama Gigas belong,) Hyppopus, Cardita, and Isocardia: this last is
founded on the peculiar structure of the Chama Cor of Linnezus, and is thought
an excellent genus.
These, like the last genus, all inhabit the sea, and are found in very deep
water: they arealledible. Some species of the Chama grow to an uncommon
size: the bear-paw clamp shells, usually of a yellowish cast, with pink spots,
are found from one inch to near a foot in length. But this appears as nothing,
when compared with the giant clamp, which from a quarter of an inch will
grow to the enormous size of four and a half feet in breadth, and will weigh
from 100 to 140 pounds. Specimens occur in most public museums of nat-
ural history. In Europe, one individual of this species is recorded (by conch-
ological writers) that weighed 532 pounds; including both shell and animal,
and the latter was so large as to furnish one hundred and twenty men with
food for a meal; and it is recorded, that by the sudden collapsing or snapping
of its valves, it would cut asunder a cable rope, or take off the hand of a man.
This enormous species inhabits the Indian Seas. Those of the largest
size we are acquainted with, are from the seas contiguous to the Island of
Borneo, from whence they are occasionally brought, as objects of curiosity,
-into Europe, and kept as ornaments in gardens. During the early part of the
last century, they were in much request for the ornament or decoration of
fountains, grottos, and reservoirs of water, especially in Italy. This gigantic
shell was perfectly familiar to the poets and sculptors of antiquity. Venus is
39
fabled to have risen in one of them from the bottom of the sea,—an allegory
which has afforded matter for several of the most exquisite compositions of
ancient as well as of modern artists. On antique gems and cameos, Venus,
under various characters, Amphitrite, Doris, and other goddesses and nymphs,
in the train of Oceanus, frequently appear upborne upon the waves. Driden
thus alludes to the pagan allegory:
Albion
Was to Neptune recommended ;
Peace and plenty spread the sails;
Venus, in her shell before him,
From the sands in safety bore him.
This genus contains at present 27 species, which present considerable
diversity of character. Its divisions are two, divided into families.

No. 13. ARCA.
Ark Shell. Inhabitant a Tethys.
Shell bivalve, equivalve, hinge with numerous sharp teeth alternately in-
serted between each other. This genus is divided into two principal families;
those having the margin entire, and those having the margin crenated; and
both families are again subdivided into two sections, the first distinguished by
having beaks recurved, the other inflected. The species described in the
Systema Nature, amount to forty-two.
This genus derives its name from Arca Ark, Noah’s Ark shell, from the
similitudes which most of the species bear, when the valves are closed, to a
boat or hull of a ship. Lister places some of these shells among the multar-
ticulate cockles, and the rest with muscles, under the title of Many-toothed
muscles.
Argenville ranks them as a family of Heart Cockles, and D’Avila and
Gualtieri as a distinct genus; the first, under the title of Arca, the other as
Concha Rhomboidal. These writers were succeeded by Linneus, who
considered these shells as a distinct genus, called Arca. The principal
alteration in the Linnean classification of the genus Arca, proposed by late
writers, is, to reclaim only such shells under the title of Arca, as are uniqui-
lateral with the beaks remote, and have the line of the hinge simple and
straight throughout, with numerous teeth placed parallel to each other, and
fitting between those on the opposite valve, admitting this as the character of
the Arca, and it exactly corresponds with the Arca Noe, and most others.
The little Arca, Nucleus of Linneus, with its analogous species, is excluded.
To comprehend the latter, a new genus is recently established by the French
writers, under the name of Nuculus, or Nucula, the character of which is
remarkably decisive. It is described as a triangular or oblong shell, with the
sides unequal, the hinge consisting of an angulated or broken line, beset
with numerous teeth, which are transverse and parallel, and a single oblique
tooth placed under the beak, and out of the range of parallel teeth above
mentioned. The beaks also, instead of being remote, as in Arca Now, are
placed close together, and turn backwards. The Arca Tortuosa is the rarest
of this genus, and is seldom to be met with.

The Ark shells are to be found in the sea, and on the sands and mud on
the shores of the ocean, generally between low and high water marks. Some
of them are occasionally used as food.

No. 14. OSTREA.
Oyster and Scailop. Inhabitant a Tethys.
Shell bivalve, generally unequal valves, and slightly eared hinge without
teeth, furnished with an ovate hollow, and mostly lateral, transverse furrows;
*¢ Vulva unusque nullus,’’ Linneus; these are divided into three families; valves,
radiated and eared, as in the Pectens; rugged and rough, as in the Oedulis;
hinge with a perpendicular, furrowed line, as in the species Perna, and iso-
nogmon. The Pectens are again subdivided into three sections, viz., those
with the valves inequilateral, and the ears equal; those with the ears unequal,
and having one of them ciliated, with spines within; and those with the
valves gibbous one side: the two other families are not subdivided. The
difference between the Pecten and the Oyster tribe is so obviously impressed
by the hand of Nature, on the respective shells which compose them, that
few writers on this subject have passed over silently the impropriety of
placing them together. As Linneus considers the animals which inhabit the
Scallop and Pecten as the same, and describes them as a Tethys, it may not
be improper to speak more fully on this subject.
The Scallop differs from the Oyster, the animal having the branchie cirra-
ted or fringed, in being furnished with a kind of foot, which it protrudes from
the shell near the article of the hinge, and of throwing abiscus, like the pinna
and the muscles, by which it affixes itself to other bodies.
The Ostra has the branchie simple and not fringed, and is unfurnished,
either with a foot or with byssus, and its powers of motion consist in turning
either the flat or the convex side upwards or downwards; and even to effect
this, the animal takes the advantage of the ebbing or flowing of the tide to as-
sist it. See Lister on.Scallop, P. T. 1st vol.
Lighty species of this genus are at present known.
In Lamarck’s arrangement, the two genera, Huitre Ostrea, and Pieque Pec-
‘en are retained; but four other genera are constituted under the names of Gry-
phus, the Ostrea Gryphus of Linneus, a shell as yet found only in a fossile
state. The most remarkable species of oyster is the Ostrea Malleus, or
Hammer oyster, which resembles a pick-axe, and is (particularly the white
45
variety) very hard to be obtained. Argenville describes the process of the
movements of the Scallop, both in the water and out. He relates that,
‘¢ when left dry by a sudden and violent closing of its valves, assisted by its
foot, it has the power of springing four or five inches at a jerk, repeating this
motion in order to regain its element.’’ In the water he asserts, ‘¢ The
Scallop has the power of rising and sustaining itself near the surface, turning
about in various directions; and, on any alarm, suddenly closing its valves,
sinking to the bottom.”’
OSTREA.
This shell fish is widely distributed, being found, not only in great
abundance in our own seas, but in Europe, Asia, and Africa. But since the
days of the luxurious Romans, the oysters of Great Britain have been held in
the highest estimation : they were noted in the time of Juvenal, who, satyrizing
an Epicure, says,
He whether Circe’s rock his Oysters bore,
Or Lucrine Lake, on distant Richborough’s shore
Knew at first taste.
The luxurious Romans were very fond of this fish, and had their layers
or stews for oysters, as is at present practised. The ancients ate them raw,
and sometimes roasted. They had also a custom of stewing them with mal-
lows and docks, or with fish, and esteemed them very nourishing. Oysters
are found on various parts of the coast of England, from the southern to the
sheltered bays, among the Shetland Islands; but those chiefly celebrated for
them are the Essex and Suffolk coasts : here they are dredged up by means of
nets, with an iron scraper at the mouth, which is dragged by a rope from a boat
over the beds. As soon as taken from their native beds, they are stored in
pits formed for the purpose, furnished with sluices, through which at spring
tides the water is suffered to flow. This water being stagnant, soon becomes
green in warm weather, and in a few days afterwards, the oysters acquire the
same tinge, which renders them of greater value in the market; but they do
not acquire their full quality, and become fit for sale, till the end of six or
eight weeks. The principal breeding time of oysters is in the months of
April and May, when they cast their spawn or spat, as the fishermen call
them, upon rocks, stones, shells, or any other hard substance that happens to
be near the place where they lie, to which the spats immediately adhere.
4G
These, till they obtain their film, or crust, are something like the drop of a
candle, but are of a greenish hue: the substances to which they adhere, of
whatever kind, are called Cultch: from the spawning time, until the end of
July, the oysters are said to be sick; but by the end of August they be-
come perfectly recovered: during these months, they are out of season,
and bad eating.
The Oyster Fisheries, of the principal coasts in England, are regulated by a
Court of Admiralty. In May, the fishermen are allowed to take the oysters,
in order to separate the spawn from the cultch, the latter of which is thrown
in again, for the purpose of preserving the bed for the future. After this
month it is felony to carry away the cultch, and otherwise punishable to take
away the oyster, between whose shells, when closed, a piece of money would
rattle. The reason of the heavy penalty on destroying the cultch is, that when
this is taken away, the oose will increase, and muscles and cockles will breed
on the bed, and destroy the oysters, by gradually occupying all the places on
which the spawn should be cast. ‘There is likewise some penalty for not
treading and killing or throwing on shore any star-fish that happen to be seen.
The prickly star creeps on, with full deceit
To force the Oysters from his full retreat:
When gaping lids their widened void display,
The watchful star thrusts in appointed ray,
Of all its treasures spoils: the rifled case,
And empty shells the sandy hillocks grace.
The common Oyster is contented to remain fixed to his first station, sur-
rounded by an innumerable progeny, continually increasing with wonderful
fecundity. His motions consist only in turning from one side to the other,
which he accomplishes more by sagacity than any natural agility or inherent
strength. He contrives to bolster up one side by a gradual deposition of soft
mud, till he stands nearly upright ; then availing himself of the ebbing or flow-
ing tide, he opens his shell, and is tumbled on by the pressure of the water ;
and as expedition is not his object, this mode may answer well. It has, how-
ever, been observed, that the young fry possess the power of swimming very
swiftly by means of an undulatory motion of the bronchie. The Poet of
nature thus characterizes the Oyster:—
Condemned to dwell
For ever in his native cell;
Ordained to move where others please—
Not for his own content or ease ;
But tossed and buffetted about,
Now in the water, and now out.

No. 15. ANOMIA.
Antique Lamp.
Of this peculiar genus of bivalves there are thirty species, many of which are
extremely rare and valuable. The Anomia differ materially in form ; some
resemble the shape of an oyster, others again are imperforated, and nearly or-
bicular, as the A. Placentia, and some are oblong, as the A. Bifida, &c. Many
species, particularly the A. Caput Serpentis, when seen in profile, resemble
the form of an antique lamp ; and a few, as the A. Psittacea, &c. are very sim-
ilar to the hooked or curved beak of a parrot.
Animal aciliated, strap-shaped body, with bristles or fins affixed to the up-
per valve. Arms two, linear, longer than the body, convenient, projecting,
alternate on the valve, and ciliated each side ; the fringe affixed to each valve.
Shell inequivalve, one flattish the other gibbous at the base, with the beak pro-
duced and generally curved over the hinge; one of the valves often per-
forated near the base hinge, witha linear prominent cicatrix, and a lateral
tooth placed within, but in the flat valve, on the very margin. Two bony
rings for the base of the animal. Many of this genus are only found fossil,
and therefore it is not reasonable to imagine, that we shall ever know the an-
imals by which they were inhabited. It is remarked by Dr. Pulteney, that
the animal of the Anomia is different from any other shell fish, and is not re-
ducible to any of those in a moluscus state hitherto known. Hence probably
the name Linneus imposed upon it, Anomia, (adu:z) quasi irregularis dis
misclis a lege discrepans. The animal of the Anomia Cepa is figured by Mur-
ray inhis ‘¢ Fundamenta Testaceologia,”’ tom. 2, page 23 ; and that of Anomia
Tridentata, by Forskael, in his ‘‘ Icones Animalium,”’ t. 6.40 B. The dissim-
ilarity of the two, renders it highly probable, that in the different shells which
come under the appellations, the inhabiting animal is various. In the Anomia
Tridentata the animal is furnished with two flat, wedge-shaped, trilotated arms,
placed opposite to each other ; these it protrudes out of the shell, when it
moves, and they are the organs by means of which it swims in the sea. Some
other kinds have, instead of arms or the above-mentioned wedge-shaped or-
gans, only a ligament passing through the perforations of the shell, by means
59 |
of which it is firmly fixed to other bodies. Columna is the first writer, who
speaks of shells of this description. He mentions some few of the fossil tribe,
(the only ones known in his time) under the title of ‘‘ Conche variores Ano-
mia.’’ Hence the term was afterwards employed by other writers, and has
since become the universal name for this family of shells. The Anomia
Terebratula is not common, and the Anomia Tridentata very rare: there are
thirty species known, and its divisions are three.

No. 16. MITYLUS.
Muscle. Inhabitant allied to an Ascidia.
For a description of Mitylus see Pholas. Shell bivalve, rough, usually affix-
ed by a beard or byssus of silky filaments, hinge in general without teeth, and,
except in a few species, with a subulate excavated longitudinal line. The Lin-
nean Mityli are by no means inconsiderable in numbers; and as they compre-
hend many shells, very distinct in appearance, some essential particulars
are necessarily distributed into several sections or families, such as parasitici,
hose affixed by classes exemplified in Mitylus Crista Galli, Plani, i. e. flat or
compressed into a flattened form, and slightly eared, as in Mitylus Margatife-
rus or ventri esculi, ventricose as in Mityli Edulis; Lamarck separates them in-
to Mitylus Modiolus and Anodonta. 46 species of the Mitylus are enumerated.
The animal inhabitant of the Mitylus Lithofagus shines like phosphorus in the
dark. This animal is found in the Indian, European and Mediterranean
Seas. The Mitylus Hirundo, or Swallow muscle, inhabits the Asiatic, West
Indian and Mediterranean Seas—is rare and much valued.
Some muscles penetrate into the interior of calcareous rocks, where they
reside out of the reach of danger; others adhere, by their beard, to the exte-
rior of rocks, or stones; and so tenacious is their hold, that in the larger of
their species they cannot be separated without considerable exertion. One
species is gathered from the depths of the sea, on account of the pearls,
which are found within their shells. Of these the Romans were extrava-
gantly fond. ‘It is not enough (says Pliny) to despoil the sea of its riches,
in order to gorge our appetites—we must likewise, both men and women, carry
them about on our hands, in our ears, upon our heads, and on our whole
body.” Persons of every rank purchased them with eagerness : they were
worn on every part of dress; and there is such a difference both in size and
value among pearls, that while such as were large, and of superior lustre,
adorned the wealthy and the great, smaller ones, of inferior quality, gratified
the variety of persons in more humble life. Julius Cesar presented Servilia,
the mother of Brutus, with a pearl, for which he paid £48,457. The famed ear-
rings of Cleopatra were estimated in value £161,458,000.
53
The common, or edible muscle, is found both in the European and Indian
Seas, adhering to rocks by the silky thread which it forms from its body ; but
it grows to a much larger size between the tropics, than in the northern cli-
mates. It abounds on the British shores, being one of the commonest of our
shells. All the muscles have for an instrument of motion, a tongue or foot capable
of considerable elongation, and also of being shortened into the form of a heart.
When the animal feels inclined to change its place, it thrusts its foot out of
the shell, and raises itself on its edge; then, by reaching this to as great a dis-
tance as it will extend, it uses it as a kind of arm, drawing the body up to it ;
and thus it proceeds, until it has found a convenient situation. If the muscle
be inclined to make this his residence, the instrument of his motion is now
put to a very different employment in spinning those silky threads which fix
it firmly to the spot, and, like a ship at anchor, enable it to bear all the agita-
tions of the water. This is accomplished by seizing, with its point, the
gluton supplied by a gland situated under its base, and drawing it out through
the furrow into threads. When the muscle is thus fixed, it lives upon the little
earthy particles, or upon the bodies of such smaller animals as the water
transports to its shell.
The common muscle is generally esteemed a rich, nutritious and wholesome
food ; but to some constitutions it often occasions disorders, the symptoms of
which are great swellings, eruptions, blotches and pimples, shortness of
breath, convulsive motions, and sometimes even deliriums. A remedy that has
been recommended is two spoonfuls of oil, and one of lemon juice, or in
want of this about two of vinegar, shaken well together, and swallowed as
soon as possible after any of the symptoms take place. This unwholesome
quality has been attributed toa small species of crab, that sometimes is found
within the shells: it seems, however, not to have its seat in any thing essential
to the muscle ; for when accidents of this kind have happened, some persons
have been affected, and others have not, who have eat at the same time, and
at least in equal quantity.
The pearl bearing the muscle of the Indian Seas is most abundant and in
greatest perfection, on the coast of the Persian Gulf, and of the island of
Ceylon. In the great fisheries established to supply the eastern market, the
number of fish annually taken up from their beds by divers, whose perilous
trade it is to search for them, is almost incredible. Some of the shells con-
tain one or more pearls; others not any: they are usually detached, but often
adhere to the valves, and are extricated by opening the shell and washing.
54
After the day’s work, the pearls which have dropped out are selected and as-
sorted. The small, or seed pearl, are worth from $15 to $35 per oz.
Those of half a grain weight are sold from 30 to 40 cents each, and those of
one grain from 75 cents to a dollar ; of two grains, from 180 cents to 225.
Those weighing five grains from $7 to $10; and those above 8 grains, if of
fine color and shape, are of arbitrary value.
The finest specimens of extremely rare occurrence have fetched enormous
prices, and have even been considered invaluable, fit only to adorn the regalia
of princes, and contribute to the costly splendor of Asiatic potentates.
These beautiful and unassuming productions, so delicate and varied in their
tints, so elegant in their forms, are more highly estimated, and more generally
used as ornaments in Asia, than in Europe; and consequently the most precious
are returned by the Asiatic merchants.

No. 17. . PINNA.
Nacre, or Sea-wing. Inhabitant a Limaz.
This shell, which forms the connecting link between the bivalve and the
univalve, is so formed as to possess equal claims to either division. The
Pinna are all inhabitants of the ocean, in the sand and mud, on the shore of
sheltered bays: they may be often obtained standing erect, or aflixed by their
beards, to rocks andstones. A bed of these shells was discovered a few years
ago, in Salcomb Bay, near Kingsbridge, Devonshire, in England, by Colonel
Montague. The animals are accounted a very palatable food, but require at
least five or six hours’ stewing.
The Pinna is sub-bivalve, fragile, erect, gaping, and furnished with a bys-
sus or beard, hinge without teeth, the valves uniting into one. This genus is
well defined: the shell of which it consists is wedge-shaped, or somewhat of
a triangular form, widening from a pointed top to a very broad end: the hinge
is inarticulate, the two valves being united in that by a part, and thus forming
what Linneus truly terms it, a sub-bivalve, for it is not strictly two valves being
thus connected. Pinna is derived from the Latin, signifying a pin, &c.
The Pinne are termed by some writers Silk Worms of the Sea, from the
quantity of fine strong byssus which the animals produce: it consists of a
silky filament of a brown color, and which is easily woven into small articles
of dress. There is aconsiderable manufactory of this at Palermo. These
animals are found in smooth water, and in bays. The Mediterranean pro-
duces a considerable number. They are also discovered in the Indian,
American, Atlantic and European Oceans, as well asin the Adriatic or Red
Seas. The byssus is thus produced by the animal:—on any sudden emer-
gency, it darts out an extensive member, and discharges from its lip a drop of
gluton, which, by the drawing back of the same organ, immediately forms a
silky thread, till by a repetition of this simple operation, a thick tuft is at
length completed.
The Earl of Shaftesbury has referred to the production of these industrious
insects, in this elegant manner: ‘‘ How shining, strong and lasting are the
subtle threads spun from their artful mouths! Who besides the All-wise
57
and Omnipotent has taught them to compose, the beautiful shells, in which,
recluse and buried, yet still alive, they form those excellent threads, when
not destroyed
by men, who clothe and adorn themselves, with the labor of
these industrious creatures, and are proud of wearing such inglorious spoils.
The number of this species at present known, are twenty-one, and are in
two divisions

UNIVALVES.
Tue almost imperceptible gradation in this beautiful class of animals ren-
ders the present mode of classification peculiarly interesting, as we are not
under the necessity of separating nearly allied families, as in the classing of
most other natural productions. Most of the shells of this division possess a
regular spiral curve very conspicuous in many of the genera, but gradually be-
coming obsolete.
Learn of the little Nautilus to sail;

No. 18. ARGONAUTA.
Proper Nautilus. Inhabitant a Sepia or Clio.
All the Argonautaare marine shells of exceeding brittle texture, and possess
great elegance of form. ‘The ancients are said to have derived their art of nav-
igation from the animals inhabiting these shells, which raise themselves
to the surface by ejecting the sea-water from their shells, and, on the ap-
proach of danger, draw in their arms, and with them a quantity of water,
which occasions them to sink immediately. By possessing this power, they
are but rarely taken perfect, as the instant they are disturbed they disappear,
and are only accidentally brought up, in the nets of fishermen, or found
left dry on rocks.
59
Two feet they upward raise, and steady keep :
These are the masts and rigging of the ship:
A membrane, stretched between, supplies the sail,
Bends from the masts, and swells before the gale.
The other feet hang paddling on each side,
And serve for oars to row, and helm to guide,
°T is thus they sail, pleased with the wanton game;
The fish, the sailor, and the ship, the same:
But, when the swimmers dread some danger near,
The sportive pleasure yields to stronger fear :
No more they wanton drive before the blasts,
But strike the sails, and bring down all the masts:
The rolling waves their sinking shells o’erflow,
And dash them down again to sands below.
Shell univalve, spiral, involute, membranaceous and unilccular, or consist-
ing of a single shell.— Linneus.
The Sepia body is fleshy, receiving the breast in a sheath, with a tubular
aperture at its base; arms eight, beset with numerous warts or suckers, and
in most species two pedunculated tentacula; head sharp, eyes large, with
mouth resembling a parrot’s beak.
The Clio body oblong, natant generally sheathed, and furnished with two
dilated membranaceous arms, or wing-like processes; tentacula three, besides
two in the mouth.
The Argonauta Argo is the principal species in this genus. It is ascer-
tained that the ancients were acquainted with this species, by many passages
in their writings. That very rare shell, known in collections as the Glossy
Nautilus, (the Argonauta Vitreus of Greuelin,) is separated from the Argo-
nauta of Lamarck, and considered a new genus, under the name of Carinavia.
Linneus placed it among the Patella, under the name of Patella Crystata. In
the last edition of the Systema Nature, it is placed, with more propriety,
among the Argonauta; but it is still a matter of dispute, that it is what La-
marck styles it, anew genus. The difference between the two genera is
very distinct. In the true Argonauta, the spiral evolution turns into the
opening of the shell; whereas, in Carinavia, the spire is situated at the sum-
mit of the shell, and the mouth entire.
The shells or species are in three divisions.

No. 19. NAUTILUS.
Sail Shell. Inhabitant a Sepia.
Shell univalve, divided into several apartments, communicating with each
other by an aperture or sephunculus. The Linnean Nautili consist of two
principal families; those which are spiral and rounded, and those elongated
and straight. The Nautilus Spirala (Linneus) affords an essential character,
which at once removes it from the Nautili; namely, the last character, which
is alone sufficient to distinguish it. This is a very common West India shell,
but scarcely one has the least vestige of this chamber. The chamber of this
shell is very thin and brittle; and as these shells inhabit deep water, and are
collected only from the rejectamenta of the sea, cast upon the beach in storms,
there is rarely seen a perfect specimen.
The Nautili bear a considerable resemblance to the last genus; like which,
they are often seen floating onthe ocean. The larger kind are entirely marine;
some of the smaller kinds are found in rivers and ponds, frequently adhering
to the leaves and scum of aquatic plants, and to pieces of wood; others are
found only in a fossil state. They are in three divisions.

No. 20. CONUS.
Cone Shell. Inhabitant a Slug.
Shell univalve, convoluted and turbinated, aperture or opening efflute, lon-
gitudinal, linear, toothless, with the base entire, pillar smooth; the total num-
ber of the spires in this genus, in the last edition of the Systema Nature,
amounts to seventy-one. Many of the Cone tribe are beautiful shells, and
bear high prices. Of this genus is the Conus Gloria Maris, which was lately
sold at auction, in London, for the sum of £54 sterling, or $250. The Cedo
Nulli was formerly sold for three hundred guineas.
Most of the Cone shells are covered with an epidermis, under which the
surface bears a most brilliant polish. All the species are marine, and are
generally found on rocky coasts. There is no genus, throughout the whole
of the shell tribes, which holds so important a station in cabinets or collections
as Cones; and it is difficult to decide whether they are most to be valued for
their rarity or beauty. The Admiral Cone ranks first; of this, the varieties
are incalculable: next comes the Vice Admiral, Guinea Admirals, and others
equally rare; most of which, when fine, are of high price in England—from
five to twenty guineas.
There is perhaps no other species, which affords so much beauty and di-
versity of coloring and making as the Cone. The species Literatus, for in-
stance, has its spots arranged in such a manner, as often to resemble Hebrew,
Greek, or Arabic characters. In other species, the colors assume different
shades of cloudings, veins, marblings, dots, stripes, brands, &c. &c., each
surpassing the other in beauty and elegance,

No. 21. CYPREA.
Cowry. Inhabitanét a Limaz.
Shell univalve, involuted, subovate, obtuse and smooth, aperture effuse at
each end, linear, dentated at both sides, and longitudinal. In their young
state, the Cyprea have the appearance of a Volute; insomuch that writers have
been misled, and have classed them among the Voluta.
There is no tribe of shells which, on the whole, are more beautiful than
these. From their high polish and brilliant colors, they have derived the
name (by which they are known in France, most commonly) of Porcelains.
The species are very numerous. In civilized countries, several of them are
used as an ornament for the persons of men and women; and some are worn
as amulets or charms against disease. They reside in the sand at the bottom
of the sea, and are furnished with a membrane which is so extensive, that they
are able to throw it over their whole shells, and thus preserve them always
pure and polished. The animals have two horns, and the canal by which they
respire is situated on the top of their head.
The Tiger Cowry, (C. Tigris,) and Money Cowry, (C. Moneta.)—There
are few shells more common, of the present tribe, in collections, than the
former of these species. It is found both in the Indian and Adriatic Seas.
The latter are well known in almost all the coasts of Africa and India, where
they are employed by the natives, in commerce, instead of money, and about
two thousand of them are esteemed equal to a rupee. The negro women, it
is stated, fish for them usually three days, before or after the full moon; and
thirty or forty vessels are annually laden with them, in the Maldivian islands,
for exportation to Africa, Bengal, Siam, and the adjacent islands, for the
purposes of commerce. Of the Cowries, a very remarkable fact has been
stated by Mons. Brugiere, that when the animals find their shells too small for
the increased dimensions of their bodies, they quit them, and proceed to the
formation of new ones of larger size, and consequently better adapted to their
wants.

No. 22. BULLA.
Dipper. Inhabitant a Slug.
This shell is univalve, convoluted, and unarmed with teeth; somewhat
straightened, oblong, longitudinal, and very entire at the base; pillar less ob-
lique, and smooth. The arrangements of the Bulla family, among the old
writers on the subject, are very confused. Lister makes them a genus of the
Cowry; which one species, the Bulla Remicosa, much resembles. Grew and
Buonanori place it among the snails; Argenville and D’Avila, with the Coch-
lea Globose; and Gaulteri, as a species between the Argonauta Argo and the
Cyprea. The term Bulla, implying the bubble-like form, was applied by
Rumphius to the Bulla Ampula, from whom it was adopted by Linneus as a
generic appellation.
The animal of Bulla Lignaria is furnished with masticatory organs, con-
sisting of three testaceous bodies, placed within the stomach or gizzard, by
the help of which, it is enabled to break small shells and hard substances.
These latter named testaceous substances were first introduced as a new
genus by Gicenia, a Sicilian naturalist; after whom, it was named Gicenia, by
Brugiere. These organs are figured in the Linnean transactions.
The Dippers inhabit the sea, rivers, lakes and ditches. The texture of
most of the sorts is exceedingly thin. The marine kinds are found on shal-
lows, during the recess of the tide.

Volute. Inhabitant a Slug.
Voluta shell single celled and spiral, aperture without a beak, somewhat
effuse, pillar folded or plaited, and generally without lips or perforations.
This genus includes 142 species. Linneus, in the establishment of this new
genus, has been less particular than could have been wished; having brought
together, promiscuously, shells which scarcely agree in one individual respect,
except in having plaits or folds upon the pillar.
The Volute is a very extensive genus; the greater part of which are natives
of the tropical seas, and only found on the shores after storms: but few kinds
are European, and those do not possess any great degree of beauty; while the
tropical kinds are amongst the most beautiful of the whole tribe. The marks
on that called the Music shell, exactly resemble the notes and other characters
used in music.

Whelk. Kihabitant a Limaz.
Shell univalve, spiral, gibbous; aperture ovate, terminating in a short canal
leading to the right, with a retuse beak or tip, inner lip expanded.
The Whelks are found adhering to rocks or stones, beneath the surface of
the ocean; but some few are terrene. Their shells are generally strong,
rough and hollow; and their flesh may with safety be used for food.
The purple-staining Whelks were formerly celebrated, on the coasts of the
Mediterranean, on account of a valuable purple dye, which was extracted
from them. They have, however, of late years, been entirely neglected, in
consequence of the discovery of cochineal, from which a dye equally excel-
lent, and at much less cost, is to be procured. The number of these shells
necessary to be collected together for the purpose of dyeing even a small
quantity of cloth, must haye been very great. The matter for dyeing,
like the ink in the cuttle-fish, is found in a peculiar reservoir, situated in the
upper part of the body, and on one side of the stomach. This reservoir is
very small, being seldom so large as a small pea. A handkerchief stained
with the coloring matter of the Whelk, will retain its brilliancy for many years;
but the purple tint does not appear, till the linen has been exposed for some
time to the action of the sun and air. In Great Britain there are several
kinds of shell-fish which furnish a dye of this sort, but these are seldom
sought after.

Skrew Shell. Inhabitant a Limaz.
Shell univalve and spiral, lip of the aperture often much dilated and pro-
duced into a groove, leaning to the left. The young shells of the Strombus
do not possess the dilated lip, and have, therefore, been referred to different
genera ; an error committed by some of the best early writers.
The greater part of the shells which constitute the first and second divisions,
have their outer lip extended, either in the form of a wing, (hence called
Alate, or Winged shells,) or projecting in distinct linear divisions, or pointed
claws: but these appearances are only manifest in adult shells. These are
all inhabitants of the ocean, and usually found on rocky shores in the African,
Indian, American and European seas : some few are also found in the Medi-
terranean, Red, and Arctic seas.
This genus derives its name from some of its species bearing the resem-
blance to a whipping-top, (s7g0os.) j

No. 26. MUREX.
Rock Shell. Inhabitant a Limaz.
Shell inequivalve, spiral, rough, with membranaceous sutures, aperture oval,
ending in an entire, straight, or slightly ascending®canal. In the last edition
of the Systema Nature, 193 species are described.
The most prominent character which distinguishes the species of this genus
from those of the two preceding genera, consists in the beak being almost in-
variably straight and very much produced, sometimes turning a little upwards.
The Murices are shells of irregular form, arising from their surfaces being
usually armed with spines, knobs, striw, or foliations. The shells of the first
division have the beak considerably produced, and are distinguished from those
of the second, by the spines with which their surfaces are armed. The most
remarkable species is the M. Tribulus, of which there are two varieties; the
more common being called the Thorny Woodcock, and the rarer, Venus
Comb. ‘The latter is one of the most elegant shells of the genus. When
perfect, its exterior is most beautifully adorned with regular rows of thin and
delicate spines.
Inhabitants of the ocean, they are usually found upon rocky shores, within
the influx of the tide. Some few burrow in the sand. Their shells are
mostly rugged, strong and heavy; from which circumstances, they have ob-
tained the name of Rock shells. The Purpurea of the ancients belong to
this genus. From these shells, or rather from their inhabitants, is furnished
the famous Tyrian purple. (See Ezekiel xxvii. 7, 16, &c.) A single vein,
situated near the head of the fish, contains this beauteous coloring liquor.

No. 27. TROCHUS.
Top Shell. Inhabitant a Slug.
Shell univalve, spiral and subconic, aperture somewhat angular or rounded,
upper side transverse and contracted, pillar placed obliquely.
The leading characteristic of the Trochus is the conical shape of its species,
the base being broad, and the whorls gradually tapering towards the apex.
This form prevails, with very few exceptions, throughout the genus. Some,
however, have so strong a resemblance to the Turbo, that frequent mistakes
have been made in their classification. A few species of this genus have
their surfaces smooth; but the greater number are covered with knobs, spines,
tuberculations, or undulations; of which, the Trochus Solaris and the T. Im-
perialis are striking examples. The former has its margin beset with long
spines, placed at regular distances, and, when the shell is perfect, resembling
the rays of the sun, as represented in carved work. Many, when uncoated,
present a brilliant mother-of-pearl appearance; others have only a pearly ap-
erture; and a few exhibit a bronze-like hue. The aperture to the shell, in
this, as well as in many other genera of univalves, is closed by a stony or
horn-like operculum, affixed to the animal.
Most kinds are marine, and some few are found on land, in moist places.
The generality of them reside in deep water; others, in shallows that are
left nearly dry at the reflux of the tide. The species are very numerous, and
several kinds are common to the British shores. The Trochus Conchylio-
phorus possesses the remarkable faculty of attaching stones, and frequently
shells or fragments of shells, to his testaceous covering, during his period of
formation. Mawe says it is highly valued for its rarity and beauty.

No. 28. TURBO.
Wreath Shell. Inhabitant a Slug.
Shell univalve, spiral and solid, aperture contracted, orbicular and entire.
The species which shows the character of this genus best, is the rare Turbo
Scalaris.
Some of the species in this and the preceding genera, are very likely to be
confounded; but, by attentively observing the round or angular form of their
apertures, their proper families may readily be determined. Most of the
kinds inhabit the sea; some, fresh waters; and others are met with on land.
The most valuable marine specimens are fished up from deep waters, or found
adhering to rocks and stones, below high water mark. This is a very ex-
tensive genus, and a very considerable number are found on the shores of
Great Britain. The common periwinkle is there more extensively used as
food, than any of the other testaceous univalves. This shell is easily
gathered, as it is found on most rocks which are left uncovered by the ebbing
of the tide. Children are principally employed in this fishery, and the shells
are sold by measure. They are, in general, used after being boiled, and are
consumed in great quantities by the poor inhabitants of the coast.
The generic name, Turbo, is derived from the Latin, and has the same
signification with the Greek derivative of the preceding genus. This species
is exceedingly numerous, being in ten divisions, with families.

Snail. Inhabitant a Slug.
Shell univalve, spiral, subdiaphanous and brittle, aperture contracted, semi-
lunar, or roundish.
For the new division of Helices, by late writers, see Latrielle Olivica, &c.
The numerous species which compose this extensive genus, are principally
land or fresh-water shells; a very few only being the produce of the ocean.
They are generally of a delicate and brittle structure, and sometimes trans-
parent.
Of the land species, almost every place produces some one or other of the
kinds. They are found on trees, walls, mossy banks, under stones, &c. &c.
Of the aquatic species, some are found on the sea shores, on the banks or
margins of rivers, brooks and ponds, but mostly in shallow waters. They
are very brittle, and exceedingly susceptible of injury. Some of the kinds
are used as food. The species are very numerous: nearly seventy are found
in Great Britain.
The all-wise Creator has denied to these animals the use of feet and claws,
to enable them to move from place to place; but has made them ample
amends, in a way more commodious to their habits and mode of life, by the
_ broad skin along each side of the belly, and the power of motion which this
possesses. By this they are enabled to creep; and by the skin, assisted by
the glutinous slime emitted from their bodies, they adhere firmly and securely
even to the smoothest surfaces. When the snail is in motion, four horns are
distinctly seen on its head; but the two uppermost, and longest of these, de-
serves particular attention, both on account of the various motions with which
they are endued, and also from their having eyes at the extremities. These
eyes appear like two blackish points, and, when taken from the body, are of a
bulbous figure; they have but one coat, and the vitreous, the aqueous, and the
crystalline humors are (though not distinctly) to be seen. The animalis able
to direct them towards different objects at pleasure, by a regular motion out
of the body; and sometimes it hides them, by a very swift contraction into
the belly. Under the smaller horns is the animal’s mouth, and though its sub-
99
stance may appear to be too soft to be furnished with teeth, yet it has no
fewer than eight; with these it chews leaves and other substances, seemingly
harder than any part of its own body, and sometimes bites off pieces of its
own shell. The snail, if its shell be broken, has the power of mending it.
Even when apparently broken to pieces, it will set to work, and, with the
slimy substance they force from their bodies, which soon hardens, they in a
few days close up all the numerous chasms. The junctures are easily dis-
tinguished, and the whole shell, in some measure, resembles an old coat
patched with new pieces. But, though the animal has the power of repairing
its old shell, it is not able to form a new one.
** An inadvertent step may crush the snail,
That crawls at evening in the public path;
Yet he that hath humanity, forewarned,
Will step aside, and let the reptile live.’’
The Esculent Snail (H. Pomatia) is the largest of all the land snails pro-
duced in England. It is found in woods, and under hedges, in Northampton-
shire, and in some of the southern counties. At the commencement of
winter, it carefully closes up its shell, with a thick white cover or operculum,
attached to its body, that just fills up the opening; and, in this enclosed state,
it remains until the commencement of warm weather; seldom appearing abroad
till about the beginning of April.
It is large and fleshy, and, when properly cooked, not unpleasant to the
taste. Amongst the Romans it constituted a favorite dish; but if the account
of Varro is to be credited, they had it of a size much larger than any known
at this time; for this writer assures us that the shell of some of them would
hold ten quarts: and we need not (says Mr. Pennant) admire the temper-
ance of the supper of the younger Plinys, which consisted only of a lettuce
a-piece, three snails, two eggs, a barley cake, sweet cake and snow,—in case
his snails bore any proportion in size to those just mentioned. They kept
these animals in what are called cochlearia, or snail stews. These were gen-
erally formed under rocks or eminences, whose bottoms were watered by
lakes or rivers; and if a natural dew or moisture was not found, they formed
an artificial one, by bringing into the place a pipe bored full of holes, like a
watering-pot, through which it was continually sprinkled. They required
little attendance or food, supplying themselves, in a great measure, as they
crawled about the sides or floor of their habitation. To fatten them, they
were fed on bran and sodden lees of wine.
100
They are, even yet, much relished on some parts of the continent, and are
not always used from economical motives; for at Vienna, a short time since,
seven of them were charged, at an inn, the same as a plate of veal or beef.
The usual modes of preparing them for the table, are by broiling, frying them
in butter, or sometimes stuffing them with force-meat; but in what manner
soever they are dressed, their sliminess always, in a great measure, remains.
The greatest quantities, and the finest snails, are brought from Suabia. Dr.
Brown, who travelled in Vienna a century ago, remarks, that since the mar-
kets were so well supplied with other provisions, he was surprised to meet
with some odd dishes at their tables, such as guinea pigs, and divers sorts of
snails and tortoises. Dr. Townson was shown, at Eylau, a snailery, which
the proprietor informed him was constructed on an improved plan. In. our
island, he says, this might have had the denomination of a patent snailery, or
philosophical snailery.. It consisted only of a large hole, two or three feet
deep, dug in the ground, having a wooden house as a cover. The animals
in this place were fed on the refuse of the garden, which was thrown in to
them. There seems some doubt as to the original introduction of these
animals into England. Pennant says it was by Sir Kenelm Digby; and Da
Costa, that a Charles Howard, Esq., of the Arundel family, brought some of
them, in the last century, from Italy, in the hope of rendering them an article
of food; and, for this purpose, dispersed them about the woods and downs of
Albury, an ancient seat of that family, near Box hill, in Surry. They are
now to be found, in considerable plenty, not only there, but also in several
parts of the confines of Sussex, where
** The snail,
Beneath his home, with slimy trail,
Crawls o’er the grass.”
The Garden Snail (H. Hortensis) inhabits the gardens and orchards of
most parts of Europe, and abounds with a viscid, slimy juice, which it readily
gives out by boiling in milk and water, so as to render them thick and glutin-
ous; and the compound, especially with milk, is reckoned efficacious in con-
sumptions. Snails are very destructive to wall fruit; but lime and ashes,
sprinkled on the ground, will keep them away, and destroy the young brood.
Fruit, already bitten, should not be taken off the tree, for they will not touch
the other till they have wholly eaten the one begun, if it be left for them.

No. 30. NERITA.
Nerite. Inhabitant a Limaz.
Shell univalve, spiral, gibbous, flattish at bottom, aperture semiorbicular or
semilunar, pillar lip transversely truncated, and flattish. There is considera-
ble variation in the form and markings of the Nerite; some are spiral, with
prominent whorls; others have their whorls partly or wholly concealed; some,
again, are umbilicated, while others are perfectly entire and solid; and many
have the umbilicus partially covered by a repand lip, or fissurated nodule.
The back of the shell is sometimes covered with strong, elevated ribs; and,
ina few species, with spines. It is often only minutely striated, and has fre-
quently a perfectly smooth surface and a brilliant polish.
These shells inhabit the shores of the sea, rivers and lakes. Some are
found adhering to sea-weed, pieces of wrecks, or other extraneous substances ;
others are only met with in deep waters, and may be taken in nets. Most of
the kinds are exceedingly beautiful, and the animals are often eaten by the
natives of the sea shores. The species are numerous. Nothing can exceed
the beauty and delicacy of the miniature painting with which many of the
Nerite are adorned ; and, viewed with a magnifying glass, the most highly
finished touches, upon the smallest scale, are discernible upon their enamelled
surfaces. The Polished Nerite are surpassed by none for beauty and variety.
Many are smooth shells, and display a brilliant lustre, under which are dis-
coverable the most superb party-colored marks, bands and dots, that can pos-
sibly be imagined. They are mostly clouded with green, having intermediate
bands of pale pink; but those are considered the rarest, and certainly the most
beautiful, which are of a perfect jet black, having three or four bright scarlet
bands, which run in a parallel direction with the convolutions of the shell.
Some are from India; but the most esteemed are brought from the South
Seas. The aperture or mouth is of a pure white, sometimes having the throat
of a beautifully delicate pale yellow. The N. Littoralis is often gathered in
England with the perriwinkle, as it frequents the same situation. It is, how-
ever, much smaller, and its flesh is not reckoned so good.

No. 31. HALIOTIS.
Ear Shell. Inhabitant a Limaz.
Shell ear-shaped, dilated, spire lateral and nearly concealed, and a longi-
tudinal row of orifices along the surface. Linneus is very particular about
the orifices so conspicuous in this genus. It was for this reason that he re-
ferred the Helix Haliotides to the Helices rather than to the Haliotis tribe;
the shell being destitute of this striking character, though in every other
respect it appertains to the Haliotis rather than the Helix genera. One of
the imperforate kinds (the Haliotis Imperforata, of Gruelin) was previously
described by Hoblins, under the generic appellation of Stonatia ; having the
shell of an oval form, and ear-shaped, with the spire prominent, the aper-
ture ample, entire, and longer than its breadth, disk imperforate. Haliotis
shell, Lister places among the turbinated shells, between the Nerita and Tro-
chus. Gaultieri ranks them among snails, with depressed spires; Adamson,
in the first family of spiral shells; and Lamarck, between the Testacelli,
(which follows the Helices and Neritw,) and the Vermiculaire, or Serpula.
Shells of this kind are very rarely found fossils.
This species are all marine, and are generally found closely adhering to
rocks or stones, within the influx of the tide; and it requires some adroitness
to detach them without injury to the shells. The animal is accounted deli-
cate food. The species are not numerous. It inhabits the sea, near Guern-
sey, andis, likewise, frequently cast upon the southern shores of Devonshire.
The animal is attached by so adhesive a property to the surface of the rocks,
that it requires the utmost force to disengage it; though, by a spontaneous
action, it is able to remove with facility from place to place.

No. 32. PATELLA.
Limpet. Inhabitant a Slug.
Shell univalve, subconic, and without a spire.—Linneus. Patella limpet,
are so named from their resemblance to a little plate, and are more or less
conic without, and concave within. Some of them have the apex entire, others
perforated. The chamber limpets are distinguished by a peculiar kind of pro-
jecting process or lip within; most have the margin entire, but some have an
indent or fissure in that part; again, others are so spiral or wreathed in their
outward appearance, that they resemble rather the trocha than the patella.
Limpets are found in great abundance on rocky coasts, adhering to rocks
and stones. The fresh water species attach themselves to aquatic plants.
They all affix themselves so tenaciously, that it is with difficulty they are re-
moved without injury. The common limpet frequents the same situation as
the perriwinkle, and is equally abundant. Although used by the ancients as
an article of food, it is seldom taken to market. Among the villages along
the coasts of Scotland, this shell-fish is frequently used; and the juice obtained
by boiling, mixed with oatmeal, is held in high estimation. It is considered
in season about the end of May. The chief excellence of the limpet is,
however, as a bait. It is easily obtained from the rocks, with a knife, by the
fishermen, and it is eagerly seized by all the latteral fish sought after. To
the haddock it is very acceptable.

No. 33. DENTALIUM.
Tooth Shell. Inhabitant a Terebella.
Shell univalve, tubular, straight, or slightly curved, with the cavity open at
both ends, and undivided.—Linneus. There are three families. Greuelin
enumerates, all together, twenty-one species of this genus, some of which are
found only in a fossil state.
The shells of this genus are singular; resembling, in miniature, an elephant’s
tusk. The principal distinctions are in magnitude, curvature, and the num-
ber of ribs and grooves with which some of the species are marked.
These shells are all marine; they may be found on sandy banks of beaches
at low water, generally in a perpendicular or oblique direction, beneath the
sand or mud, and are discoverable by a slight depression of the surface.

No. 34. SERPULA.
Worm Shell. Inhabitant a Terebella.
Shell univalve, tubular and adhering, often separated internally by divisions
at uncertain distances. Gaultieri includes the rare Turbo Scalaris among the
Vermiculi. He observes, the spires of the shells are not produced from, or
supported by a pillar, as is constantly the case in turbinated shells; but pos-
sesses, on the contrary, the true character of the spiral worm shells. But,
although we think that this has much truth, yet we should carefully avoid any
useless innovation.
Like the last shell or genus, these are confined to the ocean, and are often
found, in considerable numbers, attached to other shells, stones and plants.
Serpula is derived from serpo, to creep; and has three divisions.

No. 35. TEREDO.
Ship Worm. Inhabitant a Terebella or Ascidia.
The Teredo is furnished with two calcareous, hemispherical valves or
maxille, truncated before, and two others of a lanceolate form; shell tapering,
flexious, and penetrating wood. It is described and figured in Vol. 61, of
the Philosophical Transactions, (see Doner British shells.) Only four species
of this singular genus have yet been discovered; which are termed Navalis,
Aticulus, Clara and Xytoc, carpum granatum. Two of these species of
Teredo are found in holes which they perforate in wood; a third, in the seed
vessels of a plant which grows in the East Indies, and called by Linneus
Xytoc, carpum granatum; and the fourth, the Gigantic Teredo, in mud, at
the bottom of the ocean. On the coast, in the island of Battoo, near Sumatra,
the shells of these are five or six feet in length.
Great numbers of the ship worm, which are supposed to have been intro-
duced from India into Europe, are sometimes found in the sides and bottoms
of ships; so much so as even to endanger their sinking. By means of their
hard and cutting jaws, they are able to penetrate into any timber, except such
as is of an extremely firm and compact substance. They, however, bore as
seldom as possible across the grain; for, after they have -penetrated a little
way, they turn, and continue with the grain, tolerably straight, until they meet
with another shell, or a knot: their course then depends on the nature of their
obstruction; if considerable, they prefer making a short turn back, in the form
of a syphon, rather than to continue any distance across. Colonel Montague
states that he had an opportunity of examining a great number of their shells,
in the dock-yard at Plymouth, G. B., where every possible means have been
tried, to prevent the ravages which are committed by them. Piles which
have not been in the water more than four or five years, though of solid oak,
were found, on examination, to be greatly perforated by them. In the year
1730, the inhabitants of Holland were under serious alarm concerning these
worms, which had made dreadful depredations in the piles that support the
banks of many parts of those coasts. One of the parties who had the care of
the coasts at the time, observed, to his astonishment, that some of the timbers
118
were, in the course of a few months, made so full of holes, that they could be
beaten to pieces with only a little force. Although, when the mud was scraped
off, the perforations did not appear much larger than to admit a pin’s head,
yet the piles, on being split lengthwise, were found to be full of large passages,
or hollow cylindrical ducts, each of which contained a worm, enclosed in its
testaceous tube, which it exactly fitted. The most efficacious method which
has hitherto been discovered, to preserve timber from the ravages of these
worms, is that which is now adopted in the several dock-yards,—to cover all
the parts under water with short, broad-headed nails: these soon cover the
whole surface with a strong coating of rust, which is found to be altogether
impenetrable to the animal.

Sabella with vingent mouth, and two thicker tentacula behind the head;
shell tubulous, composed of particles of sand, broken shells, and vegetable
substances, united to a membrane by a glutinous cement.
Of the Greuelian System, twenty-five species of Sabella, the fresh water
kinds, described by Schroetten, being included. The marine Sabella shells
are composed chiefly of sand and the fragments of shells; those of the supposed
Sabella, found in fresh water, of the small fragments of testaceous Vermes,
particularly Helices. .
It is not at present determined, by the most able conchologists, whether
this genus has a claim to its present situation among testaceous shells; but, as
no better or more natural situation has been assigned to it, we leave it as pre-
-viously arranged. These species are found in the sea, and also in fresh water
ditches; sometimes affixed to rocks and shells, and at others buried in mud
and sand.

HISTORY
OF
CONCHOLOGY.
Tue name of Aristotle stands high in the records of philosophy. He is
called by Dr. Pulteney, ‘‘ the father of testaceological science,”’ and by
Dr. Maton, ‘‘ the inventor of system.’’ The learned world is indebted cer-
tainly to the writings of Aristotle for the first account we shall probably ever
possess of the state of natural science at the period in which he lived. The
classification of shells, contained in the fourth book of Aristotle’s ‘* History of
Animals,’’ has withstood the test of ages, and, with improvements which recent
discoveries have rendered necessary, is in general adoption with late writers.
Linneus himself was, in a great measure, indebted to Aristotle for the out-
lines of his system, for many of his genera, and for the names under which
those genera are retained, even in the most improved state of his system of
Testaceology. The ‘‘ Ostracodermata”’ of Aristotle (for such is the title of
his Conchological works) presents to us a valuable scheme for shelis.
He divides shells into two principal classes, (Movd$vgz and As4uez,) or
univalves and multivalves. Aristotle flourished about 200 years before the
Christian era.
C. S. Pliny wrote largely on Conchology. The ninth book of his History
of Animals is very copious: it is more diffuse than that of Aristotle, and the
arrangement, if not so methodical, is, notwithstanding, a useful work, and may
be consulted with advantage.
After the dark ages, Vincentius Belleracentis was one of the earliest writers
on the subject. The ‘‘ Speculum Nature,’’ published in folio, in the year
124
1494, contains a description of the Murex Purpurea, Ostrea, and a few other
remarkable shells, extracted chiefly from the works of Aristotle and Pliny,
and intermingled with the absurd and superstitious notions of the times. ‘The
work of Albertus Magnus, entitled, ‘* De Animalibus,’’ which appeared in folio
in the year 1795, contains descriptions of some shells, as also that of Adam
Lonicerus ‘‘ Historie Naturalis, opus novum,”’ published 1551.
The first writers who distinguished themselves by any attention to the study
of Conchology, after the revival of literature in Europe, were Belon, Ronde-
letius, and Gesner. Belon is celebrated for his travels in the east; and he was,
perhaps, one of the first learned men who travelled principally with a view to
natural science. On his return to Paris, in 1553, he published, besides
other works, an octavo volume, entitled ‘‘ De Aquatilibus.’’ The part appro-
priated to Conchology is not extensive: it is rather elementary and philo-
logical, than descriptive, but contains figures of a few shells engraved on
wood.
The work of Rondeletius, who was professor of physic, at Montpelier,
appeared two years after. This bears the title of ‘* Universa Aquatilium Histo-
ria,’’ and contains upwards of 100 species of testaceous animals. This author
received much assistance from the labors of Aristotle and Pliny.
In 1558, the work of Conrad Gesner, ‘‘Piscium et Aquatilium Historia,”
made its appearance, and acquired much reputation. The work, ‘ De
Mollibus Crustaceis, Testaceis et Zoophytis,’’ appeared in folio, in 1606.
The figures are merely cuts on wood, and are rudely executed. Fabius
Columna published, in 1616, a treatise on shells, entitled ‘‘ De Purpura ab
animali testacea fusa, de hoc ipso animali aliisque rarioribus testaceis quibus-
dam.”? A new edition of this work, with notes, appeared in 1675, edited by
John Daniel, Major. In 1655, was published at Copenhagen, a catalogue of
the natural and artificial curiosities in the museum of Olaus Wormius. The
sixth, seventh, and eighth chapters of this work are descriptive of shells.
These he divides into Univalvia, Vivalvia, Turbinata. In 1672, an account
of the collection of an Italian nobleman (Count Ludovico Mercardo) appear-
ed at Padua. The shells are comprised in twelve plates, and the subjects
are noticed specifically. Another edition of this work made its appearance at
Verona in the same year; in which, beside the twelve plates above mentioned,
(and which are engraved on copper,) one contains some cuts on wood.
A description of the museum of the Duke of Holstein, issued from the press,
in 1666, edited by Adam Olearius, contains thirty-six plates, five of which
are devoted to Conchology. It is in quarto, and all the plates of shells are
125
referred to by Linneus, in his ‘¢ Systema Nature.’’ In the twelfth volume of
the Philosophical Transactions, is a ‘‘ Relation concerning Bernacles,’’ by
Sir Robert Moray, who asserts, as we have stated, that young geese pro-
ceed from them, and may actually be seen.
In 1681, Grew published his ‘* Museum Regalis Societatis,’’ or catalogue
and description of the natural and artificial rarities belonging to the Royal Socie-
ty, and preserved in Gresham college, London. This was the earliest work of
its kind that appeared in the English language. The shells are described in
two chapters; the first, comprehending univalves, the second, bivalves and
multivalves, illustrated with about 140 figures, to which the current English
names are prefixed.
Buonanni was cotemporary with Grew; and, in the same year, published at
Rome his ‘“‘ Ricreazione,’’? &c., a work of very superior merit, and esteem-
ed the first professedly written at any considerable length on the subject of
Conchology.
There was another edition published in Latin, three years after, with
additions: the first contained a series of 450 figures, the number of which is
augmented to 550 in the Latin edition. These are valuable for reference,
being constantly in request. In the Linnean Systema Nature, the greatest
fault is, that many of the shells are reversed by the inaccuracy of the en-
graver, so that the apertures of the spiral, or turbinated shells, turn to the left.
instead of the right.* :
A production of uncommon merit made its appearance about this time be-
fore the public; the great Conchological work of Dr. Lister, entitled ‘‘ His-
toria, sive Synopsis Methodica Conchyliorum,”’ the publication of which
commenced in 1685. The author had previously distinguished himself by
some excellent dissertations on the same subject; but our attention is princi-
pally directed to this as his most extensive and valuable undertaking. It was
published in folio, progressively, from 1685 to 1692. Lister divides his
work into four books: Ist, De Turbinibus Terrestribus; 2d, De Vivalvibus
Aquedulcis; 3d, De Vivalvibus Marinis et Conchisanatiferis; 4th, De Patellis
Dentalibus, &c., et de Buccinis Marinis.”’ There is no text to this book.
The whole work consists of engravings, with a brief description of the shells,
and reference to their native country, where that could be ascertained, in the
Latin tongue, and sometimes the current English names. The plates, which
are of various dimensions, are executed with great force and delicacy by the

‘
author’s two daughters, Susanna and Ann Lister. It is an extraordinary
circumstance, that no two copies of this work are found alike; which renders
it very complex, and ill suited for general purposes. The plates in the most
perfect copies vary from 1050 to 1067, the different copies having been
augmented or diminished, and the plates transposed or corrected, at various
times, according to the subsequent discoveries of the author.*
The popular work ushered into the world, under the immediate patronage
of Rumphius, claims particular notice. This bears the title of ‘*“Amboynsche
Rariteit Kamer,’’ the Rarity chamber of Amboyna, and contains an
account of the more remarkable natural curiosities in his museum, the pro-
ductions of Amboyna, where they had been collected chiefly by Rumphius
himself. Of 60 plates with which this work is embellished, no less than 33
are devoted to the subject of shells, the total number of which amounts to
about 400; and many of these of great rarity and price in those days. It is
related as a matter of astonishment, that Rumphius himself informs us, a shell
described in his work, cost no less than 500 florins, about $300 of our money.
The sum is great, yet there are few cabinets in Europe that do not in-
clude specimens of equal or much greater cost. Lyonnet estimates the price
of his Cedo Nulli far higher; and many other instances of immense sums being
paid for shells might be adduced. Among the plates illustrative of various
curious subjects contained in the museum of Gottwold, of Dantzic, dated
1714, forty-three are appropriated to shells.
The valuable work of C. N. Langius, ‘‘ Methodus nova Testacea marina
in suas classes, genera, et species distribuendi,’’? was published in quarto at
Lucerne, in 1722. To the writings of this able naturalist, Linneus stands
highly indebted. Gualteri’s work on shells is a standard book of reference,
and, as such, is well known. ‘This is entitled ‘‘ Index Testarum Conchylio-
rum que adservantur in Museo Nicolai Gualteri, &c.’’ It was published in
Latin, at Florence, in 1747, and contains 110 plates of shells, the figures of
the univalves in which are singularly placed on their summit; they are, nev-
ertheless, tolerably correct. The descriptive matter is less interesting.t
*¢ La Conchyliologie,’’ of D’Argenville is a voluminous work, and contains a
vast number of excellent descriptions, and many figures. The first edition
of this work appeared in 1742, and a second, considerably augmented, in
1754: the last edition was published in 1780, with many additions, cor-
rections and improvements, containing also a series of plates of about 2000

figures. The ‘‘ Testaceo-Theologia,”’ of Lepas is embellished with 137 fig-
ures of shells, and abounds with physiological and anatomical observations on
the structure of these testaceous animals. The principal production of Kleins
is ‘ Tentamen Methodi Ostracologie, &c.”’ published at Leyden, in 1753.
Adanson’s ‘ Histoire Naturelle du Senegal,’’ was published at Paris, in 1757.
This useful work contains a new arrangement of Conchology, and a series of
about 400 figures of shells with the animal appertaining to the principal fami-
ilies.
The Testaceological writings of Linneus should now be particularly advert-
ed to. One of the earliest of his productions on this subject, is the ‘* Fauna
Suecica,”’ the first edition of which, was published in 1746, and contains an
- account of sixty different species of Swedish shells. In the description of the
Museum of the queen of Sweden, Linneus possessed a more favorable oppor-
tunity of treating on testaceology, as her majesty’s collection was particularly
rich in shells. This work describes 435 species of shells, and appeared in
1764. In the interval between the times in which the two last mentioned
works were published, Linneus brought out a second edition of the ‘* Fauna
Suecica,”’ in which the number of shells described was augmented from 60
to 89 species. The ‘‘Mautissa Altera’’ contains 35 species, not described in
the other works already mentioned. The ‘‘ Fundamenta Testaceologie”
was one of the latest of his tracts, and is to be found among the ‘‘ Disserta-
tiones Academice.’’ These are valuable works in a limited view; but the
classification of shells in the ‘* Systema Nature,’”’ from the nature of the un-
dertaking is to be considered the most general of all the Linnzan writings on
the Testacea. Between the year 1735, in which that work first appeared,
and 1767, the ‘*‘ Systema’ passed through no-less than 12 editions, in all of
which, a progressive improvement, and nearer approach to perfection are
manifested.
The third volume of the extensive and costly work of Seba, ‘‘ Descriptio
Thesauri Rerum Naturalium ’’was produced at Amsterdam, in 1758. This part
contains, besides plates in other departments, 61 elucidatory of Conchology.
This work is certainly valuable for reference to those species which are well
known; but a profusion of engravings is expended in figuring examples of
shell work, &c., which are entirely unnecessary and useless.
The magnificent work of Regenfres, ‘‘ Choix de Coquillages et de Crus-
taces,’’ appeared at Copenhagen on the same year as the preceding. The
work comprises 12 colored plates, in imperial folio, and each plate compre-
128
hends 12 shells. The shells which are figured by Regenfres, are of the com-
monest species, such as daily fall under the notice of collectors; and it is to
be lamented that the talents of this artist were not employed on subjects better
deserving of elucidation.
D’Avilas’ catalogue was printed at Paris, in 1767, in three vols. octavo.
The first volume treats entirely of shells, and contains 22 plates of the rarer
specimens of his cabinet; many of which are scarce, even at this day.
The splendid work of Martini and Chemnitz, ‘‘ Neues Systematiches Kon-
chylien Cabinet ’’ was in a progressive course of publication. In 1769, the
first part appeared; another in 1771, and a third in 1777: these were all its
author lived to accomplish. Seven volumes have been since added by F.
H. Chemnitz. The body of the work is in the German language: the
embellishments consist of 366 plates, and exhibit a number of figures on
each plate.
The Elements of Conchology, by Da Costa, was published in 1776.
The publication of Born, upon shells, contains about 200 colored figures,
delineated in 18 folio engravings.
Mr. Pennant’s ‘‘ British Zoology” contains, in the fourth volume, an enu-
meration of 163 species of shells, with concise descriptions, and 56 plates,
exhibiting figures of nearly all, which are well described, but most miserable
engravings, so bad that the shell can hardly be recognized. The ‘‘ Zoophy-
tacium Gronovianun,’’ a description of the rich museum of L. T. Gronovi-
us, senator at Leyden, was published in 1781. There are, in this work,
scientific descriptions of 589 species of shells, and among the plates, two
appropriated to the illustration of the rarer kinds.
The grand work on shells, by Martini, entitled the ‘‘ Universal Concholo-
gist,’’ was begun in the year 1784, and continued to be published at uncertain
intervals, till 160 plates appeared.
A small quarto treatise, embellished with three plates, the joint labor of
Boys and Walker, appeared in London, in 1784. This work treats only
of microscopic shells, and the researches of its authors were confined to the
Sandwich Islands, as the title indicates.
In the year 1789, Bruguiére, the well-known traveller in the east, com-
menced the testaceological part of the grand work carried on in France,
under the title of ‘“* Encyclopédie Methodique;’’ but, unfortunately for the
cause of science, this skilful naturalist lived only to complete the first volume,
which goes no farther than the letter C. of the article Vers (worms.) This
work is embellished with many plates, and nearly all the genera.

In modern times, Mr. Woods’ excellent catalogue, Mr. Swainson’s tracts,
Perry’s magnificent quarto, and Dillwyn’s invaluable catalogue all demand
attention. Perry’s book is splendid, rare, and valuable. A copy was in the
possession of the late Mr. Israel Thorndike.
Woods’ plates are, though generally well executed, in some instances
wanting, and in others, redundant in coloring.
I do not mention the Lamarchian system in this treatise; I only regard
that of Linneus.
Lamarck has done much for Conchology; but I consider he has increased,
unnecessarily, the genera of Linneus. Dr. Turton’s books on the subject
are worthy of reference. Burrows’ Elements are well calculated to assist the
learner. I am confident that much important matter has been omitted; but I
trust to the candor of a generous public to overlook such imperfections as
the want of scientific observation alone can give.
There are in Buffon 26 plates of shells, comprising 163 figures. There
are in Rees’ Cyclopedia 21 plates of shells, comprising 120 figures.
In the Encyclopedia Britannica there are four plates of shells, well engraved,
comprising 72 figures of all the genera.
METHOD TO OBTAIN AND CLEANSE SHELLS.
Collectors should always.try to get shells with the animal alive within them.
This can be done by drags or trawling nets, such as fishermen use. After
storms is the best time for the search of shells. Such as have lain long on
the sea shore, exposed to the rain and the sun, become dead and bleached,
which renders them unfit for cabinets. River shells are more frequently of
an obscure color, and remarkably thin. Hard shells, which abound chiefly
in hot climates, are generally very beautiful.
Immediately after extracting the fish which inhabits the shell, is the time to
prepare the shell, so that it need not be injured by the salts contained in the sea
water. When taken, they had better be thrown into boiling water, a suffi-
cient time to destroy the animal; taken out, and put immediately into cold
water, where they must remain till quite cold, when the animal can be easily
taken out.
17
130
Shells, when encrusted with extraneous matter, should be allowed to
steep for some time in warm water, both for the sake of moistening the sub-
stances, and to extract, as muchas possible, the marine salts; they may be allowed
to remain fifteen minutes without injury. After this, brush them well, observing
that the brush for fine shells should not be too hard. If that proves insufficient
to clean them, rub or brush them again with tripoli, (rotten stone) or emery and
fine oil; but I have generally found that strong soap and water answers best:
a ley of pearl-ashes may be used. When clean, finish with a brush and fine
emery. But if the extraneous substance on the shell is found exceedingly
difficult to remove, a weak acid may be used for the space of a minute, dip-
ping into cold water immediately after. The acid may not be more than
from one sixth to one tenth of the liquid (muriatic acid.)
The epidermis, in some instances, may be so thick that it must be taken off
before the shell can be polished. In that case, it is absolutely necessary to
use the acid, as stated, and as often repeated as is found to be wanted to take
off the coating of lime, &c. When acid is used, particular care should be
taken that it acts only on the coat; and therefore it is found convenient, in
some instances, to coat the orifices or mouth with bees-wax. Change the
situation of the shell often, so that every part may be equally noticed
and cleansed. Wipe off the effervescence with a feather dipped in
water, when you perceive the shell free from the epidermis; then take it out
of the water, and wash away the acid; after which, rub it with fine emery
powder until it is perfectly clean.
If it is only a pellicle and not a thick epidermis, it is sufficient to steep the
shell in warm water, or vinegar, until the coat peels off, or is corroded away.
HABITATS.
The West Indies do not produce many rare shells. In Demerara, there
are many land and fresh water shells. The land shells and muscles, which
may be found over the whole of the vast territories of Surinam and Cayenne,
are very desirable. In the interior of Buenos Ayres, there are many fine
shells. From Pernambuco to Bahia and Rio de Janeiro, the land and fresh
water shells are quite as interesting, if not more so, than those which are
found on the coast. To the southward of Rio, near the isle of St. Sebastian,
13k
the Paper Nautilus and other fine shells are frequently met with. The rocks
which form the Falkland Islands, produce very fine Limpets. Many good
shells are brought from Magellan Straits and Staten Island, near Lima, and
on the shores of Callao, many fine varieties have been procured. The Galli-
pagos Islands are rich in shells. From the islands at the entrance of the
Gulf of California, and from the rocks and beach, are found numerous speci-
mens of Haliotis. The shells from the Sandwich Islands are in great request,
especially the Aurantium or Orange Cowry. From the elegant group of the
Marquesas and Society islands, have been brought (chiefly by circumnaviga-
tors) many very rare and beautiful shells. The shells from New Zealand,
New Holland, King George’s Island, Port Jackson, &c., are all valuable,
because scarce. From the coasts of Passera and New Guinea, some very
rare varieties have been brought. The shells from the Chinese seas are
generally interesting; and from the Philippine Islands we have many fine va-
rieties. From Java, Sumatra, and Malacca, many have been brought. From
the Andaman Islands many fine Cones, rare Limpets and Chitons have been
obtained. Madras presents such a surf-beaten coast that no perfect shells are
found there, but many fine varieties have been sent from Tranquebar. We
now come to the famed island of Ceylon, well known to Conchologists for
the rare Volutes found on its coasts, and for the land and fresh water shells
from the interior. From the sand of the Persian Gulf, many extremely fine
shells are found, which bear the distinguished names of Persian Crown, Vo-
luta, Gambronica, &c. The coasts of the great island Madagascar abound
with shells.
The isles of Bourbon and France are highly and deservedly famous for
testaceological pursuits; and it may be remarked, that whatever is produced
there, is the most beautiful of its species. A curious distorted Helix shell
(which is scarce) is peculiar to these islands.
The Maldive and Philippine Islands, Bengal, and the Coast of Malabar,
abound with the most elegant of all the species of Snails. China abounds
with the finest and greatest variety of Cyprea and Snails. Japan furnishes us
with all the thicker and larger bivalves, and the isle of Cyprus is famous for
the beauty and variety of the Patella found there. About Brazil and the Gulf
of Mexico, there are found Murexes of great beauty, and also a great variety
of Cyprea, Buccini, Pectens, Nerita and Cardia. The isle of Cayenne
affords one of the most beautiful of the Buccinum tribe, and the Volute Auris
Midez is found principally about this place. Jamaica, and the shores about
132 ;
Barbadoes, are covered with Cypre, Chama, and Buccinum; and at St.
~ Domingo, there are found all the same species of shells that we have from the
East Indies, but not so fine, the colors being pale and dead. The Pearl
Oyster is found on this coast, but smaller than in the Persian Gulf. About
Canada are found the Violet Chame, and the lakes of that country abound
with muscles of very elegant pale blue and red colors. The great bank
of Newfoundland is nearly destitute of shells: the principal kind found
there, are muscles of considerable beauty. The island of Magellan, at the
southern point of America, furnishes us with a very remarkable species of
muscle, and several very elegant species of limpets. The coast of Tranque-
bar is very rich in shells. We find there a vast variety of the large Cyprea,
many of great beauty. Besides these and many other shells, there are found,
on this coast, all the species of Nautili, many of which are very fine. The
Canary Isles abound with avast variety of Murices, and some other good
shells, and we have from Madeira a great variety of the Echini different from
those of the European Seas. Sea Ears are nowhere more abundant than at
Madeira. The Red Sea, above all other parts of the world, abounds in
shells.
The Mediterranean also abounds much more in shells than the ocean.
The Gulf of Tarentum affords great variety of Murices, Cyprea, Nautili, and
elegant oysters. The coasts of Naples and Sardinia afford the same, and
also a vast number of Solens, of all the known species. The island of Sicily
is famous for a very elegant kind of oyster, which is perfectly white. Pin-
ne and Cyprea are also found in great plenty there, with Telline and
Chamz of many species, and a great variety of other beautiful shells. About
Syracuse, are found elegant Snails, in great variety. Corsica is famous, be-
yond all other places, for the Pinna, and many other beautiful shells.
About Anaconda, are found vast quantities of the Pholades, buried in stone.
Sea Ears are frequently found about Pezzaoli (Buccinumree.) The ports
of Marseilles and Toulon are full of Pinnez, Mitili, Telline, and Chame. The
coasts of Bretagne afford great numbers of the Lepas, Anatiferra, and Pholas.
At Grainville, in lower Normandy, are very beautiful Pectens, and some of
the Cordiform shells. On most of the English coasts, are found Sea Ears
and Dentalia, with Pectens, and elegant varieties of the Telline. Chame are
fished up about Scarborough. Ireland affords Pectens in abundance, and
the Pholades are frequent on most of the shores; also, a great variety of the
Buccina, and some Volute; on the Guernsey coast, a particularly beautiful
133
Snail. About Cadiz, are found large Pinne, and some fine Buccina. The
islands of Majorca and Minorca afford a great variety of elegant shells; the
Baltic, many beautiful species, but particularly an orange colored Pecten,
which is not found in any other part of the world.
TO PACK SHELLS FOR TRANSPORTATION OR REMOVAL.
The method that I should recommend, is in saw-dust; but as_ that is
not always at hand, put some dry sand from the beach, into a chest or beef-
barrel: into this, the large, heavy shells may be put, covering them with sand.
For the more fragile, elegant, and rare shells, it is necessary to provide
small boxes of about a foot square, and according to requirement in depth;
but in no case more than six inches; into which, put a layer of cotton wool,
upon which, one layer of shells, and then filled up with cotton wool: this
will, if packed with care, prevent any fractures, or particles of the finest
shells from being injured, and, of course, rendered of little value. On no
account, pack more than one layer in a box.
