Name: The Conchologist's First Book: A System of Testaceous Malacology, Arranged Expressly for the Use of Schools, in Which the Animals, According to Cuvier, Are Given With the Shells, a Great Number of New Species Added, and the Whole Brought Up, as Accurately as Possible, to the Present Condition of the Science.

Mollusks

_Animal._ Long, subcylindrical, the mantle closed in all parts,
prolonged behind by two long tubes, thick and close together externally,
pierced interiorly and in front with a round orifice, for the passage of
a very small foot; mouth very large; labial appendages small; branchial
laminæ free, the external pair much shorter than the internal.

Lamarck has thought proper to remove this genus from the Mytilus; it
possesses the faculty, like the Pholas, of penetrating rocks and
substances, and cannot be extracted but by breaking the substance in
which it is imbedded.

_Shell._ Thick, with an epidermis, a little irregular, elongated,
subcylindrical, obtuse at both ends; summits feebly marked; hinge
toothless, or with a very small rudimentary tooth; ligament external,
somewhat inflated; two round muscular impressions distinct, and several
others irregular. Inhabits the British and American seas, in cavities,
which they bore in rocks or wood. Nine species.

 Saxicava rugosa.
 S. gallicana.
 S. veneriformis.
 S. pholadis.
 S. Australis.

_Animal._ Unknown.

_Shell._ Subtrigonal, more or less irregular, transverse, inequilateral;
upper side narrowed and a little gaping; lower side rounded; hinge with
two teeth in each valve, or in one valve only. Inhabits the Australian
seas, boring into wood and rocks. Thirteen species.

                    3. Genus _Venerirupis_. Pl. VII.

_Animal._ Unknown, but probably resembling the Venus.

Another lithophagous shell, taken from the genus Venus, and
distinguished from it by the different disposition of the teeth.

_Shell._ Transverse, inequilateral, posterior side short, the anterior
gaping slightly. Hinge with two teeth on the right valve, three on the
left, and sometimes three on both—these are small, near together, and
parallel. Ligament exterior. Inhabits the British seas, boring into
rocks and clay. Eight species.

                              FAMILY VIII.

                         NYMPHACEA. Ten Genera.

This family is divided into N. Solenaria and N. Tellinaria, from their
resemblance to the Solen and Tellina.

N. SOLENARIA. Three genera.


                   1. Genus _Sanguinolaria_. Pl. VII.
