Mollusks

_Animal._ Much compressed; edges of the mantle very fine; not adhering,
and furnished exteriorly with a row of tentacular filaments; contractile
muscle thick, divided into three parts, the largest of which passes
partially across a slope of the inferior valve, and often contains a
calcareous substance or small bone, adhering to marine bodies.

_Shell._ Adhering, irregular, inequivalve, inequilateral, ostraceous;
inferior valve a little flatter than the superior, divided at the summit
into two sloping branches, whose approximation forms a large oval hole;
the superior valve, which is the larger, has an oval excavation under
the summit; a subcentral muscular impression, divided into three parts.
Inhabits the British coasts. Two beautiful species are found on the
shores of Rhode Island and New Jersey. Nine species.

 Anomia patellaris.
 A. pyriformis.
 A. lens.
 A. cepa.
 A. electrica.
 A. membranacea.

_Animal._ Body much compressed and rounded; mantle open throughout its
whole circumference; two ciliated tentacular appendages.

_Shell._ Orbicular, much compressed, inequilateral, very inequivalve;
inferior valve very thin, adhering, imperforated, the superior
patelloid, with the summit more or less inclined towards the posterior
side. Inhabits the Norwegian seas. One living species. Two fossil.

 Orbicula Norwegica.


                    2. Genus _Terebratula_. Pl. IX.

_Animal._ Depressed, circular or oval, more or less elongated, with two,
long, pectinated, labial tentacula.

_Shell._ Thin, inequivalve, regular, subtrigonal; one of the valves
larger and more dilated than the other, which is sometimes operculiform;
hinge condyloid, in a straight line, and formed by two oblique articular
surfaces in one valve placed between corresponding projections in the
other. Inhabits the sea at the Zetland Islands. Two species are found in
America. Thirteen living species. Thirty-eight fossil.
