Mollusks

_Animal._ Thick, oval, foot compressed, falciform, geniculated mantle
closed behind, and pierced by two oval apertures with cirrous edges: no
veritable tubes.

_Shell._ With epidermis; thick, regular, substriated longitudinally,
sub-cordiform, equivalved, inequilateral; summits strongly flexed to the
front and often contiguous; hinge thick, subsimilar, formed by three
slightly converging cardinal teeth, and by a posterior lateral tooth,
sometimes obsolete; ligament very thick; muscular impressions distant,
subcircular, and united by a narrow marginal band. Inhabits the Atlantic
Ocean and British seas. Two living species. Seven fossil.

 Cyprina tennistria.
 C. Icelandica.


                     2. Genus _Cytherea_. Pl. VII.

_Animal._ Oval or round, generally but little compressed; edges of the
mantle undulous, and garnished with tentacular cirri in one row; foot
considerable, compressed, trenchant, in other respects diversiform;
tubes tolerably elongated, and most usually united; mouth small; labial
appendages quite small; branchiæ wide, short, free, or not united either
with one another or with those of the opposite side.

_Shell._ Solid, equivalve, regular, inequilateral; summits equal,
reflexed, and slightly projecting; four primary teeth on one valve, of
which three are divergent, and approximating at the base, and one
remote—this circumstance easily distinguishing it from the Venus. On the
other valve are three primary divergent teeth with a distant cavity
parallel with the edge. Inhabits the British, Mediterranean, and
American seas. Eighty-three living species. Nine fossil.
