Mollusks

_Animal._ Body oval, much compressed, or subcylindrical; the mantle
enclosed only in the half of its inferior side: foot small and
projecting but little beyond the abdominal mass, tubes long, distinct or
united. This genus is perfectly distinct from the Mactra, to which it
formerly belonged, on account of its having no lateral teeth. It is
called by De Blainville, Lutricola, from its being found very deep in
mud or sand at the mouth of rivers.

_Shell._ Oval or elongated, regular, equivalve, more or less
inequilateral, sometimes but slightly gaping: edges always simple and
trenchant; summits feebly marked; hinge subsimilar, formed by two very
small divergent cardinal teeth; two very distinct muscular impressions
united by a palleal impression profoundly sineous to the rear. Inhabits
the seas of Europe and America. Fourteen species.

_Animal._ Body oval and pretty thick; edges of the mantle thick, smooth,
or without tentacular papillæ, augmented behind by two indistinct tubes;
mouth small and oval; labial appendages narrow; branchial laminæ very
small, and united in their length among themselves and with those of the
opposite side; foot oval, trenchant, very long.

_Shell._ The Mactra has a peculiar hinge distinguishing it from all
other genera. It is triangular, with a curved or angular compressed
tooth on each valve, with a small oblique cavity on each side, to which
is attached the ligament. Two lateral teeth, one near the primary tooth
and one near the ligament. The shape of the shell is subtriangular or
oblong; exterior smooth, striated, or ribbed transversely; two muscular
impressions united by a narrow marginal tongue. Inhabits the British and
American coasts. Forty-four species.
