Mollusks

_Shell._ Transverse, inequilateral, somewhat rounded or suboval; sides
slightly gaping; hinge with one or two cardinal teeth, and a narrow
groove for the internal ligament; ligament double, the external one
short, the internal one fixed in the internal grooves. The two ligaments
distinguish this genus from all other bivalves. Inhabits the West Indian
and American seas. Forty-five species.

                      1. Genus _Corbula_. Pl. VI.

_Animal._ Unknown.

_Shell._ Tolerably solid, regular, inequivalve, inequilateral with a
conical, flexed, ascending, primary tooth in each valve; a cavity at the
side; no lateral teeth; ligament interior, placed in the cavities; two
neighbouring muscular impressions. Inhabits the British and American

                      2. Genus _Pandora_. Pl. VI.

_Animal._ Body much compressed, somewhat elongated, in form of a furrow,
in consequence of the union of the edges of the mantle, and its
continuation with the tubes, which are united and short; foot small,
thickest in front, and issuing through a tolerably large cleft in the
mantle.

_Shell._ Regular, white, elongated, much compressed, inequivalved,
inequilateral; right or upper valve quite flat, with a fold; summits
feebly marked; hinge anomalous, formed by a transverse cardinal tooth on
the right; valve entering a corresponding cavity in the left; ligament
internal, oblique, triangular, inserted in a somewhat deep pit, with
edges a little projecting on each valve; two round muscular impressions.
Inhabits the Mediterranean, British, and American seas. Four living
species, and two fossils, according to Defrance.
