apart, the posterior in shape of a band, sometimes very long; ligament
external. Inhabits the British and American seas. Twenty-six species.

                       9. Genus _Capsa_. Pl. VII.

_Animal._ As above.

_Shell._ Transverse, equivalve, valves approximate and close; three
primary teeth in the right valve, and a single bifid tooth in the left,
inserted into a cavity in the opposite one; no lateral teeth; ligament
external and on the short side, as in Donax, from which it was separated
by Lamarck, on account of the peculiarity of the hinge, inhabits the
Indian Ocean. Three species.

                     10. Genus _Crassina_. Pl. VII.

_Animal._ As above.

_Shell._ Distinguished from the Venus by having only two teeth on each
valve, and from the crasatella by the position of the ligament; solid,
suborbicular, thick, hinge with two strong diverging primary teeth in
the right valve, and two unequal ones on the other; ligament external.
Inhabits the Scottish and Devonshire coasts. One species.
