A terrestrial shell, though the animal that inhabits it is almost amphibious; it greatly resembles the Bulimus, but is easily distinguished by never having the lip reflected or thickened.
Shell very thin, translucid, ovate-oblong, with a conical-pointed spire formed of a small number of whorls; aperture very large, oval, oblique; the edges disunited; the right always acute, the left acute and arched, formed by the columella.
Succinea cucullata.

This genus was so called from the resemblance which the aperture bears to the shape of an ear; many of the species are named from their resemblance to the ears of particular quadrupeds. It is a land-shell, found chiefly in the East and West India Islands.
Shell thick, solid, more or less smooth, oval, oblong, spire short and obtuse; aperture entire, oblong, enlarged, ear-shaped, much contracted behind; edges disunited; right lip sometimes thick and outwardly reflected; the left or columella with one or more teeth or thick callous plaits.
