Ethalia

''Ethalia'' is a genus of sea snails, marine gastropod mollusks in the subfamily Umboniinae of the family Trochidae, the top snails.

Description

The species are moderate-sized. The orbicular shell is turbinately depressed. The whorls are convex, smooth or transversely striated, the last one rounded at the periphery. They have a mottled or streaked color-pattern. The umbilicus is partly closed by a callus deposit. The columellar lip ends anteriorly in an obtuse dilated callus. The callus emitted at the columellar-parietal angle of the
aperture is tongue-shaped, closing the umbilicus except a rather narrow chink, or even entirely, in some species.

Distribution

This marine genus occurs in the Central and East Indian Ocean, off East Africa, off Indo-Malaysia, and off Australia.
