Stomatella varia, common name the variable stomatella, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.[1]

Description

The size of the shell varies between 6 mm and 17 mm. The polished shell is ear-shaped with an ovate-oblong form.,The back is equally convex. The left side is striated. Its color is buff, varied with white and red. The spire is rather prominent, erect and acuminate.

This is a pretty little species, usually confounded with Stomatella impertusa, but easily distinguished when its profile is examined. The dorsum is equally convex and polished, and the spire is rather prominent, erect and acuminated.[2]

Distribution

This species occurs in the Red Sea and in the Central and East Indian Ocean off Mozambique, Aldabra and Chagos; in the Western Pacific and off Japan, the Philippines, Polynesia and Queensland, Australia.
