Description

The ear-shaped shell is extremely thin, even membranous in part and concealed in the mantle. It has a small spiral turn at the apex. The aperture is very large. The shell lacks a columella.

The soft body is elliptical and much depressed. The borders of the mantle are very thin, notched in front and spreading out widely. The oval foot is very small. The head is scarcely distinct. The two short and rather thick tentacles are contractile and concealed under the shield. The eyes are situated at the base of the tentacles.[3]
