Description

The size of an adult shell attains 30 mm, its diameter 8 mm.

The other whorls are convex and crossed by oblique, symmetrically arranged ribs. There are only few in the upper whorls, but numerous (up to fifteen) and of a brown color in the penultimate whorl and in the body whorl They are crossed by transverse nodulose lirations. There is no beading at the sutures. The body whorl shows a dorsal varix close to the outer lip. The long, narrow aperture is white on the interior.
