The length of the shell varies between 2 mm and 4 mm.
The thin shell is somewhat solid, white or brownishand opaline. It is rather numerously longitudinally costulate with riblets vanishing on lower part of body whorl. It shows less prominent, close, spiral striae that are stronger at the base. The shell contains five convex whorls, with a deep suture. The aperture is expanded below and externally varicose. [2]

Fossils have been found in Pleistocene strata near Messina, Sicily.
