Description edit
The length of the shell varies between 2 mm and 4 mm.
The imperforate shell is thin, subpellucid and a little shining. It is whitish or yellowish. It has a clathrate sculpture by longitudinal riblets, and much stronger, distant spiral ridges. The shell contains six convex, angulated and shouldered whorls with a deeply incised suture. The aperture is smooth within and slightly varicose externally. [2]
Distribution edit
This species occurs in the Mediterranean Sea off Algeria, Tunisia and Sicily.
