The whorl profile shows that the conch is widest in the midflank area; the flanks stand parallel and are weakly convex. They converge towards the umbilicus to form a shallow groove, from which the umbilical margin is elevated like a low rim. The flanks also converge towards the narrowly rounded venter, which is separated from the flanks by a rather deep ventrolateral groove. The shell ornament is visible in a small area near the aperture and shows very weak growth lines.
