Specimens from rocky shores are often eroded and encrusted with coralline algae, while those from shell, gravel, or cobble substrata are usually clean.

The base of the shell is nearly flat, with seven or eight concentric close fine lines, which are crenulated in a peculiarly irregular manner by distinct short oblique impressed marks. The interstices are finely radiately striate. The subrhomboidal
