Outline: Subcylindrical, anterior greatly reduced; anterior dorsal margin short, mostly continuous with rounded anterior; ventral margin long, almost straight; ligament margin slightly inclined then slightly angled with remainder of long posterior dorsal margin; posterior not greatly expanded, subtruncate. Posterior area set off by a low umbonal posterior ventral margin ridge.

Sculpture: Of irregular concentric ridges and lines. Margin: Inner margin smooth. Ligament: External, sunken, becoming relatively extensive extending to 1/3 of length of posterior dorsal margin. Hinge: Hinge teeth usually worn but RV with a single peg-like cardinal; LV with two similar cardinals.

Depth Range
Intertidal
Continental Shelf (to 200m)
