Shell about three quarters of an inch long, and more than two 

 inches broad, white, brittle, diaphanous, and finely striated 

 concentrically; the beak occupies about one third of the 

 breadth, and the valves shut close, except at its end, which is 

 open ; the inside is delicately white. — Olivi describes his

 bly belongs to this species.

 truncated, and from both in its rugged and distorted shape.
