Isaac Lea described this species from the Savannah River, Georgia in 1838. The shell is elongate with dorsal and ventral margins parallel to each other. The ventral margin is usually concave. Umbos do not extend above the hinge line. The periostracum is dark brown to black. The pseudocardinal teeth are relatively small, and lateral teeth are long and slightly curved. The nacre color is variable from purple to a bluish white to pink.
