Description. — Shell elongate, much compressed, inequilateral, length equal to 

 more than twice the height. Anterior margin rounded, curving rapidly to join 

 the slightly curved ventral margin. Posterior margin oblique, forming an angle 

 with the ventral margin. A shallow furrow passes from the umbo to the middle 

 of the ventral margin. Umbones small, curved forward. A sharp carina extends 

 in a curve from the umbo to the postero-ventral angle, and cuts off a narrow, 

 flattened, postero-dorsal area. Ornamentation consists of fine radial ribs on the 

 anterior and posterior parts of the valves, especially just in front of the carina ; 

 growth-lines distinct.
