 depressed or flattened, front very slightly raised into a small rounded wave; fold in dorsal 

 valve scarcely defined, sinus in ventral valve very slightly marked ; beak prominent, 

 feebly incurved, with a circular foramen under its angular extremity, surrounded and 

 separated from the hinge-line by deltidial plates. Surface of valves marked by from

Length 8, breadth 8, depth 4 lines. 



Length 9, breadth 10, depth 4 lines.
