There is a wide variation in the outline (from longitudinally oval to isometrical), and in convexity (equally biconvex or ventribiconvex) of the shell. The ribs arise at different distances from the beak, and their number varies from 9 to 11. One rib on the ventral sinus and two on the dorsal sulcus are constant but they are developed differently depending upon the outline and convexity of the shells. The internal structure is characterized by thin, short dental plates, divided cardinal plates, and obliquely inclined crura (
