CYPRICARDITES, Conrad, 1841, Ann. Geo. 

 Rep. N. Y., p. 51. [Ely. from resem- 

 blance to the genus Cypricardia.] Equi- 

 valve, profoundly inequilateral; ex- 

 ternal flattened ligamental area ; hinge 

 with four or five short oblique cardinal 

 teeth ; anterior one largest and most 

 prominent; lateral teeth two, short and 

 remote from the cardinal teeth ; two 

 muscular scars ; surface concentrically 

 lined with marks of growth. Type C. 

 curtus. If the genus can stand, it must 

 be based on this type (all other 

 species are referred to other genera), 

 because this species alone has a hinge- 

 line like the one Conrad made.
