Shell subovate in lateral view; greatest height 

 median; dorsal margin convex; ventral margin 

 weakly convex ; anterior margin broadly rounded, 

 slightly compressed ; posterior margin less broad- 

 ly rounded. Right valve larger and overlapping 

 around entire margin, least overlap at posterior 

 ventral margin. Surface of right valve smooth. 

 Anterior margin of left valve bears a weak rim 

 more pronounced medially and ventrally, surface 

 otherwise smooth.
