80 JYotes on Species of CorbiculadoB. 



opportunity of forming a complete suite of the Corbicula sul- 

 catina, I found cause to change my views, and I now consider 

 it as a distinct species. Compared with Corbicula Zargillierti, 

 it is more transverse, less trigonal, the beaks are much less 

 inflated and less raised, the anterior margin is not so broad, the 

 hinge is slighter, narrower, less abruptly curved, and not so 

 strong, and the coloring of the shell is different.

The shell is small, transversely rounded, somewhat com- 

 pressed and nearly equilateral. The sides are rounded. The 

 beaks are moderately full and somewhat raised. The strice are 

 regular and close. The epidermis is green. The interior is 

 violet. The hinge is nearly straight and rather narrow. The 

 lunula is indistinct. The valves are comparatively solid. 



Compared with Corbicula Australis, it is more elongated, the 

 hinge is straighter and broader, the striaa are more regular and 

 the coloring is different. Corbicula minor is larger, more elon- 

 gated, and more oval than Corbicula Angasi, and the disposition 

 of the striee and the coloring are different.
