verse, the teeth are less robust and the interior coloring not the 

 same. In fact it is more closely allied to Corbicula Crosseana 

 than to any other species. It differs, however, in being smaller, 

 more solid, more equilateral, and more transverse ; the posterior 

 side is less protruded, the coloring of the interior is not the 

 same, the epidermis is more highly polished, and the lunula is 

 more distinct.

The shell is oval, equilateral, and somewhat compressed. 

 The lateral margins are obtuse. The beaks are small, and when 

 denuded show a blackish-violet under surface. The interior of 

 the valves is highly polished and of a blackish-violet color. The 

 hinge is narrow and slight, and not much curved. The color of 

 the teeth is lighter than that of the rest of the interior. The 

 sulci are regular, close, and not much raised. The epidermis is 

 pale greenish and polished. 



Compared with Corbicula Jfanillensis, this species is not so 

 inflated and more transverse, and the striie are more delicate, 

 closer, and more regular.
