The shell is transversely oval, somewhat compressed, and 

 very inequilateral. The lateral margins are rounded. The 

 beaks are small, raised, acute, they curve inwardly, they 

 are approximate and very much inclined. The valves are 

 slight. The interior is pale violet. The striae are regular. The 

 epidermis is pale greenish with violet markings on the beaks, 

 and is polished. The hinge is quite narrow and nearly straight. 

 The posterior lateral tooth is longer than the posterior tooth. 

 The lunula is oval and yellow. 



The very inequilateral appearance of this species renders it 

 quite distinct.
