The shell is equilateral and somewhat com- 

 pressed. The beaks are tumid. The color 

 of the interior is violet. The lunula is pallid. 

 The sulci are regular. The epidermis is po- 

 lished and of a pale greenish color. The hinge is strong. 



Compared with Corb. Primeana, it is smaller, more equila- 

 teral, fuller, the beaks are more inflated, the sides are less angu- 

 lar, and the coloring is darker. 



I take much pleasure in dedicating this species to Mr. Isaac 

 Lea, who was kind enough to lend it to me for description.
