rotmulato, postico breviore, snbobtuso ; margarita 

 violacea ; cardine incrassato, arcuato ; dentibus late- 

 ralibus praslongis; striis regularibus, remotis ; epi- 

 derrnide nitente, viridi fuscescente vestita ; lunula

The shell is rounded, trigonal, equilateral,

obtuse and shorter. The beaks are small, 

 slightly inflated, and they curve inwardly. The interior is 

 violet. The hinge is rounded and strong, the lateral teeth are 

 considerably elongated. The strice are regular, somewhat dis- 

 tant, raised and sharp. The epidermis is of a soiled greenish- 

 brown color and polished. The lunula is quite distinct. 



Somewhat allied to Corbiciila 3/alaccana, it is however more 

 trigonal, less transverse, less inflated, the hinge is more curved, 

 the interior is darker, the striae are more regular, and the color 

 of the epidermis is not the same. It is smaller and more equi- 

 lateral than either Corbicula difficilis or Corbiciila leviuscula, 

 and it is more trigonal, smaller, and less inflated than Corbicula 

 cor. 



I take much pleasure in dedicating this species to Mr. Th's 

 Bland.
