A large number of specimens of this species are before me 

 and they show a considerable amount of variation in form and 

 color. In the type the left valve is a little higher than the right, 

 but this character is not constant. I do not think that Lea's 

 Anodonta leniicularis, the type of which is before me, differs 

 even varietally. 



Anodontites granadensis (Lea). 



Shell elliptic rhomboid, convex, inequilateral, scarcely sub- 

 solid, the outline being almost evenly elliptical except that the 

 dorsal slope is somewhat obliquely truncated ; posterior ridge 

 full, rounded ; epidermis concentrically striate, slightly wrink- 

 Jed and looped, deep green with a straw-colored area at the 

 base of the shell in front of the posterior ridge, and occasion- 

 ally two or three posterior rays ; nacre blue, purplish or flesh- 

 colored, iridescent. 



Length 36, height 22, diam. 14 mm.
