Reviai'ks. — This species is the same figured by Prof. Harris 

 (Bulletins Am. Pal., Vol. i, p. 182) as a cast. It is rather com- 

 mon but so very fragile it was almost impossible to procure a per-

Tellina cynogSossa Dall. 



This is the common species in the Woods Bluff beds. It 

 seems to be only a variety of Tellina subtriangularis Aldr., which 

 was described from half grown specimens, which is more regu-
