A few valves. 



I think this species answers to the requirements of the diag- 

 nosis of Protocardia, sect. Nemocardium. Copying from Dr. 

 W. H. Dall, Trans. Wagn. Free Inst. Sci., vol. iii, part v, p. 1078, 

 they read as follows : — 



Genus Protocardia, Beyrich. Zeitschr. f. Malak., 1845, p. 17. 

 — Shell globose with a posterior area sharply distinguished by 

 sculpture from the rest of the surface ; closed ; hinge normal, 

 with no lunule or escutcheoii. 



Sect. Nemocardium, Meek, Pal. Upper Missouri, 187t5. p. 172. 

 — The posterior area spinose or tuberculate, the remainder of 

 the surface finely radially striate or finely reticulate ; the 

 anterior laterals springing from the umbo)\al cavity.
