 souri. 



Although fragmentary, the Kinkaid speci- 

 men conforms to this Keokuk species with 

 respect to the fairly heavy, slightly curved 

 cusp, thin bar with thin, discrete denticles; 

 projection probably slight judging from the 

 scar remaining. 



Kinkaid formation, beds, 5, 6, Johnson 

 County, Illinois.

 Denison Univ. Bull., Jour. Sci. Lab., vol. 35, 

 p. 173, pi. 5, figs. 5, 6; Caney shale, Oklahoma. 



This species with its erect cusp, lens- 

 shaped in cross section, with large appressed 

 denticles, free in upper half, and fluted pro- 

 jection, is typically Mississippian.

Mehl, 1941

 p. 182, pi. 6, figs. 27-41; Keokuk formation, 

 Missouri. 



The Kinkaid species is similar in all 

 respects to that from the Keokuk, e.g., in 



size, shape of bar both orally and aborally, 

 and shape and dentition of the blade.
