HABITAT. Mississippi Valley ; generally abundant. 



This species is closely related to C. vclifer, but differs in the abruptly 

 truncate snout, that of velifer being conic. I am unable to recognize 

 C. selene as a distinct species at present, the form of the anterior sub- 

 orbital being the only distinguishing feature of much importance, and 

 that probably not a constant one. C. cutisanscrinus is as abundant in 

 the Ohio as C. velifer, and I have seen many specimens from the Illinois 

 Eiver.
