Middle States. I bare no speciraeus referable to this species from the 

 Great Lakes, nor froin tbe Mississiifpi or tbe Obio. If cyprinus, tuini- 

 (his, and danndi.'i are identical, however, oiieof two things must be true. 

 Either C. cijjjrimts really inhabits tbe whole Mississii)pi Valley, but has 

 been overlooked or confounded with others, or else we have a very curi- 

 o*is anomaly in the distribution of the si)ecies, it being an inhabitant 

 of waters of two widely separated areas, having little in common. The 

 former supposition seems the most probable, and I accordingly look for 

 specimens of C. cyprinus in the Mississii)pi Valley.

IlAniTAT.— Mississippi Valley. Abundant in tlie Ohio River. 



This is the njost abundant species of its genus in the Ohio Kiver and 

 its tributari«'s. It is the largest species, the most elongate, and has the 

 lowest fin rays and the smallest head. The ])eculiar enlargement of the 

 anterior rays of the dorsal I have found to be an excellent diagnostic 

 character. This species has been well described by Prolessor Cope 

 under the name of C. nunnnifcr. There can. however, be but little
