As will appear from the localities given above, this is an abundant and 

 generally distributed fish in Nebraska and South Dakota. It has been found 

 by Professor Meek as far east as Des Moines, and by Mr. A. J. Woqlman as 

 far south as Chihuahua. It was found by us in nearly all the streams which 

 wo examined in .astern South Dakota and in Nebraska. In northwestern 

 Nebraska and in the region in and about the Black Hills we did not find 

 it; and Douglas, Wyo., is the only place in that State where we met with 

 it.' The most western place in Nebraska at which it was obtained is 

 Ravenna. The longest specimens we have are 3i inches long. A fine male 

 from Platto River, Grand Island, is described as follows: Head 4; depth 3; 

 eye 4J; snout 3^; intraorbital width 2f; D. I, 8; A. I, 9; scales 7-36-3, 16 

 before dorsal. Body short and deep, greatly compressed ; back elevated and 

 keel-like before dorsal; head pointed, mouth moderate, terminal, oblique; 

 maxillary scarcely reaching the eye. Dorsal high, its longest rays 1£ in 

 head; anal lower, If in head; pectorals and ventrals short, about If in head; 

 caudal deeply forked, the lobes H in head. Color steel-blue above, belly and 

 all fins, except dorsal, blood-red; dorsal pale; postocular and subocular 

 region red; a violet and crimson crescent behind opercle, changing to dull 

 bluish in alcohol; nose, top of head, nuchal region, and sides along base of 

 anal fin, profusely tuberculate ; middle of side under dorsal fin with a patch of 

 tubercles. In other specimens the caudal peduncle is thickly covered with 

 strong tubercles. Very small individuals, not over If inches long, are 

 strongly tuberculate and brightly colored, and have evidently reached the 

 breeding age. The females average slightly smaller than the males and are 

 not brightly colored.
