The body is elongate, little compressed, slightly arched ante- 

 riorly, its greatest depth contained three and one third times in 

 the length to end of scales. The head is moderate, flat and 

 broad above, its length less than one fourth of the total without 

 the caudal. Mouth slightly inferior; upper lip thin, lower 

 strongly V-shaped; eye large, about one half as long as the 

 snout, which is rather blunt and does not project much beyond 

 the mouth; fins all well developed. The dorsal is large; its first 

 ray is as long as the base of the fin, or about seven eighths as 

 long as the head. Upper margin of dorsal nearly straight. 

 Pectorals nearly reach to ventrals; the upper caudal lobe nar- 

 row and longer than the lower. D. 15; A. 7 to 8; V. 8. Scales 

 5 to 6-43 to 46-4 to 5. Here described in part from a specimen 

 measuring 16 inches, from Ohio. 



The white-nosed sucker is found sparingly in the Ohio river 

 and the Great lakes region; widely distributed, but nowhere 

 abundant. Cuvier and Valenciennes received from Milbert a 

 specimen sent from Lake Ontario, measuring about 2 feet. Dr 

 Jordan says this is very closely related to the common red 

 horse, from which it can hardly be distinguished except by its 

 fins. Dr Evermann collected a single specimen at Fox island, 

 N. Y. June 29, 1894; he also obtained a specimen, 12 inches long, 

 at Poiutbreeze N. Y. Aug. 21, 1894, which he refers to this 

 species, though indicating some characters in which it differs 

 from the normal form of the white-nosed sucker.
