P. 16.— D. 17.— V. 9.— A. 9.— C. 18 rays. 



This species I discovered in the river Connecticut, 

 ilear Northampton, where it is named Chub Sucker. 



Dr. Mitchill's description of the Cyprinus oblongus, 

 approaches to this; but there are important characters in

 nondescript. 



3. C. tuber culatus. Snout furnished with three tuber- 

 eles, placed in a triangular form, on each side; caudal fin 

 lunated, lobes rounded and equal. 



The 6oJz/of this species resembles much that of the pre- 

 ceding, but it is less elevated on the hack, and more thick; 

 the scales are more equal, are more rounded on the back, 

 and do not crowd on each other near the opercula, as in 

 the preceding; body with seven or eight faint transverse 

 bands; back of a bluish brown colour, sides yellowish or 

 cream colour, abdomen whitish; all ih^fins brownish; above 

 the anal fin, the tail is more inflated than that oithtgibbosus* 

 Xicngth of specimen five inches.

 made known to me by Mr. Titian Peale, the youngest 

 son of Mr. Charles Wilson Pcale, the venerable proprie- 

 tor of the old Philadelphia Museum: a young gentleman 

 whose zeal in the study of Natural History does him 

 much honour. It inhabits the small inland streams of 

 Pennsylvania. The individual described was taken at the 

 country seat of Mr. C, W, Peale, situated near German-
