Desmption. — Body stout, moderately elevated, somewhat compressed; head heavy, 

 broad above, the snout moderate, somewhat decurved ; month moderate, obliqne, its 

 jaws equal, the upper lip on a level with the middle of the pupil, the maxillary reaching 

 the front of theeje; eye very large, two and three-fifths in head, much longer than 

 snout, larger than in any other American Cyprinidse ; fins moderate, the dorsal directly 

 opposite ventrals, the tips of the ventrals opposite the last dorsal ray ; scales large ; 

 fitteen in front of the dorsal ; lateral line much decurved ; olivaceous, scales above dark- 

 edged ; sides and below bright silvery ; no red; head 3f; depth 4J ; D. 8; A. 9 ; scales 

 6-39-2 ; teeth 2, 4-4, 2. Length 5 inches. 



Habitat, Ohio Valley. 



Diagnosis. — The great size of the eye, larger than in any other min- 

 now chiefly distinguishes this species. 



Habits. — This species is abundant in White River, Indiana, in which 

 stream the original type was taken. It there frequents the river chan- 

 nel, in company with dintmus, a species which it much resembles both 

 in size and color. It doubtless occurs in Southern Ohio, but I ha*ve no 

 specimens from that State. In fact, with the single exception of a 

 specimen from Kentucky, preserved in the United States Museum, I 

 have Been no specimens except from White River, and none others have 

 been recorded. This species is very handsome, and is desirable for 

 aquaria.
