*Leuciscus estor, (Jordan & Brayton): Head 3%; depth 4%; eye 4. D. 8; A. 8; scales 8-50-5 

 teeth 2, 5-4, 2. Body elongate, compressed, the caudal peduncle rather long, but not so long as 

 head. Head very long and large, flattish, but not broad above. Mouth larger than in any 

 other of our Cyprinidse, very oblique, the upper jaw on the level of the pupil, the maxillaries 

 extending to opposite middle of orbit; length of gape a little more than half length of head; 

 lower jaw considerably the longer. Eye rather large, less than snout. Scales moderate. 

 Lateral line strongly decurved; 23 scales in front of dorsal fin; fins high. Color dark olive 

 above, many scales irregularly darker; sides silvery; no dark lateral band; a broad shade of 

 deep rose color along the sides in spring males, below which most of the belly is bright crimson, 

 these red colors brightest anteriorly; a narrow dark lateral streak like a pencil mark, from 

 head to tail, overlaid by the scales. Length 4 inches. Cumberland and Tennessee rivers; in 

 clear brooks; not very common. Perhaps a distinct species, but we are unable to find constant 

 characters for distinction. (Type, No. 31147. Coll. Jordan & Brayton.)
