|The following description of this species is given by Prof. Forbes: 



Notropis phenucobius.fluH fish unites with a strong general resemblance to Phenacobius the 

 characters of Notropis. The body of the adult is short and deep, the head square, the nose long, 

 and the eyeuuusually large. Length 2.5inches, depth3.5to4 ; caudal peduncle 4 to 4.75. Color 

 in alcohol indefinite ; side.* somewhat silvery, scales along and above the lateral line slightly 

 specked with black. The head is quadrate in transverse section, flat above, 3.75 to 4; nose 

 decurved 34 to 35- interorbital space 2.9 to 3.1. The mouth is inferior, horizontal, rather 

 small, lips, fleshy, not lobed, lower jaw much the shorter, 2.75 to 3.1 in head, upper lip opposite 

 the lower margin of the pupil, upper jaw to posterior margin of nostrils, 3.33 to 3.9 in head 

 Teeth 4-4. Intestine aboutequal to headand body, 0.97 to 1.17. Eye very large, circular, placed 

 high up 3 4 to 3 5 in head. Branchiostegals free from isthmus. Dorsal 1-8, decidedly before 

 ventrals, its length 7 to 8 in body ; anal low, 1-8 ; paired fins rather broad and short ; ventrals not 

 reaching vent, and pectorals falling far short of ventrals, the former 6.25 to G.4 in head and 

 body Thescales are thin large, crowded anteriorly upon the sides, breast wholly naked in allthe 

 specimens seen. Lateral line 35 to 36, longitudinal rows 7 to 9, 13 to 14 beforedorsal. Described
