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



Notropis phenacobius.—Thiti fish unites with a strong general resemblance to PheHacubius the 

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

 and the eye unusually large. Length 2.5 inches, depth 3. 5 to 4 ; caudal peduncle 4 to 4.75. Color 

 in alcohol indefinite ; sidej somewhat silvery, scales along and ahovo the lateral lino slightly 

 specked with black. The head is qu.idrate in transverse section, fiat above, 3.75 to 4; nose 

 decurved, 3.4 to 3.5; 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 liji 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 about equal to head and 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; iiaired fins rather broad aud short ; ventrals not 

 reaching vent, and pectorals falling far short of ventrals, the former 6.25 to 6.4 in head and 

 body. The scales are thin, large, crowded anteriorly uiiou the sides, breast wholly naked in all the 

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

 from 10 specimens, the only ones seen, all taken at Peoria.
