Head 4i ; depth 4| ; eye large, 31 in head. D. 8 ; A. 7 ; scales 8-42-6 ; teeth 

 4-4, with grinding surface, and slight hook. Body stout, somewhat 

 compressed, broad and flat above, with deep caudal peduncle. Head broad 

 and flat above, with an angle at the temporal region. Muzzle broad and 

 obtuse, less truncate than in Pimephales notatus. Mouth rather small, but 

 larger than in Pimephalcs, horizontal, terminal, the jaws about equal, max- 

 illary not reaching to opposite anterior margin of eye. Dorsal inserted 

 above ventrals, nearer snout than caudal. Scales before dorsal small and 

 crowded, as in Pimepliales, in about 28 series. Dusky yellowish; sides 

 silvery, with an obsolete dark lateral band, which terminates in a jet- 

 black spot ; a very distinct black spot on anterior rays of dorsal about 

 halfway up. Length 3 inches. Strongly resembles Pimephalcs notatus , 

 but more silvery, less plumbeous, and the black spots more sharply defined.
