scales below 1. 1. usually 5, rarely 6; predorsal scales usually 19 or 20, 

 rarely 17, 18, 21 or 23; snout 2^ to 3 in head; eye 2f to 3^; maxillary 

 S^ to 3 J; interorbital 3 to 4; teeth 4-4. Body elongate, slender, 

 compressed. Caudal peduncle long, slender. Head long, robust, 

 little deeper than broad. Snout convex, long as broad. Eye large, 

 high, midway in head. Mouth small, inferior, upper jaw protruding 

 slightly. Maxillary well short of eye, ending in short barbel. Inter- 

 orbital flattened. Rakers 2 + 5 short points. Scales smaller on pre- 

 dorsal, well exposed. L. 1. complete, nearly straight. Dorsal origin 

 midway between snout tip and caudal base. Anal origin little behind 

 depressed dorsal tip. Caudal forked. Pectoral 7^- to ventral, latter 

 inserted little behind dorsal origin, fin | to anal. Color olivaceous, 

 back rather mottled, below white. Sides bright silvery- white. Fins 

 pale, plain. Lateral bluish stripe around snout, overlaid with several 

 dusky spots. Length 2^*6- to 4 inches. Twelve examples from the

Found in the channels of the larger streams, creeks and lakes, w^st 

 of the Alleghanies. It does not appear to enter the small brooks. 

 Said to reach 6 inches in length, and though a good biter most too 

 small as food. Taken largely for bait.
