The silverfin has a moderately elongate body, which is fusi- 

 form in the adult. The caudal peduncle is short and stout. The 

 depth of the body at the ventral fin equals nearly one fourth 

 of the total length to the caudal base. The head is conical, com- 

 pressed and with a pointed snout a little longer than the eye, 

 which is two ninths as long as the head. The mouth is moder- 

 ate, terminal, slightly oblique, the jaws nearly equal, the max- 

 illa reaching to vertical through front of eye. The head is two 

 ninths of the total length without caudal. The dorsal origin is 

 a little behind the ventral origin and over the 15th scale of the 

 lateral line. The length of the dorsal base equals one seventh 

 of the total without caudal, and the longest ray is as long as 

 the head without the snout. The ventral reaches nearly to the 

 anal. The anal begins under the 21st scale of the lateral line; 

 its base is as long as the dorsal base, and its longest ray is 

 about two thirds as long as the head. The caudal is large and 

 moderately forked. The lateral line curves downward over the 

 pectoral. D. 8; A. 9; V. 8; P. 14. Scales 6-38 to 41-4; teeth 

 1, 4-4, 1, with more or less serrate edges. Length of specimen 

 described, from the Susquehanna river, 4 inches. 



In spirits the back is brown, the sides dull silvery, the scales 

 with a dusky margin, and the lower parts are whitish. A nar- 

 row and long black blotch on the membrane between the 6th 

 and 7th and another between the 7th and 8th dorsal rays. 

 Lower fins pale. Males in spring have the fins partly or wholly 

 charged with white pigment, and in the hight of the breeding 

 season the pigment in the dorsal has a greenish tint, and the 

 top of the head and snout is covered with minute tubercles. 



This is one of our finest minnows for the aquarium and is 

 useful as food and bait for larger fishes.
