The spotted shiner has a long and slender body, its greatest 

 depth being nearly one fifth of the total length without the 

 caudal. The caudal peduncle is long and low, its least depth 

 two fifths of greatest depth of body. The width of the body 

 equals two thirds of its depth. The head is moderately large, 

 its length one fourth of the total without the caudal. The 

 snout is long but obtusely rounded at the point, its length one 

 and one half times the diameter of the eye, which is two 

 sevenths of the length of the head. The mouth is small, in- 

 ferior, horizontal, the maxilla reaching to below the anterior 

 nostril and with a small barbel at its hind end. The gill open- 

 ings are separated by a very broad isthmus. The dorsal begins 

 over the 16th scale of the lateral line and slightly in advance 

 of the ventral; the dorsal base is one half as long as the head; 

 the longest ray is as long as the head without the snout; the 

 last ray is as long as the snout. The ventral reaches to the 

 vent, its length one seventh of the total without the caudal. 

 The pectoral reaches to below the 13th scale of the lateral line. 

 The anal origin is under the 27th scale of the lateral line; the 

 anal base is short, equaling the diameter of the eye; the longest 

 ray is as long as the ventral; the last ray is one third as long 

 as the head. The caudal is moderately large and deeply forked, 

 the middle rays one half as long as the external rays. The 

 lateral line is nearly straight and median. D. ii, 8; A. ii, 6; 

 V. 7; P. 15. Scales 6-43-5; teeth 4-4, hooked and with a short 

 grinding surface. In spirits the back is brown, the lower parts 

 are whitish, and the sides are broadly striped with silvery. In
