In the stone roller the body is moderately stout and not 

 greatly compressed; the caudal peduncle long and deep. The 

 greatest depth of the body is contained four to four and one 

 half times in the total length without the caudal; the depth of 

 the caudal peduncle, eight and one half to nine times in the 

 same length. The snout is obtuse, twice as long as the eye, and 

 two fifths as long as the head. The maxilla reaches to the ver- 

 tical from the posterior nostril, which is more than twice as far 

 from tip of snout as from eye. The dorsal origin is over the 

 :20th scale of the lateral line, and the ventral origin under the 

 19th. The dorsal base is one half and its longest ray two 

 thirds as long as the head. The ventral reaches nearly to vent. 

 The pectoral is one sixth of total length without caudal. The 

 anal origin is under the 32d scale of the lateral line; the anal 

 base is as long as the snout, and the longest ray equal to head 

 not including the snout. The caudal is moderately forked. D. 

 8; A. '7 or 8. Scales 8-52 to 53-8; teeth 4-4. 



Color in spirits brownish above, lower parts pale. In living 

 examples the scales are somewhat mottled with blackish, and 

 there is a dusky vertical bar behind the opercle; dorsal and anal 

 :fins olivaceous in females and with a nearly median dusky cross 

 bar. Breeding males have the iris orange, the dorsal and anal 

 fins crimson, and the head and sometimes the body covered with 

 large roundish tubercles. 



The stone roller is likewise called stone toter, stone lug- 

 ger, and steel-back minnow. It is a fish of very wide distribu- 

 tion, ranging from western New York to North Carolina and 

 throughout the Ohio and Mississippi valleys, west to Wyoming
