The emerald minnow or rosy minnow has a long and thin body 

 and the caudal peduncle moderately short and deep. The great- 

 est depth of the body is contained four and three fourths to five 

 and one half times in the total length to caudal base; the least 

 depth of the caudal peduncle is contained 11^ times in the same 

 length. The greatest width of the body is one half its hight. 

 The head is of moderate size, its length two ninths of the total 

 to caudal base. The snout is short and somewhat pointed, its 

 length one fourth that of the head. Eye large, about three 

 and one fourth times in length of head; mouth oblique, moder- 

 ate, the maxilla reaching front of eye. The dorsal origin is 

 midway between the eye and the base of the caudal, over the 

 17th scale of the lateral line. The base of the fin is two fifths 

 as long as the head, and the longest ray equals the length of the 

 head without the snout. The ventral origin is under the 13th 

 scale of the lateral line, and the fin scarcely reaches to below the 

 end of the dorsal base. The pectoral reaches to below the 

 eighth or ninth scale of the lateral line. The anal origin is 

 under the 24th scale of the lateral line; the base is one half as 

 long as the head, and the longest ray equals the snout and 

 eye combined. The caudal is rather large and deeply forked. 

 The lateral line sweeps downward in a long and shallow curve, 

 becoming nearly median over the anal base. D. ii, 7; A. ii, 9; 

 V. 8; P. 14. Scales 6-39-4; teeth 2, 4-4, 2 or 1, some of them 

 with a slight hook and narrow grinding surface. The specimens 

 described (no. 8735, U. S. National Museum) are 4 to 4J inches 

 long. In spirits the upper parts are light brown, the sides and 

 cheeks silvery, and the belly golden brown; the fins all pale; the 

 width of the silvery stripe equal to diameter of eye. In life the 

 upper parts are greenish; breeding males have the snout rosy. 



The emerald minnow is found in the Great lakes region, the 

 Ohio valley and south to Tennessee, being abundant in lakes
