164 NORTHERN FISHES 



The Topeka shiner ranges from southern Minnesota through Iowa 

 into Kansas. Hubbs reports that he has identified specimens of the 

 Topeka shiner from a creek 16 miles east of Austin. There are no speci- 

 mens in the University of Minnesota collections. This fish is rather 

 southern in distribution and in Minnesota is probably restricted to the 

 extreme southern part. 



NORTHERN MIMIC SHINER 



Notropis volucellus volucellus (Cope) 



This is a rather slender minnow with a lateral band which is some- 

 what broken anteriorly. The lateral-line scales number 35-38. The 

 exposed surface of the lateral-hne scales is about two to three times as 

 high as long. The mouth is small, the length of the upper jaw being 

 about equal to the diameter of the eye. The pharyngeal teeth are 4 — 4. 

 This minnow reaches a length of over two inches. 



The northern mimic shiner ranges through southern Canada south- 

 ward into Minnesota, Kentuckj-, and both drainages of North Caro- 

 lina. This species is common in lakes of north central Minnesota, such 

 as Leech Lake, Cass Lake, Cut Foot Sioux Lake, and Lake of the 

 Woods. It has been found also in Cottonwood County in southern 

 Minnesota. Greene (1935) reported it from the St. Croix and St. Louis 

 rivers and as widespread in Wisconsin. 



CHANNEL MIMIC SHINER 



Notropis volucellus wickliffi (Trautman) 



This subspecies ranges in the Mississippi drainage from Minnesota 

 and Iowa eastward to Ohio and Kentucky. Greene (1935) reported the 

 channel mimic shiner as confined to the Mississippi River, but it has 

 been collected also in other major rivers of Minnesota. 



GHOST MIMIC SHINER 



Notropis volucellus buchanani Meek 



The ghost mimic shiner is another subspecies reported by Greene 

 (1935) from the Mississippi River in Iowa just below Minnesota. 

 Greene reported this shiner as ranging in the Mississippi River below 

 Iowa and Wisconsin and from southern Ohio to the Rio Grande. It 

 has been collected from the Mississippi River just above the Iowa line. 



NORTHERN BLACKNOSE SHINER 



Notropis heterolepis hcterolepis Eigenmann and Eigenmann 



The northern blacknose shiner is a rather slender minnow with a 

 lateral band running over the snout. The dark borders of the lateral- 

 line pores are expanded to form prominent crescent-shaped black 

 crossbars. The mouth is somewhat oblique but not as much so as in
