FAMILY CYPRINIDAE 165 



N. heterodon. The pharyngeal teeth are 4 — 4, those of the outer row 

 being absent. This minnow reaches a length of over two inches. 



This species ranges from Saskatchewan eastward through the Great 

 Lakes region to Maine and southward to Iowa. It is found in small 

 streams and lakes of northern Minnesota, including North Shore 

 streams of the Lake Superior drainage. Greene (1935) reported it from 

 the St. Croix River and from some of the Wisconsin tributaries of the 

 Mississippi River farther south. 



PUGNOSE SHINER 



Notropis anogenus Forbes 



This minnow has a rather stout body with a distinct lateral band and 

 a spot on the tail. There are 34 to 37 scales in the lateral line. The 

 pharyngeal teeth are 4 — 4. It reaches a length of 1 1/2 inches. The 

 mouth is very small and oblique. 



This species occurs in the glacial lake regions from eastern North 

 Dakota through Minnesota, Wisconsin, Michigan, northern Illinois, 

 Indiana, and Ohio, and into the St. Lawrence drainage of New York. 

 Cox (1897) reported it as probably rare in Minnesota and stated that 

 it had been taken in the Cedar River at Austin by Dr. Meek. Greene 

 (1935) reported it from the upper St. Croix River in Wisconsin. 

 Hankinson (1929) reported it from the Red River drainage. It prefers 

 and is found in the small streams of the Mississippi River and Lake 

 Superior drainages. There are no specimens in the University of Minne- 

 sota collections. 



GENUS Fhenacobhis Cope 



SUCKERMOUTH MINNOW 



Phenacohius mirahilis (Girard) 



This minnow has a distinctly suckerlike mouth with thick lips. The 

 cylindrical body is colored an olivaceous silver and has a black spot at 

 the base of the caudal fin. The scales are 6, 43-51, 5. The teeth are 4 — 4 

 and are generally hooked. 



This species ranges from South Dakota to western Ohio and south- 

 ward to Texas and Tennessee. It is apparently rare in Minnesota, for it 

 has been collected only from southeastern counties. Greene (1935) 

 reported it from the Mississippi River below La Crosse.
