FAMILY CYPRINIDAE 1G3 



maxillaries. The scales of the first row above the lateral Ime have dark 

 bars which alternate with the black marks on the lateral-line scales, 

 producing a zigzag appearance. The scales are 5-36-3; 12 to 14 scales 

 are in front of the dorsal fin. The jaws are equal or nearly so, the 

 maxillary reaching the posterior nostril. The mouth is oblique, making 

 an angle of decidedly less than 60 degrees with the vertical. The 

 pharyngeal teeth vary from 4 — 4 to 1, 4 — 4, 1. This species reaches a 

 length of 2 1/2 inches. 



The blackchin shiner ranges through the glacial lake districts of 

 Ontario, Minnesota, Wisconsin, Michigan, Iowa, Illinois, Indiana, Ohio, 

 and New York. In Minnesota Woolman (1895) reported it from the 

 Pomme de Terre River at Appleton. It has been collected from many 

 places in the Mississippi drainage and from some of the small streams 

 of the Superior drainage. Greene (1935) reported this species to be 

 especially characteristic of lakes in Wisconsin. Collections at the Uni- 

 versity^ of Minnesota indicate that it is rare in streams but occurs occa- 

 sionally in lakes throughout the state. 



SOUTHWESTERN SAND SHINER 



Notropis deliciosus deliciosus (Girard) 



This fish has a stout body with a dusky lateral band and 7 anal rays. 

 There are 35 to 38 scales in the lateral line. The pharyngeal teeth are 

 4 — 4. This species reaches a length of 2 1/2 inches. 



The southwestern sand shiner ranges from the Dakotas through 

 Ilhnois and part of Indiana and southwest into Mexico and Texas. This 

 minnow was identified by Hubbs from a creek 16 miles east of Austin, 

 Minnesota. There are no specimens of this subspecies in the University 

 of Minnesota collections. 



NORTHERN SAND SHINER 



A^otropis deliciosus stramineus (Cope) 



This subspecies of Notropis deliciosus is the most common form found 

 in the Great Lakes area. It is found in streams throughout Minnesota 

 but is most common in the northern part. 



The northern sand shiner ranges from southern Ontario and Minne- 

 sota southward to Iowa and the Ohio Valley. Greene (1935) reported it 

 from the Mississippi and St. Croix rivers and from numerous streams 

 throughout Wisconsin, including the Lake Superior and Lake Michigan 

 drainages. 



TOPEKA SHINER 



Notropis topeka (Gilbert) 



This shiner has a stout body with a lateral band ending in a black 

 caudal spot. The scales are 5-35-6. It reaches a length of 3 3/5 inches.
