A friend of mine, an ardent angler, returned 

 recently from Cape Nome and the Yukon, in 

 Alaska, where he resided for several years. He 

 informed me that the grayling is very abundant 

 in the streams of that region, and that he had 

 taken thousands on the fly; but not knowing 

 that they differed from the Montana grayling, he 

 did not examine them closely. 



THE MICHIGAN GRAYLING 



(^Thyjiialhts tricolor) 



The Michigan grayling was first described by 

 Professor E. D. Cope, in 1865, from specimens 

 from the Au Sable River. He named it tricolor, 

 on account of its handsomely-decorated fins and 

 body. At that time it was abundant in the Au 

 Sable, Manistee, Marquette, Jordan, Pigeon, and 

 other rivers in the northern part of the lower pen- 

 insula of Michigan, and in Otter Creek, near 

 Keweenah, in the upper peninsula. It has a some- 

 what larger head than the Arctic form, its length 

 being about one-fifth of the length of the body ; 

 the outline of the latter does not differ except 

 in not being so prominent over the shoulder.
