Range. — While Rangifer mcguirei breed in lim- 

 ited numbers in the vicinity of the type locality, 

 they represent but a small percentage of those 

 that appear from the north and northwest during 

 September and October. It is probable this 

 movement is an extension of the migration of 

 caribou which occurs in the region of Fairbanks; 

 but until there is positive evidence of this, the 

 range of mcguirei may be designated as the vi- 

 cinity of the Alaska-Yukon boundary from the 

 base of Mt. St. Elias northward.
