granti. The external and cranial differences between R. 

 granti and the various forms of the Woodland Caribou are 

 so great in almost every respect that no detailed comparison 

 is necessary. 



According to Mr. Stone, Rangifer granti inhabits the "bar- 

 ren land of Alaska Peninsula, ranging well up into the moun- 

 tains in summer, but descending to the lower levels in winter, 

 generally feeding on the low flat lands near the coast and in 

 the foothills. They formerly lived in considerable numbers 

 on Unga Island, where they are now practically extinct. 

 The only other island inhabited by them is Unimak Island, 

 at the western end of the Alaska Peninsula. They were 

 formerly exceedingly abundant, but they have been of late 

 greatly reduced in numbers through the agency of market 

 hunters." 



The habitat of R. granti is thus an isolated area occupying 

 the treeless portion of the Alaska Peninsula and (formerly at 

 least) some of the immediately adjoining islands at the 

 extreme western end of the peninsula.
