 Rocky Mountains westward to the Cascade Range and' 

 northward to the Arctic Circle. Often seen among lieaps of 

 angular masses ot loose rock. I can find no reference to its 

 being found east of the Rocky Mountains. 



The specific name caligatus has here been used instead of 

 jyruinosus. which latter name, as was pointed out to me by Prof» 

 Macoun, appears to have been in all probability first applied 

 to a light-colored specimen of monax. Pennant's description 

 on which Gmelin's name pruinosus was founded, as given in 

 Coues and Allen's " Monographs of North American Rodentia " 

 p. 926, agrees so well with a specimen of A. monax from 

 Hudson's Bay, the original locality, now in the Geological and 

 Natural History Museum, that I have very little hesitation in 

 placing Gmelin's species as a synonym of A. raonax i and 

 although the A. pruinosus of Richardson is undoubtedly the 

 true A. caligatus., his name cannot stand on account of its hav- 

 ing been formerly applied to a different species.
