Arctomys monax, Linn. 



Woodchuck, Ground-hog. 

 Arctomys emj^eti^a, (Sabine) Rich. 

 Arctomys pruinosus, Gmelin. 

 A-kwa-hwa-chis. Saulteanx. 

 Nova Scotia and New Brunswick and westward around the- 

 shores of Hudson's Bay to the Mackenzie and Liard Rivers^ 

 as far north as Lat. 62*^. 



Arctomys caligatus, Eschscholtz. 

 Hoary Marmot. 



Arctomys j^^'^'^^osus, (Gmel.) Rich. 



Arctomys Okanaganus, King. 

 Rocky Mountains westward to the Cascade Range and 

 nortliward to the Arctic Circle. Often seen among heaps of 

 angular masses of 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 

 jrruinosus. 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 Ginelin'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 Ba}', 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. Tnonax j and 

 although the A. pruinosiis of Richardson is undoubtedly the 

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

 ing been formerly applied to a difierent species.
