of the Marmots of North America. 58? 



belly cinereous at the root, black in the middle, whitish at 

 the tip, so that the animal has a hoary appearance ; tail 

 black, mixed with rust colour. Legs black ; c/a<cs dusky. 



The above description is copied from the History of Quadru- 

 peds. Our knowledge of this species is derived solely from the 

 description of Pennant, which he made from a specimen in the 

 Leverian Museum, and of which no figure was taken. The spe- 

 cimen was supposed to have come from the northern parts of 

 North America. I have in vain endeavoured to trace the spe- 

 cimen ; it was probably sold when the Leverian Museum was 

 dispersed by sale, but I have not been able to ascertain by whom 

 it was purchased. 



The Quadruped* which was described by Mr. Pennant under 

 the name of Tail-less Marmot, and called Arctomys Iludsonius by 

 Turton, has been considered by Dr. Shaw to belong to the ge- 

 nus Hyrav; it certainly is not an Arctomys. Nothing more is 

 known of the animal than that the specimen of it described by 

 Pennant and figured by Bewick was in the Leverian Museum.
