HABITS. 
The specimen from which our description of this Marmot was drawn up, 
was found by us among the skins sent to England by Drummond and 
Douglas, procured by those gentlemen in our northwestern territories, 
and placed in the museum of the Zoological Society of London. Since we 
described it, the skin has been stuffed- and set up. 
Jvot a line was written in regard to its habits or the place where it was 
killed ; its form and claws, however, indicate that like the other species of 
Marmot found in America, it is a burrowing animal, and feeds on seeds, 
roots, and grasses. W e may also presume it has four or five young at a 
birth. 
GEOGRAPHICAL DISTRIBUTION. 
As just stated, the exact locality in which this animal was captured has 
not been given, but judging from the route travelled over by Douglas, we 
presume it was obtained in the mountainous districts that extend north 
and south between Western Texas and California, where it probably 
exists, but if seen has been supposed by the hunters and miners to be the 
common Marmot or woodchuck of the Atlantic States (A. monax). 
GENERAL REMARKS. 
This species differs from the young of Arctomys monax , by some 
naturalists named A. empetra, as we ascertained by comparing it with 
several specimens of that so-called species, in the museum of the 
Zoological Society, its feet being yellow instead of black, as in those 
specimens, and the belly yellow, not deep rusty red. Besides, the hairs
