DESCRIPTION. 
[Extracted from Gopman’s Nat. Hist.] 
“‘ The body of the Maryland Marmot is about the size of that of a rabbit, and is covered 
by long, rusty-brown hair, generally gray at the tips; the face is of a pale, bluish ash-colour. 
The ears are short, but broad, and as if they had been cropped at their superior edges ; the 
tail is about half the length of the body, and is covered with dark-brown hairs, somewhat 
bushy at its extremity. The feet and claws are black; the claws are long and sharp.” 
Warden says that, in Vermont, the largest weigh eleven pounds; but that in the southern 
; 
states they attain a greater size.
