68 QUADRUPEDS OF MASSACHUSETTS. 



Description. The under part of the head and front of the fore 

 limbs are reddish-brown, like the back ; the insides of the thighs 

 are colored like the belly, and on each side, or on the flanks, 

 there is a blackish line ; the tail is of a reddish-brown color above ; 

 mystachial bristles long and black. It resembles the common 

 Red Squirrel, or Sciurus vulgaris, of Europe, more than any spe- 

 cies which we have. The range of the species is much farther 

 to the north than either of the preceding. They are subject to 

 a disease of the incisive teeth, in the progress of which they grow 

 to an excessive length. All the Rodentia appear also subject to 

 the same misfortune.
