Speciric cHars.—Head and body about 10.50; tail-vertebrae 8.50 to 9.00; 
tail to end of hairs about 11.50, rather longer than head and body.  Pelage soft 
and full. Above, including the head, clear dark gray; beneath, deep reddish- 
orange, which blends with the gray of the sides, and often extends high up on 
the sides at the shoulders, sometimes meeting on the back, where, however, it 
is generally more or less mixed with gray. Sides of the head and chin light 
gray. Tail tricolored below, centrally deep reddish-orange, then black, and 
white-edged ; upper surface mixed black and white. 
The color varies greatly in different individuals, but less so than in most 
of the other Mexican Squirrels, the chief variation being in the direction of 
melanism. The gray, however, varies from whitish-gray to dark iron-gray,
