Sp. Cu.—Body from 9 to 11 inches long; tail usually about an inch longer. Hind feet, 2.40 to 2.70 inches long. Skull 
about 2.50. Of largest size in the north. 
Gray vartety.—Above, grizzled light yellowish gray; beneath, pure white. A yellowish brown wash of greater or less 
extent on the back, and separating the colors of the belly and sides. Back of ears and adjacent region of the occiput usually 
with a white woolly tuft. 
Dusky varieTy.—Varies from pure jet black everywhere, through annulations on both surfaces of body, to a grizzled grey 
above, with the belly white, and only an occasional patch, especially on the throat, yellowish or brownish, annulated. 
Tail longer than the body. Ears very high, narrow, and acute, with sparse short hairs on 
the exterior surface or concavity ; internally, on their margins and tip they are coated with 
short brownish hairs which scarcely project beyond the margins of the ears. The base and 
middle portion, however, of the ear is coated with a dense bunch of whitish woolly fur, forming 
avery conspicuous mark. The tail is longer than the body, not bushy, but flattened. The 
feet are quite large, and the claws strong and much curved. The thumb is a rudimentary cal- 
losity, with a broad, flat nail; the fourth finger is very slightly longer than the third; the fifth 
or outer but little shorter than the second, each reaching to the base of the claw of the adjacent 
toe. The palms are naked. On the hind foot the third and fourth toes and claws are equal 
and longest; the second but little shorter; the fifth reaches to the base of the claw of the 
fourth, and the first barely to the base of the claw of the fifth. The soles are partly naked 
beneath the metatarsals; the exterior half, however, rather thickly covered with short hairs, 
which are still more sparse everywhere else, even under the toes, except on the tubercles, which 
are naked. 
The whiskers are longer than the head. The fore legs have long whisker-like hairs projecting 
far beyond the fur ; similar hairs are visible on the belly. 
The upper parts and sides generally are of a light ash gray, mixed with black and light 
brown. The dorsal surface from head to tail, a saddle mark across the back behind the fore
