Most of its fur is gray, but the shoulder areas are reddish gray, and the ventral fur is pure white or creamy white.

There is also a ring of black fur surrounding each eye.

The dorsal surface of the tail is gray for the first one third to one half of its length (going from the base to the tip); the remainder of the dorsal surface of the tail is white.

The tail is hairless except for about its first ten mm (going from the base to the tip).
