This specimen is evidently much faded, but it still retains the trace of darker- 
coloured points to the hairs, although the general colour has become almost a uniform 
yellowish fawn. The area behind the moustache and below the eye, a spot above the 
eye, between the eye and the ear and behind the latter, and also a small area external 
to the base of the tail are nearly white. The under parts are pure white. The tail 
is brownish on its distal two-thirds and rufous brown towards the tip.
