the blnck mark on the hack of the neck more distinct, as 
well as the black and white flank bands ; the tail, more¬ 
over, is much less bushy. The top of the head, back of the 
neck and shoulders, and the front of the fore legs, are grey ; 
the hinder parts of the back are of a deeper hue, and are much 
suffused with yellowish brown; here the lmirs arc of a deep 
brown colour next the skin, and fulvous towards tho point; 
this is followed, on each hair, by a broad white space, and the 
tips of the hairs are black. In front of the eye is on oblong 
black patch, and immediately behind the eye, tho fur is also 
dark, but less so than in front; below this dark band thus

black, and a line of the same hue runs from this part along 
the back of the neck, and extends somewhat on to die back. 
The hinder part of the fore legs is sooty black, and a broad

tarsi are densely clothed with long black-brown hairs ; the 
upper surface of the foot, however, is usually suffused with

are short, and nearly conical; they scarcely project beyond

the toes. The basal half of the toil is well clothed, but by no 
means bushy, and the general colouring of this part is almost
