is sharply circumseribed behind by the dense clothing of hair 
covering the lower side of the leg. 
The hind foot broadly resembles that of UJ. americanus, except 
that the depression behind the digital pads is clothed with hairs 
in the same way as the fore feet and the hairs from the inner 
edge do not encroach upon the sole in the depression marking off 
the plantar pad postero-internally. The tips of the pads of the 
first and fifth digits slightly overlap the proximal ends of those 
of the second and fourth respectively.

The feet differ from those of all other species of Ursidee, in 
that the digital pads are fused almost to their distal ends, 
so that no hair projects between them from the sides of the 
digits, and the first and fifth digits are set far forwards as 
compared, at all events, with 7’, thibetanus. Moreover, the 
depression behind the the digital pads is quite naked, as Gray 
pointed out. In the fore feet the carpal area is naked, as in
