934 MR. R. I. POCOCK ON THE FEET 
T. thibetanus, but this naked area is not sharply defined behind 
by a coating of thick hair, but passes insensibly into the skin of 
the posterior surface of the leg, which inferiorly is scantily 
clothed with short hairs. The sole of the hind foot is entirely 
naked, the posterior limit of the plantar pad being marked by 
a transverse groove, which expands into a shallow depression on 
the hallucal or inner side.

Melursus ursinus. 
C. Left hind foot (too narrow for its length). D. Left fore foot. 
1 and 5, first and fifth digits; Cp., carpal pad. 
Feet of other Species of Bears. 
The feet of the Polar Bear and of the Sloth Bear are unique 
in the family, but those of other species, of which I have only 
seen dried skins or living specimens, agree in the main with those 
either of 7. thibetanus or of U. americanus, U. arctos and 
horribilis falling into the same category as U. americanus and 
Helarctos malayanus, and 7’. ornatus into that of 7’. thibetanus.
