ashy-white, that of the fore and hind limbs darker ; hands and 
feet blackish, hair on the former short, on the latter long and 
silky ; base of the tail like the back in some specimens, creamy or 
ashy for about one-fourth of its length, gradually becoming darker 
until almost black at the tip ; all the under surface from the chin, 
underside of the limbs, and parachute white. Ears rounded, 
about half as long again as wide, clothed with long hair on the

extends to about half-way below the knee-joint, and is not very

body and the hind legs, shortest on the under side on the belly.
