CHARACTERS.--Fur short and woolly; face entirely naked; head longer than
broad; a well-marked swelling of the skull between the eyes; the upper
incisors sub-equal. Smaller and more robust than _P. diadema_, the head
longer, the hair on the limbs shorter, the tail longer.
{101}Body yellowish-white; a spot on the top of the head dark brown,
sometimes washed with rufous, separated from the face by a white frontal
bar. Face black; eyes brownish-yellow; interior of ears black, and naked; a
grey patch on the middle of the back; outer aspect of the fore-arms, and
hind-legs, ashy-grey; rest of the body white. Hands and feet white. Tail
yellowish-white. Length of body, 18 inches; of tail, 22 inches.
YOUNG.--Entirely white, with a dark brown spot on the head; the under
surface of the body washed with rufous.
VARIETIES.--Two well-marked varieties of this species are known, both of
which were for many years considered to be distinct species. Continued
exploration has, however, now resulted in the accumulation in various
museums of a large amount of material from many localities, and this proves
that the two forms really belong to but one species.
