CHARACTERS.--MALE.--Larger than _P. satanas_; black, with a
reddish-chestnut patch on the back, with a coarse brownish beard, longer
than in _P. satanas_; tail very thick, bushy.
FEMALE.--Similar to the male, but without the beard.
DISTRIBUTION.--Amazonia, Rio Negro, and Rio Branco; Upper Orinoco; British
Guiana.
HABITS.--This species is said to be solitary, or to go about only in pairs.
It derives its scientific name from its habit of drinking by lifting the
water to its head with its hands, instead of stooping down and applying its
mouth to the water. It is difficult to tame, being fierce and
ill-dispositioned.
