 Characters.— Male. — Larger than P. satanas ; black, with a 

 reddish-chestnut patch on the back, with a coarse brownish 

 beard, longer than in F. 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. 



HaMts. — 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.
