These apes are not docile, and, notwithstanding their comparatively 

 large foreheads, they are far beneath the capuchin apes in intelli- 

 gence. AVhen they feel well, they purr like a cat ; when frightened, 

 they utter a sharp, shrill, palatal sound ; if angry, they scream like a 

 magpie. They were usually brought to me from the sea-shore, where 

 they used to sport in the most lively manner among the awarra palms, 

 never seeming to mind the long, sharp thorns with which these trees 

 are covered. The Indians shoot the mothers while they are carrying 

 the young on their backs, or else they shake the young from the trees 

 after the mothers have set them down. Males are rarely taken, but 

 nearly all that are caught are females, 



I had at several times specimens of another pretty ape, the mana- 

 Jcu {Pithecia leucocephala), called by the French maman dinan, and 

 aright by the Caribs. It is not larger than the squirrel-ape, but seems 

 to be twice as thick, on account of its long hair. The male is dark- 

 gray and covered with long hair, with a hairy and bushy tail about 

 ten inches long. The light-yellowish, hairy face looks like a mask, 

 beneath which the black nose and the mouth are strongly marked. 

 The female is brownish. This monkey is easily tamed, but is always 

 shy and melancholy. It lives in troops of not more than ten mem- 

 bers, in the deep woods. It is quite rare. 



These eight monkeys are the only species that live in Dutch Gui- 

 ana, no others being known, even to the Indians. Such broad streams 

 as the Amazon, Orinoco, and Rio Negro seem to make a separation 

 between species, so that mammalia, even when the plant-life is alike 

 on both sides, are wanting on one side of the waters while they are 

 common on the other side. — Translated for the Popular Science 

 Monthly from Das Ausland.
