Distribution. Paraguay. 



Habits. This rare Capuchin lives, as Azara relates, in the 

 forests of Paraguay, and is met with both in single couples and 

 in small troops. They are very lively little animals, ever in 

 motion, swinging themselves from tree to tree by means of 

 their tails, the mothers of the company generally carrying 

 their single young one on their back. When once tamed they 

 become very affectionate ; when angry they can give vent to 

 excruciating screams. Their ordinary voice resembles that of 

 someone laughing with all their might, and crying Hu ! hu ! 

 hu! 



Only once has a specimen of this Capuchin been an inmate 

 of the Zoological Gardens in London.

THE WOOLLY MONKEYS. GENUS LAGOTHRIX.

 distinguished by having a heavy body, and a rounded head, 

 with the muzzle much flattened, and the nostrils nearly circular, 

 but not approximated. More conspicuous than any other ex- 

 ternal character is the woolliness of their under-fur. 



The name Lagothrix was given by Humboldt to the first 

 specimen he found, because of the similarity of its fur to that
