THE HOWLERS. J 97 



Distribution. — This is the species of Howler which ranges 

 furthest to the south. It occurs most abundantly in Southern 

 Brazil, Paraguay, and Bolivia, but Mr. Bates records his having 

 obtained a specimen at Villa Nova, on the Upper Amazons, 

 which had come from above Borba, on the Rio Madeira. 

 He did not, however, meet with it on any other part of the 

 Amazon region. Mr. Graham Kerr saw it in troops on the 

 banks of the Pilcomayo river. 



Habits. — Like nearly all the Howlers, the present species is 

 of a sulky disposition, in captivity slinking away out of sight 

 when approached. The members of this genus are the only 

 Monkeys which the Indians have not succeeded in taming. 

 They rarely survive their captivity many weeks
