river, a southern confluent of the Orinoco ; Venezuela. ‘“ This 
species is found on both sides of the Peruvian Amazon 
(or Marafion), on both shores of the Huallaga, and in the 
interior forest near the town of Chamicuros. I was told 
by some of the oldest Indians that these animals are com- 
mon in the dense forest on the hills near the latter town, 
their range extending between the Huallaga river and Ucayali 
river to the head-waters of the Huallaga, between the towns of

and over the head-waters of the Rio Napo, Rio 
Japura and Rio Negro, where Natterer first discovered it.”
