34 ATELEUS 



of this species. It was nearly black, but just showing the light golden 

 hair coming on the under side of the body and tail, some few white 

 hairs on the cheeks, and slight golden crest, sufficient to identify the 

 species. I bought it of the Indian, and managed to bring it alive to 

 Yurimaguas, where it died. 



"On my arrival I was informed by some of my old Indians, that 

 they discovered this Monkey during my absence on the Upper Hual- 

 laga, (on the south eastern shore). One of the Indians said that he 

 brought three young ones alive, which died soon after his arrival in the 

 town. I here give an idea of the great range this Monkey inhabits, 

 owing to the ease with which a beast that can use his long arms and tail 

 may travel a country of this description. It is found on both sides of 

 the Peruvian Amazon (or Marahon), 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 common in the 

 dense forest on the hills near the latter town, their range running 

 between the Huallaga River and Ucayali River to the head waters 

 of the Huallaga, between the towns of Lamas and Sarayaqu. Here 

 they occupy the interior forest, and appear to be common, according to 

 accounts given me by Indians of that country — as also on the lower 

 spurs of the mountains between the towns of Moyabamba and the 

 Huallaga River. 



"Then again on the Rio Tigri, north western shores of the Great 

 Maranon, there is not the slightest doubt that this species is to be 

 found ranging along the lower spurs of the Andes, across Ecuador and 

 Colombia, over the head waters of the Rio Napo, Rio Japuri, and Rio 

 Negro, where Natterer first discovered it."
