(Plate XIII.) 



During my recent four years' sojourn on the Upper Amazous I 

 met with the following species of Monkeys : — 



1. Ateles variegatus, "Wagner (A. bartletti, Gray, P. Z. S. 

 1867, p. 922, pi. xlvii.). Variegated Spider Monkey. 



On my arrival in Peru in 1865 Mr. Hauxwell told me of the ex- 

 istence of a large species of Ateles, which he had killed hut failed to 

 preserve. He told me that he met with it on the Rio Tigri, a small 

 tributary that runs into the Amazons about four miles above the 

 town of Nauta, on the north-western shores of the Peruvian Amazon. 

 He said that during the fourteen years he had traded he never found 

 this species in any other locality. On my return from the River 

 Ucayali, in September 1865, I wished to ascend the Rio Tigri in 

 pursuit of this Monkey, but was obliged to abandon the idea on 

 account of the prevalence of fever and ague at that season ; and, 

 moreover, the Indians were unwilling to join me in so dangerous a 

 country. Having then determined to spend some few months in the 

 mountain-country, I passed up the Maranon and Huallaga to Yuri- 

 maguas, and so on to Xeberos, whence I went on to the town of 

 Chyavitos, in the mountains. Having heard that this large Monkey 

 was to be met with in this little-known locality, I remained at Chy- 

 avitos about two months ; and during that time I became well ac- 

 quainted with the Indians, who informed me that a long-armed Ape 

 (called in the Inca language TJrcu Maci-suppah, or Quillu Maci- 

 suppah) was to be met with at a distance of three or more days' 

 journey. I engaged three active Indians, and started by way of a 

 forest footroad that had been opened by a Catholic priest to the 

 town of Moyabamba as part of his penitence. At the end of three 

 days I reached the highest point of the mountains ; here we came 

 across a number of the Monkeys in question — about eight or nine. I 

 shot the male that is now in the British Museum ; my Indian brought 

 down another with the poison-dart. Having obtained two of them, 

 I felt perfectly satisfied that I had discovered a new species. While, 

 however, I was busily engaged preparing the finest specimen, my 

 Indians had quietly placed the other on the fire ; to my great horror 

 and disgust they had singed the hair off, and thus spoiled mv second 

 specimen. Of course I was obliged to keep peace, for we had not 

 tasted meat for some days before starting from Chyavitos, and this 

 Monkey proved a very dainty dish to us all. 



I was still in hopes of obtaining more specimens in the Munga- 

 Urcu, or Saucepan Mountain (so called from its peculiar shape), 

 but in this, after much hard work, I failed.
