the fourteen years he had traded he never found this species in any 

 other locality. On my return from the 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 determined to spend a 

 few months in the mountain country, I passed up the Maranon and 

 Huallaga to Yurimaguas, and so on to Xiberos, whence I went to the 

 town of *Chyavetos in the mountains. Having heard that this large 

 Monkey was to be met with in this little known locality, I remained 

 at Chyavetos about two months; and during that time I became well 

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

 (called in the Inca language Urcu Maci-suppah or Quillu Maci- 

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

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

 forest foot road, 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 Indians brought down 

 another with the poison dart. Having obtained two of them, I felt 

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

 ever, 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 my second specimen. Of 

 course I was obliged to keep peace for we had not tasted meat for 

 several days before starting from Chyavetos, 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. 



"These Monkeys appear to go in small parties, passing through 

 the forest at a rapid pace, feeding on different kinds of berries. The 

 berries I found in the mouth and stomach of the male were similar to 

 the gooseberry in external appearance; they have, however, a large 

 stone inside. These stones appear to pass through them, as I found 

 several in the intestines. 



"On my return to town I found an Indian who had arrived from 

 Cauhapanas, a small town lying at the foot of the mountains in the 

 Maranon Valley, north west of the town of Chyavetos, who had in 

 his possession a very fine young Spider Monkey, which proved to be
