1873.] THE BIRDS OF EASTERN PERU. 253 



The accompanying map (Plate XXV.), prepared mainly from Mr. 

 Bartlett's information, will serve to show more exactly the extent 

 of this district, and the situation of the various towns and villages 

 where collections have been made. 



Mr. Bartlett has kindly supplied us with the subjoined general 

 account of his expedition : — "I left 'England in January 1865, for 

 the purpose of exploring and examining the ornithological fauna of 

 Eastern Peru, and returned in February 1869. The route taken was 

 from Liverpool by a small schooner bound to Para, thence by steamer 

 up the Amazons, calling at many of the towns on the upper river, as 

 far as Tabatinga, thence by the Peruvian steamer to Nauta on the 

 Maraiion of the Peruvians. Nauta is one of the first settlements 

 made by traders on this side of the Andes. I remained in that town 

 about a month, during which time I occupied myself by collecting 

 the few birds and other things marked from that locality. At the 

 end of the rainy season, I prepared for a long and tedious journey up 

 the Ucayali. I started in May, and proceded in canoes accompanied 

 by Cucuma Indians of Nauta. The journey occupied a little over 

 four months. I formed the greater part of my first collections on 

 the banks of the river as I proceeded, staying at some of the 

 Cucuma and wild Conibo Indians' houses or Tambos, which afforded 

 me an opportunity of obtaining some of the forest mammals, birds, 

 and other objects. At Sarayacu I remained some time, and then 

 went on to Cashiboya, a town named after the wild Cashibo Indians. 

 It was at Sarayacu and Cashiboya that I procured a large number 

 of most interesting birds. Towards the end of August I returned to 

 Nauta, as I became anxious concerning the safety of the large collec- 

 tion already formed, knowing the danger of travelling down rapid 

 streams with canoes heavily laden. I arrived at the mouth of the 

 Ucayali about the 16th of September, and safely landed in Nauta on 

 the same night, when I prepared the collections to forward to 

 England. In reference to these collections see * Proc. Zool. Soc' 

 1866, p. 176. This done, I remained at Nauta collecting from 

 the surrounding country till February 1866, when I left on board 

 the Peruvian steamer for Yurimaguas, that being the furthest 

 accessible port on the Upper Huallaga. There I remained about 

 two months, waiting for the appearance of the dry season to com- 

 mence my excursions through Mission Alto, or Alto Amazonas, which 

 it would have been almost impossible to undertake during the rainy 

 season. I started in a canoe up the Paranapura river, and succeeded 

 in reaching the desired spot in a few days. Many canoes are from 

 twenty to thirty days going the same distance at the time that the
