11. Catalogue of Birds collected by Mr. E. Bartlett on the 

 River Huallaga, Eastern Peru^ with Notes and Descrip-

(Plate XXXIV.) 



Mr. E. T. Higgins having kindly allowed us to examine Mr. E. 

 Bartlett' s second collection of birds from Eastern Peru before its 

 dispersal, we have the pleasure of submitting the following account 

 of it to the Society. 



The present collection was formed during the excursion spoken of 

 in the letter of which an extract is given in the Society's ' Proceed- 

 ings ' for January 1867*, and was mainly amassed at three locali- 

 ties — Yurimaguas, Xeberos, and Chyavetas. 



Yurimaguas is an Indian town on the Huallaga, about sixty miles 

 from its embouchure into the Amazon, mentioned in Herndon and 

 Gibbons's ' Exploration of the Amazon ' (p. 171)- 



Xeberos is an Indian village, about fifty miles north-west of Yu- 

 rimaguas, on a small river (the Aypena) which flows into the Amazon 

 just above the Huallaga. 



Chyavetas, or Chayavetas, is situated about seventy miles west of 

 Yurimaguas. 



All these three places are marked in the copy of the Spanish map 

 (of 1790) attached to Herndon's volume. 



The whole collection consists of nearly 1000 skins, referable to 

 205 species. Of these but very few are new to science, almost the 

 only noticeable exception being the new Chcetura described below. 

 This may probably arise from the fact that Mr. Hauxwell collected 

 largely at Chamicuros (a village situated upon the opposite bank of 

 the Huallaga, but in the same neighbourhood) in 1854, and that 

 his collections appear to have been widely dispersed in Europe. In 

 comparing the present collection with the former collection from 

 the Ucayali, we find only 94 species common to the two, while 112 

 species are in the Huallaga collection which had not been previously 

 obtained by Mr. Bartlett. 



The following is a list of the species of birds collected at the three
