4. List of Birds collected at Pebas^ Upper Amazons, by Mr. 

 John Hauxwell, with Notes and Descriptions of New 

 Species. By P. L. Sclateh, M.A., Ph.D., F.E.S., and 

 OsBERT Salvin, M.A., F.Z.S. 



(Plate XLV.) 



After several years of inaction as regards zoological pursuits, ]\Ir. 

 Hauxvvell has again transmitted to this country one of his beautifully 

 prepared series of bird-skins from the Up[)er Amazons. Having been 

 recently engaged on Mr. Bartlett's collections from the same neigh- 

 bourhood, it has been of great interest to us to examine Mr. Haux- 

 well's series, which embraces examples of 135 species. These are 

 all from the vicinity of Pebas, a town situated on the north bank of 

 the main Amazons, some way below the mouth of the Napo. Four 

 of them appear to be new to science, namely Oryzoborus melas, 

 Tyranniscus gracilipes, Percnostola fortis, and P or z ana fascial a. 



The following is a complete list of the species, the nomenclature 

 adopted, where no additional reference is given, being that of Sclater's 

 ' American Catalogue,' except in the case of the Trochilidce, which 

 have been determined by Mr. Gould, and are named according to 

 the catalogue in the Introduction to his Monograph of that family : —
