1880.] ON NEW BIRDS FROM ECUADOR. 155 



4. On new Birds collected by Mr. C. Buckley in Eastern 

 Ecuador. By P. L. Sclater, F.E.S., and O. Salvin, 

 E.R.S. 



[Eeceived March 2, 1880.] 

 (Plates XVI., XVII.) 



Mr. Clarence Buckley has just returned from Ecuador, after four 

 years' absence, and, besides several collections transmitted during his 

 stay, has brought back with him one of the finest series of bird- 

 skins which we have ever had the pleasure of looking through. The 

 greater part of it was formed on the upper branches of the Rio Pas- 

 taza, and on the spurs lying between this stream and its affluent 

 the Bobonaza, Mr. Buckley's headquarters having been during the 

 greater part of the time the vdlage of Sarayacu on the latter stream, 

 which must be carefully distinguished from the place of the same 

 name on the Ucayali. Mr. Buckley's collection consists of upward 

 of 10,000 skins referable to nearly 800 species. Of these a complete 

 set has been secured for the collection of Salvin and Godman. Be- 

 sides the novelties which we proceed to describe, the collection 

 contains examples of many rare and little-known species, such as 

 Cotinga porphyrolcema, Scl. et Dev., ChamcBsa nobilis, Gould, Phlo- 

 gopsis erythroptera (Gould), Pipreola sclateri (Corn.), Osculatia 

 sapphirina, Bp., Mitua salvini, Reinh., Accipiter pectoralis, Scl., 

 and Leucopternis plumbea, Salvin. At a later period we hope to be 

 able to give a complete account of Mr. Buckley's collections in this 

 district.
