On new Species of Birds from Western Ecuador. 493 
superseded by a clear grey, a process the progress of which 
I watched in a specimen which lived for many years in the 
Gardens of the Zoological Society. 
Mr. Sharpe also includes amongst the Buteoninse the genera 
Morphnus and Thrasaetus ; but as these appear to me to 
be, notwithstanding their scutellated tarsi, essentially Hawk 
Eagles, I defer their consideration until I reach that group. 
XLYI.— On some new Species of Birds from Western Ecuador. 
By Osbert Salvin, M.A., F.R.S., &c. 
(Plate XIY.) 
Mr. C. Buckley, who recently enriched Mr. Godman's and 
my collection by sending us a large series of bird-skins from 
Bolivia, is now collecting in Ecuador, having, on leaving 
Bolivia, paid a few months' visit to this country. During his 
absence from South America he instructed his native assistant, 
Seiior Yillagomez, whom he left at Guayaquil, to proceed to 
Puna Island and to make an excursion into the Province of 
Loxa in quest of butterflies and birds. On Mr. Buckley's 
return to Guayaquil from England, he found Villagomez had 
returned with collections; and he at once forwarded the birds 
to us through his agent, Mr. E. T. Higgins. 
The collection altogether contains specimens of 140 species 
of birds, many of which are of considerable interest, and some 
new to science. These last I now propose briefly to describe, 
reserving a more detailed account of the whole series to a 
future occasion, by which time I trust we shall receive other 
collections from Mr. Buckley, who, I understand, has now 
proceeded into the interior of Ecuador, and is working in some 
of the valleys of the eastern slope of the Andes.
