other quarters. In the large series of bird-skins collected by Mr. C. Buckley in Eastern Ecuador, 

 of which Mr. Salvin and I gave some account in the ' Proceedings ' of the Zoological Society for 

 March last*, were two examples of the present Puff-bird. These skins differ but slightly from 

 the typical specimen, principally in having the head and upper back of a considerably darker 

 hue. But the same difference is shown even more strongly in a specimen obtained by Mr. Buckley 

 at Tilotilo, in the province of Yungas, in Bolivia ; and I do not hesitate to refer both the Bolivian 

 and Ecuadorian skins to Bucco striolatus of Von Pelzeln. 



In its upper plumage generally B. striolatus closely resembles B. chacuru, and is of the same 

 type of structure. But it may be readily distinguished by the long lineiform striolations on the 

 lower surface, as well as by the dark bill.
