more extensive upon tlic tail-feathers than on those of the 

 male ; but this appears to be characteristic of the females of 

 all the various species of the genus Bourcieriu. 



The present species is one of the very handsomest of this 

 genus, being only exceeded in beauty by B. inca, Gould.

This bird was first described by Bourcier in the ' Revue 

 Zoologique '' for April 1843, from New Granada ; and in the 

 same year Tschudi described and figured it from Peru as T. 

 otero. Succeeding authors have kept these birds separate, 

 notably Mr. Gould, founding the species upon the size, chiefly 

 that of the bill. In his ' Introduction ' to the Trochilidai, 

 Mr. Gould further distinguishes the bird from Venezuela as 

 Leadbeatera splendens, stating that it is allied to the Bolivian 

 bird, but differs in having a " straighter and shorter bill, and 

 in the green tint of the under surface.^^ Lately Mr. Buckley 

 has brought specimens from Chairo, in Bolivia, a place about 

 6000 feet above the sea ; and these are not to be distiugviished 

 from the Columbian bird. Tschudi's type of Trochilus otero is 

 quite a young bird, and in length of bill and general size is 

 like specimens from Columbia; while the Venezuelan birds, 

 L. splendens, and adult so-called otero, from Bolivia, with the 

 long bills, are, so far as I am able to see, precisely alike ; and 

 intermediate lengths of bill arc obtainable in specimens from
