more extensive upon the 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 Bourcieria. 
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 
Banlosionias for April 1843, from New Granada; and in the 
same year Tschudi described and figured it ni Peru as 7. 
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 Trochilide, 
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 distinguished 
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 are obtainable in specimens from
