1. On a NEW GENUS AND SPECIES OF TROCHILIDZ FROM 
Ecuapor. By Joun Goutp, F.R.S. erc. 
The remarkably fine species of Humming Bird which I am 
about to describe, I have lately received from Ecuador. This new 
bird is remarkable for its large size, deeply forked tail and the har- 
monious hues of its plumage, which, although less glittering and 
metallic than in many other species, is nevertheless strikingly beauti- 
ful. I consider this bird to be new to science, both generically and 
specifically, and as the name of Victoria regia has been given to one 
of the finest flowers of the same part of South America, I am desirous 
of dedicating this new Humming Bird to the Empress of the French, 
and I accordingly propose to name it Hugenia imperatrix. Its native 
habitat is the vast Andean forests in the neighbourhood of Quito in 
Ecuador, where it procures its insect food from the bell-shaped flowers 
of the Dature.
