DESCRIPTIONS 
Or 
THREE NEW SPECIES OF HUMMING-BIRDS 
By JOHN GOULD, Esa., F.R.S., &e. 

My pear Sir WittiamM—I send you herewith, descriptions of 
the three new Humming-Birds lately sent by our mutual corres- 
pondent, Professor Jameson of Quito, who will, I am sure, be much 
pratified to find that his researches haye been rewarded with the dis- 
covery of several additional species of a group of birds, the beauty 
of which has attracted the attention of so many explorers, as to 
render the acquisition.of even one novelty a source of gratulation. 
Ever truly yours, 
JOHN GOULD.
