406 On a supposed new Species of Humming-bird. 
XLL-—O» a supposed new Species of Humming-bird from 
the Juan-Fernandez Group of Islands, By JOHN GOULD,

men of Santiago de Chile having stated that the fine red bird 
s p 
Chile, have, I believe, been collected in the most eastern of the 
islands during the last forty years. I therefore propose to 
give this green bird a specific appellation, and in calling it 
Eustephanus Leyboldi Y am only paying a just compliment 
to a gentleman in Santiago who is endeavouring by all the 
means in his power to set this vexed question at rest, and to 
ascertain whether there be one, two, three, or four species of 
Trochilide inhabiting that distant group of islands in the 
wide Pacific. 
Eustephanus Leyboldi 
has a glittering green crown, and is in many respects very 
similar to the bird usually called E. Stokes’, but differs in 
having a longer bill, and in the spots on the throat being 
bronzy and disposed in lines down that part of the under sur-, 
face and the flanks, as in Æ. galeritus, instead of being gene- 
rally dispersed over the throat and clustered on the face as 
in Æ, Stokesi; but the greatest difference between the two 
consists in the colouring of the tail-feathers, those of Æ. Stokest 
aving their outer webs green, and their inner ones wholly 
white, while in the present bird the outer webs and the basal 
portion of the inner ones are green, and only the apical portion 
of TA pue white. 
otal length 48 inches, bill 14, wing 22, tail 2, tarsi 8.
