Mr. J. Gould on new Species of Humming-Birds. 307 
AMAZILIA ALTICOLA, Gould. 
Crown of the head and nape of the neck dark brown, with very 
slight reflexions of golden-green ; back of the neck, back, and ramp 
golden- or orange-green ; upper part of the throat, cheeks, and sides 
of the neck light golden-green ; lower part of the throat, chest, 
centre of the abdomen, thighs, and the thickly clothed tarsi pure 
white ; flanks rich bright buff ; under tail-coverts white, washed with 
buff ; tail rich deep reddish-buff, the two centre feathers washed with 
bronzy-grey, and the four outer ones, on each side, washed on their 
outer edges with bronzy-green ; wings purplish-brown ; bill black at 
the tip, the remainder white or flesh-colour. 
Total length 4 inches ; bill 13; wing 23; tail 13. 
Hab. Said to be the Puna district of Peru. 
Remark.—In its general style of colouring, this bird is very simi- 
lar to Amazilia leucophea, but, compared with that species, is a 
giant in size; it has also less of the glittering golden-green on the 
cheeks and sides of the neck. 
I am indebted to M. Bourcier for permission to describe this 
species. 
PHLOGOPHILUS HEMILEUCURUS, Gould. 
Crown of the head brownish-green ; back of the neck, upper sur- 
face, two middle tail-feathers, and the flanks grass-green ; sides of 
the face and ear-coverts greenish-brown ; centre of the throat, chest, 
middle of the abdomen, and under tail-coverts white ; tail rounded ; 
the four lateral feathers on each side white with an oblique band of 
black or blackish-purple occupying the centre of each, this band of 
black extending along the margin of the two outer feathers to the 
tip, so that the inner web only is white ; not so on the next, which is 
terminated with a large spot or tip of white ; upper mandible black ; 
under mandible fiesh-colour ; feet yellow. 
Total length 33 inches ; bill 3; wing 2}; tail 14. 
Hab. The borders of the Rio Napo. 
Remark.—I have no doubt that the bird from which the above 
description was taken is immature; when the adult is discovered, it 
will probably be found to be a very remarkable species ; in fact, the 
specimen described exhibits characters differing from those of every 
other known Humming-bird, among which its singularly-marked, 
rounded tail is especially noticeable. 
CALLIPHLOX ? IRIDESCENS, Gould. 
The whole of the body, including the upper and under tail-coverts, 
iridescent, pale green and light coppery-red, most brilliant on the 
throat ; the deeply forked tail steely dark-brown, each feather tipped 
with a more bronzy or purplish hue, which is seen only in certain 
lights; upper mandible and the tip of the lower one black, the 
remainder of the latter apparently reddish flesh-colour. 
Total length 3} inches; bill ? ; wing 1,%; tail 1}. 
Hab. Rio de Janeiro. 
Remark.—If, as I believe, I am right in referring this little bird
