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 rump 

 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 if; wing 2-f; tail If. 



Hab. Said to be the Puna district of Peru. 



Remark. — In its general style of colouring, this bird is very simi- 

 lar to Amazilia leucophcea, 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 flesh-colour ; feet yellow. 



Total length 3£ inches ; bill f ; wing 2-^ ; tail 1^. 



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 1 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 f ; wing 1 T ^> ; tail lj. 



Hab. Rio de Janeiro. 



Remark. — If, as I believe, I am right in referring this little bird
