Mr. J. Gould on new Species of Humming-Birds. 309 
apex by a broad band of steel- or bluish-black ; abdomen green ; 
wings purplish-brown ; bill black. 
Total length 3} inches ; bill ; wing 22; tail 13. 
Hab. Ecuador. 
Remark.—tThis species is nearly allied to Schistes Geoffroyi ; but 
it is a much finer bird, the forehead and throat being covered by a 
mask of glittering green ; its bill is also considerably longer. 
- Tuaturanta Tscuuptt, Gould. 
Crown of the head and all the upper surface golden-green, in- 
clining to bronzy-green on the tail-coverts ; throat beautiful green ; 
abdomen prussian-blue ; under tail-coverts steel-black, many of the 
feathers slightly fringed with white ; thighs, tarsi, and anal region 
white ; tail steel-black. 
Total length 41 inches ; bill 1 ; wing 21; tail 12. 
Hab. The neighbourhood of the River Ucayali, and the countries 
of Ecuador and Peru. 
Remark.—The two species to which this bird is most nearly allied 
are the 7. furcata and T. nigrofasciata; but it differs from the 
former in having a more robust body and broader tail-feathers, and 
in having the abdomen prussian-blue instead of ultramarine-blue ; 
and from the latter in the form of the green mark on the throat, 
which in this bird is truncate, while in 7’. nigrofasciata it descends 
nearly to a point towards the centre of the abdomen. This is the 
species mentioned by Tschudi in his ‘Fauna Peruana,’ under the 
name of Trochilus furcatus,—a fact of which I am certain, as I have 
received a specimen from his collection direct from Neuchatel. 
OreEopyra Levucaspis, Gould. 
Crown of the head exceedingly beautiful glittering grass-green ; 
back of the neck, and all the upper surface, deep grass-green, with 
bronzy reflexions ; throat pure white, contrasting conspicuously with 
the glittering grass-green of the breast ; flanks and abdomen greyish- 
n, with bronzy reflexions; wings purplish-brown; tail forked 
and steel-black ; thighs thickly clothed with hoary or greyish-brown 
feathers ; behind the eye, and extending some distance down the 
sides of the neck, is a stripe of pure white; bill straight, and both 
mandibles of a uniform black. 
Total length 44 inches ; bill 13; wing 21}; tail 14. 
_ Hab. The Volcano of Chiriqui in Costa Rica, where it was 
discovered by M. Warszewicz at an elevation of from 9000 to 10,000 
feet. 
Remark.—One solitary individual, and that badly shot about the 
tail, is the only example I have ever seen of this remarkable and 
beautiful bird—a bird which differs so much from every other mem- 
ber of the Trochilide, that I have been necessitated to make it the 
type of a new genus.
