EryTHRONOTA? ELEGANS, Gould. 
Crown and all the under surface of the body glittering light-green ; 
back of the neck and back golden- or orange-green ; upper tail-coverts 
purplish-red or puce-colour ; tail long, forked, and of a purplish 
violet-hue with green reflexions on the tips of the two centre feathers ; 
wings purplish brown; tarsi white; under tail-coverts grey with 
ronzy-purple centres ; upper mandible flesh colour at the base, and 
black for the remainder of its length ; under mandible flesh colour, 
except at the tip, which is black. 
Total length 32 inches; bill 12; wing 21; tail 2. 
Hab. Unknown. 
Remark.—It is easier to assign a specific name to a bird than to 
determine to which generic form it is referable; and if there be any 
bird which is a puzzle to the brain of the ornithologist, this is one. 
It is a very elegant species, and quite distinct from every other known 
Humming Bird ; in its glittering light-green crown, throat, and chest 
it looks like a Chlorostilbon, but the form of its tail and some other 
characters ally it to the Hrythronote, with which I have provisionally 
placed it. 
THAUMATIAS VIRIDICEPS, Gould. 
Crown of the head, nape, and sides of the neck glittering light 
green; back and shoulders bronzy-green ; throat and abdomen pure 
white; flanks white, faintly spotted with yellowish-green ; under 
tail-coverts white ; the rather short and narrow tail-feathers purplish- 
grey, with an obscure band of purplish-brown near the tip of the 
three outer ones on each side; upper mandible black; under man- 
dible yellowish, except at the extreme tip, which is black. 
Total length 4 inches ; bill 52 ; wing 22; tail 13. 
Hab. Ecuador. 
Remark.—Of this somewhat remarkable species I have two speci- 
mens, which appear to be male and female. It is a robust bird, being 
almost as stout in its bill, head, and body as the members of the 
genus Cyanomyia, while its tail is short and the feathers narrow, as 
in Thaumatias leucogaster and T. chionopectus. 
THAUMATIAS CZRULEICEPs, Gould. 
Crown of the head and back of the neck deep shining greenish- 
blue ; back and shoulders green, passing into bronzy-green on the 
rump and upper tail-coverts ; tail nearly uniform bronze, with a very 
faint indication of a zone of brown across the outer feathers near the 
tip ; wings purplish brown; sides of the neck glittering bluish-green, 
the blue tint predominating on the ear and immediately under the 
eye ; centre of the throat and chest broken glittering green and white ; 
flanks bronzy-green ; under tail-coverts grey, with brown centres ; 
upper mandible dark brown; under mandible appears to have been 
yellow, except at the tip, which is dark brown. 
Total length 34 inches; bill Te; Wing 21; tail 1. 
Hab. Bogota.
