Genus H e l ia n g e l u s , Gould.
("HAtoy, sol, et ayyeXos, angelus.)
Generic characters.
Male.—Bill straight, about the same length as the head, and cylindrical; wings somewhat powerful; tail
rather round in form and o f medium s iz e ; fe e t moderately str o n g ; hind toe and nail the same length as the middle
toe and n a il; gorget luminous, bounded below by a crescent o f white.
Female.— Destitute o f luminous colouring.
This is perhaps a better-defined genus than any other o f those into which the Andean groups o f Humming-
Birds have been divided. Its characteristics are a moderately long bill surmounted by a band o f lustrous colour
on the forehead, and a deep luminous gorget separated from the general colour o f the body by a semicircular band
of white. Like the Heliantheee and Heliotryphce, the species o f this form range along the Andes on both sides o f the
equator.

That almost terra incognita, so far at least as its zoological productions are concerned, the Andes o f La Paz,
has given us, through the researches o f M. Warszewicz, one o f the most distinct as well as one o f the most beautiful
forms yet discovered among the Trochilidse. This remarkable bird is the type o f my genus Diphlogana, to which I
have since added a second species under the name o f D. Aurora, with a mark o f reservation in case it may prove
to be the female o f D. I r is ; for the present, however, I regard it as distinct.
Genus D i p h l o g a n a , Gould.
(pi-, duplex, et <f>\oyaivos, flammeus.)
Generic characters.
Male — Bill straight and longer than the head; wings very long and pointed; tail lengthened and deeply forked;
tarsi short and partially clothed; fe e t small; hind toe sh o rt; nails moderately long and straight; crown decorated
with several luminous colours.
Female.—Unknown.

Habitat. P eru ; locality the same as D. Iris.
Dr. Reichenbach’s specific name o f Warszewiczi must, I believe, give place to that o f Diphlogana Aurora, unless
his name was proposed prior to the 12th o f April, 1853, when I read my paper on this and other new species before
the meeting o f the Zoological Society o f London, as reported in the ‘ Athenaeum ’ o f the 16th o f the same month.
The form which appears to me to range next in point o f affinity is that o f Clytolama. The two members
o f this genus, unlike their predecessors, which are from the Andes, are natives o f the low countries,—one, the
C. rubinea, being found in Brazil, and, so far as we yet know, confined to the most eastern parts o f that country;
the other, the beautiful C. aurescens, is an inhabitant o f the forests o f the upper, part o f the Rivers Madeira and
Negro.
Genus C l y t o l a m a , Gould.
(KAuroy, C e le b r is , et Xaifbs, guttur.)
Generic characters.
Male.—B ill straight and rather longer than the h ead ; wings moderately long and pointed; tail rather short,
and very slightly forked; tarsi partially clothed; fe e t strong; hind toe and nail shorter than the fore toes and nails;
crown and gorget luminous.
Female.—Destitute o f any fine colour.

By some Trochilidists it may be thought that this species should form the type o f a distinct genjis; but after
a careful comparison I believe that I have placed it in its right situation; at the same time I admit that there is
some little doubt on the subject.
I next proceed to a group o f birds o f considerable size, with lengthened straight bills, and the plumage and
markings o f which render them very conspicuous—the prevailing colours being black and white, relieved by blue
and other tints on the crown; they have small and very delicate feet, the colours o f which are either rosy or white.
I consider them to constitute a very distinct section o f the Trochilidae, and I have much pleasure in adopting for
them the generic appellation o f Bourcieria proposed by the late Prince Charles Bonaparte. All the known species
are from the Andes, over which they are spread from the southern part o f Peru to the northern part o f New Granada.
Genus B o u r c ie r a , Bonap.
