Dr. Reichenbach's specific name of Warszewiczi must, I believe, give place to that of Diphlogcena Aurora, unless 

 his name was proposed prior to the 12th of April, 1853, when I read my paper on this and other new species before 

 the meeting of the Zoological Society of London, as reported in the ' Athenaeum ' of the 16th of the same month. 



The form which appears to me to range next in point of affinity is that of Clytolama. The two members 

 of this genus, unlike their predecessors, which are from the Andes, are natives of the low countries,— one, the 

 C. rubinea, being found in Brazil, and, so far as we yet know, confined to the most eastern parts of that country ; 

 the other, the beautiful C. aurescens, is an inhabitant of the forests of the upper part of the Rivers Madeira and 

 Negro. 



Genus Clytol^ema, Gould. 



(KAyroy, Celebris, et Xaifxhs-y guttur.) 

 Generic characters. 



Male,— Bill straight and rather longer than the head ; wings moderately long and pointed ; tail rather short, 

 and very slightly forked ; tarsi partially clothed ; feet strong ; hind toe and nail shorter than the fore toes and nails ; 

 C7'own s.nd gorget luminous. 



Female. — Destitute of any fine colour.

 Habitat. The eastern portions of Brazil ; common at Rio de Janeiro.

Habitat. The forests bordering the Rivers Madeira, Upper Amazon, and Negro. 



By some TrochiUdists it may be thought that this species should form the type of a distinct genus ; but after 

 a careful comparison I beUeve 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 of birds of considerable size, with lengthened straight bills, and the plumage and 

 markings of which render them very conspicuous — the prevailing colours being black and white, I'elieved by blue 

 and other tints on the crown ; they have small and very dehcate feet, the colours of which are either rosy or white. 

 I consider them to constitute a very distinct section of the TrochiUdee, and I have much pleasure in adopting for 

 them the generic appellation of 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 of Peru to the northern part of New Granada. 



Genus Bourciera, Bonap. 

 As a typical example of the form, I commence with —
