Habitat. Brazil. 



At present the single example of this bird procured by Prince Maximilian of Wied is the only one that has been 

 seen. This type specimen is now^ before me, and I cannot do otherv\^ise than regard it as a distinct species. It is 

 very closely allied to, but a smaller bird than, E. ccerulea. 



Genus Panterpe, Cab. 



This generic name has been proposed by M. Cabanis for the beautiful new bird discovered by Dr. Hoffmann in 

 Costa Rica, of which I believe only a single example was obtained. Nothing is known with regard to the colouring 

 of the sexes.

The member or members, as the case may be, of the 



Genus Juliamyia, Bonap. ^ 



stand quite alone and apart from all the other small Humming-Birds, and bear the same relationship to the 

 Eucephalce that the Sphenoproctus Pampa does to the Campylopteri. Some of the specimens of this form have bril- 

 liantly glittering crowns ; in others this part of the head is dull-coloured ; while the plumage of the body is alike 

 in all. 



These differences have sadly perplexed me for many years ; but, after a very careful and minute examination of 

 a great number of examples from various localities, I believe I shall be right in regarding the brilliantly coronetted 

 bird as distinct from its dull-crowned ally, and in adopting Lesson's name of Feliciana^ believing that his description 

 of the bird he has so called has reference to it.

Habitat. Ecuador. 



Mr. Eraser states that at Babahoyo this species is "not very common, and only found in the deep bush, where 

 it feeds on the tops of good-sized trees," and that in Esmeraldas it was " taken catching flies among the Cacao 

 plantations. In October common everywhere; in December rare." " Irides hazel; upper mandible black; lower 

 red, with black tip."— Proc. of Zool. Soc. 1860, pp. 283, 296. 



The Mexican genus Circe comprehends, as far as our present knowledge extends, only two species. Although 

 their tails are somewhat short, they are composed of broad and ample feathers, all of which are tipped with grey : 

 in this respect they remind us of the Chlorolampis Caniveti and its allies. 



Genus Circe, Gould, 



(KtpKT}, Circe.)

Male.— Bill rather longer than the head, shghtly curved and tapering towards the tip ; wings rather long ; 

 primaries rigid ; tail rather short and shghtly forked, the feathers broad ; tarsi clothed ; feet small ; hind toe short ;

The six middle tail-feathers of both species are edged with brown as in Caniveti.
