Habitat. New Granada and Ecuador. 



In my description of C. angiistipennis I stated that I considered the Trochilus chrysogaster of M. Bourcier to be 

 identical with that species ; but I have since more closely investigated the matter, and I now believe that this 

 opinion was an erroneous one. I also believe that the C chrysogaster and my C. melanorhynchus are one and the 

 same bird ; for I find little or no difference in the specimens from Panama, New Granada, and Ecuador. I further 

 think it likely that the C. smaragd'ma of MM. Cabanis and Heine's ' Museum Heineanum ' is also referable to it.

Chlorostilhon assimilis^ Lawr. Ann. of Lye. of Nat. Hist, in New York, 1860, p. 292. 



Habitat. Panama. 



The following is Mr. Lawrence's description of his C. assimilis, and .his remarks on the species : — "The entire 

 upper plumage is of bronze or dull golden-green ; tail dark steel-blue ; wings brownish purple ; under plumage 

 brilliant green, golden on the abdomen, and on the throat of a bluish green ; under tail-coverts grass-green ; a 

 small white spot on the pleura ; tibial feathers brown ; bill and feet black. 



" Length 3 inches, wing 1-fg-, tail I-pV, bill yV- 



"This species is somewhat like C. melanorhynchus, Gould \_chrysogaster'], but is smaller, and the crown is 

 uniform in colour with the back, not briUiant. The latter species is also more golden on the abdomen, and has the 

 tail less forked, with the feathers narrower."

Chlorostilbon nitens, Lawr. Ann. Lye. Nat. Hist. New York, April 22, 1861. 



" Habitat. Venezuela. 



"Front and crown golden yellowish-green, very brilliant ; back and wing-coverts shining bronzed green, 

 lower part of back and upper tail-coverts shining grass-green ; under plumage brilliant green, of a bluish shade on 

 the throat, and golden on the abdomen ; tail steel-blue and forked ; wings brownish-purple ; tarsi clothed with 

 blackish feathers ; under tail-coverts bright grass-green ; upper mandible black, the under yellowish for two-thirds 

 its length, with the end black ; feet black. 



"Length 3 inches, wing If, tail 1-^-, bill ^. 



"Allied to C chrysogaster, but is smaller, and has a very brilliant crown." 



Among the smallest of the Trochilidse are the members of the form to which Dr. Cabanis has given the name 

 of Panychlora. They are all inhabitants of New Granada and Venezuela, and are known by the specific names of 

 Alicice, euchloris, Poortmanni, and stenura. They are distinguished by their dull-green colourino-, the extreme 

 shortness of their tails, and by the great difPerence in the colouring of the sexes. 



Genus Panychlora, Cab. 



The members of this genus form a very natural section among the little green Humming-Birds, very perceptible 

 to those who have paid attention to this group of birds.
