4. Lampornis veraguensis.

L. prevosti similis, sed gula tota micanti-viridi, colore nigro omnino absente facile distinguendus. (Descr. 
maris exempl. typ. ex Chiriqui. Mus. Brit.) 
Hab. Panama, Volcan de Chiriqui (Warszewiez 1), David (Bridges 1°, Hicks **), Cor- 
dillera del Chucu, Calobre (Arcé 5), Agua Dulce (Herrera, in U.S. Nat. Mus.). 
Gould’s description of this species was taken from specimens sent to him by Warsze- 
wiez from Chiriqui, and the bird has since been found in the same district by several 
more recent travellers. Arcé also met with it at Calobre, halfway between Chiriqui 
and Panama. 
The range of the species is very restricted, and probably does not extend beyond the 
western half of the State of Panama. In Costa Rica the allied form, L. prevosti, is 
found, and at Panama L. violicauda. 
As a species L. veraguensis is easily distinguished, for the whole throat is glittering 
green, the middle as well as the sides; in all the allied forms the middle of the 
throat is black.

PETASOPHORA. 
Petasophora, Gray, List Gen. Birds, p. 18 (1840) ; Salv. Cat. Birds Brit. Mus. xvi. p. 105. 
In this genus the feathering of the forehead is carried further along the bill than in 
Lampornis, so that the nasal covers are almost hidden. Petasophora has also a pecu- 
liarity in the conspicuous elongated glittering blue auricular tufts, which are to be 
found in every one of the species. The character of the coloration of the throat is also 
peculiar, each feather showing a dark disc with a glittering margin in certain lights. 
The tomia of the maxilla are rather strongly serrate, so much so that a Brazilian species 
bears the name JP. serrirostris from this feature. 
Seven species are included in Petasophora, one of which, however, is of doubtful 
value. 
All the species inhabit mountain-ranges, most of them living at a considerable 
elevation. P. delphine, though also a bird of the mountains, likewise visits the lower 
grounds. 
Of the three species found within our limits, P. thalassina inhabits Southern Mexico 
and Guatemala, P. cyanotis Costa Rica and the State of Panama, and the Andes of 
“South America as far south as Bolivia. P. delphinw is a widely-ranging bird of the 
northern portion of the southern continent, and reaches the eastern forests of 
Guatemala.
