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. Arce 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. preoosti, 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.

PETASOPHOEA. 



Petasophora, Gray, List Gen. Birds, p. 13 (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 P. 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. delphince, 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 Eica and the State of Panama, and the Andes of 

 South America as far south as Bolivia. P. delphince is a widely-ranging bird of the 

 northern portion of the southern continent, and reaches the eastern forests of 

 Guatemala.
