Hob. Costa Rica, San Jose {Zeledon ^^); Panama, Volcan de Chiriqui J, Bugaba 2, 

 Bibalaz ^ (Arce). 



Our collector Enrique Arce, who worked so diligently in the western portion of the 

 State of Panama, discovered this remarkable species. The first specimen sent was a 

 female which he shot near Bugaba, but it was only when the male arrived that it was 

 described by Salvin, and subsequently figured by Gould and Mulsant in their respective 

 works. The further extension of the range of the species is proved by a specimen 

 having been obtained near San Jose, as recorded by Mr. Ridgway ^ and Mr. Zeledon ^- 



Lophornis adorabilis has no near allies, so much so that Mulsant proposed a new 

 generic name, Dialia, for it. This we think hardly necessary, and prefer to let this 

 species and also L. helence stand in Lophornis in sections by themselves.

Gouldia, Bonaparte, Consp. Av. i. p. 86 (nee Adams). 



Prymnacantha, Cabanis & Heine, Mus. Hein. iii. p. 64; Salv. Cat. Birds Brit. Mus. xvi. p. 428. 



The absence of any peculiar development of the lateral cervical feathers and the 

 deeply-forked tail consisting of very narrow pointed rectrices, the median pair being 

 very short, the outermost very long, and the general green colour of all the species 

 distinguish Prymnacantha from Lo'phomis, which it resembles in the small size of its 

 component species, and in the common character of a transverse white dorsal band. It 

 differs from Discura in the absence of the large spatules which terminate the outer 

 rectrices of that genus. 



Four species are contained in Prymnacantha, all of which belong to South America, 

 one only, P. conversi, extending northwards to the State of Panama and to Costa Rica.
