Hab. Costa Rica, San José (Zeledon*®); Panama, Volcan de Chiriqui!, Bugaba2, 
Bibalaz ? (Arcé). 
Our collector Enrique Arcé, 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 José, as recorded by Mr. Ridgway and Mr. Zeledon 4. 
Lophornis adorabilis has no near allies, so much so that Mulsant proposed a new 
generic name, Lvalia, for it. This we think hardly necessary, and prefer to let this 
species and also L. helene stand in Lophornis in sections by themselves.

PRYMNACANTHA. 
Gouldia, Bonaparte, Consp. Av. i. p. 86 (nec 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 Lophornis, 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.
