137. SELASPHORUS ARDENS, Sp. n. 
Supra viridescens: loris et regione parotica rufis, hac nigro mixta : 
subtus gula lete nitente rubra, sicut in Selasphoro platycerco : 
pectore toto, ventre medio et crisso albis: cauda sicut in specie 
precedente, rectricibus mediis purpurascenti-nigris rufo limbatis 
solum exceptis: rostro toto nigro: long. tota 2°8, ale 1:55, 
caude 1°15, rostri a rictu 0°65. 
Mas hornot. gula fusco maculata: cauda nigra, basi rufa et 
rectricibus quatuor externis rufo terminatis, mediis viridescen- 
tibus, rufo marginatis. 
Hab. Calovevora et Castillo (Arcé). 
This species has the throat coloured just as in S. platycercus, which 
is in other respects a very different species. Its nearest allies, how- 
ever, are S. flammula and S. torridus, described above ; but it differs 
from both in the coloration of the throat, and also in having the 
central tail-feathers black, edged with rufous instead of green; this 
latter distinction is more conspicuous when the tail is compared with 
that of S. fammula. The wholly black bill and the absence of the 
elongated gular feathers distinguish it from S. torridus. 
The male sent by Arcé is not in quite perfect plumage, but is so 
far satisfactory as to show a few faded feathers on the throat. These 
are bronzy, and quite different in colour from the gorget-feathers of 
either S. fammula or S. torridus. 
Selasphorus scintilla. 
V. de Chiriqui. 
The original specimens of this species were obtained by Warsze- 
wiez in this locality, where Arcé seems to have found the bird 
occurring abundantly.

Castillo; Laguna del Castillo; Cordillera del Chucu; V. de Chiriqui. 
This fine species seems to be more abundant about Castillo than 
in the district of Chiriqui. Judging from the specimens sent by 
Arcé, the males are much more numerous than the females.

Mr. Gould tells me that he now considers the Central-American 
form of this bird to be distinguishable from southern examples, 
The distinction is indeed slight ; but, so far as I can see, southern 
examples always have the blue of the head and throat considerably 
deeper in tint. 
Heliothrix barroti. 
Boqueti de Chitra; Bugaba; V. de Chiriqui. 
I fail to detect amongst the species forwarded by Arcé from the 
above localities any specimens answering to the species described by
