in some extending a little distance below the chin, in others 
almost reaching to the breast, I do not deem it a sufficient 
character upon which to establish a species, and have con¬ 
sequently placed H. phainolcema as a synonym of H. auri - 
culatus.

This species was first described by Bourcier (/. c .) from 
specimens contained in the Paris Museum, sent from Car¬ 
tagena by M. Barrot, who was at that time stationed there 
as the French Consul-General. In 1855 Mr. Gould rede¬ 
scribed it as H. purpureiceps; and in his Introduction to the 
Monograph of the Trochilidse he gives to a form of this 
species, which he separates on account of the metallic colour¬ 
ing on the head being restricted to the crown, the name of 
H. violifrons. I find in my collection specimens of H. barroti, 
procured on the volcano of Chiriqui by Arce, which repre¬ 
sent both the forms separated by Mr. Gould, thus showing 
that the character he gives is not indicative of specific rank; 
for we cannot suppose that two species so closely allied as to 
require very keen examination to perceive their differences 
are to be found inhabiting the same country, much less the 
same mountain. It would thus seem necessary to place H 
violifrons as a synonym of H. barroti, which I believe to be 
its proper place. 
Genus Calliphlox. 
But two species are at present included in this genus, one 
of them being among the most common of this family. They 
are characterized by long, slender, deeply forked tails, and
