Mr. O. Salvin on the 
tained in mid air, the belligerents mounting higher and higher, 
till the one worsted in battle darts away, seeking shelter, followed 
by the victor, who never relinquishes the pursuit till the van¬ 
quished, by doubling and hiding, succeeds in making his escape. 
These fierce raids are not waged alone between members of the 
same species. Eugenes fulgens attacks with equal ferocity Am- 
zilia dumerillii, and, animated by no high-souled generosity 
scruples not to tilt with the little Trochilus colubris. I know of 
hardly any species that shows itself more brilliantly than this 
when on the wing; yet it is not to the midday sun that it exhibits 
its splendour. When the southerly wind brings clouds and 
driving mist between the volcanos of Agua and Euego, and all 
is as in a November fog in England, then it is that Eugenes ful 
gens appears in numbers; Amazilia dumerillii, instead of a few 
scattered birds, is to be seen in every tree, and Trochilus colubris 
in great abundance. Such animation awakes in Humming-bird- 
life as would hardly be credited by one who had passed the 
same spot an hour or two before ; and the flying to and fro, the 
humming of wings, the momentary and prolonged contests, and 
the incessant battle-cries seem almost enough for a time to turn 
the head of a lover of these things. I have fifteen males from 
Duenas to one female, which I shot, but did not skin,—one male 
from Coban, and two males from Tactic. 
A “London fog” must not be understood here, as the yellow 
element is entirely wanting. 
8. Myiabeillia typica. 
Volcan de Fuego (September 6th) and Coban. 
The barrancos of the Volcano are the only localities I am aware 
of, near Duenas, where this species is found. There, however, 
it is a common bird. It is usually to be seen feeding about the 
brushwood, seeking the flowers, &c. It is a restless species, but 
shows little symptoms of fear. 
My skins from the Volcano are one female and three males. 
The proportions at Coban are very different. Here it is com¬ 
mon, being found in all the mountain-hollows, feeding among 
the Salvite. The ratio of the sexes is as twenty males to one 
female.
