Humming-birds of Guatemala. 
/ 5. PETASOPHORA DELPIIIN/E. 
Coban, Vera Paz. November. 
This Humming-bird seems to have been quite unknown at 
Coban previously to the present specimens being collected. The 
first was shot by my collector, Cipriano Prado, among some 
Salvia, in one of the mountain-hollows near Coban. I after¬ 
wards visited this place and saw one bird, but did not succeed 
in shooting it. Salvice beiug in flower in November, their 
blossoms are sought after by nearly every species of Humming¬ 
bird near Coban, this among the rest. It is a rare species 
even at Coban, and though much looked for by the Indian boys 
in consequence of my offers of reward, but few specimens were 
obtained. 
The females appear only to differ from the males in being 
smaller in size, the colouring of the ear and throat being quite 
as brilliant. Three males to one female appears to be about the 
proportion of the sexes.

Duenas and Coban. 
This species is common at Duenas, but its numbers at Coban 
are very much smaller. The sex of the young males seems 
sufficiently indicated by the colouring of the head.

Duenas, Coban, and Tactic. 
This species is also rare at Coban. The place described as 
frequented by Amazilia dumerillii is the spot where I have 
found this species in greatest numbers ; indeed, with two excep¬ 
tions, I have never met with it elsewhere near Duenas. It is a 
most pugnacious bird. Many a time have I thought to secure 
a fine male, which I had perhaps been following from tree to 
tree, and had at last seen quietly perched on a leafless twig, 
when my deadly intention has been anticipated by one less so 
in fact, but to all appearances equally so in will. Another 
Humming-bird rushes in, knocks the one I covet off his peicli, 
and the two go fighting and screaming away at a pace hardly to 
be followed by the eye. Another time this flying fight is main-
