Humming-birds of Guatemala . 
being frequently found both in the coast-regions and also in 
the more elevated districts. 
Thus, Phaethornis adolphi is found at Yzabal and Coban ; 
Amazilia dumerillii at Yzabal and Duenas ; S clasp horns heloisce 
at Cajabon, in the “ tierra caliente ” north of Coban, and at 
Calderas in the Volcan de Fuego; Heliomaster longirostris near 
Guatemala (Constancia), Duenas, and Escuintla (Constancia). 
Some species, however, seem to be much more restricted in their 
range. 
The males of T. Candidas largely predominate in numbers at 
Cobau : of those actually dissected, the ratio is as seven males to 
one female; but, comparing these with the rest, the ratio be¬ 
comes eleven to one. 
21. HeLIOPvEDICA melanotis. 
Volcan de Fuego, Coban, and San Geronimo. 
In some of the open savannas which are scattered among the 
oak-forests of the Volcan de Fuego near Calderas, this species is 
not uncommon; in some of the (e barrancos ” also of the same 
Volcano, I have frequently met with it. 
The white mark running from the eye and the deep coral-red 
of the bill show conspicuously in the living bird. It is a very 
shy species. 
A single bird was shot and skinned by Cipriano near Coban, 
and one specimen was brought to me from the mountains of 
S. Cruz, near San Geronimo. 
/ 22. EuPHERtJSA EXIM1A. 
This is one of the commonest Humming-birds of Coban, 
being found everywhere near the city. The ratio of the males 
to the females is as ten to three. 
\f 23. Chlorostilbon osberti*, Gould. 
Duenas and San Geronimo. Not uncommon at San Gero- 
nimo. . 
The only other species of Trochilidce I have observed m Gua¬ 
temala are —Phaethornis cephalus , of the Vera Paz , Campy o 
• - This name was given by Mr. Gould to a Chlorostilbon very closely 
allied to C. caniveti, described at the Zoological Society s ce i ' 
12th, 1860.
