Humminr/ -birds of Guatemala. 271 



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 dumerUlii at Yzabal and Duefias ; Selasphoriis heloiste 

 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 

 Coban : 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. Heliop^dica 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 " 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. EUPHERUSA EXIMIA. 



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. 



23. Chlorostilbon osberti*, Gould. 



Dueiias and San Geronimo. Not uncommon at San Gero- 

 nimo. 



The only other species of Trochilida I have observed in Gua- 

 temala are — Phaethornis cephalus, of the Vera Paz ; Campylo- 



* This name was given by Mr. Gould to a Chlorostilbon, very closely 

 allied to C. caniveti, described at the Zoological Society's Meeting, J\ine 

 12th, 1860.
