Habitat, Mexico and Guatemala. 

 " The large and showy tail of this Humming-Bird," says Mr. Salvin, " makes it one of the most conspicuous when 

 on the wing. It is common at Coban, feeding among the Salvics ; it is said also to be found in the Volcan de Fuego, 

 but I have not met with it. The females of this species are most abundant, their ratio to the males being as five 

 to two. It is not nearly so shy as its congener, C rufusT — Ibis, vol. ii. p. 260. 



" This beautiful Humming-Bird," says M. Montes de Oca, " is generally known in Mexico by the name of 

 Chupa-mirto real azul, or Royal Blue Myrtle-sucker. It arrives in the vicinity of Jalapa, Coantepec, and Orizaba 

 in considerable numbers during the months of October and November, and is mostly found feeding from a plant 

 called Masapan, between the hours of nine and one o'clock. During this time it is seldom seen to alight, and then 

 only for a very short time in any one place, but is constantly on the wing, flitting from flower to flower, describing 

 the segment of a circle in its flight, and sometimes almost touching the ground. For the remainder of the day very 

 few are to be seen, and I think it probable that they visit the woods for certain kinds of mosquitoes, with which I 

 have often found their stomachs well filled. 



" The pugnacity of this species is very remarkable. It is very seldom that two males meet without an aerial 

 battle. The contest commences with a sharp choleric shriek, after which, with dilated throats, the feathers of the 

 whole of their bodies erected on end, and their tails outspread, they begin to fight with their bills and wings, and 

 the least powerful soon falls to the ground or flies away. I have never known one of these battles last longer than 

 about ten seconds ; and in the specimens I have had under my notice in cages, their fighting has mostly ended in 

 the splitting of the tongue of one of the two, which then surely dies from being unable to feed."

Habitat. The Island of Tobae^o. 



On reference to my account of Campylopterus Villavicencio, it will be seen that I was inclined to believe the 

 C. splendens of M. Lawrence to be identical with that bird; but on reconsidering the matter, and observino- how 

 numerous and how closely alhed are the species of the genus Campylopterus, I now think it probable that it is really 

 distinct. The throat in C. splendens is beautiful blue, and the abdomen washed with green ; while in C. Villavicencio, 

 the whole of the under-surface is pure grey. Both these birds have fine metaUic-green crowns, which circumstance 

 induced me to believe that they were opposite sexes of one and the same species, and it is possible that they may 

 yet prove to be so ; but for the present I shall regard them as distinct.
