Venezuela and the Andes of New Granada. “In the district of El Mineral” in New Granada, says Dr. Merritt, “there has been a slight attempt at culti- vation of the soil and planting of fruit-trees. The Orange, the Guama, and Guayava trees are the most numerous, particularly the last-named, which is very prolific, bearing nearly throughout the year fruit in all its stages from the blossom to maturity. Consequently the Guayava tree is the favourite resort of the Humming-Bird. I often watched these little creatures feeding and quarrelling around a tree near the door of my palm-leaf hut ; and soon my attention was attracted to one much smaller than the rest, whose pugnacity and indomitable ‘pluck ’ greatly amused me. Upon closer examination of this diminutive feathered warrior my interest increased, as I soon became convinced that it was new to me. I frequently afterwards saw numerous specimens of it, and almost invariably encountered them feeding from the blossoms of the Guayava, and I therefore conclude they are quite local in their habitat.” Genus Myrapetiia, Bonap. This is a very distinct generic form. Like that of Klais, it contains but a single species, a delicately-formed bird inhabiting Mexico and Guatemala. The male is decorated with a brilliant green gorget, entirely absent in the female. a feature which is 236. MyIAaBEILLIA TYPICA : : ‘ : Baucis Abeillei, Reichenb. Aufz. der Col. p: 13.

Here, however, it is a common bird. It is usually to be seen feeding about upon 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 common, being found in all the mountain-hollows feeding among the Salvie. The ratio of the sexes js as twenty males to one female.”—Salvin in Ibis, vol. ii. p. 262. I must now direct the notice of my readers to some of the most chaste and elegant species yet discovered of this or any other family of birds—namely, the members of the genera Heliactin, Heliothriv, Schistes, and Petasophora. Genus Heiacrin, Bore. The single species of this genus stands alone for the resplendent and richly coloured tufts of feathers which spring from above and behind the eye. 237.

Theil iii. p. 64, Habitat. Brazil, particularly the district of Minas Geraes. The female of this species, like that sex in the genus Heliothriv, has a longer and more ample tail than her of the succeeding genus. Genus Heuiorurix, Bore. This, like the last, is a very well-marked form, of which two species are natives of Central America and New Granada, one of the regions of the upper Rio Negro, and two of the rich country of Brazil. They are all distinguished by being decorated with beautiful blue tufts on the sides of the neck, relieved by glittering green o of them have rich blue crowns; there is Y
