One of those genera which give but little trouble to the ornithologist is the genus Petasopuora, all the species having characters in common, while each has its own peculiar distinction either in colour or markings. The sexes are alike in colour, but the females are always much smaller than the males. This is strictly an Andean group, most of the species being found in those elevated regions from Mexico in the north to Bolivia in the south; one species, the P. serrirostris, inhabits Brazil.

I have never seen a second example of this singular bird, which departs from the ordinary species, and assimilates somewhat to the P. Delphinæ.

“The barrancos of the Volcan de Fuego are favourite resorts of this species. A specimen obtained at Duefias on the 15th of September was the only one I saw out on the llano, as the bird is usually found in the dense forest.”—Salvin in Ibis, vol. ii. p. 260.

“This Humming-Bird seems to have been quite unknown at Coban previously to the collection of my specimens. The first was shot by my collector, Cipriano Prado, among some Salvia, in one of the mountain hollows near Coban. Salvie being in flower in November, their blossoms are sought after by nearly every species of HummingBird near Coban, and this among the rest. It is rare even at Coban; and though much sought for by the Indian boys in consequence of my offers of reward, but few specimens were obtained.
“Three males to one female appears to be about the proportion of the sexes.” —Salvin in Ibis, vol. ii. p. 261.
