species inhabiting pine forests of Mexican highlands, another in Guatemala, two or three others in mountains 
of northern South America.) 
2 As a subgenus of Zrochilus, in accordance with the A. 0. U. Check List, but in reality a very distinct 
genus.

malan, and two Bahaman species.) 
4 Campylopterus Swatns., Zool. Jour. 1826, 328. Type, Trochilus largipennis Bopp. (One Mexican species, 
—a splendid bird,—one peculiar to Guatemala, and several in northern South America. The first, 0. hemileu- 
curus (Licut.), is the largest hummingbird found north of the Isthmus of Panama, being nearly six inches in 
length. It is very possibly the species to which Dr. R. W. Shufeldt, U.S.A., refers in a letter dated June 9, 
1886, as having been seen by him the day before, near Fort Wingate, New Mexico, and which he described as 
being “ fully large enough for Eugenes fulgens, and whirred like an old quail.”
