 of northern South America.)

 — a splendid bird, — one peculiar to Guatemala, and several in northern South America. The first, C. hemileu- 

 ciiriis (Light.), 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. E. 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 Eufjenes fulgens, and whirred like an old quail."
