Southern Thorn-bill (Ramphomicron Vulcani), John Gould The single specimen I possess of this curious bird was brought to this country by M. Warszewicz, and was, I believe, collected during his last journey into Bolivia; but of this I am not certain. This illustration has been restored to its original vibrancy by enhancing colors and removing unwanted marks. A monograph of the Trochilidæ, or family of humming-birds was published between 1849 and 1887 by English ornithologist John Gould. This monumental work depicts and describes all the known species of hummingbirds at the time - comprising 418 lithographic plates and information on 537 species."
