Tyrian-Tail (Metallura tyrianthina), John Gould The Metallura tyrianthina was first described by the late Mr. George Loddiges in the “ Proceedings of the Committee of Science and Correspondence of the Zoological Society of London” for the year 1832; it afterwards received the name of Allardi from M. Bourcier in 1839, and that of Paulinæ, in honour of Mademoiselle Pauline Barthod, from M. Boissonneau, in 1840. 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."
