Berylline Amazili (Amazilia beryllina), John Gould This bird is generally known to Trochilidists by the specific name of Arsenoë; but the Berlin ornithologists tell us that it had been previously named beryllinus by the late Dr. Lichtenstein in his priced list of birds issued in 1830; and I have adopted the name proposed by my very old friend who so long filled the post of Director of the Zoological Museum of Berlin: at the same time I question the justice of the procedure, as it can scarcely be expected that names proposed in a catalogue of duplicate birds, even if accompanied by brief specific descriptions, are to be received and admitted by the scientific naturalist; for myself, I have never seen the pamphlet alluded to. 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."
