Juilamya (Juliamyia typica), John Gould In the rounded and almost cuneate form of the tail, this bird differs from nearly all the known species of Humming-birds; it has therefore been made the type of a genus under the title of Juliamyia. 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."
