Allied Hermit (Glaucis affinis), John Gould In my account of Glaucis hirsuta I pointed out the differences which exist among specimens of this form from the Andes of Bogota and those from Trinidad and Brazil, and remarked that the former, which has the throat and abdomen suffused with green, and might therefore be regarded as distinct, had not yet received a specific appellation. 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."
