Puce-throated Humming-Bird (Aphantochroa gularis), John Gould If this bird had not a small patch of luminous colour on the throat, white under tail-coverts, and a somewhat more lengthened bill, it would so closely resemble the Aphantochroa cirrhochloris that one might almost be induced to believe it to be identical with that species. 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."
