Dumeril’s Amazili (Amazilia Dumerili), John Gould I have but little doubt that the bird figured in the accompanying Plate is the “Ornismya Dumerili” of Lesson’s “Histoire Naturelle des Oiseaux-Mouches,” Supplement, p. 172, pl. 36; at the same time it is necessary to observe that, if so, Lesson’s figure is maccurate, inasmuch as, I believe, the red colouring on the sides of the neck and ear-coverts represented in his drawing is due to the wetting of the feathers in the process of mounting the specimen, which has converted the original shining green colour into red; the outer tail-feathers being tipped with rufous, also indicates that the figure was taken from an immature bird. 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."
