Grass-green-breasted Carib (Eulampis chlorolæmus), John Gould Some Trochilidists might be inclined to doubt the specific value of this Caribbean Humming-bird, and to regard it as a mere variety of the Eulampis holosericeus, but had they as many specimens as I have to examine and form an opinion from, I believe they would come to the same conclusion as myself, and consider it to be distinct. 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."
