Thorn-bill (Ramphomicron microrhyncha), John Gould In the accompanying Plate, I have vainly attempted to illustrate this very lovely species, which (strange as it may seem) always conjures up in my mind a remembrance of the glow-worm, whose evening torch so charmingly illumines the dark lane-sides of our own country; for indeed in its plumage, a gleam of intense lustre is contrasted with the tone of the general plumage. 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."
