Wagler’s Wood-Nymph (Thalurania? Wagleri), John Gould It has long been a question with me, as I am sure it must have been with every person who has made the Trochilidæ their study, to which genus of the family this species should be assigned: some Trochilidists may hereafter go so far as to separate it from all the genera at present proposed, and make it the type of a new one; but, after an examination of the female, which I have lately received through the kindness of M. Bourcier, I have little hesitation in associating it with the other Wood-Nymphs of the genus Thalurania, a genus comprising many species widely dispersed over the continent of America. 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."
