Lanceolate Hermit (Glaucis lanceolata), John Gould Many years have now elapsed since I received, direct from Para, three specimens, all of which appear to be fully adult, of a species of Glaucis which M. Bourcier, of Paris, as well as myself, considers to be distinct from any of those already described. 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."
