Subse- 5b a 5 quently he published in Oken’s “ Isis” the description of a fifth new species under the name of Pteraglossus Beauharnaisti. His Ramphastos Le Vaillantii is merely the description of the faded R. erythrorhynchus, figured by Le Vaillant on his fourth plate ; his Ramphastos callorhynchus 1s identical with the A. carinatus of Swainson ; his 22. Forsterorum is taken from the fifth plate of Le Vaillant, which is said to be a represen- tation of a bird made up from A. Ariel and R. Cuvieri; his R. erythrosoma cannot be identified with any known bird; the characters were taken from Le Vaillant’s sixth plate representing a specimen which had probably been tampered with by the bird-mounter, a much to be reprehended, though not unfrequent practice ; lastly, his Prerog/ossus Poéppigi is identical with his Pe. Beauharnaisu. Both Prince Charles Lucien Bonaparte and Mr. G. R. Gray consider the Ramphastos maximus of Cuvier to be identical with the R. erythrosoma of Wagler, which, as above stated, has been founded upon a made-up specimen.
