Journ., vol. 2. p. 466. TuereE is no one species of the family of Toucans that is more common in our museums, or better known, than the present; yet, strange to say, none is involved in greater confusion: and this confusion appears to have arisen from one author having taken his characters from the description of another, without having instituted any examination for himself. Instead of going into a detailed history of this tissue of confusion, I would rather refer my readers to the elaborate paper on the subject by N. A. Vigors, Esq., M.P., in the «¢ Zoological Journal,” vol. 2. p. 466. For myself, I cannot help suspecting that, notwithstanding the yellow upper tail-coverts described by Linnzeus as characteristic of Ramphastos Tucanus, the present bird is in reality identical with that species ; and I am the more inclined to believe this, as no such bird exists in any museum, as far as I have been able to ascertain. However, upon referring to the works of Linnzus, Brisson, and Wagler, the reader may satisfy himself respecting the uncertainty which hangs over the nomenclature of the bird in question. An example of this beautiful species lived in the possession of Mr. Vigors for eight years. It is extremely common in the Brazils, whence it is dispersed throughout the greater part of South America.
