Tuts is one of the oldest known species of Toucan, a figure and description of it having been published by Petiver in 1709; it occurs among the drawings by Madame Merian, formerly in the possession of Sir Hans Sloane, and now in the British Museum (where it is represented nearly of the natural size, with a small bird between its mandibles); it is also figured by Edwards, Brisson and Borowski, and it is doubtless the bird to which Linneus, in the 10th Edition of his “Systema Nature,” assigned the specific appellation of Tucanus ; as, however, this term, or rather that of Zucana, was applied by all the preceding writers in a generic rather than a specific sense, it becomes necessary to adopt that of erythrorhynchus of Gmelin for the species here represented. The synonyms given above have all reference to the present bird. The richly ornamented and elegant Ramphastos erythrorhynchus is very numerously distributed over the whole of the densely wooded fluviatile regions of the river Amazon, and Mr. John Natterer found it on
