INCE OD UG OW: 25 septima inter se fere cozqualibus ; cauda, paululum brevis, et minus gradata quam in genere Pteroglosso nominato. Bill comparatively short, broad and flattened on the culmen; furrowed on the sides, and with the base of the under mandible extending obliquely beyond the line of the eye; wings short and round, the fourth quill the longest, the fifth, sixth and seventh being nearly of equal length; ¢éail comparatively short, and not so decidedly graduated as in the true Pteroglossi. This may be considered an Andean group, for it is among those lofty mountain ranges that nearly all the species are found. They are dispersed over all parts of the temperate regions, from Bolivia on the south to Mexico on the north. They possess characters common to each other; their plumage is nearly of a uniform green, and the sexes are precisely alike in colour. The species are— 42. Aulacoramphus sulcatus : : : : ‘ Pl. XLII.

De Lattre from Nicaragua, in which I find in a note at page 84 he proposes a still further division of this family: first, Rampnomexus for the Andigena nigrirostris ; next, Rampnoxantuus for the Aulacoramphus prasinus, A. albivitta, &c.; and Pirertvorvs for Selenidera piperiwora, Pteroglossus viridis, Andigena Bailloni, Pteroglossus inscriptus, &c. As regards Rampuome us, I think any further subdivision of the Hill Toucans inadmissible: the bird upon which the Prince proposes to establish the genus has all the characters common to the other members of the section, with the exception of the black colouring of the beak, which surely must be regarded rather as a specific than as a generic distinction.
