Dr. Latham observes on this species, that excepting where the grey colour pervades, "the rest of the body is olive green, excepting the quills, which are deep green;"--this may be the female. He adds a quotation from Pernetty, who describes a bird from Monte Video, something near this; but which, from having a very long tail, a flesh-coloured bill, &c. may probably be distinct. The live bird could not be conveniently measured, but it is rather larger than the red-shouldered Parrakeet, (figured at pl. 62.) The skin round the eye white, and the irides hazel; the whole upper part of the plumage is a beautiful grass green, changing according to the light into different shades; the top of the head, the quill feathers, and end of the tail, greenish blue, in some lights appearing quite blue; the sides of the head, ears, and throat, as far as the breast, bluish grey; all the remaining under plumage yellowish green, with a shade of orange in the middle of the body and vent; bill and legs dark grey; this latter colour is so unusual in this tribe, that I at first thought it indicated an imperfect plumage, but I have now seen it at two different seasons of the year without any variation whatever. It is probably a South American species. * * * * * Pl. 90 [Illustration] PTEROGLOSSUS inscriptus, _Lettered Aracari._ * * * * * GENERIC CHARACTER.--See Pl. 44. * * * * * SPECIFIC CHARACTER. _P. fusco-viridis, capite gulaque nigris (feminae castaneis;) uropygio rubro; abdomine flavo; rostri fulvi culmine, basi et apice nigris; marginibus dentatis, lineis nigris inscriptis._ Obscure green; head and throat black, (in the female chesnut;) rump crimson; body yellow; bill fulvous, the top, base, and tip, black; the margins dentated, and marked with black lines resembling characters. * * * * * I was put in possession of this rare and unknown bird, by the dispersion of the most magnificent assemblage of natural productions that ever marked the zeal of an individual, or ornamented the capital of this kingdom. Mr. Bullock's Museum is now scattered; yet the objects it comprised were deemed worthy of enriching the public repositories of every nation in Europe; who sent their learned men to purchase with avidity, and share in the spoils of a Museum, the dispersion of which will be long regretted by the learned, the inquiring, and "the many."
