Generic Type _Aracari Toucan_ Lath. * * * * * SPECIFIC CHARACTER. _P. viridis, subtus pallidior; jugulo albescente, circa oculos caeruleus; rostrum duobus sulcis longitudinalibus incisum._ Green Aracari, beneath paler; throat whitish, round the orbits blue; bill with two lateral longitudinal grooves. P. sulcatus. _Swainson, in Journal of Royal Institution, vol._ 9. _p._ 267. * * * * * All those species of the Linnaean Toucans having a long wedge-shaped tail, and the nostrils passing through the upper part of the bill, are comprehended by Illiger and other continental writers under this genus. They have been called by the French Aracari; which name I have retained as an English generic distinction. They inhabit the same country and situations as the real Toucans, which are distinguished by having a short, broad, and even tail, and the nostrils placed behind the bill. A fine example of this very rare bird I first met with in the small collection sent to my excellent friend, E. Falkener, Esq. from the Spanish Main. I have since noticed another which was in Mr. Bullock's museum, and is now in the possession of Lord Stanley: these are the only two specimens known. This bird was first described by me in the Journal of the Royal Institution near a year ago. When Professor Temminck was in England, I showed him the manuscript description and drawing which I had then made: he assured me he had never seen the bird before, otherwise than in Bullock's museum. A short time after, my account of it was published. I observe, however, that in the new edition of his Manuel he gives this name to a new bird of his own: no description however follows, and it is therefore impossible to say if the Professor intends it for this identical species. We must postpone any further observations on this family, and conclude by giving the original description above alluded to.
