Art V. A Description of tioo new Birds of the Geiius 

 Pteroglossits, of lUiger. By William Swainson, Esq., 

 F.L.S., M.W.S. 



The Genus Pteroglossus has, with great propriety, been 

 instituted by the celebrated Illiger, who, in his Prodromus, 

 first defined its characters : they consist of that division of the 

 Linnsean Toucans, called by the French Aracare ; and, 

 although one of their first ornithologists has done much to 

 elucidate these singular birds, no writer has yet clearly defined 

 the species ; indeed, M. Vieillol has, in his generic work, 

 again united them to the toucans, although he adopts lUiger's 

 name for quite a different family ! I shall, for the present, con- 

 fine myself to the description of two new species, both of which 

 are now in the possession of Lord Stanley, who most poHtely 

 favoured me with them for examination. 



Pteroglossus torquatus. 

 Collared Aracari. 



P. nigra virescens, cupite nigra, colla urapigia et fascia lata 

 pectorali rubris, torque et ventre Jiavis, mandibule superiore 

 flava, inferiare alba, subfne cccruleo. 



Blackish green Aracari with black head ; red neck, rump, and 

 pectoral bar ; yellow gorge and belly ; upper mandible yellow, 

 lower one white, the end blue ; size rather less than the green 

 Aracari. Total length thirteen inches and a half; bill two 

 inches eight lines, from the gape to the tip ; upper mandible 

 convex above the margin, moderately toothed, the colour pale 

 but clear yellow, with a narrow whitish line at the margin 

 towards the base and parallel with the teeth, between each of 

 which is a short black line ; the under mandible is white at the 

 base, the other half blue, and both mandibles have a tumid 

 marginal orange line at their base, inside which in the under 

 mandible only, is a line of black ; orbits chesnut. Upper part 

 of the head as far as the nape black, wliich changes to crimson
