JL he very beautiful species, which we have chosen for the illustration of 

 this interesting genus, is among the smallest of the true Toucans, and 

 measures in length from fifteen to sixteen inches, of which the bill, which 

 is not so disproportionate in size as in many of the others, varies from 

 two inches and three-fourths to three and one-fourth : the colour is 

 greenish-yellow, paler on the culmen, with a narrow brownish-black band 

 at the base of both mandibles, which are serrated, but not deeply, and 

 are edged with pale reddish-orange : all the upper parts, the tail, vent, 

 and thighs, are deep bluish-black, having blue and greenish reflections on 

 the back and head in different lights : the centre of the breast is very deep 

 bright orange, gradually passing round the edges, and upon the throat 

 and cheeks, into primrose-yellow, palest immediately under the throat ; 

 on the lower part of the breast it passes more abruptly into the primrose- 

 yellow, and almost forms a decided band between that colour and the rich 

 scarlet which uniformly covers the belly : the crissum and upper tail-co- 

 verts are also scarlet-red, and of a deeper shade than that of the under 

 parts : the feet and legs in the living bird are delicate blue. The species 

 is a native of Brazil, and at one time was accounted very rare and valu- 

 able ; but they must either not have been looked for in the proper places, 

 or were in some other way omitted to be sent to this country in collections.
