'Willis bird was fir^t described by me in the Journal of the 

 Koyal Institution near a year ago. When Professor Temminck 

 was in England, I showed him the manuscript description and 

 drawing which 1 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 waa 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. 



Total leigth twelve inches, of which the bill in extreme 

 length measures three. It is much curved, and more attenuated 

 than any of the Aracaris, being thickest at the base; from which 

 it narrows to a sharp point at the tip. The upper part is con- 

 vex, and somewhat thickened ; the sides are compressed, and 

 the upper mandible has two broad slightly indented grooves on 

 each side : the base has a few transverse wrinkles, and the ser- 

 ratures deep and unequal. The lower mandiljle half die depth 

 of the upper, the sides concave, and the teeth less. The colour 

 (in the dried bird) black ; the base of the lower and the upper 

 half of the superior mandible rufous, the base with a whitish 

 marginal line. The nostrils are more lateral than usual, being 

 placed in a line with the eye ; the orbits naked and reddish brown, 

 the feathers encircling which (particularly beneath the eye) are 

 vivid cerulean blue. The whole upper plumage is parrot green, 

 paler beneath, with a gloss of golden yellow on the cheeks and 

 sides : throat dusky white. Wings short, five inches long, and 

 rounded ; inner shafts of the quills black, margined with white- 

 ish. Tail cuneated, green, four inches and a half long, the four 

 middle feathers equal. Legs dusky black.
