Young. Above bright ferruginous red, the head and hind neck 

 streaked with blackish, the vrings entirely nifous, the shafts of the 

 quills above black, and the primaries barred with black on the inner 

 web near the base ; upper tail-coverts and tail black, the latter 

 largely spotted with white, as in the adult, the two outer feathers 

 more or less bright red, barred with black, which is overspreading 

 the whole feather, showing that the change of colour in the tail is 

 gradually assumed without a moult ; sides of the face rufous brown, 

 streaked with black, the lores buff; under surface of body buSy 

 white, the throat narrowly, the breast more broadly streaked with 

 dark brown, somewhat tinged with rufous ; the abdomen, thighs, 

 and under tail-coverts rich buff, unstriped ; under wing-coverts 

 yellowish buff, also extending over the base of the quills. 



Another young specimen in Mr. Wallace's collection has the throat 

 and breast thickly streaked with black, which also extends over the 

 head, and gives a mottled appearance to the interscapulary region. 

 This bird also shows the gradual spreading of the black on the red 

 tail, a most anomalous change of plumage, as the tail-feathers are 

 generally changed by a direct moult in the Bii-ds of Prey. 



Adidt male. Above blackish slate-coloiu', inclining to clear bluish 

 grey on the head and neck, and to pale cinereous on the sides of 

 the face ; throat white, washed with greyish ; remainder of under 

 surface clear vinous salmon-colour, the lower abdomen, thighs, and 

 under wing- and tail-coverts pure white ; quills slaty black, white 

 at base of inner web, with some bars of blackish on the under 

 surface ; tail slaty black, slightly tipped with white, and crossed 

 underneath with two bars of white, this being confined to the inner 

 web ; cere above the nostrils and bill black; orbits orange-yeUow; feet 

 deep orange-yeUow ; iris chrome-yeUow. Total length 11'5 inches, 

 culmen 0-8, wing 6-3, tail 5-5, tarsus 2. 



Female. Similar to the male, but shghtly larger. Total length 

 12 inches, culmen 0-9, wing 6-7, tail 5-8, tarsus 2.
