Adult male. Smaller, but generally resembles the preceding 

 species, except as regards the colour of the feet, a usually deeper and 

 browner tinge in the black of the mantle, and the pattern of 

 the primaries. The outermost tjuill is white for 2 inches apically 

 (with a mere hair-line of black on the shaft) in verj^ mature 

 birds, while the second quill exhibits an irregular white subapical 

 mirror; but in average adults the white on the 1st quill is turned 

 into a large subapical mirror by the intrusion of a narrow black 

 bar. In adults a year younger there is no mirror on the 2nd quill, 

 which is black with a white tip, like the 3rd quill ; at the 4th the 

 usual paler " wedge '' on the inner web begins to show, and this 

 wedge goes on increasing in extent and in whiteness at its apex, 

 until at the 7th quill it has amalgamated with the white tip ; 

 tlienccforward the quills are white terminally and only slate-colour 

 on the basal portions. Bill j-ellow, turning to red at the angle of 

 the genys ; iris white ; tarsi and toes greyish olive with yellower 



Tj))o in A\'icshaclpn Museum examined.
