Colour. — The upper part of the head light pearl-grey with a dusky shade; 
the cheeks white, margined behind by a black crescent ; the neck and the 
under parts pure white ; the back and the wings a glossy greenish black ; 
several of the shoulder feathers and secondary quill coverts nearly white, and 
with the broad white edgings which occur upon the outer vanes of two or three 
of the innermost secondary quill feathers, they form a continuous white stripe 
along the wing. All the primary quill feathers, with the exception of the 
first, have their inner vanes crossed by a broad white bar, that of the inner- 
most being much nearer to the extremity of the feather than the outer- 
most ; the secondary quill feathers all broadly tipt with white. The two 
middle tail feathers greenish black ; the two outermost of each side pure 
white, or with only a slight greenish black spot at their bases. The inter- 
mediate feathers greenish black towards quills, white towards tips. Bill 
black • feet pale yellow ; claws livid brown. Eyes dark brown, and sur- 
rounded by a narrow membranous ring of a bright yellow colour.
