Colour. — The upper part of the head lijiht 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 c[uills, 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.

 the tail ; the fourth quill feather the longest, the third and fifth of equal 

 length, and a little shorter than the fourth ; the second and eighth nearly 

 equal, and considerably shorter than the third ; the first not half the 

 length of the fourth. Tail even or very slightly rounded. Tarsi rather 

 long, covered in front by transverse plates, and behind by a continuous
