Bill dark horn colored ; orbits and cere inclined to orange ;

 ders and scapulars the same, slightly variegated, however, by 

 narrow dusky lines, and most of the latter besides have also 

 a large black blotch towards their tips. Primary wing coverts 

 dark gray, each with a largeyblack blotch ■ towards the tip, 

 which last in all of them is white ; secondary coverts the 

 same, only the gray is a little lighter. Primary wing feather . 

 gray towards quills, elsewhere shining black, with the ex- 

 ception of some of the innermost, which are white ; seconda- 

 ries principally gray, having each a broad black bar towards 

 tip, which itself is white. Tail long, rounded, shining green- 

 ish black, with a broad band of white mottled with black 

 towards its extremity, and £he apices of all the feathers 

 white, as well as a little of the vanes of each towards quills ;

 insides of shoulders, hinder part of back, and whole of thighs

 toes yellowish brown ; claws dark horn colored. Length two 

 feet four inches. Found, though very seldom, in the eastern 

 districts of the colony and in Caffreland, as also in Madagascar. 



Obs. — Some years ago I saw a specimen of this species, 

 though in a very different plumage, viz. chiefly brown; which 

 was, doubtless, either a young bird, or else the female, if her 

 color differs from the male.
