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

 front, crown, neck, interscapulars, and back fine gray ; shoul- 

 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 large black 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 the apices of all the feathers 

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

 chin, throat, and breast an uniform fine gray ; belly, vent, 

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

 finely marked with transverse black and white lines ; tarsi and 

 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.
