Adult [femaW]. Entirely glossy black above and below, -with the 

 exception of the Aving-coverts, which form a conspicuous white patch, 

 the lesser and median series being pure white, some of the latter 

 tipped with black, and the greater inner coverts of the series white 

 at the base : in fi-ont of the eye a few white feathers * ; quills 

 dusky below, browner along the edge of the inner web : " iris chest- 

 nut" {AncMeta). Total length 6-5 inches, eulmen 0-75, wing 3-85, 

 tail 2-35, tarsus 1-25. 



Professor Barboza du Bocage describes as an adult male a bird 

 exactly like the above, but having a pronounced superciliary streak 

 from the base of the biU to behind the eye. This is like the type 

 figured in the ' Ibis ' (?. c), which has the eyebrow extended to "the 

 end of the ear-coverts, and some of the feathers of the crown spotted 

 with white, from which it would appear that one sex at least, at 

 some time of its life, gets a pure white head.

* In the 'Birds of South Africa' [1. c), I have by some mistake described 

 this specimen as having a " white line in front of the eve." This seems to me 

 to be too strong an expressiop, and I cannot understand how it came to be in- 

 serted, as there are only the faintest indications of white loral plumes.
