Adult male. Very similar to the male of N. africana, from 

 which it differs in having the head and neck of a much darker and 

 more glossy chestnut ; also the chestnut colour of the breast is 

 darker ; there is no distinct blaekish-hrown collar round the neck, 

 separating the chestnut upper portion from the lower cue ; no 

 white spot on the chin ; back and scapulars brown with no wavy 

 lines, nor minutely sprinkled with white. Size nearly the same 

 as that of N. africana : " iris white ; bill bluish grey, with the base 

 and the edges black; feet greenish brown " {Grandidier). Total 

 length about 15-5 inches, wing 7*8, tail 2-5, culmen 1-75, tarsus 1-2. 



I have seen a second specimen in Eothschild"s collection, abso- 

 lutely identical with the type.
