This is black above, bat, instead of the small round yellow 

 spots or dots on the crown of the adult female, there are 

 very small whitish shaft-streaks to the black feathers of the 

 crown. The throat is white with narrow black bars.

Many nests, containing nestlings or eggs, have now been 

 found. These have been confined, so far, to the months 

 of March and April and from August to November. In 

 several cases the sitting bird killed or caught on the nest 

 proved to be a male. 



The nestling has the inside of the mouth slaty-black and 

 the tongue yellow, so that when the mouth is open the 

 tongue is very conspicuous. The number of cubital remiges 

 in several nestlings was at least nine (it was uncertain 

 wdiethcr another one was a quill or a covert). Tlie number 

 in Colius a-ffinis was found by Mr. Pycraft (' Ibis,' 1907, 

 p. 233) to be eight.

Neumann describes several well-marked characters in 

 which this species differs from typical E. gularis, and these 

 are all to be seen in my birds except as regards the blue 

 colour on the basal part of the middle tail-feathers ; this 

 is well-marked in only one of them, No. 3226, wdiich may 

 have been a male; in the others those feathers shew jnly a 

 bluish tinge when held in a certain position. 



This is a forest species, while E. afer is a bird of open 

 country ; the latter has been found at Bitye (' Ibis,' 1907, 

 p. 428) in a district where there is much cultivated or old
