(2) The female generally has the plumage of the crown 

 darker and less olive than that of the male. 



(3) Very young male and female specimens have the entire 

 top of the head^ nape, and sides of the head dark grey, the 

 crown and nape being washed with olive ; the superciliary 

 stripe, continued along the side of the occiput, pale grey, and 

 the throat and fore-neck whitish washed with the same grey 

 tint. The male bird from Ponthierville (No. 5206), which is 

 rather older than the female, has the bill black, becoming paler 

 towards the tip, and the feet olive-green. The female from 

 Efulen, Camaroon, which has the flight-feathers still in 

 quill, and is little more than a nestling, has the entire bill 

 of a pale yellowish horn-colour, with the exception of a dark 

 stripe at the tip of both mandibles, and the legs of a pale 

 yellowish horn-colour. 



(4) In a somewhat older male bird from Ponthierville 

 (No. 5233) the crown is olive, brighter than that of the 

 adult, the superciliary stripe is of a pale somewhat indetinite 

 greenish-white ; the cheeks are much the same dusky colour 

 as the lores and the streak through the eyes ; and the 

 underparts are rather dull greyish-olive, darker and more 

 olive than those of the adult. 



(5) Adult males killed when breeding in October have the 

 pale yellowish-white eyebrow-stripe and the olive of the 

 cheek distinctly brighter than the male birds killed by 

 Mr. Carruthers in February.

The bird described by Dr. Reichenow as E. congensis and 

 believed by him to occur together with E. metitalis at 

 Leopoldville is almost certainly an immature example of the
