It will be seen that there is considerable variation in size, 

 but the differences are apparently individual. 



Adult male examples of E. plumbea closely resemble males 

 of E. scJiisticeps, but may be infallably recognised by the 

 following characters : the lesser and median wing-coverts 

 are black margined with grey, instead of grey ; the greater 

 secondary coverts are black, the outer webs margined with 

 gre}^ instead of being uniform grey to the shaft ; the 4th 

 primary quill is longest and longer than the 5th, whereas in 

 E. schisticeps the 3rd-5th quills are subequal. 



One, an immature male, specimen «, from the Setakwa, is 

 unusually large (wing 124 mm.) : this specimen, together with 

 one from the Utakwa River, and another immature bird 

 (No. 1207) from the Mimika River, differ from the adult in 

 having the feathers of the crown streaked with black ; the 

 throat is grey and the general colour both above and below 

 paler grey. 



Mr. Claude Grant says that on the Mimika this species 

 was only noticed in the mangrove-swamps along the coast, 

 where it was quite common, the adult birds being alv/ays 

 observed in pairs. On the Utakwa River, however, it was 

 found up to 2900 ft.
