his brown; bill black ; feet slate-colour. 



Neither of these specimens appear to be fully adult, In the male the third 

 pair of tail-feathers have the greater part of the outer web and a broad band down the 

 margin of the inner web black ; the fourth pair have a black line down the middle thii d 

 of the outer web, and the two outermost pairs are pure white. In the female (which has 

 the tail-feathers in moult) the third pair have the outer web mostly black, but wo black 

 (in the inner web, the fourth pair have a black line down the middle third of the outer 

 web as in the male, and the two outermost pairs are pure white ; moreover, the second 

 pair of normally black tail-feathers (which are worn and apparently remains of the 

 first plumage) are irregularly marked with white towards the tip. 



[A pair of the Long-tailed Pied Wagtail were obtained in the Mpanga Forest, 

 and a pair of Wagtails believed to be of the same species were seen on a stream 

 in the Congo Forest. When flying up or clown the streams in the forest they always 

 kept close to the water, and their flight was straight and swift, more like that of a 

 Kingfisher than a Wagtail. — E. B. W.~\
