 just at that spot that the nest was never completed.

I frequently saw the White-winged Black Tit on the 

 Rahad and Dinder Rivers in March and April 1903. It was 

 generally in pairs or in parties of three or four, which played 

 a sort of "follow-my-leader" game from tree to tree. In 

 April I found a nest-hole about two feet from the ground 

 in an acacia, but the tough wood was too much for my 

 hunting-knife, and I had to leave it. 



The skin was kindly obtained for me by Mr. G. B. 

 Middleton.

Quite one of the most beautiful members of its family, the 

 White-winged Wagtail is very local, frequenting only certain 

 rocky reaches of the Nile and the smaller rivers. The 

 localities in which I have met with it are the Shabluka 

 Cataract (40 miles north of Khartoum) and the gorges of the 

 Upper Atbara and the Setit. Id these places it is abundant. 

 I once shot a specimen on the river-front at Khartoum, but 

 I never saw another there. 



In May the birds were all in pairs on the Setit, and 

 apparently breeding. 



5. Motacilla alba Linn. 



Seven specimens, $ and $ , from Khartoum. 



The White Wagtail is one of the most abundant of the 

 cold-weather visitors. No migrant arrives so regularly to 

 time, or in such numbers at once. It is a late comer 

 and stays late into the spring. At Khartoum in 1901 it 

 arrived on Oct. 19th ; in 1902 on the 18th; in 1904 on the 

 18th. (I was away in 1903 in October.) On the evenings 

 before these days not one was to be seen ; in the mornings
