I noted the White-winged Wagtail on the Jur River at 

 Wau in January and again in March. It frequently 

 entered the verandahs of houses close to the water. I also 

 found the bird on the Chell River at Chak Chak in February 

 and March. The rivers are rocky just at both these localities. 

 Indeed, this Wagtail is hardly ever seen away from rocks.

The W^hite Wagtails arrived at Khartoum in 1905 on 

 October 21st. In 1906 I did not notice them till the 23rd, 

 on the morning of which day they were plentiful. In 1907 I 

 observed them on the 22nd. In the Bahr-el-Ghazal country 

 I only noticed them at Chak Chak and at Meshra-el-Rek 

 (April 12th, 1907). They all disappeared from Khartoum 

 by the first week in May. They were common at Suakiu 

 and at Erkowit in March 1906. 



13. MOTACILLA MELANOPE Pall. 



Since writing my first notes I have only seen the Grey 

 Wagtail a few times in Khartoum — on Nov. 10th, 1905, 

 Nov. 20th, 1906, Sept. 28th and 29th, 1907, and two or 

 three times in November of the same year.

Owing to the thickly-forested nature of most of the 

 country, and to the scarcity of water on the plains at the 

 time of my visit, I saw very few Yellow Wagtails in the 

 Bahr-el-Ghazal country. A quantity appeared at the pools 

 in a " khor '' between Chak Chak and Dem Zubeir on
