The Lesser Whitethroat is, next to Hypolais pallida, the 

 commonest of our migratory Warblers. It remains with 

 us until the end of May.

The Rufous Warbler is a fairly common and generally 

 distributed bird in the winter and spring. I have seen it 

 as far east as the Setit and in Western Kordofan. Its 

 numbers are conspicuously increased at the time of the north- 

 ward migration in March. Whether any remain to breed in 

 the Soudan I do not know, but I have seen it as late as the 

 beginning of June. 



100. Cossypha heuglini Hartl. 



a. <J? Bahr-el-Ghazal, March 1, 1902. 

 I have only met with this bird in the thorn-forests of the 

 Bahr-el-Ghazal, where I saw it fairly often. 



101. Pratincola rurutra (Linn.). 



The Whinchat is a rare winter visitor. I noted it at 

 Khartoum on September 7, 1901, and on several following 

 days. I shot an example on February 2, 1903, but I 

 accidentally trod on the bird while searching for it in a 

 tall bean- crop, and thus spoilt it for skinning.

The Stonechat is a scarce winter visitor. I have only met 

 with it in the bean-fields and other cultivated places round 

 Khartoum, and by no means frequently. 



103. Ruticilla phq;nicurus (Linn.). 

 a. <$. Khartoum, Nov. 20, 1902. 



The Redstart is common between September and March, 

 and I have seen it in its winter plumage from Gedaref to 

 Kordofan, and south to the Bahr-el-Ghazal. In its habits
