 thorn-bushes, and was tlie only one met with. (See Grant, 

 Bull. B.O.C. xxi. p. 17.)

My specimen was picked up dead on a path running 

 through high grass.

These beautiful little Warblers are very plentiful in the 

 open forest and bush on the ironstone country in the Bahr-el- 

 Ghazal. I noticed them directly we reached the ironstone 

 at Ayum, and thence all along the road to Chak Chak. 

 While hopping about among the upcropping rocks strewn 

 with brown dead leaves, they harmonize with their sur- 

 roundings wonderfully. They are also very arboreal in 

 their habits, working up high into the trees, but they do 

 not frequent grass much. A better name than ferruginea 

 could hardly have been chosen for this species.

These large Broad-tailed Warblers were fairly common in 

 patches of high grass in the Khor Kobshum between Chak 

 Chak and Dem Zubeir. They are birds of extremely 

 skulking habits, clinging most tenaciously to the smallest 

 patch of cover when alarmed. I got most of my specimens 

 by burning these patches and taking a flying shot at the 

 birds as they fluttered jerkily towards the next cover. 



102. Cercotrichas podobe (P. L. S. Miill.). 



I found the Black Bush-llobin common in the bush near 

 Suakin, near Kassala, and along the Atbara. I never saw 

 it in the Bahr-el-Ghazal Province.
