254 Mr. A. L. Butler on the 



228. Circus macrurus (Gm.). 



229. Circus ^eruginosus (Linn.). 



Both these Harriers were seen along our route in the Bahr- 

 el-Ghazal Province. 



230. Serpentarius secretarius (Scop.). 



Since writing my previous notes I have met with the 

 Secretary- Bird perhaps eight or nine times in all, at the 

 following localities : between Gedaref and theAtbara^ between 

 Renk and Kaka on the White Nile, and in the Bahr-el- 

 Ghazal Province between Chak Chak and Wau and at Dud 

 Mavok. 



A nestling was brought to me from the White Nile in 

 December 1907, and I tried to rear it, but the long slender 

 legs never acquired strength, and gradually became so 

 distorted that I had to destroy the bird. 



231. LopHOGYPS occipitalis (Burch.)? 



An immature Vulture, caught at Khartoum in 1906, 

 which I now have alive, appears to me to belong to this 

 species. 



232. Gyps rueppelli (Brehm). 



Riippeirs Vulture often visited our camps in the Bahr-el- 

 Ghazal country when there was meat about. 



233. PsEUDOGYPs africanus (Salvad.). 



The African White-backed Vulture was common near 

 Chak Chak, and south towards Dem Zubeir. 



234. Neophron percnopterus (Linn.). 



Abundant everywhere from Suakin to Kassala, and fairly 

 common throughout the part of the Bahr-el-Ghazal Province 

 which I traversed. 



235. Neophron monachus (Temm.). 

 Much more numerous than the last species. 



236. Ibis ^thiopica (Lath.). 



237. Geronticus hagedash (Lath.). 



Both Sacred and Hagedash Ibises were common at all 

 the rivers and "khors" which we visited in the Bahr-el- 

 Ghazal Province.
