161. Merops pusillus P. L. S. Miill. 



I saw this little Bee-eater at intervals the whole way from 

 Khartoum to Chak Chak on my Bah.r-el-Ghazal trip. 



162. Merops virtdis Linn. 



The Green Bee-eater was met with occasionally between 

 Wau and Chak Chak. 



163. Merops nubicus Gm. 



The Keel Bee-eater was very abundant as far as I travelled 

 in the Bahr-el-Ghazal. 



164. Upupa epops Linn. 



Hoopoes were very numerous on the Erkowit plateau 

 during the last ten days of March 1906. A dozen or twenty 

 of them would often be in sight at the same time. I also 

 saw them in Suakin. In the Bahr-el-Ghazal country they 

 were scarce along the route which I followed ; I only saw 

 about half a dozen in all.

f ^•. IWau, 25. 1.07. 



These Red-billed Wood-Hoopoes were frequently seen 

 along our route in the Bahr-el-Ghazal Province, usually near 

 clearings or in the more open parts of the forest. I also 

 saw them in some of the " khors/' where there were 

 palms, between Suakin and Kassala, and located an inac- 

 cessible nest in May 1906. It was in a neat round hole in 

 a rotten palm, some twenty-five feet from the ground. 



166. ScoPTELUs NOTATUs Salvin. 



This Wood- Hoopoe was scarce in the country we traversed 

 in the Bahr-el-Ghazal Province. I only noted it at Doleiba 

 and Bir-el-Girud. 



167. BucoRVus ABYSsiNicus (Bodd.). 



The Abyssinian Ground Hornbill was frequently met with 

 in small parties of four or five, at various points between 

 Meshra and Chak Chak.
