486 Mr. G. H. Gurney on 



was " held up " by an angry rhinoceros ; and birds were often 

 shot, especially Weavers and smaller Warblers, which I did 

 not know ; these after being skinned were at once packed 

 away, and I was unable to take any notes of their habits even 

 if we came across the species again. This accounts for so 

 many forms being represented by only single specimens in 

 the collection. We would often get to a splendid locality 

 for birds and be only able to stop there one night, when we 

 required a week at least. 



The following notes are on the birds which were actually 

 obtained ; many other species were seen, but when not 

 satisfactorily identified I have made no mention of them. 

 I am sure that there is still a great deal of good ornithological 

 work to be done in this most fascinating and beautiful part 

 of East Africa, especially in the wide belt of forest-country 

 extending inland from Mombasa and the coast for some 

 twelve or fourteen miles, and also in the large tract of 

 little-known country to the west of Lake Naivasha, on the 

 fringe of which I camped and where I found many birds 

 which 1 had not seen before. 



Well-worked though the country has lately been, I feel 

 sure there are new forms and possibly new species still to be 

 discovered. 



1. CoRVULTUR ALBicoLLis. Whitc-neckcd Raven. 

 Corvultur albicollis Less. 



Iris brown ; bill brown ; feet brownish black. 



The White-necked Raven was plentiful all round Theki, 

 while at our camp at Bondoni several would come every 

 evening and sit on a dead tree quite close to the tents and 

 were tame and confiding ; a pair had taken up their quarters 

 on a small rocky kopje near Theki, and twice flew out of a 

 little cave at the top : they may have been breeding, but it 

 was impossible to get into the cave to see if there was a nest. 



2. Heterocorax capensis. African Rook. 

 Heterocorax capensis Licht. 



Iris dark brown; bill and legs black. 

 Specimens of the African Rook were obtained at Naiv- 

 asha ; it was seen nowhere else.
