Mr. G. H. Gurney on 
was “ held up 33 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 w r ere 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. White-necked 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.
