Birds from British East Africa. 
68. Cratekopus hypoleucus. White-bellied Babbler. 
Crateropus hypoleucus Cab. 
The White-bellied Babbler was common at Kallima Theki 
and was always seen in large family parties, frequenting the 
low bushes and trees in the dry dongas. When disturbed, 
the birds will fly one after the other from tree to tree, 
following each other almost in single file. They were very 
noisy, and one which I kept alive for some weeks in a cage 
would commence a kind of discordant chuckling at daybreak, 
which it kept up throughout the day. I fed this bird on 
caterpillars and insects, and I believe that if it had not been 
rather heavily shot in the wing it would have lived, as it 
became perfectly tame and confiding. 
69. Pycnonotus layardi. Black-capped Bulbul. 
Pycnonotus layardi Gurney. 
Iris brown; bill and legs black. 
Abundant everywhere. 
70. Chlorocichla mombas^:. Mombasa Bulbul. 
Chlorocichla mombasce Shelley. 
The Mombasa Bulbul, in my experience, was a rare bird, 
and only one female was shot at Kibwezi, on April 7th. 
71. Phyllqscopus trochilus. Willow-Wren. 
Phylloscopus trochilus (Linn.). 
72. Hypolais pallida. Olivaceous Tree-Warbler. 
Hypolais pallida (H. & E.). 
Iris brown ; bill and legs dark brown. 
The Olivaceous Tree-Warbler was very common every¬ 
where. 
73. Acrocephalus phragmitis. Sedge-Warbler. 
Acrocephalus phragmitis (Bechst.). 
This species was shot at the Gerei Biver and Kallima 
Theki, but I did not see it at Naivasha. 
74. Sylviella jacksoni. Jackson's Bush-Warbler. 
Sylvietla jacksoni Sharpe. 
Jackson's Bush-Warbler was not often seen and only in 
the thickest scrub.
