Birds from British East Africa. 
104. Muscicafa grisola. Spotted Flycatcher. 
Muscicapa grisola Linn, 
A common species everywhere. 
105. Buchanga assimilis. African Drongo. 
Buchanga assimilis (Bechst.). 
Iris red ; bill and legs black. 
We generally saw the Drongo in open forest-country, but 
except by the Thika River it was rather scarce. It was 
always conspicuous, sitting at the end of a dead bough, from 
which it would make short flights to catch the passing 
insects, and return immediately to its perch ; it has a harsh 
rather grating note. 
106. Cotile faludicola. South-African Sand-Martin. 
Cotile paludicola Tristr. 
Iris brown; bill dark brown; feet light brown. 
Common at Naivasha, where it was breeding in the rocky 
cliffs on the east side of the Lake ; also obtained at the 
Gerei River. 
107. Hirundo rustica. Common Swallow. 
Hirundo rustica Linn. 
Large flocks of H. rustica appeared on the Kapiti Plains 
in the fourth week of March, all on northward migration. 
108. Hirundo puella. Smaller Stripe-breasted Swallow. 
Hirundo puella Temm. & Sch. 
The Smaller Stripe-breasted Swallow was not uncommon 
at two or three of our camps on the Athi. 
109. Hirundo emini. Emin's Swallow. 
Hirundo emini Reichen. 
Iris brown ; bill and legs black. 
This fine Swallow was common at Naivasha, where it was 
breeding under the eaves of the hotel, though on March 14th 
none of the nests contained eggs. At Kallima Theki in 
the middle of April a pair were building in the kitchen at 
Sir Alfred Pease’s house, and were quite undisturbed by the 
constant coming and going. I shot one at a little rain-pool
