Mr. G. H. Gurney on 
in the middle of the flat Kapiti Plains, which had its mouth 
full of soft mud; it must have been fully seven miles away 
from any possible breeding-place, and the rate of flight 
must be very rapid to have enabled this bird to reach its 
nest before the mud it was carrying had become too hard 
to use. 
110. Ptyonoprogne rufigula. Fischer’s Rock-Martin. 
Ptyonoprogne rufigula (Salvad.). 
This species was only seen at Kapiti, where great numbers 
were breeding on ledges in caves, but none of the nests I was 
able to reach had eggs on April 17th. 
111. Psalidoprocne massaica. Masai Rough -winged 
Swallow. 
Psalidoprocne massaica Neumann. 
Iris brown ; bill black ; legs brown. 
The Masai Rough-winged Swallow was a rare bird, and 
the only place where I met with it was in a little open glade 
amidst thick forest near the Thika. At this spot a number 
of these little Swallows were flying backwards and forwards, 
and three or four were shot, but it was difficult to avoid 
damaging them as they are very delicate. We camped not 
very far from this locality, and on going back to the little 
clearing the following day I found the Swallows still 
hawking backwards and forwards and yet not a trace of one 
to be seen anywhere else. There must have been a very 
large and unlimited supply of insects just there. 
112. Psalidoprocne albiceps. White-headed Rough¬ 
winged Swallow. 
Psalidoprocne albiceps Sclater. 
This is supposed to be a scarce species in East Africa, but 
1 found it rather commonly distributed, and examples were 
obtained at the Thika, Kallima Theki, and Bondoni. It was 
seen singly and in small flocks. 
113. Upupa africana. South-African Hoopoe. 
Upupa africana Beehst. 
Iris brown ; bill dark brown or black; legs black.
