508 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-Martiu. 

 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. PsALiDOPRocxE MASSAICA. Masai Rough- winged 

 Swallow. 



PsaUdoprocne 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 forwai'ds, 

 and three or four were shot, but it was dithcult 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. 



PsaUdoprocne albiceps Sclater. 



This is supposed to be a scarce species in East Africa, but 

 I 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-Africau Hoopoe. 

 Upupa africana Bechst. 



Iris brown ; bill dark brown or black ; legs black.
