510 Mr. G. H. Gurney on 



instances. Four or five nests were built touching each other 

 under a projecting bit of rock, and a few feet away would 

 be a cluster of three or four more. 



117. Cypselus -SQUATORiALis. Great Equatorial Swift. 

 Cypselus ceguatorialis Miill. 



The Great Equatorial Swifts were very abundant on one 

 cliff at Longonot, where they were breeding in company 

 with the previous species, C. afinis, but higher up the 

 precipice, and I was not able to see any of their nests. 

 They fly exceedingly rapidly, and having very tough skins 

 are hard to kill. The wing-measurements of my specimens 

 were 8*1 inches. 



118. Caprimulgus fossil Mozambique Nightjar. 

 Caprimulgus fossil Hartert. 



Iris brown; bill black; legs dark brown. 

 The Mozambique Nightjar was abundant round Lake 

 Naivasha, but was not met with anywhere else. 



119. Caprimulgus FRENATUs. Salvadori's Nightjar. 

 Caprimulyus frenatiis Salvad. 



A male specimen of Salvadori's Nightjar was shot one 

 evening flying round our tents at a camp on the Athi, and 

 the following day a pair of Nightjars, which I believe to have 

 been of this species, got up at my feet, but I was unable to 

 shoot them as I was just going to fire at a Waterbuck after 

 a long and critical stalk. 



120. Caprimulgus europ^us. European Nightjar. 

 Caprimulgus europaus Linn. 



This species was abundant on Kapiti Plains. 



121. Caprimulgus lentiginosus. Freckled Nightjar. 

 Caprimulgus lentiginosus Smith. 



Bill and legs dark brown. 



This large Nightjar was observed in the thick brushwood 

 by the Thika River, but it was not very plentiful.
