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 equatorialis. Great Equatorial Swift. 
Cypselus cequatorialis Mull. 
The Great Equatorial Swifts were very abundant on one 
cliff at Longonot, where they were breeding in company 
with the previous species, G. affinis , 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 8T inches. 
118. Caprimulgus fossii. 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. 
Caprimulgus frenatus Salvad. 
A male specimen of SalvadorPs 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^eus. European Nightjar. 
Caprimulgus europceus 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.
