26 Mr. G. L. Bates-— Field-Notes on the 



without the bird, till a man shot the bird numbered 2937 

 and secured its egg. That all the Nightjar's eggs I have 

 obtained at Bitye belong to this species I feel sure, as no 

 other species has been found there except as a temporary 

 visitor. I am sure that this is the case with the Cosmetornis 

 that I got, and the European Nightjar certainly could not 

 have laid these eggs. 



Never more than one egg is found in a place. The egg 

 that was accompanied by the bird measured 33 x 24 mm. 

 The others varied in length from 31*5 to 34'*5 mm., and in 

 breadth from 24 to 25 mm. 



[Five eggs are of a perfectly oval form and somewhat glossy. 

 The ground-colour is white or very delicate pubescent-white. 

 In four specimens the markings, which consist of brown and 

 pale lavender-grey blotches, are distributed over the entire 

 shell : in a fifth specimen almost all the brown markings 

 are concentrated into a cap at one end, while over the 

 remaining part of the shell there are a few small blotches of 

 pale lavender-grey and a few very small spots of brown. —

My single specimen of this Nightjar was shot in the 

 neighbourhood of a great bare rock several acres in extent, 

 such as are found here and there in the forest. It was the 

 same spot — a place I pass on the road to Bitye — where I 

 shot the only specimen of (Edicnenius senegalensis that I have 

 ever seen {' The Ibis,' 1907, p. 423). That the rocky locality 

 was significant for the Nightjar first occurred to me when I 

 read in Boyd Alexander's book (' From the Niger to the 

 Nile,' ii. p. 22) that he found the same or a closely allied 

 species right across from the Gold Coast Hinterland to the 

 Ubangai region, always in rocky places.
