Birds of Gazaland. 393 



156. Cypselus caffer. African White-rumped Swift. 

 Rh., P. On September 25tli large companies of a small 



black Swift, wliicli I have little doubt was referable to this 

 species, wxre dashing madly with shrill cries about the face 

 of the huge rugged cliffs of the Chimanimani Mountains, 

 and frequently visiting the overhanging ledges of rock, and 

 especially a cave in the form of a machicoulis, where they 

 were doubtless breeding. I also saw these Swifts in large 

 numbers on the Nyahode River earlier in the same month, 

 while a considerable party passed over Chirinda on 

 November 3rd. In the lowlands I found them numerous 

 during the first half of January in patches of Palmyra palm 

 country, between Chitnbuya and the Umtefu, and at one or 

 two points between this river and the Zinyumbo Hills. 



157. Cypselus .equatokialis v. Miill. 



Apus aquatorialis Reichenow, Vog. Afr. ii. p. 379. 



P. This is the Swift referred to in my last paper {' Ibis,' 

 1907, p. 280) as Cypselus sp. inc. It agrees very well with 

 specimens in the British Museum. It has not previously 

 been recorded south of Nyasaland. 



158. Caprimulgus fervidus. Fiery-necked Nightjar. 

 (C. rufiyena of my previous paper, 'Ibis,' 1907, p. 280.) 



Chindao : " Muswerahope." Singuni : '' Isavolo." (Both 

 names are applied to Nightjars in general.) 



Rh., P. In November 1906 I found two eggs of this 

 Nightjar lying in a slight depression of the ground in a 

 fine clump of Acacia caffra beside my camp on the 

 Kurumadzi. They were very pale salmon-pink, freckled and 

 spotted all over with a slightly darker shade of purplish 

 pink. The sitting bird allowed a very near approach before 

 rising, but, once flushed, would sometimes remain away 

 from the nest for hours together. About Chirinda pairs 

 of this Nightjar sometimes regularly frequent such isolated 

 forest-remnants, consisting of a few trees each, as still hold 

 their own on the grassy slopes. Both there and on the out- 

 skirts of the forest itself they frequently settle lengthwise on 

 the larger branches of such reddish-barked trees as Bersama
