264 Mr. J. H. Giirney on additional Species of Birds 



As on former occasions, I have appended to each species the 

 note which Mr. Ayres has sent me with it ; and in the case of 

 some species I have also introduced a few remarks of my own, 

 which are distinguished from those of Mr. Ayres by brackets 

 and my own initials. 



249. Cypselus cafer, Licht. White-Rumped Swift. 

 Male. Iris dusky ; bill black ; toes dusky. 



I have not seen these Swifts on the coast, neither have I seen 

 them inland during the winter months; but numbers were flying 

 about Maritzburg in December, and I should have collected 

 more had I not been prevented by illness from moving at all ; 

 their flight is not nearly so rapid as that of the Black Swift ; 

 the two species were flying in numbers together, so I had a fair 

 opportunity of noticing both. 



[The ^' Black Swift" referred to in the above paragraph, is 

 the species referred to by me in the ' Ibis^ (1863, p. 321) as 

 identical with Cypselus apus. I have subsequently entertained 

 doubts as to this identity, and I await further examples to enable 

 me to compare a larger number of specimens from Natal with 

 those obtained in England. — J. H. G.] 



250. CoTYLE FULiGULA, Licht. Browu Martin. 



Male. Iris dark brown ; bill black ; tarsi and feet brown. 



These Martins are found here all through the year, but are 

 not much seen during the summer months, as they then retire 

 amongst the precipices to breed, dispersing themselves all over 

 the country in the winter j their flight is comparatively heavy 

 and slow j they are seldom seen in numbers. 



251. HiRUNDO ALBiGULA, Bp. Whitc-throatcd Swallow. 

 Male and Female. Iris dusky ; bill black ; tarsi and feet 



dusky. 



These pretty Swallows are not nearly so common as the Sum- 

 mer-Swallow {H. rustica) ; they appear to arrive at the same time 

 as the latter bird, and to leave with them, and the two species 

 are frequently seen hunting in company ; their flight is, however, 

 I think, more rapid. The tawny appearance of the breasts of 

 the specimens sent is, I believe, merely caused by their having
