"Found the Pale Swift much less common th.an in Fiieileventura. 

 It was only seen in any numbers at Tihosa, though single birds 

 were seen from time to time during my journey in 1913." 

 (Bannerman, Ibis, 1914, p. 252.)

Outer hlets. 

 Montana Clara. 



A few were noted which appeared to be breeding in holes of the 

 sea-clitfs, 1913. (Bannerman, Ibis, 1914, p. 77.) 



Allegranza . 



"I saw three birds in this islet on the 23rd of June, 1913." 



(Von Thanuer, Orn. Jahrb. 1913, p. 192.) 

 " A few birds were seen by my taxidermist between the 9th and 



14th of June, 1913." (Bannerman, Ibis. 1914, p. 86.) 



Range beyond the Archipelago. 



Bielira's Pale Swift is also foiuid in Madeira and in parts 

 of north Africa (Morocco, Algeria, and Tunisia), where it is 

 resident. 



I have examined the following skins amongst others, 

 which are particularly worthy of notice here, in the Triiig 

 Museum ; — 



Cape Blanco (Mazagan), Morocco. 20. i?. 02. 



Biskra. 22. iv. 09. 



„ 25. iii. 09. 



Algiers. 8. v. 11. 



Mogador. 19. iv. 04. 



Bale du Levrier, Cape Blanco. 7. v. 95. 



Omaruru (Damaraland). 12. xi. 79. 



In the British Museum there are only two skins from the 

 mainland which have been identified as belonging to this 

 subspecies : — 



a. Beuguella. jS'o date. 



h. Damaraland. 2 December. 



I am very doubtful whether the Benguella skin is really 

 a specimen of this Swift. Its colouring appears to me 

 too brown. Wiiere the bulk of the Canaiiau birds go to in 

 October, November, and December it is impossible to say.
