The distinction between this species and C. apus was first 

 pointed out by Capt. Shelley, and described in * The Ibis' (1870, 

 p. 445) . He says it is extremely abundant in Egypt, and arrives 

 iu February, and that he never saw the common Swift, though 

 he kept a sharp look-out for it. My specimens from Madeira 

 and the Canaries agree with his Egyptian types. It is easily 

 distinguished on the wing, by its much lighter colour and whiter 

 throat. It is rather remarkable that in Madeira both this and 

 the next species are said to be stationary throughout the year, 

 while in the Canaries they leave in autumn and return in March. 

 C. paUidus appears usually a few days before C. unicolor. It 

 breeds, both in the Canaries and Madeira, in cliffs.

This appears equally common with the last-named species, 

 both in Madeira and the Canaries, where it frequents chiefly the 

 high land, while its congener is most abundant near the sea, 

 whence the latter has received the name of '^Andorhina do 

 mar," while the former is called "Andorhina da serra." I saw 

 several about the Canadas, skimming over the retama bushes, 

 which were then in full bloom and attracted numerous insects. 

 It builds in holes in the cliffs, where it nests in societies. I 

 also found a small colony nesting in a cliff on the north side of 

 Madeira, not far from the sea.
