This Cliff-Swallow was discovered by Senhor Anchieta at Caconda in Benguela. It is a 

 very distinct species, and cannot well be confounded witb any of the other members of 

 the genus. 



The description is copied from the British Museum ' Catalogue of Birds ' ; it is there 

 taken from the original specimen lent us by Professor Barboza du Bocage. The figure 

 is drawn from the same bird.
