Tins is a South- Afi-ican bird, and, altliongli it is a common and well-known species, there 

 still remains a great want of knowledge as to its migrations. It was not exactly described 

 till 1R40, thoLio-h many authors believe that Levaillant's plate of the ' Hirondelle h front 

 roux ' was intended for this species. On this plate Vieillot founded his name of Hirundo 

 rujifrons, a title frequently adopted for the species ; but the figure is so inaccurate and is 

 so much more like that of the Common Chimney-Swallow, that it is impossible to admit 

 it as a representatiou of //. albigularis. 



As will be seen from the notes quoted below, the present species occurs iu South 

 Africa iu August, breeds in September, October, and November, and leaves for the nortli 

 along ^^•ith the European Chimney-Swallow (//. ruslica) ; but where it winters is at 

 present unknown. Drs. Tischer and Pteichenow record a specimen from jMalindi, in 

 East Africa, in June, and as they mention //. ccthiopica at the same time and from the 

 same place, we may take it for granted that the ranges of both species unite on the east 

 coast of Africa, and that it is here that //. albigularis probably winters.
