Hab. North-Eastern Africa (Heuglin); Gold Coast (Pel); Old 
Calabar (Jardine); Gaboon (Verreaur); Camma River (Du Chaillu); 
Damara Land (Andersson); Cape Colony (Layard, Surtees); Natal 
(Ayres). 
The few references given above are some not included in the other- 
wise very complete list of synonyms given by Dr. von Heuglin in his 
work on the Birds of North-Eastern Africa. To the account given 
by myself and Mr. Dresser (anted, p. 244) I cannot add anything. I 
think, however, that there cannot be the slightest doubt that the 
bird supposed to be Hirundo cahirica by ornithologists, from West- 
ern Africa, is only H. rustica shot in full spring plumage on its way 
northwards.
