This species has a wide range on the West Coast, extending 

 from Sénégal to Northern Angola, and it is also found in North 

 East Africa. It is represented in the British Muséum by spécimens 

 from the following localities in West Africa : Sénégal, Portu- 

 guese Guinea, Gold Coast, Southern Nigeria, Cameroon, Gaboon, 

 Northern Angola, North Belgian Congo (Aruwhimi river). 



I do not agrée with Sclater and Praed (Ibis, 191 8, p. 719) in 

 considering the Sudanese birds H . s. gordoni. They appear to fit 

 the description of H. nenmaimi Rchw from Massailand. 



I agrée with Mr Sclater in considering this bird a race of 

 Hirundo semirttfa semiriifa, so that we hâve apparently three 

 geographical forms of this Swallow in Africa : 



1. — Hirundo semirufa semirufa. 



Hirundo semirufa Sund., Oefv. Ak. Fôrh., 1850, p. 107. — Type 

 localitv : « Caffraria superiore » = Southern Transvaal. 



Range. — Rhodesia, Natal, Transvaal, Orange river Colonv, 

 Matabeleland, Zambesi river District. 



Distinguishing characters. — Entire under-parts deep rufous. 



2. — Hirundo semirufa gordoni. 

 Cf. supra. 



Range. — See above. 



Distinguishing charade} s. — Under-parts pale rufous. 



3. — Hirundo semirufa neumanni. 



Hirundo neu/uanni'Rcîiw, J. f. O., 1901, p. 282. — Type locality : 

 Ssero, Massailand. 



Range. — Massailand. 



Observation. — Spécimens from the Sudan and probablv trom 

 Ruwenzori should in my opinion be referred to this form.
