nomenclature of tliis jjjroup, most of which has I)een cor- 

 rected by Neumann, J. f. O. 1914, pp. 36-39. Tliis species 

 also has a rufous, or partially rufous^ phase in dry countries, 

 e.<j., soutli-Avest Africa, Somaliland, and in the White Nile 

 district. This red phase was confused by Sharpe, Ibis, 

 1898, p. 289, and referred to by O.-Grant, Ibis, 1902, 

 p. 438, as Bubo ubyssinicus (Gnerin). This is, liowever, a 

 strikingly distinct species o£ Asia and has no connection 

 with this group. 



The races of this species are : — 



1. B. a. africanus Temm. South Africa to Angola and 



Nyasaland ; East African and Uganda birds are 

 intermediate with the next form. 



2. B. a. cinerascens Guer. N.W. & N.E. Africa and 



the Sudan. 



3. B. a. milesi Sharpe. S. Arabia. 



It seems possible that Asio tnnculosus amerimnus 

 Oberholser, P. U.S. N. M. xxviii. 1905, p. 856, Durban, 

 may have to be recognized as a paler, greyer race which 

 extends to British East Africa, but there is such variation 

 in the large series in the Museum that for the present we 

 prefer to unite it with the typical race. 



Bubo lacteus.

There do not appear to be any recognizai)le races of this 

 Owl, though there is much individual variation in size and a 

 certain amount in coloration. On the whole, south African 

 birds are large, as are Abyssinian, and north-west African 

 and east African are smaller, while Nyasaland and Uganda 

 birds are darker in colour.
