Centropus superciliosus loand^. 



Centropus superciliosus loandee Claude Grant, Bull. B. O. C. 

 vol. XXXV. 1915, p. 54 ; nr. Dalla Taudo, northern Angola. 



Generally much darker than C s. superciliosus ; top of 

 head and ear-coverts almost black, nape of neck also almost 

 black, the white streaks thus appearing much more distinct, 

 mantle and inner secondaries chestnut-brown, the latter 

 washed vrith olive. 



Type in British Museum : (J ad. Nr. Dalla Tando, 

 north Angola. 21. viii. 1908. Dr. W. J. Ansorge coll. 



Range. Angola to mouth of Congo River, eastwards to 

 eastern Belgian Congo and North-eastern Rhodesia. 



Many of the British East African, German East African, 

 and Uganda specimens are somewhat intermediate between 

 typical south Arabian birds and this race, as also are one 

 or two North-eastern Rhodesian specimens, though the 

 majority from this latter locality agree with the typical 

 west coast form. Thus, when the whole series is laid out, it 

 can be seen that a more or less gradual change takes place 

 from the east to the west, so that it does not appear that 

 any intermediate forms can be separated, but only the two 

 extremes, which differ markedly from each other in the 

 characters given. 



Centropus superciliosus sokotr^. 



Centropus superciliosus sokotra Claude Grant, Bull. B. O. C. 

 vol. XXXV. 1915, p. 55 : Adho Dimellus, Sokotra. 



Nape, sides of neck, and all the underparts much paler 

 than in C. s. superciliosus, almost lacking the strong buff 

 coloration of the typical form, which thus gives the Sokotra 

 bird a very grey appearance.
