10. Gypohierax angolensis (Gmel.). Vulturinc Sea- 



Eagle. 



The single juvenile specimen of this bird, which was 

 secured by Ayres at Potchefstroora in the Transvaal, was no 

 doubt an accidental straggler to South Africa, and no 

 further specimens appear to have been secured. 



The systematic position of this species appears very 

 doubtful. I have here followed Guruey in placing it next 

 to Gijpaetus, but Sclater places it between Helotarsus and 

 ilaliaetus. 



11. Circaetus fasciolatus (Gray). Banded Harrier-Eagle. 

 I have not met with this species, which appears to be a 



rare bird everywhere in South Africa. To the localities from 

 which it has already been recorded I can add Portuguese 

 East Africa, whence there are two specimens, an adult 

 female and an immature male, in the Transvaal Museum, 

 Pretoria. The adult female does not differ from Sclater's 

 description, with the exception of having white or whitish 

 tips to many of the feathers of the scapulars and lesser wing- 

 coverts, and of having the tail brownish grey, crossed with 

 four black bands. 



I have not seen a description of the young of this species, 

 so will here give a short description of the immature speci- 

 men in the Transvaal Museum. The {)lumage, especially 

 on the head and neck, is a good deal worn, and there and 

 on the breast and flanks a few feathers of the adult plumage 

 are appearing. The upper surface of the head and the back 

 of the neck are white, each feather with a fulvous brown 

 centre and a darker brown shaft-streak, while here and there 

 new dark brown feathers are appearing. Sides of face, ear- 

 coverts, chin, and throat white streaked with pale greyish 

 brown. Mantle, scapulars, wings, and upper tail-coverts 

 similar to the adult but everywhere paler brown. The 

 ti[)s of all the feathers whitish and with dark brown shaft- 

 streaks. Tail pale brown, crossed by fine dark brown bands. 

 Breast and whole of the under parts white; on the breast
