Natural History of South Africa, fyc. 15 



transversely with black and white, each feather besides with 

 one or more broad pure black transverse bands, and the lateral 

 ones with broad white tips ; armillse white. Bill horn colored 

 towards tip, yellow towards base ; legs and toes yellowish ; 

 claws horn colored. Length from bill to tip of tail nearly 

 eighteen inches. 



This species is closely allied to the Otis Afra, or black 

 Koran of the Colonists, but is at once distinguishable from it 

 by the white markings of the inner vanes of the primary quill 

 feathers. Its cry is also very different, being simply kir re- 

 peated many times in quick succession. I have never found this 

 bird within the limits of the colony, but have seen many of 

 them on the Bushman flats towards the Orange River. From 

 the last circumstance, they are known to the farmers of the 

 northern frontier by the name of " Bushman Koran*." 



* Many interesting species of this genus have already been discovered in 

 South Africa, and doubtless the catalogue will yet be extended when more 

 attention is devoted to the examination of the individual characters of birds. 

 The species at present known to us are Otis Arabs. Cuv. Kuif kop Peauw. 

 Otis ruficolUs. Cuv. red necked Peauw Otis Cokii. Smith mms. black 

 throated Peauw. Otis Afra. Lin. blackKoran. Otis Torqiiata. Cuv. brown 

 Koran. Otis Vigorsii Smith mms. Karoo Koran. Otis veroxii Smith mms. 

 blue bellied Koran. Otis Afroides Smith. Bushman Koran.
