274 FALCONID^ PALCO 



Distribulion. — Africa, south of the Sahara from the Gambia river 

 on the west and Shea on the east southwards. In South Africa it 

 appears to be an exceedingly rare bird. The type was obtained by 

 Sir Andrew Smith on the banks of the Kei river in the eastern half 

 of the Colony. There is a young specimen from the neighbourhood 

 of Durban, obtained in February, preserved in the South African 

 Museum, but beyond these two I know of no other recorded 

 localities in South Africa.
