was doubtless subsequent to the date of the note above recorded. 

 This species has not as yet been figured. In the English names

This Falcon (called in Damara Land "Onikothe") is to 

 be met with from the Cape Colony in the south to the 

 Okavango River in the north, and as far eastward as

 and sweeping flight.
