FALCOITIDAi:. 



1. Polyboroides typicus Cab. (Bare-faced Whistling Hawk). 

 (J 1 . A single very dark specimen was obtained. 



2. Kaupifalco monogrammicus Temm. (Lesser Barred Hawk). 



(J 1. Common. I can find no description of the first or second plumages 

 of this bird, nor have I ever obtained a specimen in either of these plumages. 



3. Astur melanoleucus Sm. (Pied Sparrowhawk). 



(J 1. A nice clean specimen in full breeding dress. They are not very 

 common. 



4. Astur tachiro Daud. (Barred Sparrowhawk). 

 <J 1. One specimen in full dress was procured. 



5. Micronisus gabar Daud. (Lesser Barred Sparrowhawk). 



S I, S immat. Tliis is one of the commoner hawks. If the black birds, 

 hitherto known as M. niger Bonn., are nothing more than melanistic forms of the 

 grey bird, it is interesting to note that they are comparatively common, also

6. Astur sphenui'us Riipp. ^RiippeU's Sparrowhawk). 

 9 1. A female in the second immature diess.

 dirty white ground, indistinctly mottled with bro^vnish.

 (J 2, 9 1. A very common species. 



9. Baza verreauxi Lafr. 



10. Baza emini ? (Cuckoo Falcon). 



cJ 1, ? 1. I have before me an interesting series of birds, showing four 

 distinct phases of plumage. 



In the fuUy adult bird, the under wing-coverts are a bright red-brown, 

 uniform. The barring on the flanks is of the same colour, thvis agreeing with 

 B. emini. 



In specimen 2 the coverts are white with red-brown bars, while the flanks 

 are barred with dark brown. 



Specimen 3. Under wing-coverts uniform pale sandy brown, and the under- 

 surface of the body barred with light and dark brown and with a few blackish 

 droplet spots. 



Specimen 4. Under wing-coverts white or creamy uniform, the whole of
