The general colour of tbis bird is fox-red, witb well-defined 

 blackisb spots along the shafts of the feathers. The tail is some- 

 what darker superiorly, with from eighteen to twenty narrow 

 inconspicuous cross-bands on the shafts of the rectrices. The 

 last of these cross-bands is not conspicuously broader and better 

 defined than the next to it, and there is no lighter edge at the 

 extremity of the tail. The lower coverts of the wings are scarcely 

 lighter than the body, and each feather has a dark spot on the 

 shaft ; the inner barbs of the primaries and secondaries are 

 whitish at the roots. The soft parts are greenish yellow ; the 

 bill and claws are bluish, the base of the lower bill yellowish, the 

 iris brown. 



I discovered this bird, which is easily distinguished from all the 

 other species of Tinnunculus, during my sporting excursions into 

 the countries on the Upper Nile. With regard to its proportions, 

 it is intermediate between F. tinnunculus and F. rupicoloides, but 

 is more slender and has the wings longer than either of them.
