to the colour of the back and scapulars. In some specimens 

 these parts are very similar to those of the Kilimanjaro 

 birds, in another the black mottling of the central band is 

 quite dominant över the somewhat brighter rufous chestnut, 

 in still another the central band may be termed black with 

 a rufous chestnut shaft streak and more or less mottlings 

 of the same kind. The edges of the feathers are grey and 

 the intermediate parts display various shades of brown in 

 different birds. In still another bird even the new feathers 

 have the central band rather dull rufous brown, mottled with 

 black, and the greater part of the lateral portions of the 

 feathers are grey. 



The Escarpment Francolins have the central bands of 

 the feathers more coarsely and more conspicuously mottled 

 with black, and the edges of a purer grey, but are other- 

 wise rather similar. 



The rump of the Kilimanjaro birds are rather a dark 

 shade of »auburn», vermiculated with black, than »vandyke 

 brown». In the darkest of the birds from Donya Sabuk the 

 colour of the rump is very similar to that of the Kiliman- 

 jaro birds, but although it varies very much in different 

 shades of brown, approaching »proufs brown» and »snuff 

 brown» it cannot be termed »olive brown» in any of the 

 present specimens. 



The mottling of the outer web of the primaries is not a 

 constant characteristic. It might be traced on the extreme 

 edge of some inner primaries in one of the Kilimanjaro birds, 

 but not in the other. It is also absent in most of the birds 

 from Donya Sabuk, but present in one or two. 



The rectrices of the Kilimanjaro bird are very dark 

 brown, transversely vermiculated with »snuff brown». The 

 rectrices of the Frankolins from Donya Sabuk are vermicu- 

 lated with blackish and various shades of brown from »snuff 

 brown» or »cinnnamon brown» to »cinnamon rufous», or even 

 dull buff. The Escarpment birds agree with the darker of 

 the former group. 



The feathers of the chest are in all the birds provided 

 with a more or less pronounced, dark central band which 

 deepens to a darker apical spöt, and the sides of the feathers 

 are lighter in hue. The spöt is in the Kilimanjaro birds 

 perhaps most similar to »bister» and the sides of the fea-
