118 Mr. C. W. Mackworth-Praed on [Ibis, 



more properly assigned. I have here kept it distinct from 

 both races, but I am inclined to think that it will eventually 

 replace F. c. hottegi Salvad. from the Lake District. Un- 

 fortunately there is only one specimen available from Lake 

 Chercher. Wing: ? 192. 

 Specimens 1. Brit. Mus. 1. 



9 B. Francolinus castaneicollis bottegi Salvad. 



Francolinus bottegi Salvadori, Ann. Mus. Civ. Gen. 1898, 

 p. 652 : Burgi in Badditu. 



Closely allied to the last race and possibly identical. It 

 appears, however, to bo brighter above and duskier below 

 than in our single specimen of the typical race. Wings : 

 S 215-232; ? 192-196. 



Specimens 9. Tring 9. 



Range. Badditu and Djam-Djam on the south-eastern side 

 of the Abyssinian Lake District. 



9 c. Francolinus castaneicollis, subsp. 1. 



This is the other race to which the name ' castaneicollis ' 

 may possibly apply. It differs from the Badditu birds by 

 having less white marking on the back, and the upperside is 

 generally duskier and less brown, while the chestnut of the 

 neck is somewhat paler. Wings : S 220-228 ; ? 188-198. 



Specimens 4. Brit. Mus. 4. 



Mange. Harar district eastwards, where it merges into the 

 next race. 



9 D. Francolinus castaneicollis ogoensis Praed. 



FrancoUims castaneicollis ogoensis Praed, Bull. B. C. xl. 

 p. 141 : Sheikh Pass, Ogo, British Somaliland. 



Differs from all other races of F. castaneicollis by the 

 pronounced greyness of the upperside, the feathers of the 

 mantle being paler and the chestnut of the neck duller, 

 almost grey-brown. Wings : c? 212-222 j ? 188-192. 



Specimens 14. Sir G. F. Archer 6. S. P. (/larke 6 (type). 

 Tring 2. 



Range, British Somaliland.
