5. Francolinns sephsena. 



Under this heading come a large group of Francolins 

 which extend over most of southern and eastern Africa. 

 They show considerable local variation, and as in many 

 groupSj the names bestowed on them in various places do 

 not by any means correspond to the most clearly marked 

 differences of plumage. They appear to be best grouped as 

 follows : — 



5 a. Francolinus sephsena sephsena (Smith). 



Perdix sephcena Smith, Report Exp. Centr, Africa, 1836, 

 p. 55 : Marikwa, i. e. Marico Kiver, Transvaal. 



Francolinus pileatus Smith, Illustr. Zool. S. Africa, 1838, 

 pi. 14 (renaming of above) . 



The largest race of the group. Wings: c? 162-172; 

 ? 156-162. There is one remarkably small specimen in 

 the Tring Museum, a male with a wing of 156. 



Specimens 18. Brit. Miis. 11 (type). Tring 7. 



Range. Transvaal, Bechuanaland, Lake Ngami, etc. 



5 b. Francolinus sephsena zanihesiae. 



Francolinus sepluma zamhes'ur Praed, Bull. B. 0. C. xl. 

 1920, p. 140: Mesanangue, Zambesi River. 



Very like preceding race in colour, but smaller. 



Wings: c? 153-159; ? 148-155. 



Specimens 8. Brit. Mus. 8 (type). 



Range. Zambesia, i.e. inland and northern Portuguese 

 East Africa and the adjoining parts of Rhodesia. 



5 c. Francolinus sephsena, subsp. 1 & 2. 



There are two birds at Tring and one in the British 

 Museum from the South-West African Protetorate, and 

 they differ considerably from one another. I am inclined to 

 think that more material will show that there are two races 

 in that part of Afiica, a northern extending into Angola, 

 and a southern from Damaraland. 



These southern races of F. sephcena all stand apart from 

 the eastern and north-eastern forms in that the breast is 

 spotted and not only the neck.
