Birds from Eastern Africa. 125 



The bill appears to have been darkish horny black, orange 

 at the gape ; and the bare patch before and behind the eye 

 orange-red. 



Wing 7'5 inches, tail 2'8, tarsus 2'4. 



The specimen here described was collected by Mr. Gedge, 

 Mr. Jackson's colleague, in whose honour I have named it. 



It is labelled as follows : — 



" (J . Elgon-plains. Legs brown in front, reddish brown 

 behind. Irides dark brown. 2. ii. 90.''^ 



This Francolin belongs to the group containing F. clapper- 

 toni and F, rueppelli, and most probably F. hartlaubi ; but I 

 have never seen a specimen of the last-named species, which 

 was described from an immature male obtained at Huilla, 

 W. Africa. From the description, however, it would appear 

 that F. hartlaubi is closely allied to the first two as well as 

 to the present species. All these Francolins belong to a group 

 characterized by having the outer webs of the outer primaries 

 (which are dark brown) margined, on the terminal half and. 

 barred on the basal half with buff, and either the terminal 

 part of the inner webs almost entirely buff, as in F. clapper- 

 toni and F. gedgii, or largely barred and marked with that 

 colour, as in F. rueppelli and F. hartlaubi. Every feather of 

 the breast and underparts is dark brown, margined with 

 buff. 



These four species may be distinguished as follows : — 



I. Back of the neck arid mantle olive-brown or dark 

 brown, margined with white or pale buiF. 

 A. Feathers on the chest buff, with a wide brownish- 

 black stripe down the middle. Terminal part 

 of the inner webs of the inner primaries buff. A 

 patch of black feathers above the gape. 

 a. Top of the head and ground-colour of the 

 upper parts reddish or olive-brown ; feathers 

 of the mantle widely margined all round with 



whitish buff F. clappertoni. 



h. Top of the head and ground-colour of the rest 

 of the upper parts rich dark brown ; the 

 feathers of the mantle narrowly margined 

 on the sides with white F. yedyii.
