The general colour of the upper parts varies from a rich russet- 

 brown, darkest on the head and palest on the rump ; in spring and 

 autumn plumage to a faded earthy browu, with little or no russet 

 le''t except on the rump in summer and winter ; eye-stripe nearly 

 obsolete ; quills and tail-feathers a darker brown than in the pre- 

 ceding species, but the variations in the detail of their coloration, 

 as well as those of the underparts, the same ; the bill the same as 

 in the last species, but the legs, fe 't, and claws darker, pale ash- 

 colour. Length of wing 2-48 to 2-18 inches, tail 2-2 to 2-0, culmen 

 0-67 to 0-6. Third and fourth primaries nearly etjual and longest ; 

 second primary equal to the seventh, sometimes a trifle shorter, 

 sometimes a trifle longer. 



This species is an African form of the preceding, and differs from 

 it only in having tlie upper parts of a more decided coffee-brown, 

 and in being slightly smaller in size. 



The South-Afric;m Eeed-Warbler appears to be confined to 

 Central and South Africa, breeding in the Transvaal and Damara 

 Land, and probably remaining there during the whole year. Hart- 

 laub's bird from Lado, Central Africa, appears to be a partial albino 

 of the species.
