Interraediate between S. natahnsis and S. africanus, but closer 

 to africanus, in that the black markings on tlie sides of the body ; 

 are veiy distinct , tboug'h fewer in number and smaller than in < 

 the Cape-Colony form. But the upper and under tail-coverts are 

 without dark central stripes.

Very similar to S. africanus, but differs in the almost uniform 

 rufous-buff colouring of the under surface of the body, and in 

 the absence of black shaft-stripes to the upper and under tail- t 

 coverts ; the sides of the upper ehest and crop, in some specimens, 

 are sligthly niottled with the dark tips and central stripes to the 

 feathers, but show no distinct black marks ; the flanks are generally 

 entirely uniform, but in one specimen find a few obscure dark 

 central stripes to some of these feathers ; the upper and tail coverts 

 are always uniform. \ 



Hab.: Natal. \ 



(The autor regards it as merely a well marked local race of | 

 S. africanus).

Ad. Very similar to Thr. castaneus, but deeper chestnut below, 

 without the black cross bands of the last-named species ; the white 

 on the throat confined to the throat itself and not extending to 

 the fore neck.
