This species is most nearly allied to S. flaviventris Sharpe, from which it differs 

 chiefly in being somewhat larger ; in having both mandibles entirely black ; the back 

 dark olive without any brownish tinge ; the feathers surrounding the eye and on the 

 cheeks whitish with black tips, giving these parts a distinctly spotted appearance; the 

 chest and breast dull olive-green and the belly and rest of the underparts pale yellow. 

 Iris hazel ; bill black ; feet reddish-brown. Total length about 3 inches ; wing 2 ; 

 tail 0'75 ; tarsus 0"66. 



This species ranges to the Southern Cameroon, whence it has been described as 

 S. batesi.
