Besides having the middle pair of tail-feathers more olive- 

 brown and much less rufous than in S. vulpina Reich., the 

 present species has the inner web of the fourth pair of tail- 

 feathers black almost to the tip and that of the fifth (penul- 

 timate) pair black on the basal half. In S. vulpina the 

 fourth pair of tail-feathers have only the basal portion of the 

 inner web next to the shaft blackish, while the two outer pairs 

 are uniform pale chestnut-red. It will thus be seen that the 

 ranges of the West-African S. fraseri and of the East Central 

 African /S. vulpina overlap on the Upper Congo. 



Whether the genus Stizorhina is really distinct from Neo- 

 cossyphus requires careful consideration, S. finschi (Sharpe) 

 and iV. pr(Epectoralis Sharpe being almost alike in plumage 

 and differing chiefly in the shape of the bill, which is stouter 

 and more flattened in the former.
