A race of S. xanthogaster bas been described from the Mabira 

 forest, Uganda, and ranges into the N. Belgian Congo, it must 

 stand as : 



yi. — Stiphrornis xanthogaster mabirae. 



Stiphrornis mabirae Jackson, Bull. B. O. C, XXV, 1910, p. 85 : 

 Mabira forest, Uganda. 



Range. — Uganda forests, Congo forest, North Belgian Congo 

 (Poko). 



Distingjnshing characters . — Distinguished from S. x. xantho-

 on breast deeper. 



Prima mistacea melanorhyncha. 



Drymoeca melanorhynchus ]akd. anà Frxs,., Contr. Orn., 1852, 

 p. 60. — Tvpe locality : Abomey, Dahomey. 



Three. examples of the Coastal Tawny-flanked Wren-warbler 

 were shot by Mr Lowe at Iju, in December and January; and 

 Mr Kemp obtained a pair at Agoulerie in June. 



P. m. melanorhyncha was described from Dahomey and we 

 hâve examples of this dark coastal race from Portuguese Guinea, 

 Sierra Leone, Libéria, Gold Coast, Dahomey and Southern 

 Nigeria. 



The races of P. mistacea hâve recently been worked out by 

 Messrs Sclater and Praed (Ibis. 19 18, pp. 676-677) and I follow 

 their conclusions. They recognise four races ail of which occur in 

 Western Africa, 



The coastal birds from Portuguese Guinea to Southern Nigeria 

 must be assigned to P. m. tnelanorhyncha.
