with at Esamesa and Hityc on the River Ja, Cameroon, 

 1500-2000 ft. A female was also procured by the late 

 Boyd Alexander at Angn on the Welle River (about 

 Lat. 2i° E., Long. 4° N.).

Apalis ansorgei, sp. n. 



Adult male. Near A. nigrescens Jackson^ and, as in that 

 species, the four outer pairs of tail-feathers are white, but 

 the crown and upperparts are grey tinged with brownish, 

 instead of deep brown. Iris light red ; bill black ; feet 

 burnt-sienna. Wing 48, tail 50 mm.

Apalis rufigular is (Fraser). 



Sharpe has already pointed out in 'The Ibis,' 1908, p. 320 

 that his Euprinodes leucogaster (1904) is synonymous with 

 E. schistaceus Cassiu (1859) ; also that E. olivaceus (Strickl.) 

 (1844) is founded on young examples of E. rvfigularis 

 (Fraser) (1843). He did not, however, suspect that 

 E. schistaceus and E. rufigularis were respectively the male 

 and female of one and the same species. 



All the adult grey-throateii specimens before us, eight in 

 number, are males, and there are several immature examples 

 marked as males which have grey feathers making their 

 appearance on the throat. 



All the rufous-throated specimens, sixteen in number, are 

 females with the exception of three, viz., two from Fernando 

 Po collected by E. Seimund and Boyd Alexander respec- 

 tively, and one from N'Dalla Tando, northern Angola, 

 procured by W. J, Ansorge. I believe that in these three 

 instances the sex has been incorrectly determined and have 

 little doubt that the grey-throated and red-throated birds 

 are of one species and should be known as A. rufigularis 

 (Fraser), that being the oldest name. Mr. Bates is certainly 

 of this opinion {cf. ' Ibis,' 1911, p. 616).
