rare species am] subspecies liilberto unrepresented in the 

 British Museum, and described four new species which 

 Mr. Bates had obtained. He said : — 



I have now been able to examine cursorily the fine 

 collection of birds which Mr. G. L. Bates made on 

 his recent (1921) journey to the Genderu Mountains. 

 Mr. Bates followed much the same route as that traversed 

 by the Rigi^jenbach Expedition of 1908-1909 , except that 

 he did not proceed further north than Genderu. He col- 

 lected at Yoko, Tibati, Mbanti, Banyo, Genderu, Dodo, 

 Ribao, Kumbo, Bamenda, and Chang, most of the specimens 

 being obtained in the high plain of Tibati or in the adjoining 

 mountains. The net result of Mr. Bates's collection is 300 

 bird-skins. 



The value of this collection may be estimated from the 

 fact that the first fifteen birds I examined were all new to 

 the British Museum, i. e. : 



1. Cinnyris preussi genderuensis. 



2. Zosterops stenocricota genderuensis. 



3. Cldoroplwneus sidfiireopectus similis. 



4. Apalis i)ulclira polionota. 



5. Si/lvietta hrachyura epipolia. 



6. Bradypterus castaneus. 



7. Melociclda raentalis adamauce. 



8. Bessonornis nigriceps. 



9. Bessonornis albicapilla genderuensis. 



10. Ptyrticus turdinus harterti. 



11. Turdoides pleheius gxdaris. 



The remaining four belong to undescribed forms which

Callene batesi, sp. nov. 



S ad. Upper parts olive-brown, darker on the head ; 

 a broad white superciliary streak commencing just above 

 the eye and meeting at the base of the upper mandible ; 

 nares, eyelids, and cheeks black ; chin, throat, and rest of
