Type in the British Museum, J ad. B.M. Reg. No. 

 1911. 4. 26. 2. Ashanti, Gold Coast. H. G. F. Spurrell coll. 

 Number of specimens examined : 37 ad. c? ? of new race ; 

 39 ad. c? ? of typical form. 



Range. Represented in the British Museum from Sierra 

 Leone, Gold Coast, and S. Nigeria. 



Observation. C. svperhus superhus was described from 

 Malimbe on the Loango coast. It extends from Cameroon, 

 Gaboon, and N, Angola through the Belgian Congo into 

 Uganda. I can see no difference between birds from East 

 and West Africa. 



Cyanomitra oritis bansoensis, subsp. no v. 



Adult male. Differs from C. oritis oritis (which is confined 

 to Cameroon Mountain) in having a shorter bill (25-26 mm. 

 as against 28*5-30 mm.) and a slightly shorter wing. The 

 metallic feathers of the crown and sides of the neck are steel- 

 green, instead of steel-blue, and the metallic feathers of the 

 throat and breast are steel-blue, instead of deep purplish 

 blue. The anderparts are rather brighter and the middle of 

 the belly is ytdlower. 



Type in the British Museum, ^ ad. Banso Mts., North of 

 Kumbo, Nigerian-Cameroon Highlands, 6000 ft., 26 Sept., 

 1921. G. L. Bates coll. 



Range. Hii^hlands of Nigeria and Cameroon (Tibati, 

 Kumbo, Banso Mts , Manenguba Mts.). 



Observation. The possibility of the Manenguba Mountain 

 Sun-bird belonging to a distinct race was foreshadowed by 

 me in ' Il)is,' 1915, p. 654. The specimens now obtained 

 l)y Mr. Bates have decided the question. 



A new race of Red-tailed Chat was also described 

 by Mr. Bannerman from the Cameroon Highlands, as 

 follows: — 



Cercomela familiaris genderuensis, subsp. nov. 

 Adult male. Most nearly allied to C f. gumhag<i' Hartert, 

 but darker throughout, particularly on the crown and mantle.
