An examination of the material in the Museum leads us 

 to the conclusion that there are four distinguishable races of 

 this Sunbird : — 



1. C. V. VERTicALis (Lath.), the type-locality of which 

 should doubtless be fixed at Senegal. Back more golden 

 olive-green. Metallic colour of head rather more blue than 

 green. 



Distr. From Senegal to Gold Coast Colony. 



2. C. V. CYANOCEPHALA {Cevthia cyanocephala Shaw, Gen. 

 Zool. viii. 1811, p. 203 : Loango). Back rather darker and 

 less golden ; metallic colouring the same. 



Distr. Cameroon to Gaboon, Angola, and North-western 

 Rhodesia. 



3. C. V. viKiDisPLENDENs (Rcichw.), V. supi'ii. Back a 

 duller olive-green; metallic colouring rather more green 

 than blue. 



Distr. From the southern Bahr el Ghazal through the 

 Lake districts and the eastern part of the Belgian Congo. 



4. C. V. ALiN^ Jackson, Bull. B. O. C. xiv. 1904, p. 94 : 

 Ruwenzori. 



Back much brighter than either of the others with 

 almost a rufous tinge; metallic colour deeper blue, and 

 underparts considerably darker and pectoral tufts deeper 

 yellow. This is a mountain-iace confined to the slopes of 

 Ruwenzori above 5500 ft. C. v. viridisplendens is found 

 on the slopes below 6000 ft., so the subspecies must meet 

 in this region. The two forms are so distinct that it is 

 probable that they do not interbreed, in which case they 

 should be regarded as distinct species. 



We have found no bird exactly answering to the descrip- 

 tion of C. V. tanganjicce Reichw. (J. f. O. 1915, p. 128).
