colour to the rest of the undersurface. Until it can be definitely proved that 

 the large birds are not distinct I prefer to uphold the subspecies. The t3'pe 

 locality oi A. c. alexandcri is Ubangi, from which locality typical ^1. oirvirostris 

 have also been recorded. It is quite hkely that only one species exists in 

 Uganda, in which case the wing measurements would vary from 75-89 mm. 



8. Chlorocichla indicator chlorosaturata van Someren (Eastern White- tail 



Bulbul). 



<J 2, J 2. Birds from Elgon and North Kavirondo are similar to those 

 obtained in the Mabira Forest. 



9. Pycnonotus barbatus minor Hcugl. (Uganda Yellow-vented Bulbul). 

 (J 1. Met with in the foothills. 



ZOSTEROFIDAE. 



1. Zosterops iacksoni Neum. (Jackson's Ring Eye). 



<J 3, $ 4. This is the common Zosterops on Elgon. It is quite distinct 

 from Z. kikuyuensis. 



ITECTABIITIIDAE. 



1. Anthreptes coUaris hypodilla Jard. (Yellow-bellied Short- billed Sunbird.) 

 o 1, t 1- This species was equally common in the foothills and on Elgon. 



2. Chalcomitra ragazzi Salvad. (OUve Sunbird). 



cJ I, 5 2, Juv. 2. These birds are easily overlonkcd, as they keep to the 

 tops of the tall trees. Young birds are very much yellower on the undersurface 

 than female adults. 



3. Chalcomitra viridisplendens Reichw. (Blue-headed Olive Sunbird). 



cj 2, $ 1, Juv. 4. Was a fairly common species. The pectoral tufts in 

 males from Elgon are paler than those in birds from Mabira and further west. 



4. Chalcomitra acik aequatorialis Reichw. (Red-breasted Black Sunbird). 



cJ 1, 5-1, imm. 1. Fairly common in the lower country, but not met with 

 in the forests on Elgon itself. 



5. Cinnyris venustus Jalkensteini Reichw. & Fisch. ( Falkenstein's Orange- 



tufted Sunbird). 

 (a) cJ 4, (6) (J 2. (a) Four males appear to be identical with specimens col- 

 lected from Lumbwa district, B.E.A., but two others (b) are much more orange 

 on the underside and have the pectoral tufts of a deeper shade. These two were 

 collected on the plains of Bukedi on the way to Elgon, while the others were 

 collected on the foothills. The two richly coloured birds more nearly resemble 

 V, u, igneiventris (Rchw.).
