The length of wing of the male is 94 mm. and that of 

 the female 92 (93) mm. This measurement of the male is 

 equal to that which Oberholser has recorded as maximum 

 for his subspecies »micrus», to which he ref ers the East Afri- 

 can Bulbuls of this group. As I have mentioned at another 

 opportunity this maximum is often exceeded. I have myself 

 obtained a specimen from Juja with the length of wing 95 

 mm. For the Bulbuls of the western portion of Brit. East 

 Africa Mearns has created another subspecifie name »fayi». 

 This is said to be more darkly coloured than »micrus», and to 

 have an average length of wing of 94,3 mm. in the males and 

 88,2 in the females. On the material which I have seen it 

 appears very difficult to maintain these subspecies, as speci- 

 mens from the same place vary somewhat in colour as well 

 as in size. But I cannot find any constant difference in co- 

 lour between specimens from Escarpment, Nairobi, Juja and 

 Kilimanjaro when their plumage is in the same state of 

 wearing or freshness.
