This bird inhabits the same kind of locality as the prece- 

 ding and is therefore very difficult to detect. Certainly there 

 are many excellent songsters among the Pycnonotidae but, in 

 my opinion, none can match this one, which is the finest master- 

 singer 1 have heard among African birds. Like some of those 

 mentioned previously he sings even after nightfall. 



Wing 69 mm.; tarsus 23 mm. 



Irides dark red; bill dark greyish brown; legs bluish grey. 



Grote mentions the finding of this bird in Usambara and 

 gives the measurement for the length of wing as 66 — 67 mm. 

 He is unable to find any difference between these specimens 

 and others from Kikuyu and Kilmanjaro (J. f. 0., 1921, p. 137).

A by no means rare bird in the highland districts, occurring 

 everywhere on the bush-clad slopes and in the less dense forests. 

 It was found on Elgon up to an altitude of 8500 feet. Schuster 

 has described this bird's song very carefully and also gives some 

 information about the occurrence of the bird. 



In the present series there are no great differences. Younger 

 birds are more olive-brown above than older, which are predo- 

 minantly slate-grey.

On Elgon this bird was found in about the same kind of 

 locality as the preceding, although it does not seem to be common.
