LUSCINID^. 101 



I observed this Sylvia sparingly in the neighbourhood 

 of the Okavango and in Damara Land ; it is migratory 

 and amongst the earher arrivals. It sings deliciously, 

 and is found in small flocks hopping about industriously 

 amongst the branches of the smaller trees, preferring 

 such as have a thick tangled foliage, which it slowly 

 examines for small insects and larvse. 



The iris is brown, the legs and toes slate-coloured ; 



the gape melon-yellow; the upper mandible brownish 



with yellowish tip and edges, the under mandible yellow 



tinged with flesh-colour ; the ring round the eyes light 



yellow. 



[Mr. Andersson's last collection contained specimens of this 

 Warbler^ which appeared to be identical with European examples.

I have only observed this species in the neighbour- 

 hood of the Okavango ; it is rather lively in its habits, 

 hopping incessantly amongst the foliage, and even 

 suspending itself head downwards from the buds and 

 flowerets of the trees, almost every part of which it 

 explores in search of the small insects which constitute 

 its food. 



The irides are very dark brown, almost black ; the bill 

 brownish, lighter beneath and tinged with yellow ; the
