up in tall trees creeping alonj^: the boughs like a Nuthatch. 

 It keeps up an incessant twittering note. 



Camaroptera sundevalli Sharpe. 



Camaroptera sundevalli Stark, ii. p. 113. 



Camaroptera griseoviridis sundevalli Reich, iii. p. 618. 



a. S. Lake Ngami, 2700 ft., 28th June. (No. 48, 

 i?. B. W.) 



Iris hazel ; bill dark horn-coloured ; feet brown. 



SundevalFs Bush- Warbler was not seen in the Kalahari, 

 but in Ngamiland it was plentiful. I could find no difference 

 between the notes and habits of this species and those of 

 C. griseoviridis from Uganda and the Congo. Its note is 

 exactly like that of the Common Stonechat and its habits 

 like those of the Common Wren. 



Eremomela flaviventris (Burch.). 



Eremomela jiaviventris Stark, ii. p. 106 ; Reich, iii. p. 634; 

 Ogilvie-Grant, Bull. B. O. C. xxv. pp. 120, 121 (1910). 



a, 6. c? ? • Molopo River, 3000 ft., 19th April. (Nos. 14, 

 15, R. B. W.) 



Iris hazel ; bill and feet blackish. 



The range and synonymy of this species will be found 

 fully discussed in my paper quoted above. 



The Yellow-bellied Bush-Warbler was only seen on the 

 Molopo River, and is apparently an uncommon bird. Its 

 habits do not differ, so far as I have observed them, from 

 those of other members of the genus. 



Eremomela usticollis Sund. 



Eremomela usticollis Stark, ii. p. 109 ; Reich, iii. p. 641. 



a-c. S ? . Molopo River, 3000 ft., 12th April. (Nos. 7, 

 8, 12, R. B. TV.) 



d-f. S 2 . Lake Ngami, 2700 ft., 8th July. (Nos. 55, 

 56, 57, R. B. W.) 



Iris pale yellow ; bill and feet light brown. 



Generally speaking, examples from the Transvaal are 

 rather more strongly marked with buff on the breast and 

 belly than those from Damaraland, but the difference is not 

 constant, and the western birds ought not to be separated,
