This species is by no means uncommon in Southern 

 Damara Land, and it also occurs in the parts adjacent ; 

 it confines itself to dense thickets or low bushes, where 

 it hops about incessantly, flitting rapidly from twig to 

 twig, and passing out of sight directly you have caught 

 a glimpse of it. It is generally found either singly or 

 in pairs. 



Two nests of these birds, which I found in the month 

 of January, were composed of stalks of plants loosely 

 put together and lined with stalks of a softer kind. One 

 nest was placed very low in a low bush, the other about 

 5 feet from the ground in a thorn bush ; each nest con- 

 tained three eggs. 



The iris in this species is purplish, with a narrow 

 greyish ring round the pupil ; the bill is black ; the 

 legs and toes brownish lead-colour. . 



[In the present as in the preceding species some differences of 

 size are observable between different individuals ; but the average 

 measurements are decidedly less than those of the preceding 

 species, as will be seen by the following Table, for the materials 

 of which I am again chiefly indebted to the kindness of Mr. R. 

 B. Sharpe.
