100 Dr. F. E. Stoehr and Mr. W. L. Sclater on 



rocks were very steep, they had a pretty habit of taking long 

 jumps down-hill, perfectly motionless like a diver, but feet 

 foremost, with the wings closed until just before reaching the 

 ground^ when they would open them to break the fall,

We found Arnot's Bush Chat very common at a spot on 

 the Anglo-Portuguese boundary in very dry mopani veld, 

 some four miles from water. I have since seen it twice, 

 both times in dry country, and it is plentiful on Ulungu 

 Hill. They eat small insects, particularly ants, which they 

 find partly on the ground, but also, at some seasons, on 

 the bark of trees. Sometimes they perch on a dead branch 

 and take insects in the air, in much the same style as a 

 Drongo. The females have a varying amount of grey or 

 white extending from the throat on to the breast.

Heuglin's Robin Chat inhabits thick woods near water. 

 I rather suspect it of the song ascribed to Lagonostida niveo- 

 guttata (Peters' Ruddy Waxbill).
