in the Lydetiburt/ District of Transvaal, 427 



[This specimen^ which is only the second that I have seen, 

 has been added to the collection at the British Museum ; it 

 agrees closely with the type figured in 'The Ibis^ for 1864, 

 pi. ix.— J. H. G.] 



20. Petrocincla rupestrts (Vieill.). South - African 

 Rock-Thrush. 



These birds were scarce at the Gold-fields, though a few 

 were scattered about in our locality ; they are fond of climb- 

 ing low rocks and stones on the slopes of the mountains, and 

 are pretty conspicuous on the tops of the stones, though very 

 shy. 



21. CossYPHABicoLOR(Sparrm.). Vociferous Chat Thrush. 

 Exceedingly scarce in the Lydenburg forests ; I only saw 



two or three during my stay. They seem to prefer the skirts 

 of the woods and bushy places to the more timbered parts. 



22. Andropadus flavostriatus, Sharpe. Yellow-streaked 

 Bulbul. 



These Bulbuls are to be found, nearly always, in small com- 

 panies, making much noise amongst the dry leaves on the 

 ground as they hustle them about in search of food. On the 

 approach of an intruder they make an incessant chattering, 

 which immediately attracts attention ; and were it not for 

 this habit, they would not often be noticed in the dense bush, 

 which they are fond of frequenting. 



The woods would often be utterly silent but for the noisi- 

 ness of these little fellows. 



Male. Total length 8| inches, tarsus l-^, bill 1, wing 3|, 

 tail 3f , iris hazel, bill black, tarsi and feet ashy. 



Female. Total length 7f inches, tarsus 1, bill |, wing 3|, 

 tail 3 j iris tawny, bill dusky, tarsi and feet ashy. 



23. Andropadus iMPORTUNUS (Vieill.). Sombre Bulbul. 



A very silent bird, moving quietly about amongst the tops 

 of low trees and bushes, and feeding much on fruits ; oc- 

 casionally they utter one loud call. I seldom saw more 

 than two together; but they are tolerably common, frequent- 

 ing the wooded kloofs.
