in the Lydenburg 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 f The Ibis* for 1864, 
pi. ix.—J. H. G.] 
20. Petrocincla rupestris (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. Cossypha bicolor (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 ly 1 ^, bill 1, wing 3|, 
tail 3f, iris hazel, bill black, tarsi and feet ashy. 
Female. Total length 7f inches, tarsus 1, bill J, wing 3f, 
tail 3; 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.
