838. Dryma@ca arrinis, Smith. Tawny-flanked Grass- 
Warbler. 
Male, Rustenburg, June 6. Irides light hazel; bill dusky 
brown, the under mandible pale at the base; tarsi and feet 
reddish-pale. 
Female, Rustenburg, August 2nd. Ivides hazel ; bill nearly 
black, the basal part of the under mandible ashy white; tarsi 
and feet pale. 
This is a common species in the Rustenburg mountains, 
and is generally found in small companies. 
[In ‘The Ibis’ for 1874, p. 101, I explained that a note by 
Mr. Ayres, which was applied to this species in ‘The Ibis’ 
for 1871, p. 150, was in reality intended to apply to D. fla- 
vicans. Mr. Sharpe, at p. 258 of his edition of Layard, has 
overlooked this correction.—J. H. G.] 
Drymeca Fuavicans (Vieill.). Black-chested Grass- War- 
bler. 
Sex uncertain (black gorget only partially developed). Shot 
near Potchefstroom, 24th May. Ivides bright hazel; bill 
black, tarsi and feet light brown. 
This is not a common species above the Magaliesbergen. 
[Mr. Sharpe is not quite correct in saying at p. 254 of his 
edition of ‘ Layard,’ that in this species ‘‘the tail-feathers never 
have a subterminal spot.” Inthe majority of specimens these 
spots are absent; but I have four (all from Transvaal) in 
which they are not so: these specimens are a black-breasted 
male, killed 17th January, in which the spot is present (more 
or less distinctly) on all the rectrices, a similar male killed 
20th February, a black-breasted female killed the same day, 
in which these spots are present, but less strongly marked, 
and a female without the black breast, in which the spot 
appears on all the rectrices, except the longest and shortest. 
The following are Transvaal specimens in my possession in 
which the subterminal spot is absent from the rectrices :—a
