Mr. T. Ayres on the Ornithology of Transvaal, 103 
black-breasted male and female, of which the date of the 
capture has not been noted ; an unsexed specimen with hardly 
any trace of the black breast, killed 20th April; a male with 
partial black breast, shot 14th May; and another unsexed 
bird with very slight traces of black on the breast, which was 
obtained cn 28th July. 
Both the absence and presence of the black gorget and also 
of the dark subterminal spot on the rectrices in this species 
would seem to be due to causes of which we are at present 
ignorant.—J. H. G.] 
SPHENGACUS arRicANUs (Gmel.). Pointed-tailed Grass- 
Warbler. 
This species occurs in the Magaliesbergen, but 1s not very 
common. 
339. AnrHoscorus caPensts (Gmel.). Cape Dwarf Tit. 
Female, Potchefstroom, 8th April. Irides umber-brown, 
with an outer ring of pale blue; bill horn-black, but with the 
commissure nearly white; tarsi and feet blue-ash. 
Female, Rustenburg, 29th May. 
This is a common species iu the Rustenburg District; but 
I have never met with its nest. 
[I omitted to number this species when first recorded in 
Mr. Ayres’s Transvaal lists in ‘The Ibis’ for 1878, p. 286; 
I have therefore now supplied the omission.—J. H. G.] 
PaBISOMA SUBCERULEUM (Vieill.). Rufous-vented Grignet. 
This species is not uncommon about Rustenburg. 
Parus areR, Gmel. South-African Grey Tit. 
This Tit is common amongst the wooded hill-sides of the 
Magaliesbergen; it is a restless bird in its habits. 
340. Parus nicer, Vieill. South-African Black Tit. 
Male and female. Irides umber-brown ; bill black ; tarsi 
and feet pale ash-colour. 
As far as I can remember, I have never met with this bird 
in the Potchefstroom district ; but it is common about Rus- 
tenburg, and has similar restless habits to the species last 
mentioned.
