108 Mr. 'T. Ayres on the Ornithology of Transvaal. 
This species seems to keep very much to the low mimosa 
bush ; it always occurs in pairs. 
346. PerRoNIA PETRONELLA (Licht.). South- African 
Rock-Sparrow. 
Female, Rustenburg, 12th July. Inrides umber ; bill and 
upper mandible dusky brown, under mandible pale ; tarsi and 
feet dusky ash-colour. 
I only shot this one specimen, which was feeding on the 
ground in company with Fringillaria flaviventris. 
347. PouiosPizA GULARIS (Smith). Streaky - headed 
Sparrow. 
This is as common a Sparrow about Rustenburg as Passer 
arcuatus (which I did not meet with in the Magaliesbergen) 
is at Potchefstroom. In habits the present species appears 
to be somewhat similar to P. arcuatus, congregating in winter 
in the same manner. 
[In ‘The Ibis’ for 1864, p. 853, Mr. Ayres has given an 
account of Poliospiza gularis, as found by him breeding in 
Natalin December. Mr. Ayres’s Rustenburg specimens were 
obtained in May, July, and August.—J. H. G.] 
CRITHAGRA CHRYSOPYGA, Swains. Golden-rumped Gros- 
beak. 
This species is pretty common about Rustenburg, where I 
found it congregated and feeding amongst stubbles on the 
farms, and sometimes also on the flowers of the parasite that 
the Sugar-birds are so fond of. 
[ Mr. Ayres’s specimens were shot in July.—J. H. G.] 
348, CoLius ERYTHROMELON, Vieill. Quiriwa Coly. 
Male, Rustenburg, 24th June. Irides pale grey ; bill, tip 
black, basal part and also bare skin round the eye crimson ; 
tarsi and feet rose-red (female similar). 
This is the only species of Coly that I found amongst the 
Magaliesbergen ; it is there very common in families, and 
feeds on various berries; its flight is very much like that of 
some Parrots, rapid and straight, with very quick beats of the 
wings.
