PETRONIA PETRONELLA. 481 
species is found at Lake N’gami; and I also met with it at Objim- 
binque, at Omapju, and near Otaiorapa. I first met with its nest at 
Omapju, on January 5th, 1867; it was placed on the top of a thorn- 
bush, about seven feet from the ground; and I subsequently found 
several other nests during the same month. ‘The nest is large, 
and is composed of coarse grass outside, and fine grass within, 
and has an additional lining of feathers and other soft and warm 
materials ; it is furnished with a long entrance, sometimes a foot or 
more in length, which ends in a deep and wide hollow. The eggs 
_are from three to six; but the most frequent number is four; they 
Lh 
are larger than the eggs of P. arcuatus, and are invariably covered 
with a glutinous matter which it is difficult to remove, even with the 
help of water.” 
Top of head and back of neck grey; eyebrows, sides of neck, and 
back, chestnut; the latter dashed with dark brown; streak through 
the eye; chin, and throat, black; cheeks, breast, and belly, rusty 
white; wing and tail-feathers light brownish-red. Length, 7” ; 
wing, 3/5” ; tail, 3”. “Iris dark brown, bill liver-brown; legs 
and toes resembling the bill in colour, but paler” (Andersson).

Southern Yellow-throated Sparrow. 
Mr. T. C. Atmore found this species in some abundance at 
Eland’s Post, where, he tells us, they are fond of poking about 
Euphorbia trees. Mr. Jameson obtained specimens during his 
excursion into the interior, and Mr. T. Ayres has given the following 
note of its habits: “These Sparrows are not uncommon about the 
Umvuli, frequenting the high trees and feeding much as the Tomtits 
do, hangiig about the outer twigs and eating the young buds, &c. ; 
as, however, food of all kinds is scarce for birds, this may not be a 
usual habit. They are now mostly in pairs, and their loud sparrow- 
like note often repeated in the early morning attracts one’s attention 
to them.” Mr. Andersson only met with it near the Okavango 
River, where he obtained a few specimens. More recently Senor 
Anchieta has procured a pair at Caconda, where it was called 
* Sue-sue.” 
General colour brown and sparrow-like, with a white eyebrow 
extending from the front of the eye almost to the back of the
