164. Hirundo albigularis, Strick. Southern White- 
throated Swallow. 
A pair of these Swallows fixed a nest on the side of a beam 
in a deserted building in the town, from which I took three 
eggs; the nest was cup-shaped, or rather like a cup cut per¬ 
pendicularly down the centre and stuck against the beam; it 
was composed of mud and was open at the top, and lined with 
feathers placed loosely in it. 
The eggs (which I took in December) were much incubated, 
they measured 9J lines in length by 7 in breadth, and were 
white spotted more or less throughout, but especially at the 
obtuse end, with reddish brown of different shades. 
12. Hirundo semirufa, Sund. Rufous-breasted Swallow. 
One of the specimens sent had mud in its mouth when shot, 
which looked very much as if it were breeding somewhere in 
the neighbourhood. I killed it near the river, about two miles 
from Potchefstroom. 
166. Cotyle cincta (Rodd.). Brown-collared Martin. 
This species is plentiful here during the summer months. 
83. Cisticqla cursitans (Frankl.). Pantail Cisticola. 
[I have mentioned (Ibis, 1873, p. 257) my view as to the 
identity of this species with C. terrestris and C. ayresii, and 
now append the measurements of four additional specimens, 
sent to me by Mr. Ayres from Trans-Yaal.—J. H. G.]

146. Balearica regulorum (Licht.). Southern Crowned 
Crane. 
The specimen sent is the cock bird of the pair that bred in 
a swamp about twenty-four miles from Potchefstroom, and 
from whose nest my friend Mr. Bodenstein obtained for me 
two eggs in December 1871. 
The hen bird this season found another mate and again
