206. Peatalea tenuirostris (Temm.). Slender-billed 
Spoonbill. 
207. Ibis .ethiopica (Lath.). Sacred Ibis. 
These birds are plentiful, frequenting the swamps in flocks 
of fifty or sixty together; but I am not aware that they breed 
here. 
208. Limnocorax niger (Gmel.). Black Crake. 
This species haunts the reeds and rushes on the banks of 
the Movi river. 
209. Porphyrio smaragnotus, Temm. Green-backed 
Porphyrio. 
These handsome birds are common in some of the swamps 
about Potchefstroom, but generally frequent rather deep parts. 
210. Fulica cristata, Gmel. Rufous-knob bed Coot. 
This species is common in Trans-Vaal. 
[ Conf : Ibis, 1868, p. 470.—J. H. G.] 
211. Anas sparsa, Smith. White-spotted Duck. 
This species is found on the Movi river, but is not plentiful 
212. Anas xanthorhyncha, Forst. Yellow-billed Duck. 
This is one of the commonest Ducks in this district. 
218. Thalassornis leuconota, Smith. Yellow-throated 
Diving Duck. 
This species is very scarce here; the specimen sent was 
shot within a mile of Potchefstroom. 
[The following remarks refer to species which have been 
already recorded by Mr. Ayres as occurring in Trans-Vaal.— 
J. H. G.] 
160. Circaetus pectoralis, Smith. Black-breasted Har¬ 
rier Eagle. 
This Eagle makes its appearance at Potchefstroom every 
winter, though in no great numbers. The specimen sent (an 
adult female) I shot in the town in August from the top of a 
willow tree; its stomach contained lizards and also a large 
toad, swallowed whole.
