258 Mr. T. Ayres on the Ornithology of Transvaal. 
This specimen, and the two Buzzards previously mentioned, 
were all shot on the same farm, about a couple of miles from 
Potchefstroom ; the Circaetus was quietly perched on the top 
of a high willow. 
[ Referring to my description and notes of measurements of 
several individuals of this species in ‘The Ibis’ for 1878, 
pp. 152 to 158 and 163, I may mention that the plumage of 
the present specimen seems to me to be intermediate between 
Nos. 2 and 3 in the list there given—the abdomen, flanks, 
and under tail-coverts having white feathers, crossed near 
the tip with a bar of brightish fawn-colour, and most of the 
feathers also showing another similar bar, but imperfect in 
the centre, about the middle of the feather. The following 
are the principal measurements of this specimen :—wing 20°6 — 
inches, tarsus 3°5, middle toe s.w. 1:8, culmen (exclusive of 
cere) 1°5. 
Since the publication of my note in ‘The Ibis,’ above re- 
ferred to, the Norwich Museum has acquired two additional 
specimens of the allied fuliginous species, C. cinereus, of 
which I subjoin the like measurements, for the sake of 
comparison, and in addition to those I have already given in 
‘The Ibis’ for 1878, p. 163.
