its talons were not fitted to carry away its prey: a single glimpse of 
the powerful, curved, sharp claws is enough to dispel this illusion.

feathered to the toes, which are bright yellow; claws black, very 
strong, and curved. Length, 2’ 9”; wing, 2’ 1”; tail, 13”. The

This bird seems to be very common at Kuruman, Colesberg, Nel’s 
Poort, Beaufort, and the Karroo generally. 
Mr. Rickard notes it from Port Elizabeth, but Mr. Ayres says 
that it is rare in Natal; the same gentleman has met with it in 
the Transvaal territory. According to Mr. Andersson, it is not 
uncommon in Damara Land, and Great Namaqua Land, and Senor 
Anchieta has obtained numerous examples at Huilla in the Mossa- 
medes district. 
‘I should fancy, from the behaviour of one which we kept for some 
time in confinement, and which went to the Zoological Gardens, 
Regent’s Park, that it would make a good hunting eagle. Mr. Arnot, 
of Colesberg, from whom it was received, tells us that it became 
quite as tame with him as with us. We have been informed by the 
Messrs. Jackson, of Nel’s Poort, that these birds constantly accom- 
pany persons in pursuit of game, and have been seen by them to 
carry off wounded Vaal Knoorhaans (Otis vigorsii) and hares. Their 
depredations on the flocks cause them to be killed on all occasions ; 
but they are still very numerous in the Karroo. We found a nest, 
evidently inhabited by young birds, in the month of January. It 
was a large mass of sticks in the top of a high, scraggy, and to us 
inaccessible tree, on the banks of the Dwass River, near Mr. Jack- 
son’s residence. Mr. H. Jackson subsequently took two eggs from 
this nest in the middle of June. They were of a rounded oval, 
white, more or less spotted and blotched with dry blood-coloured 
spots and patches. Axis, 2’’ 9’; Diam. 2’’ 1”. Mr. Henry 
Buckley writes: “‘ They vary from 2°82 x 2°17 inches to 2°70 x 1:52. 
In colour they are white, blotched with faint ashy grey.” One that
