Expedition to the Zambesi River. 
196. Circaetus cinereus Vieill. 
This species is very Buzzard-like and sluggish in its flight, 
flying, as a rule, much higher than the undergrowth. 
Adult $ (Mesanangue, Sept. 9, 1898). Total length 
(measured in the flesh) 30 inches, wing 22. Weight 3 lbs. 
Iris yellow ; legs and feet whitish flesh. 
Immature ? (Mesanangue, Aug. 26, 1898). Total length 
(measured in the flesh) 29*5 inches, wing 22*5. Iris yellow ; 
legs and feet flesh colour. 
The crop of this last bird contained two large snakes, one 
measuring 40'5, the other 43 inches, and nearly 1 inch in 
diameter. 
197. Asturinula monogrammica (Temrn.). 
An adult female below Tete, Aug. 6, 1898. 
198. Melierax gabar (Daud.). 
Fairly common. Observed chiefly at dusk, swooping with 
a rapid flight in and out of the patches of fish-cane, now and 
again to enter them and cause consternation among the flocks 
of half sleepy Weavers there for the night. 
Adult £ (near Tete, Aug. 6, 1898). Iris bluish black; 
bill black, base coral-red ; legs and feet coral-red. 
Adult $ (Kafue river, Dec. 28, 1898). Iris red; bill 
black, base orange-red ; legs and feet orange-red. 
Immature £ (Chicowa, Oct. 6,1898). Iris orange-yellow , 
cere and base of bill yellow ; legs and feet orange-yellow. 
199. Astur polyzonoides (Smith). 
Two adult males and two immature birds obtained. Preys 
a great deal upon the flocks of Weavers. One of our 
specimens was shot in the act of devouring a small Weaver 
(Pyromelana sundevalli ). 
The flight is erratic, which makes shooting it no easy 
matter, for the bird has a peculiar way of suddenly dipping 
just when shot at. 
200. Accjpiter minullus (Daud.). 
Fairly plentiful, frequenting the marpela-fields of the year 
before and waste places overgrown with reeds and fish-cane
