Birds of Southern Cameroon . 
cleared land, but not at Efulen or at Assobam, both situated 
in country that is almost all forest. 
“Kamangs” are fearless and perch in conspicuous places. 
At Bitye a pair of them, that probably had a nest in some 
high dead limb near by, used to be heard continually and 
seen chasing the Kites over the village farms.

Nos. 4119, 4152,4421. All adult. Bitye, R. Ja. Length 
of wings 320-350 mm. 
Nos. 4211, 4408 & 4422. All ?, adult. Bitye, R. Ja. 
Length of wings 300-315 mm. 
Iris reddish-brown; bill black, with a dirty white spot in 
the middle on the casque ; feet black, but the soles grey. 
The measurements of these specimens shew a bird hardly as 
large as B. alhotihialis; but otherwise they agree perfectly 
with the original figure and description of B. subquadratus. 
This Miam seems to be as plentiful at Bitye as the other 
( B . albotibialis) , or more so. The pair, Nos. 4421 & 4422, 
were brought down at one shot by my boy; there were four 
or five of them early one morning in a small tree in the 
ekotok , not far from my house. The tree was not a fruit- 
tree and the birds were not feeding, but calling and chasing 
each other. 
This species makes quite a different call from B. albo¬ 
tibialis. 
Bycanistes albo-tibialis. [Miam.]

The only specimen I need mention is No. 4557, a young 
male : irides whitish-grey ; bill of a uniform pale horn- 
colour ; feet brown and grey. The bill has no casque, though 
the base of the upper mandible is greatly elevated above the 
forehead; the bill is short (culmen 110 mm.) and smooth. 
A few of the feathers above the eye are grey or have grey 
margins. The plumage is otherwise like that of the adults. 
The young Miam above described was kept alive, at Bitye,
