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 

 liigli dead limb near by, used to be heard continually and 

 seen chasing the Kites over the village farms.

Nos. 4211, 4408 & 4422. All ? , adult. Bitye, R. Ja. 

 Length of wings 300-315 mm. 



Iris reddish-ljrown ; bill black, with a dirty white spot in 

 the middle on the casque ; feet blach, but the soles grey. 

 The measurements of these specimens shew a bird hardly as 

 large as B. albotibialis ; but otherwise they agree perfectly 

 with the original figure and description of B. subquadratm. 



This Miam seems to be as plentiful at Bitye as the other 

 (5. 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 tlie 

 ekotdk, 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.

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,
