XXXIIE.—On the Birds procured by Mr. W. N. 
McMillan's Expedition to the Sobat and Baro Rivers. 
By W. R. Oeitviz-Granv. 
Tuts report is based on a large collection of birds made for 
Mr. W.N. McMillan during his expedition to the Sobat 
and Baro Rivers in the Anglo-Egyptian Sudan. A selection 
of these birds, which were collected by Mr. P. Zaphiro, 
was presented by Mr. McMillan to the British Museum. 
Though the collection contains examples of a large number 
of species, few of them are of any special interest, but never- 
theless they are worthy of record, chiefly on account of the 
locality, whence but few specimens have been procured. 
One small Waxbill (Estrilda macmillani) has been described 
as new from this collection.
