Mr. A. L. Butler on Birds collected in 
specimens are mottled all over with pale red and lilac, 
others are similarly marked, but the markings are mostly 
confined to the larger end. The markings vary considerably 
in different specimens : in some they are larger and more 
distinct, in others they are finer and more clouded.—O.-G.]

No. III.* On Birds collected by Captain E. P. Blencowe 
in the Bahr-el-Ghazal Province. By A. L. Butler, 
P.Z.S., M.B.O.U., Superintendent of Game Preservation, 
Sudan Government. 
In December 1907, Captain E. P. Blencowe, of the Army 
Service Corps, who was proceeding to the Bahr-el-Ghazal 
Province in connexion with the transport arrangements for 
supplying the various military posts, kindly agreed to take 
with him a native boy whom I had trained to skin birds, and 
to collect for me such specimens as he had time to shoot 
along his line of march. 
The following paper contains a list of birds which he 
obtained, with the localities and dates added and a few 
remarks. 
Captain Blencowe left the Nile at Shambe, and travelled 
first to Bumbek (distance about 90 miles), crossing the Lau 
and Naam Bivers; then he marched to the Tonj Biver, crossing 
the Gell Biver on the way (distance about 75 miles over flat 
forest-country with black cotton soil) ; thence to Wau (about 
70 miles—undulating, forest-covered, ironstone country) ; 
from Wau to Ukanda (45 miles—country flat, all forest) ;
