in Seuiiar Province^ and then travelled slowly up the White 

 Nile as far as Lake No and back. The collections made 

 by them — which have been presented to the Museum and 

 comprise nearly 1600 skins — are most valuable, as they 

 paid great attention to the smaller and more obscure birds 

 and everything was most carefully labelled. 



It was the intention of Capt. Lynes to work out the 

 collection himself, but since the outbreak of the war 

 he has been continually on active service and has not 

 been able to do more than to name a few of the birds. 

 We owe our best thanks to Capt. Lynes for permitting us 

 to make use of his collection in conjunction with that of 

 Mr. Butler, and we hope that later on he will himself 

 publish an account of his experiences and the very valuable 

 field-notes which he made. 



The third collection, from which the Museum is permitted 

 to retain such specimens as they require, was made by 

 Major Cuthbert Christy, R.A.M.C. (T.F.), during a recent 

 journey made in connection with sleeping-sickness investi- 

 gation along the southern border of the Baiir el Ghazal 

 from Rejaf to Tembura (see 'Geographical Journal/ vol. 50, 

 1917, pp. 199-216, with map). 



Major Christy was fortunate enough to secure the services 

 of one of Mr. Butler's trained collectors, and made a 

 valuable collection from a region hitherto never visited by 

 an ornithologist. 



We have therefore a very fine mass of material to deal 

 with, and we decided to endeavour to make our paper a 

 complete list of the Birds of the Anglo-Egyptian Sudan, 

 which can perhaps be made use of later in order to prepare 

 a Handbook for the use of residents and travellers in that 

 region. 



Historical. 



It does not seem out of place to trace briefly the history 

 of the ornithological exploration of the Sudan, but the list 

 of names is a long one and only those of major importance 

 can be mentioned.
