466 Ml. O. Thomas on 



as new. Five of these were described in the previous 

 paper. 



Dr. Christy's numbers run up to 1530, but the present 

 account only deals with the later two-thirds of the collection, 

 the earlier series having either been already named by 

 Mr. Dollman or else gone elsewhere for determination. 



The great majority of the mammals here referred to were 

 obtained at two localities, Medje, on a branch of the Ituri, 

 about 27° W E., 2° 20' N., and Poko, some 20 or 30 miles 

 north-west of it, but across the watershed in the Welle basin. 

 The latter is not very far from Emin's locality, Tingasi. 

 The other localities mentioned are mostly in the Aruwimi- 

 Ituri basin. 



By the generosity of the authorities at Tervueren, the 

 British Museum has been allowed to retain examples of 

 nearly all the species obtained, including all those described 

 as new. In particular, we have to thank Dr. Schouteden for 

 his kindness both in placing the collection in our hands for 

 determination and for the liberality with which we have 

 been allowed to select duplicates. The sum of these latter 

 forms a very valuable donation to the British Museum. 



In normal times this list would have been prepared by 

 Mr. Dollman in continuation of the paper he published in 

 the Tervueren Journal in 1914*, but he has gone to serve 

 his country, and it is quite impossible for publication to take 

 place in Belgium. With the consent of the Belgian 

 authorities the paper is therefore prepared by me and 

 published in the * Annals.'
