308 MR. OLDFIELD THOMAS OX [NoV. 4, 



4. On u Collection of Mammals from Abyssinia, including 

 some from Lake Tsana, collected by Mr. Edward Degen. 

 By Oldfield Thomas, F.R.S. 



[Received October 27, 1902.] 



By the generosity of a gentleman interested in Abyssinia, 

 Mr. Edward Degen was enabled, during the first half of the 

 present year, to make a collecting expedition to Abyssinia, the 

 resulting specimens being all presented to the National Museum. 

 While in Abyssinia Mr. Degen was able to go to the little-known 

 Lake Tsana, in the centre of the country, where, so far as I can 

 ascertain, no mammals have ever been collected since the time of 

 Riippell. 



As might have been expected, the mammals obtained at this 

 locality prove to be of the greatest interest, quite a number of 

 them being new, notably the fine Otter, the large Mungoose, and 

 the Hare, while others, only hitherto obtained by Riippell, form 

 most valuable accessions to the Museum. The most noteworthy 

 of these latter is the little " Mus imbei^his Rlipp.," for which I 

 have found it necessary to propose a new genus. 



The donor is to be congratulated on the highly satisfactory 

 residts of Mr. Degen's trip, so far as the mammals are concerned, 

 the more so as this group had of necessity to receive only secondary 

 attention as compared with the magnificent collection of Fishes, 

 from which Mr. Boulenger has described so many novelties.
