LIST or MAMMALS OBTAINED BY THE HON. WALTER 

 ROTHSCHILD, ERNST HARTERT AND CARL HILGERT 

 IN WESTERN ALGERIA DURING 1913. 



By OLDFIELD THOMAS. 



(Published hy permission of the Trustees of the British Museum.) 



DURING April and May of the present year a collecting expedition to Western 

 Algeria was made, and Mr. Rothschild took with him ibr the purpose of 

 trapping and skinning small mammals a special collector, Mr. Alan Ruddle, to 

 whose care and attention the excellent condition of the specimens is due. 



Apart from a few odd specimens obtained near the town of Algiers the 

 collection was made at two localities — Oran, on the coast in the north, and Aia 

 Sefra, in the mountains in the centre of Western Algeria, both being regions 

 unrepresented in our series of N. African mammalia. 



As a consequence the series forms a very valuable addition to the available 

 material, and I have therefore thought an enumeration of all the specimens would 

 be nsefnl. 



The most interesting specimens are the Elephant kShrews from Oran, as that 

 being the typical locality of Duvernoy's E. rozeti, they have enabled me to examine 

 and describe a number of other forms of the genus in the British and Tring 

 Museums. I have also ventured to describe the Hare of Ain Sefra as a new 

 species. 



In all 1^9 specimens were collected during the trip, a very creditable 

 number considering the limited time available for the purpose. 



1. Pipistrellus kuhli Natt. 



<J: 59, 83, 102, 109, 110, 111, 112, 113, 114 ; ?: 118, 119, 120. Ain Sefra,. 

 1100 m. 



2. Erinaceus algirus Duv. 

 (J: 30. Lalla Marnia, W. Algeria. 360 m. 



3. Elephantulus rozeti Duv. 



<?: 19; ¥: 22. Mt. Mourdjadjo, Oran. 400 m. 



Topotypes of the species, which was described by Duvernoy from Oran io' 

 1832. 



The arrival of these two excellent examples of the typical E. rozeti creates 

 an opportunity to examine certain specimens from Morocco which have been for 

 some years in the British and Tring Museums under tiie general name of rozeti. 

 These appear to belong to two new forms, which may be considered as subspecies 

 of E. rozeti, as they are both of the larger size distinguisiiing that sj)ecies from, 

 the smaller E. deserti of Biskra and the Sontlieru Atlas.
