expedition of Mr. Rothschild on the platean to the north-west of Biskra are of so 

 different a colour as to deserve snbspecitic distinction from the desert race. 

 The new form maj' be called 



Elephantulus deserti clivorum subsp. n. 



Essential characters of true deserti, but colour darker, the vinaceous pinkish 

 buff of that animal being overlaid with a darker shade, chiefly due to the nnmerons 

 black tips to the hairs. As a result the general tone approaches " drab-grey," 

 though still with a strong suffusion of buffy. Sides less clear buffy than in deserti, 

 more drab-coloured. White colour of undersnrface apparently covering less of the 

 flanks than in deserti. 



Dimensions of the type, measured iu the flesh : 



Head and body, 98 mm. ; tail, lill ; hind-foot, 32 ; ear, 25. 



Skull, greatest length, 33; condylo-basal length, 30'5 ; zygomatic breadth, 19-7 ; 

 upper tooth series, 17. 



Hab. Plateau of Eastern Algeria ; type from Guelt-es-Stel, alt. 900 m. 



Type. Adult female, B.M. No. 12.6.12.45. Original number 80. Collected 

 and presented by Dr. K. Jordan. Four specimens from Guelt-es-Stel and one from 

 Maafa (W. H. Lindsay) examined, as compared with nearly a score of the 

 true deserti. 



I have also seen a specimen from Matmata, South Tunis, collected by 

 Miss H. L. M. Pixell, which appeared to belong to this subspecies.

<? : 5, 6 ; ? : 1, 3. Algiers. 



The N. African representative of the common White-toothed Shrew is dis- 

 tinctly darker than its European ally, with a particularly dark-coloured head, 

 and is no doubt worthy of subspecific recognition. 



Tbe animal figured by Levaillant as Sorex agilis — on wliich the I'achi/ura 

 agilis of Loche is founded— is obviously a young example of this common 

 Shrew. Loche saw no specimen of it, and had no real evidence as to its being 

 a Pachyura. 



6. Crocidura whitakeri de Winton. 



Crocidura suaveohns Lataste, Mamm. Barb. p. 209 {nee Pall.). 



c? : 47, 66. Aitn Sefra, 111)0 m. 



These are the first Algerian examples of tbe smaller Shrew referred by 

 Lataste to C. suaveolens that I have seen, and they are therefore most welcome. 

 As already stated, I do not think that Levaillant's Sorex agilis is anything but a 

 young specimen of the common large Crocidura, so that the name is not 

 applicalile to the j)reseut species, in whose synonymy it was placed by Lataste. 



But 1 cannot find, any difference of importance between these specimens and
