Four new Shrews. 215 



otlier ; sides quite similar to back; under surface almost 

 equally dark. Hands and feet pale brown. Tail rather 

 longer than is usual in S. araneus, dark brown above, rather 

 paler below. 



Skull of about the size of that of S. araneus, but distin- 

 guishable by the much broadened lateral wings of the brain- 

 case, which project out on each side conspicuously more than 

 in araneus, and considerably alter the relative proportions of 

 the breadth to the height and length. 



Teeth. — First incisor shorter than in araneus, its horizontal 

 length going nearly twice in the distance from its hinder 

 edge to the front of j9*, that of araneus only going about once 

 and a half; the posterior cusp more pointed, narrower 

 antero-posteriorly, less of a broadened blade, its antero- 

 posterior and transverse diameters approximately equal. As 

 a consequence of the smaller size of i^, the distance from 

 the front of i^ to the front of p^ is markedly less than in 

 S. araneus, while the size of the molariform teeth is exactly 

 the same. 



\_S. araneus tetragonurus, the large Central and S.E. Euro- 

 pean form, has been used in this comparison ; many of the 

 other races are smaller, while that described below is larger, 

 but the relative proportions are much the same in all.] 



Dimensions of the type (measured in the flesh) : — 



Head and body 75 mm. ; tail 52; hind foot 13 ; ear 6. 



Skull : condylo-basal length 19"5 ; greatest breadth 10*2 ; 

 height of brain-case from basiou 5*4; upper tooth-series S'O; 

 front of p* to back of m- 4*2. 



In no. 6. 3. 6. 211, an old male, the brain-case breadth is 

 10*5 mm., with a condylo-basal length of 19*5. 



Hah. Trebizond region, north-eastern Asia Minor; type 

 from Sumela, 30 miles S. of Trebizond. Alt. 1000-1300 m. 

 Fifteen specimens. 



Type. Adult male. B.M. no. 6. 3. 6. 18. Original 

 number 2024. Collected 12th October, 1905, by A. Robert.

The absence of the tricolor pattern, the expanded brain- 

 case, and the peculiar first incisor will readily distinguish this 

 well-marked species. 



Sorex batis is the " larger longer-tailed form from Asia 

 Minor" mentioned under S. araneus santonus by Miller 

 (Cat. Mamm. VV. Eur. p. 40, 1912). It had not been defi- 

 nitely determined at the time Mr. Miller was doing his work 

 on the group.
