164 MR. OLD FIELD THOMAS OX 



9. SOREX CYLIXDRICAUDA M.-Edw. 



J . 2507, 2547. $ . 2548, 2555. Omi-san. 9500'. 



These Shrews seemed on arrival to represent a totally new form 

 of the group, for they are conspicuous!)^ marked with a deep black 

 line i-unning down the centre of the back, a coloration hitherto 

 unrecorded in the family. 



But after a personal examination, kindly facilitated by 

 Prof. Trouessart, of the species described under the above 

 name by Milne-Edwards, I have come to the conclusion that 

 Mr. Anderson's specimens ai'e referable to that animal, although 

 its describer made no mention of the dorsal line. Probably the 

 type was skinned out of spirit, and was already discoloured when 

 he described it. 



The skull agrees exactly in size and dental characters with that 

 of the type.

A smaller species with a dorsal stripe. 



Size decidedly smaller than in S. cylindricauda, to which it 

 perhaps bears the relationship that S. minutus does to S. araneus. 

 Fur soft and fine; hairs of back about 4"2-4'4 mm. in length. 

 General colour above brown, something between " bistre " and 

 '• Front's brown"; scarcely or not lighter below. Back with an 

 indistinct doisal stiipe, like that of 8. cylindricauda, but usually 

 less distinct, sometimes only discernible as a faint darker median 

 wash often broken over the shoulders ; in one instance, however 

 (IS'o. 2532), it is as strongly black as in the larger species. Hands 

 and feet pale brown. Tail dark brown above and terminally 

 below, lighter proximally below. 



Skull rather smaller than that of S. araneAbs. Three anterior 

 unicuspids equal; two posterior smaller and subequal, the posterior 

 commonly the larger. 



Dimensions of the type : — 



Head and body 55 nun. ; tail 55 ; hind foot 13. 



Skull: condylo-basal length 17'4, greatest breadth 8"4, upper 

 tooth-series 7*4 ; front of p* to back of m* 3"5. 



Hah. as above. Type from Omi-san, 9500'. 



Type. Adult male. B.M. No. 11.2.1.41. Original nimiber 

 2541. Collected 19 August, 1910. 



The charactei'istic striping of this Shrew is not normally so well 

 marked as in S. cylind,ricauda, but it is quite sufficiently evident 

 in all the specimens to afford a ready means of distinguishing the 

 species from any of its allies. 



I have named this very pretty little species in honour of the 

 Duchess of Bedford, whose interest in zoology is well knoAvn.
