and that in all, when one premolar is absent, it is the third and 

 not the second, whether above or below. 



Of course these formulae are still merely provisional, and liable 

 to modification when good examples of the respective milk- 

 dentitions are available for examination.

2 . 2672, Near Yuen-ching-hsien, Sze-chwan. 5200'. 



9. SoREX WARDI FUMEOLUS. 



Thos. Abstr. P. Z. S. 1911, p. 49 (Oct. 31). 



c?. 2606,2616,2627,2657. $. 2638.2656. Wei-choe, on 

 iSi-ho River, W. Sze-chwan. 6000-11,000'. 



Larger and darker-coloured than true wardi, the brain-case 

 broader. Fur about 6 mm. in length (winter). General colour 

 nearly the same brown as in S. hedfordke or a little greyer, 

 decidedly dai-ker than in S. wardi. Dark dorsal line well marked 

 in all the specimens, rather more diffuse than in the other striped 

 species, but this may be due to the greater length of the winter 

 coat. Under surface markedly greyer than upper (" smoke- 

 grey "), while in 8. hedfordi(B there is little difference between 

 the two. 



Skull, like that of S. tvardi, at once distinguishable from that 

 of S. hedfordice by its lower and less vaidted brain-case. From 

 that of the tj'pe of S. wardi it is separated by the rather larger size 

 and by the distinctly greater breadth of the low flat brain-case. 



Dimensions of the type, measured in the flesh : — 



Head and body 60 mm. ; tail 60 ; hind foot 13 ; ear 8. 



Skull : condylo-basal length 18*1 ; condylo-incisive length 18-5 ; 

 breadth across bi-ain-case 8-4 ; upper tooth-series 8"1 ; height of 

 bra in- case from basion 4' 6. 



Hah. as above. 



Type. Adult male. B.M. No. 11.9.8.17. Original number 

 2627. Collected 24 November, 1910. 



This little striped Shrew has a considerable resemblance to 

 S. hedfordiae, but its flattened skull indicates that it is really 

 more allied to S. wardi, of which it may be considered a darker- 

 coloured I'epresentative. 



10. SORICULUS IRENE. 



Thos. Abstr. P. Z. S. 1911, p. 49 (Oct. 31). 



c^. 2674. $. 2673. Yuen-ching-hsien, S.W, Sze-chwan. 

 5200'. 



General characters of S. macrurus, but brain-case much lower. 



Size about as in aS'. macrurus. Fur soft and fine ; hairs of back 

 (winter) about 6*5 mm. in length ; about 5*0 mm. in what I 

 believe to be summer specimens of the same species. General 

 colour above uniform slaty grey (grey no. 4) ; under surface paler,
