Four new Shrewa. 217 



Skull on the whole similar to that of S. sacratus, but 

 rather broader and the brain-case more angularly expanded. 

 ]5asisphenoid region of the comparatively simple structure 

 found in the large S. nic/rescens, with but little trace of tlie 

 lateral fos<oe with ovt-rlianging b >un<Iarie.s which occur in all 

 the available specimens of S. sacraliis. Sucli well-developed 

 fos.-ii« do not occur iu »S'. nujrescens, miuor^ macrurus^ov irtme, 

 and if really constant in sacratus they form a very distinctive 

 mark of that species. Second upper incisor larger than third. 



Dimensions of the type (measured on the skin):— 



Head and body probably about 60 mm. ; tail 48 ; hind 

 foot 12-5, 



Skull: condylo-basal length 18; basal length 1G"4 ; 

 greatest breadth 9'<3 * ; upper tooth-series 8 ; front of }/ to 

 back of m- -i'S.

Type. Old male. B.M. no. 12. 11. 32. 1. Original num- 

 ber 32. Cullected March 1912, and presented by Walter 

 Goodfellow, Esq. Another s|)i;cimen obtained by Mr. A. 

 Owston's native collector in 190i3. 



This shrew is probably most nearly allied to the Hima- 

 layan S. caudaiusj but has a much shorter tail. Fiom the 

 Ciiinese S. sacratus it is distinguished by iis simpler basi= 

 sphenoid region and rather shorter tail. 



Chodsigoa sodalis^ sp. n, 



Smallest species of the genus. 



Size considerably less than in Ch. larvarum, t!ie smallest 

 previously described species of Chodsigoa. Skull not so 

 strikingly flattened as usual, its gerieral shape more like 

 that of other shrews. Upper profile nearly straight, slightly 

 concave over the orbits, slightly convex on the brain-case, 

 Sagittal and lambdoid crests not developed in the type. 



Teeth lighter throughout than those of Ch. larvarum, not 

 only actually, but proportionally, the anterior incisors espe- 

 cially slender and delicate, not one-fourth the bulk of those 

 of the larger species. Pigmentation at a minimum, the tip of 

 the Hrst incisor and the extreme tip of the unicuspids and 

 large premolar being but quite lightly marked with rufous. 



Dimensions of the type : — 



External measurements unknown. 



Skull: condylo-basal length 17'5 mm. ; basal length 16; 



* The greatest breadth in S. sacrattis is recorded as 9"o, but this 

 appears to have been a misprint, as I now make the measurement 

 92 mm.
