Although the upper molars agree best with those of 

 G. hurriance, this specimen is quite different in character and 

 colour of fur and in shape of skull ; neither can it be referred 

 to G. erythruruSj with which I have compared it. It pos- 

 sibly represents a new species ; but, as the tail is imperfect, 

 I do not propose a name for it.

7. Mus hactrianus, Blyth. 



This specimen agrees fairly well with typical examples of 

 M. hactrianits ; but the tail is shorter than the head and body, 

 though this is not of importance in a skin. In comparing 

 this specimen, I have had occasion to examine many speci- 

 mens of M. pachycercus^ Blanford, from Yarkand ; and I 

 may note that that species is quite distinct from M. hactrianus 

 and has been happily named.

8. Arvicola Guentheri^ Danford and Alston. 



Head and body 4-4 inches ; hind foot 0*77 ; ear at front 

 0*4. The external form and colours agree well with the 

 original description of the species from Asia Minor (P. Z. S. 

 1880, p. 62), except that in this specimen the rudimentary 

 thumb of the fore foot has a small nail. The pattern of the 

 molar teeth is very similar to that of ^. Guentherij with the 

 following exceptions : — 



In this specimen '±1 has not the rudimentary fourth angle 

 on the inner side so prominent ,• it is barely indicated. On 

 "li?, however, this posterior inner angle is distinct and must 

 be counted, although in the original description above cited 

 it is omitted. 'J^ has the posterior lobe less prolonged back- 

 wards, and tends less to form an angle on the outside than 

 in the Asia- Minor species. '^^, too, has the anterior lobe 

 more compressed laterally in the present specimen. The 

 following table exhibits the molar pattern according to the 

 usual mode of counting : —
