a pale grey, tinged with yellowish. The whiskers are black, tipped with 

 white. The ears are short, scarcely appearing above the fur, and they are 

 almost nude, but sparsely clad as in the other species. The feet and claws 

 flesh-coloured. 



The skull has a broader muzzle than the skull of M. (iV.) Jiuttoni, 

 than which it is somewhat larger, exceeding also the size of the skull of 

 M. (JV.) liardioiclcii. It also differs from the skull (AM. (iV) huttoni, in its 

 greater supraorbital breadth and less expanded zygomatic. It has the ex- 

 panded malar process of the maxillary asin Jf. (iV^.) hardwichii and M. {N.) 

 huttoni, but to less extent than in the latter species, than which the lachrymal 

 foramen is much smaller. Its molar teeth are also larger than in M. {N.) 

 Jiuttonif and its anterior palatine foramina are more open. Dr. Scully 

 gives the dimensions as follows : total length 11 "-8, tail 5 "'2, and the weight 

 as 5 "6 oz. The irides he states are dark brown. 



This species was obtained by Dr. Scully at Sanju in Kashgaria and 

 presented by him to the Indian Museum. 



The Indian Museum has received from Muscat, Arabia, a young rat be- 

 longing to this sub-genus, of the following dimensions. Length of body 

 and head 3*'35, tail 2"-30, hind foot 0"'93. Its ears are small and rounded, 

 its tail is rather densely clad with short hairs. It is too young to indicate 

 its species, but it is quite distinct from any of the field rats described in 

 this article.
