This species jn form and manner of life agrees 

 with the Mus Typhlus or Bhnd Rat, but is, in 

 general, of smaller size, and of a yellowish ash- 

 colour and in some specimens a whitish line or 

 longitudinal streak appears on the .top of the 

 head : the upper fore-teeth are naked, but the 

 lower are covered with a moveable lip : there is no 

 appearance of external ears, and the eyes are ex- 

 tremely small and deeply seated : the head is flat 

 and blunt, the body short and somewhat depress- 

 ed, the limbs very strong, especially the fore-legs, 

 the feet of which are large, naked, and well 

 adapted for burrowing in the ground, having five 

 toes, the three middle of which are furnished with 

 long and strong slightly-curved claws : the hind- 

 feet are also naked, and have five toes with small 

 claws : the tail is very short. 



This animal burrows, like the rest of this divi- 

 sion, raising numerous hillocks in its progress. 

 It is a native of the Altaic mountains, and of the 

 country beyond Lake Baikal. It differs consider- 

 ably in size in different regions ; those of the 

 Altaic mountains sometimes measuring near nine 

 inches in length.
