We are informed bj J. E. Gray, Esq., that there is an 

 unnamed Sorex, from the mountains of India, in the collection 

 of the British Museum, which much resembles this species, 

 differing, however, in having the tail very closely covered with 

 short hairs, as well as with the scattered elongated ones 

 described above as characteristic of the present species. 



The specimen from which the above description is taken, is 

 a female, and was found with its male and young among some 

 rotten wood and dead leaves : when caught it bit savagely.

Above, bright rufous, many of the hairs being tipped with black ; 

 ears grizzled sandy white round the margin of the upper part, the 

 hairs of which are short and compact, behind this margin is a tuft 

 of long loose black hair ; the lower surface of the body is light 

 rufous without any black. Tail at the base, the same colour as the 

 body, becoming lighter towards the tip ; the tip itself for more than 

 an inch is black ; feet black ; parachute corresponds as to general 

 colour with that of the body both on the upper and lower surface, 

 except that on the upper surface it passes to a deep ferruginous 

 brown towards the outer edge ; along its outer edge a stripe of 

 sandy white extends from the fore to the hind leg.

 flight is slow, from a higher to a lower point, and appears to 

 be made without motion of the flying membrane, and is, in 

 fact, a mez-e sustained leap. They live and breed in hollow 

 trees, often at a great height from the ground, and run about
