Distribution. — The Khasia hills of Assam. 



The type, of which unfortunately the skull appears to have been 

 lost, seems to be immature ; there is however another specimen in 

 the Museum from the same place, Cherrapoonjee, which agrees 

 with the type in every way except that it is slightly larger. The 

 measurements of this specimen are as follows : — Head and body, 

 2"85; tail, 3*25; hind-foot, without claw, '68; fore-arm and hand, 

 •83 ; ear conch, '32 ; nose to ear (skull extracted), '82. 



The ear is very small and has a thin tuft of long hairs springing 

 from the middle of the conch ; there are eight mammae, and in 

 these points and in the reddish hairs about the posterior part of 

 the back and arms, this species seems to be allied to Mus humei ; 

 in size, however, this species differs considerably from Mus 

 humei which is described as 125 mm. or nearly 5 inches long; 

 there is also no sign of the reduction of the 5th toe which is so 

 characteristic of Mus humei.
