SCIENTIFIC RESULTS FROM THE MAMMAL SURVEY. 397 



The dorsal colour is relatively dull in this series ; the females 



The skulls are quite

This series differs very noticeably from the typical H. r. sikM- 

 mensis from Pashok in having the backs distinctly rufous and the 

 feet rather lighter; in other respects, e.g., pure white bellies, the 

 presence of 1 2 mammae in the females, and the cranial characters, 

 there is the closest agreement. If siliMmensis could have been spe- 

 cifically distinguished from rattiis, then the Gopaldhara form might 

 well have been treated as a distinct subspecies of the former.

Of 111 specimens of -R. ra^^?(s collected at this locality these 2 

 pure white bellied females alone represent jB. r. sikhimetisi's. They 

 are distinguished from R. r. hhotia by their large size and the pre- 

 sence in them of 12 mammse. The skull of 1064 was specially 

 examined and found to agree perfectly with that of typical siJcki- 

 mensis and to be very different from the other skulls from Hazi- 

 mara ; the circumstance that its teeth were heavily stained with
