These and all the other specimens obtained by the Survey in 

 Bihar and Orissa are really very much alike and call for no special 

 comment. An old specimen (B. M. 66-12-28-6) collected by 

 Mr. R. C. Beavan at Manbhum. Bengal, in January 1865, has 

 longer and softer fur; its belJy is of a pure but creamy white 

 colour ; its back is of a considerably brighter and warmer tint than 

 are those of the specimens described above. 



IiemarJis : — li. r. arhoreus is a subspecies quite sharply difieren- 

 tiated from its allies, living on the other side of the Ganges, in 

 Sikkim, Northern Bengal and Bhutan Douars, by its colder and 

 more pallid coloration, its pure white belly (the phase or ' muta- 

 tion' showing slaty bases to the ventral hairs being, apparently, 

 quite absent), its shorter and especially thinner pelage, and its 

 relatively long tail. The skull, in the hands of a ]iatient observer, 

 is also quite distinctive.
