The skull is considerably smaller tlian the skull of T. helangeri, to which the 

 species is most nearly allied. The frontals are slightly more arched from side to 

 side than in that species and the teeth are considerably smaller, so much so 

 that this character of itself is sufficient to separate it from Tupaia belcmgeri. In this 

 character, and in its smaller size, it approaches T. ellioti and T. javanica, but 

 by the form of its skull it is easily distinguished from these two species. The 

 canine is not much larger than the 1st premolar, and is smaller than the last 

 incisor. The posterior internal cusp of the 1st molar, which is large in T. belangeri, 

 is very small in this species. The middle two of the four external cusps are all 

 but blended into one, so much so that only the faintest indication of a second 

 cusp is perceptible, which is indicated by a slight depression, and this entirely 

 disappears with age. In T. belangeri this additional external process is moderately 

 developed. 



I procured the species first at an elevation of 3,185 feet above the sea on the 

 Kakhyen hills, twenty miles to the east of the valley of the Irawady, and again, at 

 2,400 feet, eighty miles to the eastward of that range. When I first observed the 

 animal it was on a grassy clearing close to patches of fruit, and was so comporting 

 itself that in the distance I mistook it for a squirrel. The next time I noticed 

 it was in hedge-rows.
