Whereas the tyi^e of tliis race of Flying-squirrel was in rather 

 faded and abraded pel.ige, the fur of this example is quite fresh and 

 unwoiii, and tJierefore presents the fi)lio\viiig slight differences from 

 the Sriracha example. Brown of the upper parts rather deeper, griz- 

 zling more copious, white slioul ler-patches very marked, edges of 

 paraclmte pale gi'ey, under side of bodj- rather moi-e white: the colour 

 of the interfemoi"d nienibrane extends slightly on to the tail which is 

 then grey for a sliort distance instead of drabby ; as in the type, the 

 drab colour extends along the under surface almost tc the tip. 



Unfortunately no dimensions have been recorded and the base of 

 the skull lias been cut away. Greatest nasal length, 24..5; greatest 

 breadtli of combined nasals, 1-3.8; p* — m' (alveolar), 17.2; breadth 

 between tips of post-orbital processes, 32 2. For other measurements 

 see table p. 87.

This form of Giant-squirrel was described fVuin sjjecimens taken 

 in tlie extreme south of Tenasserim (Sungei Balik), and has since been 

 received from M(julmein' ; the pi'eseiit example therefore considerably 

 extends its range. It diflfers from R. melanopepla and the various 

 forms of the latter, in not being black on the back. Colour of upper 

 parts deep chestnut-brown, limbs and tail darker ; top of head, 

 ears, hands and feet, black; an iiregulir .Sudan-brown patch on the 

 occiput. Under surface of body and limbs about r.ntimony yellow,
