not very clearly defined from Sc. c. davisoni from Tuvoy and Southern 

 Tenassei'im. They can be exactly matched by topotypes of 

 Sc. c. milleri from Trang, collected in December.

The above series agree closely with topotypes from Trang from 

 which the present locality, which is the most northerly recorded for 

 the race, is geogi-aphically not far i*emoved. 



As noted elsewhere * this squirrel, which in the Western Malay 

 States is largely a denizen of cultivated land, is in the north-east of 

 the Peninsula strictly a jungle haunting species, having been 

 displaced from the villages and orchards by the local forms of 

 Sc. concolor, a larger and heavier animal. In the jungle on Kao 

 Nawng it was by no means common.

Quite identical with topotypes from Trang. 



Sciurtis tenuis appears to be peculiarily sensitive to the influence 

 of elevation. The mountain form of the race occurring in Borneo is 

 different from that found in the lowlands and the same is the case 

 with Sumatran specimens, while Sc. t. tahan from the mountains of 

 the Malay Peninsula is very distinct from the typical form, found on 

 the lower slopes of the same hills.

22. SCIURUS TENUIS GUNONG. subup. nov. 



A mountain form of l:>ciurus tenuis, differing from Sciurus tenuis 

 surdiisf Miller from Trang in its larger size, darker upper sui-face 

 and huffy washed lower parts. Separable from Sciurus tenuis tahan, 

 Bonhote % by its smaller size, slightly paler upper parts and by the 

 absence of the rich buffy suffusion on the inner side of thighs and 

 the inguinal region.
