The locality of this squirrel — west of the Chiudwin — is 

 separated by a wide area of comparatively low-lying country 

 from that of its near ally D. p. Iioicelli, and one would have 

 expected to lind more differences than the slight reduction in 

 size, Nvhich is, however, siitlicient for diagnostic purposes. 

 All the squirrels of this group are highland dwellers, and it 

 is thoietore probable that none occur in the Oliindwin- 

 Irrawaddy area between the two forms. 



The occurrence of this squirrel on the Cliindwin was first 

 recorded in 1916 *.
