8. SOIURUS MAOOLELLANDI KONGBNSIS, Subsp. n. 



Sciurus m. barhei Blyth, Bonhote, P. Z. S. 1900, p. 194. 



This collection contains three more specimens of this Squirrel, 

 which, on a close comparison with specimens from other localities, 

 is seen to form a distinct Siamese race of Sc. macclellandi.^ The 

 form it most nearly approaches is Sc. in. barhei, from which it may 

 be distinguished by the general coloration being much greyer and 

 the outer light stripes of a much paler yellow ; these characteristics 

 will hold good at all seasons of the year, for from the material at 

 hand it appears that this race has a seasonal change, which is not 

 known among the Burmese specimens. 



Description of type. (Winter pelage.) 



Genera] colour greyish, each hair being dark at its base with 

 a very pale tip. The outer light stripes very broad and well-marked 

 and of a very pale cream. The inner light stripes slightly darker in 

 colour, but narrow and short. All the three dark stripes duU, owing 

 to each hair having a rufous tip. Hairs of the ears long and 

 conspicuously white, those near the tip having no black bases. 

 TJnderparts pale ferruginous.

Head and body 122 mm. ; tail 133 ; hind foot 29 ; ear 14.
