I have alreadj' contributed some notes on the "white" squirrel 

 of Siam to this Journal, but this well-preserved series furnishes oppor- 

 tinity for a few additional details. 



Each animal ranges in colour from white to cream, and in 

 several the rump and the greater part of the tail is a warm buff, while 

 some have patches of similar colour on tlie hands and feet. The 

 whiskers are black or white or a mixture of the two, and wherever the 

 skin is exposed or only thiidy clad with hair, as on Hie ears, sides of 

 face, and undersides of limbs, it is black or blacki.sh. 



That the difference between this, the mainland race, S.f.Jin- 

 lai/soni, and S. f. portus, mihi, of Koh Si Chang is only one of size is 

 fully confirmed by this series, which bears out my suggestion that main- 

 land animals would run considerably larger than examples alrea<ly 

 recorded.
