tail tip which is white. These jast two characters serve to distinguish it 

 at once from the allied Siam form, cinnamomeus, Temminck. 



This is one of a group of squirrels which varies greatly in their colouring, 

 ranging from jet black to pure white. In a paper on the group published 

 in 1908 (A. M. N. H., 11., p. 393) I pointed out the difterence (noted 

 above) between it and cinnamomeus of Siam. The present series quite 

 confirm the result I then arrived at. 



'• On Mt. Popa this species only occurred in the thick jungle on the 

 higher slopes of the Mountain. Seen from a distance in a tree it appears 

 black, the white tail tip showing up conspicuously." — G. C. S, 



Vernacular names — Shin-ngapaw or Shin-ni-'jale (Burma).

Mr. Thomas has kindly examined this series as well as those in the Shan 

 States Collection and the following are his conclusions. 



" It would appear from this series (1) that the Upper Burma representa- 

 tives of S. phayrei are distinguished from the typical form by their greyer 

 and less buffy general colour, and (2) that the prominence of the dark 

 lateral bands on the belly is influenced by season, the bands being strong 

 in examples in fresh pelage and nearly or quite disappearing as the fur 

 becomes worn. 



Although the seasonal series is not complete round the year, there seems 

 a strong probability that the types of >S'. hlanfordi, obtained at Ava in 

 October 1861, without any trace of stripes represent a seasonal phase of 

 this species and I therefore use that name for them." 



Will some member who has access to Ava work out this conundrum 'i

sharply pointed head. There are 5 distinct black stripes on the back. 



Between and outside the outer pair of these on each side is a white stripe.
