104 TWO NEW RACES OF SCIURUS FINLAYSONI 



Specimens examined. Fifteen from the type locality, one 

 from Pak Jong, E. Siam, and two from Lopburi, Central Siam. 



For measurements and further details sec references cited 

 above. 



The relationships of many Indo-Chinese squirrels are very 

 difficult to trace. 



8. f. prachin is only a large mainland form of the little 

 island race 8. f. finlaysoni which perhaps, through S. f. rajasima, is 

 doubly linked up with the small greyish grizzled island animals 

 S. f. folletti and S. f. trotteri which certainly belong to the species. 

 Through the last of these there may be connection with the large 

 black 8. albivexilli, with white-tipped tail, of Koh Kut ; and thence 

 to the wholly black animals, the large S. nox. of the mainland and 

 the little S. germaini of Pulo Condore. Still further the coloured 

 phase of tachardi may show that the ferrugineus group of squirrels 

 are only really races of finlaysoni.
