 Just as Anderson in 1878 regarded nearly all Siamese squirrels 

 as varieties of Sc. ferriu/meus, so to-day we include under S. h. hocourti, 

 no doubt more correctly, a number of animals of varied appearance in- 

 habiting Central Siam, all of which we regard as aberrations of that 

 race. 



Wroughton has defined three subspecies from more northern 

 area.s, but at present the southern animals are all considered to be 

 members of tiie ver}' ciiangeable typical race. 



In colour the present specimen is grizzled black and warm buff 

 above, the latter colour deepening to ocliraceous on the nape and liead. 

 The undersurface is white, tliis colour spreading over the muzzle and 

 thence projecting backwards to surround tiie eyes, and also extending 

 over much of the upper sides of the hands an 1 fjet : excepting the 

 throat and forelimbs, it is tliickly sprinkled with chestnut hairs, wliieh 

 suggest that tlie lower parts are in a state of change between that 

 colour and white, Tlie ears are partly wiiite and partly ochraceous.
