fine, and the fur of moderate length ; the forehead, face, chin, throat, belly, and inside 

 of limbs, front of thighs, lower half of fore limbs, and the head and feet, are rich 

 orange-red. The tail is rather bushy, as long as the body without the neck and 

 head ; it is concolorous with the upper surface of the body, but sKghtly more rufous, 

 with a bright chestnut-red tip.

I obtained this species at Thigyain in Upper Burma. 



The skull of S. sladeni has a rather short muzzle with considerable breadth 

 across its base superiorly, and it is a shorter and broader skull than the skulls of 

 squirrels referred to S. hlanfordii. Compared with the skull of the red-headed 

 specimen of S. erythrcBus from Bhutan, there is a decided resemblance between 

 the two, the chief distinction being the less breadth of the base of the muzzle 

 of the latter ; but the teeth of this specimen show it to be young, while the teeth 

 of S. sladeni are much worn by use.

The following squirrels which have been described from Burma and Siam and 

 from some of the small islands which lie off the latter country, appear to me to be 

 only varieties of one and the same species. They are S.finlayson%S,ferrugineus,
