defined by J. L. Bouhote,^ but with slight grayish wliile tips to the 

 hairs of the tail, from near Ihe base to within about an inch of the 

 tip. Very distinct from >S. p. rafflesi. Pure black above, bright 

 " orange-rufous " (Ridgway) below (contrasting strongly with the 

 color of raffesi, which is nearly the " bay "of Ridgway). White 

 stripe on the side as in rafflesi, though the orange-rufous comes 

 higher up on the outside of the hind legs. Sides of face iron-gray, 

 but lighter than in rafflesi, almost white on the sides of the nose, chin 

 of the same color as the cheeks without the longitudinal black line 

 of rafflesi. A number of black hairs on the sides of the body adjoin- 

 ing the white stripe are tipped with orange-rufous, and those farther 

 back with white ; hairs of tail tipped with grayish- white as above 

 described. 



Dimensions as in S. p. rafflesi. 



We should hesitate to describe another race of these squirrels were 

 it not for Mr. Bonhote's statements regarding their constancy 

 within geographic limits and the fact that no rufous-bellied member 

 of the group has apparently been hitherto found on Sumatra. 



The occurrence of this animal side by side with >S'. p. rafflesi 

 makes us strongly suspect that the two are specifically distinct, but 

 without more material it woidd be impossible to decide upon the 

 proper arrangement of all tlie members of the group, should tliat 

 vieW' be accepted.

One male. Goenong Soegi, Lampong District. October and 

 November. 



This specimen seems to approach to F. i. divcrstts Thomas,® being 

 indeed quite red on the sides and the white of the under part dis- 

 tinctly red-tinted. We have no other specimens for comparison, 

 however.
