Sciurus lokroides. 



1836. Sciurus lokroides Hodgson. J. A. S. B. p. 232. 

 1878. Sciurus lokroides Anderson. Yunnan Expedition, p. 

 247; Sciurus bimaculatus Anderson. 1. c. p. 235. 



The chief difference between Sciurus bimaculatus und Sciu- 

 rus lokroides is that the former has the extreme tip of the 

 tail pure white, preceded by a broad black baud. I re- 

 gard this as an individual phenomenon ; it moreover is a 

 long known fact that the tail in different species of Squir- 

 rels sometimes is ornated with a white tip. For the rest there 

 are no differences neither in skull nor in dentition. There 

 are two upper premolars.
