XL. — On Two new Chinese Rodents. 

 By Oldfield Thomas. 



In working out some mammal-skins recently presented to the 

 Jiritish Museum by Mr. F. W. Styan the two following 

 new forms prove to need description. 



The first, a squirrel, is really Mr. Styan's own discovery, 

 as he had long recognized it as distinct from the ordinary- 

 Chinese species S. castaneoventris, Gray, and had sent speci- 

 mens of it to the Museum as long ago as 1886. Without 

 better material I have not until now thought myself justified 

 in describing it as new ; but the specimens lately received 

 prove the constancy of its characters so fully that I have no 

 longer any hesitation in distinguishing it. 



Sciurus Styani, sp. n. 



Allied to, and in the upper view scarcely distinguishable 

 from, S. castaneoventris J Gi'ay, but with the coloured surface 

 of the belly a peculiar reddish cream-colour (" pinkish buff " 

 of Ridgway) instead of the rich rufous (" orange-rufous ") of 

 the older known form. This difference is extremely striking, 

 and, as shown by the dates of the specimens before me, is not 

 due to seasonal variation. Limbs and tail coloured as in the 

 allied form.
