N. GYLDENSTOLPE, MAMMALS COLLECTED IN SIAM. 15 



14. Ratufa melanopepla Miller. — Miller: Proc. 

 Wash. Acad. 1900 p. 71. — This fine squirrel is strictly ar- 

 boreal and was never seen on the ground. It always keeps 

 in the highest trees and was observed, though always in 

 limited numbers, both in the evergreen and in the more open 

 dry forests, thus it seems to be sparsely distributed över the 

 whole of Siarn. Unlike several other squirrels which when 

 resting or feeding use to carry their tails turned upwards, 

 this species as far as I could observe, always carried it 

 hanging straight down. 



The skull of a female specimen shot a Sakerat on the 

 llth of January 1912 measures as follows (the measures in 

 a parenthesis are those given by Miller for the type):

15. Menetes berdmorei Blyth. — This species was 

 very common in the dry forests both in Northern and Eastern 



Siarn. 



It was always observed near the villages, or in the com- 

 pounds in the towns, but never far into the jungles.
