These eight specimens are the true B. bicolor and are identical 

 with the southern race from Java, but differ in size and one or two 

 minor points from the large form of the Himalayas, which also 

 occurs in the Malay Peninsula. I have measured the skulls of 

 all the specimens, which entirely bear out my former observations 

 on this race. The average measurements of the eight specimens 

 are : — Greatest length 71*2 mm. ; basal length 56*4 ; zygomatic 

 breadth 43-7 ; length of nasals 21-1 ; length of palate to henselion 

 26-5. 



All these specimens show a tendency to bleaching, although 

 this has taken place to a far less degree than in most of the 

 specimens I have examined ; one or two of the specimens from 

 Biserat, moreover, show a teudency to erythrism, having reddish 

 tips to many of the dorsal hairs, most noticeable on the hind- 

 quarters and tail.
