 Streaks from the ears mange buff, by no means conspicuous, 

 beneath rusty ferruginous, a patch on breast and mesial line 

 uniform, the rest with greyish bases to the hairs.

 relatively shorter and blunter and the cranium less elongate. 

 Palatal vacuities in both specimens available less defined than 

 in the skulls of T. castanea in the collection. Teeth not 

 different from those of the typi< al form.

 upper molar series, i8'0 (19-2). 



Specimens examined. The type and an immature female, 

 (canine and pin at alve 'his from the same locality.) 



Remarks. The type specimen, though adult, is younger 

 than the available series of seven skulls and four skins of T. 

 castanea, from Pulau Bintang, having the orbital ring not 

 completely ossified. It is however practically adult and has 

 probably attained its full size. The other specimen is very 

 considerably younger. Both are in somewhat worn pelage, 

 while those from Bintang are in fresh, but I think it practically 

 certain that the differences in colour will persist to a greater 

 or less degree when specimens in similar condition are avail- 

 able for study. The differences are certainly of no less order 

 than have been used to establish the majority of races formula- 

 ted of late years.
