Nan).

This race differs from berdmorei in the much more pronounced 
black dorsal stripes and lighter dorsal region which is often of a 
colour between Xanthine orange and amber brown, while the under- 
parts are white, but washed with a more intense yellow than the 
buffy undersurface of berdmorei,

This race differs from the typical animals of Peninsular Siam 
in being duller above with the white of the undersurface extending 
on to the muzzle and up the cheeks towards the eyes. The present 
specimen, which is practically a topotype, is darker above than the 
original animal with much more black in the composition of the pelage.
