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 available
for study. The differences are certainly of no less order
than have been used to establish the majority of races formulated
of late years.
