CHARACTERS.--Very nearly related to _M. arctoides_, of which it is perhaps
only a southern race. Face red, more brilliant round the orbits; nose and
lips brownish; tail stumpy, thinly haired. Fur rather brilliant brick-red,
especially on the cheeks, flanks, and outside of the limbs. This animal is
known, however, only from young specimens.
DISTRIBUTION.--Malay Peninsula.
