944 OLDFIELD THOMAS 
distinct from Rh. sumatrensis, of which it may be looked upon 
as a local race. The markings are quite similar to those of that 
species, but the brown in the centre of the crown is deepened 
into black, while the rufous of the cheeks is much intensified. 
The skulls of both are quite alike. 
The two sexes are quite alike in colour, and as to age the 
only difference appears to be that the backs get darker as age 
advances. The foot-pads, as shown in the single specimen pre- 
served in spirit, are exceedingly rough and granulated, and the 
two posterior pads are run together into one large triangular 
pad, the anterior four being small and rounded us usual. The 
hind-foot of this specimen measures 59 mm. in length, and 
the ear 14.

those of R. badius.

Mammae 2 —2=8 (!). Sole-pads small, rounded, and smooth 
or very faintly granulated. 
(1) One specimen however, out of 19 females examined, has a third inguinal mam- 
ma on one side, but it is but little developed and is no doubt an abnormality.
