General colour of the upper parts, including the top of the 
head and outer sides of the limbs and feet, black, profusely 
speckled with fulvous, which is everywhere in excess of the 
darker colour, each hair being grey at its base, shading to 
black at the tip, and having two or three buff annulations. 
The cheeks, face, and chin, including a ring round the eye, 
are of a light rufous brown (tawny ochraceous, Ridg.). The 
extent of this colour on the chin is very variable ; in some 
cases it covers the whole of the underpart of the neck, but in 
the majority of cases it is confined to the tip of the chin, and 
may be traced back along the sides of the neck nearly as far 
5 
as the shoulder, becoming gradually more and more grizzled, 
(oo) 
till it loses itself in the colour of the upper parts. 
The whole of the underparts and inner sides of the limbs are 
of a pale bluish grey (smoke-grey, Ridg.), each hair being 
dark at its base, with a hoary tip; the colour is rather lighter 
on the fore-chest, and in some specimens there is a tendency 
to a darker stripe along the middle line, The light lateral 
line has a tendency to be short and narrow and is very 
yellowish in tint (buff-yellow, Ridg.). The dark stripe is of 
similar dimensions and pure black. The ears do not differ 
from the colour of the back, and there is a distinct patch of 
lighter colour behind them, The tail is of the same colour 
as the back, but the annulations being considerably broader, 
it has sometimes the appearance of being ringed; on the 
underside it has a rather more fulvous tint, but the tip does 
not differ from the rest. 
Skull—From the somewhat imperfect series of skulls at 
my disposal I am unable to notice any characters by which 
the skull of this species may be distinguished. — It is generally 
a trifle smaller and is somewhat narrower. 
Dimensions (from skin):—Head and body 203 millim. 
(approx.) ; tail 193 (approx.) ; hind foot 40. 
Skull: greatest length 48; zygomatic breadth 31; inter- 
orbital breadth 18°6; length of nasals 14; width of nasals, 
ant. 7, post. d. .
