General colour of the upper parts, including the top of the 

 licad and outer sides of the limbs and feet, black, profusely 

 speckled with fulvous, Avhich 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 

 as the shoulder, becoming gradually more and more grizzled, 

 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 tendenc}' to be short and narrow and is veiy 

 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. Tiie 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 1 am unal^lc to notice any characters by which 

 tlie skull of this species may b(; distinguished. It is generally 

 a tritle smaller and is somewhat narrower.
