regions of the interiör. The type was obtained in Northwestern Borneo opposite the 

 island of Labuan. The typical form is distinguished from all the allied races by 

 having a distinct russet wash on the upper parts of the body, being especially 

 evident on the lower back and at the root of the tail. The tails are very dark 

 almost blackish above, lighter and more yellovvish white along the middle line when 

 seen from below. The shoulder stripe is well-marked in all Mr. Lumholtz' speeimens 

 and almost pure white. There is, however, some variation in the colour of this 

 stripe in speeimens from various localities of Borneo. The lower surface of the body 

 is somewhat variable, and in one of the speeimens examined it is yellowish white, 

 while in the others it is greyish faintly tinged with j^ellow, which colour is continued 

 down the inner side of the arms and legs. The speeimens from Central Borneo are 

 perfectly identical with those from the Eastern districts both as to size and cranial 

 charaoters.

Sumatra and the Malay Peninsula are inhabited by an allied form Twpciia 

 minor malaccanct Anders. In this race the tail is not markedly darker than the 

 upper parts of the body. The Sinkep Island between Sumatra and the Malay Pen- 

 insula is inhabited by still another form T. minor sincipis Lyon, which is very 

 similar to the Bornean animal from which it merely differs by the russet colour of 

 the ramp being distinctly in contrast to the colour of the upper parts of the body. 

 The size is also larger.
