Size markedly smaller than in the typical variety (see skull 

 dimensions, p. ii08), especially in the eastern (Solomon Island) 

 individuals. Colour as a rule similar, but slightly darker than in 

 that form, and the dorsal stripe not quite so constant in its presence. 

 In the islands of Rubiana and Guadalcanar there is also a dark 

 umber-brown race living side by side with the grey one, and not 

 differing from it structurally in the slightest degree ; in this race 

 especially the dark dorsal stripe is quite invisible, being lost in the 

 general dark colour of the back. 



Skull only differing from that of the typical variety by its smaller 

 size. 



Teeth also similar, except that p.*, both above and below, is very 

 considerably smaller and lighter, its diameter, measured obliquely 

 in the direction of the cutting-ridge, averaging about a millimetre 

 less than in the true Ph. orientalis. The small upper p." and the 

 lower intermediate teeth are also more often reduced in number, 

 very few individuals possessing the complete set normally present in 

 Ph. orientalis.
