Skull closely resembling in shape that of S. tenuis, troni 

 whicli it mainly difiers by its much smaller size. Cheek-teeth 

 five, the small p 3 cylindrical. 



This little species is probably most nearly allied to S. tennis, 

 from which it may be distinguished by its smaller size and 

 more uniform colour. In some respects it resembles S. murinus 

 of Celebes, but has not nearly so long a tail as that animal.
