Hab. Sumatra. 



This species is closely allied to N. angolensis, agreeing with it in 

 the position of the minute first upper premolar (which is quite ex- 

 ternal to the tooth-row), in the remarkable length of the thumb as 

 compared with other species of this genus (except N. johorensis), 

 and in the peculiar shortness of the fur. It is, however, readily dis- 

 tinguished by the form and size of the ears, and by other characters 

 described above.
