Nine specimens of this tree-shrew have been taken by Doctor 

 Abbott in Borneo, two in the Kapuas River region, three in south- 

 western Borneo, and four in southeastern Borneo. (For exact 

 localities, see table of measurements, p. 123.) The only adult specimen 

 from the Kapuas region differs in its much larger size, cranially and 

 externally, from Doctor Abbott's other specimens as well as from 

 specimens from northern Borneo. In color and form, however, it 

 resembles the others in all essential respects. It is no older than 

 some of the smaller individuals. Without more material it does not 

 seem advisable to recognize it as a distinct form.
