This is a slightly larger species than P. volans, and differs from it in its dull 

 reddish-brown upper fur. The under parts are white, and the central line of 

 the tail above and below is dusky brownish-black. The tail is shorter than the body 

 and distichous. The ears are rather short, broad at the base and not tufted. Cheek- 

 bristles are absent.
