 Catalogue of the Australian Museum called the 

 Grey Flying Squirrel. 



This animal varies considerably in its colouring, 

 and is often of a greyish-black colour above, the 

 dark hairs of the upper parts of the body beir.g more 

 or less pencilled with grey ; the flank membranes 

 are always of a paler hue than the back, and the 

 limbs are black externally. Specimens which are 

 totally white, and others which are white and irre- 

 gularly variegated with grey, are not rare. 



This species is at once distinguished from all others 

 of the genus,* by the ears being entirely covered ex- 

 ternally with long and dense fur ; they are broader, 

 and not nearly so long in proportion as in P. flavi- 

 venter, which approaches it most nearly in size.

* P. Peronii has the same character, but I regard that as 

 the young of the present species.
