orbits dusky ; posterior part of the exterior of the ear, and a patch behind and below it, white ; throat, 
chest, abdomen, inner side of the limhs and apical half of the tail white ; moustaches black. 
Other examples from that island have the upper surface very much darker. 
Specimens from Swan River are still darker, not only on the upper but on the under surface, which latter 
is of a brownish-grey only a trifle lighter than the hue of the upper parts. The colour of one example now 
before me is almost wholly black, somewhat paler beneath, and with a small patch of white on the chest, 
and an interrupted line of white down the throat and abdomen. The colouring, in fact, is much varied 
between grey and black, but never exhibits the rufous hue of the New South Wales animal, Phalangista 
Cooki. 
The figures are somewhat less than the natural size.
