but with a large dusky patch at the base : tail shortish, grey 
at base, black beyond, excepting about two inches of the 
apical portion, which is white : chest with a deep rust- 
colourcd mark. 
Inhabits Australia : the exact part not known. 
The above description is taken from a specimen in the 
museum of the Zoological Society, which is the original of 
Mr. Ogilby'a description in the Proceedings above referred 
to. its dimensions are as follows :—

1 have never seen a second specimen of this species, which 
in most respects very closely resembles the PhalangUta 
vulpina , hut differs in having the apical portion of the tail 
white. 
I cannot regard this as a well-established species ; other 
specimens are required for examination, and above all, it 
would be desirable to examine its skull and dentition. With 
regard to the white tip to the tail, I must observe, that I have 
seen specimens of the Petaurus bretriceps (an animal of the 
same family), in which the tip of the tail was also white, 
though it is usually black in that animal 1 . 
In the catalogue of the Sydney Museum, I find “ the 
interior of Australia, from Iron-Bark Range, near the Glenelg 
River," given as the habitat of Phalangisia xanthopus. 
1 In some packages containing about fifty or sixty skins of Petaurus brevi- 
ccps, there were two or three specimens which differed in no way from the 
others, excepting in having the tail tipped with white.
