84 List of the Mammals indigenous to Tasmania. 
Beautifully figured in Gould’s ‘‘ Mammals of Australia.” 
The common ‘‘Opossum” found all over the island. Both 
the gray and black varieties are united under this species. 
A cream-coloured var. also occasionally occurs. 
Mr. Gould differs from Mr. Waterhouse as to this species. 
Mr. Waterhouse thinks the Tasmanian P. fuliginosa iden- 
tical with the Australian P. vulpina. Whereas Mr. Gould, 
in his splendid work on the Mammals of Australia, considers 
the fuliginosa to be confined to this Island, and to be quite 
distinct from the vulpina, which is restricted to the continent 
of Australia. From Mr. Gould’s long residence and exten- 
sive travels in these Colonies, during which his attention was 
exclusively directed to Zoology, he may fairly be presumed 
to have arrived at the most correct conclusion. I have, there- 
fore, in this instance adopted his opinion.

“ Ring-tail Opossum” of the Colonists. 
This animal is more restricted in its distribution over the 
Colony than the common opossum, (P. fuliginosa), and is 
unknown in very many localities.
