Mr. Wareruouse, who has paid considerable attention to the Marsupialia, in speaking of this animal, says,
“The Hepoona Roo of White’s Journal, the original also of Shaw’s Didelphis Petaurus, is still in existence
in the Museum of the College of Surgeons ; it proves to be the present species, and not the P. Taguanoides,
as has always been supposed. This ought therefore to be regarded as the type of Shaw’s genus Petaurus, if

authors are right in attributing that genus to Shaw; but I do not perceive that he ever regarded the

This fine species is common in all the brushes of New South Wales, particularly those which stretch |

favourites. Like the rest of the genus it is nocturnal in its habits, dwelling in holes and in the spouts of
