This species is like P.obesula in colour, but the head is shorter, and the belly of that species is white, with white bristles.
Number 37.

Dromicia nana.
The dentition and the peculiar form and character of the tail of this species at once point out that it should constitute a distinct genus from the other Phalangers, from which it differs in many of its habits.
Number 38.

Hepoona cookii.
Specimens from the same locality differ from one another in the extent of the white on the tail, in the darkness of the colour of the fur, and in the limbs and sides of the body being of the colour of the back, or more or less rufous.

There are either five or six species, or only one.
Number 39.
I have retained the name of Petaurista for the flying Phalangers with hairy ears, as Dr.Shaw's Didelphis petaurus is evidently the same as P.
flaviventer, and has naked ears, like the other species, and his name Petaurus should be used rather than Mr.Waterhouse's Belideus for this genus.
Number 40.
Petaurista leucogaster, may only be a variety of P.taguanoides.
Number 42.

Petaurus macrourus.
This species is only known from the figures of Dr.Shaw.They have a specimen of a young Petaurista taguanoides, under this name, in the Paris Museum.
Number 43.
