hiteness on the tail, and the variation
in the colour of the body appear to differ in the specimens from the same
place, I have regarded them as belonging to the same species, believing
it to be a variable species which has an extensive range.

From the Table already given it appears that, of the species found on the
Australian Continent, 71 are confined to it, 12 common to it and Van
Diemen's Land, and one common to it and Norfolk Island; while of the 24
species found on Van Diemen's Land, 11 are found in it alone.

The species common to the Australian Continent and Van Diemen's Land,
are:

2. Nyctophilus geoffroyii.

4. Scotophilus gouldii.

5. Scotophilus australis.

15. Dasyurus viverrinus.

27. Perameles obesula.

32. Phalangista vulpina.

38. Hepoona cookii.

70. Hypsiprymnus minor.

81. Hydromys chrysogaster.

84. Mus lutreola.

94. Platypus anatinus.

The species common to Australia and Norfolk Island, but not found in Van
Diemen's Land is:

44. Petaurus sciureus.

The eleven species peculiar to Van Diemen's Land, are:

11. Thylacinus cynocephalus.

12. Diabolus ursinus.

13. Dasyurus maculatus.

17. Phascogale minima.

18. Phascogale affinis.

58. Halmaturus billardieri.

80. Phascolomys ursina.

93. Echidna setosa.

83. Mus setifer.

The last species is also found in Java, from whence it might have been
introduced. It has been known in Van Diemen's Land some years, and does
not appear to have found its way to Australia.

Of the 72 species found in the Australian continent six have only been
recorded as having been found on the North-west coast:

52. Macropus unguifer.
