Tuts conspicuously marked species is very abundant in all the rocky districts of Swan Hhiver, and I have little doubt
that the whole of the line of coast of Western Australia will hereafter be found to be inhabited by it wherever the
character of the country is suitable. Independently of its markings and the character of its fur, 7 is a much more
diminutive animal than the P. penicillata ; the crania of these two animals also exhibit sulicer! eres ie ue
the most sceptical mind of their being specifically distinct ; in disposition and economy, however, but little aiference 1s
found to exist between them.
