Hypsiprymnus.

H. apicalis. Tasmania.

H. Gilberti West Australia.

H. platyops West Australia.

The true Rat-Kangaroos approach the Bandicoot-tribe, and some of the best naturalists nave classed them as Bandicoots when the skull could not be examined; their limbs are of more equal length; and the tail is like that of the Bandicoots,—short and rather stiff; the head of the Rat-Kangaroo is elongate (that of II. platyops excepted), and the canine teeth are strongly developed.
