54 INTRODUCTION. 



Major Mitchell in the caves of Wellington valley 

 and Buree, (Southern Australia,) and are described 

 in his work* by Mr. Owen : 



1. Dasyurus laniarius, Owen. An extinct species about one- 

 third larger than D. ursinus, which it closely resembles. 

 The canines are proportionately larger. 



2. Phalangista. Species undetermined, but apparently 

 allied to P. vulpina. 



3. Hypsiprymnus. Species also undetermined. 



4. Macropus Atlas, Owen. A species of Kangaroo at least 

 one-third larger than Macropus major. 



5. Macropus Titan, Owen As large as the preceding, but 



differing chiefly in the smaller size of the permanent 

 spurious molar, which, in this respect, more nearly cor- 

 responds with the existing Macropus major. 



6. Macropus Undetermined species. 



7. Halmaturus. Undetermined species. 



8. Phalcolomys Mitch ellii, Owen This species is ap- 

 parently a little larger than the recent species. 



9. Diprotodon, Owen A new genus founded on the an- 

 terior extremity of the right ramus of the lower jaw, 

 with a single large procumbent incisor, which resembles 

 the corresponding tooth in the Wombat, both in its 

 position and enamelled structure and portion ; it differs, 

 however, in the quadrilateral figure of its transverse 

 section, in which it corresponds to the inferior incisors 

 of the hippopotamus. 



It appears from the examination of these fossils 

 from Australia, that they are not referable to any 

 known extra-Australian genera) nor are they re- 

 ferable, from the present evidence, to any existing
