146 AUSTRALIAN NATURAL HISTORY. 



Kiug and Bennett, at Gowrie, in the Darling Downs district. 

 The splendid casts now in the Museum were prepared under my 

 direction. These casts and models represent the four legs of the 

 marsupial giant, named in honor of Dr. George Bennett, of this 

 city, who was kind enough to put the material for the restoration 

 of an almost perfect skeleton at my disposal. 



There were at least a dozen or more different kinds of Dip- 

 rotodons, but their description cannot now be entered on. 



Genus Ztgomaturus. 



Two species are at present described, but I possess proof that 

 more existed. 



Genus JSTototherium. 



A numerous tribe, represented by perhaps twenty or more 

 species. 



Genus Thtlacoleo. 



Several kinds of this Phalanger have been proved to exist, full 

 descriptions of which will shortly be given. 



Genus Phascolarctos. 

 Phalangista. 

 Belideus. 



Fossil remains of these three genera have been found. 



Tam. Mackopodid^. 



This extensive family was represented by numerous species, 

 many of which are still living. All the short-footed animals with 

 firmly joined mandibles are now extinct, and for these the genus 

 Salmatuthermm {Krefft) has been established. 



The fossil Bettongs are identical with still living species. 



Fam. Phascolomtid^. 



The wombats were also numerous in olden times, and twenty 

 fossil species at least can be demonstrated. 



Pam. Peramelid^. 



The bandicoots are also plentiful in a fossil state. The Peragalea, 

 or rabbit rat, with its peculiar wombat-like grinders, occurs 

 already, and many of these fossil teeth show a continuous growth, 

 like the teeth of all wombats.
