78 GOIDE TO THE FOSSIL MAMMALS AND BIRDS. 



"Wall-case such as Dinotherium. The toes, as proved by complete 

 Table-cases skeletons discovered some years ago on the dry salt plain 

 14, 14a, 15. bordering Lake Eyre in South Australia, were five in number 



but remarkably short and slender. ■ 

 Table-cases The remains of kangaroos from the river deposits of 

 14 » 15 - Queensland and New South Wales, and from the Wellington 

 Caves, New South Wales, indicate animals of various sizes 

 from that of the smallest living species to that of a donkey. 

 The unique original collection described by Owen is ex- 

 hibited in Table-cases 14, 15. The largest extinct species 

 referred to Procoptodon and Palorchestes, though essentially 

 kangaroos, had the fore and hind limbs less disproportionate

 probably be unable to leap. 



Table-case The largest of the extinct wombats, found with Dipro- 



14a - todon and the large kangaroos, is Phascolonus, of which the 



lower jaw and upper front teeth are shown in Table-case 14a. 



It was about as large as an ox. Here are also numerous 



remains of wombats of more ordinary size. 



Table-case The phalangers, seem to be represented among fossils by 

 the so-called "pouched lion" of Owen, Thylacoleo carnifex, 

 which is also found with Diprotodon and the large kangaroos 

 in the Australian river deposits and caverns. Numerous 

 unique fragments are exhibited, with a restored model of the
