thereby agrees with Phascolomys, although presenting 

 certain minor points of distinction.

48418. The distal portion of the right femur; from Queensland. 



(Fig.) This specimen agrees in structure with the femur of Phasco- 

 lomys and in relative size with the humerus, No. 46914 ; 

 it is figured by Owen in the ' Quart. Journ. Geol. Soc.' 

 vol. xxxviii. pi. xvi. 



Presented by Dr. George Bennett, 1877. 



39983. The left tibia, imperfect proximally ; from Darling Downs. 

 This specimen differs from the corresponding bone of 

 Diprotodon by the more prominent inner malleolus, by the 

 less flattened distal surface, and the greater development 

 of the muscular ridges on the shaft; in all of which 

 respects it approximates to Phascolomys. 



Presented by Sir D. Cooper, Bart., 1866. 



38787. The right calcaneum; from Darling Downs. This bone, 

 which agrees in relative size with the preceding speci- 

 mens, comes very close to the calcaneum of Phascolomys, 

 but makes some approximation to that of Diprotodon. 



Presented by F. N. Isaac, Esq., 1861. 



M. 3640. The atlas vertebra ; from Australia. This bone agrees 

 closely with the atlas of Phascolomys, but is relatively 

 less expanded laterally than in Diprotodon. Figured by 

 Owen in the ' Extinct Mammals of Australia,' pi. cxxvi. 

 The anterior artery passed through a foramen. 



Presented by Dr. George Bennett. 



39986. The right half of the atlas vertebra ; from Darling Downs. 



(Fig.) Figured by Owen in the ' Phil. Trans.' 1870, pi. xliii.

 Australia. This bone agrees very closely with the sacral
