46841 k. The right astragalus, agreeing in size with the preceding ; 

 from Queensland. 



Presented hy Dr. George Bennett, 1875. 



42708. Cast of the right astragalus. The original is from Australia, 



and is preserved in the Adelaide Museum. 



Presented hy the Trustees of the Adelaide 

 Museum of Natural History, 1871. 



39987. The right astragalus of a small individual ; from Darling 

 Downs. Presented hy Sir D. Cooper, Bart., 1866. 



47842. The right astragalus of a small individual; from Darling 

 Downs. Presented hy Dr. George Bennett, 1875. 



42709. Cast of a navicular. The original is from Australia, and is 



preserved in the Adelaide Museum. 



Presented hy the Trustees of the Adelaide 

 Museum of Natural History, 1871. 



46837. The fifth left metatarsal ; from Queensland. This bone 

 agrees in general characters with the corresponding meta- 

 tarsal of Phascolomys and Phalangista, but in its small 

 distal condyle shows indications that the phalangeals (as 

 in the corresponding digit of the manus) were aborted. 



Presented hy Dr. George Bennett, 1875. 



48416. The slightly imperfect atlas vertebra; from Queensland. 

 In the great relative size of the vertical diameter this 

 bone comes nearer to Phalangista than to Phascolomys 

 or Macrojpus ; it differs from the latter in the greater 

 ( thickness of the transverse processes, and from that of 

 Phascolomys and Nototherium in the near approximation 

 to the middle line of the two portions of the inferior 

 arch ; in Phalangista these two portions unite. 



Presented hy Dr. George Bennett, 1874. 



48416 a. The slightly imperfect atlas vertebra ; from King's Creek, 

 Clifton. Presented hy Dr. George Bennett, 1873. 



M. 3. The complete atlas vertebra of a very large individual ; from 

 Australia. Presented hy Sir G. Verdon, 1877. 



32870. The axis vertebra ; from Australia. Figured by Owen in 



{Fig.) the 'Phil. Trans.' 1870, pi. xhii. fig. 1, and pi. xliv. 



figs. 1-3, as well as in the ' Extinct Mammals of Australia, 



pi. xxviii. fig. 1, and pi. xxix. figs. 1-3. The relative 



proportions of this bone agree very closely with those of
