158 MAESUPIALIA. 



makes an approach to the present form, but differs by the twisting 

 of the axis of these teeth. The enamel of both the incisors and 

 cheek-teeth is finely striated. 



Hah. Queensland and South Australia. 



The following specimens are the types of Sceparnodon. 

 M. 1917. Fragment of an upper incisor, of which one extremity has 

 {Fig.) been cut and polished ; from the Pleistocene of King's 

 Creek, Queensland. Figured by Owen in the ' Phil. Trans.' 

 1884, pi. xii. figs. 1-3 and 9."' 



Presented hy C. II. Hartmann, Esq., 1883. 



M. 1918. Cast of an upper incisor, agreeing in size with the preced- 

 ing. The original was obtained from the Pleistocene near 

 Lake Eyre, South Australia, and is preserved in the 

 Museum at Sydney ; it is figured by Owen, op. cit. pi. xii. 

 figs. 4, 5. 

 Presented hy the Trustees of the Australian Museum, 1881. 



M. 1919. Cast of a larger upper incisor. The history of the 

 original is the same as those of the preceding, and it is 

 figured by Owen, op. cit. pi, xii. figs. 6-8. Same history. 



The following specimens include those figured hy Owen as 

 Phascolonus gigas. 



50075 a. An imperfect fourth upper premolar ; from (? King's 

 Creek) Queensland. The transverse diameter of this 

 tooth is 0,019 ; it has the complex character of pm. 4 of 

 Phascolomys platyrhinus ; and in the striations and reddish 

 stains of the enamel it agrees so exactly with No. M. 1917 

 that it is quite probable that it may have belonged to 

 the same individual. 



Presented hy G. F. Bennett, Esq., 1879. 



43044. The imperfect mandible, showing on the right side the four 

 (Fig.) true molars, and on the left all the cheek-teeth except ^^{Ts ; 

 from the Pleistocene of Eton Yale, Darling Downs, 

 Queensland. Figured by Owen in the ' Phil. Trans.' 1872, 

 pis. xxxvi.-xxxviii., and in the ' Extinct Mammals of Aus- 

 tralia,' pis. Ixii., Ixiii. The length of the space occupied 

 by the cheek-teeth is 0,108. 



Presented hy Sir D. Coopjer, Bart. Ahout 1871. 



35977. Cast of the greater portion of the right ramus of the man- 

 dible, showing part of the incisor and all the cheek-teeth.
