32874. The proximal portion of the right ulna ; from the Pleistocene 

 of Queensland. Purchased, 1853.

The folJoiuing smaller specimens are provisionally regarded as

42596. The distal portion of the left humerus; from the same 

 locality. Same history. 



M. 3706. The axis vertebra ; from Queensland. No history. 



Genus SARCOPHILUS, F. Cuvier\ 

 The number and homology of the teeth the same as in Dasyurus, 

 but the outer columns of the upper true molars fused together, not 

 forming distinct Y's, and with only a rudiment of the antero- external 

 cusp of the posterior column ; inner cusp of blade of lower true 

 molars rudimentary, and talon very small. Axis vertebra short ; 

 no entepicondylar foramen to the humerus. 



Sarcophilus laniarius^ Owen 2. 



Syn. Dasywus laniarius, Owen ^. 



This species presents a considerable excess in size over the existing 

 Tasmanian S. ursinus, but may probably be regarded merely as the 

 ancestral form of the latter, which, from inhabitiug a continental 

 area, attained superior dimensions. The interdental pits in the 

 maxilla are slightly deeper in the fossil form, and Owen notes a 

 small variation in the contour of the palatal vacuities and the 

 mandible. The smaller specimens identified by Owen-* with S. 

 ursinus probably belong to the female of the present form.
