figured in vol. ii. pi. xxxii. fig. 7 of Mitchell's ' Three 

 Expeditions into Australia ' (see Owen, op. cit. p. 335). 



Purchased, 1854. 



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

 of Queensland. Purchased, 1853. 



43938. Two specimens of the right calcaneum ; from the caves of 

 the Wellington "V alley. The length of the larger specimen 

 is 0,048. 

 Presented by the Trustees of the Australian Museum, 1870. 



The following smaller specimens are provisionally regarded as 

 belonging to the female. 



43887. A left upper true molar ; from the Wellington Valley. 



Presented by the Trustees of the Australian Museum, 1870. 



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 1 . 



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 V'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. Dasyurus laniarius, Owen 3 . 



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 inhabiting 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 4 with S. 

 ursimis probably belong to the female of the present form. 



Hob. New South Wales and Queensland.
