m.' M.' with, the small anterior cusp almost or wholly ahorted. 

 M.* with scarcely a trace of a posterior heel. 



Milk-premolar entirely absent, as well as the tooth (p.*) it would 

 have preceded. 



Habits. Possorial; carnivorous. 



BaTic/e. Tasmania only. (Found fossil in New South Wales.) 



This genus, on account of the number of its teeth, has been nearly 

 invariably either confounded with Dasyurus, or at most only doubt- 

 fully kept distinct ; but there can be no question, judging by the 

 structure instead of the mere number of the teeth, that it is more 

 nearly allied to Thylacinus than it is to Dasyurus.
