Distinguished from the existing Tasmanian species by its 

 considerably larger dimensions. Small specimens of the skull 

 and jaws cannot be distinguished from those of large males of 

 the latter ; but it is probable that such specimens indicate 

 female individuals, since the sexual disparity of size was pro- 

 bably as well marked as in the living form

Distinguished from the existing S. ursinus in much the same 

 manner as Thylacinus spelceus differs from 2\ cynocephalus, 

 although the disparity between the size of the extinct and 

 living forms is rather less marked than in the case of the 

 latter. In the fossil species the pits between the upper molar 

 teeth are slightly deeper than in the living one ; and there is
