Pouched Lion *, which conclusion was based on the characters and comparisons of those 

 fossil remains detailed in the foregoing pages. 



The concurrence in them of so many cranial characters found only in the Marsu- 

 pialia, will be deemed, I apprehend, demonstrative of the marsupial nature of the 

 TJiylacoleo ; and, amongst existing Marsupialia, the SarcopJiilus or Dasyunis ursinus — 

 at present the largest existing species of its genus — seems to me to have the nearest 

 affinities to the TJiylacoleo, although the interval be still very great between them.
