to the inferior carnassial of the African lion. It possesses 

 however a well-developed heel and a minute cusp corresponding 

 to the metaconid. Although the paraconid blade is somewhat 

 worn it seems to show evidence that its anterior margin sloped 

 backward more strongly than the nearly vertical anterior border 

 of this portion of the tooth as it may appear in the African lion.
