concolor type in relatively large size and massiveness of the cheek- 

 teeth, in the extreme width of the posterior region of Pg and P 5 , and 

 in the stronger backward curvature of the long coronoid process.

men differs in the more massive lower cheek-teeth, in the greater width 

 of P3 and Pj, in the relatively shorter anteroposterior diameter of 

 P 5 , and to some extent in the greater degree of backward curvature 

 of the coronoid process. 



Several mandible specimens from Rancho La Brea show the char- 

 acters of the type specimen of F. daggetti. Among these is the pos- 

 terior portion of a lower jaw representing the first puma-like form 

 recognized in the Rancho La Brea fauna.*
