inferior border corresponding to the "ramal process" of Daw- 

 kins and Sanford is below the anterior lobe of M,. The mas- 

 seteric fossa is very deep, and its extreme anterior border reaches 

 forward to a point opposite the middle of the inferior carnassial. 

 The inferior border of the anterior portion of the masseteric 

 fossa is marked by a sharp upward twist occurring just below 

 the deepest portion of the fossa as in one of the specimens of 

 F. spelaea figured by Dawkins and Sanford." 



The coronoid process is extraordinarily large and high. The 

 superior portion swings backward somewhat as in the tiger, so 

 that the posterior extremity extends behind the condyle. 



The form of the angle is intermediate between that of the 

 lion and the tiger; as it projects inferiorly more than in the lion, 

 and less than in the tiger posteriorly. 



Some of the foramina show features which seem to be charac- 

 teristic. 



The infraorbital foramina are rather narrowly oval as in the 

 tiger, and are relatively smaller than in the lion. 



In the palatine region there is a slight but noticeable pecu- 

 liarity in the situation of the posterior palatine foramina. The 

 posterior borders of these foramina in this specimen reach back 

 to a point behind the superior molars. In the lion and tiger 

 they are situated somewhat farther forward. 



In the lateral region of the skull the foramen rotundnm is 

 separated from the sphenoidal fissure by a much thinner bony 

 septum than in the lion, and the space separating this foramen 

 from the foramen ovale seems comparatively wide. 



In the basieranial region (fig. 1) the stylomastoid foramen 

 is not situated farther out from the median plane of the skull 

 than is the median or innermost portion of the inferior border 

 of the auditory meatus. In the lion and tiger the stylomastoid 

 foramen is situated relatively much farther from the median 

 plane. 



The condylar foramen is in this specimen set relatively far 

 back so that on the left side of the skull it can scarcely be said 

 to be included in the opening of the posterior lacerated foramen.
