PLEISTOCENE VEKTEBRATES FROM CUMBERLAND CAVE

somewhat reduced. External roots of M^ not so distinctly separated 

 as in M. pennanti. Mi with metaconid much reduced. Maudible 

 with low but anteroposteriorly elongate coronoid process. Masseteric 

 fossa deeply impressed. Coronoid process with two well-defined 

 fossae, one on its external upper half, the other on its inner base. 

 The modifications of the coronoid region are more pronounced than 

 in hving species.
