margin of the masseteric fossa. On close examination, however, the 

 location of the mental foramina together with the size and position 

 of the canine indicates that its relationships are nearer Eumetopias. 

 As many as ten mental foramina can be made out in this bone.

The external face of the horizontal ramus is flattened superiorly, 

 but, as the inferior border is for the most part broken away, it . is 

 hard to formulate any opinion as to its nature. There is reason to 

 believe, however, that it must have resembled somewhat the type 

 exhibited by Eumetopias. The molariform series are situated very 

 close to the external, not internal, face of the ramus, as is the con- 

 dition in Eumetopias. The internal face of the ramus is so imperfect 

 that no attempt will be made to describe it ; the symphysis is very stout 

 and heavy, obliquely oval in outline and not ankylosed. The sym- 

 physial surface is very much corrugated, yet the rami undoubtedly
