anterior intermaxillary from the large maxillary bone behind 

 it (fig. 1). This suture is straight and parallel to the base of 

 the tusk in the maxillary bone, which is about an inch behind 

 it The face, which is about 2^ inches in lateral depth from 

 the flat nose to the roots of the teeth, has the aspect of being 

 compressed from side to side. In the middle length of this 

 compressed area, below the orbits and slightly in front of 

 them, are the anterior nares. Another compression (parallel, 

 vertical, and further backward) defines the inflation of the 

 maxillary caused by the roots of the teeth (fig. 3). 



In front of the tooth the palatal edge of the maxillary bone 

 is compressed to a thin sharp cutting border, which descends 

 below the palate, so that the sides of the lower jaw could work 

 between the teeth. There is no doubt that the intermaxillary 

 formed a continuation of this arch, which had the usual con- 

 cave upward recession, though the cutting-edge of the middle 

 part is fractured and lost. Behind the narine the jagal 

 process of the maxillary bone is partly preserved, and behind 

 and below this process the maxillary bone is greatly corn-

pressed, for the head is narrower in transverse measurement 

 behind the socket for the tooth than in front of it. The 

 maxillary is prolonged backward above the pterygoid bone 

 behind the palato-nares, as is shown in latieral aspect of the 

 skull, and forms a wedge which narrows to its hinder termina- 

 tion (fig. 1).
