sities being visible between the orbits and on the muzzle ; 

 it is possible that this smoothness may be due to the 

 development the specimen has undergone. 



There is a slight but definite ridge running down the 

 median line from between the orbits to the anterior end. 



The cranium is strongly compressed from side to side 

 at the anterior end, but widens considerably posteriorly 

 to the parietal crest. 



The pineal foramen is very conspicuous just behind 

 the post-orbital bar. 



There is a well-marked septum separating the tem- 

 poral vacuities from the orbits. 



The articular region and symphysis of the lower jaw 

 are well preserved ; no characters of interest are presented 

 by articular and angular, but the post-articular process is 

 short and stout. 



The symphysis is expanded and spatulate, and bears 

 about four teeth on each side. 



The very large teeth of the anterior end of the mouth 

 are all damaged. An upper tooth completely shewn by 

 the breakage of the premaxillae is over 7 cms. long, and 

 lacks a great deal of the crown ; the crown where broken 

 off is nearly 2 cms. in diameter. The crown is circular in 

 section, and is covered with well-marked ridges. There 

 are no visible carinae.
