has a gradually widening broad palatal portion. Anteriorly it 

 carries a large canine tooth which does not fill the alveolus ; but 

 behind the canine I can see no trace of any molar teeth nor of 

 alveoli for such teeth in either skull. 



The prefrontal is large and forms a large portion of the upper 

 border of the orbit. The frontal is fairly short and seems to form 

 portion of the supra-orbital border and meet the postorbital

posteriorly. It may be, however, that part of the bone is in 

 reality postfrontal. There are several irregular sinuses and pittings 

 in the bone, but no definite suture is visible. If this be so, then 

 the condition of the frontal would be similar to that in the Gorgon- 

 opsia. 



There is no preparietal. 



The postorbital bar is long and the postorbital extends some 

 distance along the parietal crest, being interlocked with the parietal. 

 This crest is narrow as in the Therocephalia and. the Cynodontia. 

 There is an elongate pineaf foramen 25 mm. behind the post- 

 orbital bar.
