Skeleton. — Skull very strongly ossified, the maxil- 

 laries, squamosals, nasals, etlamoid, and fronto-parietal 

 rugose, granular, or pitted. Ethmoid entirely ossified, 

 confluent with the likewise ossified nasal capsule, and 

 produced forwards beyond the nasals to between the 

 ascending processes of the praemaxillaries ; only a 

 small triangular portion of it is exposed between the 

 nasals and the fronto-parietal. Nasals large, in con- 

 tact with each other between the nares. Fronto- 

 parietal single, widening behind into a more or less 

 developed angular process on each side ; this process 

 is more or less widely separated from a corresponding- 

 one of the squamosal, with which it is connected by 

 ligament only, the prootic being entirely exposed 

 above. Transverse branch of squamosal expanded, 

 plate-like, suturally united in front with the maxillary. 



The degree of roughness of the f ronto-parietals and 

 the development of the post-orbital processes vary 

 according to individuals, the bone being generally less 

 developed in this respect in specimens from France 

 than in those from Germany, Austria, and Italy. In 

 quite young specimens the fronto-parietal is nearly
