R. 2446 (Leeds Coll. 12). Portions of the skull and skeleton of a large individual. The parts 

 preserved are : — exoccipital, anterior portion of premaxillse, vomers, pterygoids, 

 palatines, transverse bones, and numerous fragments of skull : symphysial and both 

 articular portions of the mandible, also many fragments ; numerous teeth (one figured 

 by Lydekker in Quart. Journ. Greol. Soc. vol. xlvi. (1890) pi. v. fig. 1) ; centra of ten 

 cervical vertebrae (one figured loc. cit. fig. 2), centra of two dorsal vertebra; and three 

 caudals, neural arch of atlas and four others (loc. cit. fig. 3) ; second subvertebral 

 wedge-bone ; cervical ribs (text-fig. 4, also loc. cit. fig. 2) ; imperfect humeri, radius, 

 and ulna (loc. cit. fig. 4), femora, tibiae, and fibulas (text-fig. 6, A), and numerous other 

 paddle-bones. 



In this specimen the skull is too much broken to supply any information of 

 importance, the teeth are most perfectly preserved (see Lydekker's figure referred 

 to above). The symphysial portion of the mandible shows very well the extent to 

 which the splenial takes part in its formation. One of the median teeth remaining 

 in the anterior portion of the preinaxilla? shows that in this region the upper teeth 

 bit against the lower and were greatly worn thereby ; further back traces of wear 

 are rarely seen, the upper and lower teeth interlocking, not biting against one 

 another.
