SUPPLEMENT. 247 



Larger than T. antiquus (supra, i. p. 175), with broader teeth in 

 which the serrations appear to be less oblique. 



Eeferred to this genus by Huxley in the ' Quart. Journ. Geol. 

 Soc.' vol. xxvi. pp. 43-44, where it is stated that no difference can 

 be detected in the direction of the serrations between the teeth of 

 this from and T. antiquus; but the undermentioned specimens 

 certainly have them less oblique than in the figure of the type of 

 the latter, in which respect they resemble the original figure of the 

 type of the present species. 



Hob. Europe (England). 



R. 1695. The crowns of two small teeth ; from the Upper Trias 

 (? Lower Keuper) of Somersetshire. The larger, although 

 of considerable dimensions, precisely resembles the figure 

 of the type tooth given in the ' Trans. Geol. Soc' ser. 2, 

 vol. v. pi. xxix. fig. 5 1 . Although the lower portion of 

 the anterior border is imperfect, the serrations can still 

 be detected continuing to the base of the crown. 



Presented by Prof. Jdger, 1889. 



Specimens which may be referable either to T. antiquus 

 or T. platyodon. 



R. 1539. Mass of rock showing the dorsal aspect of the imperfect 

 right ilium, and a fragment of another bone ; from the 

 Upper Triassic (Lower Keuper) bone-bed near Bristol. 

 The ilium accords with the specimen figured by Huxley in . 

 the ' Quart. Journ. Geol. Soc' vol. xxvi. pi. iii. fig. 7, from 

 the inner side. By exchange, 1888. 



R. 1544. The imperfect distal half of a femur ; from the Bristol 

 bone-bed. By exchange, 1888. 



R. 1551. Mass of rock showing the ventral surface of a phalangeal 

 of the pes ; from the Bristol bone-bed. 



By exchange, 1888. 



R. 1535. Eragment of rock showing the ventral aspect of the 

 centrum of a caudal vertebra ; from the Bristol bone-bed. 



By exchange, 1888. 



1 In the reproduction of this figure given in Part I. p. 174, the serrations are 

 made too oblique.
