172 DIN0SA.T7KIA. 



manus and pes ; pubes broad, with long anterior union ; astragalus 

 without ascending process. There seems no reasonable doubt as to 

 the generic unity of Teratosaurus and Zanclodon ; Huxley x identifies 

 the type of the former with the skeleton originally described by 

 Plieninger 2 as Belodon, while Baur 3 refers the latter to Zanclodon, 



[Zanclodon suevicus (Meyer 4 ), 



Syn. Teratosaurus suevicus, Meyer 5 . 



Gresslysaurus ingens, Riitinieyer 6 . 

 Dinosaurus gresslyi, Riitimeyer 7 . 



Of large size, with the serrations on the anterior border of the 

 teeth extending very close to the base. Whether this form is 

 really distinct from Z. lcevis } Plieninger 8 , from the Lettenkohle 

 (Bunter) of Gaildorf, remains to be proved ; the type specimen of 

 the latter is smaller than the type of the present form. 



Hah. Europe. 



38646. The left maxilla, showing five protruded teeth and the germs 



(Fig.) of several in their alveoli ; from the Upper Keuper 



(Upper Trias) of Stuttgart. The type specimen ; figured 



and described by Meyer in the ' Paheontographica,' vol. vii. 



p. 258, pi. xlv. Purchased, 1864. 



38647-8. Two imperfect teeth ; from Stuttgart. Same history. 



38649. An imperfect bone, which is not improbably the right 

 coracoid ; from Stuttgart. Same history. 



38058. A crushed bone, which is not improbably a tibia of this 

 form ; from Stuttgart. The medullary cavity is distinctly 

 shown. The specimen indicates a small individual. 



Same history. 



Zanclodon (?), sp. a. 



This form may be identical with the preceding ; the tooth from 

 the Keuper figured by Huxley in the ' Quart. Journ. Geol. Soc.' 

 vol. xxvi. pi. iii. fig. 11, may belong to it.
