CKOCODILIA. 



This specimen is the type, and is figured by Mantell in his 

 ' Wonders of Geology,' 3rd ed. pi. i. (1839), and described 

 by Owen in the ' Rep. Brit. Assoc' 1841, p. 69, and in his 

 ' Wealden and Purbeck Eeptilia' (Mon. Pal. Soc), suppl. 

 viii. p. 2 (1878). Mantell Collection. Purchased, 1838. 



48340. The middle part of the left maxillary region with teeth ; 

 from the Middle Purbeck of Durdlestone Bay, Swanage, 

 Dorsetshire. BeckJes Collection. Purchased, 1876. 



Specimens, of which a considerable number belong to the 'present or 



next species. 



Among the following the teeth and scutes belong to large species 



of the present genus ; and many of the limb-bones and vertebras 



doubtless also belong to the same \ although some of the latter may 



be generically distinct, and are, perhaps, referable to Suchosaurus. 



37972. The nearly entire right ramus of the nmndible, containing 

 several broken teeth of the type of G. crassidens ; from 

 the Wealden of Cuckfield. Purchased, 1863. 



R. 606. The anterior part of the left ramus of the mandible ; from 



the Wealden of Ecclesbourne, near Hastings, Sussex. The 



entrance of the splenial into the symphysis is well shown. 



Dawson Collection. Purchased, 1884. 



R. 726. Fragment of a mandibular ramus, with dental alveoli ; 

 from the Wealden of Sussex. Purchased, 1886. 



R. 974. The anterior portion of the left ramus of the mandible of 



a young individual, showing thirteen dental alveoli, with 



two perfect teeth in situ ; from the Wealden of Cuckfield. 



Presented by Major Sergison, 1887. 



2512. A tooth ; from the Wealden of Cuckfield. Figured in 

 (Fig.) Mantell's ' Fossils of Tilgate Forest,' pi. v. fig. 10. 



Mantell Collection. Purchased, 1838. 



2350, 2352, 2354. Three teeth ; from the Wealden of Cuckfield. 



Mantell Collection. Purchased, 1838. 



1 In addition to the species mentioned here, Koken ('Pal. Abbandl.' vol. iii. 

 pt. 5, pp. 327-32 [1887]) has applied the names G. pugnax and G. minor to 

 vertebrae from the German Wealden, while Owen (' British Fossil Reptiliar,' 

 Crocodilia, pi. xiv.) has figured vertebras from the English Wealden as G. cari- 

 natus ; and Moussaye (Bull. Soc. Geol. France, ser. 3, vol. iii. p. 53 [1885]) 

 has made the species G. undidens up m the evidence of a tooth from the Upper 

 Jurassic of France. The vertebrae upon which G. carinatus is founded are keeled, 

 like thoRO referred by Owen to SuchosailTUS.
