li. Lj'dekker — A SketcJi of the 



[No. 1, 



genus. The teeth of AnJcistrodon, of which only two are known, have 

 laterallj' compressed crowns, with serrated edges, like those of the dino- 

 saurian Megalosaurus and the mammalian Maclicsrodus, and are implanted 

 in distinct sockets. The genus is allied to the Jurassic and Cretaceous 

 Megcdosaurus, and to various Triassic genera. 



From the Denwa group of the Gondwana system, a large crocodilian 

 scute has been obtained by Mr. Hughes,* which seems to belong to Pro- 

 fessor Huxley's undescribed genus Farasuchus. 



Trom the neighbouring Kota-Maleri group, we have the crocodilian 

 Farasiielins and the lacertian Hyperodapeclon. The genus JBurasuclms 

 has never been described, but only incidentally alluded to by Professor 

 Huxleyt ; it was formed for the Kota-Maleri bones : it seems to have been 

 closely allied to the Triassic Selodon and 8tagonolej)is. On labels attach- 

 ed to the bones of Farasuclms, now in the Indian Museum, there occurs 

 tlie specific name of hislopii, in Professor Huxley's handwriting. Sypero- 

 dapedonX is closely allied to the living genus Hatteria (Splienodoii), represen- 

 ted by two species in the ISTew Zealand Islands, and, according to Professor 

 Huxley, to the Triassic Rliynclwsawnis, though this is doubted by Professor 

 Owen. 



From the undoubtedly Jurassic rocks of Kach (Oachh), there has been 

 obtained (Chari group) a vertebra which I think very probably belongs to 

 Farasuclms, though I cannot be certain ;§ and (Umia group) a fragment 

 of a lower jaw of a Plesiosaurus, w\i\c]i I have named P. indicus --W the 

 specific affinities of the latter cannot be fully determined fi'om the 

 fragment. 



Cretaceous. — From the Cretaceous rocks of India, we have, among the 

 Dinosauria, a species of Megalosaurus, certainly from the Trichinopoli, 

 and probably from the Lameta rocks (middle Cretaceous) ;^ this genus is 

 only known in India by detached teeth ; in Europe, it ranges from the 

 Jurassic to the lower Cretaceous (Wealden). From the Lameta rocks, there 

 have also been obtained the remains of another gigantic genus of dinosaur, 

 allied to the Wealden Felorosaurus and the Jurassic Cctiosaurus, which I 

 have named, from the great size of the bones, Titanosaurus ;** from the evi- 

 dence of the vertebi tE, there appear to have been two species, T. indiciis T.
