History of tlie Fossil Vertebrata of India.

llanfordi. Titanosaurus was a gigantic aud, probably, land reptile, but whe- 

 ther bipedal or quadrupedal is not known, liemains of another, but much 

 smaller, reptile have been also obtained by Mr. Hughes from the Lameta 

 rocks ; the remains are, however, not suflicient for generic determination, 

 but I think it not impossible that tliey may liave belonged to a dinosaur. 



Of tlie Cretaceous Crocodilia, we only know of one species by some- 

 amphicoelian vertebra and scutes obtained by Mr. W. T. Blanford from 

 the upjier Cretaceous rocks of Sind.* As far as I can judge, from these 

 imperfect remains, they appear to indicate an animal allied to Smhosaurus 

 of the Wealden of England. 



The Chelonia are only known to have existed in India during the Cre- 

 taceous period by the evidence of some broken plates, in the collection of the 

 Indian Museum, obtained from the Lameta group, from the intra-Trappeans 

 of liajamahendri (Rajamundry), and from the upper Cretaceous rocks of 

 Sind. These remains are in far too imperfect condition for even generic 

 determination. 



A large species of IchtJiyoscmrus, which I have called I. iiidictis,f is 

 known solely by a few vertebrae collected by Mr. Foote in the middle 

 Cretaceous rocks of Trichinopoli. IclitJiyosaurus, in England, ranges from 

 the Lias to the Chalk. 



JSocene. — The only specifically known Eocene Indian reptile with which 

 I am acquainted, has been referred by the late Dr. Gray| to the genus 

 Hydraspis belonging to the family Emydidse. The specimen on Avhich the 

 determination rests is a carapace, from the intra-Trappean rocks of Bombay, 

 originally named by Mr. Carter Testudo leitliii. The genus Hydrastis is 

 now found living exclusively in Tropical America. From the Nummulitics 

 of the Punjab, remains of Crocodilia have been obtained by Messrs. Theo- 

 bald and Wynne, of the Geological Survey, but are not generically deter- 

 mined. 



Mio-Pliocene and Pleistocene. — From the Mio-Pliocene Siwaliks and 

 from the Pleistocene Narbadas, a considerable number of reptilian remains 

 have been obtained, but, in many cases, have not yet been described, 

 liemains of Crocodilia have been obtained in considerable numbers from 

 the Sub-Himalayan Siwaliks and from the corresponding rocks of Burma, 

 Perim Island, and Sind ; and many of them have been named by Falconer. 

 Of the genus Crocodilus, a Siwalik species has been identified with the 

 living C. paliistris {bomhifrons, Gray).§ Eemains of a crocodilian have
