long to Prof. Owen's new genus Lahyrinthodon. In the seven- 

 teenth section of the present Report, were described the remains 

 of the flying reptiles [Pterodactylus rnacronyx) from Lyme Regis 

 and the oohte of Stonesfield. Some remains of undetermined 

 Saurians from the bone bed at Aust Passage, and other localities, 

 were noticed. The nineteenth section contained an account of 

 the fossil Emydes, Trionyces, and Chelonige, hitherto discovered 

 in British strata. The Chelonia Harvicejisis, and two new spe- 

 cies (C breviceps and C. acutirostris) from the eocene clay at 

 Sheppey, were described ; and the characters of a new genus, 

 (Ci?7iochelys,) the remains of which are found in the chalk near 

 Maidstone, were given in detail. 



The indications of Chelonian reptiles in more ancient strata 

 were then noticed, and the femur of a tortoise, from the new red 

 sandstone near Elgin, was described. The fossil reptiles of the 

 order Ophidia, discovered by Mr. Owen in the London clay at 

 Sheppey, have already been noticed; to these were added de- 

 scriptions of a smaller species of Palesophis, from the eocene sand 

 at Kyson, and of a much larger species not less than twenty feet 

 in length, from the London clay at Bracklesham. The last sec- 

 tion of the Report was chiefly devoted to the details of the deter- 

 mination of remains of the fossil Batrachians, identical with the 

 so-called genera Mastodonsaurus and Salamandroides of the 

 German Keuper, and on which the characters of the genus Lahy- 

 rinthodon are based. Reasons were given, showing the high 

 probability that the foot prints referred to the Chirotherium, were 

 those of the Batrachian genus Lahyrinthodon.
