Platemys Bullockii. 1 Wall-case A-B. One of the most 

 conspicuous of the fossil Turtles in the angle uniting the 

 Cases A and B, is labelled as above ; the specific name indi- 

 cating its former possessor, the late Mr. Bullock, in whose 

 museum in Piccadilly it was exhibited many years since. 



This Turtle was discovered in the Eocene clay of the Islo 

 of Sheppey ; the plastron or floor is 16 inches in length and 

 14 inches in breadth, and is almost flat ; the carapace is 

 remarkably low. It belongs to the family of Marsh-Tortoises 

 (Paludinosa) which much resembles the true Land-Tortoises 

 (Testudinidce.) 



CHELONIA Harvicensis. Wall-case A-B. Two fine speci- 

 mens, one exhibiting the inner surface or concavity, and 

 the other the convexity of the carapace of a large marine 

 Turtle, are placed in the centre of this compartment ; they 

 are from the Eocene argillaceous beds on the Essex coast. 

 As remains of this Turtle were often found on the shore, 

 near Harwich, my friend the late Mr. Samuel Woodward, 2 

 figured and described the species as C. Harvicensis in a valu- 

 able work, which was the first attempt to tabulate the 

 British fossils ; a labour since so ably carried out by 



1 Prof. Owen, in Palzeontographical Society's Trans., 1849. PI. XXI. 



2 The father of Mr. S. P. Woodward of the British Museum, one of 

 the Curators of the Palaeontological department.
