A. LEITH ADAMS ON GIGANTIC LAND-TORTOISES ETC. 191 



The Author, in reply to Prof. Eamsay, said that it was impos- 

 sible to tell whether the remains from Gibraltar belonged to a land 

 or freshwater species, as the parts of the skeleton preserved did not 

 furnish the necessary evidence ; but the characters of the radius 

 showed that it was not a marine Turtle. In reply to Prof. Seeley, 

 he said that the head of the femur of the large Maltese Chelonian 

 was quite different from that of Colossoehrfys atlas from the Si- 

 waliks, and added that he quite agreed with him that the thickness 

 of the carapace was by itself no evidence of gigantic size.
