Feb. 20. — A notice was read of the discovery of a perfect 

 skeleton of the fossil genus hitherto called Plesiosaurus, by 

 the Rev. W. D. Conybeare, F.R.S. M.G.S. 



The Plesiosaurus which is the subject of this notice was 

 found in the blue lias of Lyme Regis in Dorsetshire. In the 

 whole exterior portion of its vertebral column the skeleton is 

 entire, and of the remaining parts of the animal few are 

 wanting. In the Transactions of the Geological Society, 

 vol. v. and vol. i. 2d Series, the author had attempted to 

 assign to the various dispersed and disjointed remains of this 

 animal which were then known, their relative places in the 

 skeleton; and his opinions, he observes, have now in all es- 

 sential points received full confirmation. After pointing out 

 those errors into which he had fallen, Mr. Conybeare do-, 

 scribes the osteology of this remarkable fossil animal; the 

 most characteristic and distinguishing features of which are, 

 the extraordinary length of the neck, which fully equals that 

 of the united body and tail; and the number of its vertebrae, 

 which very far exceed that of any animal previously known.
