Labyrinthodon /rom Warwickshire. 543 



The minor differences in the vertebrae and other parts noticed in the foregoing 

 descriptions need not here be repeated, but sufficient has been recapitulated to show 

 that the extinct Batrachians that characterize the new red sandstones once consti- 

 tuted a family of that order, hardly less remarkable or better defined in its charac- 

 ters than the equally extinct family of Enaliosaurs in the highest order of reptiles. 

 It is not, perhaps, too sanguine an expectation to anticipate that subsequent re- 

 searches may show that the Labyrinthodont family is not less rich in species, 

 manifesting subgeneric modifications of the typical structure. 



The following are those which at present are known : — 



Labyrinthodon Jcegeri. 



pachygnathus. 



leptognathus. 



ventricosus. 



scutulatus.
