Batrachians and Reptiles of Ohio. 



Class: BATRACHIA Brongn. 



Order: STEGOCEPHAU. 



This order includes extinct Batrachia that occur in the Coal 

 Measures of Ohio, mainly in the Upper Barren Measures which 

 are supposedly equivalent to the lower Permian of Western 

 Europe.* 



They were often of enormous length, with shapes resembling 

 lizards. The head and trunk were heavily armoured by bony 

 scales and plates. Twenty-three genera and forty species have 

 been thus far described from the rocks in Jefferson and Columbi- 

 ana Counties.
