APATEONID-S. 



209 



Genus MELANERPETUM, Fritsch \ 

 The characters in which this genus differs from the typical but 

 imperfectly known Apateon, Meyer 2 , of the German Carboniferous, 

 are not indicated by its founder. The median thoracic plate has a 

 long stem. 



Melanerpetum pulcherrimum, Fritsch 3 . 



Of larger size than the typical M. jousillum, with a shorter and 

 wider skull. It is suggested 4 that the one may be the adult of the 

 other. 



Hab. Europe (Bohemia). 



R. 350. Electrotype from a fragment of shale, showing the entire 

 skeleton. The original is the type, and was obtained from 

 the Eothliegendes (Lower Permian) of Ruppersdorf, near 

 Braunau ; and is figured by Fritsch in his ' Fauna der 

 Gaskohle,' vol. i. pi. xiv. fig. 1. Purchased, 1882.
