PLATE XLIX. 



Fern Stem. 



This stem has a very Sigillarian appearance, but it 

 is more probably a fern stem somewhat allied to the 

 smoother forms of the Triassic pseudo-genus Chelepteris 

 of Corda. The spiral arrangement of the scars is well 

 known. 



Our Plate is reduced one-fourth from Prior's drawing. 

 The locality is not known.
