PLATE XXVII. 



Neuropteris. Sp. 



Unfortunately no notes are to be found by means of 

 which the history of this very beautiful specimen can be 

 traced. It is called Pecopteris on the original drawing, 

 but the manner in which the lobes are attached to the mid- 

 rib, and the angles at which the nervures spring from it, 

 give the frond an essentially Neuropterid character. The 

 heterophyllous nature of the plant is remarkably well 

 shown. 



The locality and horizon are both unknown.
