SCHIZONEURA. / 



Several casts of Schizoneura, which I regard as probably 

 pith-casts, have been figured by Feistmantel, 1 and one of these is 

 shown in Text-fig. 3b. The ridges and grooves in these specimens 

 are much more coarse than in the impressions of the external 

 surface (Text-fig. 3a). Some imperfect casts of a similar nature 

 are included in the British Museum collection. 



Feistmantel z has figured some stems with short broad internodes 

 with oblong leaf-scars at the node, which he has compared with

S. meriani (Brong.), from the Trias of Germany. The specimens 

 are, however, too fragmentary for specific determination. Another 

 fragment figured by the same author 3 as Schizoneura, sp., is also 

 of a doubtful nature.
