beds of Hainaut (" Flore Bemissartienne "). The section shows an 

 arrangement of vascular tissue identical with that in the recent 

 species : there may be two solenosteles and in addition a solid 

 axial strand. The form of the leaf-trace in the fossil appears to 

 be identical with that in Matonia pectinata (fig. 237, A, p. 310). 



Matonidium Goepperti (Ettingshausen)\ Fig. 269. 



Under this name are included specimens from Inferior

 mately nat. size. ) 



Oolite and Wealden strata in Britain and elsewhere. It is, 

 however, not impossible that if more information were available, 

 we should find adequate reasons for recognising two specific 

 types. Fontaine^, adhering rigidly to the rules of priority, 

 speaks of this species as Matonidium Althausii (Dunker), but 

 Ettingshausen'.s specific term is better known.
