Type. A small, imperfectly preserved pinna. Dunker's type 

 specimen agrees best with those English specimens which have 

 ultimate segments of median size, in length and breadth. The 

 details of venation are not shown in the figure. The following 

 definition is given by the author of the species 2 : 



" Sphenopteris fronde tripinnata, apicem versus bipinnata, 

 pinnis alternis distantibus vel plus minus approximatis, pinnulis 

 alternis clavatis petiolatis apice laciniatis vel sub-emarginatis, 

 laciniis obovatis, cuneatis, nervis obsoletis, rhacibus tenerrimis 

 canaliculatis." 



The Kufford Collection has furnished us with an abundant 

 supply of material, which enables us to extend the definition of 

 the species, and evidence is afforded by some of the specimens 

 of fertile fronds as to the probable botanical affinity of this 

 "Wealden fern. 



Frond tripinnate-quadripinnate, deltoid or rhomboidal, rachis 

 frequently flexuous, pinnae alternate, deltoid to ovate-lanceolate; 

 pinnules delicate, decurrent on the rachis, ultimate segments linear 

 acuminate or ovate-cuneate. Venation of the type Canopteridis and
