100 CLADOPHLEBIS. 



The pinnae correspond in character very closely to some of those 

 of Heer's species, Gleichenites Zippei? Corda, but there is not 

 sufficient evidence to warrant a removal from the artificial genus 

 Cladophlebis. 



V. 2198. PI. VII. Fig. 4. 



Long pinnae of fairly uniform breadth. The margins of the 

 pinnules are entire, and show no signs of subdivision. Venation 

 not very clear, but rather of the Cladophlelis than Pecopteris type. 

 Cf. Gleichenia Zippei, Corda, as figured by Heer from the Lower 

 Cretaceous of Greenland, 2 also Pecopteris Zippei as figured by 

 Corda in his account of the Lower Cretaceous Bohemian plants, 3 

 and Gleichenia Nordenskioldi, Hr., Fl. foss. Arct. pt. i. pi. i.

V. 2204 and V. 2218. Fragments probably of the same species.

V. 2373. Smaller pinnules in these fragments, but evidently of 

 the same type as C. Broivniana (Dunk.). Ecclesbourne.
