Only two fragments of this plant liave been ol)t:iine(l, so 

 that exact determination is at present impossible. Though not 

 unlike Dioonites Kotöei in some respects, their generic distinction 

 is obvious, for the Japanese species has simple veins while those 

 from Korea usually fork once.

Two detached pinnae of Fodozamites, distinguished from the 

 following species, by their ovate outline and more numerous 

 veins, are to be identified with F. Reinii Geyler, peculiar to, 

 and abundant in, the Japanese Tetori series, first described in 

 detail by Geyleii and then by Prof Yokoyama. Hitherto it 

 has not been known to occur outside of Japan ; therefore it is 

 to be looked upon as a species indicating a close relationship 

 between the Tetori and the Naktons; floras. 



One of the specimens measures 2.0 cm. in breadth and has 

 forty- two parallel veins with numerous fine interstitial ones. 



1) This genus is here provisionally placed in Cycadophyta according to the customary 

 accoplntion, though its position is not certain.
