I ha\'e no doubt that what Nathor.st calls Chladophlehis sp. in his 

 Beiträge reters t(j this tern. This author had ah'eady recognised its 

 difterence from the closelv aUied Aspleniain CCJiladophlehis) ndufhiense 

 Bro't. in liavini»' the ijinna3 narrowed at base. The reiison whv he left 

 it unnamed was the indistinct venation which characterises most of 

 the fossils of Kyöseki. At Kaisekiyanra, howevei-, where the state of 

 preservati(jn is nuich more fivonrabie, the veins are well preserved, 

 and are quite simihu" t(} those of Aspleninm. lioesserti PresL from the 

 Rhœtic QÏ Yamanoi. (Yokoyama, on s(jme F<3ssil l^lants from the 

 Coal-bearing Series of Xagato, pi. XXIV, figs. 1, 2, 5). The dif- 

 ference between the latter and A. wlu'thiense^ which species are often very 

 difficult to distinguish, has been given in the work just mentioned. 

 In trutli, ChladoplileJiis Xatliorsti shows sucli a. close affinity to 

 Aspleninm lioesserti tliat it would be often quite impossible to dis- 

 tinguish the Uxo, especially when the specimens are present only in 

 fragments.
