'' Piiinue elongated ; pinnules alternate, acutely directed forward, 

 rhomboidal, attenuated below, acute at apex, acutely lobed ; veins 

 equal, fine, repeatedly dichotomous." 



Prof, YoKOYAMA brought two pinnae, wdiich differ from 

 each other in the size and form of the last segments, under the 

 species in question and quite rightly, as tlie Korean material 

 shows that the pinnae of the posterior portion of a frond possess 

 broad segments while those of the anterior portion present narrow 

 ones. As to the identity of the Korean and Japanese forms, a 

 comparison of a specimen shown in fig. 8, pi. II., with fig. 

 la in pi. XII of Prof. Yokoyama will place it beyond all 

 doubt. 



In one of the Japanese examples, all of the pinnules show 

 dark dots around their margin borne on the tip of each lobe ; 

 the fructified example from Korea, fig. 9, pi. III., being distinctly 

 the apical portion of a frond, shows pinnae which are simple- 

 lobed instead being deeply divided into pinnules ; and the lobes 

 which sometimes bear more than one sorus along the inner 

 margin are only the posterior ones. From this, it is highly pro- 

 bable that the fructified example from Japan figured by Prof. 

 Yokoyama is from the posterior portion of a frond. 



The writer has brought this species under the genus Conlo- 

 pler'is for its fructification obviosuly resembles, at least in its 

 external appearrance, some of the recoi'ded cases of fossil Dlcksonia 

 and of the living representatives of the same genus. Yet it must 

 be admitted that with the material at the writer's disposal it has 

 been impossible to examine in any way either the real nature of 

 the sori, indusium and sporangia, or the anatomical characters 

 of the stem. Prof. Yokoyama placed his species in the genus 

 Adianliles, although he admitted the resemblance of its fructifica-
