10 ART. 8. — M. YOKOYAMA : 



The pinnules are oblong, obtuse or rounded at the apex ; 

 often a little falcate, and generally about twice as long as they 

 are broad. They are very close together, even overlapping a 

 little. The basal ears which are slightly unequal are more or 

 less distinct. The terminal pinnule which is preserved only in 

 a single specimen (fig. 2.) is cuneate at base, while anteriorly it 

 narrows abruptly. The apex is unfortunately lacking. 



The venation with the exception of the midrib in most of 

 the pinnules is indistinct. But by a proper illumination, one 

 can observe the finer veins arranged in the typical ^^ Neuropteris " 

 style. 



One of the specimens, also from Yen-tai and described by 

 Zalessky as Odontopteris Reichiana Gutb. (Notiz üb. d. Obercarb. 

 Flora V. Jantai, p. 389, fig. 1.) seems to me to belong to this 

 species. 



A laciniated leaf represented in fig. 3, pi. II is an Aphlebia 

 probably belonging to the above species, having been found 

 amongst the frond-fragments of the latter.

A single, isolated pinnule lacking both apex and base. But 

 from its lanceolate shape, apparently acuminate apex and the 

 characteristic venation, there is hardly any doabt about its belong-
