This species is distinguished from the {.receding by having long- 

 er and narrower pinnules, and more delicate secondary veins direct- 

 ed more acutely forward. 



The pinnules are entire and attached to the rhachis by their 

 whole base. This is seen in every one of the specimens here figured. 

 In a specimen from Shimamura (PI. Ill, fig. 2) which may be con- 

 sidered the best we possess, the pinnules are quite free from one 

 another, the longest measuring 19 mm. in length and 5£ mm. in 

 breadth. Veins are here very distinct. They arc delicate, all dicho- 

 tomous and acutely directed forward. A specimen from Ozö (PI. 

 XIII, fig. 4) is on!) 7 a fragment from the upper part of a pinna; but 

 it is readily recognised by the acute course of the veins. That from Ha- 

 le ogase is much better as far as the number of pinnules preserved is con- 

 cerned ; but all of them are more or less wanting 1 along their margins, 

 so that they look more slender than they really are. Their slightly con- 

 tiguous nature at the base, and their falcate shape are, however, perhaps 

 best shown in this specimen (PI. XIV, fig. 1). The Ushimaru speci- 

 men (PI. XI, fig. 4) is also a fragment like that from Ozö. I possess
