This fern, wliicli is so nunierous in the Middle Jiiras.sic of Kagn, 

 Hidn, aud F^cliizen. is also abundantly re|)resented in several of the 

 lor-'dities in Tosa and Awa. It is easily distin2:nished from the nearly 

 related forms l»y the charaeteristic long linear pinnules acutely 

 directed f )rward. Sterile as well as fertile fronds were obtained, the- 

 fertile ones being quite similar to those figured by me in the above 

 mentioned woi'k. 



Nathorst's opinion that SpliCNopteyis j\f(intell/' Schenk of the 

 AYealden and Thiirscqiteris capsuJij'cni Velen. from the Ceuomanian of 

 l>ohenn*',i belong to Onvchiopsis, is, I believe, quite justified. 



JjOC. — Xumerous at Kaisekivama near Sakawa, and Fujikawa in 

 the Katsuragawa basin, ]ess so at Yuasaand Kag;diara. It also occurs 

 at Kat.'iji. TOgodani. and Ishiseki. and bv Xathorst it has been also 

 desci'il)ed from Yakvo, Ueno, Otani, Ilaginotani and Iliura (Mitani).
