With Grat. filicina, on the other hand, the pre が nt alga shows 
some relations ; for, the が is， in some specimens ， 化 very close resem- 
blance in appearance between the two species. In such specimens, the 
frond is very much elongated tin 过 が main for a greater length simple ； 
then once or twice forks at longer distances, and the segments む om 
the base to apical potion are b がが on both sides with pro じ ferous very 
elongated, simple or once di が antly forked horizontal, distichous branches, 
either naked or clothed with lesser sorts of ramiili. One may easily take 
such forrris for Gmt. fikcvna ， though dichotomous ramification is rarer in 
case in that species. The substance, however, is firmer and more car- 
tilaginous than Grat. fihcma, and moreover, even in those specimens, 
tetraspores are collected in proli も rous younger branches not in older 
が gme 打 ts, while in Grat. fihcma, t が raspoi’es and cy が ocarps are equally 
scattered over the frond. 
Thus I doubt, on the one hand, wh が her the p が sent plant may 
not be a aiciiotomous and 化 ore caddlaginous vaH が y of Gmt. fihcvna> 
if I am not mis1:alceri in referring such forms to this specie ん On the 
other hand, the piresent alga seems to me to be a 打 intermediate form 
between Grat. fihcma and the secticm to whicb. Gmt. dichotoma が c. 
belong. 
The alga is dis か ibuted in a narrow range, having been abundantly 
collec1:ecl in Noto， "Wakasa and Idzumo, which are provinces along the 
coast of the Japan Sea, and lii 优 ei*to has not been brought from the
