elongated and somewhat loosely disposed cells from which larger 

 roundish cells are branched off, and the latter by further divisions give 

 rise to gradually smaller cortical cells. Epidermal cells of inner side 

 of swollen sickle-shaped portion which has firmly twisted on the frond 

 of other algae elongate like papillae, so as to make its holding fast. 



Cystocarps unknown. Tefrasporangia indefinitely scattered 



among the cells of cortical layer of branch, even up to sickle-shaped 

 portion, roundish and triangularly divided. Colour varying from 

 deep red to yellowish. Substance soft-membranceous in younger 

 frond and in those growing in calm places, but more cartilaginous in 

 older ones and in those growing in rough sea. 



Hab. : On the fronds of serveral species of Sargassum in 4 to 

 6 fathoms. Provs. Higo, Iki, Chikuzen, Mikawa, Boshyu, Idzumo, 

 Noto, Echigo and Sado ; Enoshima (Prov. Sagami), Matsushima 

 (Prov. Rikuzen), Shin-hama (Prov. lyo) ; Hakodate, Akkeshi and 

 Shana (Hokkaido). Tetraspoaangia : Summer. 



The seaweed is largely employed as an ingredient in the manu- 

 facture of " Kanten " or seaweed jelly. This marketable seaweed is 

 mainly gathered in the Hekura Islets where the best quality is pro- 

 duced.
