Fronds flat, irregularly expanding by the peripheral growth 

 with roundish lobes, firmly adhering to substratum by the under- 

 surface and sinuato-flexuose on the upper side, often becoming 

 confluent. Colour deep blackish-green. 



Utriculi are clavate and elongato subcylindrical below, S-io 

 times as long as diameter and a little thickened at the top. Utriculi 

 branch near their bases close to each other and from this mode 

 of branching of cortical Utriculi it may be inferred that the frond 

 does not much grow in thickness. Fronds when detached from 

 the substratum strongly curves toward the undersurface. 



Hab. : On rocks near low tide. Ryukyu, Ogasawara-Isl., 

 Kyushyu ; Provs. Totomi, Sagami, Boshyu and Rikuzen.
