87. Cladosiphon decipiens (Suring.) Okam. (Syn. Mesogloia decipiens 



Suring. Mus. Bot. de Leyde, Tom. I, p. 75, t. 25). 



By the character of pleurilocular sporangia which I have 

 found in a specimen collected at lyo, I refer this plant to the 

 genus Cladosiphon as J. Agardh has supposed, in his Tiel Alg. 

 Syst. II, p. 76. 



88. Cylindrocarpus rugosa Okam. sp. nov. 



Frond at first forming circular, afterward irregularly expand- 

 ing, leather-like, chestnut-colored, thickish, lubricous crust, attain- 

 ing the size of from a few to 10 cm. or more in expanison, 

 adhering to substraum with its whole under-surface, even on the 

 upper surface when young, soon becoming much wrinkled and 

 folded afterwards.

94. Chtetomorpha spiralis Okam. sp. nov. 



Filaments very rigid, deep green, attached to substratum at 

 the beginning, soon detached from the base on coming in contact 

 with other alg^e which they closely twist round, also entangled 

 and entwined to each other in spiral manner. Lower articulations 

 sub-cylindrical or more or less constricted and ventricose, about 

 300 fi thick in the basal cell, soon attaining 600-750 // in dia-
