Sept.. 19U.J YEXDO.— NOTES ON ALG.E NEW TO JAPAX. FT. 281 



On our coast there is another form. Its principal segments 

 are elongated lanceolate, bullated and twisted, attaining 2-3 

 cm in breadth 7-12 cm in length. The marginal proliferations 

 are usually few in number and often conspicuous in size. If 

 there had been no proliferations, this form is ought to be iden- 

 tified with G. undulata J. Ac. But the presence of the prolifera- 

 tions, the general appearance of the plant as well as the linking 

 specimens, induce me to regard this as a pronounced form of 

 the first mentioned type.
