Description of the species. Judging from the references 

 hitherto accessible to nie, no complete frond of the present plant 

 seems to have reached the algologists. They have unanimously 

 remarked that the conceptacles are found in the walls of the 

 vesicles. Tlie present writer was so fortunate as to get many 

 complete specimens at Hakodate and actually to observe the 

 habit in the same localit3\ 



A well grown individual measures 40-50 cm. in total length 

 arising at the base from a knotty stump, which is firmly attached 

 to the substratum. From the surface of the stump there start 

 out several shoots which soon branch into several stems. The 

 bases of the shoots are mostly swollen into rugose knots which 

 give a rough aspect to the primary stumji. In an old plant 

 the shoots often fall off, leaving the basal knots on the surface 

 of the primary stump; the latter tluis becoming much more 

 knotty. These shoots correspond morphologically to the inde- 

 finite branches of Sargassum. 



There are two distinct forms of shoots. One of these satis- 

 fiictorily answers to the descriptions and figures of Cocco2')hora 

 liiliyllamjiliora J. Ac;., and the other to those of Coccophora 

 Langsdorfi't Grey. I shall call the former the Phyllamphora 

 form for convenience sake. This is nothing but a young part 

 of the frond and is always found un-branched and sterile. The 

 latter, called for convenience, Langsdorf's form, as has been 

 well figured by Tfrxer and by Smith, is simple and straight,
