blade. It certainly resembles the figure of Gmelin (17C8, pi. 23) 

 which Grunow (1868, p. 72) says represents the habit of the 

 Kurile plant. Two of our plants have cystocarps which are 

 large, projecting more on one surface than on the other, and are 

 in structure distinctly those of a Callymenia. DeToni (1897, p. 

 305) is inclined to refer Grunow's species to Phyllophora ner- 

 vosa (DC.) Greville, but our plant is certainly not a form of that 

 species.

After a considerable study of the variations of C. Galifornica 

 Farlow as it occurs on the western coast of Noi'th America, it 

 has seemed best to refer it to C. Phyllophora. There are two 

 series of variations of this plant, as we understand it, which 

 shade into one another. The one may be characterized by the 

 general orbicular shape of the main frond and its proliferations, 

 with the margins entire or slightly ciliate. This is the type of 

 G. Galifornica. The other series may be characterized by the 

 elongated shape of the main frond and its divisions, with the 

 margins, as a rule, long ciliate. This seems to be the type of 

 G. Phyllophora, and is also the Prionitisf Glevelandii Farlow 

 (1877. p. 242). Both types are represented in our collections, 

 the type of Agardh from Whidbey Island, which may be distin- 

 guished as f . typica, while the other specimens we have seen all 

 belong to the type of C. Galifornica, which may be distinguished 

 as f . orbicularis. Some of the specimens reach a very consider- 

 able size, one leaflet of f. orbicularis, e. g., measuring 30 em. in 

 diameter. The texture of this species is much more firm than 

 that of any other of our species of the genus, even exceeding 

 that of G. or not a and forming the greatest contrast to that of 0. 

 riniformis.
