 short spinous processes on the margins of the segments.

Remark. Harvey reported C. laciniata K'utz. from Esqui- 

 mau, B. C. and Puget Sound. This is very likely C. furcata 

 Farl. which abounds around the Sound and which has its 

 tetrasporic form quite resembled to C. laciniata Kutz. Again, 

 C. furcata Farl. has been doubted by Setchell and Gardner, 

 1. c, whether it is to be included under C. obtusifolia J. Ag. or 

 not. In the Agardhian Herbarium, specimens from Santa Bar- 

 bara, together with Alg. exsic. Bor.-Amer. No. 127, under C. 

 furcata Farl. are not at all separable from those of C. obtusi- 

 folia J. Ag. J. Agardh has already noticed this and he referred 

 C. furcata Farl. to C. obtusifolia in his Spec. Alg. Ill, Part IV, 

 p. 17. In the herbarium of the Trinity College, Dublin, a speci- 

 men is determined by Grunow as C. obtusifolia J. Ag., and he 

 brings an authentic specimen of C. furcata Farl. under it.

I identify two specimens from Kiushu to this imperfectly 

 known species. My specimens are also sterile but agree prctty 

 well with the type specimens. The plant resembles to Mvchodea 

 subulata in its external appearance. It differs from the latter 

 by having small, clavate or fusiform ramulets patently pro- 

 liferating from the branches and by having the structure of 

 Rhabdonia.
