attached, reading as follows : — " Halocoelia japonica Harv. 

 Herb. J. Ag. tillhor icke slagtet Halosaccion ; det ar fucoide 

 med Chordariace-stuctur. Det undersokta exetnplaret har sporan- 

 gia unilocularia. F. Kjellman." Okamura has transferred the 

 species to the genus Chylocladia, calling it Ch. japonica Okam. 

 But his amendment, as I was told from him, is not based on 

 any reliable specimen of Halosaccion japonicum Hary. 



Locality. Otaru Bay(!) ; Suttsu (S. Narita, No. Y. 14); 

 Hakodate (Wright, Harvey), (!) ; Rikuzen Prov. (Miss Wain- 

 wright, No. 65.), (Okamura); Iwaki Prov. (Okamura); Yoko- 

 suka (Sayatier, Hariot) ; Ise Prov. (Okamura) ; Shima Prov. 

 (Okamura) ; Mikawa Prov. (Okamura) ; Hold Prov. (Oka- 

 mura) ; Fusan, Corea (Okamura). I have not seen the speci- 

 men from Yokosuka determined by Hariot. But the occurence 

 of this species in the warmer parts of Japan, as reported by 

 Okamura also, is very doubtful to me. The plant has an ap- 

 pearance easily confusible with a r )rm of Rhabdonia robusta J. 

 Ag. which is common in middle parts of Japan. 



Distribution. Florida.

Our specimens have all arching, unilateral ramification, 

 agreeing with var. a described by Harvey. In Phyc. Bor- 

 Amer. No. 886, as in Farlow's Mar. Alg. New Engl., p. 154, 

 the species is mentioned under a synonymous position of Lowen- 

 taria uncinata Menegh. Farlow has done so on the authori- 

 ty of Zanardini. I have not seen Meneghini's specimen and
