The present species has also been collected by Wright in 

 Loochoo and identified by Harvey with L. coenomyce Dcne. 

 under which a specimen is kept in the Trinity College, Dublin. 

 In the Agardhian Herbarium, a specimen of the same source 

 sent from Harvey is in the species cover of L. annulata J. Ac. 

 This is undoubtedly the specimen noted by J. Agardh, but er- 

 roneously assigned to Indian Ocean in his Anal. Alg. Cont. Ill, 

 p. 107. The plant resembles in its external appearance to a 

 small form of L. viscida Ac, from which, however, may be readily 

 separated by the fine annulations in the lower parts of frond. 



Ok amur a enlists L. rugosa Zanard. from Loochoo and 

 Bonin Islands in his Nippon Sorui Mei-i, Ed. II, I.e. I have not 

 seen his specimens. Judging from the remark given by him, his 

 specimens seem to be identified with the present species. 



Locality. Loochoo (Wright, Harvey), (S. Narita, No. 

 38) ; ? Bonin Islands (Okamura). 



Distribution. Tropical parts of the Pacific Ocean.

This plant has been hitherto passing among Japanese al- 

 gologists as a well-grown form of Gymnogongrus japonicus Sur. 

 The latter, however, may be separated from the former by 

 having more regularly fiabellate ramification with shorter seg- 

 ments. When there is no lateral proliferations in the lower 

 segments of frond, which is often the case, the plant is hardly
