'that our plant is identical with Kuetzing's from his illustrations (Tab. 

 Phyc. XVI, t. 3)， which seems to me to be nothing but Clioiidria as it 

 will be seen from the description above. Afterward I came to notice 

 that Harvey's Rhodomela crssicaulis is also identical with Kuetzing's 

 plant from the illustrations oiven by vSvedellus in his ^'Algen vegetation 

 eines ceylonischen Korallenrilfes (Botoniska Stud., 1906) r i',s. 3 and 

 9. J, Agar し Ih many years iwo excluded RJiodonicla a' as sic ait lis Harv. 

 in his Sp. Alg. Vol. II, pars III (1863)， p. 890, doubtinc>- Harvey's 

 identification, but in Anal. Al^. (1892) p. 161 he put it under 

 CJiondria. 



As far as my knowledge goes, no one has yet shown that 

 JLophiira ariiiata Kuetz. is same as Rhodomela' crassicaulis Harv. 

 And if my Identification proves to be correct the latter plant must be 

 called Choudvia ( Chondriopsis) crassicaulis (Harv.) J. A<^. accorclinp- 

 to J. Ao-arclh's opinion. But this species-name may cause contusion 

 with Chondria crassicaulis Harv., an indigenous plant, and so here I 

 think the name of Chondria armata (Kuetz.) Okam. may be preferable 

 to Chondria crassicaulis (Harv.) J. A 9-.
