An examination of the cystocarp, which I had not seen at the 

 time my list of Cape Algie was published, has convinced me that 

 the plant should be referred to the genus Pleonospovium rather than 

 to Arutothcmnion. In the above revised diagnosis I have been able 

 to add several important points to my former description.

Thysanocladia africana Schm. ( = Gelidium serratum Kiitz.). Port 

 Elizabeth, Farquhar ! The plant recorded in my list as T. coriacea 

 Harv. is Ptilophora j)innatijida J. Ag., under which name it is 

 recorded below. 



Hymenocladia kalymenioides mihi {= Microccelia kahjmenioides 

 Holmes). Port Alfred, SZrti^m ! liovfiQ, Becker \ Under this name 

 I place the plant previously recorded as H. jwhjmorplia J. Ag. Prof. 

 Schmitz pointed out to me that it was a new species of Hymeno- 

 cladia, but, before it was published, a plant was described by Mr. 

 Holmes as Microccelia kalymenioides in Annals of Bot. vol. viii. 

 p. 339 (Sept. 1891). Mr. Holmes there states that it is the 

 opinion of Prof. Schmitz that his plant belongs to Hymenocladia
