JRemark on the determination of the spedes. There can be 

 no doubt as to the identity of this species. The figure by Kiitzing 

 1. c. is from a specimen that he got from Philippi himself, and 

 it on the other hand accords well with Hauck's description and 

 figures. Through the kindness of Mad. A. Weber van Bosse 

 I have had the opportunity to examine three authentic specimens 

 from Hauck's herbarium. Two of these nearly coincide with fig. 

 1 and 3 1. c., the above f. typica, and the third one forming 

 transition or most nearly related to f. capitellata. The species 

 seems to be rather varying and probably includes more forms. I, 

 however, have seen but some few specimens. 



Remark on the form and addition to the descpription of the 

 species. The form that I apprehend as the typical one is densely 

 branched, but the branches appear to be rather thin and apparently 

 less anastomosing, probably most often only in the lower or inner 

 part, always, however, thickening towards the apex, and especially 

 here often somewhat compressed, with the ends frequently rather • 

 obtuse or nearly truncate, or even depressed in the centre. This 

 form has not been found with us. 



A solitary specimen from Mandal nearly agreeing with fig. 2 

 by Hauck 1. c. I refer to the above f. capitellata, as well as 

 another one found washed ashore at Kragero and scantily provided
