During a visit to Paris (Oct. 1908) I was able through the 

 courtesy of M. Paul Hariot to examine a specimen of Maze & 

 Schramm's Algues de la Guadeloupe determined as Chlorodesmis 

 comosa and it seemed to me rather probable that this plant 

 was the male plant of Vaiicheria dichotoma. As now this speci- 

 men bears a great likeness to the sterile one I referred with 

 much doubt to A(^r. comosa in an earlier paper ^) I think it 

 very probably that my specimen belongs to this species. 



In their recent work on the Codiacese of the Siboga Ex- 

 pedition Mr. ct- Mrs. Gepp discuss the Chlorodesmis comosa of 

 Maze et Schramm, wdiich in their opinion is an undescribed 

 species of Derhesia. It is possible ; when I collected my above- 

 mentioned sterile plant I also took it for a Derbesia. When Mr. 

 i^' Mrs. Gepp describe the sporangia of Maze and Schramm's 

 plant as globose I may point out, that in the Paris Museum 

 specimen I found them obovoid much resembling in form the 

 antheridia of Vaucheria dichotoma.
