In their recent work on the Godiaceæ of the Siboga Expedition 

 Mr. & Mrs. Gepp discuss the Chlorodesmis comosa of Maze et 

 Schramm, which in their opinion is an undescribed species of 

 Derbesia. It is possible; when I collected my above-mentioned 

 sterile plant I also took it for a Derbesia. When Mr. & 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 di- 

 chotoma.

In her "Phycologia Barbadensis", Pl. VI, M Ue Vickers has 

 figured an Enteromorpha which she refers to Enteromorpha torta

Reinb. 1 ) Having now found this, it seems to me, very character- 

 istic form also in the Danish West Indies and having examined it 

 in detail, I have arrived at the conclusion that I cannot agree with 

 M lle Vickers in considering the plant in question as belonging 

 to Reinbold's species. Major Reinbold has been so kind as 

 to send me several specimens of his species; when compared with 

 these and with the original specimen of Jürgens in u Algæ aqua- 

 ticæ", Dec. XIII, N. 6 the present form shows great differences.
