Sved., C. repens Crouan and C. divaricatum A. & E. S. Gepp 

 (non Holmes). Of them, the present plant seems to me to show 

 some affinities with C. repens Crouan on account of the creeping 

 habit and longer, narrow, ond clavate utricles of the latter as 

 A. & E. S. Gepp mentions under Codium divaricatum A. & E. S. 

 Gepp (The Codiaceae of the Siboga Expedition p. 136). Of that 

 species, however, I know nothing but Vickers' description of it 

 (Liste des Algues Marines de la Barbacle p. 56, no. 37). C. repens 

 seems to be very slender as A. & E. S. Gepp mentions under C. 

 divarication that the latter (which has segments 1.5-0.5 mm. broad 

 in dried state), resembles the former species in dimensions (A. & 

 E. S. Gepp 1. c.). Moreover C. repens is described by Vickers as 

 tubulous (" tubuleuse "). Of C. dimorphnm Sved. there is no need 

 to tell much of its difference from the present plant. Thus the 

 present species is different from all of those three related species.
