from the short description given by Miss Vickers^) and it is also 

 rather nearly related to Chantransia Nemalionis (De Not.) Ard. et 

 Straf. (Rosenvinge 1. c. p. 12G) and to Ch. corymhifera Thur.^). 



This species has been found in shallow water in the small 

 lagoon at the head of the eastern bay in the harbom- of St. Thomas. 

 It occurred with monosporangia in the month of January. 



Nemalion Schramnii (Crn.) Borgs. 



Syn. Hehninthocladia Schrammi Crn. (nomen nudum) in Maze 

 et Schramm , "Algues de la Guadeloupe" S^ Edition. Basse-Terre, 

 1870—1877, p. 177. 



On the south side of St. Croix I have found some few but 

 large and well developed specimens of a Nemalion which I think 

 may be identical with Helminthocladia Schrammi Crn. in Maze and 

 Schramm's work on the algse of Guadeloupe. 



During a visit to Paris I have been able to compare, by the 

 great kindness of Dr. Bornet, my plants with the specimen of 

 Helminthocladia Schrammi Crn. found in Thuret's Herbarium; 

 and further I have had for comparison the specimen of the same 

 species preserved in the Herbarium of Museum d'Histoire Naturelle, 

 Paris. And finally during a visit to Lund I have been permitted 

 to examine the large specimen of Helminthocladia Schrammi be- 

 longing to the Herbarium of J. Agardh. 



As the result of these examinations I have convinced myself 

 that they all belong to the same species and are identical with 

 my specimens from St. Croix. In "Till Algernes Systematik", 

 6*^^ Afdelningen , p. 40 J. Agardh mentions this plant and arrives 

 at the conclusion that it seems to him very doubtful if it after 

 all does belong to the Floridese: "multo potius eam ad Chordariaceis 

 pertinere conjicerem; inter quas Genus proprium inter Eudesme et 

 Liehmanniam inserendum, forsan constitueret". Regarding the above 

 mentioned large specimen of his herbarium (No. 31962) J. Agardh 

 had here written: "Evidenter compressa, structura fere Helmintho- 

 cladice aut Nemalionis" ; this shows that J. Agardh had at that time 

 a better apprehension of the relationship of the plant in question.
