Bor.-Americana", Part II, p. 228, tab. XXXV, A. Gr. glohulifera 

 {Harv. in litt.) Kiitzing, "Tabulas Phycologicse", 1862 vol. XII, p. 10, 

 tab. 30. Gr. Bornetiana Farlow, "The marine Algoe of New Eng- 

 land", p. 181, pi. X, fig. 4, pi. XI, figs. 3 and 5. 



As to the name of the plant I would remark that it seems to 

 me that we may use the name first given by Harvey in "Nereis 

 Bor.-Americana". 



To be sure Farlow, when describing Gr. Bornetiana., was the 

 first' to give us a good and exhaustive description of the plant. 

 And on the other hand I willingly admit that Harvey's descrip- 

 tion of his var. globifera is rather defective as he has not at all 

 understood the male plant, in spite of the fact that his description 

 of the species and also the name of the plant highly refer just to 

 the male plant, as is also pointed out by Farlow (1. c. p. 131). But 

 Harvey also describes the female plant and he gives a rather 

 good figure of the plant in question, so I do not think we are 

 justified in not taking his description of the species for good and 

 use his name just as J. Agardh has done in "Epicrisis". A dif- 

 ficulty against the use of the combination Gr. globifera (Harv.) J. 

 Ag. is that in Kiitzing: "Tab. Phycol." 1. c. we find this species 

 called "Griffithsia globulifera (Harv. in litt.)." But is this name to 

 be considered as anything else but a slip of the pen from the side 

 of Kiitzing or Harvey for ''globifera'"^ 



This species characterized by its antheridial stands which were 

 first described by Far low, I have found in great quantities partly in the 

 sea around Buck Island north of St. Croix partly also in the Sound 

 between St. Thomas and St. Jan. In the North Atlantic it is 

 known from the shores of Massachusetts down to New Jersey. 

 Here it is a summer plant while in the West Indies I have found 

 it in the months February — March. Is it not certain that it has 

 been found earlier in the West Indies. To be sure it is reported 

 from Barbadoes in the list of algse from this island by Mile. Vi- 

 ckers but as pointed out by Lewis^) Professor Farlow does not 

 believe the specimens of Mile. Vickers to be identical with Gr. 

 Bornetiana. Professor Farlow has also by letter informed me that 

 he had written to Dr. B or net on the subject and the latter from
