One form (my collections nr. 1364) had a habit rather like 

 the figures of M"'' Vickers, but some of the utricles were up to 

 350 fj- thick and among these some smaller ones often not more 

 than 90/.£ diam. occur; and as these thin utricles were also found 

 bearing sporangia I think they have been full grown. The thick 

 sporangia were about 3 times as long as the diameter. 



Some other specimens (nr. 1962) of which one was richly 

 proliferous had some very irregularly shaped utricles, more or 

 less jar- or barrel-shaped, the apices of the utricles were broadly 

 rounded, one utricle was ending in a point, reminding one of C. 

 mucronatum. Also the size of the utricles was very variable from 

 80 (i diam. up to 200 — 300 n and more, a single one was found 

 reaching even 600;^ in diam. 



Other specimens again were rather like the figure of M'^'^ 

 Vickers but the utricles were often a little too thick up to 320 /i. 



This species was found both in shallow water in a rather 

 exposed locality and in deep water down to a depth of about 

 30 — 40 meters. 



It was found, St. Croix: Coakley Bay on the east end of the island. 

 St. Jan: in the sea round this island: off Cruz Bay, off America Hill, off 

 Annaberg.

Some few specimens were found ; the whole plant was nearly 

 terete also at the dichotomies ; it was only very little narrowed here. 



Utricles, obovate-clavate, about 400 « diam., four times as 

 long as broad. 



Found at St. Jan: OiT America Hill in a depth of about 30 meters.
