inferior (Fig. 9 B and G) of almost the same oblong — cordate 

 shape, with a rather deep sinus in the end turned outwards, deepest 

 in the corona superior. Corona superior has two hair-scars one 

 behind the other. 



Rather a large number of gametangia (about 200) were found 

 in the rays of one of the specimens; they were about 60// broad, 

 but I may mention that the plant was yet quite immature; the 

 calcareous massula in which the gametangia ought to be embedded 

 I was unable to see in this specimen. 



This species was found: St. Croix, at Longpoint most probably 

 in shallow water; St. Thomas, the lagoon of Bovoni in shallow 

 water; St. Jan, off Cruzbay in about 30 meters depth (only one 

 specimen found), and off America Hill in about 16 meters depth 

 (only two specimens found).
