Gonosome. — Gonophores growing from the hydrorhiza, almost sessile; gonangia broadly oval in gen- 

 eral shape but narrowing distinctly just below the rim, which is expanded, so that it appears to have a 

 distinct but very short neck. 



Distribution. — Very common on the sargassum that drifted in to Bogue Bank and even into Beau- 

 fort Harbor. 



The gonosome has not been described for this species imder this name but it seems probable that 

 this is the species that Congdon has described as C. simplex," the gonosome being figured and described 

 and also the species that Hargitt has described as C. volubilis.b The fact that in both cases the speci- 

 mens were found on the sargassum makes it even more probable.

Genus GONOTHYRiEA. 



Trophosome. — As in the family. 



Gonosome. — Gonophores giving rise to sporosacs which are provided with short filiform tentacles. 

 Before maturity these sporosacs pass out of the gonangia but remain attached to the top until the planulae 

 are liberated.
