This is a very old species, but one whicii has caused more trouble lo 

 systematists than any other in the group, owing to the fact that tlie spicules 

 have hitherto never been investigated. The descriptions, based on a few 

 superficial characters, are so vague tliat on those alone it is possible to 

 identify almost any branching Gorgonella with this species.
