Together with the tj-pical form there occurs at Berufjord 

 a more elevated, conical, capshaped variety, which may 

 suitably be named elevata, Avith more or less concave under 

 side. The last character is probably due to their occurrence 

 on corals. It is connected with the type by a series of inter- 

 mediate forms and does consequently not represent a separate 

 variety.
