Wlien I first described this genus I believed that the polypes were 

 " scattered over the upper surface of the pinnae ; " but that is a mis- 

 take which I was led into by the imperfect state of the specimen : 

 the polypes are only placed on the margin of the pinnoe as in other 

 PennatuUdce.
