It is very doubtful whether this should not be called Lagenipora 

 Costazii, Aud., for though the operculum is somewhat longer 

 and thicker, it is of the same type as that of the Mediterranean 

 L. Costazii. MacGillivray certainly seems to have made a slip 

 when describing C. Costazii^ from Victoria, for his species has 

 a small central avicularium below the mouth, and has not, as a 

 rule, the pair of long elevated avicularia. L. rota, on the other 

 hand, has the pair of avicularia, and very closely resembles the 

 European L. Costazii. Some authors have been misled by the 

 mistake now pointed out.

Zoarium pisiform. The differences from typical L. lucida, 

 Hiucks, are but very slight ; but as the present form more 

 nearly corresponds to MacGillivray's figure than is the case in 

 most specimens of L. lucida, attention is called to the fact. It, 

 however, has 10 tentacles, whereas the L. lucida from Madeira 

 has 12, and the mandibles of the vicarious avicularia differ some- 

 w^hat from those from Madeira, as the sides are straighter. The 

 ^vicularian tube is usually median, but is sometimes diagonal as 

 figured by MacGillivray. The ovicells are globular, with a very 

 small area. 



Lagenipora lucida is widely distributed.

The zoarium starts from a very small stalk, then spreads out, 



forming a club-shaped colony. 



The zooecia are jDorforate, having a few large pores, porcel- 



lanous, with a long rostrum supporting at the end a triangular
