Metepora phcenicea, Busk, Brit. Mus. Oat. p. 94, pi. cxxi. figs. 1,2; 

 Hiucks, Ann. & Mag. Nat. Hist. ser. 5, vol. i. p. 363 ; MacGillivray,

The front of the zooecium has numerous large foramina, 

 the dorsal surface is divided bj prominent vibicse, and in 

 each division there are from one to four small foramina. 



There seems to be some mistake with Busk's figure of the 

 operculum, as it does not correspond with any that I have 

 seen. The mandible is without a lucida. 



This is evidently common, and Mr. Brazier speaks of its 

 being known bj his children as the '^ red coral."
