Akimal. Unknown. 



Locality. 



The Moray Firth, deep water. 



For this very distinct and remarkable little Coral I am 

 indebted to Mr. James Macdonald, of Elgin, who obtained 

 it from Lossiemouth, in October, 1858, attached to a valve 

 of Cyprina, from the deepest part of the Moray Firth. 

 There is no other species with which it can possibly be 

 confounded, the expansions of the ribs presenting a very 

 striking character. They remind me of the immense but- 

 tresses which surround the base of the giant Ceiba of the 

 Jamaican forests. To this feature I have alluded in the 

 specific name, which is formed from 7rrepov, a wing, and 

 7roi)?, a foot. 



My friends, Messrs. Macdonald and Gregor, speak of 

 other Corals having at various times come under their 

 notice, but they had always been set down, like these now 

 recorded, as Caryojphyllia fimithii. It is by no means 

 improbable that further research may considerably aug- 

 ment the list of our living Corals.
