ILYANTHID^. 
Locality. 
The Menai Strait, in North Wales, and the Channel Islands; between 
tide-marks. 
Varieties. 
Specimens differ considerably in the depth and extent of the brown 
tints of the upper parts. In some the mai’onne or red-brown hue 
extends across the disk; in others it is scarcely discernible on the 
tentacles. 
The present species has generally been supposed to he 
identical with that of the Mediterranean, of which M. Jules 
Haime has given an elaborate memoir (Ann. d. Sci. Nat. 
Ser. 4, i. 341). But in that species the arrangement of 
the mesenteric septa, — which M. Milne Edwards (Hist. 
Nat. des Coralliaires, i. 308) gives as generic, differs so 
importantly from what obtains in ours, as to demand a 
revision of the generic characters. I have therefore con- 
stituted it a new species, naming it after Mr. W. Alford 
Lloyd, to whose intelligent enterprise the study of Actino- 
logy is so greatly indebted, and to whom we owe our 
acquaintance with this very animal. 
In the summer of 1856, this gentleman first obtained 
specimens from the Menai Strait, a fact which I noticed in 
the “ Annals N. H.” for July of that year, assigning the 
species to the Edwardsia vestita of E. Forbes. Mr. Lloyd 
also himself about the same time communicated two notes 
on the animal to the Zoologist,” in one of which he stated 
that he had then obtained eighteen specimens. Since that 
period he has procured many more, but, as I believe, only 
from the same locality. Some of these specimens he has 
courteously presented to me, and has thus enabled me 
to become personally familiar with the habits of the 
species.
