ILYANTHIDiE. 
Tentacles. Transparent and colourless, marked with spots and dashes 
of opaque white, ari’auged in in-egular transverse rows and rings, which 
increase in number and size until they become confluent towards the tips, 
which are thus pure white. The glassy translucency of the tentacles 
throws out these opaque markings with beautiful effect, especially as the 
foot of each is girded by a broad circle of white. 
SiZK. 
Column about three-quarters of an inch long when contracted, but 
extending to two and a half inches, with a diameter of one-fourth : disk 
one-fifth of an inch ; expanse of flower about one inch. 
Locality. 
The south-western coasts of England ; deep water. 
In the summer of 1853 I obtained, from about five 
fathoms in Weymouth Bay, a specimen of this species, 
which I described and figured in the Annals of Nat. Hist, 
under the name of Scolanthus, as I supposed it to be an 
unrecognised form. M. de Quatrefages had, liowever, pub- 
lished an able and elaborate Memoir* on a form Avhich 
he had named Edioardsia, in well-merited honour of the 
eminent French zoologist, M. Milne Edwards. On mature 
consideration, I was convinced that my Weymouth spe- 
cimen ought to be placed in this genus ; for though I had 
described a posterior orifice, which is wanting in Edwardsia, 
it is probable that I mistook, for such, the depression at 
which the phijsa, which I did not see, was retracted. The 
animal appears to be quite distinct from all of the three 
French species described by ]M. de Quatrefages, and to be 
well marked by its beautiful painting, which, resembling 
the inlayings of veneer-work, or the fignires of the kalei- 
doscope, suggested to me a name derived from /eaXo?, beau- 
tiful, and /jLopebr), form. The English term commemorates 
* Anualea lies Sci. Nat. 1842, Ser. 2, xviii. 65.
