Mr. Gossp, in liis " British Sea-Anomonos nnd Corals," remarks that the Lncemaviailte have closer atlinities witli tlie ^Medusa^ than witli the Actinite, on account of several structural peculiarities, among which may he mentioned the gelatinous texture, the expanded umhrella, the egg-sacs in the suhstance of the umbrella, and the squared mouth at the end of a free footstalk. I have, therefore, departed a little from tlie ordinary arrangement, and placed the Lucernariadai immediately after the Acalephs, forming a kind of intermediate link between them. The highest form of true Zoophyte is, undoubtedly, that Mhich is so familiar under the name of Sea-Anemoneâa name singtdarly inappropriate, inasnmch as the reseniliiiuice to an anemone is very farfetched ; while that to the chrysanthennnn, daisy, or dandehou is very close. These creatures fire called Actinoida, and arc easily distinguished liy having the stomach inclosed in a sac divided into compartments by radiating iiariitions. For convenience .sake, this group is divided into two sui)-orders, the first of which is the Actinaria, known by the nundjer of tentacles (twelve or more), perforated above, and tlie radiating partitions sonu'times dejiositing solid chalky plates, commonly called "; The tribe Astraiacea is known Ijy the im]^>eriect series of tentacles, and the family Actiniada^ by their circular arrangement. The beautiful Oi'KLKT may easily be recognised by the great length of its many tentacles, which wave, and twist, and twine, and curl like so many snakes. It has but little ])ower of retracting the tentacles, and is, thei'efore, more conspicuous than many other species. It is tolerably hardy, enduring confin
