tentacles thick, short, and greyish, with broad roseate bands. 
The Anemones belonging to the fourth 
section, or tap-rooted actinia, have the

r °unded point, and the body much 
elongated, as in Edwardsia, Calimor-

tremity inflated, membranous, and re- 
tractile. 
In the great family of the Actinia - 
rrans, Milne Edwards forms a special 
Sr°up 0 f f] le Phyllactin*. In this 
§r°up th e polypes are simple, fleshy,

tre rocks on the sea shore, and covers itself with sand. Its trunk, 
°1 cylindrical form, is of a flesh-colour, with vertical lines, having red 
P 01 nts. The interior tentacles form two simple elongated rows ; the 
exterior tentacles are spatulate and lobed, not very unlike the leaves 
of the oak. 
■Another group, that of the Thalassianthidse, is distinguished from

w hieh inhabits the Eed Sea. 
In the last group of Actiniad®, as arranged by Mihie Edwards, the 
P°Iypes occur in clusters, and are multiplied by buds, rising from a

creeping, root like, fleshy base ; they thus present a sort of 
^■niaoeous polypier, as in Zoanthus soeialis (Fig. 82). In the British 
nnnel this species, which Dr. Johnston has named Z. Couchii, after 
r ‘ Couch, jun., is found along the Cornish coast, on flat slates and rocks,
