ACTINIARIA. 
The trunk is of a greyish green or brown ; the disk is brown with 
greenish rays. This species is plentiful in the Mediterranean and 
in the Channel. When attached to the vertical sides of a rock, a 
kittle below the surface of the water, in which position it is often seen 
°n the shores of the Mediterranean, the tentacles hang suspended as ii 
the animal had no power to display them in their radiate for m , but 
^hen fixed horizontally in a calm sea, they are spread out in all direc- 
tions, and are kept in a state of continual agitation ; its long mane- 
iike tentacula, fully expanded, float and balance themselves in the water 
in spite of the action of the waves, presenting a most interesting spec- 
kle as it displays its beauties a few feet below the passing boat. 
A. diantlms (Ellis), having a number of synonymes, is represented 
in Pl. Y. Fig. 1 ; its body is smooth and cylindrical ; the disk marked 
I 11 the centre with clavate radiating bands; tentacula numerous, 
Regular, the outer small, and forming round the margin a thick 
filamentous fringe. This species attaches itself to rocks and shells 
in deep water, or within low-water mark, to which it permanently 
attaches itself, and cannot be removed without organic injury to the 
W. When contracted, the body presents a thick, short, sub-eylm- 
flri cal form, about three inches long, and one and a half m diameter, 
ail( l about five inches when fully expanded ; the skin is smooth, ot an 
Uniform olive, whitish, cream, or flesh colour. The centre of the disk 
18 ornamented with a circle of white bands, radiating from the mouth, 
tPe lamelke running across, the circumference being perceptible 
trough the transparent sldn. From the narrow, colourless inter- 
nees between the lamelke tbe tentacula originate. “They are 
Placed,” says Dr. Johnston, “between the month and the margin, 
^ich is encircled by a dense fringe of incontestable beauty, composed 
of innumerable short tentacula or filaments, forming a thick, furry 
bolder.” I a p L . y. Fig. 2 we have probably Gaertner’s Anthea cereus, 
i'ljo body of which is a light, chestnut colour, smooth, sulcated length- 
^ise, with tentacula rising from the disk to tbe number, in aged 
a uimals, of two hundred. Sagartia viduata — Gosse (Fig. 4) has the 
Tody adherent, cylindrical, without a skin, destitute of warts, emitting 
Ca Psuliferous filaments from pores; nettling- threads short, densely 
^'med with a brush of hairs ; tentacles conical. A. pida (Pl. IY. 
% 6), which Professor Edward Forbes changes to Adamsia palliata, 
18 described by Mr. Adams, who first discovered it, “as longitudi-
