Mr. P. H. Gosse on some new British Sea- Anemones. 193 



clothed with a tough epidermis, rough externally, firmly adherent 

 to the skin. Name from 0eX,Xo?, the cork-tree; also its bark. 



Sp. 1, Phellia murocincta (mihi). Epidermis free and tube- 

 like at the upper part ; its surface not warted. 



General Description. — Form. Base adherent to rocks, slightly 

 exceeding column. 



Column cylindrical, pillar-like when expanded, slightly grooved 

 longitudinally, smooth, but partly clothed with a dense, rough, 

 membranous skin, which is firmly adherent from the base about 

 halfway up, but there becomes free, forming a loose firm sheath 

 or tube, from which the animal protrudes its fore parts in exten- 

 sion, and into which it retires, at will, more or less completely. 

 Surface of epidermis rough, but not warted. Height, in full 

 extension, double the diameter. 



Disk a deep cup, bounded by the thick feet of the inner 

 tentacles. 



Tentacles twenty-four, in two rows, twelve in each ; those of 

 the first row twice as large as the others, with which they alter- 

 nate : variable in form, sometimes strongly conical, stout at the 

 foot, and pointed ; at other times nearly cylindrical and obtuse : 

 they have a tendency to assume a knotted appearance : they are 

 generally carried hanging over the margin with a double curve, 

 like the branches of a chandelier ; but sometimes those of the 

 inner row stand erect. 



Mouth not raised on a cone. 



Acontia (not observed). 



Colour. Column : exposed portion having a mealy appear- 

 ance produced by a number of whitish longitudinal lines and 

 dashes, more or less speckled and interrupted by the ground- 

 colour, which is pellucid yellowish grey. Of these lines, twelve 

 are broader, and between these are about four slender lines in 

 each interspace. The margin becomes deep buff, producing a 

 depression of that hue, when in the button-state. 



Epidermis pale buff, studded with dirty foreign matters. 



Disk dull bufi^, marked with a white star, which is formed by 

 a forked line proceeding from the front of each primary tentacle 

 towards the mouth. A broad white gonidial band on each side. 



Tentacles dark brown, pellucid, crossed by three narrow remote 

 rings of white. Where the foot of the tentacle unites with the 

 disk, its radius has a white patch, succeeded by two parallel, 

 longitudinal, black dashes. 



Mouth rich bufi^. 



Size. Diameter of column one-eighth of an inch; height 

 one-sixth ; expanse of flower one-sixth. 



Locality. Overhanging rocks and sides of caverns near low- 

 water mark, around Torquay.
