colour encircled with an azure blue line, often streaked with red. 
The tentacula are.terminated by a small pore. Its colour is variable, 
but generally it is of a violetred. Sometimes it presents round 
spots of a fine green; at other times it is only of a greenish hue; 
the edge of the feet have a narrow border of red, with green and 
blue beneath, 
The verrucous or warty section of the Actiniad@ have the lateral 
walls of the column covered with warts. To this section belong the 
Dahha Wartlet, Zzalia crassicornis (Johnston), with its many varieties. 
Hollard describes them as frequently buried in the sands on the 
shore ; while Mr. Cocks describes them “as attaching themselves to

shells and stones in deep water, or attached on the littoral to the 
sides of rocks, in crevices, or on the face of clean stones in sheltered 
places.” The body is variegated, green, and red ; the tentacles thick, 
short, and greyish, with broad roseate bands. 
Coming now to the section where the base is not adherent, we 
find anemones with the base small, and terminating in a rounded 
point, and the body much elongated, as in Ldwardsia calimorpha 
(Fig. 74), in which the body is non-adherent, somewhat worm-like, 
having the mouth and tentacula seated on a retractile column, the 
lower extremity inflated, membranous, and retractile. 
Milne-Edwards also forms a special group of the genus PAyllactis. 
In this group the polyps are simple, fleshy, and present at once 
simple and composite tentacula. Such is Phylactis pretexta (Fig. 75), 
which is found in the neighbourhood of Rio Janeiro. The anemone
