 The tentacula are terminated by a small pore. Its colour is varia.ble, 

 but generally it is of a violet-red. 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(2 have the lateral 

 walls of the column covered with warts. To this section belong the 

 Dahlia Wartlet, Tealia crasskoniis (Johnston), with its many varieties. 

 HoUard describes them as frequently buried in the sands on the 

 shore ; while Mr. Cocks describes them " as attaching themselves to

 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 Edwardsia 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 Phyllactis. 

 In this group the polyps are simple, fleshy, and present at once 

 simple and composite tentacula. Such is Phyllactis prcctcx fa (Fig. 75), 

 which is found in the neighbourhood of Rio Janeiro. The anemone
