of the Smooth Anemoae (Actinia mesembryanthe- 

 munij are seen ; both are of the common dark crimson 

 variety, the one being contracted, the other expanded : 

 the latter displays its petal-like tentacles, and the 

 curious azure tubercles that stud the margin. Around 

 the edge of a projecting rock on the right hand is 

 creeping Doris pilosa, a pretty white species of the 

 Nudibranch Mollusca. 



Behind this is a tuft of the elegant Griffithsia 

 setacea ; and a much-cut frond of the delicate Dictyota 

 dichotoma rises from the rear of the Anemones; 

 while, in the left-hand corner of the foreground, is 

 that coarse shaggy plant, the Gladojphora arcta.
