of the Smooth Anemone (Actinia mesembryanthemum) 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 Cladophora arcta.
