The royal natural history . re is an ex-tended specimen, and near the rightedge a strongly contracted specimen ofthe lovely green Actinia carl. Other beautiful forms are found in the twostriped anemones, Ragactis pulchra and Gereactis aurantiaca. The sun-anemone{Heliactis bellis), again, varies greatly in colour but is always elegant, and thesame may be said of the trumpet - anemone with spotted tentacles {A^ptasiamutabilis). In the foreground at the centre a hermit-crab is seen carrying withhim his guest, the cloak-anemone (Adamsia palliata). A less conspicuous anemone(Eloactis mazelii) is provided with somewhat long cylindrical tentacles. TheAnemonia sulcata lets its tentacles float gracefully, while the vestlet (Cerianthusnibranaceus), of varying colour, hungrily stretches out its arms in all directions.Gladactis costaz, which is covered with warts, is no less voracious, but with apparentapathy allows its tentacles to droop around it.

Anemonesonly settle in places where the currents bring them the animal food they need;and are most plentiful where the current is strongest, as, for instance, at theentrance of harbours or on rocky coasts. Some species are in the habit of settlingon other animals whose requirements make the
