The first of these is generally found in quiet bays where the shore is covered with large stones and pebbles, the individuals being sometimes attached to these and sometimes to cracks in the rock. As this species produces its young fully developed, and the newly-born actiniae are able to attach themselves easily, it is frequently met with in fairly large colonies. Another remarkable mode of propaga- tion, namely schizogony, is to be seen in Metridium diantJms in its younger stages. From the foot-disc of the animal small pieces unwind and form new organs, such as new tentacles, new mouth, etc. In this way colonies are formed, which may be widely distributed over the rock or the roots of the laminaria. ^ Chiefly Alcyonidiuin hirsiitum, Fliistrella hispida, Bowerbankia i?
