To the right the young shell exactly resembling Buccinum ; to the left the old shell firmly attached to the branches of Anli- pathet by its irregularly formed margin- it. The shell throws out processes in every direction, by which it clings to the coral, in the mode here shown in a woodcut copied from Steenstrup, till at last the mollusc loses all power of motion and lies, anchored as it were, to the Anti- pathes. Of what use this can be to the animal it is difficult to say; but we may venture to put forward the hypothesis that it must be, and is, of some service, and also that an originally accidental connection and growth of some true species of Buc- cinum with the slender branches of a Gorgonia must have given rise to this extraordinary habit. Certain parasitic offer another example of such a peculiar action of one animal on another. The species of Pel- togaster often live attached to the hind part of the body of the hermit crab, and they then assume the form necessitated by that.
