It serves so well as a basis for explanation of various phenomena that it must at least receive consideration. I hope at some future time to

They may be entirely incorrect but I think the hypothesis of the effectiveness of circulatory currents as localizing formative stimuli cannot be rejected off-hand. It serves so well as a basis for explanation of various phenomena that it must at least receive consideration. I hope at some future time to obtain experimental evidence regarding this hypothesis. The second possibility, viz., that the change of form may be an incidental result of the movements of the animal must also be considered. As noted above, the behavior of typically distended specimens is very different from that of the same pieces during collapse. The creeping habit of Cerianthus is well known ; the animals are able to move about freely, lying upon the side and moving with either oral or aboral end in advance. They move not only on horizontal surfaces, but are able to climb the vertical sides of a glass jar or aquarium. In my aquaria specimens often.
