The manner in which the egg-laying proceeds in any single proglottid thus placed in sea-water is a very interesting thing to watch. Extreme writhing movements of a quite definite sort begin at once. The proglottid bends along its axis of breadth until it is almost a closed ring, the pointed anterior end some- times passing into the angle made by the posterior flaps (Fig. 2) and thus reminding one of an acrobat who could bend backward until his head should be thrust between his legs from behind, then the proglottid straightens and the bend is reversed, it uo. uo.
