The terminal globe is filled with proportionally large oval vesicles, each with a central cavity, which are arranged in a divergent manner around the centre, so that their tips shall reach the sur- face of the globe; these are those potent weapons of offence called thread-cells {cnidm). The surface of the globe is covered with short thick palpocils, which Dr. T. S. Wright considers as prehensile organs. " These palpocils arise, each as a somewhat rigid process, from the side of one of the large thread-cells, buried in the head of the tentacle ; and they probably convey an impression from bodies coming into contact with them, to the thread-cell, causing the extrusion of its ; Besides these globe- headed tentacles, there are, on the lower part of the club-foot, four other organs similar in every respect, except that they are not furnished with heads, nor any terminal dilatation whatever. They project horizontally as the knobbed ones, but their ori- gin, and the respective lines of their radiation, are in- termediate or alternate; in other words, if we consider the globe-heads as pointing S. and W., the sim pie ones point , , , and From the carefully made observations of several 17*.
