I'art «\ tin- tnl>r of Telepsavus c The anterior \entral margin of the head projects through a central opening in the partition at the end of the rotation. This single opening is later reduced to two to four smaller openings as the secretory .surface of the worm is moved back and forth across the partition. "\Yliv the opening is not completely obliterated is not understood. Partitions are removed exactly as in Spiochaetopterus. The worm assumes a head-downward position in the tube. At the level of the jiartition the body is flexed dorsally 1S()'J so that the angle of flexure is located at the 4th parapodia. The flexed region of the body is now rotated a little to one side, Usually toward the left.
