The arrow points to microfibrils which are oriented circumferentially about the ring canal rim. The canals contain mitochondria (m) and ribosomes ; (D.) an oblique section through a S4 ring canal. The arrow points to microfibrils in the rim Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
