The apex of the hypostome carries a nematocyst pad (cnidothylacie) as do the terminal knobs of dactylozooids and gonozooids. Gono- zooids arise close to the bases of the gastrozooids (unless the colony is rapidly advancing as the tube grows). Dactylozooids, which never bear medusa buds, are found further from the rim than gonozooids, usually on longitudinal stolons. In sexual colonies there are eight medusa buds to each gonozooid, each bud being at a different stage in development. In advancing colonies the stolons run parallel at the terminal end of the tube leaving a stationary mat of anastomosing stolons covering proximal portions of the tube. More usually transverse stolons are found at the bases of gastrozooids anastomosing with longitudinal 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. ).
