At irregular intervals, one of the hydrothecse is replaced by a branch, so that the colonies assume an irregularly bushy appearance. The hydrothecas are fairly large, and when closed, about twice as long as broad; they are practically cylindrical, with evenly curved proximal part. Diaphragm lacking. Closing apparatus passes over without distinct limitation into the lower portion of the hydro- theca wall; it closes conically over the indrawn polyp. The gonothecse are set upon short, ringed stalks, projecting from the stem or branches beside the hydrotheca stalks. The gonothecse are small, slender, reversed conical or cylindrical with gradu- ally tapering basal part; they are cut off transversely at the distal end. The gonophores develope (according to Hincks) into free 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 Ingolf (Cruiser); Danish Ingolf-Expedition (1895-1896).
