Bracts are very characteristic in shape (Text-fig. 21). The bracteal canal terminates on a papilla on the concave terminal facet. The presence of young bracteal buds of this characteristic form is the criterion for identification of large pieces of the siphosome, and at once distinguish such pieces from those of another antarctic physonect Stephanomia convolnta, whose young bracts have a terminal sausage-shaped mass of nematocysts lying in the sagittal plane of the bracts, separating the two oblique, dorso-lateral, terminal facets. The muscular lamellae of bracts and buds of bracts are closely crowded together in at least six rows on either side of the gonophores in the contracted and preserved material, and most of the gastrozooids are 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 Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography of Great Britain; Great Britain.
