). The tunic is encrusted with fine sand, but allows seeing long double rows of zooids. The common cloacal openings are apical but some can also be found on the lateral sides of the lobes. It is difficult to extract the zooids from the resistant vitreous tunic containing thin mineral particles. The oral siphon has 6 lobes. The atrial opening is wide; it begins at the level of the 3th or 4th stigmata row to end at half-length of the thorax. The languet with 3 teeth is longer near the common cloacal aperture. The branchial sac has 18 to 22 rows of 10 stigmata on each side. The 5 stomach folds are not well marked; an annular post-stomach is followed by a short segment of intestine which forms the bottom of the digestive loop. The zooids have very long post-abdomens. Almost all colonies are immature. When present the testis vesicles have each a separate sperm duct joining the common duct at some distance, as previously noted in the description of the

). The oral siphon has 6 lobes. The rim of the atrial aperture is cut in languets. The branchial sac has 10 rows of stigmata without parastigmatic vessels or papillae. The gut is very short. The smooth stomach wall sometimes shows longitudinal ridges due to contraction. The long post-abdomen extends far into the base of the colony. Numerous testis vesicles are gathered in a cluster in the anterior part of the post-abdomen and the ovary is included inside this testis bunch. Immature larvae are incubated in the peribranchial cavity: they have 3 well separated adhesive papillae circled by a continuous line of vesicles. The neural vesicle contains a single sensory organite.
