Mature scyphistomae (Plate 1, Fig. B) had a mean height of 7.62 mm and a mean oral disc width of 2.45 mm (Table 4c). Tentacles were arranged in a single whorl (ranging from 30–44, mean = 38) around a slightly sunken mouth disc and a cylindrical, four-lipped hypostome. Scyphistomae were yellowishwhite to pale orange in colour. The calyx, perched on a stalk of medium length (44% of TBL), was slender and funnel-shaped. The widest body diameter was the mouth disc (70% of the calyx length). The basal disc and ca. 50% of the stalk were enclosed by a narrow, funnel-shaped periderm tube (

This involved typical lateral scyphistoma budding (at calyx and stalk junction, typically one bud per scyphistoma at a time), stolonal budding, and polydisc strobilation (Plate 2, Fig. B; strobilation rates: Table 5).

2, a new periderm tube was formed at the tip of the stolon. The old scyphistoma was dragged by the stolon from the old periderm tube, and a tiny tissue residuum remaining in the old tube died after a few days. The stolon was resorbed by the newly located parental scyphistoma.

Newly liberated ephyrae (Plate 3, Fig. B) had a total mean body diameter (TBD), from lappet tip to lappet tip, of 7.77 mm (range: 3.5–10.8 mm, Table 6c) and a mean central disc diameter (CDD) of 5.85 mm, which comprised about 57% of the TBD. Ephyrae had 13–18 marginal arms, flame-shaped and pointed rhopalial lappets, and a single rhopalium per lappet stem, situated between the two rhopalial lappets (Table 6c). Rhopalial lappets measured 53% of the total marginal lappet length (TMLL). The manubrium was of moderate length (≈28% of CDD). There were 1–2 gastric filaments per quadrant in the central stomach. There were 0–2 single tentacle buds above the velar canals. Ephyrae were yellowish in colour with a yellowishorange gastric system; white nematocyst clusters were scattered over the exumbrella.

The gastric system of newly-released ephyrae (Table 3e, Fig. “Stage 1”; Plates 4 and 5, Figs. A) consisted of a central stomach, 13–18 non-forked, arrow-shaped rhopalial canals, and 13–18 very short, non-forked, arrow tip-shaped velar canals. The tips of the rhopalial canals ended at the base of the rhopalium. The tips of the velar canals ended a short distance above the stomach. One or two single tentacle buds were present on the subumbrella above velar canal tips (Plate 4, Figs. B and F).

New canal connections formed by "Ausstülpungen" (= diverticula from gastric canals, defined by Stiasny 1921; Uchida 1926), others were disconnected by “Inselbildung” (= island formation, meaning the fusion of the roof and bottom of the gastric cavities, defined by Stiasny 1921; Uchida 1926).
