Figure 8E, F View FIGURE 8 ; Figure 9 View FIGURE 9 A–C

#2655A, colony 7.5 cm across. Tunic pale reddish, almost completely covered with fine whitish sediment. Zooids embedded in common tunic, only the separate siphons emergent. Small tubercles around edge of siphons. In the living colony the siphon lining has red striping. A large zooid out of tunic 3 cm long with wide gut loop, many narrow plications on stomach, no caecum. Rectum very long, anus with 14 rounded lobes but also bilobed. Gonads six on left, 34 on right, very loosely attached to body wall, elongate and sausage shaped. No endocarps in gut loop or body wall. With small Pyura curvigona Tokioka, 1950 (#2655B) embedded in colony (see Fig. 11E View FIGURE 11 ).

Distribution: New Caledonia, Majuro, Australia, Hawaii.
