Beneath the bladder cell layer (at branchial siphon level), spicules are crowded throughout the colony. Except for a small plug of spicules in the lining of each branchial siphon, they are absent over the anterior end of each zooid. When seen from the surface, this interruption of the crowded spicules by the zooids appears as a network pattern beneath the superficial bladder cell layer. Otherwise there are no special features on this flat, smooth-surfaced colony. The common cloacal cavity is shallow, at oesophageal level. Spicules are relatively small (to
