Adjacent lobes are joined to one another here and there along their contiguous surfaces or by flat connecting bridges. Large rigid common cloacal cavities and canals surround the central test core and form a sponge-like, three-dimensional network of posterior abdominal canals. A hard, supporting, branched skeleton of crowded spicules is in the very centre of the test core of each of the vertical lobes. Otherwise spicules are not crowded, although they are present throughout the colony. They are in the superficial layer of test on the upper surface and lining the common cloacal cavity and these surfaces feel raspy to the touch. Spicules are large (to

Branchial siphons are about onefifth of the total length of the thorax with six small points around the rim of the opening. The atrial siphon is short, generally laterally directed, at the posterior end of the thorax. Eight rectangular stigmata are in the anterior row in the branchial sac, the number reducing to six in the last row. A large circular saucer-shaped lateral organ is conspicuously depressed into each side of the body just antero-ventral to the base of the atrial siphon. A short tapering retractor muscle projects from the posterior end of the thorax. The testis is undivided and the vas deferens is coiled seven times around it.</paragraph>
