In life the colonies look glassy with randomly distributed, embedded blue-black spots of pigment and, mixed with them and in the same size range, spherical white clumps of tightly crowded spicules. In preservative, the black and white spots persist in reddish brown colonies, which have a fleshy appearance. However, these colonies are especially tough, the translucent test is difficult to cut and the zooids are impossible to remove. The surface of the
<typeStatus id="5D5BAC8DDF4A6007FB9FC690D9B5FA9B" pageId="16" pageNumber="2470" type="holotype">holotype</typeStatus>
colony is elevated into a broad rounded ridge with a large circular, elevated common cloacal aperture at one end of the ridge. The superficial layer of test contains pale brown-orange pigment mixed with an even, but relatively sparse, thin layer of spicules. Spicules are even sparser in a layer lining the very extensive posterior abdominal common cloacal cavity and another thin, sparse layer of spicules is on the base of the colonies. Spicules are absent from other parts of the colony. The surface ridges are the result of thickening of the basal test.

In preservative, the newly recorded colony has blue-black piebald markings resulting from fine pigment cells beneath a thin, superficial layer of bladder cells. Spicules are present throughout the test but they are never crowded and they become sparser toward the base of the colony. Zooids have a number of male follicles surrounded by five coils of the vas deferens.

One colony (QM G308603) has large common cloacal apertures with frilled margins, along one side of the colony, at the outer extremity of each curve, suggesting that the slab may have been on a vertical surface, the margin with the common cloacal cavities being along the upper edge. Colonies are soft and gelatinous but quite turgid. Spicules are in a single layer in the surface, and in a sparse layer lining the vast central common cloacal cavity which has large vertical canals penetrating the surface layer of test around the zooids. The surface layer of spicules penetrates into the test that forms the rim around the common cloacal apertures but they are sparse in the remainder of the colony. One of the photographed colonies appears to have been black, although it is recorded in the collector’s note as brown (QM G308603). The other newly recorded colony appears to have been reddish orange. Both are colourless in preservative. The spicules are relatively small (to

Zooids are large, with false siphons formed by the velum in the base of the branchial siphon, short atrial siphons, fine longitudinal muscles in the parietal body wall, and especially fine and few muscles in the transverse sinuses between the rows of stigmata. The paired dorsal pharyngeal muscles, which generally are inconspicuous in this genus, were not detected at all in this species.

Also, the zooids have the characters previously identified as characteristic of this group of species, having a branchial velum at the base of the branchial siphon, numerous stigmata, a double curved gut loop and an S-shaped curve of the vas deferens over the outside of the testis follicles. The only departure from previously recorded specimens is the absence of the smaller almost globular spicules that Kott (2001) reported, although the attenuated points on the conical spicule rays are exactly like those previously described.

Colonies are encrusting sheets varying in colour from white with black spots or with patches of grey to an even black. In preservative colours are similar, though lighter, and black spots are in the grey areas. Sometimes the pigment is more concentrated in the surface grooves over the primary common cloacal canals that surround grey surface elevations over the solid stands of test (where the pigment layer is diluted by the depth of the white spicules in the upper part of the colony). The black pigment is in branching bodies in a layer beneath the surface, where it is mixed with spicules. Randomly distributed common cloacal apertures with frilled rims are at the junctions of the primary common cloacal canals. Spicules are crowded in a layer in the upper, zooid-bearing half of the colony, but are only very sparse in, or absent from, the lower half of the colony where the test is translucent. They are to
