The colony is an extensive white sheet overgrowing worm tubes. It is white in preservative. Stellate branchial apertures with a margin of spicules are arranged around small intensely white unperforated areas of the surface. Deep primary common cloacal canals extend the full length of the zooids and surround circles of zooids with their ventral surfaces embedded in ligaments of test between the surface and base of the colony. Small spicule-filled papillae are crowded on the surface between the branchial apertures. An even layer of relatively crowded spicules is in the surface test and another less crowded layer is on the base of the colony. Spicules are sparse elsewhere. The spicules are small, stellate, to

Zooids have a tulip-shaped branchial siphon and a large bifid atrial tongue. The branchial sac is large, but the stigmata could not be counted. Three coils of the vas deferens surround four or five testis follicles, the outside coil encircling the base of a large egg. Larvae being incubated in the basal test have a trunk

The larval pharynx does not appear to be perforated, although the gut is differentiated and the otolith and ocellus are present. Blastozooids were not detected.

The newly recorded colony is soft and flexible, possibly due to the small spicules and the deep common cloacal cavity. They are whitish black in life with white rims around the common cloacal apertures. In preservative the colony is brownish grey on the surface, with white points where the spicule-filled lobes of the evenly spaced, stellate branchial apertures open to the surface. Linings of the branchial apertures are black owing to the pigment in the superficial layer of test that turns in to line the siphons. The pigment in the superficial layer of test is mixed with the small spicules and overlies a non-pigmented layer of test. Zooids cross the deep horizontal common cloacal cavities singly or in clumps with dark pigment and sparse spicules mixed in the test connectives that surround them. The abdomina especially are encapsulated in black pigment cells in the test. Common cloacal cavities do not penetrate the test posterior to the zooids, and the basal test is opaque and white with crowded spicules. Spicules are small (to

thick with rounded margins and is smooth on the upper surface. The surface layer of test is thin. The common cloacal cavity is a horizontal space with thoraces crossing it in their own ventral strip of test. Abdomina are embedded in the relatively thick basal layer of test. A single sessile common cloacal aperture is on the surface. Spicules are crowded throughout the colony. They are relatively uniform with five to seven, and occasionally nine short, rod-like rays in optical transverse section. Zooids have a small thorax with a sessile atrial aperture without an atrial lip and a relatively large abdomen containing a long, curved gut loop. A long, tapering retractor muscle projects from about halfway down the oesophageal neck. The undivided testis is surrounded by seven coils of the vas deferens.
