appears to have spicules most like the present species although they have more rays, and the common cloacal systems differ, the tropical species having zooids embedded in the surface test rather than in ligaments crossing the common cloacal cavity.

Colonies are extensive, thin sheets, hard and brittle with crowded spicules, brownish beige in life and pinkish mauve to reddish brown in preservative. The pigment is confined to the surface layer of test, where reddish pigment cells are mixed with spicules, absent only from the area around the evenly distributed branchial openings. The common cloacal cavity is shallow and thoracic.

The specimens differ from previously recorded material in their restricted common cloacal cavities with the abdomen entirely embedded rather than only partially embedded in the basal test as Kott (2001) reported.
