In preservative, the colony is a robust, brown slab. The surface has a regular quilt-like pattern of bolster-like elevations, which comprise about one-quarter of the total thickness of the colony and are separated from each other by deep narrow depressions.

apart are on the surface between the surface elevations. A thick spicule-free superficial bladder cell layer containing brown pigment cells covers the surface elevations. Similar brown pigment cells surround the zooids, lying free in the space between the test and the body wall of the zooids. Spicules are in a layer beneath the superficial bladder cell layer, but are completely absent from the translucent basal half of the colony. A thin layer of test forming the roof of the deep common cloacal canals is at the base of each of the surface depressions and the branchial openings of the zooids are along each side of the base of these depressions. The common cloacal canals are deep, extending at least the full length of the zooids (about three-quarters of the depth of the colony). Spicules are of moderate size with five to seven long, narrow pointed arms in optical transverse section. The ray length/spicule diameter ratio is about 0.5.

The posterior atrial siphons, each with five minute pointed lobes around the aperture, open into each side of the top of the common cloacal canals. Abdomina are large with a relatively voluminous gut sometimes forming a vertical loop and sometimes with the post-pyloric part bent at right angles to the longitudinal axis of the zooid. Five coils of the vas deferens surround about five or six large testis follicles.</paragraph>
