Juvenile colony triangular in outline, sharply tapered proximally, broadest at the straight distal edge; broadly club-shaped, with autozooids on both faces and along the edges; apparently budded from a single ancestrular zooid, anchored in (presumed) soft sediments by three thick, cylindrical, annulate rhizoids, each arising from a frontally modified autozooid, within three astogenetic generations of the ancestrula; distal ends of rhizoids finely divided into coiling tendrils.

the largest colony. Autozooid shape varies in relation to astogeny, in the first few generations oval to hexagonal, longer than wide; broadly hexagonal and wider than long in later generations; each bounded by a thin cryptocystal rim and separated by a distinct suture. Cryptocyst flat, calcification coarsely and evenly nodular. Opesia in distal half of autozooid, wider than long, with a thickened, raised rim, proximal edge straight in early ontogeny, later distinctly convex, with a narrow shelf within, produced close to each proximo-lateral corner into a short, blunt denticle; two opposing denticles present on the distal rim, in some zooids with a thickened ridge linking them; all denticles most pronounced in later astogeny. Endotoichal ovicells evident as low swellings on the cryptocysts of the two succeeding autozooids, with low crescentic aperture immediately distal to, and only slightly smaller than the opesia of the brooding zooid. In each of the triangular juvenile colonies the broad distal edge is capped by flat, polygonal kenozooids, each with a minute central foramen. In the two smallest specimens the distal edge of the colony was bounded by membranous body wall, with a new generation of partially budded autozooids visible beneath it. No avicularia noted. Proximalmost autozooids bear convex plates of cryptocystal calcification projecting above the frontal shield, from the proximal edges of which the rhizoids originate. In some marginal autozooids of the larger colonies the opesia is partially occluded by smooth calcification.

A number of these larger specimens retained their proximal portions, which were identical to the triangular juvenile colonies. Many of these colonies showed one or more growth checks. Autozooid morphology in these large specimens was closely similar to that of the small colonies; autozooids were proportionately broader towards the colony margins, but dimensions of the opesiae were the same, although the denticles were more pronounced. The largest complete specimen, ancestrulate and with undamaged growing edge was
