two circles of five large and 15 smaller ones of varying size inside these. Body wall deposits of sphere and proboscis comprise a superficial layer of tables lying outside a layer of large, smooth multilocular, imbricating plates plus other smaller, also multilocular plates interspersed amongst them. Table discs cup-shaped with the rim denticulate and turned up to give to some tables a cup and saucer appearance in lateral view; spire of moderate height, of four pillars, a single cross bar, terminating in a rather ill-defined crown.

. Colour, in alcohol, proboscis creamish, sphere creamish-grey proximally, uniformly creamish at base. Tube feet very reduced, in two zigzag rows per ambulacrum, extending to the tip of sphere with mid-ventral ambulacrum crossing pole of the sphere. Mouth and anus set very close together, difficult to distinguish, the latter surrounded by anal papillae. Tentacles about 20, in two circles of five large elongated ones plus about 15 smaller ones of varying size; branches much reduced. Proboscis rigid, sphere not as soft as in other rhopalodinids. Both sphere and proboscis rough to the touch due to the presence of tables superficial to the large imbricating plates whose free ends are directed anterioriad with the perforations so aligned to give the impression of some sort of regular sculpturing on the surface.

Polian vesicle single; stone canal short, madreporite minute, beanshaped. Each respiratory tree subdivided into two well developed branches of which one is longer and attached to body wall. Gonad (ovary) much branched, full of developing or developed eggs, with the longer branch of the right respiratory tree intermingled with it.
