Zooids are mutilated, although they are seen to be long and threadlike with a long posterior abdomen and about 20 longitudinal folds in the wall of a small stomach. The atrial aperture is obscured and the presence of an atrial lip and its relationship to the aperture is not apparent. The specimen appears to be unidentifiable.</paragraph>

In this family, generic and species determinations are based on aspects of the morphology of the small, simplified and convergent zooids embedded in common test, often amongst crowded calcareous spicules. Spicule distribution is known to be adjusted to shade the colonies of a group of autotrophic species containing plant cell symbionts (see

suggested that the white reflecting surfaces of the calcareous spicules may lower the temperature in shallowwater habitats. It appears from species in the present collection that spicules are crowded together in the test of large branching and encrusting colonies to form a firm hard self-supporting colonies or a supporting skeletal framework through the central axis of the colony and its branches.

Identification at species level relies on variations in those characters as well as the structure and size of the calcareous spicules (which are not affected by the various artefacts of collection and preservation that affect the soft parts of the colony).</paragraph>

For instance, the pharyngeal walls of oesophageal buds and larval pharynges (both without well developed muscles) are not contracted and the number of rows of stigmata and the number in each row can often be readily detected in cleared preparations.</paragraph>
