Cymbaloporetta ? sp. 1 ( Fig. 22 : 5, 6)

Remarks. Specimen assigned to Cymbaloporetta due to its slight dome shape with crescentic chambers that are coarsely perforated. Certain assignment was not possible for this species due to the limited number of material of only a single juvenile specimen attached to reef rubble, obscuring the umbilical side.

Distribution within study area. Only one specimen was recovered from Heron Reef flat, Transect 1 and was alive at the time of collection.
