TABLE 4. — As observed on the middle member of the Attard ramp: the relationship between taxonomic composition and structures of the rhodolith nucleus and of other types of structure outward. For each type of rhodolith structure on the nucleus and outward is indicated the percentage of rhodoliths in which each coralline species occurs.
