Figure 22 in Taxonomic classification of the reef coral family Mussidae (Cnidaria: Anthozoa: Scleractinia)

Figure 22. Mussa and Scolymia microstructure (transverse thin section): left column, wall; middle column, mid-septum; right column, close-up of clusters. Both Mussa and Scolymia have parathecal walls (w); however, trabeculothecal elements and thickening deposits are better developed in Scolymia. Both genera form well-developed clusters of calcification centres (c) that cross medial lines. These clusters are more closely spaced in Scolymia. A–C, Mussa angulosa (Pallas, 1766); figured specimen = SUI102761 (FA1012), Bocas del Toro, Panama. D-F, Scolymia lacera (Pallas, 1766); figured specimen = USNM1090899, Bahia Concha, Colombia. G–I, Scolymia cubensis (Milne Edwards & Haime, 1849); figured specimen = USNM84939, Maria Buena Bay, Jamaica. J–L, Scolymia wellsi (Laborel, 1967); figured specimen = USNM84926, Angel Reef, Tobago.
