TYPE SPECIES. — Prismastrea organum n. sp.

DIAGNOSIS. — Phacelo-cerioid coral with polygonal corallites multiplying by intratentacular budding. Radial elements are subcompact, subconfluent, septa. Lateral faces of septa hold granules organized in carinae, typically montlivaltid in shape and distribution. Distal and inner edges are ornamented with trabecular teeth that sometimes project in the axial zone, producing a parietal papillose columella. No endotheca observed. Wall of unknown nature but precisely delimited and apparently of the same nature as septa. No synapticulae.

ETYMOLOGY. — Refers to the prismatic shape of the corallites.
