Sometimes the exterior of the wall isfurnished with longitudinal PviBS (costce), which correspondto the plates. The plates are arranged in cycles : those of the firstcycle project furthest inwards; those of the second bisectthe interspaces; those of the third bisect the interspacesthus formed, and so on. The whole of the plates developedin one primary interspace constitutes a SYSTEM. In theTuRBiNOLiAD^E the corallum is solid (not porous),simple, with the lamellar interspaces reaching to thebottom of the cavity, and perfectly free. The plates arehighly developed, simple, and generally have a granularsurface. The ribs are well-marked. x 2 308 ANALYSIS OF BRITISH GENERA. With palules : adherent.

The animal (for so we may conventionally term thesoft tissues, though it is to be remembered that thecorallum is an essential part of the living body) is, sofar as we know it, translucent, the column very exten-sile, the disk protrusile, the tentacles set in severalrows, diminishing in size from the outer row inward,each consisting of a stem with a globular headNote About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
