Fig. Actinia sociata (Ellis'). Zoanthus (Cuvier). {After Ellis.) Family 6. — ACTINIADJE. Body soft and fleshy, free, mouth furnished with several rows of simple or branched tentacula. Actinia (fig. 45) Lucernaria, Moschata, Ac- tinecta, Discosoma, Actinodendron, Me- tridium, Thallasianthus, Actineria, Acti- noloba, Actinocereus, &c. Family 7. — Animals po- lypiform, with eight pinnated tentacles, more or less prominent, and regularly arranged upon a part only of a common polypary, which is free or adherent. Its form is deter- minate, and it is composed of a central axis, which is solid, and enveloped in a fleshy cortex, often of considerable thickness, and supported by calcareous aciculi. Pennatula (fig. 4-4), Renilla, Virgularia, Scirpearia, Pavoniaria, Veretillum, Om- bellularia. Sub-class 3. AULOZOA* (nobis), (Tubular Polypes.) Animals simple or compound, occupying the interior of corneous or calcareous tubes, which are either simple or ramified ; polypes terminal or lodged in lateral cells ; repro- duction multiform. Family 1. — Animals gene- rally aggregated ; polypes terminal, not retrac- tile ; reproduction by ova produced near the bases of the tentacula, and unenclosed in any cell ; polypary pergamentaceous or corneous, simple, tortuous, or regularly ramified ; some- times wanting; tentacula, numerous, solid. Tubularia (jig. 48.), Endendrum, Pennaria, Syncoryna (fig. 47), Coryna, Hydractinia, Stipula. Family 2. — TUBIPORIDJE. Polypary com- posed of calcareous tubes, arranged in succes- sive stages like the pipes in an organ ; po- lypes terminal, with eight pinnate arms. Tubipora (fig. 52). Family 3. — SERTULARIDJE. Polypes hy- driform, provided with simple tentacula, which are never ciliated ; lodged in lateral cells of variou
