Show 396 POLYPI. The Polypi of the fresh water Tubularire-Plumatella, Bose. ( 1) -seem to be closely approximated to the Cristatellre by the dispo· sition of their Tentacula. Certain species are found in France, that creep over the plants of stagnant waters(2). TuBULARIA MARINA· . The Polypi of those that inhabit salt water have two ranges of tentacula, the outer one forming radii, and the inner turning up into a tuft. One species, T. indivisa, Lam.; Ellis, Corall., XVI, c, is found on the coast of France; its tubes are simple and two or three inches high, resembling pieces of straw(3). TIBIANA, Lamour, Zigzag tubes presenting a small open branch at each angle( 4). ConNuLARIA, Lam. Where the tubes are conical, from each of which issues a Polypus with eight dentated arms, like those of the Alcyonire, Gorgonire, &c.(5) In ANGUINARIA, Lam.
