396 POLYPI. 
The Polypi of the fresh water Tibularie+:Plamatehy Bosc. (1) 
—seem to be closely approximated to the Gristoialls 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, 
. TT. 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). 
Trpiana, Lamour, 
Zigzag tubes presenting a small open branch at each angle(4). 
Cornutaria, Lam. 
Where the tubes are conical, from eachof which issues a Polypus 
with eight dentated arms, like those of the Alcyoniz, Gorgoniz, 
&e.(5) In 
ANGUINARIA, Lam. 
The tubes are small, cylindrical and adhere to a creeping stem, 
(1) Lamouroux has changed this name to Narsa. 
(2) Tubularia campanulata, Res., UW, \xxiii—lxxvy;—T'ub. sultana, Blumenb., 
Man., Fr. Trans., II, pl. of p. 10, f. 9;—T'ub. lucifuga, Vaucher, Bullet. des Sc., 
Trm. An. 12;pl ax, 1: (6,'7.

Tub. trichovdes, 1d., \b., a;—Tub. solitaria, Rapp., Ac. Nat. Cur. XIV, xxxviii, 2. 
(4) Tibiana fasciculata, Lamour., Polyp. Flex., pl. vii, f. 3, a. 
Here, Lamouroux places Liacores, Terestio and Neomeris, subgenera which 
perhaps would be as well arranged in the vicinity of the hollow Corallinz. 
(5) Tubularia cornucopia. N.B. The pretended Tubularie of Esper, pl. xi— 
xxvi, merely represent the envelopes of ova of some Mollusca Gasteropoda, the 
eighteenth excepted, which isa Galaxaura.
