54^ ZOOPHYTA. SERTULARIADJE. Sertularia. 
Height scarcely an inch ; shape of the cells like a bull’s horn, the base nar- 
row, slightly curved and enlarging to the summit, when it is bent inwards to 
form a wide marginated orifice ; the bristle on the inferior margin is short. 
Gen. LXII. ANGUINARIA. — Stem adhering, irregular, 
cells scattered, tubular, produced, with the orifice on the 
side towards the extremity. 
16*2. A. angmna.—^iem branched, with irregular swellings, 
from which the cells arise.

march., Hist. An. ii. 143. — Actea ang. Lamour. Cor. Flex. 153. — On 
fuci, rare. 
Cells cylindrical, a little swollen towards the rounded and closed extre- 
mity, where it is slightly bent, on the upper side of which is a fiat, mem- 
branaceous, perforated space, the orifice of the cell. 
sertulariadj:. 
Gen. LXIII. SERTULARIA.— Cells-alternate, usually with 
a joint above and below each. 
163. S. polyzonias. — Loosely branched, cells smooth, not 
crowded, wide at the base, with a produced subtubular mouth. 
Great tooth Coralline, Ellis., Cor. 5. t.ii. f. 3 — S. pol. Linn. Syst. i. 1312. 
— S. ericoides, Pall. El. 127- — On dead shells and the roots of fuci, be- 
yond low water-mark. 
Height seldom above two inches ; more or less branched irregularly ; the 
produced cells give the branches a zig-zag appearance ; the margins of the 
orifices of the cells are irregularly notched, and in some large specimens they 
are slightly wrinkled across towards the summit ; the vesicles (as the ovaria 
have been denominated) are placed irregularly on the sides of the branches, 
ovate with a narrow base, wrinkled across, and denticulated at the summit. 
164. S. Loosely branched, cells wrinkled trans- 
versely, crowded, ovate. 
Snail trefoil Coralline, Ellis., Cor. 26. t. xv. f. 23.— S. rug. Linn. Syst. i. 
1308 — Pall. EL 126. — On fuci about low water-mark. 
Height about an inch, irregularly attached to fuci ; the crowded cells give 
the branches a very coarse aspect ; the margins of the orifices are jagged ; 
the vesicles resemble those of the preceding species ; but they are more deep- 
ly wrinkled and notched at the summit. 
165. S. halecina. — Stem compound, pinnated by alternate 
branches ; cells tubular, produced. 
Herring-bone Coralline, Ellis., Cor. 17* t. x. — S. hal. Linn. Syst. i. 1308. 
— Fa//. El. 113. — Thoa hal. Lamour. Cor. Flex. 211.— Common, at- 
tached to oyster shells.
