Suborder CAMPANULARIDA. 
Family Campanularide. 
Genus CAMPANULARIA. 
a. With free gonozooids, of the Obelia type. 
C. flabellata, n. sp. 
peaetnen cist ae gelatinosa, Van Beneden, ‘ Les Campanulaires,’ 33, 
pl. Ze 
Hydrocaulus filiform, somewhat zigzag, branched, strongly 
annulated above the origin of the branches, of a dark horn- 
colour; branches given off at each bend of the stem, alternate, 
flexuous, rather short and fan-shaped, divided and subdivided 
dichotomously, and ringed above each division, forked imme- 
diately above the point of origin, the arms of the fork tending 
in opposite directions, and giving a subverticillate appearance 
to the ramification. Hydrothece alternate, short and subtri- 
angular, with a wide aperture and an entire margin, borne on 
ringed and tapering pedicels of variable length. Gonothece 
axillary, ovate, pedicellate, slightly flattened at the top, with a 
short tubular orifice. The gonozooids are probably, like those of 
C. geniculata and dichotoma, of the Obelia type. 
This species seems to have passed as a variety of C. dichotoma. 
It is, however, separated from it by a group of distinctive cha- 
racters—the subverticillate habit, the flabelliform branches, the 
flexuous stem, the short subtriangular calycle, and the much 
larger size. C. flabellata attains a height of 8 or 10 inches. 
Hab. Tenby, on rocks in tide-pools (Alder) ; Scotland (Sir J. 
Dalyell). 
* Gonozooids unknown. 
C. gigantea, n. sp. 
Stem delicate, of a very light horn-colour and papyraceous 
texture, annulated at the base and below the calycle, irregularly 
and sparingly branched; branches erect, copies of the primary 
shoot, sometimes themselves branched. Hydrothece of enor- 
mous size, deeply campanulate, very wide at the top and for 
some way below it, and then tapering off gradually; length 
about double the greatest width, the rim cut into numerous 
broad and blunt teeth. Gonothece unknown. 
Height about an inch. 
The calycles of this well-marked form are many times as large 
as those of any other British species.
