Cells campanulate, border entire; lateral and anterior appendages
canalicular. Branches alternate. Ovicells ---- ?

Habitat: Bass Strait, 45 fathoms dead shells.

There appear to be two varieties of this species, or that different
portions of the same polypidom may assume very different characters. The
larger and probably more common form, is at first sight extremely like P.
catharina, but it will soon be noticed that the branches are alternate
instead of opposite. The shape of the cells and their average size is
precisely the same as in that species. The lateral and anterior
appendages differ in form very considerably. In P. catharina these organs
are longer, more slender, infundibuliform, whilst in P. campanula they
are shorter and thicker and the terminal cup is open on one side or
canalicular. The ovicells might perhaps afford a more striking
characteristic, but they are unfortunately wanting in all the specimens
of P. campanula. The second variety is much slenderer, unbranched, the
cells and their appendages smaller but of the same form, and the cells
usually contain a mass of opaque black matter. This species is parasitic,
and appears to attain a height of several inches.

Fam. 4. CAMPANULARIADAE.

4. CAMPANULARIA, Lamarck.

1. C. volubilis (?) Ellis.

Habitat: Prince of Wales Channel, Torres Strait.

As one or two ovicells, parasitic upon Sertularia pristis, are the only
evidences of this species that have come under observation, some doubt as
to identity of the species with the British form may be entertained.

1. C. dumosa, Pallas.

Habitat: Bass Strait.

Parasitic upon Sertulariae. Rather more slender than the usual British
form, but otherwise identical.

5. LAOMEDEA, Lamouroux.

1. Laomedea torressii, n. sp.

Cells campanulate, nearly sessile upon an incrassated collar projecting
from the stem. Margin of mouth not thickened, with four shallow
excavations.

Habitat: Prince of Wales Channel, Torres Strait.

Of a light brown colour, two or three inches high. At first sight it is
very like Laomedea antipathes, Lamouroux, which occurs in New Zealand,
but differs materially in its smaller size and in the four shallow
emarginations of the mouth, which part in L. antipathes is entire and
with the margin a little thickened.
