Parasitical on other Zoophytes, from deep water, Cullercoats

This delicate little Campanularia bears great resemblance. to 
C. Johnstoni, from which it is distinguished by its much smaller 
size, by its cell being much narrower, and not having more than 
half the number of denticles on the margin, and also from the 
pedicles springing from a bulb at the base. It is sometimes 
associated with C. Johnstoni and other closely allied species, 
but may generally be detected at once by its greater minuteness 
and delicacy. Mr. Hincks states that this species is not un- 
common on the Devonshire coast.

A notice of the occurrence of this fine species on the North, 
umberland coast was inserted in the ‘Transactions’ of the 
Tyneside Naturalists’ Field Club (vol. v. p. 60), and some ac- 
count of it was then given. As, however, our specimens differ 
in some respects from the description given by MM. Koren 
and Danielssen in the ‘Fauna Littoralis Norvegie,’ I have 
thought it necessary to describe the British form more at length, 
premising that, as the specimens were obtained from the fisher- 
men in a dried state, the account of them must necessarily be 
somewhat imperfect. 
Polypary about 17 inches long, very slender, linear, with the 
upper part curved into an arch. The lower and sterile portion 
of the stem, occupying from a fourth to a fifth of the entire 
length, is slender and cylindrical above, and scarcely more than 
a tenth of an inch in diameter (when dry) ; about three-quarters 
down, however, it swells abruptly to three times that breadth, 
and is a little flattened, tapering from thence to an obtuse re- 
curved point. About three-fourths of the upper portion of the 
polypary is covered with rather small, sessile polype-cells, which 
are arranged in two very oblique rows in front, sloping upwards 
towards the centre. At first these rows have a central space 
between them, but higher up they approach so close as to touch 
each other. The upper rows contain 5 or 6 cells each, decreas- 
ing in number below. The dorsal ridge is bare, but the polype- 
cells twist once round the axis during their course. The curved 
portion of the stem does not occupy: more than a tenth part of 
the whole length; and at that part the fleshy base of the cells
