of the margin of the polype-cell. When folded down or 
drawn within the cell, the top of this appears truncated. 
5. CAMPANULARIA LACERATA, Dr. Johnston. 
Hab. Parasitical on Plumularia falcata, Berwick Bay, 
Dr. Johnston; and on Cedlularia scruposa, at St. Andrew’s, 
Prof. J. Reid. 
This little creeping bell coralline seems as yet seldom to 
have been met with. It is described by Dr. Johnston, 
“Cells arising from a slender tubular stem, which creeps 
upon the ramifications of other corallines, scattered, on 
very short pedicles, consisting of four or five equal rings, 
ovate, the upper part of a conical form, and divided into 
six deep lanceolate segments, which, in our specimens, are 
all connivent, and form an acute apex.” Professor Reid 
states that the tentacula can extend twice the length of the 
cell, and that they have numerous small tubercles adhering 
to their outer surface. 
** Stem composed of many parallel tubes. 
6. CAMPANULARIA VERTICILLATA, Horse-tail Coralline, 
Hilts. (Plate X. fig. 33%.) 
Hab. Near Whitehaven, Dr. Brownrigg; near Hartle- 
pool, Mr. Hogg; Scarborough, Mr. Bean; Cullercoats, 
* Tn the Plate this is named, by mistake, Laomedea verticillata.
