thing to Mr. Macgillivray’s good description. 
3. CAMPANULARIA INTERTEXTA, [. Q. Couch. 
Hab. Parasitical on Sertularine. 
This is described by Mr. Couch as differing greatly from 
the kindred species, and as being lke a loose-textured 
sponge, having minute campanulate cells, with even, trun- 
cated apertures. Dr. Johnston speaks doubtfully respect- 
ing it. 
4. CAMPANULARIA SYRINGA, Creeping Bell Coralline, 
Hillis. (Plate XI. fig. 37.) 
Hab. Parasitical on other corallines, and the lesser fuci. 
After describing C. volubilis, Ellis says there is another 
species of this creeping kind of bell coralline, which is found 
adhering to the sea-fir coralline. The difference between 
them is, that the twisted stalks of this are much shorter, 
and the cups are longer-shaped, and not indented about the
