Parasitical on other Zoophytes from deep water, Culler- 
coats, occasionally. 
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. Johnston 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 uncom- 
mon on the Devonshire coast.

This species, which I described under the name of C. gracillima, 
is apparently the same as the C. fruticosa of Sars, previously 
published in a Norwegian periodical, which I had not until lately 
the opportunity of seeing.

I adopt the opinion of M, Sars, lately communicated to me by 
letter, that this species, which we had each described by a 
different name, must be referred to the G. robusta of Stimpson.
