Sars in Nyt. Mag. f. Naturv., v. vi, p. 140. 
The typical form of the Z. Couchii has not been found on our 
coast, but the curious northern variety, Mammillifera incrustata 
of Norwegian authors, considered by some to be a distinct species, 
has occurred two or three times from deep water, forming a 
continuous crust moulded on shells, the substance of which 
has almost invariably disappeared, shewing an eroding or solvent 
power in the zoophyte. 
This form had long been a puzzle to naturalists before its 
living polype had been discovered. It was before generally 
thought to be a sponge, and was introduced, with doubt, by Dr. 
Johnston into his “ History of British Sponges,” under the 
name of Dysidea? papillosa.

On the under surface of a stone at extreme low water mark, 
near the ‘“ Bear’s Back,” Cullercoats. 
A single group of specimens of this delicate little milk-white 
zoophyte occurred to me in the above locality in the summer of 
1857, since which time I have searched for it several times 
without success. It is very desirable that it should be again 
met with, as the specimens found were in a sickly state, and had 
not the tentacles expanded.

Gosse, Actin. Brit., p. 222, t. viii., f. 5. 
This species was found by Mr. J. Stanger, at Craster, in 
1859 (see Trans. Tynes. Club, v. iv., p. 189). I believe he has 
since found it at Cullercoats, where I have also met with one or 
two specimens.
