Two specimens of this species were found by Mr. 
Herbert C. Chadwick opposite the ferry-slip, at Bangor, 
in August, 1887, attached to the rock. I was unable to 
record it in my former Report, as I heard only quite 
recently about this find. The one specimen is about 3 
cm. in height, the other one 1°33 cm. ‘This species has 
been recorded by Bowerbank from the coast of Scotland ; 
coast of Northumberland; Island of Harris; Hebrides ; 
and from Gilter Sound, near Tenby. I may mention that 
about fifteen fine specimens of Suberites ficus were dredged 
by Professor Herdman in the Sound of Mull, in 1881, and 
are now in the Zoological Museum of University College, 
Liverpool.

Mr. Higein, in his ‘“‘ Report on the Porifera of the 
L.M.B.C. District,” page 85, has already mentioned that 
in our district both forms of Cliona celata are found, the 
‘massive’? and the “‘ sinuous”’ one, but I am not aware 
that massive specimens of such a size were ever found before 
in our neighbourhood as those which were dredged on tke
