Two specimens of this species were found by Mr. 

 Herbert C. Chad wick opposite the ferry-shp, 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"3 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 S^iher lies 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. Higgin, 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 the 

 " Hyaena" expedition of May 25th, 1890, on the west coast
