The nomenclature of the Fibrous Sponges adopted in this 
article is that of Professor Oscar Schmidt, as given in his 
“Grundziige einer Spongien-Fauna des Atlantischen Gebietes,” 
Leipzig, 1870. A number of the specimens we have found 
in the Forth are not yet identified.

Frequent on roots of Laminaria, in the 
lower littoral zone, at North Berwick, etc.
