In the Report of the Cornwall Polytechnic Society for 1851 Mr. W. P. Cocks described a species of sea-anemone under the name of Actinia tuberculata. He gave a small figure in illustration, but this was somewhat indefinite. His description is as follows:—“ Body globular, light brown, densely covered with large greyish-white tubercles, the apex of each tubercle depressed; disc white; mouth large, lips thick, corrugated, and everted; tentacula numerous, large, obtuse, some bifurcated, others trifurcated. Diameter three and a half inches when contracted.”
