 A HISTORY OF CORNWALL ZOANTHARIA The Zoantharia, which include the sea anemones and corals, were made a subject of special study by Dr. Cocks at Falmouth, who not only gave a list of local species in his 'Fauna of Falmouth' in 1849, but published a descriptive account of all the county species he had examined, with plates, in the Ann. Rep. Roy. Cornw. Polyt. Sac. (1852). Mrs. Gough, of Penzance, devoted a considerable amount of attention to the sea anemones of Mount's Bay, and embodied her observations in a paper in the Trans. Penz. Nat. Hist, and Antiq. Sec. (new ser.), ii. (1885-8). 1. Actinoloba diantbus, Ellis (MetriJium senilis, L.). F. c. along S. coast from Whitsand B. to Sennen within l.w-m. on sheltered shelving rocks, in tidal caves, and occ. to 25 fm. ; St. Ives, Newquay, Boscastle, rock-pools of Annett, and from 40 fm. off Menavawr, Scilly! 2. Sagartia bellis, E. & S. (Cereus pedunculatus, Pennant). Locally c. all round the coast and at Scilly on indented and fissured rocks, in rock- pools and in crevices in muddy nooks. Of Gosse's vars., tyriensis, versicokr, modesta and sordida all occur about Mount's B. Cocks's S. Johnstoni from Gyllyngvase is probably a variety of this species 3. S. miniata, Gosse.

S. parasitica, Couch (Adamsia polypus, Forskal). Apparently n. unc. at 5 to 30 fm. gen. associated with Eupagurus bernhardus, but occ. found on Pinna ingens, Cyprina islandica, and on the claw of the Corwich crab, Maia squinado (Couch) ; 14. c. Plymouth, Fowey, Mevagissey, Gorran Haven, Falmouth, Helford, Penzance, St. Ives, Newquay, and at Scilly ! S. chrysosplcnium, Cocks. Scarce but occ. found under surfaces of stones at extreme l.w. and in rock-pools at Gyllyngvase, Pennance, Helford and St. Ives (Cocks) ; Laregan Rocks, Mount's B. (Mrs. Gough) Described by W. P.

Abund. in bright shallow pools between t-m. all along the S. and locally on the N. coast ; Annett, Tresco, and St. Mary's, Scilly, c. ! vars. smaragdina, rustica, sulphurea, and alabastrina occur in Mount's B. (Mrs. Gough) Actinia mesembryanthemum, E. & S. (Actinia Eques, Linn.). Most abund. along S. and locally on N. coast, and at Scilly on rocks and stones between t-m.
