NOTES ON BRITISH ANTHOZOA. 241 



Phellia murocinda. Two specimens, Warren Point, attached to the 

 under side of stones, top of the Laminarian zone. 



I can now extend the range of this species to four localities : Torquay 

 (Gosse), Thurlestoue, Zennor and Polzeath (these two in Cornwall). 

 This would seem to indicate that the species is not so very rare, but 

 when contracted within its covering it so resembles the many excres- 

 cences or fragments of debris so abundant under all stones in tide pools 

 tliat probably it is often overlooked. A note on the Zennor specimens 

 has already appeared in the Journal (September, 1907). I will only add 

 that the Thurlestone examples agreed with them. The investing " coat " 

 was easily detached, and did not adhere about the base ; after its re- 

 moval the anemones became restless and roamed until they obtained 

 sufficient fragments to form a new covering, when they again became 

 stationary. They only expanded at night, and when contracted and 

 the covering was removed resembled, as Gosse observes, "a young 

 Sagartia viduata." Tentacles 36. The Polzeath specimen was very 

 small and only obtained by chance. Having observed several speci- 

 mens of Mytilus harhatus mingled with M. edidis in a small cave, I 

 detached them and put them in a collecting bottle full of water ; on 

 arriving home I observed the anemone fully expanded upon one of the 

 31. harhcdus, mingled with Sycon coronata, etc. 



V. Hoplangia Durotrix, Gosse. 



Originally mistaken by Gosse for Phyllangia americana, and sub- 

 sequently described in Adinologia Britannica, p. 338, from specimens 

 dredged in Weymouth Bay in 1858, when a colony of "from 50 to 

 100 specimens of this little coral, clustered in groups," was obtained, 

 some of which came into his hands. The animal was not described, 

 being too decomposed. Gosse states, however, that the discoverer spoke 

 of it as resembling Garyophyllia, and " told me that he remarked 

 numerous tentacles, but did not notice whether they were knobbed." 



During a recent visit to Plymouth I examined a colony of more 

 than thirty specimens, chipped off Wembury reef by W. Searle, 2nd 

 September, 1909. The corals were of varying sizes, as Gosse says, 

 " clustered in groups," on the stone. They agreed with the original 

 Weymouth specimens. Diameter of largest unbroken individual, 5 mm. ; 

 height varied up to 10 mm. ; outline varied, some being oval, others 

 nearly circular. The colony had been killed partially expanded, and 

 showed a considerable number of thick, obtuse tentacles, which do not 

 appear to be knobbed. Searle tells me that the animals were colour- 

 less, or at any rate, he did not notice any colours like those of Cnryo- 

 'phyllia.
