Ostrea cochlear, Poli : living, and moulded on the cable. 

 This may possibly be a variety of the polymorphous 

 0. epulis, owing its peculiar sha])C and comparative absence 

 of lamination to its remaining attaclied to corals and other 

 cylindrical substances. I think 0. rosacea, Deshayes, ought 

 to be united with 0. cochlear, as it differs only in having 

 a brighter colour.
