Ostrea cochlear, Poli: living, and moulded on the cable. 
This may possibly be a variety of the polymorphous 
O. edulis, owing its peculiar shape and comparative absence 
of lamination to its remaining attached to corals and other 
cylindrical substances. I think O. rosacea, Deshayes, ought

a brighter colour.
