Ostrea plicatula. Ph. — O. cristata. Ph. Whether this is a variety 

 of O. edulis, it is rather difficult to say, as the latter species is subject 

 to great variation. I certainly never met with the common form of 

 our oyster (whether "native," *' Welsh," or '* rock") in the Medi- 

 terranean, nor is it mentioned by Philippi or Payraudeau as a recent 

 species. Tlie kinds now found in that sea are solitary, and not gre- 

 garious. It is well known that the Romans got their principal supply 

 from Britain, although the Circeian oyster ranked as a delicacy with 

 sea-eggs from Misenum and with broad scallops, the boast of 

 luxurious Tarentum.
