farcta, F. & M. sp., having PL nitida, D'Orb., between it and 

 the type ; whilst PL vulgaris, D'Orb., stands next beyond it in 

 divergence from PL farcta. Ann. N. H. ser. 3. v. p. 178.

 Adriatic Sea ; and fossil in the Tertiary beds of Paris, Bordeaux, 

 and Castel-Arquato. A well-developed form of P. lactea. Walker
