Pliocene : Biot, Bologna, Orciano, Livorno, Caltabiano, Messina. 



Pleistocene : Monte Pellegrino, Ficarazzi, Glravina, Livorno, Valle Biaia, Naso, 

 Messina. 



llemarhs. — This small shell, known to Wood from two localities only, has since 

 been found not only in the Coralline, but, though rarely, at all horizons in the Red 

 Crag from Walton to Butley, an^ fide R. AVigham, in the Icenian of the Norwich 

 district. It is a southern and Miocene form with a wide range in the Pliocene and 

 Pleistocene of the Mediterranean region. Prof. Sacco figures 8 or 9 different 

 varieties of it.
