250 CRETACEOUS LAMELLIBRANCHIA.

figure, is in the Museum of the Geological Society (No. 2197). 
Distribution —Lower Greensand (Perna-bed and Crackers) of Atherfield. 
Hythe Beds of Pulborough.

Remarks.—Some crushed specimens found in the Gault are probably examples 
of P. Fabrina, VOrbigny. They resemble P. Martini, but have coarser and more 
distinctly tuberculate ribs, and the concentric rings appear to be more conspicuous. 
Distribution.—Gault of Black Ven, Okeford Fitzpaine, and Folkestone.
