The rock from whence the majority of specimens were obtained 

 was a soft pisolite, the shells being generally well preserved and 

 rarely broken. Associated with them were rolled fragments of marly 

 rock and casts of shells in a similar matrix (chiefly Nerincea and Ce- 

 rithid), much rolled and eroded, some of them being slightly incrusted 

 with calcareous matter, apparently resembling a similar phsenomenon 

 of recent origin described by MM. Serres and Figuieras occurring in 

 the Mediterranean, in the vicinity of Algiers. 



The oolite rock dips towards the adjacent valley, and has been 

 pierced about 60 feet in sinking a well close to the line of railway : it 

 is also quarried in the vicinity. 



t These species arc described in the Appendix to tliis paper, and figured in 

 Plate XIV.
