FOSSIL MOLLUSC A. 259 



Mr. Robert Damon's excellent book on the geology 

 of the latter coast supplies the tourist with more 

 good fossiliferous localities than he will have time 

 to visit, unless he has got nothing else to do, and 

 both time and means to indulge his fossil-hunting 

 propensities. Of course, all the strata at Kimmeridge

 with another fossil bivalve, Exogyra bruntrutana. 



Between Swanage and Bridport the geologist 

 gradually passes from the Eocene, through the Cre- 

 taceous, down to the lower strata of the Oolite. The
