Hampshire and Western Sussex. 



The south-western portion of the Wealden denudation has been so fully 

 described by Mr. Murchison and Mr. Martin, that I shall refer to their publi- 

 cations already quoted, for an account of it; giving* here only some additional 

 facts with which I have been favoured by those two gentlemen : and for a 

 similar reason I shall leave untouched the territory of Mr. Mantell in Western 

 Sussex. 



(69.) Hampshire. — Accumulations of broken chalk flints have been found 

 very extensively^over the surface of the Lower green-sand, on thenewroad from 

 Petersfield to Midhurst in West Sussex ; at Sheet Hill ; and several other places 

 in this part of Hampshire. In the former situation, which is about three miles 

 from the nearest chalk, the detritus covers an uneven surface of the sand, 

 which appears to have been acted upon precisely in the same manner as that 



* In the list of the fossils of the vicinity of Folkstone (p. 131.), this shell has been called a 

 Trochus : but a very fine specimen obtained from Kent, and kindly mentioned to me by Mr. Charles 

 Manning, has since convinced Mr. Sowerby that the true genus is Pleurotomaria. See the de- 

 scriptions of the new species, in the Appendix.
