The next paper of importance was by Mr. F. W. Harmer,' in which 

 the Lenham beds were regarded as of older age than the Coralline 

 Crag, on account of the more southern facies of the fauna, some of 

 the molluscan species ])eing characteristic of Miocene or Italian 

 Lower Pliocene, which are unknown or rare in the Coralline 

 Crag. The author included a distribution table of shells from the 

 Belgian Diestian beds, showing the Lenham occurrence as well as 

 those found in the " Box-Stones " of Suffolk. Li the following year
