These three species of Scalaria, were found in a dis- 
tinct bed of Crag at Ramsholt by the Rev. G. R. 
Leathes ; the S. foliacea, was also found at Woodhall 
in Suffolk, by the same Gentleman. The great resem- 
blance they bear to recent species is remarkable, but is a 
character possessed by many of the Fossils found in the 
Crag ; many also agree with those found in the London 
Clay, amongst them is Sc. semicosta ta,* (M. C. tab. 16 ) 
fragments of which have been met with, accompanying 
the shells before us. 
* Probably Sc. decusstata of Lamarck.
