304 PLIOCENE MOLLUSCA. 



deflexed anteriorly ; aperture broadly lunate, margins distant ; outer lip narrowly 

 expanded, having a slight thickening within ; columella margin deflected, with 

 a reflected callus concealing the umbilicus. (K. and B.B.W.) 



Dimensions. — Diam. (max.) lO'-A mm. H. 10 - 8 mm. Mouth 6-7 x 8*8 mm. 



Distribution. — Not known living. 



Fossil : Coralline Crag : Ramsholt. 



Remarks. — The specimen now figured was found by Mr. Ogden, jun., in the 

 Crag at Ramsholt, exposed in a low cliff on the banks of the River Deben. It 

 has been determined as new, and very appropriately named after the discoverer 

 by Messrs. Kennard and B. B. Woodward. They state that they have failed to 

 identify it with any Continental species, either living or fossil, its nearest living 

 ally being the southern shell Helix (Macularia) Oberndoerferi, Kobelt. I trust 

 they will pardon my suggesting the possibility of the bed at Ramsholt from which 

 this fossil was obtained being of Coralline rather than of Red Crag age, as they 

 suggest. 



H. and A. Adams state that all the known species of Macularia are from the 

 south of Europe.
