List of Fossils of the Gault and Green-sands, in the interior of Kent, 



and part of Surrey. 



Ammonites dentatus. Gault. Brick-field near Westerham. F. 



A lautus. Gault. Same place. F.

A ? A fragment of a very large Ammonite (or Hamite ?), was found by one 



of my sons (W. I. F.), among the lowest beds of the green-sand on the south 

 of Brasted in Kent; which, when complete, must have formed a spiral between 

 two and three feet in diameter. The separate convolutions are about nine inches 

 in breadth ; and the flutings of the surface, which are simple, are about two 

 inches across the broadest part, and in depth about an inch. The specimen be- 

 longs, not improbably, to one of the large species which occur in the Gault 

 of Yorkshire, (see Phillips).
