* Lignite and imperfect traces of carbonized vegetables. '' Forms beds of limestone. 

 ■^ Constitutes the principal portion of the argillaceous beds in some localities. 



"^ This species resembles C. corneus of Lamarck, vol. vi. Entire beds of limestone are formed of it, associated with 

 shells of the genus Unio. It occurs also in vast quantities in the grit. 



* Two or more species in limestone with Cyclades. ^ In limestone. ^ In limestone and shale. 

 •* Scales detached, small vertebrae, very imperfect remains in shale. ' Vertebrffi ; uncertain if from grit or shale. 

 '' VertebrjE from the clay between the limestone, on the authority of Dr. Fitton. 



%• This Catalogue was begun at the suggestion of Dr. Fitton, and intended as a supplement to his Memoir on the 

 South-east of England, read before the Geological Society on the 15th of June 1827, and about to be published in a 

 subsequent part of these Transactions. A paper by Dr. Fitton, first establishing the subdivision of the green and ferru- 

 ginous sands, appeared in the Annals of Philosophy for November 1824. 



Results, 



There have been discovered in the strata of Sussex (exclusively of the organic contents of the comparatively modem 

 alluvial deposits) the fossilized remains of nearly four hundred species of animals and vegetables, of which the following 

 arrangement exhibits a condensed view.

The geological distribution of the species above enumerated is shown in the following Table, and the zoological cha- 

 racters of the respective formations are thus established, so far as the present imperfect state of our knowledge will permit. 



t Under this term the ancient multilocular genera are included. See Fleming Brit. Anim. 226.
