PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [May 16, 



ficial or vegetable soil, have a more recent aspect than others which 

 are found in a light-coloured sand : none of them were referable to 

 the fossil corals of America known to Mr. Lonsdale. 



The Echinoderm is a scutella closely alhed to, if not identical with, 

 a recent species. 



Mr. Morris, who kindly examined the Foraminifera, informs me 

 that four are identical with the following known species : — 



Nodosaria raphanistrum . . . Fossil at Malta, &c. 



affinis Fossil at Vienna. 



Robiilina cultrata Recent, and fossil at Vienna, Sienna, &c. 



Rosalina Beccarii . . . , Recent, and fossil at Bordeaux. 



Others belong to the genera Textularia, Beiitalina, &c. 



The Mollusca were compared by Mr. G. B. Sowerby and myself 

 with such recent and tertiary shells as we could get access to, more 

 especially with the rich collection of American tertiary shells in the 

 possession of Sir Charles Lyell, who most kindly permitted us to con- 

 sult his museum. The result was as follows. Omitting such as are 

 too imperfect for specific determination, the shells are referable to 77 

 species, belonging to the following genera : —

 doubt. The following is the list : —
