130 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Mar. 23, 



of 4 species of Fish, a Crab, 163 species of Mollusca, an Echinoderm, 

 and 1 species of Corals, the greater part in a fine state of preser- 

 vation. The Corals have been examined by Mr. Lonsdale, who, in 

 spite of delicate health and the many demands upon his time, is 

 always ready to lay the stores of his information at the disposal of 

 this Society. His report accompanies Col. Heneken's Memoir. 



Sir Philip Egerton was so obliging as to examine the Fish teeth, 

 and he identifies them with the following species : — 



Carcharodon megalodoii. Hemipristis serra. 



Oxyrhina xiphodon. Odontaspis dubius. 



The Carcharodon and the Hemipristis are quoted by American 

 geologists as occurring in the Eocene formations of South Carolina, 

 Georgia, and Maryland ; and also in the Miocene formations of 

 Maryland and Virginia. They are all four found in the Malta beds. 

 Of these, 14 are beheved to be recent, or less than 9 per cent. In 

 the former list, 1 3 recent shells were enumerated ; but from this 

 number 3 are to be deducted, which had been erroneously attributed to 

 this formation, as before mentioned. Two others, which were looked 

 upon by Mr. Sowerby as varieties of the Phos Veraguensis and Can- 

 cellaria reticulata, are not considered identical with those shells by 

 the naturalists who have had more perfect specimens to judge from, 

 and are therefore also deducted. There remain 8, to which 6 more 

 are to be added from the collection now sent. The following is the 

 list : — Habitat. Fossil in 



Triton variegatus W. Indies. 



femoralis do. 



cr t / Philippines and 



* \ West Australia. 



Turbinellus ovoideus. . . . W. Indies. 



infundibulum .... do. American Miocene. 



Terebra flammea do. 



Oliva hispidula do. 



Pleurotoma virgo ? 



Nassa incrassata Mediterranean. Bordeaux, Dax. 



Natica sulcata W. Indies. 



Bulla striata do. Montpellier. 



Chama arcinella do. American Miocene. 



Venus puerpera Indian Seas. 



■ Paphia W. Indies. Vienna. 



It was mentioned in the report of 1850, that Mr. Sowerby, who 

 examined the Mollusca, was much struck by the close resemblance 

 which many bore to shells now living in the China Seas and the 

 Pacific. That resemblance is maintained in the collection lately re- 

 ceived. After a close comparison with the shells of the British Mu- 

 seum, Mr. Cuming's, and other private collections, in which I was 

 kindly assisted by Mr. Searles Wood, Dr. Baird, and Mr. Cuming, in 

 many cases the nearest analogue was from those seas. In addition 

 to the cases mentioned by Mr. Sowerby, the following may be enume- 

 rated: — 



Cassis, scarcely distinguishable from C. abbreviata, Acapulco.
