Notes on the Geology of 



193 



for pointing out discrepancies which hitherto had. escaped obser- 

 vation, but which the microscopic eye of the "Neufchatellian 

 Naturalist" at once discovered. The splendid Mellita, the admi- 

 ration of all who have seen it, resembles in its external form the 

 recent Mellita (Scutella, Lam.) quinquefora of the coast, and has 

 always been considered identical. The latter has never been 

 found over five, or perhaps four and a half inches in diameter. I 

 have never seen one so large ; they seldom exceed three and a 

 half inches on this coast; whereas this fossil will average eight 

 inches. Many are found of nine, but not one less than five 

 inches in diameter, and of this last size few are to be had. At the 

 suggestion of Prof. Agassiz, I will call it Mellita ampla, it being 

 the largest known of any species in the world, and shall describe 

 it, with its characteristic differences, in the Journal of the Acad- 

 emy of Natural Sciences, of Philadelphia, together with ether 

 new shells from the beds of the Charleston basin. 



The following catalogue contains one hundred and forty-seven 

 species of Post-pliocene fossils now in my collection, and that of 

 my friend, Dr. Thos. L. Burden. They were all of them obtain- 

 ed from the exposures of Yonge's Island ; Abbapoola creek and 

 Ratlin's bridge, John's Island ; Submarine bed, Stono river ; John 

 Hamblin's, Esq., Christ Church Parish; and at the plantations of 

 A. H. Brown. Esq., Old Town Creek, and Joseph F. Bee, Esq., 

 Ashley Ferry, St. Andrew's Parish.
