Identity of Fossils of the Great Oolite of Stamford with those of the 

 Great Oolite of Northampton. 

 As, I shall not again refer in detail to the beds of the Great 

 Oolite, I will here point to the identity of the organic forms which 

 are most abundant or most significant in the beds of that formation 

 in the Northampton district, with those of the greatest frequency or 

 of equal significance in the beds which I have termed " Great 

 Oolite " in the Stamford district ; by which identity, as I think, the 

 equivalency of these beds in the two localities is palseontologically 

 established. 



The most prominent fossil probably in the Great Oolite Lime- 

 stone of Northampton is the large Nautilus Baheri ; of which nume- 

 rous examples have been found in the limestone of Belmisthorpe, 



* The fossils in the Upper Estuarine Clays are for the most part very imper- 

 fectly preserved ; and it must be understood, therefore, that the fossils in the 

 list marked with a note of interrogation are only probably identified.
