A considerable proportion of these fossils belongs to the upper 
solid beds which are in contact, and sometimes alternate, with the base 
of the coralline oolite. It has been remarked above, that the zoological 
characters of those two rocks are much in unison, and there are very 
few species of frequent occurrence in the calcareous grit, which are not 
also discovered in the limestone above. A few fossils, which are not 
among the most common in the calcareous grit, as galerites depressus,
