 the lower and middle Atlantic Miocenes respectively, will eventually 

 be found to be equally Avell-marked off in New Jersey, although up 

 to the present time, from the sparseness of the fossil remains that 

 have been collected, no such subdivision could be satisfactorily at- 

 tempted. But from what material we have at hand, it may be 

 safely asserted that the localities which have been so assiduously 

 searched in the neighborhood of Shiloh, and elsewhere in Salem and 

 Cumberland Counties, belong to the older, or 'Marylandian' divis- 

 ion." 



The existence of the newer Miocene dejDosits has now been def- 

 initely determined through the material obtained by Mr. Woolman 

 from the artesian boring at Atlantic City, which has been placed in 

 my hands for examination. The species of fossils obtained here are 

 the following :
