FAUNA OF THE TINTON BEDS. 



The most complete fauna of the Tinton beds has been col- 

 lected from the exposures in the deep cut at Beers' Hill, where 

 fossils have been secured from several distinct beds. The as-

 and in the number of localities reco'gnized each of these beds is 

 considered separately. The various localities from which fossils 

 have been studied, with the several local faunas, are as follows :

 which has furnished the most abundant fauna, is in the deep
