of the department. The fossils from foreign and other American 

 locaHties are too few in numbers of species to represent faunas in 

 the great detail desired for the Museum stratigraphic series, so these

Upper Knobstone shales : 



Soft light gray to green shales with impure fine-grained sand-

 under the New Providence shale below will be found here also 200 



Lower Knobstone (New Providence) shale: 



Blue to green, soft clay shales, with occasional thin ferruginouj 



limestone bands holding numerous fossils 50-ioc 



These limestone beds are often made up of crinoidal 

 remains ; at other times their surfaces are covered with 

 fenestelloid bryozoa. The most common species are : 

 Palceacis cavernosa Miller. 

 Zaphrentis centralis Edwards and Hain-fe. 

 Zaphrcntis cliffordana Edwards and Plaime.
