comparing i, 2 and 3 it should be noted that the distance between 

 Becraft and Rondout is not nearly so great as it is between Rondout 

 and Fort Jervis. 

 Manlius 55 feet 



Three Stromatopora beds occur, o, 2 and 12 feet respectively be- 

 low the top of the Manlius. Besides the Stromatopora, the most 

 characteristic fossils are Spirifer vanuxemi, S. coral- 

 linensis, S. eriensis var., Whitfieldella cL 

 n i t i d a , etc. 

 Coeymans 45 feet 



Layers of chert are not infrequent in this limestone, an argil- 

 laceous calcarenite.^ The lowest bed of this, resting immediately 

 on the uppermost Stromatopora bed, contains some specimens of 

 Favosites helderbergiae and many of G y p i d u 1 a 

 g a 1 e a t a . In the Coeymans were also found D e 1 1 h y r i s 

 perlamellosa, Spirifer cyclopterus, S. ma- 

 cro pleura (one specimen) , Leptaena rhomboid a lis, 

 Pterinea? textilis (one specimen) , etc. 

 New Scotland 68 feet 



Thin bedded, argillaceous to silicious rocks with a variable 

 amount of lime carbonate present. Orthothetes wool- 

 Vv^orthanus, Stropheodonta becki, Spirifer 

 macropleura, Delthyris perlamellosa, Eatonia 

 peculiaris, E. medialis, D i a p h o r o s t o m a v e n - 

 t r i c o s u m , etc. 

 Becraft 40-45 feet 



Coarsely crystalline limestone (calcarenite). The most abundant 

 and characteristic species are Spirifer concinnus, Gypi- 

 dula galeata (usually small) , Atrypa reticularis 

 and Uncinulus campbellanus. 

 Port Ewen 25 feet 



A dark crystalline limestone, very similar to the Coeymans. 

 Monotrypella tabu lata specially characterizes this hori- 

 zon ; this is, however, also found in the Coeymans. Other fossils 

 are Spirifer concinnus, S. cyclopterus, Del-
