Fy This stratum is characterized by many chert bands which 

 vary in width from a mere Hne to 2 inches 26 feet 



This is subdivided as follows : 



F/a A very dark blue limestone with a few bands of chert. Fos- 

 sils were not abundant. The only species found were E n t e r o - 

 las ma strictum Hall c and Gypidula galeata (Dal- 

 man) c. Coeymans 5 feet 4 inches 



F7b Blue shaly limestone weathering to a very light chocolate 

 color. Coevmans I foot 



5 Enterolasma strictum Hall c 

 45 Gypidnla galeata (Dalman) c 



47 Leptaena rhomboidalis {Wilck- 

 ens) c 



F7C A^ery dense, dark blue limestone with very many chert bands 

 which, when weathered, furnish excellent bryozoa. The chert of the 

 preceding beds even when weathered shows little else than crinoid 

 joints and comparatively few of these. Coeymans. . 4 feet 4 inches 



The following fossils were collected here, most of them from the 

 weathered surfaces of the chert bands :
