This is the more notice-. Fig. 6 Diagram of section F able since the lower part of F3 and the upper part of F2d have the same lithic characters and often weather as a single bed. F3 An alternation of coarsely and finely crystalline limestone. Coeymans 1-7 inches The followinsf is a list of the fossils found here: 6 Favosites helderbergiae Hall C 12 Lichenalia torta Hall c 22, Atrypa reticularis {Linnaeus) r 45 Gypidula galeata (Dalman) c 89 Stropheodonta varistriata (Con- rad) 90 S. varistriata var. arata Hall 94 Strophonella punctulifera (Con- rad) 102 Uncinulus sp. This bed is subdivided as follows: F3a A coarsely grained limestone mostly composed of crinoid joints, which seems to be a modified continuation of F2d. A few brachiopods w^ere noticed 1-3 inches F3b This is of the same lithic character as F4 and doubtless rep- resents the beginning of the latter bed, but the conditions changing brought the typical F3 sediment in again, for at the northern end of the quarry, F4 rests on F3a but as we follow F4 southward, we find it penetrated by a more coarsely grained layer which at the southern end of the quarr\^ attains a thickness of 3 inches. This is represented in the preceding figure [] 1-3 inches. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration a
