628 NEW YORK STATE MUSEUM 



Station 9. Schubmehl's quarry 1} miles northeast of Dansville 

 village. About 60 feet of strata, mainly heavy sandstones are ex- 

 posed. Some soft shales at the top contain Manticoceras 



x y and seem to indicate that the sandstones belong to the 

 upper part of the formation. Altitude 1360' to 1420' A. T. This 

 quarry is 18 miles due east of the cliff at Portageville. The only 

 fossils observed were a small Orthis, Cladochonus, crinoid 

 stems and plates, plant remains and F. verticalis. 

 Hydnoceras tuberosum and a few brachiopods occur 

 in a layer of flaggy sandstone that outcrops 1 mile farther north 

 and 325 feet lower. 



Station 10. Exposure along the Pittsburg, Shawmut and 

 Northern railroad between 3 and 4 miles south of station 9, and 



1 mile north of Rogersville station. About 50 feet of heavy 

 sandstones outcrop in this vicinity. No fossils observed here. 



Station 11. In Stony brook and two small lateral ravines about 

 a mile south of the high Stony Brook bridge. Hydnoceras 

 tuberosum occurs in the lower part of the sandstones ex- 

 posed in the main ravine below the highway bridge. 



In the Stony Brook ravine at the high bridge and below to its 

 mouth, about 375 feet of strata are exposed. They show no ap- 

 preciable difference in lithologic character nor in the contained 

 fossils from the same horizon in the river sections. No brachio- 

 pods were observed here but the normal Portage fauna is found 

 in the soft layers. 



Station 12. An exposure of about 50 feet of the sandstones £ 

 mile east of the village of Byersville, in which a thin layer 

 afforded several specimens of Atrypa aspera, a small 

 Orthis, Cladochonus, etc. 



Station 13. The outcrops on Quarry hill, 1 mile south of the 

 village of Nunda. About 35 feet of the sandstones are exposed 

 and a shale bed 6 feet thick of the same character as the one 

 occurring a little below the middle of the sandstones at Port- 

 ageville. A few goniatites and orthoceratites have been found 

 in this shale, and about 25 feet higher a mass of crinoid stems 

 and comminuted shells, in which only a small Chonetes is entire,
