1018 NEW YORK* STATE MUSEUM 



The only fossils found were a few brachiopods scattered 

 through the shale and several impressions of Liorhynchus on 

 the lower surface of a sandy layer. 



On the east side of the valley of Oazenovia creek, V/ 2 miles 

 north of Holland, the sandstones of the Portageville horizon 

 are exposed in an old quarry and other places near the rail- 

 road, and the black shales that succeed them may be seen in 

 the bed of the stream in the village. 



In a small ravine on the east side of the valley a little north 

 of the railroad station, there is an exposure that begins about 

 50 feet above the sandstones, in which there occurs, 100 feet 

 above the bottom, a layer of calcareous sandstone a foot or 

 more thick, of the same character as the one in this horizon 

 in the Java Village ravine, except that no fossils were found 

 in it. A loose slab, fallen apparently from but a few feet 

 higher, contained Liorhynchus, Ambocoelia umbonata 

 and Orbiculoidea.
