9 Manlius limestone. This formation which is nearly 35 feet 

 thick carries a typical Manlius limestone fauna. The fossils in 

 some cases are not well preserved. This is specially true of 

 Tentaculites gyracanthus Eaton, of which well pre- 

 served specimens are rare. From the Nearpass section, however, 

 on the reverse side of a thin slab collected for specimens of 

 Megambonia aviculoidea Hall, there was found 

 Tentaculites gyracanthus equally as abundant as in 

 the sections farther north in New York State. They are how- 

 ever in a very poor state of preservation and may readily be 

 passed unnoticed. 



ORANGE COUNTY SECTIONS 



In the section a short distance southeast of Port Jervis at 

 Carpenters Point neither the Cobleskill nor the Decker Ferry 

 formations can be observed, though several members of the Hel- 

 derbergian are shown at this locality. About 2 miles farther north 

 from Carpenters Point the Erie Railroad crosses these formations 

 1>ut they are all too deeply covered to show any outcrops. 



The best place in Orange county for the examination of the 

 Cobleskill and Decker Ferry formations is in the valley of the 

 Neversink about 8 miles north of Port Jervis and i mile east of 

 'Cuddebackville. Here there are a number of parallel ridges 

 which include not only the Cobleskill and Decker Ferry forma- 

 tions, but the Rondout and Manlius together with the Helder- 

 bergian members of the Devonic. 



About I mile southeast from Cuddebackville there is an old 

 quarry with a limekiln near by. The beds here are nearly ver- 

 tical, and just to the east of the quarry the Cobleskill together 

 with the upper part of the Decker Ferry formation is shown. 

 The rock is here much sheared and is traversed by mineral 

 veins. This outcrop of the Cobleskill and others in the vicinity 

 of the same horizon are noted by Ries^ and are included by him 

 with the Tentaculite (Manlius) limestone. The lower part of 

 this outcrop is not favorable for collecting but in the upper part
