Report of the State Geologist. 



More recently Professor Prosser lias recorded a fossiliferous locality in 

 the blue-black shales at a cut of the Lehigh and Hudson railroad, one- 

 quarter of a mile southwest of Greycourt station. 



The species found by the writer at the Sugar Loaf locality were : 



Orthis testudinaria. 

 Orthis pectinella. 

 Leptcena sericea. 

 Strophomena alter nata. 

 Crinoid stems. 



A number of specimens of Orthis testudinaria were found in the shales 

 about two miles southwest of Oxford (203), and in the Hudson river sand- 

 stones a mile and one-half northeast of Goshen (472). 



Mr. J. N. Weed, of Newburgh, informs me that fossils are abundant in 

 the sandstones of the point at the south end of Orange lake, and in nearly 

 all the outcrops of the same members north of Middle Hope. 



The fossils found at all these localities indicate a Trenton-Hudson fauna, 

 as previously stated by C. D. Walcott (£. G. S. A., I., 1890, p. 344). 



The Neelytown Limestone. Neelytown is in Hamptonburgh township, 

 four miles south of Montgomery, and in the woods south of Neelytown station 

 is a small area of light blue, granular limestone, which is sometimes brecciated 

 in its upper layers. The limestone first crops out in the cross-road, a few 

 hundred feet east of Neelytown station (477). A short distance to the south, 

 on the west side of the road, in a field, is a small limestone quarry (475). 

 The rock is massive and irregularly bedded, with a brecciated structure, and 

 very indistinct traces of fossils in its upper layers. Chert nodules are very 

 abundant. The strike is east and west, the dip north. There are a number 

 of small outcrops of limestone in the picnic-grove to the southwest, and at 

 the end of .the lane leading into it is a low cliff of the limestone, with the 

 layers dipping gently to the northeast. In texture, the limestone resembles 

 closely the upper layers of Lookout mountain, south of Goshen, and is pro- 

 visionally mapped as of the same age. There is no good evidence that 

 the limestone was brought up by a fault, and it is probably the crest of a low 

 anticlinal fold, from which the overlying slates have been eroded. 



A careful search was made for other outcrops of limestone betw een Neely- 

 town and Walden, but none were found which were clearly in place. 

 Three small outcrops containing Helderberg fossils were found. The first 

 was southwest of Neelytown (405), another east of Montgomery (474), and
