148 TRANSACTIONS OF THE [JUNE 6, 
This opportunity is taken to put on record a new locality for 
fossils in the Hudson shales (?) of Orange County. While waiting 
for a train at Greycourt some search was made in the exposures of 
blue argillaceous shale along the N. Y., L. E. and W. R. R. for 
fossils, but without success. However, in a cut on the Lehigh and 
Hudson River Railroad, about one-fourth mile southwest of the 
station, a slightly calcareous layer was found in which fossils were 
not uncommon. They are more or less distorted by pressure, but 
the locality is favorable for excavating in search of specimens. 
It appears that fossils have been found at only a few places in 
the Hudson stage of Orange County. Mather mentions two locali- 
ties at which ‘‘a few specimens of testacea”’ were found ‘near the 
villages of Walden and Sugarloaf in Orange County.’ Sugarloaf 
is four miles southwest of Greycourt, on the Lehigh and Hudson 
River Railway, and Walden is in the northern part of the county. 
Fossils were collected at these localities by Mr. Nelson H. Darton, 
in 1885, and he added a third locality, Rock Tavern, ten miles west 
of Newburgh, and intermediate between the other two places. Mr. 
Darton enumerates eight species from near Sugarloaf village, two 
from Rock Tavern, and four from near Walden.” 
These localities are also mentioned by Mr Darton in a letter 
entitled ‘“‘The Taconic Controversy in a Nutshell,” published Janu- 
ary 22, 1886.* The fossils contained in these slates Mr. Darton 
was inclined to consider as of Trenton age.‘ 
Professor Cook stated: ‘“‘No fossils have been found in the rock 
[ Hudson River slate] in this state [New Jersey ], though they are 
abundant in it in some parts of New York ’”® 
Mr. Charles D. Walcott, in a paper on “The Value of the term 
‘Hudson River Group’ in Geologic Nomenclature,’ states, under 
the heading of ‘‘ Discoveries of Recent Years,” that ‘‘ the discovery 
of fossils other than graptolites in the dark shales or sandstones of 
the Hudson River. group below Albany has been infrequent. Mr. 
T. Nelson Dale found a few species at Marlborough, about eight 
miles south of Poughkeepsie, in 1879, and Mr. Nelson H. Darton 
found a few Trenton-Hudson species twenty-one miles south of 
Newburgh [Sugarloaf village], in 1885. On the east side of the 
Hudson, Mr. Dale discovered, in an argillaceous schist near Vassar

Oxford limestone to the Blue, or Shawangunk Mountain. at Otisville there is 
a rolling country underlaid by slates, which have been recently found to be 
Trenton in age ;’’ also p. 134, f. n. 142, on Craigville, two miles northeast of 
Greycourt, see the statement that ‘‘This series of slates, occupying large 
areas in Orange County, New York, and extending southward into New Jer- 
sey, contains a mixed Hudson River and Trenton limestone fauna, and should 
perhaps be designated Trenton.”’
