it Brooklyn and on Lloyd’s Neck, which were recognized by 
Professor Newberry as very similar in aspect to those of the 
-retaceous of New Jersey and the western part of the continent, 
and at a meeting of the New York Lyceum of Natural History, 
on March 23, 1874, he is quoted as saying that the rock in which 
the leaf impressions occur ‘‘is totally unlike anything known in 
this vicinity, and unfortunately has not yet been found in situ. 
But its presence under these circumstances points to its 
existence in place at some locality not far away.” 
Subsequently similar specimens were found in the vicinity of 
Glen Cove on Long Island and at Tottenville on Staten Island, 
in close proximity to the clay exposures, and in 1885 well de- 
ned Cretaceous species were identified from the clay beds at 
Kreischerville, Staten Island 
t was during this period that Professor Newberry began his 
studies of the Amboy Clay flora, by means of which he was 
and thus to settle beyond further question the Cretaceous age of 
the clays on Staten Island and Long Island. 
Immediately after thisa systematic exploration of Long Island 
was begun by the writer, with the result that fossil plants were found 
at a number of different localities, extending all the way along the 
north shore from Brooklyn to Montauk Point. These explora- 
tions were subsequently extended to Block Island and Martha's 
Vineyard and a large amount of additional material was collected, 
all of which was described in ‘‘ The Cretaceous Flora of Southern 
New York and New England”* as a companion volume to Pro- 
fessor es “Flora of the Amboy Clays.” 
imens now on display in the cases mentioned include 
all of ee described by Professor Newberry and about two 
thirds of those described by the writer. The entire series is, 
therefore, especially rich in type and figured specimens; and 
those first discovered possess an historic interest in addition to 
Monographs, U. S. Geol. Survey, vol. 50, 1906.
