INTRODUCTION 
Three previous papers, dealing directly or indirectly with the 
Cretaceous flora of Long Island, were published by the writer,* 
all of which, together with a number of contributions to the Cre- 
taceous flora of the adjacent islands, were subsequently revised and 
were included in and issued in the form of a single quarto volume.t 
In this monograph the general stratigraphic relations of the insular 
plant-bearing horizons may be found fully described and discussed 
and, as no additional information in relation to the subject has 
since been acquired, any extended remarks in such connection 
in this paper do not seem to be necessary. 
Subsequent to the time when the above-mentioned monograph 
went to press, however, a considerable amount of new paleo- 
botanical material was collected from Staten Island, Martha’s Vine- 
yard and Long Island, which latter it is the object of the present 
paper to describe. Some of the specimens were obtained from the 
clay outcrop in the beach a short distance west of the Glen Cove 
steamboat dock, where the bulk of the previous collections were 
made; but the larger part was found on the east side of Nlanhasset 
Neck, in the vicinity of Roslyn, in J. B. King & Co.’s gravel pit—a 
locality not before examined for fossil plants. 
This pit is excavated in the Manhasset gravels, which constitute 
the major formation of the deeply dissected, early Pleistocene ter-
