race, extending northward from the terminal moraine to the shores 
of Long Island Sound and its harbors. A description of the geology 
of this area, including a discussion of the exact geologic age of the 
Manhasset gravels, and excellent views of sections of the pit 
above mentioned, may be found in a paper by J. B. Woodworth,* 
to which the writer would respectfully refer those who may be inter- 
ested in the Pleistocene geology of the locality. 
The specimens described were all obtained from the ferruginous 
shale and sandstone constituents of the gravel, representing 
fragments and masses of Cretaceous clay and sand which were 
eroded from the parent beds, hardened by oxidation of the in- 
cluded iron, and ultimately worn into the rounded cobblestones 
and boulders of the Manhasset deposits. The largest Cretaceous 
fossiliferous boulder thus far brought to light anywhere on Long 
Island was found in this pit. It was about two cubic feet in mass, 
and on one of its exposed surfaces were quantities of beautifully 
preserved leaf impressions. This surface was separated from the 
main mass and is now in the paleobotanical collection of the 
Garden. A photograph of a portion of itis represented by Plate 162. 
The writer gratefully acknowledges his indebtedness to Mr. 
George R. King for courtesies extended, and for facilities placed 
at his disposal, while engaged in collecting at and in the vicinity 
of the gravel pit. Also to Mr. Howard J. Shannon, of Jamaica, 
N. Y., for freely placing at his disposal specimens personally 
collected at the Glen Cove locality. The writer also enjoyed the 
pleasure and benefit of the companionship of Mr. Edward W. 
Berry and Mr. Arthur B. Bibbins, of the Maryland Geological 
Survey, and Professor Edward C. Jeffrey, of Harvard University, 
during part of the time spent in the field. 
Ail of the specimens described in this paper are included in the 
paleobotanical collections of the New York Botanical Garden.
