A new Fossil Palm from the Cretaceous Formation at Glen Cove, 
Long Island. 
By ARTHUR HOLLICK. 
(PLATE CXLIX.) 
For some years past the writer has been engaged in the study 
of the Cretaceous formation of this vicinity, particularly on Staten 
and Long Islands, and a considerable amount of material repre- 
senting the fossil flora of that formation has been collected. The 
specimens from Staten Island have already been described, * 
—those from Long Island it is hoped to describe in full in the near 
future, but in the meantime it has been thought best to publish in 
advance the accompanying description and plate. 
Probably the greatest surprise experienced in the study of the 
above mentioned material was in the discovery of an undoubted 
palm leaf. The significance of this discovery from the geological 
standpoint need not here receive more than brief mention, as this 
will be fully discussed elsewhere. It is sufficient to say that the 
other fossil leaves associated with it show the geological horizon 
to be the equivalent of the Amboy clays of New Jersey and other 
middle Cretaceous strata in America and Europe, from none of 
which have palms been definitely recorded. In fact the presence 
of palms in lower and middle Cretaceous strata is so rare, if not 
entirely wanting, that this discovery seems to warrant special at- 
tention. They appear in great abundance in upper Cretaceous. 
and Tertiary rocks, and their sudden appearance without any ap- 
parent ancestry has always been a puzzle. The significance of 
the find may therefore be appreciated.
