This single specimen was found during the excavation of a 
cellar near Richmond Valley station, on the Staten Island 
Railroad, and was obtained from the discoverers by purchase *. 
In its original position it was in a large irregular block or 
fragment of ferruginous sandstone buried in glacial drift. 
It was compared successively with the genus Grewiopsis 
Populites and Platanus and its nearest allies were seen to be in 
the latter. Itis not unlike some of the young unlobed forms of 
P. Haydeni, Newb.; and had it been found in connection with 
Tertiary strata I might have felt inclined to place it under 
that species. No representative of the genus has yet been 
found in the New Jersey clays, but the presence of P. Newberry- 
ana, Heer, at Princes Bay, was noted in my previous paper, 
where it occurred in the same block of stone with Thinnfeldia 
and Liriodendron simplex, Newb., both of which are character- 
istic Cretaceous plants, so that the reference of this specimen 
to a new Cretaceous species does not seem to be unwarranted. 
The specific name adopted is coined from the aboriginal 
name for Staten Island, Aguehonga Manacknong, in order that it 
may always be identified with the locality where it was found.

The two fragments here shown were found by Mr. Wm. T. 
Davis in the Kreischerville clay. Although too imperfect for 
satisfactory determination they have been placed provisionally 
under the above name. It has been found in the clay beds of 
New Jersey, both at Woodbridge and Sayreville, and has been 
described and figured by Dr. Newberry (Flora of the Amboy 
Clays, Pl. XXIII. f. 1-6).
