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 Greiviopf<is. 

 PopuHle.'i and Plalanus and its nearest allies were seen to be in 

 - the latter. It is 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 j^lace it under 

 that species. No representative of the genus has yet been 

 found in the New Jersey clays, but the presence of P. Newherry- 

 ana, Heer, at Princes Bay, was noted in my previous paper, 

 where it occurred in the same block of stone with Thinnfe/dia 

 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, Aquehonga Manachnong, 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 i^rovisionally 

 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, PI. XXIII. f. 1-6).

 obtained by Mr, Wm. T, Davis from the clays at Kreischerville, 

 the other (f. 3, PI. Ill,) from a concretion found on the shore at 

 Tottenville. •
