CRETACEOUS FORMATION ON STATEN ISLAND. 421 



Heer. This is particularly the case in regard to Figs. 2 and 4, 

 PL XXXI, above quoted. 



Locality : Tottenville, Staten Island. 



10. Hedera sp. ? 

 (Plate XXXVIII, Fig. 5.) 



This specimen is too fragmentary for more than a generic 

 reference. It may possibly be a small specimen of H. prhnor- 

 dialis Sap., as depicted by Newberry in the Flora of the Amboy 

 Clays, PL XXXVII, Figs. 1-7. 



Locality : Tottenville, Staten Island. 



1 1 . Aralia rotundiloba Newb. (?) 

 (Plate XXXVIII, Fig. 2.) 



Aralia rotimdiloba Newb., Fl. Amboy Clays, p. 118, PL 

 XXVIII, Fig. 5 ; PL XXXVI, Fig. 9. 



The obliteration of the lobing in this specimen renders ac- 

 curate determination impossible. It may, perhaps, also be com- 

 pared with Cissites ingens Lesq. (FL Dak. Gr., PL XIX, Figs. 

 2, 2a), or with C. formosus Heer, as identified by Newberry. 

 (FL Amboy Clays, PL XLVII, Figs. 1-8.) 



Locality : Tottenville, Staten Island. 



12. Pistacia Aquehongensis n. sp. 

 (Plate XXXVI, Fig. 5.) 



Leaf entire, linear-elliptical in outline, about ^ in. long by ^ 

 in. wide ; nervation finely and uniformly pinnate, secondaries leav- 

 ing the midrib at a somewhat obtuse angle, closely parallel and con- 

 nected near the margin by cross nervation in a series of angles. 



The specific name refers to " Aquehonga," the Indian name 

 for Staten Island. 



This leaf is closely similar to P. aqttensis Sap. (Ann. Sci. Nat., 

 Ser. V. Bot., Vol. XVIII (1873), p. 105, PL XV, Figs. 1-24), 

 which, however, is a Tertiary species. 



Locality : Tottenville, Staten Island.
