When first described, the specimens upon which the descriptions were based 

 were thought to represent a palm, and the generic name Serenopsis was given to 

 them. The type figures are reproduced on PL XIII. Specimens subsequently 

 discovered, however, showed beyond doubt that they were not a palm, but a 

 species of Nelumbo, and that the species was similar to, if not identical with, Nelum- 

 bium arcticum Heer, a the figure of which is reproduced on PI. XVI, fig. 7, for 

 comparison. Considerable difference may be noticed between our specimens, but it 

 hardly seems advisable to consider them otherwise than as belonging to a single 

 species. 



The only other representative of the genus which has been recorded from 

 this vicinity is N. primseva Berry, 6 from the Cretaceous clay marl at Cliffwood, 

 N. J., although Mr. Berry has informed me that he has found specimens, which he 

 thinks may be identical with ours, from a lower horizon than that at Cliffwood, 

 near Morgans, N. J.

Family MENISPERMACE^. 



Menispermites Brysoniana Hollick. 



PI. XII, fig. 6. 



Menispermites Brysoniana Hollick, Bull. Torrey Bot. Club, vol. 21, 1894, p. 59, pi. 180, fig. 10; Fifty-fifth 

 Ann. Rept. New York State Mus., 1901 (1903), p. r50. 



The resemblance of this species to Menispermites borealis Heer c is quite 

 apparent , but the imperfect condition of Heer's specimen renders exact comparison
