Celastrus arctica Heer, Fl. Foss. Arct., vol. 7, 1883, p. 40, pi. 61, figs. 5d, 5e; Newberry, Mon. U. S. Geol. Survey, 

 vol. 26 (Fl. Amboy Clays), 1895 (1896), p. 98, pi. 13, figs. 8-18; Hollick, Annals New York Acad. Sci., vol. 

 11, 1898, p. 60, pi. 4, fig. 8; Bull. New York Bot. Gard., vol. 3, 1904, p. 408, pi. 70, figs. 12, 13. 



These specimens, although fragmentary y show the characteristic shape and ner- 

 vation of the species quite satisfactorily. It is one of the most abundant species in 

 the Amboy clays, and some of the numerous diverse forms depicted by Newberry 

 (loc. cit.) are exactly like ours, all of which are considerably larger than the single 

 specimen figured by Heer from the Patoot beds of Greenland (loc. cit*) .

Celastrophyllum grandifolium Newberry? 



PI. XXXIII, fig. 8. 



OelastropTiyllum grandifolium Newb., Mon. U. S. Geol. Survey, vol. 26 (Fl. Amboy Clays), 1895 (1896), p. 104, 

 pi. 19, fig. 8; pi. 21, figs. 1-4. 



This specimen appears to be the lower part of a very large leaf of this species, 

 or possibly of CelastropJiyllum ensifolium (Lesq.) , a but its imperfect condition renders 

 satisfactory comparison impossible. Newberry also refers to this species and calls 

 attention to the resemblance between C. grandifolium and C. lanceolatum Etts., & 

 and says (loc. cit.): "With more material we may find that the species should be 

 united."

Gyminda primordialis, n. sp. 



PI. XXXIII, fig. 5. ♦ ' 



Leaf linear-obovate-spatulate, obscurely crenate above, entire below; nervation consisting of five pairs of 

 opposite, almost straight secondaries, which form acute angles with the midrib and ultimately coalesce into an 

 irregular submarginal nerve. 



This well-defined leaf is clearly different from any species hitherto described. Its 

 affinities are apparently with the Celastracese, and it may be compared with many
