length of the leaves at least half one foot, their texture pretty thick, without any trace of 

 secondary nerves. 



7. Proteoides Grevilei/eformis, Beer. PI. xxiii, Fig. 8. 



The specimen shows nearly the entire leaf; its point may be somewhat obtuse or long 

 acuminate ; its form is scythe-shaped, enlarged above the base and narrowed to a short 

 petiole. The medial nerve is well marked ; the secondary ones very thin, emerging in a 

 very acute angle, few, distant, and ascending along the borders. 



8. Andromeda Parlatorii, Heer. PL xxiii, Fig. 11. 



Tins specimen, like the former, completes one of Heer's species, of which only the mid- 

 dle part was known (Phyll., page 18, PL i, Fig. 5). The base of the leaf is decurrent on 

 a broad short petiole, which accordingly appears slightly winged, as in Andromeda revoluta, 

 Heer, of the Miocene. The nervation of both species is different. 



9. Magnolia alternans, Seer. Phyll., page 20, PI. iii, Figs. 2, 3, 4. 



Two good specimens of this species are in the collection of Dr. Lc Conte ; one like Fig. 

 3 of Heer, the other still larger than Fig. 4. They differ from all the specimens and 

 species from the N. Lignitic, by the strong deep secondary nervation, and by the form of 

 the leaves also. 



In the general or specific character of these cretaceous leaves there is nothing to force 

 a modification of the remarks made on the fossil plants of the Northern Lignitic. The 

 three first new species are without analogues in the Miocene flora, and the fourth, Sassa- 

 fras Le Conteanum, is of a peculiar type, represented heretofore only by Quercus Benzoin, 

 Lesqx., from Nanaimo, Vancouver's Island. This fact, and also the presence of Cinnamo- 

 mum Heerii, Lesqx., in the cretaceous of Nebraska, confirms the opinion of Prof. New- 

 berry, who, from personal examination in place, considers the Nanaimo's deposits as Cre- 

 taceous, and those of Bellingham Bay as Miocene* As the lithological compounds which 

 contain the fossil leaves of both localities are nearly alike, and as both formations have 

 species of the same genera, especially of Cinnamomum, I supposed them synchronous, 

 and referred them to the Miocene. For indeed Cinnamomum Heerii, of Nanaimo, is of a 

 type as evidently miocenic as Cinnamomum crassipes, of Bellingham's Bay. This recalls 

 to mind Cinnamomum Mississippiense, of the Northern Lignitic, which, as said above, is
