secundariis sub angulis acutis egredientibus arcuatis, subsimplicibus, clongatis, 
marginem adscendentibus vel inter se conjunctis ; nervis tertiariis dictyo- 
dromis. 
Obs. — Closely related to Celastrus elcenus, Ung., of the European 
Tertiary Elora, but differing from it by the leaves being more acuminate at 
their apices and somewhat obtuse at their bases. The nervation of the fossil, 
represented in Eig. 8a, enlarged, almost exactly agrees with that of the 
species just named. The petiole of our fossil leaf is incompletely preserved. 
Locality and Horizon. — With the preceding species. 
Celastrus Leeroyi, sp. nov. 
Plate XIV, Figs. 7, 7a. 
Sp. Char. — C. foliis coriaceis, petiolatis, oblongo-ellipticis, utrinque 
acuminatis, scrrulatis ; ncrvatione camptodroma ; ncrvo primario firmo, recto, 
nervis secundariis tenuibus, subangulis 70-75° orientibus, insequalibus, 
flexuosis ramosis ; nervis tertariis dictyodromis. 
Obs. — Corresponds to Celastrus Andromeda, Ung., from the European 
Tertiary Elora, and differs from it only by the borders exhibiting somewhat 
finer teeth, and by a more prominent primary nerve. There is another species 
from the same flora, Celastrus LEoli, Ett., to which our species is likewise 
related. But the latter deviates from it by a more narrowed apex, and by 
the secondary nerves quitting the primary one at more obtuse angles of 
divergence. Eig. 7a, enlarged, represents a fragment of the leaf, showing 
its borders and its nervation. 
Locality and Horizon. — With the preceding species. 
Celastrus Cunninghami, mihi. 
Celastrophyllum Cunninghami, Ettingshausen, Contributions, Part I, loc. cit. p. 40, PI. VI, fig. 5. 
Obs. — I have gained, on comparing this fossil described and figured in 
the first part of this Memoir with the preceding ones, a confirmation of my 
former conjecture respecting its ranging into Celastrineae. But on close 
examination of its nervation I have found that this species even belongs to 
Celastrus itself. In regard to its small and approximate teeth, as well as to
