Obs . — The fossil represented in Tig. 1 agrees in every particular with 
the ternate leaf of a species of Ceratopetalum ; the larger leaf fossil with 
the terminal leaflet, and the smaller with a lateral leaflet. The two leaves 
lie so close to one another, that from this alone it might be inferred that they 
arc the component leaflets of a compound leaf. The common petiole, to 
which the leaflets must have been attached by their rather long petiolules, 
has been lost subsequently to the detachment of the leaflets. In the leaves 
of existing species of Ceratopetalum, the leaflets have only very short petio- 
lules. The species described corresponds to C. bilinicum , Ett., to such an 
extend that I am almost inclined to regard these fossil plants as identical. The 
only difference is that C. JFoodii lias somewhat larger leaves and longer 
petiolules. Ceratopetalum americanum, Ett.,* is an analogous species in the 
North American Tertiary Elora. 
I named this species in honor of Harrie Wood, Esq.,f who has done 
much for the promotion of geological science in Tasmania. £

( hry sophy Hum rnonopyrenum, Ettingshausen, Blattskelete des Dicotyladoncn, PI. XXXIX, fig. 10). It is different 
with the leaf fossil called Suphulm coriaceus in the work quoted, Fig. 14. It does not betray any remarkably 
strong texture, nor does it show a recurved margin, but certainly a very decided asymmetry at the base. This 
fossil belongs to quite a different plant than that represented in Fig. 13, which may be allowed to retain the 
designation Sapindus coriaceus. 
I dedicated this new Sapotacean, of which the Sapotacites lanceolatus, Ett., is the analogue in the European 
J ertiary Flora, to its discoverer, Professor E. D. Cope.

Ceratopetalum americanum , sp. nov. ( Myrica acuminata, Lesq., loc. cit., PI. XVII, figs. 1-4). 
Obs. These leaves are mostly similar to those of Ceratopetalum hatriniyianum, Ett., from which they differ 
only in the somewhat more acuminate marginal teeth. Myrica acuminata, Ung. , to which the fossils in question 
have been referred by Lesquereux, have longer acuminate leaves, broader below the middle, and a different venation 
(compare Ifcer, I ertiarflora der Schweiz, vol. ii, PI. XXIX, fig. 20). Myrica Zachariensis, Sap., and M. 
arr/iUi, Ileer, sp., with which the fossil under consideration has also been compared, belong to different genera, 
the first likewise to Ceratopetalum, but the latter to Cary a.
