inhabit Asia, lias mostly coriaceous lanceolate leaves, with approximate, carnp- 
todromic secondary veins, ascending towards the margin. It is more especially 
the leaves of Castanopsis argentea , De Cand., var. Martabanica, Do Cand. 
(PI. VII, fig. 8), C. tribuloides, De Cand., C. Tungurrut, De Cand., and 
C. concinna, De Cand. (PI. VII, fig. 9), which, in addition to the pecularities 
named, possess also the marginal characters and form of leaf of the described 
fossil. In this latter the tertiary veins are wanting. But as in the leaves of 
Castanopsis, especially in those of the analogous species quoted, the tertiary 
veins and the reticulation are not prominent, the underside being covered 
with a tomentum, the absence in the unfavourable stone matrix of Dalton of 
the tertiary veins and the network of the fossil Castanopsis leaf is easily 
explained, and the circumstance may even be regarded as an additional proof 
of the correct determination of our fossil as a Castanopsis. The species 
approaches the Castanopsis mephitidioides, Gey. sp., from the Eocene Flora 
of Borneo, but differs from it in its less ascending secondary veins. 
I named this species in honor of Mr. George Bentham, of London, the 
venerable chief of British botanists, and a great writer on the Flora of 
Australia.

Obs. — Leaves from the so-called Travertin, near Hobart, show- 
ing the greatest similarity with willow leaves. All the characters point to 
Salix, the texture, the form of the leaf, the dentation of the margin, and 
the venation. The last, shown enlarged in Fig. 8a, must be regarded as
