Passing thorn under review, we happened on a narrow-leaved variety of 
Berchemia multinervis, A. Braun, which had been discovered in the strata 
of Sagor (see Ettingshausen, Eoss. Elora von Sagor, Denkscli. K. Akad. 
Wissenscli, Wien, vol. xxxvii, PI. XVI, figs. 8-10). This shows remarkable 
ascending secondary veins, and in its form approaches very nearly the 
Bhamnece from Dalton, only the above mentioned basal veins are wanting 
also in the fossil Berchemia. We have, therefore, grounds enough for the 
erection of a special genus for the Bhamneoe just described, and which may 
be regarded as the ancestral genus of Pomaderris. 
The species is named after [Sir Joseph] Banks, the English naturalist.

Sp. Char. — E. foliis rigide coriaceis lanceolato-oblongis obtusiusculis, 
integerrimis ; nervatione camptodroma ; nervo primario apicem versus sub-

Ohs . — A leaf whose strong, somewhat recurved margin indicates a 
remarkably rigid texture. At the base it can be restored into an oblong, 
almost lanceolate leaf, which is narrowed towards both ends and obtuse at the 
apex. The midrib is somewhat flexuous towards the apex, and not prominent 
on the upper surface of the fossil, whilst the under side is covered by the rock 
material. 
Owing to this unfavourable circumstance, even the course of the fine 
and remarkably acute-angled secondary veins, but more especially their 
behaviour at the margin, cannot be observed with sufficient accuracy. In 
one place near the margin I thought I could perceive an indication of the 
marginal vein, with which the secondary veins are connected. Tertiary veins 
and reticulation have not been preserved. The form of leaf, texture, and 
venation just described are found in Eucalyptus , viz., in E. teretiuscula, and 
others (sec Ettingshausen, Blattskelete der Dicotyledonen, PI. LXXXY, fig. 
17). As the assumption that Eucalyptus was not wanting in the Tertiary of 
Australia is, at all events, more probable than the contrary, so much the more
