Persoonia Murrayi, Sp. HOD. 
Plate XI, Figs. 16, 17, 17a. 
Sp. Char. — P. foliis subsessilibus, coriaceis, anguste lanceolatis, 
utrinque acuminatis ; nervatione brocliidodroma ; nervo primario tenui, vix 
prominente ; nervis secundariis subangulis acutissimis orientibus, tenuissimis, 
ramosis, laqueos marginales formantibus ; nervis tertiariis vix distinctis, 
reticuli parce evoluti areolis angustis longitudinalibus. 
Ohs . — The texture, shape, and nervation of these leaves led me to the 
genus Persoonia. The leaves of P. lucida, R. Brown, show an extraordinary 
likeness to them. The above fossils are linear-lanceolate, narrowed towards 
both ends, and very shortly petiolate. A scarcely prominent primary nerve 
sends out some secondary ones which are very tine, and diverge from it at 
angles of 10°-20°. Their loops are approximate to the margin. The tertiary 
nerves form a narrow-meslied network, the meshes being oblong, to be seen 
on the fragment, Fig. 17, by a glass, and in the enlarged Fig. 17a. There 
scarcely seems to exist any point of difference between the fossils described 
and the leaves of the abovenamed living species, excepting that the former 
possess a somewhat broader lamina, and that their tertiary nerves and reticle 
are less developed. Our species deviates from the fossil ones hitherto 
described by its narrower leaves and by its nervation. 
Locality and Horizon. — Old Bose Valley Lead, with the preceding. 
GREVILLEA PROXIMA, Sp. UOV.

Sj). Char. — G. foliis submcmbranaceis, linearibus, integerrimis, basi 
in petiolum brevissimum attenuatis, apice obtusis ; nervatione brocliidodroma ; 
nervo primario vix prominente, recto ; nervis secundariis subangulis acutis- 
simis egredientibus opproximatis tertiariis inconspicuis. 
Ohs . — This species is closely related to Grevillea haeringiana, Ett., 
of the Lower Tertiary beds of Europe, and differs from it only by the 
approximate secondary nerves, and by the obtuse apex. 
The analogous Grevillea linearis, R. Brown, living in Australia, ex- 
hibiting the same form, a similar nervation, but a firmer texture of the leaf,
