primario recto, basi valido, apicem versus angustato ; nervis secundariis 
distinctis, subangulis 40-50° orientibus, approximate, leviter curvatis, apicem 
versus abbrevatis et subrectis ; nervis tertiariis tenuissimis ramosis, reticulum 
tenerrimum formantibus. 
Ohs . — A leaf of this species, Pig. 18, has been collected at Vegetable 
Creek. It is smaller than that from Dalton, already described by me, but its 
nervation is better preserved. The latter, represented in Pig. 18 a (magnified), 
exhibits a tender network of the tertiary nerves. As for the other characters 
of the leaf, especially the form, margin, and nerves, as far as they are com- 
parable, the present leaf agrees avcII with that from Dalton. Another specimen 
I refer to this species has been found at Elsmore. 
Locality and Horizon. — Witlierden’s Tunnel, Two-mile, near Emma- 
ville (Vegetable Creek Township), on Vegetable Creek Main Deep Lead. 
Dalton, near Gunning; in hard siliceous grit, reposing on Silurian rocks. 
Newstead, near Elsmore ; in concretionary ironstone (earthy limonite), 
associated with basalt. 
Quercus Edelii, sp. nov. 
Plate IX, Figs. 13, 13a. 
Sp. Char. — Q. foliis subcoriaceis, obovato-oblongis, apice obtusis, mar- 
gine grosse dentatis ; nervatione brocliidodroma ; nervo primario finno, recto, 
excurrente ; nervis secundariis tenuibus, angulo subrecto egredientibus, 
ramosis, ramorum laqueis pluriseriatis, aux prominentibus ; nervis tertiariis 
tenuissimis, dictyodromis. 
Ohs. — This species is closely allied to Quercus serra, Ung., of the 
Possil Plora of Parschlug, in Styria, Austria. The form of the leaf, the 
peculiarly toothed borders, and the type of nervation are nearly the same in 
both species. The Australian one only differs by its thinner secondary nerves 
and their more obtuse angles of divergence (see the network of Quercus 
Edelii, Pig. 13a, in comparison with that of Q. serra, Pig. 14a, both magnified). 
Locality and Horizon. — Witherden’s Tunnel, with the preceding 
species. 
Quercus Dampieri, sp nov. 
Plate IX, Figs. 15, 15a. 
Sp. Char. — Q. foliis coriaceis, petiolatis oblongo-lanceolatis, remote 
dentatis, basi attenuatis, apice paullo angustatis ; nervatione craspcdodroma ;
