fossils have been discovered will their comparison with the nearest living 
species he possible. I do not find the fossil now described related to any one 
published. 
Locality and Horizon .— Old Rose Valley Lead, with the preceding. 
Hakea Duttoni, sp. nov. 
Plate XII, Figs. 11, 11a. 
Sp. Char. — II. foliis rigide coriaceis petiolatis, lanceolatis utrinque 
angustatis apice acuminatis, margine argute spinoso-dentatis ; nervatione 
brocliidodrorna ; nervo primario valido, apicem versus attenuato, recto ; nervis 
secundariis tenuibus subangulis acutis variis orientibus, approximatis ramosis 
inter se conjunctis ; nervis tertiariis e latere externo secundariorum angulis 
acutis exeuntibus, abbreviatis, ramosis, rete macrosynammato. 
Ohs . — Prom its characters this fossil may best be classed in Ilakea, and 
is there related to species which possess stiffly coriaceous leaves. A com- 
paratively thick carbonaceous substance, partly loosened from the fossil, indi- 
cates the evidently firm texture of its leaf. Besides, it is distinguishable by 
its teeth, ending with strong spines, a character found in Ilakea. 
Our fossil agrees in some points with Lomatia, for iustancc, L. helicioides, 
Sap. sp., L. aquensis, Sap., of the European Tertiary Plora, but they are only 
distantly related to it. The network, represented by Pig. 11a, (enlarged), 
shows broken nervules, corresponding to those of Proteacece. 
Locality and Horizon. — Witlierden’s Tunnel, Two-mile, near Enuna- 
ville (Vegetable Creek township), on Vegetable Creek Main Deep Lead; brown 
carbonaceous clav, under basalt.

laeiniis vel segmentis lateralibus valde approximatis plus minusve falcato- 
lanceolatis basi angustatis obliquis adnatis subdecurrentibus, margine antico 
dentatis ; terminalibus subrhombeis lobatis; nervatione brochi-craspedodroma;
