nervo primario basi prominente, apicem versus tenui ; nervis secundariis sub- 
angulis acutis arcuatim orientibus, marginem adscendcntibus, inter se 
conjunctis ; tertiariis vix conspicuis. 
Obs.— Closely related to Lomatia aquensis, Sap. var. gracilis. But our 
species possesses more approximate secondary nerves, its teetli being turned 
more towards the apex of tlie leaf. The nervation, represented in Big. 15 a, 
magnified, is almost equal to that of the named species from the Tertiary 
Flora of Provence. The texture seems to have been less firm. 
In the American Tertiary Flora, Lomatia microphylla, Lesq., may be 
considered analogous to our species, from which it only deviates by the entire 
borders of its leaf. 
Locality and Horizon. — Fox and Partridge’s claim, between Rose 
Valley and the Red Hill, 2 miles from Emmaville (Vegetable Creek Town- 
ship); ironstone shale from Newer Leads (stanniferous), under basalt. 
Lomatia castaneje folia, sp. nov. 
Plate XII, Figs. 2, 2a, 3. 
Sp. Char . — L. foliis coriaceis, angustc elongato-lanceolatis, apice longc 
acuminatis, margin© remote spinuloso-dentatis ; nervatione mixta, craspedo 
droma ct brochidodroma; nervo primario prominente, apicem versus attenuate ; 
nervis secundariis tenuibus, subangulis 50-00° orientibus, subflexuosis apicc 
ramosis partim inter se conjunctis; nervis tertiariis tenuissimis, ramosis 
dictyodromis ; rcticulo valde evoluto, aperto. 
Obs. — A very peculiar leaf which bears strikingly the facies of 
Lomatia, though by its shape and its craspedodrome secondary nerves we are 
reminded of Castanea. But in the formation of the network, it essentially 
deviates from the latter by the open nervulcs (see Fig. 2a, magnified), and 
agrees with the leaves of Proteaceoe. Among these it is characterised by its 
mixed nervation. Of the species of this order here described, only those of 
Banksia exhibit the same type of nervation, the latter possessing secondary 
nerves which are alternately brochidodrome and craspedodrome. Our fossil, 
however, is easily distinguishable from Banksia by the teeth of its borders, 
and by the facies of its network.
