Geology of Sydney. 
West of Mount Victoria, Devonian rocks occur on 
either side of the Cox River, about two miles south of 
Hartley. They are intruded by diorites, and are 
bounded on the north and south by granites, and 
to the east by the Upper Marine beds of the Permo- 
Carboniferous. 
Devonian Sandstones occur also near Cowra, on 
the slopes of the Canoblas near Orange, over a large 
tract of country from Wittagoona to Wilcannia, and 
Fig. 56 . — Spirifera disjuncfa . 1 A Devonian fossil found at Mount 
Lambie. The figures show various forms of this Spirifer. 
west of the Darling. It is highly probable that some 
of these separated areas were once continuous, and 
that we have now but a few scattered remnants of a 
once wide-spread formation. 
Land plants and marine shells occur in our 
Devonian rocks. Lepidodendron (Fig. 53) has been 
found associated with the brachiopods Spirifer dis - 
juncta and Rhynchonella pleurodon (see figures 56 
and 57). These last-named fossils are very plentiful
