escarpment, and some of the beds are eonglomeritic. Many of the hard 

 beds are highly fossiliferous, eontaiuing numbers of Astarte major, large 

 Gervillea, n. sp.j Trigonia Smeei, Gri/pheea, Pleurotomaria, &e., &c. 



At Iddurghur, on the crest of the scarp, numbers of these fossils, 

 the bivalves being in a fine state of preserva- 

 tion, strew the summit and sides of the hill. In 

 many cases both valves remained together, and some single ones were 

 beautifully weathered out, showing the clean surface and muscular 

 impressions of the inside of the shell. The same fossils occur again on 

 the northern slopes of the hills, but the large Gervillea, several inches 

 in length, just now mentioned, which occurs with them, could never 

 be obtained perfect. 



Above the strata which form the long northern slopes here are 

 yellowish and greenish-gray shales in bands of from 10 to 35 feet, with 

 hard flaggy layers coming on, as they pass into the low ground ; red 

 ferruginous beds also occur containing fossil-wood and strong widely 

 ribbed Ammonites of the same species as those at Trummo, but some 

 light colored sandstones near them appear unfossiliferous. A coarse 

 calcareous conglomerate above these contains a large, narrowly ribbed 

 Astarte, &e., and a ferruginous bed above has Belemnites, and large ill- 

 preserved bivalve shells. A thick group of shales and flags succeeds 

 these, separated by a holey layer from some 50 feet of variegated red 

 and white sandstone, which passes under soft, white, half compacted 

 sandstone, a three foot bed of bole, and some dry rusty sandstone, with 

 white blotches and patches of quartzose gravelly nature. All these with 

 various northerly dips may be seen in the Saynar nuddy near Burrooria.

one east of JBurrooria, and m the neighbouring 

 low country, red and yellow thin-bedded sandstones with numerous 

 bands of shale are either horizontal or dip slightly to the north.
