As is usually the case with the Carboniferous marine 

 fauna in New South Wales, brachiopods largely prepon- 

 derate, while the individuals are usually quite small. There 

 is, however, one fossil bed on McOrae's farm (Portion 4, 

 A. A. Cos. subdivision), which is crowded with the large 

 brachiopod, Productus barringtonensis. The rock is a 

 coarse tuff, 10 to 20 feet thick, and this fossil is the only 

 one found in it. 



III. The Kuttung Series. — These follow the Burindi 

 Series conformably, and have a total thickness of 1750 feet; 

 they consist mainly of lava flows. 



(a) The Conglomerates. — These have been taken as the 

 basal beds of the series; they outcrop on the western side 

 of the Gloucester Buckets where they are about 150 feet 

 thick, while the pebbles are small. Further to the south 

 where they cross the Rawdon Vale Road, they are some- 

 what thicker and the pebbles are coarse averaging from 4 

 to 6 inches in diameter. These conglomerates are probably 

 the equivalent in this district of the Wallarobba con- 

 glomerates previously described for the Wallarobba-Olar- 

 encetown district 1 some 50 miles to the south.
