but this could be due to the nature of the rocks on the land 

 which was being denuded to provide the sediments. If 

 this land consisted largely of Devonian strata the sediments 

 found in the Burindi Series are just what one might expect 

 to find. 



3. Comparison of the Devonian and Carboniferous 

 marine fauna. — No marine fossils of Devonian age, other 

 than radiolaria have been found in this district, but the 

 Devonian marine fauna from adjoining parts of north-eastern 

 New South Wales is well known. Very few Devonian 

 species have passed upwards into the Carboniferous Period, 

 neither did many of the genera. No passage beds have yet 

 been found. Taking all of the facts into consideration, it 

 may be said that while no angular unconformity has been 

 proved, there is certainly a strong disconformity between 

 the strata of the two periods, and that important crustal 

 movements occurred at the close of the Devonian Period. 



O. The Gloucester Coal Measures. 



These coal-measures, besides occurring over the area 

 shown on the map, extend southwards past the village of 

 Craven, down the valley of Ward's River to within a few 

 miles of Stroud Road. This southern area has sometimes 

 been referred to as the Ward's River Coal Measures. It 

 will be seen that this coal basin is about 35 miles long, and 

 from five to eight miles wide. No detailed surveys have 

 yet been made of this little known coal basin, and the 

 author himself has made only a cursory examination of the 

 measures in the immediate neighbourhood of Gloucester. 

 Here they consist of shales, sandstones, grits, conglomer- 

 ates, and coal-seams totalling upwards of 1,000 feet in 

 thickness. A fairly good section of these strata may be 

 seen in the railway cuttings immediately to the north and 

 south of the Gloucester railway station. In the cutting 

 to the north of the railway station numerous coal seams
