a northerly direction, which are of interest, as no determined 

 moUuscan remains have hitherto been recorded from this area. The 

 deposits have, however, yiekled Dinosaurian bones which have been 

 referred to in literature by Dr. A. S. Woodward. Another locality 

 in New South Wales for opalized fossils has quite recently come into 

 prominence through tlie discovery ot Ceratodtis remains at Baradine, 

 situated some 90 miles S.S.E. of Walgett, which Mr. Chapman has 

 just described, a fact of much interest, since this is a genus of fish 

 which still survives in Queensland rivers.
