Branxton Stage can be seen almost anywhere, where it is shown 

 on the map. A good occurrence of glacial beds has been exposed 

 by the new road-cutting on the Branxton to Elderslee road, 

 just before it reaches the Elderslee Bridge over the Hunter 

 River. The following is a list of the fossils from this upper part 

 of the Branxton Stage : — 



Zaphrentis robusta 



Crinoid stems. 



Trachypora wi/ki)>son i. 



Stenopora. 



Protoretepora ampin. 



P. konincki.

F. fossula. 



F. plicatula. 



Spirifer convoluta.

The upper limit of the Branxton Stage is well-defined by the 

 Bolwarra Conglomerate (" Muree Rock"), which forms the base 

 of the Muree Stage. This is a massive conglomerate, on which 

 very little grass or vegetation of any kind will grow, and which 

 forms a bold, bare outcrop, very useful indeed fur purposes of 

 geological mapping. This conglomerate passes upwards to a hard, 

 massive, somewhat calcareous sandstone, and the whole Stage 

 attains a thickness of about 400 feet. Both the conglomerate 

 and the succeeding sandstone contain numerous marine fossils, 

 there being a most remarkable abundance, in places, of the small
