P. 723, Explanation of Plate xxvii. — Figures 5 and 6 are interchanged. 



The following points may be noted, in which some modification or addi- 

 tion is required in the statements made ; — 



P.496— The stratigraphical disturbance in the Nundle region is greater 

 than formerly realised, and the details of the succession must be 

 taken with reserve. Particularl}^ is this the case with regard to the 

 breccias. 



P. 497 — The abundance of flows of spilite-lava has been disproved in the 

 communication iierewith. Recent work shows that the identity of 

 Bowling Alley Point limestone with that of Tamworth and Moore 

 Creek can no longer be maintained. The absence of medium- 

 grained tuff from the Tamworth Series is open to question. 



P. 500 — The conformity of the Baldwin Agglomerates on the Tamworth 

 Series has now been proved.
