Tn the main portion of this report (l, d), an account was given 

 of the region extending from Warialda, the northern limit of the 

 visible part of the Serpentine Belt, to the Namoi River. It was 

 intended to survey in greater detail the complex region between 

 the river and Moore Creek, thus joining on to the area alread}- 

 mapped in the Tamworth District south of Moore Creek, and 

 with the survey of the Loomberah District to be considered in 

 Part vii., of this series of papers, in order to complete the mapping 

 of the Great Serpentine Belt, in greater or less detail, from 

 Warialda to Nundle. The writer's removal from Australia 

 makes this now impossible. It seems advisable, therefore, to 

 place on record the work already done, upon which was based 

 the mapping of this area in the Plate accompanying Parts i. and 

 vi.; and to indicate the modifications required, as shown by later 

 information obtained by the writer, by Lieut, Aurousseau, B.Sc, 

 M.C., and by Mr. S. M. Tout, and by Mr. L. J. Jones. The 

 present communication, therefore, is a compilation of incomplete 

 information gathered by several workers, and will serve chiefi}' 

 to draw attention to the interesting nature of the material 

 awaiting further research. The writer's thanks are due to the 

 generous permission given by the gentlemen named to make use 

 of their work, and to the Government Geologist, Mr. J. E. Carne, 

 for permission to show, on the accompanying sketch-map, the 

 boundaries of the limestones in the area between Attunga Creek 

 and the Naxiioi River, which are copied from the surveys of Mr.
