In New Zealand it may, however, be noted that gvaptolites 

 occur, and Sir James Hector* gives some woodcuts of species 

 found there. These are, however, not named in the work, and 

 the figures alone merely give general characters. All the figures 

 might be intended for forms which occur in the Wattle Gully or 

 in the T. friiticosiis zone in Castlemaine, and the former is the 

 more probable hoi'izon. 



The results obtained may be tabulated as follows, the beds 

 being arranged in descending order : — 



1. Zone of Loganograptiis Logani, occurring at Castlemaine 



and I3arriwill. 



2. Zone of Tetragraptus caditceus, occurring at Castlemaine. 



3. Phyllograpto-caduceics zone, occurring at Castlemaine. 



4. Burns' Reef beds, occurring at Castlemaine. 



0. Wattle Gully beds, occurring at Castlemaine and (?) New 

 Zealand. 



6. Zone of Tetragraptus friiticosus, occurring at Chewton, 



Bendigo, Spring Plains, Tarilta, Upper Loddon, 

 Daylesford, Gisborne, and to noi'th-west of Lancefield. 



7. The Lancefield shales. 



With regard to the extension of the zones in tlie line of strike, 

 the important effects produced by " pitch " must be recognised, as 

 has been so fully indicated by Mr. E. J. Dunn in his "Report on 

 tlie Bendigo Goldfield." There is evidently a strong northerly 

 pitch in the great Chewton anticline, as, although I have carefully 

 examined the area north of Forest Creek, I have never been 

 able to find traces of any but the second and third zones. The 

 sixth zone again occurs at Tarilta, approximately on the strike of 

 the highest indicated zones at Castlemaine. 



Auriferous Ba?ids. — The fact that the auriferous quartz-veins of 

 Victoria occur in fairly definite bands of country, separated by 

 non-auriferous bands of lithologically similar strata, is one that 

 early impressed itself on observers, and it is difficult to say who 

 first noted the fact. Sir Alfred Selwyn records it, and Mr. Evan 

 Hopkinst also mentions it. In a recent report of the Mining 

 Department an old letter to the Governor of the Colony fi'om
