272 T. S. Hart: 



wanath informs me that these were from material from a tunnel. 

 From his information, also, I make a slight verbal correction in 

 the last two localities. 



Mr. E. J. Dunn refers the beds mainly to the Castlemaine zone, 

 but in part to the Bendigo zone. This is apparently largely by 

 the weathering colours (Records Geological Sxirvey of Victoria, 

 Vol. II., pt. I., p. 10). 



General Outline of the Following New Observations. 



I have divided the area into three. My western localities are 

 from about the line of the strike passing through the Ajax Mine, 

 westward. All my fossils from these localities are referable to 

 the Bendigo series, but the localities are widely scattered, and 

 the field relations of the beds to one another are seldom ascer- 

 tained. 



Central Jielt. — In this the rocks are often well exposed and 

 much folded. Most of my observations are in this area. Bendigo 

 beds occur on its west side, and probably recur on anticlines 

 further east, associated with the Wattle Gully series, but no 

 higher beds have been demonstrated. 



Eastei'n Localities. — These are scattered localities east of the 

 Ballarat Railway, near Woodburn, and eastward from the Springs 

 at Hepburn, and one far east locality. In these also the field 

 relations of the beds are not observed. All the fossils ai'e refer- 

 able to parts of the Castlemaine Series above the Wattle Gully 

 Beds. 



I have numbered my fossil localities in order for facility of 

 reference, and described their positions in terms which allow of 

 their being readily located. The fossils identified by Dr. Hall 

 and his statements as to horizon I have marked thus : t- The 

 remainder of the names, confined almost entirely to common 

 forms, are from my own notes. 



Details of the Fossil Localitiks. 



Western Localities. 



In the Deep Creek at Eganstown black pyritic slates occur, 

 but no fossils were obtained.
