During the last few years, on several visits to Daylesford I 

 have collected fossils at a large number of localities. Many of 

 these have kindly been examined and identified by Dr. T. S. 

 Hall, a.nd the horizon of the beds determined. The greater 

 part of the collecting has been done between Sailor's Creek, on 

 the west, and the line of the Dry Diggings Road, on the east, 

 extending north and south over a distance of about six miles, 

 with Daylesford in the centre. The following notes are a sum- 

 mary of the information obtained at about sixty fossil localities. 



Previous Referexces. 



A geological survey of about 140 square miles in the vicinity 

 of Daylesford was commenced by Krause, and a progress report 

 dated Oct. 1, 1877, is contained in Progress Report No. 5 of the 

 Geological Survey of Victoria. He states that it is apparent 

 from the persistent westerly dip between the Loddon and Dayles- 

 ford, that the uppermost beds are exposed on or in proximity to 

 the meridional ridge, of which Wombat Hill forms a conspicuous 

 point ; that thence westward the beds are much folded and frac- 

 tured, and with these beds the principal auriferous quartz reefs 

 are associated ; that graptolites are abundant in these " upper " 

 beds ; and that the general strike of the beds near Wombat Hill 

 is 16 to 22 degrees west of north, but that further north it 

 becomes more meridional. The only fossils mentioned are Grap- 

 tolites frutioosus and Phyllograptus folium, which are stated to 

 be the most common species. 



The survey was subsequently continued by the late Norman 

 Taylor, whose report is contained in Progi-ess Report No. 8 of the
