five uutenips yield JJ. bifidiis, some also yielding a luiinber of un- 

 desci-ibed specimens. Another unfossiliferous stretcli follows, but is 

 in turn followed by the most prolific area in the district. In the 

 area between Scott's Gully and New Chum Gully the outcrops are 

 so numerous that they cannot Avell be shown on a map of small scale. 

 The general succession from ^liddle to Upper Castlemaine is clear. 



Sections Compared and Additional Data. 



There are, then, in more or less detail, four lines of section 

 along Avhich the succession of beds from Upper Bendigo to Upper 

 Castlemaine may be traced. 



(a) That along the railway from Elphinstone Tunnel to 



Castlemaine, showing an ascent from Upper Bendigo to 

 Upper Castlemaine and beyond, then a descent to Lower 

 Castlemaine and a second ascent to Upper Castlemaine. 



(b) That along the water race to the south, where the succes- 



sion is the same, though more detailed. 



(c) That along the hills between these two lines showing 



Middle and Upper Castlemaine beds. 



(d) That east and west of the Chewton-Fryerstowu Eoad, 



where the succession from the Upper Bendigo to Middle 

 Castlemaine is well shown. 



A fifth line along the South Campbell's Creek water race and 

 hills from the Monk via Sebastopol Hill to Campbell's Creek shows 

 an ascending series from Lower Castlemaine to Upper Castlemaine. 

 From south of Fryerstown to the Limestone Creek the succession is 

 from Lower or Middle Bendigo upwards, but an area Ijetween 

 Guildford and Tarilta has not lieen examined. In addition a 

 somewhat incomplete record is seen north of Forest Creek, and here 

 the succession is the same. About the Vaughan-Tarilta " trap " 

 area ,(Ba 80 and 81)1 the beds pass from Upper Bendigo or transi- 

 tional Wattle Gully (T. fruficosiis and D. hifidus), to Middle 

 Castlemaine as one goes west. The lowest beds in the district are 

 those south of Fryerstown. 



The evidence of all these sections is corroborative and supple- 

 mentary, and, as they are parallel and contiguous, also cumula- 

 tive. Few places offer more opportunity for checking one's work, 

 and it is untlunkable that beds with a distinctive- and foreign facies 

 could exist l>etween the Middle and LTpper Castlemaine iDeds as dis- 

 tinguished by Dr. Hall and amplified here. The repetition of Mid- 

 dle and Upper Castlemaine beds to the east and west of Victoria
