direction and the basaltic flows in the Latter. The syncline 

 pitches to the north, and the axial line can be drawn in a 

 northerly direction for about one mile, but beyond this it is 

 uncertain. The rocks are, as indicated later, mainly of Yeringian 

 age, and as the syncline, therefore, is of importance structurally 

 and palfBontologically, I suggest jthat the name of the " Merriang 

 Synclinal " be given to it. 



Tliere is a third possible structural feature — a fault. As 

 already noted, the strike of the eastern side of the syncline is 

 abuit X. 40 deg. E., the strata dipping at about 10 deg. The 

 striko of the western leg of the Whittlesea anticlinal along the 

 Cemetei-j' Hill road is from 5 deg. to 10 deg. west of north, with 

 a dip at an angle of about 50 deg. If the strike lines be con- 

 tinued to the north of the road just mentioned, they will meet 

 at. an acute angle. The only satisfactory explanation is a fault, 

 and apparently a strike fault, so far as the Whittlesea anticlinal 

 bed.s are c mcerned. The pitch of the Merriang Synclinal may 

 have been caused by this fault, and the rocks of this fold would 

 be on the downthrow side. The amount of the displacement is 

 at present unaseertainable. The probable course of the fault 

 for about 2A miles is indicated on the map. How far it continues 

 cannot at present be said. Perhaps a cross fault occurs near to, 

 but to the west of, Mount Phillippi. The section accompanying 

 this paper indicates the general structure along the Cemetery 

 Hill road. 



FoSSILIFEROUS SECTIONS. 



These, with the exception of XII. and XIII., have been dealt 

 with, as regards the fossils, by Mr. Chapman in the Appendix. 



Some of the sections are excellent, both for fossils and for 

 structural evidence. Amongst these are III., VII., YIII. and 

 XII. At the last named, Plem-odictyum megastomum, Dun, is 

 the only fossil yet determined. Section III. is identical with 

 Bb 15 on Quatrer Sheet 3 N.E. At section VII. a richly fossil- 

 iferous ferruginous sandstone occurs under the shelly limestone. 

 Section VI. is the richest of all for fossils (trilobites and 

 brachiopods being especially abundant) ; but the rocks are 

 merely small blocks thro\vn out in grubbing trees. Most of the 

 other records are either very small sections or outcrops, and 

 where the dip is not indicated on the map, there is not sufficient
