intercalated with the upper part of the limestone. This clay is 

 remarkable, chiefly for the great preponderance of trochiform 

 shells, but otherwise resembles the section described by us on the 

 other side of the valley. 



There is little doubt that the polyzoal limestones of Wautn 

 Ponds, Maude, Curlewis, and Batesford, are on the same horizon, 

 though slight differences in the faunas certainly exist. 



At Flinders and at Airey's Inlet,* at Curlewis and at Maude, 

 a polyzoal rock rests on the older basalt. This in its turn, at 

 Maude, overlies a sandy limestone containing a fauna which is 

 the equivalent of that of Spring Creek. At Waurn Ponds the 

 limestone overlies a clay in which fossils have not as yet been 

 found, but which Mr. Wm. Nelson statesf to closely resemble 

 that of Spring Creek. 



The Waurn Ponds rock can be traced almost uninterruptedly 

 from M'Cann's quarries, which is the best known exposure, as far 

 as a quarry on the south side of the Barwon River opposite the 

 end of Pakington Street, Geelong. The locality of this (juarry 

 we shall indicate by the name of North Belmont. The rock here 

 is a sandy limestone, and the fauna shows a stronger relationship 

 to that of Spring Creek on account of tlie greater number of 

 moUusca which it contains ; though, unfortunately, most occur 

 merely as casts. The dip of the beds is well pronounced being 

 E. 40" S. at 10° This would carry them below the Belmont 

 clays shown in the oft quoted well,l and Mr. J. Mulder informs 

 us that limestone was struck at the bottom of tlie shaft after 

 passing through the clay l)eds. 



The polyzoal rock then appears to be antecedent to the clays 

 of the Lower INIuddy Creek type, and to overlie beds with a 

 fauna similar to that of Spring Creek. 



It will be seen that we almost entirely reverse the sequence as 

 interpreted by Piofessor Sii- Fredk. McCoy, and adopted by the 

 (xeological Survey. According to this view the clays of 

 Morningttm, Southern Moorabool Valley (Fyansford, etc.), and
