In the \ sheets (23 S.W. and 23 S.E.) dealing with this portion 

 of the district, some confusion exists as to the volcanic rock;?. 

 The large outcrop forming the Bellarine Hills is mai-ked as older 

 volcanic, of which it is regarded as forming a typical locality. 

 On the west side of the road from Portarlington to Drysdale, the 

 lettering in the two places indicates newer pliocene overlying 

 older volcanic in one case close to the cliff, while the cliff section 

 shows an outcrop coloured to represent lower volcanic (' pliocene '), 

 but not lettered. On \ sheet 23 S.W. the same outcrop is shown 

 running along past Clifton Springs, with one intermission, to a 

 short distance past the dyke we have alluded to. This inter- 

 mission should not occur, as the ash beds crop out continuously 

 along the beach at this place. Both these separated portions of 

 the same outcrop are marked V. 1, 2, 3, that is, as the legend 

 shows, lower volcanic ('pliocene') basalt dolerite, anamesite and 

 lava, while V. 4 (ash, conglomerate, &c.) is omitted, although a 

 section of over two miles in length is exposed. This is not all, 

 for a note near the parish boundary and close to the volcanic 

 outcrop states that "the basalt outcrop of the Bellarine Hills 

 probably underlies the pliocene tertiary sands and ironstones as 

 far south as the heads of the creeks falling into Corio Bay." So 

 that this outcrop is coloured ' pliocene' and alluded to as 

 'miocene;' while the true state of the case is that it is uncon- 

 formably overlain by the clays which were then called miocene or 

 oligocene but which are now regai'ded as eocene. 



The Curlewis Eocenes. 



This will be a convenient name for this section, as the hamlet 

 of Curlewis is situated on the Portarlington Road, about a mile 

 to the southward. 



It is probable, as will presently appear, that the sequence of 

 eocene beds here is similar to what occurs in the Moorabool 

 Valley,* that is, that the polyzoal rock, where it occurs, is the 

 underlying member of the series, though we were unable to 

 absolutely prove the succession. 



At the first place where we noted the eocene beds (parish 

 boundary), they consisted of blue clays resting on ash beds, the
