The whole of the above twenty-two species are obtained in 

 Miocene deposits elsewhere, whereas only five are recorded as 

 ranging into the Eocene. 



Of the above twenty-two species seventeen have been 

 specifically named, including one doubtful identification ; the 

 remainder ai'e as yet undescribed species. 



The seventeen described species occur elsewhere as follows : — 



Muddy Creek Miocene - - 17 (1 doubtful). 

 Jemmy's Point Miocene - - 17 ,, 



Beaumaris Miocene - - - 13 



The Quarter-sheet bears the same colour from the top of the 

 hill down to the river flat, the whole series being referred to 

 Older Pliocene. Towards the foot of the hill, however, the 

 character of the beds changes, and, though we found no fossils, 

 it is probable that the lower pax't of the beds is Eocene, as 

 fossiliferous beds of this age occur less than half a mile lower 

 down the stream and are in their upper part of similar litho- 

 logical character. 



The presence of marine Miocene beds here, \vhere they are so 

 clearly overlain by volcanic rock, is of importance when viewed 

 in connection with a deposit recently described by Messrs. J. 

 Dennant and J. F. Mulder at Shelford, about eighteen miles to 

 the westward of the present locality (3). Pinding the marine 

 Miocene beds resting on basalt, and basalt also occurring further 

 from the river, and at a higher level, these authors have assumed 

 that the two basaltic outcrops belong to the same period and 

 practically to the same flow. Arguing from these premises they 

 state their view to be that the basalt forming this portion of the 

 Western Plains is not • younger than Miocene, and they ascribe 

 the presence of the marine Miocene beds in that locality to a 

 submergence after the gorge had been partly cut out by the 

 stream. An examination of the section which they give, 

 however, shows that a different interpretation may be placed on
