Brighton coast. The reference to Pliocene age and identity with 

 the Flemington beds was unquestioningly adopted. The rocks 

 were divided lithologically into a fourfold series. The author 

 stated that there is an unconformity in the beds. We have had 

 the pleasure of going over the coast sections in company with Mr. 

 Hart, and have examined some of these unconformities, which 

 undoubtedly exist. The best we have seen exposed is at Red 

 Bluff, Sandringham. We are not, however, inclined to attach 

 much importance to these small local irregularities. The rapid 

 alternations of sediment, the current bedding, and the occurrence 

 of fossil trees, pointed out by Mr. Hart, imply conditions favour- 

 able to the deposition and removal of strata, which would produce 

 unconformities, but would not indicate any difference in age. In 

 most places the beds succeed one another with no appreciable 

 break. 



In the same year the authors (13) indicated that the Flemington 

 beds were probably Eocene, and definitely referred the blue clays 

 found by sinking and boring at Newport and Altona Bay to the 

 Eocene. 



Messrs. Tate andDennant(15) definitely classed the Cheltenham 

 beds as Eocene, and a few months later Professor Tate (16) again 

 expressed the same view. 



Localities. 



1. Beaumaris (east of the Hotel). 



This is the richest fossil locality that is exposed, and is 

 probably the source of most of the fossils recorded from " Chel- 

 tenham " and " Mordialloc." A slight anticlinal brings up the 

 deeper beds in which the fossils are most plentiful, the sti'ike 

 being parallel to the coast line. In the northern corner of the 

 bay the eastern limb of the arch suddenly plunges at an angle of 

 from 20° to 25° in the direction E. 25° S. A little further to 

 the south-west the dip decreases somewhat and swings a little 

 more to the southward, being E. 40° S. at 17°, so that the 

 anticline has a slight pitch in a south-westerly direction. The 

 beach floor has long been a favourite collecting ground, and 

 sharks' teeth, cetotolites and fragments of bone were formerly 

 very commonly found. Many years ago it was noticed that
