46 T. S. Hall: 



the locality is reiuarkiil)le for the extreme abundance of Cassi- 

 iliilus (lustrdlKte (Duncan), while M oiidxi'lld fom pta (T. Woods) 

 is almost as plentiful. 



The purple and Ijlack clays, which are seen in cliff section to 

 underlie the limestones, are weathered to a lighter hue in their 

 more superficial parts, and it is chiefly to this weatherintr that 

 the various beds measured by Krause, and recorded in a note 

 •on his map, are due. This section is the one previously men- 

 tioned by Daintree as containing pyritic casts of mollusca and 

 unaltered foraniinifera. I have never carefully searched for 

 fossils, and have seen none in the beds. Daintree evidently 

 regards the black beds as the equivalent of the marine series 

 of Bird Rock, though he is not clear on the point. On rounding 

 Point Addis, and traversing half a mile of sandy beach, a small 

 point is met with, consisting of ferruginous sands, and quartz 

 conglomerates. This is known as the Black Rocks. From here 

 to the mouth of the Anglesea River the coast is marked by 

 vertical cliffs of black sandy clays. These beds are similar 

 to those on the other side of Point Addis just referred to, and 

 .are of a very striking character. Beyond the mouth of the 

 river, after passing a small strip of sand dunes which mark the 

 extent of oscillation of the mouth, we encounter an outcrop of 

 ferruginous conglomerates and sands interbedded in the black 

 sandy clays, but of only small lateral extent. They foi'm a small 

 point on the beach, and are very similar to those at the Black 

 Rocks. The sands and clays form cliff's of gradually lessening 

 height from here to the shoreward end of Point Roadkniglit, 

 which is formed entirely of dune limestone. 



At the mouth of the Anglesea River the older tertiary 

 forms the east bank, and a hard outcrop occurs on the beach. 

 It also forms a reef bare at half tide a short distance oft' shore, 

 while another reef of perhaps a similar character, the " Here- 

 ford Reef," from the name of a ship wrecked on it, occurs a mile 

 to the east. Banked against the older rock at the river mouth 

 are a few small patches of indurated sand forming a small 

 raised beach. In this I found several i)aired valves of Chume 

 scalarina in the living position, and some large examples of 

 Lampania australii. Krause, on his map, marks " sandy lime- 

 stone " here, and probably refers to this small outcrop.
