exist. Still, the map is useful as far as it goes, and, consider- 

 iuLT 'lie amount of ground Krause had to cover in the time 

 allotted, the result as a whole is one we must thank him for. 



Mr. J. F. Mulder, in 1893, gave a list of a dozen species of 

 fossils from the Airey's Inlet limestone, but added nothing 

 further to our knowledge. 



The coast betw'een Spring Creek and Rocky Point, a dis- 

 tance of about two and a-half miles, has been briefly described 

 by Professor Tate and Mr. Dennant in 1893 and 1895. Mr. 

 Pritchard and I also discussed the relationships of the same beds 

 in 1896. 



Mr. A. G. Cauipbell. in a short sketch of the botany and 

 geology of the coast between Point Addis and Anglesea, mentions 

 the ■■ tall cliffs of mud-like material," and refers to " somewhat 

 similar beds beyond Anglesea, containing fragments of volcanic 

 scoria to the size of a football, and an occasional waterworn 

 basalt pebble," and thinks that " these clayey cliffs mark the 

 proximity of once-extensive lava-fields, long since disappeared." 



The fossiliferous yellow limestone of Rocky Point continues 

 along the coast to the south-west for about the third of a mile, 

 and on rounding a small point it is seen to overlie i^urple and 

 black, sandy clays, and to dip E. 10 degrees S. at 5 degrees or 

 6 degrees. The inward sweep of the bay has cut out the lime- 

 stones from the cliff face, and inland they have been removed 

 b}' denudation, their thickness being small. A couple of miles 

 further on Point Addis forms a low but prominent headland, 

 which is capped by the same limestone to a thickness, according- 

 to Krause, of 60 feet. Between Point x\ddis and the previously 

 mentioned point three reefs occur in the sea^ which are in a 

 straight line, and evidently are due to the induration of bottom 

 beds of the limestone. 



The Point Addis limestones are yellowish in colour, and in 

 places veiy concretionary and ragged. Quartz sand of a 

 roughened, granitic character is of frequent occurrence, and at 

 times forms thin bands. Indurated bands and patches are 

 common, and the rock is in places quite cry-stalline, a character 

 previously referred to by Mr. Pritchard and myself, and be- 

 lieved by us to be due to the impervious sandy clays on which 

 the calcareous series rests. The variety of fossils is small, but
