Sections after this character appear in a length of coast-line of about 

 20 miles, extending from Hallett's Cove on the north to the south side 

 of Aldinga Bay. The upper Aldinga series I place on the same horizon 

 as the upper series of the Murray cliffs ; and the lower Aldinga beds I 

 regard as equivalent in part to the middle and lower Murray series, 

 but on the whole inferior to them. The coral bed at Hallett's Cove is 

 probably coterminous with the upper series of the Aldinga section. 



The following list includes all known South Australian corals, cor-
