consists of twenty islands, islets, and rocks, in Spencer Gulf. 

 Revesby and Spilsby are the only islands on which water

A sandy island for the most j^art, and with a very coarse-

The ripe fruits of Posidonia australis. Hook., /., were 

 especially abundant in Spencer Gulf, off and on the shores
