Island, Point Piper, and other places near the Heads, off George's 

 Head (12 fathoms, weeds), and between Ball's Head and Goat 

 Island (18 fathoms, broken shells and stones)." 



Mr. Brazier also showed specimens of Alarginella pulchella, 

 Kiener, from Norfolk Island, a species reputed to have been first 

 found at Sydney, specimens of which, indeed, of late years have 

 been found at Long Bay, near Sydney, by Mrs. G. J. Waterhouse; 

 also specimens of pumice collected at Norfolk Island, with a query 

 as to its probable source; a specimen of Astele multigraria, Dunker, 

 from Spencer's Gulf, S.A. ; and samples of a supposed volcanic (?) 

 rock from Watson's Bay to the north of the jetty.
