The occurrence of the family Marginellidcs in the South Australian 

 seas has hitherto been unrecorded. 



Species of Marginella have been known to inhabit the eastern shores 

 of this continent, whilst the sub-genus Hyalina was first recorded in 

 1871, and E?~ato in 1877, as Australian. Examplar species of each of 

 these have been found by me in our waters. They are eight in number : 

 five of Marginella, two of Hyalina, and one of Erato. Two of the 

 Marginellas are identified with known species, but the others I believe 

 to be undescribed.
