/ HALIOTIS KAMTSCHATKANA, Jonas. Living at a little below low tide at Port Neville, on 

 the mainland of British Columbia, north of Johnstoue Strait ; at Beaver Harbour, 

 on the north-east coast of Vancouver Island ; in the Goletas Channel ; and at the

 in Quatsino Sound ; abundant at some localities. 



The thick, calcareous operculum of this shell is used for ornamental inlaying,
