While the book has now been surpassed in scope and coverage by the 2008 "Encyclopedia of Marine Gastropods" this is still a very popular and very useful title. This book is still very much in demand .This is a used copy but it appears to be almost in new condition. There is an inscription with the previous owner's name on the front fly-leaf. Revisions made in this printing appear on page 411.
