Excerpt from West American Shells: A Description in Familiar Terms of the Principal Marine, Fresh Water and Land Mollusks of the United States Found West of the Rocky Mountains, Including Those of British Columbia and Alaska In order to adapt this book to readers of West Coast Shells, the old name of a species has been retained in parentheses, whenever a change has been made. A com mon name has also been given to each species described, usually a more or less free translation of the accepted Latin name. As might be expected, much difficulty has sometimes been experienced in deciding between the claims of rival synonyms, and it is not to be hoped that all will accept the author's conclusions; an honest endeavor, however, has been made to select the name which has been adopted by the best authorities.
