Identifying Land Snails and Slugs in Canada
by F. Wayne Grimm, Robert G. Forsyth, Frederick W. Schueller, and Aleta Karstad
ISBN 9781100124391, ©2009, published by the Canadian Food Inspection Agency, trade paperback, about 15 by 23 cm., 5.75 by nine inches, 168 page, illustrated throughout with black and white photographs, pencil and colored drawings, and very detailed information about these mollusks
Although this book was published not that long ago, it has been a book that is very difficult to find. This is only the second copy that I've come across. It is a thorough study of the native populations of the terrestrial mollusks found in Canada and it covers the many species of these shells that have been introduced to the country. A complete account is given for all of these mollusks at the specific and super-specific classifications. This is a used book that easily could pass as new save for some slight shelf-wear.
