This book follows the trend today toward books on molluscs being photo iconographies with very little or no description. While it is good to have photographic references like this one, it is disappointing that we are left on our own to seek another source for information about the shells. I guess that it is much easier to assemble a book of photographs than it is to write descriptive material about them. The photographs in this book are good but they are not up to the high standards that you'll find in other contemporary books. The shells of a species sometimes appear to have been taken at different times and then these photos were assembled into a single photograph which then offers different degrees of lighting and of sharpness within a single photo. In short, the book is good for what it is, but one wishes that it would have been a lot better if more time and effort went into it. But problems and all, it is still the most up-to-date guide to this important family of mollusks.
