The study of these mollusks has always been a challenge because at first glance many of these shells are similar in appearance. They do not have color or discernible patterns that are usually are first things that we look at when we dealing with the Cypraea in the Recent Fauna. And, of course there are no DNA studies that are possible with these shells. So, we have little to go on other than the shape and formation of these shells to guide us towards an identification. In this book the authors have taken extreme care in studying these shells and pointing out for us the key factors that have been used to separate these fossil species one form another. The shells are divided into those of the Miocene and Pleistocene epochs and each of these epochs is divided into the species found in the many different fossil bed formations found in Florida. The description of the shells is thorough and the photographs are of top quality. Usually several specimens of a species are shown. This is a book that should be on the bookshelves of every cowrie collector, every one interested in past history of shells in Florida, and of course, those with an interest in fossil shells. I know of no other book this complete and this well researched about these shell than this one.
