This monograph has been about 10 years in the making and I am delighted to finally see it in print. It is a pleasure to have a ready reference work on this interesting family in a single reference work. The book is very well laid out and it is very easy to work with since the illustrations and text information about each of the shells are on the same pages. The illustrations are in black and white and most are photographs and some are drawings after the original descriptions of the shells. There is no index of the species that are included in this book but instead the shells are arranged alphabetically by genus. I wish that an index were included since it would make it a lot quicker and easier to find what you are looking for, but there is an advantage to this format too. It is a little like when you are looking for something in particular in a dictionary or an encyclopedia and you keep getting side tracked from your original search by interesting things that you come across while searching for your original goal. Many of the shells that are illustrated are holotypes or paratypes of their species and it is obvious that the author has gone through a great deal of effort to round up this material from many diverse sources. If any proof is needed as to how much research went into this book you need only look at the bibliography section which accounts for almost 50 pages of the book. Each species is carefully cross referenced as well as remarks about each of the species. I don't know how many shells are covered in this work but I'll guess that there are several hundred shown and referenced. This is an excellent book and it is one and it is a work that should provoke a interest and understanding of this family of shells
