This book is a worthy update and revision to Bratcher & Cernorhorsky's "Living Terebra" and increases the number of species in this family from 268 to 313. Apart from the new material this book has color plates which are an improvement over the previous work. Like so many publications today the text is minimal and you will not want to get rid of your old "Bratcher" if you are interested in much more complete descriptive material about each of the shells. The photographs are very sharply detailed and the book is easy to work with and it is well indexed to let you "cut to the quick" if you are simply looking for a clear illustration of any particular shell. It is a book that is worth having for any shell library and it is an absolutely essential work for anyone working with this popular family of shells.
