Diagnosing Cowry Species
by E.L. Heiman

ISBN 9659058802, published in 2004, published by the author in Israel, paper-back in spiral binding, 160 pages, 21 by 30 cm. (8 by 11.75 inches), 43 page size color photographic illustrations and numerous black and white photos, charts and tables throughout the text

This book has been out of print for a while and we were glad to be able to get a copy of it to offer. The author takes a very different to determine the species of cowries that he considers to be valid. He has created a number of conchological characteristics that are found in the shells in the genus Cypraea.  The presence or the absence of one or more of these characteristics is then used to determine the validity of that shell as a species.  In all 268 species are in the study. Of these the author has determined that 211 of these are recognizable species, 14 are subspecies and 19 are synonyms. The remaining shells are rare and have not been studied or have not had their characteristics quantified. Whether you agree or disagree with the hypothesis of this book it is certainly a different way of seeing things. I'd forgotten until I thumbed through the book that several of the photos in the book are from slides that I loaned to the author. A small claim to fame indeed.  This is a used book and the previous owner has written his name inside the back cover. There is a small torn spot on the cover by the lowest of the metal spiral bands used for the binding and also it has a few bends  in the cover.
