Book Reviewed by Richard Kent
Finally the highly anticipated sequel to “The Guide to Worldwide Cowries” by Lorenz and Hubert has been published. There is both good and bad news about the new book. We need to point out that “Cowries, A Guide to the Gastropod Family Cypraeidae” by Felix Lorenz and published by Conch Books is split into two volumes. At this time only Volume 1 is available.
First the good news. Everything one could possibly want to know about Cowries, live and extinct, is thoroughly discussed. This is the de nitive book on the subject.
The bad news. It’s 644 pages of exhaustive text is intended for the advanced collector. Photographs are minimal; Volume 2 will be the photo book. The price is a whopping $199 retail. The way the volumes are split up, readers will need to purchase both.
The rst 181 pages cover in seven chapters: Cowries and Man, Animal Morphology, Reproduction and Development, The Adult Shell, Habitat and Distribution, DNA, and Cowrie Evolution. It’s fascinating and essential reading that one needs to make the most out the second half of the book.
The balance of the book is a systematic Cowrie
Identification Guide, updating the original “Guide” to the present with numerous new subspecies and species. Collectors will especially get new insight on South African and Australian Cowries. Every species is given scientic name, synonyms, cited references, size range, habitat, distribution and a discussion. The descriptions are concise, cut and dry. One misses the air that Wells had in his book on Cones. There are also comparison charts and maps. Lorenz illustrates each species and subspecies with a photo of the dorsum and base of a typical specimen. All are shown the same size so the minute Cypraea microdon is illustrated at an identical size as Cypraea tigris. Even though all are shown the same size, the length of the discussion for each species varies greatly. It is obvious Lorenz has his favorites! He chooses to devote much space to discussions on nomenclature and DNA. Lorenz is what is known as a “splitter” (as opposed to “lumper”) and has introduced dozens of new names himself. At times the detail in these discussions can be overwhelming, even to an advanced collector.
Collectors could nd much that is controversial and open to debate. One of several instances that stood out to me is that according to Lorenz, Cypraea tigris tigris is an Indian Ocean cowrie whereas Cypraea tigris pardalis is the Philippine variety, but he fails to cite the original descriptions and type specimens to back this up. Having dealt with shell dealers for years, pardalis is an all white tiger with minimal black spotting and no dorsal line, just like the one illustrated in the groundbreaking Burgess book. It would be interesting to see that if one dozen tigers from various populations in the Indian Ocean were mixed with one dozen from the Paci c if any expert could correctly separate them. Lorenz says they have different DNA.
I read the book cover to cover taking a full week. Because I am an advanced collector I nd the book essential. It greatly added to my understanding and enjoyment of the hobby. I can’t wait for volume 2 with all the photos to be published.
A word to Mr. Lorenz – take only the information that is essential to the beginning and casual collectors and publish a condensed, concise photo guide. The hobby needs such a book. It will be a best seller!
