Disclaimer: The purpose of this site is to support the study of Cypraeidae. The evaluations for the status of taxa as well as the choice of forma-names in the checklists and the various articles were made partly on the basis of carefully conducted conchological studies whereas others are the result of my personal mood at some point and time. No responsibility for the correctness of any components of this site is taken. When reading any of the statements, decisions and choices reflected here, remember that nothing on this website represents a valid publication comparable to printed text in a scientific magazine. Changes may always occur and no guarantee is given that whatever I am writing here is going to be the final word. All of it is placed here merely for your information and viewing pleasure.
