For some years my main interest as an Olividae/Olivellidae specialist is with the Caribbean Oliva species. It is an extreme difficult puzzle of which I think to notice the big picture: many different species and subspecies with large ranges of intraspecific variation. The strategy is to map out as many known populations as possible. After that type study (Duclos, Marrat, Petuch&Sargent etc.)and last but not least dna sequencing in order to confirm or reject the results of the morphological study. Without exaggaration, I need to study thousands of lots... Data and/or material is most welcome! (Bermuda, Jamaica, Mexico, Cuba, etc.). I can offer Olividae/Olivellidae for exchange or at least pay the shipping costs. Thanks in advance!
