Annual report 2023 of the ‘Neptunea’ group

The inquiry has been posed by individuals both within and outside the group: where do we want to go with this subsidiary of KonBVC? What goals do we wish to achieve? Where do we position ourselves within the entire spectrum of national and international associations? And why do we need a separate magazine?

First and foremost, the role of a subsidiary is to gather members who cannot or do not wish to make the distant journey to the main headquarters in Antwerp. The BVC-Coast calendar is carefully arranged to allow members to attend meetings at both locations (Ostend and Antwerp). While half of our members eagerly take advantage of this, it is unfortunate that we seldom or never welcome chairpersons, board members, or other members of KonBVC to our gatherings.

Our association has a unique vision of seashell collecting: each monthly meeting lasts about three hours, during which members are introduced to collecting techniques, guided through the maze of identifying and classifying shells, provided access to an extensive library, given the opportunity to exchange/purchase shells, and attend PowerPoint presentations on excursions, new species, or an overview of a particular genus or family.

The emphasis of our association lies clearly in the identification of shells, often lent by the MNHN, resulting in the discovery of new species or the clarification of synonyms. The outcomes of these meetings are published in the ‘Neptunea’ magazine and distributed worldwide through the website <neptunea.org>.

The magazine was launched when dissatisfaction arose with the A5 format of ‘Gloria Maris’ in the early 21st century. We deemed it inappropriate for our articles to be published in such a format, especially considering our intention to display a large number of color plates with detailed images. Additionally, we preferred publishing articles in a distinctive style with a critical analysis of so-called new species or the publication of species with images highlighting differences with similar species through keywords. We aim to avoid lengthy, often meaningless descriptions, making the articles practically useful for quickly identifying species – a perspective highly appreciated by international readers.

As long as we have sufficient articles and budgets, the magazine will maintain its independent course. However, it will be discontinued in the event of the current responsible publisher stepping down. Within the working group, no one feels inclined to take on that task.

It has been observed that most collectors – even after attending meetings for decades – still possess only a superficial knowledge of how shells should be identified. The original description is rarely consulted, and due to the high cost of current literature (books and journals), inspiration is often sought on the worldwide web or through social media. Not all sources are equally reliable. A binocular microscope for examining protoconch and microsculpture is, therefore, a primary requirement, but photographing shells and editing them with the necessary software is an additional asset. Our association offers this service to its members: study material is submitted in advance, photographed via focus stacking, and presented at the next meeting for discussion and critical review. This avoids manually passing study material from one collector to another during meetings.

We have also decided to publish all previously published articles online, and the PowerPoint presentations from our meetings can be freely accessed on the website.

Thanks to an increase in membership fees, we can now financially survive without problems and continue to enjoy a highly appreciated year-end reception annually. The sponsor has also made new efforts to improve lighting and heating in the meeting rooms.

Finally, we would like to express our gratitude to all members who make the long journey to Ostend and especially to those who have selflessly manifested themselves in the past year, notably Steve Hubrecht, who has provided several interesting presentations and support for the study work. Encouraging is the article by Arne Ghys describing a new Pseudamussium species and presentations with PowerPoint by new members (Jan Libbrecht, Bart Wursten, and Jean-Paul Van Bellinghen). We also want to extend our appreciation to Delphine Clement, the silent force behind the regular updates of the website.
