Welcome to the 'New Zealand Mollusca' website.

This website has evolved from my passion for New Zealand Shells - collecting, studying, and photographing them.

Here I have endeavourd to provide an up-to-date checklist of all New Zealand species, with images of the more common or well-known species.

I am constantly adding more information about each species, including sizes, habitats, and common names of some species.

I have recently updated the site to include Google Maps to show some of the locations where species have been recorded. Some of these locations are only approximate. I will be updating the locality data and fine-tuning the locations as I go.

References to other publications are also being added to the checklist, as I go through my reference library. I have also begun adding references to some of the New Zealand Molluscan Publications, eg. "Poirieria" and "Cookia". These are listed with the Species Details, when species are mentioned in the publication. Click here for a list of references and publications.

Type Localities are also being added to species details.

The checklist has now been supplemented with a page list for each family.

If you have any suggestions, enquiries or questions, please email me. Any comments would be appreciated.
