Snailing Links
Here are all the good links for identifying molluscs that I know (besides the obvious). I'll collect them here mostly for my own convenience, but also for whoever may need them. Sadly, not all the materials are in English. Feel free to post your favorite links in the comments.
- Swedish website: very slick, a list of Swedish species and distribution maps. Nice pictures, some species have multiple pictures of different morphs, which is especially nice. Somewhat lacking when it comes to bivalves. In Swedish.
- German website: a similarly slick database, everything in 𝔊𝔢𝔯𝔪𝔞𝔫. Species, distribution maps (well hidden) and even identification keys. Especially noteworthy: 𝔇𝔢𝔯 𝔖𝔠𝔥𝔩𝔦𝔢ß𝔪𝔲𝔫𝔡𝔰𝔠𝔥𝔫𝔢𝔠𝔨𝔢𝔟𝔢𝔰𝔱𝔦𝔪𝔪𝔲𝔫𝔤𝔰𝔰𝔠𝔥𝔩ü𝔰𝔰𝔢𝔩 (whatever that is), the Pea Clam section (with pretty pictures!) and the accompanying 𝔈𝔯𝔟𝔰𝔢𝔫𝔪𝔲𝔰𝔠𝔥𝔢𝔩𝔟𝔢𝔰𝔱𝔦𝔪𝔪𝔲𝔫𝔤𝔰𝔰𝔠𝔥𝔩ü𝔰𝔰𝔢𝔩 @amr_mn, may be relevant to your interests.
- Carnegie Museum is the only resource on American snails that I know. Snails of Virginia section is especially good, also has a snails of Pennsylvania section, less complete.
- Molluscs of Belarus (in Russian). Not so great pictures, but lots of info on various species.
- Swiss Database (thankfully in English) - mostly distribution maps. Also pretty slick.
- Ukrainian Gastropods: Gural-Sverlova may have contributed a lot to it? Lots of valuable info, though scattered all over the maze-like web-page.
- British distribution maps.
- French Clausiliids - not a website, but a paper with a key. Includes sub-species, very detailed.
- Nature of Latvia - Latvian species lists and distribution maps. Sad, pitiful.
- Another American page
Comments
This is great, thanks!
Would you mind if I add links to various PDFs? (Mine are almost all freshwater bivalve sources rather than gastropods.)
No, no, add all the links you like, what's the worst that can happen?
North American Sphaeriids:
(The best resource is a book with a list price of $50 but available for much higher prices secondhand. This is probably the only link I'll provide to something for purchase.)
Mackie, G.L. 2007 Biology of Freshwater Corbiculid and Sphaeriid Clams of North America. Ohio Biological Survey.
Link goes to publisher, it's about halfway down that page: Volume XV.
Errata: Distributions are presented in maps, tables, and descriptions. They are inconsistent.

Also has the Gastropods, Unionids, Corbicula, and Dreissena found in the State
Errata: List of Pisidium s.l. includes one Australian species (hallae) and one New Mexican species (sanguinichristi).
Unionid list has since expanded by one species Utterbackia imbecillis.
Thanks for the info!
British Columbia (Western Canada)
E-Fauna BC Atlas, with many great photos from @ian_gardiner (and probably good ones from other people)
Freshwater Gastropods
Land Gastropods
Freshwater Bivalves, mostly Sphaeriids
I'm not sure how complete these are (though the Unionids are).
Species names link to distribution maps.
I found this website about Molluscs, that might be a little out of date. (I'm guessing it's an Austrian or German website?)
It contains some info and facts about Molluscs in general.
https://www.molluscs.at/
There are sections for Gastropods, Cephalopods, Bivalves, etc.
On the top left, there is a search bar that allows you to search about different familes, etc. For example: Arionidae, Pomatiidae...
I hope that it might help in some way.

Distribution maps for Sphaeriinae (using old taxonomy, but other than the changes from Pisidium to Euglesa or Odhneripisidium for all but P. amnicum, the only change is that P. hibernicum is now E. parvula).

Free PDF from Google Scholar, seventy-smth pages. Haven't read into it yet but its certainly worth sharing.
"European Mollusks"
https://www.rkapeller.eu/start.html
English and German.
Seems quite extensive: ID notes and photos for most species.
Separate sections for Freshwater and Marine and Bivalves and Gastropods.
"Welcome to the most comprehensive database with determination key for European mollusks.
The database is still under development and can be used for the determination of marine bivalves, marine gastropods, freshwater bivalves and freshwater gastropods at the moment. For terrestric gastropods it is expected to be available by March 2024. Other classes should follow in 2025."
