* I've sent Bill the 399 records I have (more than 1 km from our
introduction at home here), and I'm about to scoop up the records I have
by other observers, but I wonder if we can't have a bit of a Cepaea
festival on the list, and everyone who has seen them, send in species
(or just genus - https://en.wikipedia.org/wiki/Cepaea leads to
identification guidelines), location, and notes. With the locations
latitude & longitude would be easiest, but this is to be a map of the
whole province, so even vague records will be helpful.

If you've got a lot of records, you could send them to Bill directly.

My 137 databased Ontario Cepaea observations are all on iNaturalist where they can be viewed and downloaded. In total there are 12,666 Ontario Cepaea observations on iNaturalist, 12,477 of which have photo documentation.
