* no, that's fine. It is Cepaea nemoralis, with its great variety of
English names. They're ubiquitous in Ontario west of Toronto, up along
the Bruce (or now Saugeen) Peninsula. They're very variable in
coloration - except for the dark lip on the aperture - with variable
numbers of dark bands, and are abundant in Montreal with ground colours
that range from white to pink.
There are places along the 401 where they're massively abundant, and
Ottawa has Montreal-style highly coloured ones in the east, and
Toronto-style yellow ones (introduced at least by Wayne Grimm) in the
western portion of the city. Thinking they'd 'soon' be everywhere in
southern Ontario, we introduced them to Bishops Mills in 1981 and I had
78 of them alive on the road when I did the streets the day before
yesterday.
There's also Cepaea hortensis, which is very similar except for not
having the dark lip when adult, and which has been found in pre-Viking
caves on the Gaspe, and so somehow apparently made their way across the
Atlantic by themselves. There's a population at Sandbanks park, and a
19th Century population in Ottawa, near what may have been a portage,
and I'm working on the idea that it might have been founded by a snail
scraped of a long-ago canoe.
