Pupilla hebes

Crestless Column

Pupilla hebes

Pupilla hebes. Vicinity of Isaac Lakes, Ruby Range, southern Yukon (Forsyth collection no. 11.007.3920); height of shell: 2.9 mm.

Across much of northern Canada, from the Yukon and northern British Columbia, east through the Northwest Territories to northern Ontario, there is a Pupilla sp. quite unlike Pupilla muscorum of southern Ontario, Quebec, and elsewhere. I’ve provisionally used the name P. hebes for these. Compare with a specimen of Pupilla muscorum in an earlier post.

Widespread Column

Pupilla muscorum

Pupilla muscorum: Along the Saint Lawrence River and chemin des Ancêtres, northeast of quay, Grondines, Portneuf MRC, Québec. Snails were on small pieces of stone along a low bank/outcrop, as well as lower, in areas that clearly would be inundated during spring flood.
