During a long walk in Montreal this afternoon, Deniz and I came upon some railroad tracks that didn`t seem to be in use anymore. A few meters from the tracks there was a low wall of large blocks possibly of limestone. They are visible in the picture behind me.

On one of those blocks, shaded by grasses and other plants, were a bunch of tiny land snails. They had become dormant attached to the rock. Without the help of an instrument of magnification other than my camera, or a key for snails, I am identifying them tentatively as Pupilla muscorum.
Here is one in the palm of my hand.
