Carychium minimum from New Brunswick.

Last summer, during the New Brunswick bioblitz hosted by the New Brunswick Museum, the I found the first New Brunswick (and Atlantic Canada) record of Carychium minimum Müller, 1774. Read more about this in the short article published in Check List, the journal of biodiversity data. I am both a subject editor (for Mollusca) and the graphic editor.

Carychium minimum was collected along the shore of Mactaquac Lake, a widening of the Saint John River, upstream from Fredericton (45°52′06.5″ N, 055°44′44.6″ W.

My map of all North American records (that I know of) shows that this species is rather widely dispersed in Canada and the U.S.
