Columella edentula. Near Jonas Creek, Bulkley Ranges, BC (Forsyth collection, 04.024.5439; height of shell 2. 4 mm).

The genus Columella appears to be represented in BC by two species: a tall, more cylindrical species called C. columella (G. von Martens, 1830), and a shorter, somewhat more tapered species that I provisionally call C. edentula (Draparnaud, 1805).
