Description ³

This is a small snail, under 10 mm in diameter, and is easily distinguished from almost everything else in SF by the three "teeth" or lobes in the aperture (species of Nearctula have teeth too, but the shells of those species are taller than wide and even smaller).

Habitat ³

This is completely anecdotal, but I (Ken-ichi) have only found them in relatively sandy soils, though in very different situations (moist, sandy former dunes under planted cypress; sheltered stream bed under oak/bay forest).

In SF ³

So far we've only found them under the cypresses just north of Lobos Creek.
