Day 166: We have quite a few species of snail in the Pacific Northwest and among the most common is Allogona townsendiana, the Oregon Forest Snail. The shell is brown and marked with thin, light lines when these snails are young, but the colour is only a papery layer which peels off in age, revealing a blue-white base. That said, Allogona can be confused with other species in age, and the most definitive feature for field identification is the absence of a tooth-like structure in the aperture. The Oregon Forest Snail is quite toothless!
