I was looking at this photo and I noticed I have what seem to be two succineids in this sample. Compare the one on the upper right to the one in the lower middle. There is a distinct difference here that I hope isn't just ontogenetic.
From top to bottom: an egg, Columella alticola, Pupilla muscorum, Vetigo cf. modesta, a succineid (Catinella sp.?), and Discus cf. shimeki
Discus cf. shimeki and one round snail egg.
