At first I thought it was Neohelix albolabris based on the size (it's 24mm wide) and shape/size of the reflected lip. But, its umbilicate, and Neohelix is not. So... any ideas? Burch's 1962 field guide hasn't helped me here. Perhaps it's an introduced spp? I posted an earlier pic because it has an interesting predation scar pattern.
I'm pretty sure this one is Mesodon given that it's about 2/3 the size of the first and the other characters do match with the description.
The first one could be Allogona profunda. I can't tell from the picture how wide the umbilicus is.
