On 10th April I posted photos of a native snail feeding on fungi. I returned to the same location yesterday and while searching through some leaf litter, I came across another one. To my untrained eye looks to be the same species, Stenacapha ducani. This one was much less shy, coming out of it's shell and allowing me to get some better photos.
Edit: I told I had an untrained eye. This one turns out to be Stenacapha hamiltoni. See comments below for an explanation of differences in shell morphology.
