Quite a few empty shells on the side of the track near the top
Possibly dead but I gave it a little soaking in case it was just overly dry
Another shell, this one definitely mouse damaged. :-(.
Found inside a predated Powelliphanta hochstetterii shell
Reference thumbnail is 15mm wide
Several empty shells found here, as well as one very dead one (ask me how I know) quite well distributed through the bush across altitudes and varying degrees of moisture.
