I found some digital edition of some old books for education about Kobe in last year, one of them is Land snails in Kobe, published in 1979.

The book doesn't describe size of them, so I checked sizes. All three Clausiliidae I found was around 2cm, six of the book are smaller. And Hemiphaedusa attyrita only found in Arima. Remains are five.
