Brief visits in 2013 and 2015 to the Jewish cemetery in Monnickendam, province of North-Holland, the Netherlands, resulted in the finds of three additional species of terrestrial gastropods: Vallonia pulchella, Arion circumscriptus and Arion hortensis. In all, 25 different species are now known from this ancient cemetery (which was established in 1677): 16 snails and 9 slugs.
