Two new finds of the Yellow slug Limacus flavus, Fam. Limacidae, are here reported from West-Terschelling, a small village on Terschelling, a Wadden Sea island in the north of the Netherlands. The rediscovery of this exotic species in West-Terschelling comes exactly 40 years after its first report from that village. All the specimens (respectively three adults and one juvenile) were encountered on the same rainy day. The common name Yellow (earth-)slug is here preferred in the Dutch text over the official name Pale (earth-)slug, not only because of its general colour but also because of its sticky yellow slime.
