During the years 1993 to 1996 surveys were carried out on 89 sandy beaches around the Irish coast from Malin Head in the north, along the west and south coasts, and oil the east coast north to Dundalk. The hermit crab Diogenes pugilator (Roux, 1829), which had not previously been reported from Irish waters, was found on eight beaches between Portnablagh, Co. Donegal, in the north-west and Red Barn Strand, Co, Cork, in the south. The records given here represent a northward extension from its reported northern limit in Wales. Data are provided on the distribution and ecology of the species in Irish waters. In 1999 D. pugilator was found again on one of the surveyed beaches and exoskeletons were recorded at a ninth location, Bunduff Strand, Co. Sligo, showing that populations were still present in Irish waters.
