Material examined. NW Australia, Kimberley, Town Beach, Roebuck Bay, 18°05’S, 122°17’E, 26 July 2003, coll. T. Compton —two complete specimens (WAM Z59480). Depth range. Collected on the beach. Measurements. Length 32.3 mm, width 15.6 mm; length 33.8 mm, width 14.0 mm. Remarks. Lingula anatina is very rare in the studied material, being found only at one locality. However, this species was already reported from north-western Australia (Emig 1982; Bryce & Sampey 2017). Its shell is elongate oval with subparallel lateral margins and a nearly straight anterior margin. The shell surface is smooth with distinct growth lines, of bright green to brownish colour. Lingula anatina is very widely distributed in the tropical and subtropical zones of the Indian and Western Pacific Oceans (Emig 1982, 1984, 1997).
