Leiden, June 1993. recorded A well-preserved complete test and a test fragment ofthe loveniid echinoid species Echinocardium cordatum (Pennant, 1777) are from late Pliocene strata (Upper North Sea Group, Oosterhout Formation) as exposed at the de Kauter locality at Nieuw Namen.

Spine form and arrangement correspond exactly to what has been described in the literature for Recent and fossil representatives of this species, which has been exhaustively studied in almost every respect (see e.g. Moore, 1936; Nichols, 1959; Buchanan, 1966; Ernst et al., 1973; Smith, 1980a, b, 1984; David & Laurin, 1991 and Kana- zawa, 1992). This complete test was collected from the sandy unit between 1,95 and 3,25 m below surface in Janssen's (1983a, b) section, and has subsequently been deposited in one of the authors' (JJV) private collection. It will be donated to the Hulst municipal museum.
