Abstract
Ensis directus occured for first time in high number in the French par t of the North Sea in spring 1991. Identification of specimens smaller than 15 mm is difficult because of easy confusion with Ensis arcuatus . For longer animals, a length/height ratio of 6:1 is a reliable crite rion of identification for Ensis directus after the three other consta nts and reliable characters described by de Boer (1984).
