Résumé :	A multivariate comparison of morphometric differences was undertaken on populations of Pontophilus norvegicus from four Atlantic and one Mediterranean locations. Multiple discriminant analysis revealed clear morphometric differences between Atlantic and Mediterranean populations, with the Atlantic populations exhibiting a low degree of separation. The underlying variables responsible for this discrimination are shown not to have any operational taxonomic utility and, hence, no sub-specific status is attached to the respective populations.
