Variations in fifteen metrical measurements and six non‐metrical traits in 131 mink skulls were investigated. The skulls were subdivided geographically into three samples: Eastern Norway, Western Norway and Trøndelag. Separation into juveniles and adults was in accordance with the criterion that all sutures are closed in adults. This seemed to work well. No age or sex variations were found in the non‐metrical traits. Relatively little geographic variation found in either the metrical measurements or the non‐metrical traits indicated little genetic variation. Gene‐flow is regarded as one of the reasons for this.
