Twenty non‐metrical variants are described in the skulls of Grey seals ( Halichoerus grypus ). Ten of these have been classified in samples of 47 skulls from Orkney and 18 from the Hebrides. The frequencies of one variant were “significantly” different ( P ≏1%) in the two samples. This result means that there is some genetical distinctiveness between the two samples and suggests a way of characterizing and hence comparing seal groups.
