Collections of Clethrionomys glareolus Schreb. have been made from the mainland of north‐west Scotland and the Islands of Mull and Raasay. The skull of the Raasay vole is larger than that of the other two sub‐species although the proportions of all three are similar. The number of re‐entrants on the inner margin of the third upper molar declines as the tooth wears. On the islands, a higher proportion of newly erupted teeth have three re‐entrants. The three collections differ little in coat colour. Life expectancy is higher and breeding less intense in north‐west Scotland than further south. Comparatively little reproduction is performed by Scottish animals in their first year. There appears little basis for separating the Mull and mainland subspecies of Clethrionomys.
