The sheep kept throughout Britain up to the Iron Age were small, short-tailed, and varied in colour. These survived into the 19th century in the Highlands and Islands as the Scottish Dunface, which had various local varieties, most of which are now extinct (some do survive, such as the Shetland and North Ronaldsay). The Dunfaces kept in the Hebrides were very small, with white faces and legs; their bodies were usually white, but often black, brown, russet or grey. The fleece was short and soft and they were typically horned in both sexes, many of them having two or even three pairs of horns. The Dunface was gradually replaced with long-tailed breeds such as the Scottish Blackface and Cheviot; it died out on the mainland and eventually also on the Hebridean islands.
