Changes in the coat and skin of a mouflon sheep were followed from the age of three months to the age of twenty-one months. The birth coat was shed between four and six months of age and there was a marked moult the following spring. During both these moults the coat was lost as a single mat. The wool of the under-coat was shed only once during the spring moult, whereas the hairs of the outer coat were shed a second time in summer, but this was less obvious than the spring moult.
Details of the histology of the skin and of fibre shedding are given in addition to incidental observations on growth and the horns.
