A school master of Thurso in Caithness, William Munro, wrote in a report in THE TIMES on September 8, 1809 that twelve years earlier he had been walking along Sandside Bay shore when he saw what he first thought was a naked woman, sitting on a rock and combing her light brown hair. The face was fatty round, with reddish cheeks and blue eyes. If the rock where the woman sat had not been so dangerous for swimmers, Munro would have thought it was human. After a few minutes it dropped into the sea and swam away. Others had seen it too.

The island of Benbecula in the outer Hebrides, about 1830, women cutting seaweed reported they had met a creature of female form playing happily off the shore. A few days later her dead body was found two miles from where she had first been seen. The description of the creature was recorded thus, “the upper part of the creature was about the size of a well-fed child of three or four years of age, with an extraordinarily developed breast. The hair was long, dark and glossy(有光泽), while the skin was white, soft and tender. The lower part of the body was like a salmon(鲑鱼). ”
