The typical species of the family is found chiefly in the elevated tablelands of central Asia, and particularly of Tibet. These animals attain the size of a young roe deer, and the upper jaw bears prominent canine teeth. The males alone yield the musk, which is secreted by an abdominal gland of about the size of a hen's egg. The Tibet musk is most in repute, that known as Russian or Siberian being inferior in quality. Besides its familiar use as a scent, musk is employed medicinally as an antispasmodic.
