The genera are Ovis (sheep), Capra (goats) and Hemitragus (tahr).
The short-horned Asiatic goats of the genus Hemitragus receive mention in the article Tahr; but it may be added that fossil species of the same genus are known from the Lower Pliocene formations of India, which have also yielded remains of a goat allied to the markhor of the Himalayas.
Under the name of Hemitragus jemlaicus, it typifies a genus in which are included the wariatu, or Nilgiri ibex (H.
